[0022] Figure 4 This is a flowchart of a vehicle suspension adjustment method according to an embodiment of this application. Detailed Implementation

[0023] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0024] The following description, with reference to the accompanying drawings, describes an embodiment of the suspension, a vehicle suspension adjustment method, a vehicle, and a storage medium. Addressing the problems mentioned in the background art, this application provides a suspension system. In this method, a first detection component detects the compression distance of an elastic element, and the increased weight of the corresponding detection area of ​​the suspension is calculated based on the compression distance to determine the damping adjustment value of the elastic element. The actual damping of the elastic element is adjusted using the damping adjustment value, thereby achieving adaptive adjustment of the vehicle suspension. This solves the problems in related technologies where suspension systems cannot adaptively adjust, resulting in poor vehicle ride comfort and handling stability, thus reducing the user's driving experience.

[0025] Specifically, Figure 1 This is a block diagram of a suspension system provided in an embodiment of this application.

[0026] like Figure 1 As shown, the suspension 101 includes: a suspension body, an elastic element 100 disposed on the suspension body, a first detection component 200, and an adjustment unit 300.

[0027] The elastic element 100 is disposed on the suspension body; the first detection component 200 is used to detect the compression distance of the elastic element, wherein the increased weight of the corresponding detection area of ​​the suspension is calculated based on the compression distance, and the damping adjustment value of the elastic element is determined based on the increased weight; the adjustment unit 300 is used to adjust the actual damping of the elastic element according to the damping adjustment value.

[0028] Specifically, such as Figure 2 The diagram shows a vehicle suspension, where 01 represents the vehicle body, 02 represents the vehicle floor, 03 represents the suspension position, and 04 represents the area that the suspension can sense. This embodiment detects the compression distance of the elastic element using a first detection component, and calculates and accurately obtains the change in weight inside the vehicle. This allows for the location of changes in vehicle energy and weight quantity / position within the vehicle, and the damping adjustment value of the elastic element is determined based on the increased weight, thus enabling suspension adjustment in response to dynamic weight movement within the vehicle.

[0029] In one embodiment of this application, the first detection component 200 includes a first detection unit and a second detection unit. The first detection unit and the second detection unit are disposed at different positions on the suspension body, and the first detection unit and the second detection unit sense each other, determining the compression distance of the elastic element based on the mutual sensing signals.

[0030] like Figure 2 As shown, the first detection unit 05 represents the lidar on the suspension, and the second detection unit 06 represents the lidar under the suspension. In this embodiment, the suspension elastic components are calibrated before installation to calculate the weight required for 0.1 cm, resulting in data A. The first detection unit 05 and the second detection unit 06 sense each other during vehicle use. The first detection unit 05 sends a signal to the second detection unit 06, and the second detection unit 06 sends a signal to the first detection unit 05. If signals are sent simultaneously, bidirectional double verification can be performed. By determining the number of centimeters B, the actual increase in weight can be calculated using the formula B / 0.1cm*A.

[0031] The suspension proposed in this application detects the compression distance of the elastic element and calculates the increased weight of the corresponding detection area of ​​the suspension based on the compression distance to determine the damping adjustment value of the elastic element. This method is highly accurate, and the actual damping of the elastic element is adjusted using the damping adjustment value to achieve adaptive adjustment of the vehicle suspension. This solves the problems in related technologies where the suspension system cannot adaptively adjust, resulting in poor ride smoothness and handling stability, thus reducing the user's driving experience.

[0032] Next, a vehicle according to an embodiment of this application is described with reference to the accompanying drawings.

[0033] Figure 3 This is a block diagram of a vehicle according to an embodiment of this application.

[0034] like Figure 3 As shown, the vehicle 20 includes: a suspension 101, a computing unit 07, and a processor 09 as described in the above embodiment.

[0035] The calculation unit 07 calculates the increased weight of the corresponding detection area of ​​the suspension based on the compression distance of the suspension; the processor 09 determines the damping adjustment value of the elastic element based on the actual increased weight, and adjusts the actual damping of the elastic element based on the damping adjustment value.

[0036] It is understandable that, such as Figure 2 As shown, in this embodiment of the application, the calculation unit 07 can calculate the increased weight of the corresponding detection area 04 of the suspension based on the compression distance of the suspension. The processor 09 determines the damping adjustment value of the elastic element by processing the data calculated by the calculation unit 07 and sends it to the suspension information command sending unit 10. The suspension information command sending unit 10 receives the signal sent by the processor 09 and sends it to the suspension damping control unit 11. The suspension damping control unit 11 adjusts the damping according to the transmitted signal and the increase in weight to achieve a faster response.

