(First embodiment)
FIG. 1A is a diagram illustrating a state in which the seat projects outward from the door opening, and FIG. 1B is a diagram in which the seat illustrated in FIG. 1A is extracted. FIG. 2 is a system configuration diagram of the vehicle seat control device according to the first to third embodiments of the present invention. FIG. 3 is a schematic view showing a boarding / exiting position where the seat projects outward from the door opening, as viewed from above the vehicle.

  The vehicle seat control apparatus 1 according to the first embodiment is a seat supported so as to be movable between a storage position P stored inside the vehicle and a boarding / exiting position Q projecting outward from the door opening 3. 5 is provided. The seat 5 is moved between the storage position P and the getting-on / off position Q by a sheet moving mechanism 7 constituted by a link member or the like. For example, the seat moving mechanism 7 may be configured such that the seat 5 is moved along the guide rail and the seat 5 is rotated by a rotating mechanism interposed between the guide rail and the seat 5, and any moving mechanism can be applied. It is. An actuator 9 is connected to the sheet moving mechanism 7, and the sheet 5 is moved by the actuator 9 via the sheet moving mechanism 7. The door opening 3 is provided with an openable / closable vehicle door, and the vehicle door is opened and closed by an actuator 29 via a door opening / closing mechanism 27.

  The seat 5 includes a seat surface 5a that can slide in the front-rear direction of the seat 5, and a seat back 5b that is attached to the seat surface 5a and can tilt in the front-rear direction. Side supports 5c are provided on both sides of the seat back 5b to suppress the occupant's lateral shaking. The side support 5c is attached so that the included angle can be adjusted. A headrest 5d is attached to the upper end of the seat back 5b so as to be movable in the vertical direction.

  The seat 5 is provided with an actuator 11, and the actuator 11 drives the seating surface 5a, the seat back 5b, the side support 5c, and the headrest 5d via each link mechanism.

  Control means 13 such as an ECU for controlling the driving of the actuators 9 and 11 is connected to the actuators 9 and 11. The ECU (Electronic Control Unit) 13 is composed of a microcomputer, and has a ROM for storing a control program, a readable / writable RAM for storing calculation results, a timer, a counter, an input interface, and an output interface. .

  The ECU 13 controls the actuators 9 and 11 of the seat 5 based on the information on the passenger and adjusts the overhang state amount of the seat 5. For example, the amount of extension state of the seat 5 includes a boarding / exiting position Q where the passenger gets on or leaves the seat 5, an amount of extension W of the seat 5 outward from the door opening 3, and a storage position P. The moving speed of the seat 5 to and from the getting-on / off position Q, the rotation angle θ of the seat 5 at the getting-on / off position Q, the height R of the seating surface 5a of the seat 5 at the getting-on / off position Q, the seat slide amount at the getting-on / off position Q Direction) S, the height T of the headrest 5d at the getting-on / off position Q, the included angle α of the side support 5c at the getting-on / off position Q, the reclining angle β at the getting-on / off position Q, and the like. The moving speed of the seat 5 between the storage position P and the getting-on / off position Q includes the rotational speed of the seat 5 at the getting-on / off position Q and the reclining adjustment speed at the getting-on / off position Q. The rotation angle θ of the seat 5 is an angle formed by the vehicle side end side and the longitudinal axis of the seat 5, and the overhang amount W of the seat 5 is the vehicle side end side and the outer end portion of the seat 5. Is the distance. Furthermore, to increase the reclining angle β is to tilt the seat back 5b backward.

  In addition, as information on the passengers, for example, the physique of the passengers (height, weight, waist height, etc.), age, exercise ability, health condition, speed of the passengers approaching the vehicle, physical problems (degree of physical problems, Body defect location, etc.), clothing (color, design), etc.

  An image processing unit 17 that processes an image captured by the camera 15 is connected to a camera 15 such as a compound eye camera that captures passengers and the like. The ECU 13 is connected to the image processing unit 17, and data processed by the image processing unit 17 is transmitted to the ECU 13. In other words, the image of the passenger taken by the camera 15 is subjected to image processing by the image processing unit 17 and transmitted to the ECU 13. The ECU 13 recognizes passenger information based on the transmitted processed image.

