In the following, in conjunction with specific implementation methods, taking the server as the execution subject as an example, a test method of a vehicle body electronic stability control system provided by the present invention will be described in detail, as shown in Figure 1, and the specific steps are as follows:

Step 101: Perform a functional check of the vehicle body electronic stability control system for the target vehicle to be tested.

In the embodiment of the present invention, the ESC system is mostly in the system integration state, integrating TCS (Traction Control System, traction control system), HHC (Hill-start Assist Control, hill assist system), EPB (Electrical Park Brake, electronic parking braking system), ABS (Anti-lock Braking System, anti-lock braking system) and many other systems.

The server checks the function of the ESC system of the target vehicle to be tested, so as to determine whether the relevant functions of the ESC system are normal. During the function inspection process, 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 the shooting device, and the shooting information is sent to the server.

If the server determines that any fault light is on, it determines that the relevant function check is abnormal, and then sends an alarm to prompt the ESC system to report 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 then continue Carry out a road test on the ESC system.

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

In the embodiment of the present invention, if the server determines that the relevant functions of the ESC system are normal, it will conduct a road test related to the ESC system on the target vehicle. During the road test, 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 the shooting device, and the shooting information is sent to the server.

If the server determines that any fault light is on, it determines that the road test is abnormal, and then sends an alarm to prompt the ESC system to be repaired.

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

In the embodiment of the present invention, if the server determines that all fault lights are not lit, it determines that the road test of the ESC system is normal.

In the present invention, the server first checks the relevant functions of the ESC system, and if it is determined that there is no abnormality, then conducts a road test related to the ESC system, and if the relevant function checks and road tests are normal, then it is determined that the ESC system of the target vehicle is normal. The test of the present invention is carried out from two aspects of function inspection and road test, which can improve the accuracy of test results.

In addition, the present invention can quickly verify the stability of the function of the vehicle equipped with the ESC system and the durability and reliability of the system hardware during actual use, reduce the risk of quality problems after the vehicle is launched, improve product competitiveness, and save costs related to the ESC system. After-sales costs caused by problems.

As an optional implementation, the relevant functional inspection of the electronic stability control system of the vehicle body on the target vehicle to be tested includes: a functional inspection of the traction control system, a functional inspection of the hill assist system, and an electronic parking brake on the target vehicle. System function inspection, function inspection of anti-lock braking system, limit steering driving inspection, first speed driving inspection, vibrating road surface driving inspection, serpentine driving inspection and wading condition inspection, among them, the first speed is applicable to high-speed On highways, extreme steering is to use the second speed to drive in a figure-of-eight shape, and the second speed is suitable for congested roads.

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

Figure 2 is a flow chart of the relevant functional inspection of the ESC system, and each functional inspection will be described in detail below.

1. Functional inspection of the traction control system: test the traction force of the left wheel, right wheel and four wheels respectively, and observe whether the ESC indicator light on the instrument flashes normally. If it flashes normally, it means that the TCS system is working normally; if it flashes abnormally, Then it is determined that the TCS system is working abnormally.

TCS belongs to the active safety system of the car. TCS traction control system means that when the car encounters special road conditions during driving, the car's calculator computer detects the different differential speeds of the tires, and judges that different traction forces are used to maintain the maximum stability of the vehicle and ensure driving safety. When the wheels spin or flick, the calculator will immediately judge whether the driving force of the vehicle is too high. When the driving force is too large, the computer sends instructions to reduce the output of the engine energy. When TCS is working, the gear of the vehicle will usually be maintained at a higher gear, and it will judge whether it exceeds the limit value set by the computer by sensing the wheel speed. Once it exceeds the computer, it will send a signal to release the accelerator or step on the brake, so that the driving wheels of the vehicle will pull the vehicle back to the normal driving direction under the action of traction. In addition to slipping or tail flicking, TCS can effectively control the vehicle's roll when going uphill or downhill, so the safety of vehicles equipped with TCS will be better.

2. Slope assist system function check: Carry out on slopes with different slopes (such as 10%, 20%, 30%), stop the target vehicle in the middle of the slope (make sure the vehicle stops completely and the speed is zero) , In the D gear state, release the brake pedal, and judge whether the instrument hill assist system fault light is normal. If it is normal, it is determined that the HHC function is triggered normally; if it is abnormal, it is determined that the HHC function is triggered abnormally.

