Description

Technical Field

[0002] The vehicle suspension is a structure connecting the car body and wheels. Its main function is to absorb the impacts and vibrations experienced by the wheels during driving, ensuring a smooth ride. The toe angle and camber angle are important design parameters for the suspension. The toe angle is the angle between the front of the wheel and the vehicle's centerline when viewed from directly above the car. The camber angle is the angle between the plane containing the wheel and the vertical plane. Proper toe and camber angles improve vehicle stability and reduce tire wear. Before leaving the factory, the vehicle suspension needs to be adjusted to achieve optimal toe and camber angles.

[0003] Currently, most methods involve manually adjusting the toe angle and camber angle, which is difficult to adjust and makes it hard to properly match the toe angle and camber angle, thus affecting vehicle performance. Summary of the Invention

[0048] This application also provides a vehicle suspension adjustment control method 40. The vehicle suspension adjustment control method 40 is used to adjust the toe angle and camber angle of the vehicle suspension. A vehicle suspension adjustment control system 11 is used to execute the vehicle suspension adjustment control method 40. The vehicle suspension adjustment control method 40 includes: acquiring the wheel speed of the wheels of the vehicle 10; if the wheel speed is not zero, requesting to receive the toe angle and camber angle; if the wheel speed is zero, stopping the adjustment of the toe angle and camber angle. In some embodiments, when adjusting the toe angle and camber angle of the vehicle suspension, the vehicle suspension adjustment control system 11 sends a start adjustment command to the four-wheel alignment system control module 31. The four-wheel alignment system control module 31 controls the hub module 32 to drive the wheels to rotate, and the vehicle suspension adjustment control system 11 controls the wheel speed sensor 14 to detect the wheel speed signal. If the wheel speed sensor 14 can detect the wheel speed, and the wheel speed acquired by the vehicle suspension adjustment control system 11 is not zero, it indicates that the wheel is rotating normally. At this time, the vehicle suspension adjustment control system 11 sends a request to the four-wheel alignment system control module 31 to receive the toe angle and camber angle. The four-wheel alignment system control module 31 controls the detection module 33 to detect the toe angle and camber angle of the vehicle 10 and transmits them to the vehicle suspension adjustment control system 11. If the wheel speed sensor 14 cannot detect the wheel speed, the wheel speed obtained by the vehicle suspension adjustment control system 11 is zero, indicating abnormal wheel rotation. At this time, the vehicle suspension adjustment control system 11 stops adjusting the toe angle and camber angle and sends a stop adjustment command to the four-wheel alignment system control module 31. The four-wheel alignment system control module 31 controls the hub module 32 of the four-wheel alignment system 30 to stop driving the wheels to avoid safety risks and damage to the vehicle's braking system components.

[0049] Figure 2 The diagram shown is a flowchart of one embodiment of the vehicle suspension adjustment control method 40 of this application. (In conjunction with...) Figure 1 and Figure 2The vehicle suspension adjustment control method 40 includes steps 41, 42, 43, and 44. In step 41, a pre-configured matching range for the toe angle and camber angle of the vehicle 10, and the corresponding priority, are obtained. The priority includes a highest priority, a lowest priority, and several intermediate priorities. In some embodiments, the vehicle suspension adjustment control system 11 pre-stores the matching range for the toe angle and camber angle of the vehicle 10, and the corresponding priority. The priority includes several priorities from the highest to the lowest priority. When adjusting the vehicle suspension, the toe angle and camber angle of the vehicle 10 need to be matched to obtain better performance. The vehicle 10 may have different performance within different matching ranges for its toe angle and camber angle. Therefore, different matching ranges correspond to different priorities. When the vehicle 10 has optimal performance, the priority corresponding to the matching range where the toe angle and camber angle are located is the highest priority. When the vehicle 10 has the lowest permissible performance, the priority corresponding to the matching range where the toe angle and camber angle are located is the lowest priority. When vehicle 10 has different intermediate performance levels, the matching intervals for toe angle and camber angle correspond to different intermediate priorities. When adjusting the vehicle suspension, the vehicle suspension adjustment control system 11 acquires the pre-configured matching intervals for toe angle and camber angle of vehicle 10, as well as the priorities corresponding to the matching intervals.

