[0047] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0048] In a first aspect, an embodiment of the present invention provides a method for testing the functions of an advanced driver assistance system.

[0049] In one embodiment, referring to Figure 1 , Figure 1 is a schematic flowchart of an embodiment of the method for testing the functions of the advanced driver assistance system of the present invention. As Figure 1 shown, the method for testing the functions of the advanced driver assistance system includes:

[0050] Step S10, controlling the test vehicle to circulate on the road corresponding to the function to be tested;

[0051] In this embodiment, the vehicle is first preliminarily tested to detect whether the vehicle performance meets the relevant standards, and the vehicle with performance meeting the relevant standards is used as the test vehicle. Controlling the test vehicle to circulate on the road corresponding to the function to be tested, so as to conduct a durability test on each function of the advanced driver assistance system of the test vehicle.

[0052] Step S20, obtaining the test result of the function to be tested based on the running condition of the test vehicle during the circulating driving process.

[0053] In this embodiment, the running condition of the test vehicle during the circulating driving process is obtained. If the running condition of the test vehicle during the circulating driving process meets the corresponding conditions, the test result of the function to be tested is that the function to be tested is normal. If the running condition of the test vehicle during the circulating driving process does not meet the corresponding conditions, the test result of the function to be tested is that the function to be tested is abnormal.

[0054] In this embodiment, the test vehicle is controlled to circulate on the road corresponding to the function to be tested; the test result of the function to be tested is obtained based on the running condition of the test vehicle during the circulating driving process. Through this embodiment, first control the test vehicle to conduct a durability test on the road corresponding to the function to be tested, and then the test result of the function to be tested in the advanced driver assistance system can be obtained based on the running condition of the test vehicle during the durability test. There is no need to conduct tests on actual roads, and all functions to be tested in the normal state can be started, solving the problems of high cost, high test risk and low efficiency in the durability test of the functions of the current advanced driver assistance system.

[0055] Further, in one embodiment, when the function to be tested is the adaptive cruise control system function, step S10 includes:

[0056] Controlling the test vehicle to follow the target vehicle and drive on the second loop for a corresponding preset number of times.

[0057] In this embodiment, first detect whether the test vehicle is normal. Specifically, referring to Figure 2 , Figure 2 is a schematic diagram of the test scenario of the first embodiment of the method for testing the functions of the advanced driver assistance system of the present invention. As Figure 2As shown, the control test vehicle enters the second loop through the second loop entrance. When driving on the west straight section of the second loop and approaching the No. 4 braking road, the vehicle speed is reduced to 50 km / h. On the No. 4 braking road, it brakes to a stop at a deceleration of 4 m / s 2 When starting and accelerating and approaching the No. 1 braking road, the vehicle speed is reduced to 50 km / h. After entering the No. 1 braking road, it decelerates at a deceleration of 4 m / s 2 (without stopping). The maximum vehicle speed on the west straight section does not exceed 80 km / h. When accelerating and approaching the No. 2 braking road, the vehicle speed is reduced to 50 km / h. After entering the No. 2 braking road, it brakes to a stop at a deceleration of 4 m / s 2 The maximum driving speed on the north bend of the second loop shall not exceed 65 km / h. When starting and accelerating and approaching the No. 3 braking road, the vehicle speed is reduced to 50 km / h. After entering the No. 3 braking road, it brakes and decelerates at a deceleration of 4 m / s 2 (without stopping). After the test vehicle completes the above driving, confirm that the test vehicle is normal.

[0058] After confirming that the test vehicle is normal, when the function to be tested is the adaptive cruise control system function, control the test vehicle to follow the target vehicle on the second loop for the corresponding preset number of times. At this time, the preset number of times is once. Specifically, in one embodiment, control the test vehicle to continue driving along the second loop. After passing through the second loop entrance, turn on the adaptive cruise control (ACC) function, set the vehicle speed to 60 km / h, and drive stably at the set vehicle speed of 60 km / h along the inner lane of the second loop before reaching the No. 4 braking road. After the No. 4 braking road, there is a target vehicle for cooperation testing driving at 50 km / h along the inner lane of the second loop. After the test vehicle identifies the target vehicle and follows the target vehicle stably, the target vehicle gradually accelerates to 80 km / h and decelerates to 30 km / h before reaching the bend in front of the No. 1 braking road, passes through the continuous bend and passes through the No. 2 braking road.