  For example, the ECU 13 gets on and off based on the distance and vertical angle between the camera 15 and the passenger (an angle between a line connecting the camera 15 and the upper end of the passenger and a line connecting the camera 15 and the lower end of the passenger). The height of the person may be calculated. Further, the ECU 13 may calculate body dimensions such as height based on the processed image from the image processing unit 17 and estimate the weight based on the calculated dimensions and a prestored model pattern. The load meter 19 may be built in the seat 5, and the weight of the passenger may be detected by the load meter 19. Based on the processed image of the passenger from the image processing unit 17, the ECU 13 recognizes the image of the walking speed, the stride, the left / right swing, the posture, the color of the clothes, and the like of the passenger and estimates the age of the passenger. Further, the ECU 13 recognizes an image of the walking speed, stride, left-right swing, auxiliary equipment such as a cane, etc. based on the processed image from the image processing unit 17, and determines the defect level and position of the passenger (upper body). , Lower body). Note that the ECU 13 may recognize the passenger information from user identification information transmitted from a transmitter 21 such as a radio remote controller key or a smart key described later.

  Further, the ECU 13 detects and determines that the user (passenger) is about to get on the vehicle or is about to get off the vehicle. When the ECU 13 detects / determines signs of getting in / out of the user (described later), the ECU 13 executes the control of the actuators 9 and 11 using the detection / determination as a trigger to adjust the overhang state amount of the seat 5.

  It may be arbitrary what kind of sign the ECU 13 determines that the user is going to get on and off. Regarding the boarding determination, for example, when the door lock is released remotely from the outside of the vehicle using the radio remote control key 21, the user who has the smart key 21 is detected within a predetermined range, etc. You may determine that you are about to get on. Here, the smart key 21 is a key having a function of automatically performing a door lock release, a steering lock release, and the like by automatically collating the ID code with the vehicle through two-way communication. . Further, the ECU 13 may determine that the user is about to get on the basis of the image of the passenger from the image processing unit 17.

  On the other hand, regarding the getting-off determination, the shift lever is put in the P (parking) range when the IG is turned off when the passenger gets out of the vehicle through the user interface 23 such as a switch. When the parking brake is applied, when the hazard lamp is lit when the vehicle is stopped, when the navigation device 25 detects that the vehicle is located in the parking lot when the vehicle is stopped, or these When an arbitrary combination is satisfied, it can be determined that the passenger is about to get off at, for example.

  Next, a control method for adjusting the overhang state amount of the seat 5 will be described.

  FIG. 4 is a diagram showing a flow of control processing for adjusting the sheet overhang state amount.

  When the rider determines that the passenger is about to get on the vehicle based on a signal from the radio remote controller key 21 or the smart key 21 (boarding decision) (S100), the image is taken from the camera 15. The image of the passenger is transmitted to the ECU 13 via the image processing unit 17. Based on the received processed image, the ECU 13 estimates passenger information such as the height, weight, age, approach speed to the vehicle, degree of physical failure, and position of physical failure (S110). The ECU 13 calculates the optimum amount of extension state of the seat 5 based on the inferred passenger information, and controls the actuators 9 and 11 of the seat 5 so as to obtain this extension state amount (S120). It should be noted that the optimal overhang state quantity of the sheet 5 may be calculated by fuzzy inference, and can be calculated by any method. On the other hand, when getting off, if the ECU 13 determines that the passenger is about to get off (determination of getting off) based on the information on the user interface 23 or the like (S100), the ECU 13 is optimal based on the information on the passenger who is estimated at the time of getting on. The actuators 9 and 11 of the sheet 5 are controlled so that the amount of the extended state of the sheet 5 is reached (S120).

  When the seat 5 moves between the storage position P and the getting-on / off position Q, the ECU 13 controls the actuator 29 so that the distance between the vehicle door and the seat 5 is optimal. The seat 5 is provided with a seating sensor 31 such as a pressure sensor or a capacitance sensor for detecting the seating of the passenger and a seat belt device 33 for mounting the seat belt to the passenger. When the pressure sensor 31 detects that the passenger is seated (S130), it sends a signal to the ECU 13. When the ECU 13 receives the signal from the pressure sensor 31, the seat belt device 33 controls the seat belt so that the seat belt is adjusted to the optimum tension and belt fulcrum height for the passenger (S140). The ECU 13 adjusts the height of the belt fulcrum of the seat belt device 33 based on the height of the passenger, the position of the seat 5 (the height R of the seating surface 5a, the reclining angle β, the seat slide amount S), and the like. For example, the height of the belt fulcrum of the passenger who is tall is adjusted to be higher than the height of the belt fulcrum of the passenger who is short. At the same time, the ECU 13 controls the actuator 11 of the seat 5 based on the height, weight, etc. of the passenger and adjusts it to the optimum headrest height T, side support sandwich angle α, reclining angle β, and seat surface 5a height R. (S150). Here, the adjustment of the headrest height T, the height R of the seat surface 5a, the reclining angle β, and the side support sandwich angle α may be performed while the seat 5 is moving. It may be performed when it is detected. Note that the ECU 13 is configured to perform only the adjustment of the side support sandwich angle α when the seating of the passenger is detected from the pressure sensor 31. This makes it easier for passengers to sit on the seat 5. Based on the user identification information transmitted from the radio remote controller key 21 or the smart key 21 described above, the headrest height T, the height R of the seating surface 5a, the side support sandwich angle α, and the reclining angle β are determined in advance. It may be adjusted to a stored optimal model pattern, or may be adjusted to a state stored in advance by the user.

