Embodiments to which the present invention is applied will be described below with reference to the drawings.
[1. First Embodiment]
[1-1. Constitution]
A vehicle-mounted display device 1 shown in FIG. 1 is a device that is mounted on a vehicle and performs display related to the behavior of the vehicle. The in-vehicle display device 1 includes an input unit 10, a display execution unit 30, and a control unit 50.

The input unit 10 includes a target detection unit 11, a vehicle behavior detection unit 12, and an information input unit 13.
The target detection unit 11 detects a predetermined detection target within a predetermined detection range around a vehicle (hereinafter referred to as the host vehicle) on which the in-vehicle display device 1 is mounted. Below, the target detection part 11 demonstrates the example which detects a pedestrian as a detection target within the predetermined detection range including the front of the own vehicle at least.

  Specifically, the object detection unit 11 includes two wide-angle cameras (fisheye cameras) that can capture an image with an angle of view of approximately 180 degrees as an example. These wide-angle cameras are installed on the front side and the rear side of the host vehicle so that an image within the detection range can be taken with a range of approximately 360 degrees centered on the host vehicle. The image is repeatedly taken in front and behind. The target detection unit 11 outputs imaging data that is data representing a captured image captured by these cameras to the control unit 50.

  Note that the detection range by the target detection unit 11 may be arbitrarily determined, and the number of wide-angle cameras may be increased or decreased according to the detection range and detection target, or a camera other than the wide-angle camera may be used. Further, a radar device may be used to detect a detection target in the detection range.

  The vehicle behavior detection unit 12 is for detecting the behavior of the host vehicle. The behavior of the host vehicle refers to a state related to the traveling of the host vehicle, such as stopping, starting, and continuing traveling (hereinafter referred to as traveling). Note that the behavior of the host vehicle detected by the vehicle behavior detector 12 is not limited to stopping, starting, and traveling, and may be any behavior of the host vehicle such as a right turn and a left turn. However, in the following description, behavior such as stopping, starting, and running will be described as an example of the behavior of the host vehicle.

  The vehicle behavior detection unit 12 includes at least a vehicle speed sensor in order to detect the behavior of the host vehicle such as stopping, starting, and running. The vehicle speed sensor generates a vehicle speed signal according to the rotation of the axle, detects the vehicle speed of the host vehicle based on the vehicle speed signal, and outputs the detected vehicle speed to the control unit 50.

  The information input unit 13 causes the occupant of the host vehicle to input a schedule (schedule information) related to the behavior of the host vehicle, and outputs input information based on the input to the control unit 50. The schedule related to the behavior of the host vehicle here is scheduled next to the current behavior, such as stopping if the host vehicle is running, starting if the host vehicle is stopped, etc. Refers to the behavior.

  In other words, the schedule related to the behavior of the host vehicle is information indicating how the occupant of the host vehicle intends to operate the host vehicle, that is, information indicating a will display regarding the driving operation by the occupant of the host vehicle. It can be said. In the following, the schedule related to the behavior of the host vehicle is simply referred to as the schedule of the host vehicle.

  As an example, the information input unit 13 includes a touch panel display (not shown). On the touch panel display, for example, buttons indicating the schedule of the host vehicle, such as “stop” and “start”, are displayed.

  Here, for example, when a “stop” button is selected by a driver who is a passenger of the host vehicle, the information input unit 13 controls input information indicating that “stop” has been selected by using this as an input. Output to the unit 50. On the other hand, when the “start” button is selected by the driver who is an occupant of the own vehicle, the information input unit 13 receives this as input and the input information indicating that “start” is selected to the control unit 50. Output.

  The display execution unit 30 displays the behavior mark above the road surface based on the display data input from the control unit 50. The behavior mark refers to a mark representing the future behavior of the host vehicle (for example, after a few seconds) such as stopping, starting, or running. The display execution unit 30 displays a behavior mark at a position that can be recognized by the detection target from the detection range of the target detection unit 11.

