Description

Technical Field

[0001] The present application relates to the field of vehicle control technology, and in particular to a scenario-based seat adjustment method, system, vehicle and equipment. Background Art

[0002] With the development of vehicles, in addition to the increasingly dazzling cockpit, the comfort of the cockpit is also gradually valued by drivers and passengers. For example, many electric passenger cars are promoting the acceleration of 100 kilometers as a measure of vehicle power performance, but during the acceleration process, the driving experience of the passengers is ignored, especially the rear passengers will feel very obvious push back and discomfort.

[0003] In the related technology, the first solution is to make the seat rail into a sliding rail type, and slide the sliding rail wheel according to the state of vehicle acceleration to reduce the push-back feeling; the second solution is to adjust the two side wings of the seat according to the lateral acceleration to protect the occupants; the third solution is to reduce the bumpy feeling caused by uneven road surface by collecting the weight of the occupants and related vehicle information. However, the state of the sliding rail in the first solution is not easy to control, and it is easy to wear out after sliding for a long time, and regular replacement increases the cost; the second solution is a pre-processing of the lateral acceleration, and does not consider whether the occupants have a tightening feeling when tightening; the third solution considers the up and down bumps caused by the uneven road surface, and does not consider the lateral impact force during driving. Summary of the invention

[0004] Based on this, it is necessary to provide a scenario-based seat adjustment method, system, vehicle and equipment to address the above technical problems. This can reduce the impact on passengers when the vehicle accelerates or decelerates suddenly or even collides, resulting in large acceleration changes in the front and rear of the vehicle, thereby making driving more comfortable, and effectively improving the stickiness between users and vehicles and enhancing the vehicle's riding experience.

[0009] Therefore, during driving, the vehicle's state can be judged according to the vehicle's acceleration, such as when it is in a state of rapid acceleration / sudden deceleration, and the overall tilt angle of the seat can be quickly adjusted. Therefore, when the vehicle is rapidly accelerated or decelerated or even collides, resulting in large acceleration changes in the front and rear of the vehicle, the impact on the occupants can be reduced, making the ride more comfortable, and thus effectively improving the stickiness between the user and the vehicle and the riding experience of the vehicle.

[0014] determining whether the vehicle is in a collision state according to the acceleration;

[0015] If yes, the tightening force of the seat belt is increased and the seat state is adjusted according to the vehicle speed.

[0016] In some examples, adjusting the seat state according to the vehicle speed includes:

[0025] In some examples, the control module is further configured to increase the tightening force of the seat belt when the vehicle is in a collision state and to adjust the seat state according to the vehicle speed.

[0026] In a third aspect, a vehicle is provided, comprising: a scenario-based seat adjustment system according to the second aspect.

[0037] The present application is further described in detail below in conjunction with the embodiments and drawings. It is to be understood that the specific embodiments described herein are only used to explain the relevant application, rather than to limit the application. It is also necessary to explain that, for ease of description, only the parts related to the application are shown in the drawings.

[0038] It should be noted that, in the absence of conflict, the embodiments of the present application, that is, the features of the embodiments, can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] The following describes in detail the scenario-based seat adjustment method, system, vehicle and device according to the embodiments of the present application in conjunction with the accompanying drawings.

[0040] Figure 1 FIG. 1 is a flow chart of a scenario-based seat adjustment method according to an embodiment of the present application. Figure 1 As shown, the scenario-based seat adjustment method according to an embodiment of the present application includes the following steps:

[0041] S101: During driving, the acceleration of the vehicle is obtained.

[0042] S102: Determine whether the vehicle is in a rapid acceleration / deceleration state according to the acceleration.

[0043] S103: If yes, then when there is a person on the seat, adjust the overall inclination angle of the seat, wherein when adjusting the overall inclination angle of the seat, keep the angle between the seat back and the seat cushion and the tightening force of the seat belt consistent with the initial angle and initial tightening force of the seat pre-adjusted.

[0044] In one embodiment of the present application, adjusting the tilt angle of the entire seat includes: determining the tilt angle according to the magnitude and direction of the acceleration; and controlling the entire seat to rotate around the seat rotation axis according to the determined tilt angle.

[0045] It should be noted that the pre-adjusted initial angle and initial tightening force of the seat refer to the angle and tightening force adjusted after the person gets on the vehicle.

[0046] In addition, the scenario-based seat adjustment method also includes: determining whether the vehicle is in a collision state based on the acceleration; if so, increasing the tightening force of the seat belt and adjusting the seat state according to the vehicle speed.

[0047] Specifically, when the vehicle is in a collision state, adjusting the seat state according to the vehicle speed includes: if the vehicle speed is lower than a low speed threshold, adjusting the overall tilt angle of the seat.

[0048] When in a collision state, adjusting the seat state according to the vehicle speed also includes: if the vehicle speed is higher than a high speed threshold, adjusting the seat to a limit state according to the collision direction of the vehicle.

[0049] In the above description, the seats are usually rear seats.