[0037] In actual implementation, the embodiments of this application can reflect the vehicle weight and adjustments caused by real-time weight changes inside the vehicle, as well as energy consumption, in a more intuitive and realistic way on the remaining battery power, making it convenient for users to view and control.

[0038] It should be noted that the calculation process of the first detection unit 05 and the second detection unit 06 in the embodiments of this application is completed in the calculation unit 07; under the same weight and working conditions, different vehicles have different designs and structures, and the corresponding damping adjustment values ​​of the elastic elements are also different.

[0039] The vehicle proposed in this application determines the damping adjustment value of the elastic element by increasing the weight in any detection area of ​​the vehicle, achieving high accuracy. The actual damping of the elastic element is then adjusted using this damping adjustment value, enabling adaptive adjustment of the vehicle suspension. This solves the problems in related technologies where the suspension system cannot adaptively adjust, resulting in poor ride smoothness and handling stability, thus reducing the user's driving experience.

[0040] In addition, such as Figure 4 As shown in the embodiments of this application, a vehicle suspension adjustment method is also proposed, applied to the suspension as described in the above embodiments, or, for the vehicle as described in the above embodiments, including the following steps:

[0041] In step S101, the increased weight of any detection area in the vehicle is obtained, wherein the increased weight is calculated based on the compression distance of the suspension corresponding to the detection area.

[0042] In step S102, the damping adjustment value of the elastic element is determined based on the increased weight, and the actual damping of the elastic element is adjusted using the damping adjustment value.

[0043] It is understandable that getting in and out of the vehicle, as well as the movement of passengers and their belongings inside the vehicle, have a significant impact on the vehicle's center of gravity. However, the suspension is more sensitive and covers a larger area than the weight sensors inside the vehicle. Therefore, the embodiments of this application can use the suspension applied to the vehicle to accurately obtain the damping adjustment value of the elastic element that determines the increase in weight in the vehicle's detection area. This allows the weight change to be transmitted to the vehicle's processor in real time, enabling suspension adjustment under dynamic weight movement inside the vehicle to ensure smooth driving and handling stability.

[0044] In one embodiment of this application, after adjusting the actual damping of the elastic element using the damping adjustment value, the method further includes: acquiring road condition information around the vehicle; identifying the road condition information, determining the road condition type of the road where the vehicle is currently located, determining the damping correction value of the elastic element based on the road condition type, and correcting the actual damping using the damping correction value.

[0045] To further improve the user's driving experience, this application embodiment can acquire and monitor the road conditions around the vehicle in real time, and adjust the damping of the elastic element according to the working conditions inside and outside the vehicle. When the vehicle passes through a bumpy road, the vehicle suspension stiffness and frequency will adaptively change according to the road conditions, thereby providing sufficient support for the vehicle suspension and avoiding interference from various factors under dynamic conditions, so as to ensure that the vehicle can drive smoothly.

[0046] In one embodiment of this application, after adjusting the actual damping of the elastic element using the damping adjustment value, the method further includes: identifying the driver's adjustment intention for any suspension; and adjusting the actual damping of any suspension according to the adjustment intention.

[0047] It is understood that after adjusting the actual damping of the spring component in this embodiment, the driver can also make adjustments according to the actual situation of the vehicle. For example, if there is a heart patient in the vehicle who cannot tolerate bumps, this embodiment can monitor the working conditions inside and outside the vehicle, and according to the driver's adjustment intention, coordinate with the vehicle body processor to prioritize the allocation of balance and comfort inside the vehicle to ensure that the vehicle can drive smoothly and avoid causing secondary harm to the patient.

[0048] The vehicle suspension adjustment method also proposed in this application determines the damping adjustment value of the elastic element by increasing the weight in any detection area of ​​the vehicle, which is highly accurate. The actual damping of the elastic element is then adjusted using the damping adjustment value, achieving adaptive adjustment of the vehicle suspension. This solves the problems in related technologies where the suspension system cannot adaptively adjust, resulting in poor ride comfort and handling stability, thus reducing the user's driving experience.

[0049] This application also provides a computer-readable storage medium storing a computer program thereon, which, when executed by a processor, implements the above-described vehicle suspension adjustment method.