[0059] In one embodiment, the test vehicle enters the second loop. After passing through the second loop entrance, turn on the vehicle's adaptive cruise control (ACC), set the vehicle speed to 60 km / h, and drive along the inner lane of the second loop. Reach the set vehicle speed and drive stably before reaching the No. 4 braking road. After the No. 4 braking road, there is a target vehicle for cooperation testing driving at 50 km / h along the inner lane of the second loop. After the test vehicle identifies the target vehicle and follows the target vehicle stably, the target vehicle decelerates to a stop in front of the second comprehensive intersection for about 3 s and then starts to continue driving. The test vehicle follows the target vehicle.

[0060] Further, in one embodiment, when the function to be tested is the blind spot monitoring system function, step S10 includes:

[0061] Control the test vehicle to drive at a constant speed on the second loop for the corresponding preset number of times until the target vehicle accelerating exceeds the test vehicle.

[0062] In this embodiment, continue to refer to Figure 2 , when the function to be tested is the blind spot monitoring system function, control the test vehicle to travel at a constant speed on the second loop for a corresponding preset number of times until the target vehicle accelerating exceeds the test vehicle. At this time, the preset number of times is once. Specifically, in one embodiment, the target vehicle travels at a constant speed of 30 km / h. After the test vehicle exits the north bend of the second loop, it changes to the outer lane of the second loop and travels at a constant speed of 50 km / h for 25 s. Then the target vehicle accelerates to 70 km / h until it exceeds the test vehicle.

[0063] In one embodiment, the test vehicle exits from the urban center loop exit and enters the second loop. The cooperating vehicle exits from the urban center loop exit. After the test vehicle exits the north bend of the second loop, it changes to the inner lane of the second loop and travels at a constant speed of 50 km / h for 25 s. Then the target vehicle accelerates to 70 km / h in the adjacent lane until it exceeds the test vehicle, and the test ends before the No. 2 braking road.

[0064] Further, in one embodiment, when the function to be tested is the rear warning and braking function, step S10 includes:

[0065] Control the test vehicle to drive into the standard ramp square via the standard ramp and enter the reverse mode to drive towards the static obstacle for a corresponding preset number of times.

[0066] In this embodiment, refer to Figure 3 , Figure 3 is a schematic diagram of the test scenario of the second embodiment of the test method for the advanced driver assistance system function of the present invention. As shown in Figure 2 and Figure 3 , when the function to be tested is the rear warning and braking function, the function of the vehicle braking system is first confirmed before the test vehicle is tested. Specifically, control the test vehicle to enter the standard ramp, drive out from the No. 3 braking road, drive along the second loop to turn left into the standard ramp test area, climb the 16.6% ramp to the central position and brake to stop, release the parking brake and release the service brake. After 2 seconds, the vehicle starts on the ramp and drives along the 16.6% ramp to the top of the standard ramp. Then drive down the 20% ramp in an appropriate gear and apply the parking brake once in the middle of the ramp. Make a U-turn and drive to the bottom of the 30% ramp to stop. The vehicle drives onto the 30% ramp at a speed of 10 km / h. When the vehicle is completely on the 30% ramp, accelerate uphill at full throttle, but the vehicle speed is not allowed to exceed 40 km / h. When reaching the top of the ramp, decelerate to 15 km / h. Drive down the 20% ramp in an appropriate gear.

[0067] After the above driving, if the vehicle braking system is working properly, conduct a durability test on the rear warning and braking functions of the vehicle's advanced driver assistance system. That is, control the test vehicle to drive into the standard ramp square via the standard ramp and enter the reverse mode to drive towards the static obstacle for a preset number of times. At this time, the preset number of times is 3 times. Specifically, the test vehicle drives into the standard ramp square via the standard ramp, enters the rear warning and emergency braking test area, the test vehicle enters the reverse mode, accelerates the vehicle to 10 km / h and drives towards the static obstacle, repeats 3 times, and turns left into the second loop after completion.

[0068] Further, in one embodiment, when the function to be tested is the emergency braking system function, step S10 includes:

[0069] Control the test vehicle to drive uniformly along the vertical path of the obstacle driving direction on the straight performance road for a corresponding preset number of times;

[0070] In this embodiment, refer to Figure 4 , Figure 4 which is the test scenario schematic diagram of the third embodiment of the test method for the advanced driver assistance system function of the present invention. As shown in Figure 4 and Figure 2 , when the function to be tested is the emergency braking system function, control the test vehicle to drive uniformly along the vertical path of the obstacle driving direction on the straight performance road for a corresponding preset number of times. At this time, the preset number of times is 3 times. Specifically, in one embodiment, after the test vehicle enters the straight performance road via the second loop and the roundabout, it maintains a uniform speed of 30 km / h, enters the pedestrian crossing test area, and after passing through the pedestrian movement trigger area, the pedestrian moves at a speed of 6.5 km / h in a direction perpendicular to the vehicle driving direction, and repeats the test 3 times.

