In the embodiment of the present invention, the driving device 1 is used to drive the collision target 2 to move. When the test is carried out, the tested vehicle needs to be accelerated to a preset speed firstly, reaches a preset collision position at the preset speed, and carries out a collision test with the collision target 2, and the optimal state is that the collision target 2 and the tested vehicle reach the test position at the same time, but a certain error range is usually set because the process is difficult to realize. It is to be understood that the "crash" test is generally used to test the validity of the automatic braking system of the vehicle, for example if the vehicle is able to stop by itself before coming into contact with the crash target 2, the automatic braking may be considered valid, and vice versa invalid; therefore, the collision does not necessarily occur actually, and the vehicle under test may stop before the collision occurs. In addition, the synchronous arrival here merely means that when the vehicle automatic braking system does not perform any action, the vehicle to be tested travels at a preset speed to reach the test position, and the collision target 2 also reaches the test position.

Through the arrangement, on one hand, the reaction condition of the automatic brake system when the collision happens to different positions in the width direction of the vehicle head can be tested more accurately, on the other hand, the speed of the collision target 2 is adjusted in real time according to the position and the speed of the tested vehicle in the embodiment of the invention, so that the collision target 2 and the tested vehicle can start to accelerate together, and the running distance of the tested vehicle after the tested vehicle reaches the preset speed can be achieved in the mode, and the test can be carried out in a smaller field.
