In addition, in some embodiments, the at least one side wing support includes a first side wing support disposed on a left side of the seat and a second side wing support disposed on a right side of the seat, wherein the driving state information further includes steering information, and controlling the working state of the side wing support according to the driving state information further includes:
And if the steering information of the vehicle is that the vehicle turns right, controlling the working state of the first side wing support to be a supporting state, and if the steering information of the vehicle is that the vehicle turns left, controlling the working state of the second side wing support to be a supporting state. The support force opposite to the steering can be provided for the passengers, so that the centripetal force effect is provided for the passengers, and the comfort is improved.
In some examples, controlling the working state of the side wing support according to the driving state information further includes controlling the working state of the first side wing support and/or the second side wing support to be a support state if the steering angle of the vehicle is greater than the second angle threshold value and the vehicle is in a steering state (the vehicle speed may be in an increased, decreased or maintained state). The second side wing support may be set to a support state (the first side wing support may be set to a support state, or a release state) when the vehicle is turning to the left, and the first side wing support may be set to a support state (the second side wing support may be set to a support state, or a release state) when the vehicle is turning to the right.
For example, the side wing support can comprise a first air bag arranged on the left side of the seat and a second air bag arranged on the right side of the seat, wherein the first air bag and the second air bag are in a support state after the inflation amount reaches a preset value, and the first air bag and the second air bag are in a release state after the deflation. The first air bag and the second air bag are connected through the air pump and the control valve, so that the adjustment of the air storage capacity in the air bags is realized. According to the above example of the present application, when the occupant gets on the vehicle and buckles the seat belt, and the vehicle speed reaches the vehicle speed threshold (for example, 40KM/h, which may be a calibrated fixed value or an adjustable value), it is detected that the left angle signal value is greater than or equal to the second angle threshold B2 (for example, 10 ° or a calibrated fixed value or an adjustable value), the triggering module sends an inflation signal Qn, triggers the control valve to connect the second air bag and the air pump channel, and drives the air pump to operate so as to inflate the connected second air bag, the occupant leans rightwards due to inertia, the inflatable air bag plays a role in supporting the right side of the occupant, the preset time period (for example, 3s or a calibrated fixed value or an adjustable value) is maintained after the inflation is finished, if the steering angle is back-regulated, the control valve sends a deflation signal, and the control valve performs a deflation action, and deflates, otherwise, the original inflated state is maintained. And when the vehicle speed reaches a vehicle speed threshold (for example, 40KM/h, which can be a calibrated fixed value or an adjustable value), detecting that the right angle signal value is greater than or equal to a second angle threshold B2 (for example, 10 degrees, which can be a calibrated fixed value or an adjustable value), sending an inflation signal Qn by a trigger module, triggering a control valve to connect the first air bag and an air pump passage, driving the air pump to work so as to inflate the connected first air bag, enabling the occupant to tilt left due to inertia, enabling the air bag to support the left side of the occupant, keeping a preset time period (for example, 3s, which can be a calibrated fixed value or an adjustable value) after the inflation is finished, and if the steering angle is back-regulated, sending an deflation signal, controlling the valve to execute deflation action and deflating the air bag.
In some embodiments, the working state further includes a pre-supporting state, and the controlling the working state of the side wing support according to the driving state information further includes controlling the working state of at least one side wing support to be the pre-supporting state if the steering angle is smaller than the second angle threshold and larger than the first angle threshold, and the vehicle is in a steering state at this time, but the steering angle is smaller, and the side wing support may not need to be in the supporting state, wherein the first angle threshold is smaller than the second angle threshold. By setting the pre-supporting state, the flank support is in a supporting state and a releasing state, and when the flank support needs to be adjusted to the supporting state, the time required by the flank support from the pre-supporting state to the supporting state is smaller than the time required by the flank support from the releasing state to the supporting state, so that the time from the releasing state to the supporting state of the flank support can be shortened, and the rapid response of the flank support can be realized.
Wherein the pre-support state of the side wing support is a state between the release state and the support state. For example, the side wing support comprises an air bag, and the first inflation amount of the air bag when the working state of the side wing support is the pre-support state is smaller than the second inflation amount of the air bag when the working state is the support state. Thus, before the flank support is about to enter the support state, part of gas is introduced into the air bag in advance, and when the air bag needs to be continuously inflated, the time for inflating the air bag to the support state is shortened.
For example, according to the above example of the present application, when the passenger gets on the vehicle and buckles the seat belt, the vehicle speed reaches the vehicle speed threshold (for example, 40KM/h, which may be a calibrated fixed value or an adjustable value), the left angle signal value is detected to be greater than the first angle threshold and smaller than the second angle threshold (for example, between 5 ° and 10 °, which may be a calibrated fixed value or an adjustable value), the trigger module sends a pre-inflation signal, triggers the control valve to switch on the second air bag and the air pump passageway, and drives the air pump to operate so as to inflate the second air bag, at this time, the inflation amount of the second air bag is smaller than the inflation amount in the supporting state, and continues to inflate the second air bag when the steering angle continues to be greater than or equal to the second angle threshold (for example, greater than 10 °), and when the right angle signal value is detected to be greater than the first angle threshold and smaller than the second angle threshold (for example, between 5 ° and 10 °, which may be a calibrated fixed value or an adjustable value), the trigger module is triggered to send a pre-inflation signal, and the trigger control valve is switched on the second air bag and the air pump is driven to operate so as to inflate the second air bag, at this time, the inflation amount of the second air bag is continuously equal to the first air bag and the first air bag is inflated to the first air bag is continuously in the supporting state when the steering angle is greater than or equal to the second angle.
In embodiment 3, the driving state information further includes a vehicle speed, and the controlling the working state of the side wing support according to the driving state information further includes controlling the working state of the side wing support according to the driving state information if the vehicle speed of the vehicle is greater than or equal to a vehicle speed threshold value, and/or controlling the working state of the side wing support to be the release state if the vehicle speed of the vehicle is less than the vehicle speed threshold value. The passenger support device can judge whether the flank support needs to be adjusted to be in a supporting state according to the vehicle speed, can provide support for passengers without the flank support when the vehicle speed is low, and can rapidly utilize the flank support to provide support for the passengers when the vehicle speed is high.
The embodiment 4 further includes a seat occupation signal, and the controlling the working state of the side wing support according to the driving state information further includes controlling the working state of the side wing support according to the driving state information if the seat occupation signal of the vehicle is that an occupant is seated, and/or controlling the working state of the side wing support to be the release state if the seat occupation signal of the vehicle is that no occupant is seated.
For example, FIG. 3 is a flank support follow-up adjustment workflow.