[0050] In some embodiments, step 41 includes: obtaining the matching intervals of the toe angle and camber angle of the vehicle corresponding to the vehicle model. The vehicle suspension adjustment control system 11 obtains the matching intervals of the toe angle and camber angle of the vehicle corresponding to the vehicle signal, and the priority corresponding to the matching intervals, based on the vehicle model to be adjusted. Different vehicle models have different pre-stored matching intervals of toe angle and camber angle. The vehicle suspension adjustment control system 11 can obtain different matching intervals of toe angle and camber angle based on the vehicle model, thus broadening the applicability of the vehicle suspension adjustment control method 40.

[0051] In step 42, the toe angle and camber angle are adjusted according to the matching range corresponding to the highest priority. The vehicle suspension adjustment control system 11 adjusts the toe angle and camber angle to the corresponding matching range according to the obtained matching range corresponding to the highest priority. To achieve optimal vehicle performance, the toe angle and camber angle are first adjusted according to the matching range corresponding to the highest priority.

[0052] In some embodiments, step 42 includes: controlling the toe angle adjustment mechanism 12 to adjust the toe angle according to the matching interval corresponding to the highest priority, and controlling the camber angle adjustment mechanism 13 to adjust the camber angle. The vehicle suspension adjustment control system 11 controls the toe angle adjustment mechanism 12 to adjust the toe angle and the camber angle adjustment mechanism 13 to adjust the camber angle according to the matching interval corresponding to the highest priority. In some embodiments, the toe angle adjustment mechanism 12 is controlled to adjust the toe angle first, and then the camber angle adjustment mechanism 13 is controlled to adjust the camber angle. In other embodiments, the camber angle adjustment mechanism 13 is controlled to adjust the camber angle first, and then the toe angle adjustment mechanism 12 is controlled to adjust the toe angle. In other embodiments, the toe angle adjustment mechanism 12 is controlled to adjust the toe angle, and the camber angle adjustment mechanism 13 is controlled to adjust the camber angle simultaneously.

[0053] In step 43, if the toe angle and camber angle cannot be adjusted to the matching range corresponding to the highest priority, the toe angle and camber angle are adjusted according to the matching range corresponding to the next lower priority. When adjusting the vehicle suspension, the vehicle suspension adjustment control system 11 receives the toe angle and camber angle detected by the detection module 33 sent by the four-wheel alignment system control module 31. If the toe angle and camber angle cannot be adjusted to the matching range corresponding to the highest priority, the vehicle suspension adjustment control system 11 adjusts the toe angle and camber angle according to the matching range corresponding to the next lower priority.

[0054] In step 44, if the toe angle and camber angle cannot be adjusted to the matching range corresponding to the next lower priority of the highest priority, the process continues in descending order of priority. If the toe angle and camber angle cannot be adjusted to the matching range corresponding to the next lower priority of the highest priority, the vehicle suspension adjustment control system 11 adjusts the toe angle and camber angle according to the matching range corresponding to the next lower priority. If the adjustment still fails, the vehicle suspension adjustment control system 11 adjusts the toe angle and camber angle according to the matching range corresponding to the respective priorities, in descending order of priority.

[0055] In some embodiments, the toe angle and camber angle of the vehicle 10 are automatically adjusted in descending order of priority according to the pre-configured matching range and priority of the toe angle and camber angle, so that the two can reach the ideal matching range as much as possible, which can better adjust the wheel alignment and improve the performance of the vehicle 10.

[0056] Optionally, the vehicle suspension adjustment control method 40 includes: acquiring the current toe angle and current camber angle of the vehicle; if, within a preset time period, the matching intervals corresponding to the current toe angle and the current camber angle are consistent with the matching intervals corresponding to the current adjustment priority, a first reminder signal indicating successful adjustment is generated. During the vehicle suspension adjustment process, the toe angle of the vehicle 10 is the current toe angle, and the camber angle of the vehicle 10 is the current camber angle. The preset time period is a pre-set vehicle suspension adjustment time period. Within the preset time period, the vehicle suspension adjustment control system 11 acquires the current toe angle and current camber angle data detected by the detection module 33, and compares whether the matching intervals corresponding to the current toe angle and the current camber angle are consistent with the matching intervals corresponding to the current adjustment priority. If they are consistent, the vehicle suspension adjustment control system 11 generates a first reminder signal indicating successful adjustment. In some embodiments, the vehicle suspension adjustment control system 11 sends the first reminder signal to the speaker 15, and the speaker 15 converts the first reminder signal into a voice signal output to remind the user that the adjustment at the current priority is successful. In some embodiments, the vehicle suspension adjustment control system 11 sends a first reminder signal to the four-wheel alignment system control module 31, the four-wheel alignment system control module 31 sends a first reminder signal to the display module 34, and the display module 34 converts the first reminder signal into text or image information and displays it to remind the user that the current priority adjustment has been successful.