When the vehicle starts on a steep or slippery slope, the driver switches from the brake pedal to the accelerator pedal, and the vehicle will slide backwards, resulting in difficulty in starting; to prevent this from happening, the hill assist system temporarily controls the ) apply the brakes to all four wheels to prevent the vehicle from sliding. When equipped with hill assist, it is easy to drive off and operate the pedals because the hill start assist control prevents the vehicle from rolling backwards. When the brake pedal is released, the hill start assist indicator light flashes to indicate that hill start assist is activated.

3. Electronic parking brake system function check: Carry out on slopes with different slopes (such as 10%, 20%, 30%), and stop the target vehicle in the middle of the slope (make sure the vehicle stops completely and the speed is zero), put into neutral, press the parking switch, and judge whether the parking system indicator light on the instrument is normally on. If it is normally on, it confirms that the EPB system is working normally; if it is abnormally on, it is confirmed that the EPB system is working abnormally.

The EPB system refers to the integration of temporary braking during driving and long-term braking after parking, and realizes parking braking by electronic control. The EPB system can automatically apply the parking brake after the engine is turned off. It is convenient and reliable to park, and can prevent accidental release. It can be used as a service brake in an emergency. Press the electronic handbrake while driving at high speed, the vehicle will perform forced braking until the vehicle is stable, and the braking force is about 80% of the full braking force.

4. Anti-lock braking system function check: brake at three different speeds: low speed (second speed), medium speed (third speed) and high speed (first speed), and observe whether there is a fault light on the instrument; If there is a fault light on, it is confirmed that the ABS function is triggered abnormally; if no fault light is on, it is confirmed that the ABS function is triggered normally. Among them, the fault lights include ABS fault lights, ESC fault lights and EPB fault lights.

The ABS system is mainly used to prevent rollover caused by wheel slippage, shorten the braking distance, reduce braking consumption, and prolong the service life of the brake disc and tire. The anti-lock braking system can improve the safety of driving and emergency braking of the vehicle. Safety factor.

5. Limit steering driving inspection: Carry out figure 8 driving at a low speed (the second vehicle speed), and judge whether there is a fault light on the instrument during driving; if there is a fault light on, confirm that the limit steering function is triggered abnormally; if there is no fault light If it is on, it confirms that the limit steering function is triggered normally. Among them, the fault lights include ABS fault lights, ESC fault lights and EPB fault lights. Exemplarily, the second vehicle speed is 20km/h.

6. First speed driving inspection: drive at high speed (first speed) (recommended not to exceed 100km), and judge whether there is a fault light on the instrument during driving; if there is a fault light on, confirm that the high-speed driving function is abnormally triggered; If no fault light is on, then confirm that the high-speed driving function is triggered normally. Among them, the fault lights include ABS fault lights, ESC fault lights and EPB fault lights. Exemplarily, the first vehicle speed is 120km/h.

7. Vibrating road driving inspection: drive on the vibrating road at medium speed (the third speed), confirm whether the ESC actuator makes abnormal noise, and judge whether the fault light is on during driving; if any fault light is on, check the vibrating road The driving function is triggered abnormally; if no fault light is on, it is confirmed that the driving function on the vibrating road is triggered normally. Among them, the fault lights include ABS fault lights, ESC fault lights and EPB fault lights. Exemplarily, the third vehicle speed is 40km/h.

8. Serpentine driving inspection: Carry out serpentine driving at a medium speed (the third speed), and confirm whether there is a fault light on the instrument panel during driving; if any fault light is lit, confirm that the snake driving function is triggered abnormally; If no fault light is on, it is confirmed that the serpentine driving function is triggered normally. Among them, the fault lights include ABS fault lights, ESC fault lights and EPB fault lights. Exemplarily, the third vehicle speed is 40km/h.