[0050] In specific applications, combined Figure 2 As shown, when a person (ie, an occupant) gets on the bus, the occupant adjusts the seat comfort angle, including the backrest, the cushion state, and the seat belt tightening state. After the adjustment is completed, the seat controller records the angle and the tightening force.

[0051] When driving, take the rapid acceleration / deceleration state as an example:

[0052] First, the acceleration sensor evaluates the acceleration state in the horizontal direction and determines whether the current acceleration or deceleration is normal rather than a collision.

[0053] Then, according to the direction and magnitude of the acceleration, the overall state of the seat is adjusted, for example: the comfortable angle of the seat is kept unchanged, and the inclination of the entire seat is adjusted by rotating the backrest and seat cushion around the seat axis. Figure 3 As shown, the seat rotates backwards as a whole around the seat axis.

[0054] In addition, the seat belt tensioning force remains unchanged in rapid acceleration / deceleration conditions rather than in collision conditions.

[0055] When driving, take the collision state as an example:

[0056] First, when the vehicle acceleration reaches the limit, it is determined that the vehicle is in a collision state;

[0057] Then, combined with the current vehicle speed, if the current vehicle speed is very low, the seat belt will be tightened immediately to serve as a first-level warning. At the same time, the seat will rotate as a whole according to the rapid acceleration / deceleration state;

[0058] If the current vehicle speed is very high, while tightening the seat belt, immediately adjust the seat to the most extreme state according to the direction of the vehicle collision. It should be noted that after the instantaneous state ends, the seat slowly returns to the comfortable state when getting on the vehicle.

[0059] According to the scenario-based seat adjustment method of the embodiment of the present application, during driving, the vehicle state is judged according to the vehicle acceleration, such as when in a state of rapid acceleration / rapid deceleration, the overall tilt angle of the seat is quickly adjusted. Therefore, when the vehicle is rapidly accelerated or decelerated or even collides, resulting in a large acceleration change in the front and rear of the vehicle, the impact on the occupants can be reduced, making the ride more comfortable, thereby effectively improving the stickiness between the user and the vehicle and improving the vehicle's riding experience.

[0060] Figure 4 is a structural block diagram of a scene-based seat adjustment system according to an embodiment of the present application. Figure 4 As shown, according to an embodiment of the present application, the scenario-based seat adjustment system includes: an acquisition module 410, a judgment module 420 and a control module 430, wherein:

[0061] The acquisition module 410 is used to obtain the acceleration of the vehicle during driving;

[0062] A determination module 420, configured to determine whether the vehicle is in a rapid acceleration / deceleration state according to the acceleration;

[0063] The control module 430 is used for adjusting the overall inclination angle of the seat when there is a person on the seat when the vehicle is in a state of rapid acceleration / deceleration, wherein when adjusting the overall inclination angle of the seat, the angle between the seat back and the seat cushion and the tightening force of the seat belt are kept consistent with the initial angle and initial tightening force of the seat pre-adjusted.

[0064] In one embodiment of the present application, the control module 430 is further configured to increase the tightening force of the seat belt when the vehicle is in a collision state, and adjust the seat state according to the vehicle speed.

[0065] Specifically, combined Figure 2 As shown, when a person (ie, an occupant) gets on the bus, the occupant adjusts the seat comfort angle, including the backrest, the cushion state, and the seat belt tightening state. After the adjustment is completed, the seat controller records the angle and the tightening force.

[0066] When driving, take the rapid acceleration / deceleration state as an example:

[0067] First, the acceleration sensor evaluates the acceleration state in the horizontal direction and determines whether the current acceleration or deceleration is normal rather than a collision.

[0068] Then, according to the direction and magnitude of the acceleration, the overall state of the seat is adjusted, for example: the comfortable angle of the seat is kept unchanged, and the inclination of the entire seat is adjusted by rotating the backrest and seat cushion around the seat axis. Figure 3 As shown, the seat rotates backwards as a whole around the seat axis.

[0069] In addition, the seat belt tensioning force remains unchanged in rapid acceleration / deceleration conditions rather than in collision conditions.

[0070] When driving, take the collision state as an example:

[0071] First, when the vehicle acceleration reaches the limit, it is determined that the vehicle is in a collision state;

[0072] Then, combined with the current vehicle speed, if the current vehicle speed is very low, the seat belt will be tightened immediately to serve as a first-level warning. At the same time, the seat will rotate as a whole according to the rapid acceleration / deceleration state;

[0073] If the current vehicle speed is very high, while tightening the seat belt, immediately adjust the seat to the limit state according to the direction of the vehicle collision. It should be noted that after the instantaneous state ends, the seat slowly returns to the comfortable state when getting on the vehicle.

[0074] According to the scenario-based seat adjustment system of the embodiment of the present application, during driving, the vehicle state is judged according to the vehicle acceleration, such as when in a state of rapid acceleration / sudden deceleration, the overall tilt angle of the seat is quickly adjusted. Therefore, when the vehicle is rapidly accelerated or decelerated or even collides, resulting in a large acceleration change in the front and rear of the vehicle, the impact on the occupants can be reduced, making the ride more comfortable, thereby effectively improving the stickiness between the user and the vehicle and improving the vehicle's riding experience.