  The detection range of the detection target by the vehicle behavior detection unit 12 is a predetermined range in the vicinity of the host vehicle. The position that can be recognized by the detection target such as a pedestrian from the detection range is a position that is above the road surface, and a pedestrian that is present in the detection range can see the behavioral mark. Determined based on.

  In this embodiment, the display execution part 30 displays a behavior mark on the vehicle body surface of the own vehicle. Specifically, the display execution unit 30 includes an LED unit 31 as illustrated in FIG. 2A as an example, and the LED unit 31 includes the host vehicle 90 as illustrated in FIG. 3A as an example. Are installed on the wheel 92 of each wheel 91. As shown in FIG. 3B as an example, the LED unit 31 includes LED units 31a to 31i in which a plurality of LEDs (Light Emitting Diodes) are arranged to form a circle. LED is arrange | positioned so that the LED part 31a may become larger circular shape than the surrounding LED part 31b-LED part 31i.

  In this embodiment, the LED part 31a is arrange | positioned in the center part, and the LED part 31b-LED part 31i is arrange | positioned at equal intervals on the circumference | surroundings around the LED part 31a and centering on the LED part 31a. . As an example of the LEDs arranged in the LED units 31a to 31i, red LEDs are used.

  The LED unit 31a to the LED unit 31i turn on and off the LEDs according to display data input from the control unit 50, respectively. Thereby, the display of the behavior mark indicating the behavior of the host vehicle such as stop, start, and running is realized. An example of the behavior mark is shown in FIG.

  Specifically, the behavior mark indicating the stop may be a mark that lights all of the LED units 31a to 31i as shown in FIG. Further, as shown in FIG. 4B, the behavior mark indicating that the host vehicle is to be started is such that the LED unit 31a is turned off and the LED unit 31b to the LED unit 31i are rotated when the host vehicle is running. The circles are turned on and off sequentially in the expected direction (counterclockwise in FIG. 4B), and the surrounding LED portions 31b to 31i are turned on (counterclockwise in FIG. 4B). It may be a mark to be shown as drawn. Further, the behavior mark indicating that the vehicle is traveling may be a mark that blinks only the central LED unit 31a, as shown in FIG.

  The control unit 50 includes a known microcomputer having a CPU 51, a ROM 52, a RAM 53, and the like. The control unit 50 executes processing for realizing various functions based on a program recorded in the ROM 52. As an example, the control unit 50 executes a display process described later.

[1-2. processing]
Next, display processing executed by the control unit 50 (CPU 51) will be described with reference to the flowchart of FIG. The process shown in FIG. 5 displays “stop” when the host vehicle is stopped, “start” when the host vehicle is about to start, and a behavior mark indicating “running” when the host vehicle is running. This is a process to be displayed on the execution unit 30. Note that the process shown in FIG. 5 is repeatedly executed while the ACC switch is on.

First, in S (step) 100, the vehicle speed of the host vehicle is acquired from the vehicle behavior detection unit 12.
In S110, it is determined whether or not the host vehicle is stopped. Specifically, when the vehicle speed acquired from the vehicle behavior detection unit 12 is less than a predetermined stop threshold, it is determined that the host vehicle is stopped. The stop threshold value is set to a vehicle speed indicating that the host vehicle is stopped. The stop threshold is set to, for example, 0 km / hour (0 [km / hour]). If it is determined that the host vehicle has not stopped, the process proceeds to S100. On the other hand, if it is determined that the host vehicle is stopped, the process proceeds to S120.

In S <b> 120, imaging data is acquired from the target detection unit 11.
In S130, it is determined whether a detection target is detected within a predetermined detection range. Specifically, by performing image processing based on the imaging data acquired from the target detection unit 11, a pedestrian that is a detection target is detected within a detection range that is experimentally predetermined as described above. In this case, it is determined that the detection target is detected. If no pedestrian is detected, the process proceeds to S100. On the other hand, if a pedestrian is detected, the process proceeds to S140.

  In S140, a behavior mark indicating a stop is displayed. Specifically, as illustrated in FIG. 4A, an instruction to turn on all of the LED units 31a to 31i is generated, and the instruction is output to the display execution unit 30 as display data.

