This requires troubleshooting the entire system chain when locating problems. This fragmented testing approach struggles to address the challenges posed by the numerous functions, complex components, and extensive interactions of exterior rearview mirror systems. Consequently, the testing lacks systematicity and hierarchy, severely impacting efficiency and making the process cumbersome. Therefore, there is an urgent need to propose a systematic exterior rearview mirror testing method aimed at improving testing efficiency. Summary of the Invention

[0006] A control feedback system for a crab-like driving function according to an embodiment of the present invention has at least the following beneficial effects: This invention proposes a systematic testing method for exterior rearview mirrors through logical analysis and sequential arrangement. By arranging a logical and sequential systematic comprehensive testing order, basic function tests, enable switch tests, and enable function tests are performed in sequence.

Under systematic testing, problems can be investigated through multiple logical paths, increasing the efficiency of testing and problem solving.

[0007] According to some embodiments of the present invention, the basic function test, the enable switch test, and the enable function test are performed sequentially. If any one of the basic function test, the enable switch test, and the enable function test fails, the technical test is terminated, and troubleshooting is performed based on the function corresponding to the failed test.

[0008] According to some embodiments of the present invention, the exterior rearview mirror is controlled by an adjustment motor and a folding motor, and basic functional tests are performed on the exterior rearview mirror, including: To test the position adjustment function of the exterior rearview mirrors, the virtual buttons integrated into the vehicle's central control screen are operated. The virtual buttons send the instructions to the mechanical adjustment buttons integrated into the vehicle's steering wheel. The mechanical adjustment buttons feed back the manual operation as an adjustment signal and transmit it to the corresponding drive motor of the exterior rearview mirror. The adjustment motor completes the position adjustment control based on the adjustment signal. The electric folding function of the exterior rearview mirrors was tested. The virtual buttons integrated into the vehicle's central control screen were operated. The folding motor directly received the status signal from the virtual buttons and drove the exterior rearview mirrors to fold based on the status signal.

[0009] According to some embodiments of the present invention, basic functional tests are performed on the exterior rearview mirror, including: Test whether the regulating motor and the folding motor respond to control commands in a timely manner; Test whether the driving of the regulating motor and the folding motor is continuous; Test whether the regulating motor and the folding motor can provide real-time feedback on the current position; Test whether the regulating motor and the folding motor can accurately detect stall.

[0010] According to some embodiments of the present invention, if the basic function test passes, an enable switch test is performed on the exterior rearview mirror, including: Test the automatic tilt-down enable switch of the exterior rearview mirror when reversing, and observe whether the enable signal controlling the automatic tilt-down of the exterior rearview mirror can perform the setting and resetting actions as the switch is turned on and off, and whether there is any rebound. Test the automatic folding enable switch when locking the car, that is, observe whether the enable signal in the exterior rearview mirror software that controls the automatic folding when locking the car can perform the setting and resetting actions as the switch is opened and closed, and whether there is any rebound.

[0011] According to some embodiments of the present invention, if the enable switch test passes, an enable function test is performed on the exterior rearview mirror, including: To test the automatic tilt-down function of the exterior rearview mirrors, turn on the automatic tilt-down enable switch, shift the vehicle into reverse gear, and observe whether the exterior rearview mirrors tilt down automatically.

[0012] According to some embodiments of the present invention, the test method further includes: If the enabling function test is passed, the external rearview mirror will undergo voice control test, heating test and adaptive adjustment test. The voice control test includes testing the folding and unfolding of the exterior rearview mirrors via voice control; The heating test includes testing the function of turning the exterior rearview mirror heating on or off via the central control screen; The adaptive adjustment test includes testing the exterior rearview mirror to calculate the adaptive position of the exterior rearview mirror based on the driver's posture and automatically drive it to the adaptive position.

[0013] According to a second aspect of the present invention, a vehicle includes a memory and a processor. The memory stores a computer program, and the processor executes the computer program to implement the above-described method for testing exterior rearview mirrors.

[0015] According to some embodiments of the present invention, the vehicle further includes a voice acquisition module and a driver posture acquisition module. The voice acquisition module is used to collect voice control commands to control the folding and unfolding of the exterior rearview mirrors according to the voice control commands.

[0022] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of the present invention, not all embodiments.

