Description

Seat regulation and control method for vehicle, computer program product, control system and vehicle
Technical Field
The present invention relates to the field of vehicle seats, in particular to a seat control method for a vehicle, a computer program product, a control system and a vehicle with the control system.
Background
Currently, a rear airbag for a vehicle is not highly popular due to its high cost, and the impact on a rear passenger is only limitedly reduced even when the vehicle collides with the conventional rear airbag. Thus, currently in a vehicle crash event, rear occupants tend to suffer more severe head impact injuries due to lack of protection of airbags equipped in the front row, which is also highlighted in almost all current car crash tests by rear dummies.
Thus, there is a need to provide more adequate protection for rear occupants in a vehicle collision event.
Disclosure of Invention
It is an object of the present invention to provide a seat control method, a computer program product, a control system for a vehicle and a vehicle with such a control system, which aim at adjusting at least a front seat before a collision in order to give a rear passenger a sufficiently large safety space before or at least during the collision for the purpose of protecting the rear passenger, which are able to avoid the collision of the rear passenger with a front object using the existing vehicle seat functions, compared to a rear airbag, in order to economically and efficiently provide protection for the rear passenger.
According to a first aspect of the present invention, there is provided a seat conditioning method for a vehicle, the method comprising at least the steps of:
acquiring a collision warning signal of a vehicle, wherein the collision warning signal indicates that the vehicle is about to collide with a front object or is colliding with the front object;
acquiring a front-row seat state of a front-row seat and a rear-row seat state of an adjacent rear-row seat behind the front-row seat in response to a collision warning signal; and
in the case where the front seat state satisfies the first predetermined condition and the rear seat state satisfies the second predetermined condition, the front seat is adjusted according to the front seat state so that the front seat is in a position in which a space between the front seat and the rear seat is increased and/or an adjustment state in which the space between the front seat and the rear seat is allowed to be increased before and/or during a collision.
With the method according to the first aspect of the invention, it is possible to adjust the seats for various seating situations by determining whether and how to adjust the front seats according to the states of the front and rear seats before a collision occurs, thereby providing a larger safety space for the seated rear passengers before the collision occurs or at least allowing a larger safety space for the rear passengers during the collision to be provided, avoiding or at least minimizing the collision of the rear passengers with a front object at the time of the vehicle collision, and maximizing the protection for the rear passengers.
In an exemplary embodiment, the first predetermined condition includes the front seat being in a position allowing the space to be enlarged relative to the rear seat; and/or the second predetermined condition comprises the rear seat being in an occupant occupancy state. Therefore, when the front-row seat is in a position state which does not allow the enlargement of the rear-row space or when no passenger sits on the rear-row seat, the regulation and control of the enlarged rear-row space of the seat are not needed.
In one exemplary embodiment, the front seat states include an occupant occupancy state and a non-occupant occupancy state of the front seat. Therefore, the front seat can be regulated and controlled in different modes corresponding to the passenger occupying state and the non-passenger occupying state of the front seat respectively, and larger space is provided for the rear passengers as far as possible in each state.
In one exemplary embodiment, the front seat state is determined to satisfy a first predetermined condition if the front seat is in a non-occupant occupying state, the space being allowed to increase by at least allowing the front seat as a whole to move forward a first predetermined distance and/or the seatback of the front seat to rotate forward to a first predetermined angle. In a preferred exemplary embodiment, the space is increased by moving the front seat as a whole to the forwardmost allowable position and/or rotating the seatback of the front seat forward to the maximum allowable angle. Thus, in the case where no one is seated in the front seat, it is possible to provide the maximum safety space for the rear occupant before the impact occurs.
In one exemplary embodiment, if the front seat is in the occupant occupying state, an allowable adjustment parameter of the front seat is calculated and it is determined whether the front seat state satisfies a first predetermined condition based on the calculated allowable adjustment parameter, and when it is determined that the front seat state satisfies the first predetermined condition, the front seat is adjusted based on the allowable adjustment parameter so that the space is increased. In a preferred exemplary embodiment, the space is allowed to increase by at least allowing the front seat as a whole to move forward a second predetermined distance and/or the seatback of the front seat to rotate forward to a second predetermined angle; and/or the adjustment enabling parameter is determined based on the current position of the front seat and/or the physical parameters of the occupant. Thus, even if the front seat is in the occupant occupying state, the maximum safety space allowed can be provided for the rear occupant before the occurrence of the collision or at least during the occurrence of the collision as much as possible.