In S150, the input information generated based on the operation by the occupant of the host vehicle is acquired from the information input unit 13 as schedule information representing a schedule related to the behavior of the host vehicle.
In S160, it is determined whether or not the schedule information acquired in S150 represents transmission. Specifically, when the input information acquired in S150 is information representing a start, in other words, when the start is selected by the information input unit 13 (touch panel display) by the vehicle occupant, It is determined that the information represents transmission. Here, if the schedule information does not represent a start, the process proceeds to S110. As a result, the behavior mark indicating the stop is continuously displayed until the information input unit 13 selects the start button by the vehicle occupant (S160; YES). On the other hand, if the schedule information represents a start, the process proceeds to S170.

  In S170, a behavior mark indicating the start is displayed. Specifically, as shown in FIG. 4B, the LED unit 31a is turned off, and the LED unit 31b to the LED unit 31i are sequentially turned on and off in a direction in which tire rotation is expected during traveling. And outputs the instruction to the display execution unit 30 as display data.

  In S180, it is determined whether or not the host vehicle has actually started. Specifically, the vehicle speed of the host vehicle is acquired from the vehicle behavior detector 12, and it is determined that the host vehicle has started when the acquired vehicle speed is greater than or equal to a predetermined start threshold. The start threshold is a predetermined value larger than the stop threshold, for example, about several kilometers per hour. If it is determined that the host vehicle has not started, the process proceeds to S170. On the other hand, if it is determined that the host vehicle has started, the process proceeds to S190.

  In S190, a behavior mark indicating movement is displayed. Specifically, as shown in FIG. 4C, an instruction to blink only the central LED unit 31a is generated, and the instruction is output to the display execution unit 30 as display data. Then, the process proceeds to S100, and a series of processes from S100 to S190 is repeated.

[1-3. effect]
According to the first embodiment described in detail above, the following effects can be obtained.
[1A] The control unit 50 acquires schedule information indicating a schedule related to the behavior of the host vehicle (S150), and a pedestrian as a detection target is detected within the detection range of the target detection unit 11 (S130; YES). In addition, based on the acquired schedule information, display data for displaying a behavior mark that is a mark representing the behavior of the host vehicle is generated (S140, S170, S190). According to this, the behavior mark is displayed above the road surface. For this reason, it is possible to display the behavior mark so that it can be easily recognized by a detection target such as a pedestrian, compared to the conventional technique for displaying on the road surface.

  [1B] Display based on the schedule information is performed at a position above the road surface and recognizable by the detection target from the detection range. According to this, it is possible to make the detection target such as a pedestrian recognize the display of the behavior mark more reliably.

  [1C] The display execution unit 30 displays a behavior mark on the surface of the vehicle body of the host vehicle. According to this, it becomes possible to make a detection target such as a pedestrian recognize a behavior mark from a distance farther than the conventional technique for displaying on a road surface.

  [1D] When the vehicle behavior detection unit 12 detects that the behavior of the host vehicle is stopped, the control unit 50 acquires schedule information from the information input unit 13 (S150). If it represents that the vehicle is scheduled to start (S160; YES), display data for displaying a behavior mark indicating that the vehicle is scheduled to start is generated (S170).

  According to this, it is possible to make a pedestrian who is a detection target existing within the detection range recognize that the stopped own vehicle has a start plan. In other words, it is possible to make a pedestrian who is a detection target existing in the detection range recognize that the vicinity of the host vehicle can be in a dangerous state.

  [1E] The control unit 50 causes the display execution unit 30 to display a behavior mark indicating that the vehicle is scheduled to start based on the display data, and then until the vehicle behavior detection unit 12 detects the start of the host vehicle (S180; YES), display based on the display data is continued. According to this, since the behavior mark indicating that the vehicle is scheduled to start is displayed until the vehicle actually starts, the surroundings of the vehicle become a dangerous state for the pedestrian who is the detection target within the detection range. You can continue to recognize what you get.

  [1F] The control unit 50 generates display data for displaying a behavior mark indicating that the host vehicle is scheduled to start, and then the vehicle behavior detection unit 12 detects the start of the host vehicle (S170; YES). Then, display data for displaying a behavior mark indicating that the host vehicle is traveling is generated (S190).

