Description

Technical Field

[0001] The present invention relates to the technical field of automobile testing, and in particular to a testing method and device for a vehicle body electronic stability control system. Background Art

[0002] Electronic Stability Control (ESC) is an active safety system that assists the driver in controlling the vehicle. Relying on sensors to monitor the vehicle's driving state in real time, it automatically corrects vehicle instability, maintaining lateral stability in common situations such as cornering, overtaking, and obstacle avoidance, where lateral interference could easily cause the vehicle to lose control. Under certain operating conditions or after prolonged use, some vehicles equipped with ESC may experience issues such as a persistent malfunction light, system-related malfunctions, and unusual noises. In these cases, the vehicle requires repair.

[0003] Currently, there is relatively little attention paid to the verification of the ESC system on the whole vehicle. A mature verification method has not been formed, and there are certain deficiencies in the judgment of test results. Summary of the Invention

[0048] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily appreciate the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the various details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0049] In the embodiment of the present invention, a vehicle electronic stability control system test method can be executed by a vehicle processor or a vehicle server. The following will be combined with a specific embodiment, taking the server as the execution subject as an example, to describe in detail a vehicle electronic stability control system test method provided by the present invention. Figure 1 The specific steps are as follows:

[0050] Step 101: Perform a function check on the electronic stability control system of the target vehicle to be tested.

[0051] In the embodiments of the present invention, the ESC system is mostly in a system-integrated state, integrating many systems including TCS (Traction Control System), HHC (Hill-start Assist Control), EPB (Electrical Park Brake), ABS (Anti-lock Braking System), etc.

[0052] The server performs a functional check on the ESC system of the target vehicle to determine whether the relevant functions of the ESC system are normal. During the functional check, the HHC system fault light, ABS system fault light, ESC system fault light, and EPB system fault light of the target vehicle are monitored in real time through a camera device, and the captured information is sent to the server.

[0053] If the server determines that any fault light is on, it determines that the relevant function check is abnormal, and an alarm is issued, prompting the ESC system to be reported for repair; if the server determines that all fault lights are not on, it determines that the relevant functions of the ESC system are normal, and the road test of the ESC system will continue.

[0054] Step 102 : If it is determined that the relevant functions of the vehicle electronic stability control system are normal, a road test related to the vehicle electronic stability control system is performed on the target vehicle.

[0055] In this embodiment of the present invention, if the server determines that the relevant functions of the ESC system are normal, it then performs a road test on the target vehicle related to the ESC system. During the road test, the target vehicle's HHC system fault light, ABS system fault light, ESC system fault light, and EPB system fault light are monitored in real time using a camera, and the captured information is sent to the server.

[0056] If the server determines that any fault light is on, it will determine that the road test is abnormal and issue an alarm, prompting the ESC system to be reported for repair.

[0057] Step 103: If the road test is normal, it is determined that the electronic stability control system of the target vehicle is normal.

[0058] In the embodiment of the present invention, if the server determines that all fault lights are off, it is determined that the road test of the ESC system is normal.

[0059] In the present invention, the server first performs a functional check on the ESC system. If no abnormalities are detected, a road test of the ESC system is performed. If both the functional check and the road test are normal, the ESC system of the target vehicle is determined to be normal. The present invention conducts a test that combines both functional checks and road tests, which can improve the accuracy of test results.

[0060] In addition, the present invention can quickly verify the functional stability of a vehicle equipped with the ESC system and the durability and reliability of the system hardware during actual use, thereby reducing the risk of quality problems after the vehicle is put on the market, improving product competitiveness, and saving after-sales costs caused by ESC system-related problems.

[0061] As an optional implementation, the relevant functional inspections of the electronic stability control system of the target vehicle to be tested include: functional inspections of the traction control system, the hill assist system, the electronic parking brake system, the anti-lock braking system, a limit steering driving inspection, a first speed driving inspection, a vibrating road driving inspection, a serpentine driving inspection, and a wading condition inspection, wherein the first speed is applicable to highways, the limit steering driving is to drive in a figure 8 at the second speed, and the second speed is applicable to congested roads.

[0062] The electronic stability control system includes traction control system, hill assist system, electronic parking brake system and anti-lock braking system; the electronic stability control system is used in the target vehicle's extreme steering driving, first speed driving, vibrating road driving, serpentine driving and wading.

[0063] Among them, the above nine functional checks must be carried out, but the order of the checks is not limited.

[0064] Figure 2 The following is a flowchart of the relevant function checks of the ESC system. The following is a detailed description of each function check.

[0065] 1. Traction control system function check: Perform traction tests on the left wheel, right wheel, and all four wheels respectively, and observe whether the ESC indicator light on the instrument panel flashes normally. If it flashes normally, it indicates that the TCS system is working normally; if it flashes abnormally, it indicates that the TCS system is working abnormally.

