Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a flow chart of a method for controlling adjustment of a power seat of a vehicle according to an embodiment of the present invention is shown, where the method includes:

s10, responding to an adjusting instruction for adjusting the position of an electric seat corresponding to a vehicle, acquiring a target position parameter of the electric seat in a preset vehicle seat position coordinate system, and acquiring a current position parameter of an adjacent seat in the position adjusting direction of the electric seat in the coordinate system; the target position parameter corresponds to the adjustment instruction;

s11, checking whether the position adjusting space in the current position adjusting direction of the electric seat is sufficient according to the target adjusting position parameter and the current position parameter;

s12, if sufficient, adjusting the electric seat to a target position corresponding to the target position parameter;

and S13, if the position is insufficient, carrying out avoidance processing on the seat positions of the electric seat and the adjacent seat according to the target position parameter and the current position parameter.

In this embodiment, the method may be performed by a vehicle control device (e.g., a body area controller) on a vehicle.

In this embodiment, for example, when the vehicle control device receives the adjustment instruction, the vehicle control device may obtain the target position parameter of the power seat in the coordinate system and obtain the current position parameter of the adjacent seat in the coordinate system in response to the adjustment instruction. The adjustment instruction may be issued by an occupant through an operation of an instruction generation system for adjusting the power seat of the vehicle, for example, the occupant may issue the adjustment instruction to the vehicle control device through a touch operation or a key operation of a center screen device mounted on the vehicle, or may issue the adjustment instruction to the vehicle control device through a voice instruction input to a voice input device mounted on the vehicle. Of course, the adjustment instruction may also be automatically generated by the vehicle control device according to a related processing result in the process of adjustment control, for example, when analyzing whether the calculated avoidance position of a certain electric seat of the vehicle interferes with an adjacent seat in the avoidance direction, an adjustment instruction may be generated, and then a target position (i.e., the avoidance position) to which the electric seat needs to be subjected to avoidance adjustment and a current position of the adjacent seat in the avoidance direction may be obtained.

Alternatively, the adjustment instruction may be for adjusting one power seat, or may be for adjusting two or more power seats simultaneously. The relationship between the adjustment command and the power seat to be adjusted in position may be established in advance, or may be analyzed based on the adjustment command.

In this embodiment, the target position parameter may be calculated according to the adjustment instruction (for example, if the adjustment instruction is that the seat moves backward by 5cm, the target position parameter is that the current position parameter of the seat moves backward by 5cm), or may be obtained correspondingly according to the adjustment instruction (for example, if the adjustment instruction is that one key of the left electric seat is comfortable, the target position parameter is that a preset target position parameter is obtained according to the instruction, where the corresponding relationship between the instruction and the target position parameter is preset).

In the present embodiment, the criterion for checking whether the position adjustment space in the current position adjustment direction of the power seat is sufficient may be: after the electric seat is adjusted to the target position, normal sitting of the adjacent seat is not influenced; or, it may be: the electric seat does not interfere with the adjacent seat after being adjusted to the target position. And is not particularly limited herein.

In the present embodiment, it can be understood that the avoidance position can provide sufficient space for adjusting the position of the power seat.

In this embodiment, the adjacent seat is located adjacent to the power seat, for example, in front and rear of the power seat, or in left and right of the power seat.

In summary, in the embodiments of the present invention, whether the position adjustment space in the current position adjustment direction of the electric seat is sufficient is checked by comparing the target position parameter of the electric seat that needs to be subjected to position adjustment and the current position parameter of the adjacent seat in the position adjustment direction, and when it is determined that the position adjustment space is insufficient and the adjacent seat is of the electric type, the seat positions of the electric seat and the adjacent seat are avoided according to the target position parameter and the current position parameter, so as to ensure the position adjustment of the electric seat, and the problem of insufficient adjustment space does not occur. Therefore, the embodiment of the invention can check the position adjusting space of the electric seat before the electric seat is adjusted to the target position, so as to avoid the problem that the position adjusting space is insufficient when the electric seat is adjusted to the target position. In addition, different from the prior art that only one adjustment command can adjust the position of one power seat, the embodiment of the invention can control the position adjustment of one or more power seats (i.e. the adjustment is performed in a centralized control manner) by one adjustment command, so that the adjustment of the power seats of the vehicle can be realized more quickly and conveniently.

