[0032] The embodiments of the present disclosure will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where 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 are intended to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0033] In the technical solution of the present disclosure, the acquisition, storage, use, processing, etc. of data all comply with the relevant regulations of national laws and regulations.

[0034] Figure 1 It is a schematic structural diagram of an air suspension system of a vehicle according to an embodiment of the present disclosure. As Figure 1 shown, the air suspension system of the vehicle includes: a controller 110 and a first air suspension 120.

[0035] In the embodiment of the present disclosure, the structure of the first air suspension can be referred to Figure 2 as shown, Figure 2 This is a schematic structural diagram of a first air suspension according to the present disclosure. A first shock absorber 210 and a first air spring 220 are provided in the first air suspension. The upper end of the first shock absorber is connected to the vehicle body, and the lower end is connected to the wheel.

[0036] It should be noted that the vehicle may have multiple air suspensions, and the first air suspension is any one of the multiple air suspensions of the vehicle, and no limitation is made here.

[0037] Among them, the controller identifies that the first air suspension enters the first lifting scenario according to the vehicle condition information and / or the received user instruction information, and sends a first adjustment instruction to the first air suspension. The first adjustment instruction includes a first damping force adjustment instruction for the first shock absorber and a first stretching force adjustment instruction for the first air spring.

[0038] The first shock absorber is configured to obtain the first damping force in the first damping force adjustment instruction and increase its current second damping force to the first damping force.

[0039] The first air spring is configured to obtain the first stretching force in the first stretching force adjustment instruction and reduce its current second stretching force to the first stretching force, where the first stretching force is less than or equal to the first damping force.

[0040] It should be noted that the first damping force and the first stretching force are determined by the controller according to the vehicle condition information and / or the received instruction information to identify the position to which the first air suspension needs to be adjusted.

[0041] It should be noted that the first lifting scenario in the embodiments of the present disclosure is the scenario where the first air suspension needs to be lifted. This first lifting scenario may need to be carried out in various situations. For example, when the wheel corresponding to the first air suspension needs to be replaced, when the first air suspension needs to be repaired, etc.

[0042] In the embodiments of the present disclosure, the controller may be an electronic control unit (ECU). The ECU collects the vehicle height, speed, steering wheel angle, brake wheel cylinder pressure, driving mode, etc. as input signals through sensors and the CAN bus. After algorithm processing, it obtains the control signal that makes the system control performance optimal, and controls the on / off time or current magnitude of the solenoid valve via the drive circuit, thereby adjusting the inflation and deflation of the air spring or adjusting the damping force of the shock absorber to achieve the effect of adjusting the suspension stiffness and damping.

[0043] It should be noted that the instruction information may be issued by an operator or generated and issued by a remote control device according to the vehicle condition information reported by the vehicle. The remote control device may be a vehicle server, a remote control computer, etc. It should be noted that the instruction information may include various information, which is not limited here. For example, it may include the duration that needs to be adjusted and the start time of the adjustment, etc.

[0044] In the embodiments of the present disclosure, the system further includes a second air suspension 300. The structure of the second air suspension may refer to Figure 3 as shown in Figure 3 which is a schematic structural diagram of a second air suspension of the present disclosure. A second shock absorber 310 and a second air spring 320 are provided in the second air suspension. The upper end of the second shock absorber is connected to the vehicle body, and the lower end is connected to the wheel.

[0045] In the current technology, when the vehicle body is being lifted by a lift, the vehicle is considered to have its wheels moving downward, and the air springs will adjust their heights, resulting in incorrect inflation and deflation. At the same time, after the lift is removed from the vehicle, the vehicle height will be abnormal and cannot well meet the height requirements. Therefore, during the upward movement of the first air suspension, the controller can send a lowering adjustment command to the second air suspension to avoid the above situation.