[0023] Exterior rearview mirrors are fundamental components of a vehicle, and functional testing of exterior rearview mirrors is an indispensable part of overall vehicle functional testing. Exterior rearview mirror functions include position adjustment, position memory and retrieval, and automatic tilting down when reversing. The main components of the exterior rearview mirror system include the left and right exterior rearview mirrors, the virtual control buttons on the central control screen, and the mechanical buttons for adjusting the exterior rearview mirror position in the steering wheel combination switch. Simultaneously, the exterior rearview mirror system interacts with the vehicle's gear shift system, voice control system, and keyless entry system.

[0024] The numerous functions, complex components, and extensive interactions of exterior rearview mirror systems make testing a challenging and wide-ranging task. This critical task requires testers to conduct systematic, hierarchical testing. However, currently available technical solutions divide the testing of exterior rearview mirror motor performance, position feedback performance, and other functional aspects into separate modules for analysis and testing. This requires troubleshooting the entire system chain when locating problems. This fragmented testing approach struggles to address the challenges posed by the numerous functions, complex components, and extensive interactions of exterior rearview mirror systems. Consequently, the testing lacks systematicity and hierarchy, severely impacting efficiency and making the process cumbersome. Therefore, there is an urgent need to propose a systematic exterior rearview mirror testing method aimed at improving testing efficiency.

[0025] To address the aforementioned problems, this invention proposes a testing method and vehicle for exterior rearview mirrors, which effectively solves the problems of low efficiency and cumbersome operation steps in the existing technology for testing exterior rearview mirror functions.

[0026] refer to Figures 1 to 4 The following are embodiments of a testing method for an exterior rearview mirror according to the present invention: Reference Figure 1 The testing method for an exterior rearview mirror according to an embodiment of the present invention specifically includes the following steps: Step S100: Perform basic function tests on the exterior rearview mirrors, including testing the exterior rearview mirror position adjustment function and electric folding function; Step S200: If the basic function test passes, perform an enable switch test on the exterior rearview mirror. The enable switch test includes testing whether the enable switches involved in the exterior rearview mirror enable function can be turned on and off normally. Step S300: If the enable switch test passes, perform an enable function test on the exterior rearview mirror. The enable function test includes verifying the execution of the corresponding enable function when the enable switch is turned on and the triggering conditions are met. The enable functions include the automatic tilt function when reversing and the automatic folding function when locking the car. Step S500: If the enable function test passes, then the test of the exterior rearview mirror is verified to have passed.

[0027] In step S100, a basic function test is performed on the exterior rearview mirrors. The basic function test includes testing the position adjustment function and the electric folding function of the exterior rearview mirrors. The position adjustment function includes the adjustment operation of the left exterior rearview mirror moving up, down, left, and right, and the right exterior rearview mirror moving up, down, left, and right. The electric folding function includes the folding and unfolding operation of the exterior rearview mirrors. The basic functions specifically include ten operations.

[0028] Reference Figure 3 Both the left and right exterior rearview mirrors are equipped with adjustment motors and folding motors. The adjustment motors drive the left and right exterior rearview mirrors to adjust their positions to adapt to different usage scenarios and provide different rearward views. The folding motors drive the left and right exterior rearview mirrors to adjust their angles, thereby enabling the left and right exterior rearview mirrors to fold or unfold. This adjusts the rearward view and the space occupied by the exterior rearview mirrors, thus preventing scratches.

[0029] Reference Figure 3 and Figure 4 Specifically, the signal link for the position adjustment function originates from the virtual position adjustment button on the central control screen. The virtual button's command is linked to the mechanical adjustment button integrated into the steering wheel. When testing the position adjustment function of the exterior rearview mirror, the control command is initiated by operating the virtual button. Subsequently, the mechanical adjustment button of the corresponding exterior rearview mirror feeds back the driver's manual operation as an adjustment signal and transmits it to the drive motor of the corresponding exterior rearview mirror. The adjustment motor completes the position adjustment control based on the adjustment signal.

[0030] In the electric folding / unfolding function, the exterior rearview mirror motor directly receives the status signal from the virtual folding / unfolding button on the central control screen, and drives the folding / unfolding motor in the corresponding direction after determining the folding and unfolding status.

[0031] In this embodiment of the invention, the basic functions are taken as the starting point of the overall functional test and have the highest test priority. The test covers a wide range of hardware structure tests and software signal link tests of the exterior rearview mirror. If the test fails, the test ends and motor drive-related problems are investigated. This avoids wasting work by continuing to perform subsequent tests when the basic functions fail and avoids increasing the amount of testing.