  According to this, after the start of the host vehicle, the behavior mark indicating that the host vehicle is traveling is displayed, so that the host vehicle is traveling, in other words, the behavior marker indicating that the host vehicle is scheduled to start. It is possible to make a detection target such as a pedestrian existing in the detection range recognize that the vicinity of the host vehicle is more dangerous than when the is displayed.

  [1G] The control unit 50 acquires, as schedule information, input information generated based on an operation by an occupant of the host vehicle (S150). For example, the schedule of the behavior of the host vehicle, such as starting, may be determined based on input from a passenger of the host vehicle, for example, a driver. According to this, the intention of the driving operation by the passenger of the own vehicle can be reflected in the behavior mark.

  In the first embodiment, the target detection unit 11 corresponds to an example of the target detection unit, the vehicle behavior detection unit 12 corresponds to an example of the behavior detection unit, and the display execution unit 30 (LED unit 31) displays the display. This corresponds to an example of an execution unit, and the control unit 50 corresponds to an example of a display generation unit.

[2. Second Embodiment]
[2-1. Constitution]
Since the basic configuration of the second embodiment is the same as that of the first embodiment, the description of the common configuration will be omitted, and the description will focus on the differences.

  In the first embodiment described above, as shown in FIG. 2A, the behavior indicator is displayed on the vehicle body surface of the host vehicle on the display execution unit 30 (30a). On the other hand, as shown in FIG. 2B, the second embodiment differs from the first embodiment in that the behavior indicator is displayed in the air in front of the host vehicle on the display execution unit 30 (30b). .

  As an example, the display execution part 30b of this embodiment is provided with the plasma irradiation apparatus 32 which irradiates plasma in the air ahead of the own vehicle. As an example, the plasma irradiation device 32 is installed on the front side in the traveling direction of the host vehicle 90 as shown in FIG. The plasma irradiation device 32 displays a behavior mark by irradiating plasma in the air ahead of the host vehicle in accordance with display data from the control unit 50.

  Since the plasma irradiation device 32 is accompanied by a plasma generation sound at the time of display, it can be said that the plasma irradiation device 32 is a device that generates a sound in accordance with the display of the behavior mark. Since details of the plasma irradiation device 32 are well known, description thereof is omitted here (see, for example, “Development and Advanced Use of Atmospheric Pressure Plasma Device”, Toshitoshi Okino (Tokyo Institute of Technology)).

[2-2. processing]
In the present embodiment, the control unit 50 performs the same processing as in the first embodiment except for S140, S170, and S190 in the flowchart shown in FIG. In the present embodiment, in S140, S170, and S190, instructions for causing the plasma irradiation device 32 to display behavior marks indicating stop, start, and running are displayed as display data to the display execution unit 30b (plasma irradiation device 32). Output.

[2-3. effect]
According to the second embodiment described in detail above, in addition to the effects [1A] to [1B] and [1D] to [1G] of the first embodiment described above, the following effects are obtained.

  [2A] The display execution unit 30b displays a behavior mark in the air in front of the host vehicle. According to this, it becomes possible to make the detection target recognize the behavior mark from a distance farther than the conventional technique for displaying on the road surface. In particular, for a detection target such as a pedestrian, for example, by displaying the behavior mark near the height of the pedestrian's line of sight in front of the host vehicle, the behavior mark can be easily recognized.

  [2B] The display execution unit 30b generates a sound with the display of the behavior mark. According to this, for example, a pedestrian who is looking away, such as walking while looking at a multifunctional mobile phone such as a smartphone, can recognize the presence of the display of the behavior mark by sound.

In the second embodiment, the display execution unit 30b (plasma irradiation device 32) corresponds to an example of a display execution unit.
[3. Other Embodiments]
As mentioned above, although embodiment of this invention was described, it cannot be overemphasized that this invention can take a various form, without being limited to the said embodiment.

