Embodiment 1
[0089] Such as figure 1 As shown, a self-driving vehicle test system includes a test site 4, a dynamometer 1, a vehicle under test 6, a communication device 11 and a console 9, and also includes a test background vehicle 3 and an induction magnetic strip 10. The test site 4 is marked with a lane line 2 and three lanes of A, B, and C are established, and the test site 4 is divided into a speed-up area, a speed-maintaining area, and a deceleration area perpendicular to the lane line 2; The induction magnetic strip 10 that is arranged on the B track between the speed maintenance areas is movable; the test background car 3 is located at one end of the test site 4, and is located in the A, B, and C lanes, and the test background car 3 is provided with an induction magnetic strip. The magnetic signal receiver of bar 10; the four-wheel output of the vehicle under test 6 is connected to the dynamometer 1, the vehicle under test 6 is located on the dynamometer 1, and is located at the ...
Embodiment 2
[0095] Such as figure 2 As shown, a schematic diagram of a self-driving vehicle AEBS longitudinal movement state performance test system, the test system includes a dynamometer 1, a test background car 3, a tire speed sensor 8 for measuring the speed of the vehicle tire 7 under test, a communication device 11, an induction The magnetic strip 10 is a magnetic signal receiver for receiving the signal of the induction magnetic strip 10, and the test background vehicle 3 is placed in the B lane. The test here simplifies the scene where the vehicle under test 6 drives towards the background vehicle at a certain speed under normal road conditions, and abstracts the vehicle under test 6 to stand still, but uses the dynamometer 1 to keep the vehicle under test 6 at the speed required for the test. In the mechanical state, the test background vehicle 3 moves towards the tested vehicle 6, thereby simulating the scene where the distance between the two vehicles is continuously shortened...
Embodiment 3
[0117] Such as image 3 As shown, a schematic diagram of an autonomous vehicle AEBS false response test system. Among them, the equipment involved includes: a dynamometer 1, a vehicle under test 6, two test background vehicles 3, a tire speed sensor 8 for measuring the rotation speed of the tire 7 of the vehicle under test, and a tire speed sensor 8 for controlling the vehicle under test 6 and the test background vehicle. 3 The console 9, the communication device 11, the induction magnetic strip 10 and the vehicle-mounted magnetic signal receiver etc. of the corresponding speed.
[0118] combine Figure 5 Understanding a false response test and evaluation method for AEBS of autonomous vehicles, including the following steps:
[0119] Step (S2100) Before the test starts, system initialization and self-testing of various equipment should be carried out. The two test background cars 3 are respectively located at the other end of the two adjacent lanes of the tested vehicle 6, a...