In an exemplary embodiment, the physical parameters include height and/or weight.
In one exemplary embodiment, the front seat is a front passenger seat of the vehicle.
According to a second aspect of the invention, a computer program product, in particular a computer readable program carrier, is provided, comprising or having stored computer program instructions which, when executed by a processor, are capable of at least assisting in performing the method according to the first aspect of the invention.
According to a third aspect of the present invention, there is provided a control system for a vehicle, comprising:
a controller comprising a memory and a processor, the memory storing computer program instructions which, when executed by the processor, are capable of at least assisting in performing the method according to the first aspect of the invention.
In one exemplary embodiment, the control system further comprises: the seat detection device comprises a front-row seat detection device used for detecting the state of a front-row seat and a rear-row seat detection device used for detecting the state of a rear-row seat.
In one exemplary embodiment, the front seat detecting device includes: a seat belt sensor; and/or an occupant weight sensor that detects the weight of an occupant; and/or a ride height sensor for detecting a ride height of the occupant; and/or a seat camera.
In one exemplary embodiment, the control system further comprises a seat adjustment actuator configured to include: a seat movement actuator configured to allow the seat to be moved back and forth as a whole; and a seatback rotation actuator configured to allow a seatback of the seat to rotate back and forth.
According to a fourth aspect of the present invention, there is provided a vehicle comprising:
the control system according to the third aspect of the invention; and
collision detection and warning device, it includes at least:
the front camera and/or the radar are/is used for detecting the information of the front object;
a vehicle speed sensor that acquires a speed of the vehicle; and
and the processing unit generates a collision warning signal and sends the collision warning signal to the controller when the processing unit judges that the vehicle collides with the front object based on the distance between the front camera and the front object detected by the radar and the speed of the vehicle acquired by the vehicle speed sensor.

Detailed Description
In order to make the technical problems, technical solutions and advantageous effects of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and exemplary embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention.
Fig. 1 schematically illustrates a seat adjusting method for a vehicle according to an exemplary embodiment of the present invention. Fig. 3 schematically illustrates an adjustable vehicle seat that may be used as a front row seat 300. As shown in fig. 3, the front seat includes a seat back 301, a seat cushion 302, an occupant weight sensor 303 as an exemplary part of a front seat detecting device 20 described later, a front seat movement actuator 304 and a front seat back rotation actuator 305 as exemplary parts of a seat regulation actuator 40 described later, and a guide rail 306.
As shown in fig. 1, a seat adjusting method for a vehicle according to an exemplary embodiment of the present invention includes at least the following steps S1 to S3:
s1: acquiring a collision warning signal of the vehicle, wherein the collision warning signal indicates that the vehicle is about to collide with a front object or is colliding with the front object;
s2: acquiring a front seat state of a front seat 300 and a rear seat state of an adjacent rear seat located behind the front seat 300 in response to a collision warning signal; and
s3: each seat is adjusted before the collision occurs according to the state of each seat acquired in step S2 so that the front seat 300 and the rear seat are in a state that allows at least the space between the front seat 300 and the rear seat to be increased before and/or during the collision.
In step S1, the collision warning signal is generated based on the detection of the front road by the collision detection and warning device of the vehicle. The collision detection and warning device is provided with a detection device such as a front camera and/or a radar, for example, to detect a forward traveling condition and generates a collision warning signal to notify or warn a driver or a vehicle occupant or a vehicle control system when it is determined that the vehicle is about to collide with a forward object or has collided with based on the detection result of the detection device.
