Embodiment 1

[0041] Such as figure 1 and 7 As shown, the front collision avoidance test system based on the distance test, the system includes a target vehicle 1, a test vehicle 2 with the ADAS to be tested installed, and several vehicles installed on the lane 3 for the target vehicle 1 and the test vehicle 2 to drive or park. Sensing device 4, sensing device 4 is longitudinally spaced distribution along lane 3 and this sensing device 4 can produce corresponding sensing signal when target vehicle 1 or test vehicle 2 is positioned at corresponding sensing device 4 position, and sensing device 4 is all connected with signal transmitter 5 Connected and the signal transmitter 5 can receive the induction signal. The test vehicle 2 is installed with the ADAS to be tested and can collect the speed of the test vehicle 2, the sensing time of the corresponding induction device 4 and receive the collision time calculated by the ADAS to be tested. The controller 6 is installed on the target vehicle 1...

Embodiment 2

[0051] Such as figure 2 As shown, the technical solution in this embodiment is the same as that in Embodiment 1, the difference is: in the above-mentioned step B, the distance between each sensing device 4 is s, the target vehicle 1 is driving on the lane 3 at a constant speed, and the test vehicle 2 Driving on the lane 3 at a constant or non-uniform speed and gradually approaching the target vehicle 1, when the target vehicle 1 and the test measurement are located in the test area where the sensing device 4 is installed on the lane 3, the head of the target vehicle 1 reaches the Mth sensing device 4 and the Mth sensing device 4 generates a sensing signal. At this time, the second controller 7 collects the vehicle speed V1 and the sensing time tM of the target vehicle 1 and sends these information to the first controller 6; then the head of the test vehicle 2 arrives The m-th sensing device 4 and the m-th sensing device 4 generate a sensing signal. Similarly, the first contro...

Embodiment 3

[0057] Such as image 3 As shown, the technical solution in this embodiment is the same as that in Embodiment 1, the difference is that in the above-mentioned step B, the distance between each induction device 4 is s, and the target vehicle 1 travels on the lane 3 at a uniform or non-uniform speed, The test vehicle 2 is driving on the lane 3 at a constant speed and gradually approaches the target vehicle 1. When the target vehicle 1 and the test vehicle 2 are located in the test area where the sensing device 4 is installed on the lane 3, the head of the test vehicle 2 reaches the first sensing device 4 and the induction device 4 generates an induction signal and starts timing. When the head of the test vehicle 2 arrives at the nth induction device 4, the first controller 6 collects the vehicle speed V and the sensing time tn of the test vehicle 2; then the target vehicle 1 The head of the vehicle arrives at the mth sensing device 4 and the mth sensing device 4 generates a sens...

The test system is advantaged in that the test system is simple and practical, and high measurement accuracy is realized.

Description

technical field [0001] The invention belongs to the technical field of automobile safety, and in particular relates to a distance test-based front collision avoidance test system and a test method. Background technique [0002] With the development of technology, the field of smart cars has gradually been valued by domestic and foreign technical companies. Therefore, there are many companies developing advanced driver assistance systems (ADAS), but currently there are almost no self-developed test systems in China that can accurately verify ADAS functions. However, there are not many foreign systems that can provide testing ADAS, and the cost is 1.5 million to 2 million. Therefore, in terms of test verification, it is undoubtedly an obstacle for some small-scale companies that develop ADAS in China, and the test cost is high. , the error is large. At present, there is an urgent need for a test system that is simple, practical, economical and has small measurement errors. ...