[0046] Among them, when the controller recognizes that the second air suspension needs to be lowered, it sends a second adjustment command to the second air suspension. The second adjustment command includes a second damping force adjustment command for the second shock absorber and a second stretching force adjustment command for the second air spring. It should be noted that the second damping force adjustment command is an instruction for the controller to control the second shock absorber of the second air suspension to make adjustments. The second damping force adjustment command includes the third damping force to which the second shock absorber needs to be adjusted. The second stretching force adjustment command is an instruction for the controller to control the second air spring of the second air suspension to make adjustments. The second stretching force adjustment command includes the third stretching force to which the second air spring needs to be adjusted.

[0047] The second shock absorber is used to obtain the third damping force in the second damping force adjustment command and reduce its current fourth damping force to the third damping force.

[0048] The second air spring is used to obtain the third stretching force in the second stretching force adjustment command and reduce its current fourth stretching force to the third stretching force.

[0049] It should be noted that the third damping force and the third stretching force are determined by the controller according to the working condition information of the vehicle and / or the received instruction information to identify the position to which the second air suspension needs to be adjusted.

[0050] In the embodiment of the present disclosure, the system further includes a third air suspension and a fourth air suspension. A third shock absorber and a third air spring are provided in the third air suspension, and a fourth shock absorber and a fourth air spring are provided in the fourth air suspension. It should be noted that the structures of the third air suspension and the fourth air suspension are the same as those of the first air suspension.

[0051] As Figure 4 shown, the first air suspension and the second air suspension are in a diagonal relationship, and the third air suspension and the fourth air suspension are in a diagonal relationship.

[0052] When the controller recognizes that the first air suspension enters the first lifting scenario, the third air suspension and the fourth air suspension need to stop operating, and the controller sends a first stop operation command to the third air suspension and the fourth air suspension. Among them, the first stop operation command includes a first shock absorber stop operation command and a first air spring stop operation command.

[0053] The third shock absorber and the fourth shock absorber stop adjusting the damping force and keep their own damping force unchanged based on the received first shock absorber stop operation instruction.

[0054] The third air spring and the fourth air spring stop the inflation and deflation operation and keep their own extension force unchanged based on the received first air spring stop operation instruction.

[0055] In the embodiment of the present disclosure, when the first air suspension enters the first lifting scenario, in order to ensure the balance of the vehicle body and the lifting effect of the first air suspension, the third shock absorber, the fourth shock absorber, the third air spring and the fourth air spring need to maintain the stopped operation state, that is, keep their own damping force unchanged and keep their own extension force unchanged.

[0056] For example, in a possible scenario, if it is necessary to replace the left front tire, the operator can control the controller, or the controller automatically recognizes that the first air suspension enters the first lifting scenario, and the controller issues an instruction to adjust the second damping force of the first shock absorber of the first air suspension corresponding to the left front wheel to the first damping force. The first damping force can enable the damping of the first shock absorber to well offset the first extension force of the first air spring during the lifting process by the jack. The controller issues an instruction to make the damping force of the first shock absorber greater than the first extension force, so that the wheel can leave the ground well, reducing the lifting displacement of the lift. However, during the lifting process, the lift needs to bear 1 / 4 of the vehicle weight. To reduce the lifting load of the lift, the controller needs to issue an instruction to execute deflation of the second air spring of the second suspension system and minimize the damping of the second shock absorber. In this way, a torque can be realized along the diagonal of the vehicle body during the lifting process, and the lift can very easily lift the left front body of the vehicle. At the same time, the third shock absorber and the fourth shock absorber maintain their height unchanged, so as to ensure the balance of the vehicle. Thereby improving the lifting efficiency and saving manpower and physical strength, and realizing rapid replacement.

[0057] It should be noted that the system further includes a sensor assembly, wherein the sensor assembly is used to identify the working condition information of the vehicle and transmit the working condition information to the controller.