[0066] TCS is an active vehicle safety system. When a vehicle encounters unusual road conditions, the vehicle's computer monitors the differential speeds of the tires and determines the appropriate traction to maintain maximum vehicle stability and ensure driving safety. If the wheels slip or drift, the computer immediately determines whether the vehicle's driving force is excessive. If so, the computer reduces engine power. While TCS is active, the vehicle is typically kept in a higher gear. The computer detects wheel speeds to determine if they exceed computer-set limits. If so, the computer signals the driver to release the accelerator or apply the brakes, allowing the drive wheels to pull the vehicle back into normal travel. Besides slipping and drifting, TCS effectively controls vehicle roll when ascending or descending hills, providing enhanced safety for vehicles equipped with TCS.

[0067] 2. Hill Start Assist System Function Check: This is performed on slopes of varying gradients (e.g., 10%, 20%, and 30%). Stop the target vehicle in the middle of the slope (ensure the vehicle is completely stopped and the speed is zero). With the vehicle in D gear, release the brake pedal and determine whether the instrument panel's Hill Start Assist System fault light is functioning properly. If so, the HHC function is functioning properly. If not, the HHC function is functioning abnormally.

[0068] When starting a vehicle on a steep or slippery slope, if the driver switches from the brake pedal to the accelerator, the vehicle could roll backward, making it difficult to start. To prevent this, Hill Start Assist Control temporarily (up to approximately 2 seconds) applies the brakes to all four wheels to prevent the vehicle from rolling backward. When equipped with Hill Start Assist, Hill Start Assist Control prevents the vehicle from rolling backward, allowing you to start the vehicle and operate the pedals with ease. When you release the brake pedal, the Hill Start Assist indicator flashes, indicating that Hill Start Assist is active.

[0069] 3. Electronic parking brake system function check: Perform this check on slopes of different gradients (e.g. 10%, 20%, 30%), stop the target vehicle in the middle of the slope (make sure the vehicle is completely stopped and the speed is zero), shift the gear into neutral, press the parking switch, and determine whether the parking system indicator light on the instrument is normally lit. If it is normally lit, it confirms that the EPB system is working normally; if it is abnormally lit, it confirms that the EPB system is working abnormally.

[0070] The EPB system integrates temporary braking during driving and long-term braking after stopping, using electronic control to achieve parking. The EPB system automatically applies the parking brake after the engine is turned off, providing convenient and reliable parking, preventing accidental release, and acting as a service brake in an emergency. Pressing the electronic parking brake while driving at high speed will force the vehicle to the brakes until it stabilizes, with a braking force of approximately 80% of full braking.

[0071] 4. Anti-lock Braking System Function Check: Brake at three different speeds: low (second speed), medium (third speed), and high (first speed). Observe the instrument panel to see if any fault lights illuminate. If any light illuminates, the ABS function is abnormally triggered. If no light illuminates, the ABS function is normal. Malfunction lights include the ABS, ESC, and EPB fault lights.

[0072] The ABS system is mainly used to prevent rollover caused by wheel slippage, while shortening the braking distance, reducing braking consumption, and extending the service life of brake discs and tires. The anti-lock braking system can improve the safety factor of driving and vehicle emergency braking.

[0073] 5. Extreme Steering Driving Check: Perform a figure-eight driving motion at a low speed (second speed) and determine if any instrument panel lights illuminate. If so, the extreme steering function has been abnormally activated. If not, the extreme steering function has been properly activated. Malfunction lights include the ABS, ESC, and EPB indicators. For example, the second speed is 20 km / h.

[0074] 6. First Speed ​​Check: Drive at high speed (first speed) (recommended no more than 100 km / h) and determine if any instrument panel lights are illuminated. If any lights are illuminated, the high-speed function is abnormally triggered. If no lights are illuminated, the high-speed function is properly triggered. Malfunction lights include the ABS, ESC, and EPB lights. For example, the first speed is 120 km / h.

[0075] 7. Vibrating Road Driving Check: Drive the vehicle on a vibrating road at a medium speed (the third vehicle speed) to check for abnormal ESC actuator noise and determine if the fault light illuminates during driving. If the fault light illuminates, the vibrating road driving function has been abnormally triggered. If the fault light does not illuminate, the vibrating road driving function has been properly triggered. Fault lights include the ABS, ESC, and EPB fault lights. For example, the third vehicle speed is 40 km / h.

[0076] 8. Snake Driving Check: Perform a serpentine driving test at a medium speed (the third vehicle speed) to check if any instrument panel lights illuminate during driving. If any lights illuminate, the serpentine driving function has been abnormally activated. If no lights illuminate, the serpentine driving function has been properly activated. Malfunction lights include the ABS, ESC, and EPB lights. For example, the third vehicle speed is 40 km / h.

[0077] 9. Wading Check: Drive the vehicle in a serpentine pattern at a medium speed (the third speed) to check if any instrument panel lights illuminate. If so, the wading function has been activated abnormally. If not, the wading function has been activated normally. Malfunction lights include the ABS, ESC, and EPB. For example, the third speed is 40 km / h.