  Next, a specific control method for optimizing the overhang state quantity will be described.

  The ECU 13 controls the actuator 9 of the seat 5 so as to shift the boarding / exiting position Q of the seat 5 toward the vehicle rear side Q1 as the height of the passenger or the weight increases (FIG. 5). As a result, a passenger who is tall or heavy can secure a sufficient space between the seat 5 and the door, and can therefore sit and leave the seat 5 without feeling uncomfortable. Further, the ECU 13 increases the reclining angle β of the seat 5, the protruding amount W of the seat 5, and the rotation angle θ1 of the seat 5 (for example, the seat 5 as the passenger's age increases). Facing the vehicle front-rear direction, the position of Q2 shown in FIG. 6) and / or the actuators 9 and 11 so that the moving speed of the seat 5 between the storage position P and the getting-on / off position Q2 becomes slow. Control. This makes it easier for the elderly who are burdened to get on and off to sit and leave the seat, and can comfortably seat and leave the seat 5, thereby increasing safety. That is, the boarding / exiting property of the vehicle is improved. Although the moving speed is slowed down in the entire moving range of the sheet 5, the moving speed may be slowed only before and after the start and end of the movement of the sheet 5 for the purpose of shortening the moving time of the sheet 5. The actuators 9 and 11 are controlled so that the reclining operation and the seat sliding operation are completed before the operation of extending the seat 5 from the door opening 3 to the outside of the vehicle and the rotation operation of the seat at the getting-on / off position Q are completed. Also good. In this case, before the seat 5 stops at the boarding / exiting position Q, the passengers are ready to sit on the seat 5 and the convenience is improved. Further, the ECU 13 may control the seat belt device 33 so that the tension of the seat belt becomes lower as the age of the passenger gets older. Thereby, in consideration of the fragility of the bones of the elderly, the seat belt is worn, and thus the safety is further improved. On the other hand, the ECU 13 decreases the reclining angle β of the seat 5, the overhang amount W of the seat 5, and the rotation angle θ2 of the seat 5 at the getting-on / off position Q as the age of the passenger gets lower (for example, for younger people). (The position of Q3 shown in FIG. 6) and / or the actuators 9 and 11 are controlled so that the moving speed of the seat 5 between the storage position P and the getting-on / off position Q3 is increased. Thereby, the movement time of the sheet | seat 5 can be shortened between the storage position P and the boarding / alighting position Q3. Accordingly, the seat 5 can be moved to the boarding / exiting position Q3 very smoothly without making the young passengers feel irritated, and the boarding / exiting performance of the vehicle is improved. In addition, considering the fragility of the bones of the elderly, the amount of overhang state of the seat 5 can be set according to age, so the likelihood of the allowable width of the safety device can be reduced, and the safety is further improved, It is also possible to improve seat performance, reduce weight, and simplify.

  The ECU 13 calculates the approaching speed of the passenger on the vehicle based on the passenger image from the image processing unit 17, and the boarding / exiting position Q increases as the approaching speed increases (for example, when the passenger is in a hurry). The reclining angle β of the seat 5 is reduced, the overhang amount W of the seat 5 is reduced, the rotation angle θ of the seat 5 at the getting-on / off position Q is reduced, and / or between the storage position P and the getting-on / off position Q. The actuators 9 and 11 are controlled so that the moving speed of the sheet 5 increases. Note that the ECU 13 may detect the approaching speed of the passenger on the vehicle using the sonar, the radar 41, or the like. As a result, the passengers who are in a hurry are ready to sit on the seat quickly, so that the feeling of irritation is eliminated. On the other hand, the ECU 13 increases the actuator so that the moving speed of the seat 5 between the storage position P and the getting-on / off position Q becomes slower as the approach speed of the getting-on / off person decreases (for example, when the passenger gets slower). 9 and 11 are controlled. As a result, a passenger who is not in a hurry (slowly) gets ready to be seated on the seat 5 at just the right time, thus increasing the sense of security. That is, since both passengers who are in a hurry and passengers who are not in a hurry can get ready to get on at just the right time, there is a feeling of customization and the boarding / exiting ability of the vehicle is improved.