[0058] In another possible implementation manner of the present disclosure, the controller is further configured to: when it recognizes that the vehicle enters the second lifting scenario, send a second stop operation instruction to the first air suspension, the second air suspension, the third air suspension and the fourth air suspension. The second stop operation instruction includes a second shock absorber stop operation instruction and a second air spring stop operation instruction.

[0059] The first shock absorber, the second shock absorber, the third shock absorber and the fourth shock absorber stop adjusting the damping force and keep their own damping force unchanged based on the received second shock absorber stop operation instruction.

[0060] The first air spring, the second air spring, the third air spring, and the fourth air spring stop the air charging and discharging operation and maintain their own tensile force unchanged based on the received second air spring stop operation instruction.

[0061] It should be noted that the second lifting scenario is the scenario where the first air suspension, the second air suspension, the third air suspension, and the fourth air suspension need to be lifted. In this scenario, the first air suspension, the second air suspension, the third air suspension, and the fourth air suspension all remain in the stopped operation state, and only the jack is used to lift the first air suspension, the second air suspension, the third air suspension, and the fourth air suspension.

[0062] Figure 5 It is a schematic flowchart of a vehicle lifting method based on an air suspension according to an embodiment of the present disclosure. As Figure 5 shown, the method includes:

[0063] S501, obtain the working condition information of the vehicle and / or the received user instruction information, and identify whether the vehicle enters the first lifting scenario according to the working condition information and / or the user instruction information.

[0064] For the specific implementation method of this step, reference can be made to the content in the above embodiments, which will not be elaborated here.

[0065] S502, in response to identifying that the vehicle enters the first lifting scenario, obtain the first adjustment instruction of the first air suspension of the vehicle, where the first adjustment instruction includes a first damping force adjustment instruction and a first air spring adjustment instruction.

[0067] S503, based on the first damping force in the first damping force adjustment instruction, control the first shock absorber in the first air suspension to increase from the current second damping force to the first damping force, and based on the first tensile force in the first tensile force adjustment instruction, control the first air spring in the first air suspension to decrease from the current second tensile force to the first tensile force, so as to lift the first air suspension end of the vehicle, where the first tensile force is less than or equal to the first damping force.

[0068] In an embodiment of the present disclosure, first, the operating condition information of the vehicle and / or the received user instruction information are obtained, and it is identified whether the vehicle enters the first lifting scenario according to the operating condition information and / or the user instruction information. Then, in response to identifying that the vehicle enters the first lifting scenario, a first adjustment instruction for the first air suspension of the vehicle is obtained, where the first adjustment instruction includes a first damping force adjustment instruction and a first air spring adjustment instruction. Finally, based on the first damping force in the first damping force adjustment instruction, the first shock absorber in the first air suspension is controlled to increase from the current second damping force to the first damping force, and based on the first extension force in the first extension force adjustment instruction, the first air spring in the first air suspension is controlled to decrease from the current second extension force to the first extension force, so as to lift the first air suspension end of the vehicle, where the first extension force is less than or equal to the first damping force. Thus, after identifying that the vehicle enters the first lifting scenario, the first shock absorber and the first air spring of the first air suspension end of the vehicle can be adjusted to lift the first air suspension end of the vehicle, thereby achieving rapid lifting of the first air suspension end and improving the efficiency and stability of lifting the first air suspension end.

[0069] In an embodiment of the present disclosure, in response to identifying that the vehicle enters the first lifting scenario, a second adjustment instruction for the second air suspension of the vehicle is obtained, where the second adjustment instruction includes a second damping force adjustment instruction and a second air spring adjustment instruction. Based on the second damping force adjustment instruction, the second shock absorber in the second air suspension is controlled to decrease from the current third damping force to the fourth damping force, and based on the second extension force adjustment instruction, the second air spring in the second air suspension is controlled to decrease from the current third extension force to the fourth extension force, so as to lower the second air suspension end of the vehicle.