In step S2, upon receipt of the collision warning signal, the seat states of the respective vehicle seats in the vehicle compartment are detected and acquired. Specifically, the front seat state of each front seat 300 and the rear seat state of the adjacent rear seat positioned behind each front seat are detected. The front seat state includes, but is not limited to, an occupant occupying state and a non-occupant occupying state of the front seat 300, which are states in which an occupant is seated and no occupant is seated on the corresponding seat, respectively, and a current position of the front seat 300 including, for example, a position within a movable range of the front seat 300 in the front-rear direction along the guide rail 306 and a seatback posture of the seatback 305 including, for example, a posture of an angle of the seatback 301 with respect to the seat cushion 302, a degree of extension and contraction of the headrest, and the like. Similarly, the rear seat state also includes, but is not limited to, an occupant occupied state and a non-occupant occupied state of the rear seat, as well as the current position and seat back attitude of the rear seat. Preferably, upon detecting that the seat is in the occupant occupying state, also physical parameters of the respective occupant are acquired, such as height/sitting height and/or weight and/or posture, etc.
In step S3, in one embodiment, the front seat 300 is adjusted in accordance with the front seat state acquired in step S2 such that the front seat 300 is in a state that allows at least a space between the front seat and the rear seat to be increased before and/or during the collision.
In one embodiment, in the case where the front seat state satisfies the first predetermined condition and the rear seat state satisfies the second predetermined condition, the front seat is adjusted in accordance with the front seat state to a state in which the front seat is in a state in which a space between the front seat and the rear seat is increased and/or an adjustment state in which the space between the front seat and the rear seat is allowed to be increased before and/or during a collision. Specifically, the modes of adjustment for the front seats include, but are not limited to: before a collision occurs, bringing the front seat into a position in which a space between the front seat and the rear seat is increased; when a collision is occurring, the front seat is regulated to a position in which a space between the front seat and the rear seat is increased during the occurrence of the collision; before a collision occurs, the front seat is regulated to be in a regulation state which allows the position of the front seat to be changed so as to increase the space between the front seat and the rear seat; and adjusting the front seat to be in an adjustment state that allows the posture thereof to be changed so that the space between the front seat and the rear seat is increased, when a collision is occurring. Preferably, the front seat can be adjusted and controlled in a suitable combination of one or more of the above modes according to actual needs. The above-mentioned "allowing the change of the posture of the front seat" includes, but is not limited to, the case where the front seat passively changes the posture of the front seat, for example, due to a force applied from behind, and/or changes the posture of the front seat with a predetermined value as the collision progresses, for example, an allowable adjustment parameter set or calculated in accordance with the posture of the front seat before the collision and/or a physical parameter of an occupant seated in the front seat, which will be described in detail later.
In one embodiment, the first predetermined condition includes the front seat being in a position that allows the space to be enlarged relative to the rear seat. The bit states include, for example: the front seat is in a non-occupant occupying state, the seat back 301 of the front seat 300 can rotate forward at least at an angle (as indicated by arrow A1 in fig. 3), or to a maximum angle, and the front seat 300 can move forward as a whole (as indicated by arrow A2 in fig. 3), preferably to a forwardmost allowable position; the front seat 300 is in the occupant occupying state, but it is determined that the front seat 300 is still in the adjustable state based on the front seat state detected in step S2, and for example, the seatback 301 may be rotated forward by a limited angle and/or the seat as a whole may be moved forward by a limited distance, or the like.
In one embodiment, the second predetermined condition includes the rear seat being in an occupant occupancy state. That is, when the rear seat is in the non-occupant occupying state, the rear seat state does not satisfy the second predetermined condition, and the front seat corresponding to the non-occupant rear seat does not need to be controlled to expand the rear evacuation space.
In an alternative embodiment, the second predetermined condition may also include that the body parameter of the rear occupant is above a certain reference value, for example the weight of the rear occupant is above a predetermined value, such as above 50kg, etc. That is, when the rear passenger is light in weight or small in size, it is possible to consider a control that does not enlarge the rear space of the front seat corresponding to the rear seat to protect the rear passenger, which is advantageous for protecting the front passenger when the front seat is in the passenger occupying state, particularly in the case where the front passenger is excessively heavy, for example.