[0078] As an optional implementation, road testing of the target vehicle related to the electronic stability control system includes: serpentine driving and vibration road driving tests on the target vehicle, second speed anti-lock braking test, second speed extreme steering driving test, third speed anti-lock braking and wading condition test, first speed loop driving and first speed anti-lock braking test, traction control system test, hill assist system and electronic parking brake system functional test, wherein the third speed is between the first speed and the second speed.

[0079] Figure 3 This is a flowchart for the road test of the ESC system. The order of the road test is not limited.

[0080] The road test includes one or more functions from the functional inspection. For example, the serpentine driving and vibrating road driving tests involve serpentine driving on a vibrating road surface to determine whether the malfunction indicator light illuminates. Another example is the third-speed anti-lock braking and water-wading test, which involves braking at the third speed while driving through water to determine whether the malfunction indicator light illuminates.

[0081] The way to determine whether the road test is normal is the same as the way to determine the functional check, which is based on whether the fault light is normally lit and the information on the instrument panel is correct.

[0082] The number of road tests is determined based on the expected life of the ESC system and the number of target vehicles.

[0083] As an optional implementation, before conducting a road test on the target vehicle regarding the vehicle body electronic stability control system, the method also includes: obtaining the vehicle model of the target vehicle; determining the maximum vehicle load of the target vehicle based on a preset correspondence and the vehicle model; and controlling the robotic arm to load the target vehicle so that the target vehicle reaches the maximum vehicle load.

[0084] The server identifies the vehicle model of the target vehicle through a vehicle identification device. The server stores the correspondence between the vehicle model and the maximum vehicle load. The server determines the maximum vehicle load of the target vehicle through the correspondence and the vehicle model, and then controls the robotic arm to load the target vehicle so that the target vehicle reaches the maximum vehicle load.

[0085] The present invention adopts a fully loaded target vehicle for road testing, which takes into account the road driving of a fully loaded vehicle in actual scenarios. If the test is normal under the fully loaded scenario, it can ensure that the ESC system is also normal when the degree of damage is bad, and the vehicle stability can be improved.

[0086] As an optional implementation, the normality of the road test is determined in the same manner as the normality of the relevant functional checks: the illumination of the malfunction lights and the correctness of the information displayed on the instrument panel. Specifically, the camera monitors the target vehicle's hill start assist system malfunction lights, anti-lock brake system malfunction lights, electronic stability control system malfunction lights, electronic parking brake system malfunction lights, and the information displayed on the instrument panel. The monitored information is then transmitted to a server, which determines that all malfunction lights are off and the information displayed on the instrument panel is correct.

[0087] As an optional implementation, after determining that the road test is normal, the method also includes: performing a relevant function check of the body electronic stability control system of the target vehicle to be tested; if it is determined that the relevant functions of the body electronic stability control system are normal, then determining that the body electronic stability control system of the target vehicle is normal.

[0088] After the target vehicle is subjected to a relevant function inspection and road test, if it is determined that the ESC system is normal, it is necessary to continue to perform a relevant function inspection of the ESC system on the target vehicle to determine whether the relevant function of the ESC system is abnormal after the road test. If the relevant functions of the ESC system are also normal at this time, it indicates that no abnormal situation occurred during the road test. At this time, the test of the ESC system is completed and the test result is qualified. The present invention finally performs a functional test of the ESC system on the vehicle again, which can form a test closed loop (relevant function inspection-road test-relevant function inspection), improve the integrity of the test, and improve the test accuracy.

[0089] As an optional implementation, before performing the first relevant functional inspection of the electronic stability control system of the target vehicle to be tested, the method also includes: starting the prototype vehicle, wherein the mileage of the prototype vehicle after leaving the factory does not exceed a preset distance, and the time from the time of leaving the factory to the time of testing does not exceed a preset length; if it is determined through a photographing device that there is no fault indicator light on the prototype vehicle, then triggering various functions of the electronic stability control system of the prototype vehicle through a robotic arm; if all functions of the electronic stability control system can be triggered, the prototype vehicle is determined to be the target vehicle.

[0090] The number of prototype vehicles is limited to 2-4, all in good condition. Their factory mileage does not exceed a preset distance, such as 1000 km, and the time between factory departure and test time does not exceed a preset period, such as one year. Using these prototype vehicles can avoid inaccurate testing due to wear and tear. The server controls the startup of the prototype vehicle. After startup, a camera captures the status of the malfunction indicator light and sends this information to the server. If the server determines that the malfunction indicator light is not on, it controls the robotic arm to sequentially trigger various functions of the prototype vehicle's ESC system. If the triggering results are normal, the prototype vehicle is identified as the target vehicle.

[0091] Figure 4 This is the overall test flow chart. It can be seen that the test process is: sample vehicle access; relevant function inspection of the ESC system; road test related to the ESC system; relevant function inspection of the ESC system.