[0071] In one embodiment, the test vehicle decelerates through the north bend of the performance road and drives along the outer road at a speed of 50 km / h, enters the pedestrian walking along the road test area. After the vehicle passes through the pedestrian movement trigger area, the pedestrian moves at a speed of 5 km / h in the same direction as the vehicle driving direction. After the vehicle actively brakes, the test vehicle changes lanes and continues to drive for 30 s, then decelerates to 40 km / h and stably drives for 5 s, and then enters the static target vehicle test area, and repeats the test 3 times.

[0072] Further, in one embodiment, when the function to be tested is the lane keeping assistance system function, step S10 includes:

[0073] Control the test vehicle to deviate from the lane at a preset deviation speed on the straight performance road for a corresponding preset number of times.

[0074] In this embodiment, continue to refer to Figure 2 and Figure 4When the function to be tested is the lane keeping assist system function, the test vehicle is controlled to deviate from the lane at a preset deviation speed on a straight performance road for a preset number of times. At this time, the preset number is 3 times. Specifically, after the test vehicle passes the pedestrian crossing test area, it quickly accelerates to 70±2km / h and drives steadily for 5s, and then enters the lane keeping assist system function (LKA) test area. On the straight performance road, the test vehicle deviates to the left or right at a deviation speed of (0.4±0.2)m / s, and repeats 3 times.

[0075] Furthermore, in one embodiment, when the function to be tested is a rear traffic passing system function, step S10 includes:

[0076] The test vehicle is controlled to enter the parking area of ​​the city center circular square through Belgium Road, enter the reverse mode and start braking.

[0077] In this embodiment, continue to refer to Figure 2 When the function to be tested is the rear traffic crossing reminder system function, before the durability test of the rear traffic crossing reminder system function, the user's urban use conditions are simulated first, that is, the test vehicle enters the No. 2 ring road through the roundabout, and enters the south entrance of Belgium Road through the south bend of the No. 2 ring road. First, it drives one circle on Belgium Road (stone road) in a clockwise direction. The speed of the section from the shallow pool on the east side of Belgium Road to the south bend shall not exceed 15km / h, and the speed of other sections shall not exceed 25km / h. In the second circle, drive along the monitoring road on the northwest side of Belgium Road to the simulated urban working condition road, drive along the city center loop for 20 minutes, and after driving more than 6.5km, stop at the red light and go at the green light. Pass through the circular square at least 10 times (not continuously), exit from different exits each time, and enter the water area of ​​the city center circular square at least 10 times, and the single raining time is not less than 20s. After the simulation is completed, the rear traffic crossing reminder system function is carried out for durability test. Specifically, the test vehicle is controlled to enter the parking area of ​​the city center circular square, parked at a suitable position, with the front of the vehicle facing the outside of the square, and the test vehicle enters the reverse mode, and the brake is activated. Then the target vehicle in the test drives past the rear end of the vehicle at a constant speed of 20km / h on a path perpendicular to the test vehicle. The target vehicle repeats driving in both directions for 3 times, the test ends, and the test is repeated 4 times.

[0078] Further, in one embodiment, when the function to be tested is a highway auxiliary system function, step S10 includes:

[0079] The test vehicle is controlled to turn on the highway assistance system function, and travels a corresponding preset number of laps on the highway loop at a speed greater than a first preset vehicle speed.

[0080] In this embodiment, continue to refer to Figure 2, when the function to be tested is the highway assist system function, control the test vehicle to activate the highway assist system function and drive on the high-speed loop for a corresponding number of preset laps at a speed greater than the first preset speed. At this time, the preset number of laps is 2 laps. Specifically, the test vehicle turns left through the second loop and enters the high-speed loop. After entering the high-speed loop, the test vehicle accelerates to 120 km / h and drives stably for 1 lap, then activates the highway assist system and sets the vehicle speed to 100 km / h, and keeps the vehicle under monitoring. The vehicle continues to drive stably for 2 laps.

[0081] Further, in one embodiment, when the function to be tested is the intelligent speed limit system function, step S10 includes:

[0082] Control the test vehicle to drive on the high-speed loop at a second preset speed for a corresponding number of preset times, where the second preset speed is greater than the speed limit on the high-speed loop;

[0083] In this embodiment, continue to refer to Figure 2 , when the function to be tested is the intelligent speed limit system function, control the test vehicle to drive on the high-speed loop at a second preset speed for a corresponding number of preset times, where the second preset speed is greater than the speed limit on the high-speed loop. At this time, the corresponding number of preset times is 2 times. Specifically, taking the second preset speed of 100 km / h as an example, after the test vehicle enters the high-speed loop monitoring road and maintains a stable speed of 60 km / h and passes through the south bend, it accelerates to 100 km / h and drives stably. After passing the speed limit sign of 60 km / h, the vehicle decelerates to 60 km / h and drives stably for 5 s, and repeats 2 times.

