DETAILED DESCRIPTION
[0021] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0022] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, combined, or partially merged, so the actual execution order may vary depending on the actual situation.
[0023] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.
[0024] In a first aspect, an embodiment of the present application provides an automated durability testing method for an electric rearview mirror, the method comprising the following steps: Create test cases that include the adjustment direction, adjustment distance, and number of adjustments of the electric rearview mirror, and generate adjustment instructions based on the test cases.
[0025] An adjustment instruction is sent to the electric rearview mirror through the adjustment device, and the adjustment instruction includes an adjustment direction and an adjustment distance; the adjustment device controls the movement of the electric rearview mirror according to the adjustment instruction.
[0026] Obtaining displacement information of the electric rearview mirror corresponding to the adjustment instruction, the displacement information including the moving position and moving direction of the electric rearview mirror; judging whether the electric rearview mirror can be adjusted based on the moving position; judging whether the electric rearview mirror moves in the above adjustment direction based on the moving direction; Regularly monitor the movement position of the electric rearview mirror, and determine whether the electric rearview mirror continues to move in the adjustment direction based on the movement position of the electric rearview mirror at different times.
[0027] After the electric rearview mirror has finished moving, determine whether the adjustment distance of the electric rearview mirror meets the requirements based on the initial position and final position of the electric rearview mirror.
[0028] From this we can see that: This application uses an adjustment device to automatically control the movement of the electric rearview mirror and automatically determines whether the electric rearview mirror meets the standards based on feedback information from the electric rearview mirror (such as displacement information, movement position during movement, and final position after movement). Therefore, compared with the existing technology of manually operating the rearview mirror and performing comparisons, this application can automatically perform multiple electric rearview mirror durability tests based on this method, significantly improving test accuracy and efficiency.
[0029] At the same time, this application determines whether the electric rearview mirror can be adjusted by its moving position, whether the adjustment direction meets the expectations by its moving direction and position during the movement, and whether the adjustment distance meets the expectations by its final position after the movement. Therefore, this application can determine whether the corresponding test function has passed based on different information of the electric rearview mirror, and if it fails, it can directly and accurately locate the reason for the failure.
[0030] In summary, the present application can automatically and accurately realize the detection of electric rearview mirrors.
[0031] In one embodiment, the method further includes the following steps: monitoring a fault signal from the adjustment device in real time, and determining whether the adjustment device has failed based on the fault signal. The principle behind this implementation is that if the adjustment device fails, the electric rearview mirror will inevitably be unable to adjust. Therefore, if the adjustment device fails, no further testing is required. This further clarifies the cause of the test failure and improves test efficiency.
[0032] Furthermore, the above method specifically includes the following steps: Only when the electric rearview mirror can be adjusted, the movement direction is used to determine whether the electric rearview mirror moves in the above adjustment direction; because if the electric rearview mirror cannot be adjusted, the problem has been located, and subsequent tests will inevitably fail at this time, that is, no subsequent tests are required.
[0033] Only when the electric rearview mirror can move in the above-mentioned adjustment direction, the movement position of the electric rearview mirror should be monitored regularly. If the electric rearview mirror cannot move in the adjustment direction, the problem has been located and the subsequent test will inevitably fail, that is, no subsequent test is required.
[0034] When the electric rearview mirror can continue to move in the adjustment direction, wait until the electric rearview mirror has finished moving to determine whether the adjustment distance of the electric rearview mirror meets the requirements; because if the electric rearview mirror cannot continue to move in the adjustment direction, the problem has been located and subsequent tests will inevitably fail at this time, that is, no subsequent tests are required.
[0035] When a fault signal from the adjustment device is received, the test of the electric rearview mirror is stopped because the problem is now a fault in the adjustment device and the test of the electric rearview mirror cannot be performed.
[0036] This application further clearly locates the source of the problem through the above-mentioned test judgment sequence logic, thereby further improving the test efficiency.
[0037] In one embodiment, the adjustment distance in the above method is reflected (defined) by the adjustment time, and the adjustment time is the maximum time required for the adjustment distance to move (that is, the time required for the electric rearview mirror to definitely "complete" the adjustment distance). This is because during the test, only the adjustment time of the electric rearview mirror can be controlled, and the movement distance of the electric rearview mirror cannot be accurately controlled. In addition, the movement distance of the electric rearview mirror is also needed to determine whether the electric rearview mirror meets the requirements in terms of adjustment distance.
[0038] In one embodiment, the method further includes the following steps before monitoring the moving position of the electric rearview mirror: defining the end point value of each adjustment direction; on this basis, the process of judging whether the electric rearview mirror continues to move in the adjustment direction according to the moving position of the electric rearview mirror at different times in the above method includes: judging whether the moving position of the electric rearview mirror received later is closer to the end point value of the current adjustment direction than the moving position of the electric rearview mirror received earlier (generally adjacent); if so, confirming that the electric rearview mirror continues to move in the adjustment direction; otherwise, confirming that the electric rearview mirror does not continue to move in the adjustment direction.