[0057] Optionally, the vehicle suspension adjustment control method 40 includes: if, within the preset time period, the matching intervals corresponding to the current toe angle and the current camber angle are inconsistent with the matching interval corresponding to the current adjustment priority, a second reminder signal indicating adjustment failure at the current adjustment priority is generated. Within the preset time period, the vehicle suspension adjustment control system 11 acquires the current toe angle and current camber angle data detected by the detection module 33, and compares whether the matching intervals corresponding to the current toe angle and the current camber angle are consistent with the matching interval corresponding to the current adjustment priority. If they are inconsistent, the vehicle suspension adjustment control system 11 generates a second reminder signal indicating adjustment failure. In some embodiments, the vehicle suspension adjustment control system 11 sends the second reminder signal to the speaker 15, and the speaker 15 converts the second reminder signal into a voice signal for output, reminding the user that the adjustment has failed at the current priority. In some embodiments, the vehicle suspension adjustment control system 11 sends the second reminder signal to the four-wheel alignment system control module 31, and the four-wheel alignment system control module 31 sends the second reminder signal to the display module 34, and the display module 34 converts the second reminder signal into text or image information for display, reminding the user that the adjustment has failed at the current priority.

[0058] The following example illustrates the vehicle suspension adjustment control method 40. Table 1 shows the matching ranges of the toe angle and camber angle of the vehicle 10 obtained by the vehicle suspension adjustment control system 11, and the corresponding priorities of the matching ranges. The priorities, from highest to lowest, are C1, C2, C3, C4, and C5. The toe angle ranges are A1 to A8. The camber angle ranges are B1 to B8.

[0059] Serial Number Toe angle range Lap angle range Matching status Priority 1 A1~A2 B1~B2 Matching interval 1 C1 2 A3~A4 B3~B4 Matching interval 2 C2 3 A5~A6 B5~B6 Matching interval 3 C3 4 A7~A8 B7~B8 Matching interval 4 C4 5 A1~A8 B1~B8 Matching interval 5 C5

[0060] Table 1

[0061] First, the toe angle and camber angle are adjusted according to the matching interval 1 corresponding to the highest priority C1. The toe angle corresponding to matching interval 1 is A1~A2, and the camber angle is B1~B2. The vehicle suspension adjustment control system 11 adjusts the toe angle and camber angle of the vehicle 10 and obtains the current toe angle and current camber angle of the vehicle 10 during the adjustment process. If the current toe angle is within the interval A1~A2 and the current camber angle is within the interval B1~B2, it indicates that the adjustment at priority C1 is successful. The vehicle suspension adjustment control system 11 generates a first reminder signal indicating successful adjustment. If, within a preset time period, the current toe angle cannot be within the interval A1~A2, or the current camber angle cannot be within the interval B1~B2, it indicates that the adjustment at priority C1 fails. The vehicle suspension adjustment control system 11 generates a second reminder signal indicating adjustment failure. After the adjustment at priority C1 fails, the vehicle suspension adjustment control system 11 adjusts the toe angle and camber angle according to the matching interval 2 corresponding to priority C2. Matching interval 2 corresponds to toe angles of A3-A4 and camber angles of B3-B4. If the current toe angle is within the A3-A4 interval and the current camber angle is within the B3-B4 interval, it indicates successful adjustment at priority C2. The vehicle suspension adjustment control system 11 generates a first reminder signal indicating successful adjustment. If, within a preset time period, the current toe angle cannot be within the A3-A4 interval, or the current camber angle cannot be within the B3-B4 interval, it indicates failed adjustment at priority C2. The vehicle suspension adjustment control system 11 generates a second reminder signal indicating failed adjustment. After failure of priority C2 adjustment, the vehicle suspension adjustment control system 11 adjusts the toe angle and camber angle according to matching interval 2 corresponding to priority C3, and so on, until adjusting the toe angle and camber angle according to matching interval 5 corresponding to the lowest priority C5.