It is further noted that, in the conventional adjustment method of the power seat, only a single adjustment of a certain power seat can be realized, and linkage adjustment of two seats or more than two seats cannot be realized, so that when a passenger adjusts a certain power seat, if the power seat is found to be adjusted to a target position, a space between the seat and an adjacent seat in the current position adjustment direction is insufficient (for example, the two seats interfere with each other in position, or the space between the two seats makes the passenger sitting on the adjacent seat uncomfortable), the passenger needs to manually adjust the position of the adjacent seat. Therefore, the existing adjusting method for the electric seat of the vehicle is tedious and time-consuming.

In order to solve the technical problem in the prior art, a further improvement of the present embodiment is proposed herein: specifically, the step S13 includes:

s130, if the number of the adjacent seats is insufficient and the adjacent seats are judged to be of the electric type, calculating avoidance positions of the adjacent seats according to the target position parameters and the current position parameters;

specifically, the calculated avoidance position should be such that a position space between the electric seat adjusted to the target position and the adjacent seat adjusted to the avoidance position satisfies a sufficient condition. For example, if the power seat and the adjacent seat are both in the lateral direction of the coordinate system (i.e., the X direction of the coordinate system), the target position parameter has a coordinate of +50cm on the X axis of the coordinate system, and the current position parameter has a coordinate of +70cm on the X axis of the coordinate system. If the position space between the two is sufficient, the following conditions are satisfied: the distance between the two seats is at least 30cm, then the avoidance positions of the adjacent seats are as follows: the coordinate on the X axis of the coordinate system is +80cm or more.

S131, adjusting the adjacent seats to avoidance positions, and adjusting the electric seats to target positions corresponding to the target position parameters.

In the embodiment of the invention, whether the position adjusting space in the current position adjusting direction of the electric seat is sufficient is checked by the target position parameter of the electric seat needing position adjustment and the current position parameter of the adjacent seat in the position adjusting direction, and when the judgment is insufficient and the adjacent seat is of an electric type, the avoiding position of the adjacent seat is calculated according to the two parameters, and finally, the electric seat can be automatically adjusted to the target position and the adjacent seat to the avoiding position, and the space between the electric seat and the avoiding position can be ensured to meet the sufficient requirement. Therefore, in the embodiment of the invention, the electric seat of the vehicle can be automatically adjusted in a linkage manner by adopting a centralized adjustment manner for the adjustment manner of the electric seat, so that the adjustment process of the electric seat of the vehicle can be more efficient and faster.

The mode of performing the avoidance process on the seat positions of the electric seat and the adjacent seat may be: if the adjacent seat is of a non-electric type, the position of the adjacent seat is not adjusted, and the target position of the electric seat is only readjusted to calculate a new target position, and the new target position can enable the position adjusting space of the electric seat to meet sufficient requirements, so that the position of the adjacent seat is avoided. Or can also be: if the adjacent seats are of the electric type, the avoidance positions of the adjacent seats can be calculated at the same time, and the target positions of the electric seats can be recalculated, so that the new target positions and the avoidance positions can meet the requirement of the position adjusting space of the electric seats.

As a modification of the above scheme, the step S130 includes:

if the adjustment is insufficient and the adjacent seat is judged to be of the electric type, judging whether the adjustment of the electric seat is of the strong demand type;

if so, calculating an avoidance position of the adjacent seat according to the target position parameter and the current position parameter;

and if not, stopping executing the position adjustment work of the electric seat.

In this embodiment, the adjustment of the high demand type, which is defined as the calling out of the target position of the seat with high demand requires the adjustment of the avoidance of the adjacent seat, may be: easy entry (i.e., to facilitate the entry and exit of the occupant, such as for the third row of passengers, the second row of seats move forward, and the backrest is stowed), or, to actively adjust the first row of seats to meet the requirements of the second row of cabins, etc. The adjustment of the weak demand type may be: if the two rows of seats are comfortable by one key (if the two rows of seats are set to be comfortable lying postures by the switch key, the seat is controlled to avoid when no passenger is in the same row of seats, and meanwhile, a safety space is reserved for the passengers in the three rows of seats.

s1310, substituting the target position parameter and the current position parameter into a preset avoidance position calculation formula, and calculating a solution of the avoidance position of the adjacent seat; at least one solution to the avoidance position;

s1311, selecting a solution with the minimum total adjusting time of each adjusting motor of the adjacent seat as an avoidance position of the adjacent seat.

In this embodiment, a solution with the minimum total adjustment time of each adjustment motor of the adjacent seat is selected as an avoidance position, so that the adjustment of the adjacent seat is faster and more efficient.