  Whether passengers are in a hurry, age, physical problems (degree of physical problems, positions of physical problems, etc.), weather (rain, snow, etc.), clothes (difficult to get on / off), etc. There is a certain correlation with speed. For example, the approach speed tends to be slow when the age is high, the degree of physical failure is high, or the clothes are difficult to get on and off. On the other hand, the approach speed tends to increase when the age is low, the weather is raining, or clothes that are easy to get on and off. That is, by adjusting the protruding state amount of the seat 5 based on the approaching speed of the passenger to the vehicle, the passenger can get on and off the vehicle in a more optimal state.

  The ECU 13 has the lower body position of the passenger's body trouble, and the higher the degree of the body trouble of the passenger, the larger the overhanging amount W of the seat 5, the greater the rotation angle θ of the seat 5 at the boarding / lowering position Q. The actuators 9 and 11 are controlled so that the reclining angle β increases and / or the moving speed of the seat 5 between the storage position P and the getting-on / off position Q decreases. Here, the fact that the degree of physical malfunction of the passenger is high means that the degree of freedom of the passenger becomes low due to the malfunction. For example, when an occupant wears a cane or is in a wheelchair, the occupant has a higher degree of physical failure and the position of the physical failure is the lower body. In addition, the ECU 13 controls the actuators 9 and 11 so that the reclining angle β is larger when the position of the passenger's physical defect is the lower body than when the passenger is in the upper body. Thereby, the optimal boarding / alighting position Q according to a body malfunctioning degree and a body malfunctioning position is ensured also with respect to the passenger who has a physical malfunction, and the boarding / alighting property of a vehicle improves. Further, by continuously varying the overhang state amount of the seat 5 in accordance with the physical trouble of the passenger, it has both functions as a general vehicle and a care vehicle, and the usefulness of the vehicle is improved.

  When the ECU 13 determines that the passenger is wearing clothes, footwear, etc. that are difficult to get on and off (for example, Japanese clothes, winter clothes such as coats, miniskirts, high heels, etc.) The seat overhang W, the rotation angle θ of the seat 5 at the loading / unloading position Q, and / or the reclining angle β of the seat 5 are larger than when it is determined that the user wears casual wear or the like (sneakers). Thus, the actuators 9 and 11 are controlled. For example, the ECU 13 may control the actuator 11 so that the reclining angle β is increased so that the seat belt avoids the belt when the passenger is wearing a kimono. In addition, the ECU 13 may control the actuator 11 so that the reclining angle β is larger when the passengers are wearing winter clothes such as coats than when they are wearing everyday clothes. As a result, passengers can sit more comfortably. Furthermore, the ECU 13 has a larger overhang amount W of the seat 5 and a rotation angle θ of the seat 5 at the getting-on / off position Q when the passengers are wearing kimonos than when wearing ordinary clothes (for example, The actuator 9 may be controlled so that the seat 5 faces the laterally outer side with respect to the vehicle longitudinal direction. As a result, passengers in Japanese clothes can easily sit on the seat 5. Further, the ECU 13 increases the protruding amount W of the seat 5 when the passenger gets on the mini skirt and wears a long skirt, and the rotation angle θ of the seat 5 at the getting-on / off position Q. The actuator 9 may be controlled so as to be small (for example, the seat 5 faces near the front of the vehicle). This improves convenience for passengers who do not want to see their feet. In other words, the overhang state amount of the seat 5 is adjusted according to the needs of the passengers, leading to an improvement in the boarding / exiting performance of the vehicle.