[0039] For example, for the left and right directions, the end point value of the left direction is 0, and the end point value of the right direction is 100. When the adjustment direction is left and the initial position of the electric rearview mirror is 50, if the adjacent moving positions of the electric rearview mirror received in chronological order are 48 and 45, it can be confirmed that the electric rearview mirror is continuing to move to the left.
[0040] In one embodiment, the method for determining whether the electric rearview mirror in the above method can be adjusted is: the moving position of the electric rearview mirror is different from the initial position; the method for determining whether the electric rearview mirror moves in the above adjustment direction is: the moving direction of the electric rearview mirror is the same as the adjustment direction; the method for determining whether the adjustment distance of the electric rearview mirror meets the requirements is: the moving distance calculated based on the initial position and final position of the electric rearview mirror is the same as the adjustment distance.
[0041] In one embodiment, the regulating device in the above method is a car controller, that is, the present application directly reuses the functions of the car controller to control the electric rearview mirror without adding additional components.
[0042] In one embodiment, the position of the electric rearview mirror in the above method is obtained based on a displacement sensor originally used for the electric rearview mirror, and the moving direction of the electric rearview mirror is determined based on the position of the electric rearview mirror after movement.
[0043] From this, it can be seen that the present application directly reuses the displacement sensor of the electric rearview mirror to implement the above process, and in actual use, the corresponding position acquisition tool can also be used according to different needs; at the same time, the display method of the position of the above-mentioned electric rearview mirror is also the same as that of the displacement sensor, for example, through percentage, coordinates, etc., and the display method of the position of the electric rearview mirror can also be adjusted during actual use.
[0044] See below Figure 1 As shown, the complete execution process of the above method is described in time sequence through a specific embodiment.
[0045] S1: Create a test case based on the adjustment direction, adjustment distance, and number of adjustments of the electric rearview mirror to be tested. The following uses left adjustment as an example to further illustrate this method.
[0046] S2: Based on the test case, a left adjustment command is generated. This command includes the adjustment direction and distance. The vehicle controller sends the left adjustment command to the electric rearview mirror. Specifically, the command contains the CAN ID (the number of the vehicle controller that controls the electric rearview mirror): 745, and the Req_Data: 2F 55 82 03 04 (the adjustment command data code). The vehicle controller controls the movement of the electric rearview mirror according to the left adjustment command.
[0047] S3: Get the electric rearview mirror displacement information returned by the vehicle controller. The displacement information includes the moving position and moving direction of the electric rearview mirror. Specifically, Res_Id (the reply number of the vehicle controller): 7C5, Rsq Data (displacement information data code): 6F 55 82 03 04.
[0048] S4: Determine whether the moving position is the same as the initial position. If so, it means that the electric rearview mirror has not moved, that is, it cannot be adjusted, and the process ends. Otherwise, subsequent tests can be performed and the process goes to S5.
[0049] S5: Determine whether the moving direction is the same as the adjustment direction. If so, it means that the electric rearview mirror can be adjusted and the adjustment direction is correct, and subsequent tests can be performed, and go to S6; otherwise, it means that the electric rearview mirror cannot move in the adjustment direction, and the process ends.
[0050] S6: Regularly monitor the movement position of the electric rearview mirror through the monitoring link (CAN ID: 0x3E7). Based on the movement position of the electric rearview mirror at different times, determine whether the electric rearview mirror continues to move in the adjustment direction. If so, it means that the electric rearview mirror can be continuously adjusted correctly, and subsequent tests can be performed, and go to S7. Otherwise, it means that the electric rearview mirror cannot be continuously adjusted correctly, and the process ends.
[0051] S7: After the electric rearview mirror has finished moving, the moving distance is calculated based on the initial position and final position of the electric rearview mirror; whether the moving distance is the same as the adjustment distance is determined; if so, it is determined that the adjustment distance of the electric rearview mirror meets the requirements, and the process ends; otherwise, it is determined that the adjustment distance of the electric rearview mirror does not meet the requirements, and the process ends.
[0052] During the execution of S3 to S7, the fault signal of the regulating device is monitored in real time, and the test is stopped when the fault signal of the regulating device is received.
[0053] On the second aspect, an embodiment of the present application also provides an automated durability testing system for an electric rearview mirror, which includes a server (which can be set up in the cloud), a data acquisition device and a vehicle-side control device (such as an on-board diagnostic system On-Board Diagnostics, OBD).

[0055] The data acquisition device is used to: convert the test case into the above adjustment instructions and send them to the vehicle-side control device; upload the information returned by the vehicle-side control device to the server; The vehicle-side control device includes a regulating device, which is used to: (1) Sending adjustment instructions to the electric rearview mirror through the adjustment device, and the adjustment device controls the movement of the electric rearview mirror according to the adjustment instructions; (2) Obtaining the displacement information of the electric rearview mirror corresponding to the adjustment instruction and uploading it to the data acquisition device; monitoring the moving position of the electric rearview mirror during the movement process, the final position after the movement is completed, and the fault signal of the adjustment device, and uploading the moving position, the initial position, the final position, and the fault signal of the electric rearview mirror to the data acquisition device.