  [3A] In the above embodiment, the control unit 50 acquires the input information from the information input unit 13 as the schedule information, but the method for acquiring the schedule information is not limited to this. Based on the current behavior of the host vehicle detected by the vehicle behavior detection unit 12, the control unit 50 may generate and acquire schedule information representing the behavior of the future host vehicle (for example, after a few seconds). Good.

  For example, the control unit 50 first performs a process of measuring and outputting an elapsed time after the host vehicle stops, triggered by the fact that the stop of the host vehicle is detected by the vehicle behavior detection unit 12. There may be.

  In this case, the control unit 50 acquires the above-described elapsed time (S142) as in the flowchart shown in FIG. 7 instead of the flowchart shown in FIG. 5 and sets the elapsed time in advance, for example, several tens (seconds). When the time exceeds the allowable time (S144; YES), start information may be generated (S146). The start information is information indicating that the host vehicle is scheduled to start.

  For example, when the subject vehicle is a vehicle to which automatic driving that automatically performs at least a part of steering is applied, the subject detection unit 11 always detects the detection target in front of the subject vehicle after the subject vehicle stops. (For example, in the case where a pedestrian trying to cross the front of the host vehicle is always detected), a situation may occur in which the host vehicle cannot be started even if the user wants to start. In such a case, when the elapsed time increases, the driver of the host vehicle is required to start the host vehicle.

  For this reason, when the elapsed time increases and exceeds the allowable time, start information indicating that the host vehicle is scheduled to start may be generated. The permissible time is preferably set to a time that allows the driver of the host vehicle to permit the stop of the host vehicle and that does not prevent the pedestrian from crossing.

  Then, when the vehicle behavior detection unit 12 detects that the behavior of the host vehicle is stopped, the control unit 50 acquires the above-described start information as schedule information (S150), and the schedule information is the start of the host vehicle. When it represents that there is a plan (S160; YES), display data for displaying a behavior mark indicating that the host vehicle is scheduled to start may be generated (S170).

According to this, it is possible to automatically determine the schedule of the behavior of the host vehicle to start, not the operation by the vehicle occupant, that is, manual operation.
In addition, for example, when automatic driving is applied to the host vehicle, it is indicated that the vehicle is scheduled to start especially when the host vehicle is stopped for a predetermined allowable time or more as described above. The intention display about a behavior can be performed with respect to a pedestrian. Thus, a smooth traffic flow can be realized for both the vehicle and the pedestrian.

  In this case, the control unit 50 corresponds to an example of an elapsed time acquisition unit and a start schedule information generation unit. Further, S142 corresponds to an example of processing as an elapsed time acquisition unit, and S146 corresponds to an example of processing as a start schedule information generation unit.

  [3B] In the above embodiment, the behavior mark indicating the behavior of the host vehicle 90 such as stopping, starting, and running is represented by a mark formed by combining a plurality of circles as shown in FIG. It is not a thing. The behavior mark may be, for example, a straight arrow as shown in FIG. 8A provided on the side of the vehicle body of the host vehicle 90, or a curved shape as shown in FIG. 8B. May be an arrow. Further, the behavior mark may be a triangular mark as shown in FIG. 8C provided at the upper part of the hood of the vehicle body of the host vehicle 90. In other words, the behavior mark may be in any form as long as it is displayed in a manner in which a difference can be discriminated for each content of behavior of the host vehicle 90.

  [3C] In the first embodiment, red LEDs are used as the LEDs arranged in the LED units 31a to 31i. However, the present invention is not limited to this, and LEDs of any color may be used. Moreover, the LED unit 31a to the LED unit 31i may be configured by arranging a plurality of LEDs in a circular shape as described above, or alternatively, may be configured as follows. That is, for example, one or a plurality of LEDs are arranged at positions corresponding to the centers of the LED units 31a to 31i, and circular light having the same size as the LED units 31a to 31i appears to be lit. Thus, you may comprise LED part a-LED part 31i by covering this LED with the cover formed in the circle shape with the material which permeate | transmits light.