As described above, the overhang state amount of the seat 5 is adjusted based on the passenger information. As a result, the seat 5 is adjusted to the optimum overhang state quantity according to the passenger, and the boarding / exiting performance of the vehicle is improved.
(Second Embodiment)
In the second embodiment, a method of adjusting the overhang state amount of the seat based on weather information and time information will be described. The ECU 13 is connected to a temperature detection unit 35 such as an outside thermometer that detects the temperature outside the vehicle, and a wind speed detection unit 37 such as a Pitot tube that detects the wind speed outside the vehicle. The ECU 13 is connected to a raindrop detection unit 39 such as a raindrop sensor that detects raindrops, and the ECU 13 determines whether the weather is rain based on a signal from the raindrop sensor 39. Further, the ECU 13 is connected to a navigation device 25 that detects the current position of the vehicle. In the navigation device 25, the current position is calculated by the vehicle speed sensor and the direction sensor for the measurement of the longitude and latitude at the measurement point by the GPS geodetic satellite (or the measurement for obtaining the measurement point in more detail such as D-GPS and mapping method). By adding the movement distance of the vehicle after the determined measurement points are determined, the position of the vehicle on the map is obtained. Further, the navigation device 25 is FM multiplexed information consisting of VICS (Vehicle Information and Communication System) information, emergency information, program information, traffic information, meteorological information, etc. consisting of traffic conditions, road traffic information such as traffic regulations, and parking lot information. , G-Book information and the like can be obtained at any time.

  Other configurations are substantially the same as those of the first embodiment. In the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The ECU 13 determines that the wind speed from the Pitot tube 37 is high (when the wind speed is higher than a predetermined value, for example, a strong wind with a wind speed of 10 m / s or higher) or / and the weather is rainy by a signal from the raindrop sensor 39, and the weather is bad. The amount of overhang W of the seat 5 is smaller and the boarding / exiting position than when it is determined that the weather is fine (sunny, wind speed is a predetermined value or less, such as light wind or no wind of 1 m / s or less). The actuator 9 is controlled so that the rotation angle θ of the seat 5 at Q is reduced and / or the moving speed of the seat 5 between the storage position P and the getting-on / off position Q is increased. As a result, the movement time of the seat 5 is shortened, so that the time when the passenger gets exposed to rain or wind is shortened, and the boarding / exiting performance of the vehicle is improved. Further, the ECU 13 determines that the weather is snowy or has good weather when the weather is snowy on the road based on the weather information from the navigation device 25 or the processed image from the image processing unit 17 (however, on the road The amount of overhang W of the seat 5 is larger than the time when it is determined that there is no snow in the vehicle), the rotational angle θ of the seat 5 at the boarding / exiting position Q is large, and / or between the vehicle interior P and the boarding / exiting position Q. The actuator 9 is controlled so that the moving speed of the sheet 5 becomes slow. As a result, the passenger can sit on the seat without performing a large movement. Therefore, anxiety that the feet are unstable due to snow accumulation is reduced, and safety is improved. That is, the boarding / exiting property of the vehicle is improved. The ECU 13 determines the reclining angle β of the seat 5 based on the weather information from the navigation device 25 than when it is determined that the weather is bad such as rain or snow when the weather is fine. It is also possible to control the actuators 9 and 11 so as to reduce the pressure and to control the seat belt device 33 so that the tension of the seat belt is increased. Thus, in a state where the road surface is slippery due to rain, snow or the like, the passenger (driver) can take the posture of the brake pedal more reliably and the safety is improved. Further, when the ECU 13 determines that the temperature from the outside thermometer 35 is bad weather when the temperature is below a predetermined value (for example, when it is cold at 10 degrees or less), the temperature is just within a predetermined value (for example, 20 to 25 degrees). ) And the seat 5 between the storage position P and the boarding / lowering position Q and / or the rotation angle θ of the seat 5 at the boarding / lowering position Q is smaller. The actuator 9 is controlled so that the moving speed of 5 increases. Thereby, the movement time of the seat 5 is shortened, and the time when the passenger is exposed to the cold outside air is shortened. That is, the boarding / exiting property of the vehicle is improved.

  Further, based on the built-in clock, the ECU 13 determines that the current time is in the night time zone (for example, between 19:00 and 3 o'clock) is within the daytime zone (for example, 5:00 to 16:00). The overhang amount W of the seat 5 is increased, the rotation angle θ of the seat 5 at the loading / unloading position Q is increased, and / or the moving speed of the seat 5 between the storage position P and the loading / unloading position Q is slowed. The actuator 9 is controlled. The night time zone may be between sunset time and sunrise time, and the daytime zone may be between sunrise time and sunset time. As a result, at night when visibility is low, the passenger can sit on the seat 5 without performing a large motion. Therefore, the anxiety of passengers is reduced and safety is improved. That is, the boarding / exiting property of the vehicle is improved.