[0070] In an embodiment of the present disclosure, in response to identifying that the vehicle enters the first lifting scenario, a first stop operation instruction for the third air suspension and the fourth air suspension of the vehicle is obtained, and the first stop operation instruction includes a first shock absorber stop operation instruction and a first air spring stop operation instruction. Based on the first shock absorber stop operation instruction, the third shock absorber and the fourth shock absorber in the third air suspension and the fourth air suspension are controlled to stop damping force adjustment and keep their own damping forces unchanged. Finally, based on the first air spring stop operation instruction, the third air spring and the fourth air spring in the third air suspension and the fourth air suspension are controlled to stop air charging and discharging operations and keep their own extension forces unchanged.

[0071] In one embodiment of the present disclosure, it is recognized whether the vehicle enters the second lifting scenario. In response to recognizing that the vehicle enters the second lifting scenario, a second stop operation instruction for the first air suspension, the second air suspension, the third air suspension, and the fourth air suspension of the vehicle is obtained. The second stop operation instruction includes a second shock absorber stop operation instruction and a second air spring stop operation instruction. Then, based on the second shock absorber stop operation instruction, the first shock absorber, the second shock absorber, the third shock absorber, and the fourth shock absorber in the first air suspension, the second air suspension, the third air suspension, and the fourth air suspension are controlled to stop damping force adjustment and maintain their own damping force unchanged. Finally, based on the second air spring stop operation instruction, the first air spring, the second air spring, the third air spring, and the fourth air spring in the first air suspension, the second air suspension, the third air suspension, and the fourth air suspension are controlled to stop air charging and discharging operations and maintain their own stretching force unchanged.

[0072] In one embodiment of the present disclosure, the first lifting scenario is a scenario where the first air suspension end is lifted, and the second lifting scenario is a scenario where the first air suspension, the second air suspension, the third air suspension, and the fourth air suspension are lifted.

[0073] Corresponding to the vehicle lifting method based on air suspension provided in the above several embodiments, one embodiment of the present disclosure also provides a vehicle lifting device based on air suspension. Since the vehicle lifting device based on air suspension provided in the embodiments of the present disclosure corresponds to the vehicle lifting method based on air suspension provided in the above several embodiments, the implementation manners of the above vehicle lifting method based on air suspension are also applicable to the vehicle lifting device based on air suspension provided in the embodiments of the present disclosure, and will not be described in detail in the following embodiments.

[0074] Figure 6 is a schematic diagram of a vehicle lifting device based on air suspension according to an embodiment of the present disclosure. As Figure 6 shown, the vehicle lifting device 600 based on air suspension includes: an acquisition module 610, an acquisition module 620, and a lifting module 630.

[0075] Among them, the acquisition module 610 is configured to obtain the working condition information of the vehicle and / or the received user instruction information, and identify whether the vehicle enters the first lifting scenario according to the working condition information and / or the user instruction information.

[0076] The acquisition module 620 is configured to obtain a first adjustment instruction for the first air suspension of the vehicle in response to recognizing that the vehicle enters the first lifting scenario. The first adjustment instruction includes a first damping force adjustment instruction and a first air spring adjustment instruction.

[0077] The lifting module 630 is configured to control the first shock absorber in the first air suspension to increase from the current second damping force to the first damping force based on the first damping force in the first damping force adjustment instruction, and control the first air spring in the first air suspension to decrease from the current second extension force to the first extension force based on the first extension force in the first extension force adjustment instruction, so as to lift the first air suspension end of the vehicle, where the first extension force is less than or equal to the first damping force.

[0078] Thus, after it is recognized that the vehicle enters the first lifting scenario, the first shock absorber and the first air spring of the first air suspension end of the vehicle can be adjusted, and it can be realized that the first shock absorber damping of the first shock absorber cancels the first extension force of the first air spring during the lifting process of the lift, so as to realize the rapid lifting of the first air suspension end and improve the efficiency and stability of lifting the first air suspension end.