[0032] Furthermore, in step S100, the basic function test of the exterior rearview mirror specifically includes: Step S110: Test whether the regulating motor and the folding motor respond to the control command in a timely manner; Step S120: Test whether the driving of the adjustment motor and the folding motor is continuous; Step S130: Test whether the adjustment motor and the folding motor can provide real-time feedback on the current position; Step S140: Test whether the regulating motor and the folding motor can accurately detect stall.

[0033] In step S110, in the position adjustment function, after operating the position adjustment virtual button on the central control screen, the response delay of the adjustment mechanical button turning the manual operation feedback into an adjustment signal and transmitting it to the corresponding motor is monitored; in the electric folding and unfolding function, after operating the folding and unfolding virtual button on the central control screen, the response delay of the folding and unfolding motor directly receiving the status signal is monitored.

[0034] By setting a reasonable response time threshold, it is possible to determine whether the motor can start in time after the control command is issued, so as to avoid the decline in driver operation experience or safety judgment errors due to slow response. This test ensures that the transmission efficiency of the signal link meets the real-time requirements and lays the foundation for subsequent drive continuity testing.

[0035] In step S120, the continuity of the adjustment motor and the folding motor drive is tested. After the adjustment motor and the folding motor start in response to the control command, the operation status of the adjustment motor in the four directions (up, down, left, and right) and the operation status of the folding motor during the folding and unfolding process are continuously monitored to verify whether the motor maintains a smooth and continuous drive output throughout the entire movement process, without any stuttering, interruption, or abnormal shaking. By tracking the change trend of the motor drive waveform or position feedback signal throughout the process, potential problems such as unstable power supply, abnormal mechanical resistance, or loss of control signals during the motor drive process are identified to ensure the smoothness and reliability of the exterior rearview mirror position adjustment and electric folding functions, thereby improving the user experience.

[0036] In step S130, the system tests whether the adjustment motor and the folding motor can provide real-time feedback on the current position. During the movement of the exterior rearview mirror driven by the motors, it monitors whether the position sensor or encoder built into the motors reports the current position information to the exterior rearview mirror controller at the expected cycle, verifying whether the update frequency and accuracy of the position feedback signal meet the real-time control requirements. By comparing the consistency between the position feedback received by the controller and the actual mechanical position, the integrity and accuracy of the position feedback link are determined. This test ensures that the system can accurately grasp the real-time attitude of the mirror during position adjustment and folding, providing reliable data support for functions such as position memory, position retrieval, and stall detection.

[0037] In step S140, the test motor and the folding motor are checked to ensure they can accurately detect stall. When the motor drives the exterior rearview mirror to its mechanical limit position or encounters abnormal resistance, the monitoring motor controller is checked to ensure it can promptly identify the stall state based on characteristics such as abnormal current increase, position feedback stagnation, or excessive drive time, and execute preset protection strategies such as stop drive or reverse protection. This prevents the motor from burning out due to prolonged overcurrent operation under stall conditions, protects the exterior rearview mirror's mechanical structure from damage, extends component lifespan, and reduces the risk of vehicle malfunction.

[0038] In step S200, if the basic function test passes, the enable switch test is performed on the exterior rearview mirror. The enable switch test includes testing whether the enable switches involved in the enable function of the exterior rearview mirror can be opened and closed normally. The enable functions specifically include automatic tilting down when reversing and automatic folding when locking the car.

[0039] Step S200 includes: testing whether the automatic reversing tilt enable switch can be turned on and off, including observing whether the enable signal controlling the automatic reversing tilt in the exterior rearview mirror software can perform the setting and resetting actions as the switch is turned on and off, and without any rebound; testing whether the automatic locking folding enable switch can be turned on and off, that is, observing whether the enable signal controlling the automatic locking folding in the exterior rearview mirror software can perform the setting and resetting actions as the switch is turned on and off, and without any rebound.

[0040] The enable switch, as a prerequisite for controlling the proper functioning of subsequent enabling functions, is tested after the basic function tests and before the enabling function tests, forming a logical progression. If this part of the test fails, the test ends and the enable switch-related issues are investigated. This prevents misjudgments in subsequent enabling function tests due to enable switch malfunctions, ensuring the scientific nature and accuracy of the testing process. By using a hierarchical testing approach, unnecessary tests are reduced, thereby improving testing efficiency.

[0041] In step S300, if the enable switch test passes, the enable function test is performed on the exterior rearview mirror. The enable function test includes verifying the execution of the corresponding enable function when the enable switch is turned on and the triggering conditions are met. The enable functions include the automatic tilt function when reversing and the automatic folding function when locking the car.