In one embodiment, when the obtained detection result indicates that the front seat is in the non-occupant occupying state and the rear seat is in the occupant occupying state, it is determined that the front seat state satisfies the above-described first predetermined condition and the rear seat state satisfies the second predetermined condition, and then the rear evacuation room is allowed to increase by allowing at least the front seat as a whole to move forward by a first predetermined distance and/or the seat back of the front seat to rotate forward by a first predetermined angle, which may be specifically set according to crash test data or according to actual circumstances, without limitation, as long as sufficient movement and rotation can be achieved to effectively enlarge the rear evacuation room.
In a preferred embodiment, the rear space is increased by moving the front seat as a whole to the forwardmost allowable position and/or rotating the seat back of the front seat forward to the maximum allowable angle when the front seat is in the non-occupant occupying state and the rear seat is in the occupant occupying state. The forwardmost allowable position is an extreme position at which the seat can be moved forwards in the occupant-free state, and the maximum allowable angle is, for example, an angle at which the seat is fully folded to contact the seat back. In this way, the largest possible rear space is given to the rear passenger, so that the possibility of the rear passenger colliding with, for example, a seat back portion of the front seat during collision is largely avoided, and the effect of protecting the rear passenger during collision is largely improved.
In one embodiment, when the obtained detection result indicates that the front seat is in the occupant occupying state and the rear seat is also in the occupant occupying state, an allowable adjustment parameter of the front seat is calculated from the front seat state obtained in step S2, and it is determined whether the front seat state satisfies a first predetermined condition based on the calculated allowable adjustment parameter, and when it is determined that the front seat state satisfies the first predetermined condition, the front seat is adjusted based on the allowable adjustment parameter so that the space is increased.
In one embodiment, when the front seat state is judged to satisfy the first predetermined condition, the space is allowed to increase by allowing at least the front seat as a whole to move forward by a second predetermined distance and/or the seatback of the front seat to rotate forward to a second predetermined angle. The second predetermined distance and the second predetermined angle are smaller than the first predetermined distance and the first predetermined angle, respectively, optionally may be a fixed distance and a fixed angle that are much smaller than the first predetermined distance and the first predetermined angle, respectively, and preferably may also be calculated based on the allowable adjustment parameters.
In a preferred embodiment, the adjustment allowing parameter is determined based on the current position of the front seat and/or the physical parameters of the occupant, wherein the current position includes the current position and the chair back posture of the seat, and the physical parameters of the occupant include height, weight and the like. Preferably, the allowable adjustment parameter and the judgment as to whether or not the front seat state satisfies the first predetermined condition may be determined as follows: when the weight of the passenger is larger than a preset weight limit value (such as 80kg, 90kg and the like) and/or the front seat reaches the foremost allowable position, the allowable adjustment parameter is determined to be a first threshold value, such as 0, and then the state of the front seat is determined not to meet the first preset condition; when the weight of the passenger is lower than the preset weight limit value, the allowable adjustment parameter is calculated to be in direct proportion to the remaining forwards movable distance of the seat and in inverse proportion to the weight of the passenger, namely the smaller the remaining forwards movable distance of the seat and/or the heavier the weight of the passenger, the smaller the allowable adjustment parameter is, when the calculated allowable adjustment parameter is larger than a second threshold value, the state of the front-row seat is judged to meet the first preset condition, and when the calculated allowable adjustment parameter is smaller than the second threshold value, the state of the front-row seat is judged to not meet the first preset condition. The second threshold value is set to avoid injury to the front passenger due to adjustment and control of the seat caused by an error caused by measurement or calculation, and may be any appropriate value determined by a large number of experiments and calculations as long as no additional injury to the front passenger can be caused. Of course, the allowable adjustment parameters may alternatively or additionally be calculated as a function of the occupant height and the seat back posture; various parameters of the seat and the height can be properly selected according to the actual condition or the preset condition to calculate the allowable adjustment parameters; the forward moving distance of the seat and/or the adjustable angle of the seat back can be further calculated according to the calculated allowable adjustment parameter after the condition of the front row seat is judged to meet the first preset condition based on the allowable adjustment parameter; the allowable adjustment parameters may also be calculated with reference to parameters based on the body posture of the occupant as appropriate. In summary, it is sufficient if it is possible to determine the adjustment permission parameter based on the current posture of the front seat and/or the physical parameter of the occupant and determine whether the front seat state satisfies the first predetermined condition based on the determined adjustment permission parameter.