9. Inspection of wading conditions: drive in a snake shape at a medium speed (the third speed), and confirm whether there is a fault light on the instrument panel during driving; if there is a fault light on, confirm that the wading function is triggered abnormally; If no fault light is on, then confirm that the wading function is triggered normally. Among them, the fault lights include ABS fault lights, ESC fault lights and EPB fault lights. Exemplarily, the third vehicle speed is 40km/h.

As an optional implementation, the road test on the target vehicle related to the electronic stability control system of the vehicle body includes: performing a serpentine driving and vibrating road surface driving test on the target vehicle, a second speed anti-lock braking test, and a second vehicle speed anti-lock braking test.

Fig. 3 is a flow chart of the road test related to the ESC system, and the order of the road test is not limited.

The content of the road test includes one or more functions in the functional inspection content, such as snake driving and vibration road driving test, which is to carry out snake driving on the vibration road, and then determine whether the fault light is on. Another example, the third speed anti-lock braking and wading condition test is to use the third speed to brake at the third speed during driving on the wading section to determine whether the fault light is on.

The way to determine whether the road test is normal is the same as the way to determine the functional inspection, both according to whether the fault light is on normally and the information on the instrument panel is correct.

Among them, the test frequency of the road test is determined according to the expected life of the ESC system and the number of target vehicles.

As an optional implementation, before conducting the road test on the vehicle body electronic stability control system on the target vehicle, the method further includes: acquiring the vehicle model of the target vehicle; Maximum loading capacity; control the mechanical arm to load the target vehicle so that the target vehicle can reach the maximum loading capacity.

The server identifies the vehicle model of the target vehicle through the vehicle identification device. The server stores the correspondence between the vehicle model and the maximum vehicle capacity, and through the corresponding relationship and the vehicle model, determines the maximum vehicle capacity of the target vehicle, and then controls the mechanical arm to The target vehicle is loaded so that the target vehicle reaches the maximum loading capacity.

The present invention uses a fully loaded target vehicle for road testing, considering that the road driving of the fully loaded vehicle in the actual scene is normal, and the test is normal in the full load scene, which can ensure that the ESC system is also normal when it is bad, and can improve the stability of the vehicle.

As an optional implementation, the way to determine whether the road test is normal is the same as the way to determine whether the relevant function inspection is normal, and both are determined according to whether the fault light is on and whether the information on the instrument panel is correct. Specifically, the shooting device monitors the target vehicle's hill assist system fault light, anti-lock braking system fault light, body electronic stability control system fault light, electronic parking brake system fault light, and information on the instrument panel. , and then send the monitoring information to the server, and the server confirms that all fault lights are off and the information on the dashboard is normal.

As an optional implementation, after it is determined that the road test is normal, the method further includes: checking the relevant functions of the vehicle body electronic stability control system for the target vehicle to be tested; if it is determined that the relevant functions of the vehicle body electronic stability control system are normal, then determine the target The vehicle's electronic stability control system is normal.

After the relevant function inspection and road test of the target vehicle, if it is determined that the ESC system is normal, it is necessary to continue to carry out the relevant function inspection of the ESC system on the target vehicle, so as to determine whether there is any abnormal function of the ESC system after the road test. If the relevant functions of the ESC system are also normal at this time, it means that there is no abnormality during the road test, and the test of the ESC system is completed and the test result is qualified. Finally, the present invention carries out the function detection of the ESC system again on the vehicle, which can form a test closed loop (related function inspection-road test-related function inspection), improve the integrity of the test, and improve the accuracy of the test.

As an optional implementation, before the target vehicle to be tested is checked for the relevant functions of the electronic stability control system of the vehicle body for the first time, the method further includes: starting the prototype vehicle, wherein the mileage of the prototype vehicle does not exceed a preset distance after leaving the factory.

The mileage after leaving the factory does not exceed the preset distance, such as 1000km, and the time between the time of leaving the factory and the time of testing does not exceed the preset time, such as 1 year. The problem of inaccurate testing caused by the wear and tear of the vehicle itself. The server controls the startup of the prototype car. After startup, the shooting device obtains the status of the fault indicator light and sends the status information to the server. If the server determines that the fault indicator light is not on, it controls the mechanical arm to trigger various functions of the ESC system of the prototype car in turn. If it is determined that the trigger result is normal, then the sample vehicle is determined to be the target vehicle.