  [3D] In the first embodiment, the display execution unit 30a includes an LED for displaying a behavior mark on the surface of the vehicle body. However, the configuration of the display execution unit 30a is not limited to this. Absent. The display execution unit 30a may include, for example, a well-known LCD display or projector instead of the LED in order to display a behavior mark on the vehicle body surface of the host vehicle.

  [3E] In the second embodiment, the display execution unit 30b includes the plasma irradiation device to display the behavior mark in the air in front of the host vehicle. However, the configuration of the display execution unit 30b is limited to this. It is not a thing. Instead of the plasma irradiation device, the display execution unit 30b is, for example, a well-known fog display (see “Multi-viewpoint fog display”, Asuka Yagi et al. (Osaka University) Information Processing Society of Japan Interaction 2011 Proceedings 1INH-5) or Also, a visible image forming apparatus (see JP 2003-233339 A) may be provided.

  [3F] In the above-described embodiment, the example in which the behavior mark is displayed for the behavior of the host vehicle such as stop, start, and running is described. However, the behavior of the host vehicle in which the behavior mark is displayed is not limited thereto. . For example, a behavior mark may be displayed for the behavior of an arbitrary host vehicle such as a right turn and a left turn.

  In this case, the vehicle behavior detection unit 12 is not limited to the vehicle speed sensor as in the above-described embodiment, and includes, for example, a steering angle sensor for detecting the behavior of the host vehicle such as a right turn and a left turn of the host vehicle. May be. Further, the information input unit 13 is not limited to the touch panel display as in the above-described embodiment (first embodiment), and for example, a direction indicator for detecting a schedule of the behavior of the host vehicle such as a right turn and a left turn of the host vehicle. May be provided.

  Further, the button indicating the schedule of the host vehicle displayed on the touch panel display in the information input unit 13 is not limited to “stop” and “start” as in the above-described embodiment (first embodiment). Buttons indicating the schedule of an arbitrary host vehicle such as “right turn” and “left turn” may be displayed.

  Moreover, the control part 50 acquires the input information from the information input part 13 showing the schedule of the behavior of the own vehicle, such as the right turn and the left turn of the own vehicle, as schedule information, as in the above-described embodiment (first embodiment). Display data for displaying the behavior mark may be generated, and the behavior mark may be displayed on the LED unit 31 based on the display data. In this case, for example, an LED display unit in which LEDs are arranged in a predetermined shape is provided at the right end and the left end of the host vehicle, and the LED display unit at the right end of the host vehicle is turned on when displaying a “right turn” behavior mark. The display data may be generated such that when the “left turn” behavior mark is displayed, the LED display at the left end of the host vehicle is turned on.

  [3G] In the above-described embodiment, the example in which the behavior mark is displayed above the road surface with respect to the behavior of the host vehicle such as stop, start, and running is described. May be displayed. In this case, in the in-vehicle display device, the display execution unit 30 includes a drawing device on the road surface, and the control unit 50 outputs a command for displaying the behavior mark on the drawing device as display data. There may be.

  [3H] In the above embodiment, an example has been described in which the object detection unit 11 detects a pedestrian as a detection target and displays a behavior mark so that the pedestrian can easily recognize the pedestrian, but the detection target is not limited thereto. Any other object may be used. For example, the detection target may be another vehicle. In this case, it is desirable that the behavior mark be displayed at a position (height) that can be easily seen by a driver or other passenger in another vehicle within a predetermined detection range.

  For example, the behavior mark by the LED unit 31 is displayed on the rear end, the upper part of the front end, the side mirror, etc. in the own vehicle, or the behavior mark by the plasma irradiation device 32 is displayed not only in front of the own vehicle but also in the rear or side. You may go. When the detection target is another vehicle, the detection range in which the other vehicle is to be detected and the position of the behavior mark that should be recognized by the other vehicle (occupant) may be determined based on experiments.

  [3I] The functions of one component in the embodiment may be distributed as a plurality of components, or the functions of a plurality of components may be integrated into one component. Further, at least a part of the configuration of the above embodiment may be replaced with a known configuration having the same function. Moreover, you may abbreviate | omit a part of structure of the said embodiment as long as a subject can be solved.