  As described above, the overhang state amount of the seat 5 is adjusted based on the weather information and the time information. As a result, the seat 5 is adjusted to the optimum overhang state amount according to the weather condition and the current time, and the boarding / exiting performance of the vehicle is improved.

(Third embodiment)
In the third embodiment, a method for adjusting the overhang state amount of the sheet based on the position information will be described. The configuration of the third embodiment is substantially the same as that of the second embodiment. In the third embodiment, the same parts as those in the first and second embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  When the ECU 13 determines that the current position of the vehicle from the navigation device 25 is in the danger area, the ECU 13 is smaller than the overhang amount W of the seat 5 than the safety area, and smaller than the rotation angle θ of the seat 5 at the getting-on / off position Q. And / or the actuator 9 is controlled so as to increase the moving speed of the seat 5 between the storage position P and the getting-on / off position Q. Thereby, the movement time of the seat 5 is shortened, and the passenger's sense of crisis is reduced. The above dangerous areas are, for example, areas with high traffic volume (areas where the traffic volume is greater than or equal to a predetermined value), areas with a high number of crimes (areas where the number of crimes is greater than a predetermined value), areas with a high number of traffic accidents (traffic accidents) This applies to areas where the number of cases is equal to or greater than the predetermined value). In addition, the above safe areas include, for example, areas with low traffic volume (traffic volume is below a predetermined value), safe areas with low crime count (number of crimes is below a predetermined value), safe areas with low traffic accident count (traffic accidents) The number of cases is equal to or less than a predetermined value). These areas are stored in the navigation device 25 in advance.

  Further, when the ECU 13 determines that the current position of the vehicle from the navigation device 25 is on a main trunk road with a high traffic volume (the traffic volume is greater than a predetermined value, for example, an expressway, a national road, a prefectural road, etc.) The actuator 9 is controlled so that the moving speed of the seat 5 between the storage position P and the getting-on / off position Q is increased. Note that the safe area refers to an area with a small traffic volume such as a general road (the traffic volume is a predetermined value or less, such as a municipal road, a private road, etc.). Thereby, since the passenger can get on and off in a short time, safety is improved. Further, when the ECU 13 determines that the current position of the vehicle from the navigation device 25 is in the parking lot, the actuator 9 is set so that the moving speed of the seat 5 between the storage position P and the getting-on / off position Q is slower than the standard speed. To control. The standard speed is the protruding speed of the seat 5 in a state where there are no obstacles such as curbs, bicycles, other people, other vehicles, and buildings around the vehicle (no obstacles within a predetermined distance from the vehicle). . If there are no obstacles around the vehicle, the seat 5 is projected at a preset speed such as a preset speed at the initial setting of the dealer or a preset speed set by the user according to the user's preference. Alternatively, the seat 5 may be extended by the camera 15 or the like at a speed set based on the physical information of the passenger. Thereby, safety is ensured in the operation in a narrow space such as a parking lot.

  As described above, the overhang state amount of the sheet 5 is adjusted based on the position information. As a result, the seat 5 is adjusted to the optimum overhang state amount according to the current position of the vehicle, and the boarding / exiting property of the vehicle is improved.

  The best mode for carrying out the present invention has been described with reference to the embodiments. However, the present invention is not limited to these embodiments, and has been described above without departing from the gist of the present invention. Various modifications and substitutions can be made to the embodiments.

  For example, in the above-described embodiment, the present invention is applied to the front left seat, but can be applied to the front right seat and the rear seat. That is, it can be applied to any seat in the vehicle interior.

  Further, in the above embodiment, when the ECU 13 detects an obstacle within a predetermined distance by the sonar 41 or the like, the moving speed of the seat 5 between the storage position P and the getting-on / off position Q is reduced from the standard speed. You may move it. The standard speed is the protruding speed of the seat 5 in a state where there are no obstacles such as curbs, bicycles, other people, other vehicles, and buildings around the vehicle (no obstacles within a predetermined distance from the vehicle). . If there are no obstacles around the vehicle, the seat 5 is projected at a preset speed such as a preset speed at the initial setting of the dealer or a preset speed set by the user according to the user's preference. Alternatively, the seat 5 may be extended by the camera 15 or the like at a speed set based on the physical information of the passenger. This reduces the moving speed of the sheet 5 when there is a protrusion such as a curbstone within a predetermined distance (for example, in the vicinity of the sheet 5). Therefore, a passenger's sense of security can be improved.

  The present invention can be used for a vehicle seat control device. The appearance, weight, size, running performance, etc. of the vehicle to be mounted are not limited.