[0042] Specifically, during the automatic reversing tilt function test, turn on the automatic reversing tilt enable switch, put the vehicle in reverse gear, and observe the movement of the exterior rearview mirrors. After the test conditions are met, the right exterior rearview mirror should automatically tilt down to an angle that facilitates reversing. During the automatic locking folding function test, turn on the automatic locking folding enable switch. After the tester locks the car, the exterior rearview mirrors should automatically fold to the limit position and be driven to the center position in the vertical direction.

[0043] Enable function testing verifies whether the correspondence between the enable switch and the enable function is properly established, and verifies the completeness and accuracy of function execution through actual triggering conditions. If the enable function test fails, the test ends and the problem involving the enable switch is investigated. Utilizing the cross-validation characteristics of systematic testing, relevant basic function test items can be added to help locate the fault and improve the efficiency of problem investigation.

[0044] Reference Figure 2 Furthermore, in this embodiment of the invention, between step S300 and step S500, the following step is also included: Step S400: If the enabling function test passes, perform voice control test, heating test, and adaptive adjustment test on the exterior rearview mirror.

[0045] Step S400 is arranged after the basic functions, enable switch and enable function have been verified to pass. It reflects the test logic of progressively advancing from core functions to extended functions. Functions such as voice control, heating and adaptive adjustment are all based on the premise that the aforementioned basic functions are working properly. If the previous test fails, there is no need to enter this step, thereby avoiding the execution of meaningless extended function tests when the basic conditions are not met, effectively reducing the waste of test resources and improving the overall test efficiency.

[0046] Specifically, in step S400, the voice control test includes testing the folding and unfolding of the exterior rearview mirrors via voice control. The test involves issuing voice commands to fold or unfold the exterior rearview mirrors through the vehicle's voice control system, monitoring whether the exterior rearview mirror controller can correctly recognize the voice signal and interpret the control intent, thereby driving the folding and unfolding motor to execute the corresponding action. This test verifies whether the signal interaction between the voice control system and the exterior rearview mirror actuator is normal, ensuring that the driver can conveniently control the status of the exterior rearview mirrors via voice during driving, meeting the needs of intelligent human-machine interaction, and improving driving convenience and safety.

[0047] The heating test includes testing the ability to turn the exterior rearview mirror heating function on and off via the central control screen. Test personnel operate the heating function switch on the central control screen, monitoring whether the heating enable signal in the exterior rearview mirror software is correctly set and reset upon switch operation. Simultaneously, they observe whether the exterior rearview mirror surface temperature rises to the effective defrosting range within a specified time. This test verifies the integrity of the heating control chain and the working efficiency of the heating elements, ensuring that the exterior rearview mirror can promptly clear frost and fog from the mirror surface in low-temperature or rainy / snowy weather conditions, maintaining good rear visibility and ensuring driving safety.

[0048] The adaptive adjustment test involves calculating the appropriate position of the exterior rearview mirror based on the driver's posture and automatically driving it to that position. During the test, a camera captures the driver's posture information and transmits it to the exterior rearview mirror controller. The controller uses a built-in algorithm to calculate the mirror angle suitable for the driver's current body shape and posture, and then drives the adjustment motor to automatically adjust the exterior rearview mirror to the calculated appropriate position. This test verifies the collaborative working ability of the three key components: posture acquisition, algorithm calculation, and motor drive. This ensures that the exterior rearview mirror can provide personalized vision configurations for different drivers, reduce the burden of manual adjustment, and improve the vehicle's intelligence level and user experience.

[0049] In step S400, if the enable function test passes, the exterior rearview mirror test is verified as successful. This indicates that the basic functions, enable switch, and enable function of the exterior rearview mirror are all working normally, and the core function test has been completed. This verification step serves as the endpoint of the test process, confirming that the test results of the aforementioned three parts meet expectations, marking the successful completion of the main stages of the exterior rearview mirror system test. By strictly following the test sequence and determining the test process progress based on the test results of each test item, the test costs are effectively prevented from increasing due to meaningless test items, achieving a hierarchical and efficient testing process.

[0050] This invention reduces the number of unnecessary test items by arranging a logical and sequential systematic and comprehensive test order. Basic function test, enable switch test, and enable function test are performed in sequence. If any one of the basic function test, enable switch test, or enable function test fails, the technical test is terminated, and troubleshooting is performed based on the function corresponding to the failed test.