[0084] In one embodiment, when the function to be tested is the traffic congestion assist system function, step S10 includes:

[0085] Control the test vehicle to follow the target vehicle on the high-speed loop.

[0086] In this embodiment, continue to refer to Figure 2 , after activating the traffic congestion assist system and driving stably for 5 s, a static target vehicle is parked about 150 m in front of the test vehicle. After the test vehicle stops for 2 s, the target vehicle accelerates to 60 km / h. After the test vehicle follows the target vehicle through the north bend of the high-speed loop and continues to drive about 200 m, the target vehicle decelerates until it stops. After stopping for about 3 s, it starts to accelerate and changes to the adjacent lane until it passes the high-speed loop entrance again. After repeating the above process 1 time, the vehicle drives out through the high-speed loop exit and enters the second loop.

[0087] Further, in one embodiment, when the function to be tested is the automatic parking assist system function, step S10 includes:

[0088] The test vehicle is controlled to pass through the cement pavement, perforated brick pavement and asphalt pavement on the No. 2 Comprehensive Road, and the automatic parking assistance function is used to park the vehicle on each pavement for the corresponding preset number of times;

[0089] In this embodiment, continue to refer to Figure 2 When the function to be tested is the automatic parking assistance system function, before conducting a durability test on the automatic parking assistance system function, simulate harsh urban driving conditions first. Specifically, the test vehicle starts from the No. 2 Ring Road and enters the No. 2 Comprehensive Road, turns left to enter the serpentine cobblestone road, and drives through the serpentine cobblestone road in a Z-shaped two-lane at a speed of 15km / h with the Z-shaped contour coordinates as the reference point; drives along the monitoring road to the right until the speed limit roadblock, brakes and decelerates to a speed of about 5km / h; passes the speed limit roadblock at a speed of about 5km / h; accelerates to 35-45km / h, passes the damaged bumpy road and manhole cover road; accelerates to 45-50km / h, passes the connecting road, road crown intersection, large road crown road, curved reverse ramp, to Square 4; turns right on Square 4; passes the first section of long wave road at a speed of 45-50km / h; drives to the right after passing the long wave road; drives to the front of the variable wave road, brakes and decelerates and turns left at the same time; drives along the monitoring road to the end of this section of variable wave road, brakes and decelerates, turns right, and then turns left to enter the monitoring road of the next section of variable wave road. Before each section of the wave-changing road, follow the same operation as the previous one; after exiting the wave-changing road, turn left to pass the connecting stone road; pass the monitoring road at a speed of 45km / h; pass the gravel road at a speed of 40km / h; turn right at the 4th square and accelerate to 50km / h, slow down to about 25-30km / h before entering the gravel road; pass the gravel road at a speed of about 25-30km / h; accelerate to 50km / h after exiting the gravel road, drive left to pass the connecting road; before driving to resonance road III, brake with medium intensity, and then turn left (simulating avoidance while driving on the road); accelerate to 50km / h, emergency brake, and repeat twice.

[0090] After the simulation, the durability test of the automatic parking assistance system function was carried out. The test vehicle was controlled to pass through the cement pavement, perforated brick pavement and asphalt pavement on the No. 2 Comprehensive Road, and the automatic parking assistance function was used to park the vehicle on each road surface for the corresponding preset number of times. At this time, the preset number of parking times on each road surface was 6 times. Specifically, the test vehicle was controlled to enter the No. 2 Comprehensive Road Square, and then enter the cement pavement, perforated brick pavement and asphalt pavement respectively, and the automatic parking assistance system function was used to park the vehicle, and each road surface was parked 6 times.

[0093] In this embodiment, continue to refer to Figure 2 , control the test vehicle to enter the door opening warning test area through the Second Comprehensive Road and open the test side door. Then, the target two-wheeler moves parallel to the test vehicle direction at a speed of 15 km / h and overtakes the stationary test vehicle along a straight line, and tests the 4 doors respectively.

[0094] After the 4 doors are tested, the test vehicle drives out of the square, passes through the Second Comprehensive Road and the Second Ring Road, and returns to the test field entrance to prepare for the next round of cyclic test. The total mileage of the durability test is 80,000 km, and each round of cyclic test is about 78 km. The roads for each round of cyclic test are in turn the Second Ring Road, the standard ramp, the straight performance road, the Belgian road, the urban center loop, the Second Ring Road, the high-speed loop, the Second Ring Road, the Second Comprehensive Road, and the Second Ring Road.
