[0002] At present, the investment in intelligent driving research and development of vehicles is increasing, and the corresponding test items and test requirements are becoming more and more stringent.

[0034] Working principle: In the initial state, the test vehicle 130, the target vehicle 1 200 and the target vehicle 2 300 are in the same lane. At this time, the longitudinal moving component 430 is unfolded, and the lateral moving component 420 is retracted and folded. By starting the driving device 440, the longitudinal moving component 430 is driven to retract backward, and the target vehicle 2 300 is pulled backward. The test vehicle 130 approaches the target vehicle 2 300, and at the same time, the longitudinal moving component 430 drives the lateral moving component 420 to unfold to the left, pushing the target vehicle 1 200 to move to the left. At this time, the test vehicle 130 is simulated when it approaches a faulty or low-speed vehicle, and the front vehicle changes lanes urgently. The response strategy and response results of the test vehicle 130, while in the initial state, the target vehicle 1 200 is on the left. In the side lane, when the test vehicle 130 and the target vehicle 2 300 are located in the right lane, the longitudinal moving component 430 is retracted and folded, and the lateral moving component 420 is unfolded. The driving device 440 is started to drive the longitudinal moving component 430 to unfold forward, pushing the target vehicle 2 300 forward, and increasing the distance between the target vehicle 2 300 and the test vehicle 130. At the same time, when the longitudinal moving component 430 is unfolded, it drives the lateral moving component 420 to retract and fold to the right, and the lateral moving component 420 drives the target vehicle 1 200 to move right to between the test vehicle 130 and the target vehicle 2 300, so as to simulate the coping strategy and reaction results of the test vehicle 130 when the vehicle in the side lane suddenly changes lanes and squeezes in after the front vehicle accelerates and increases the distance with the test vehicle 130.
