[0034] Working principle: In the initial state, test vehicle 130, target vehicle 1 200, and target vehicle 2 300 are in the same lane. At this time, the longitudinal movement component 430 is deployed, and the lateral movement component 420 is retracted. By starting the drive device 440, the longitudinal movement component 430 is driven to retract backward, pulling target vehicle 2 300 backward, and test vehicle 130 approaches target vehicle 2 300. At the same time, the longitudinal movement component 430 drives the lateral movement component 420 to deploy to the left, pushing target vehicle 1 200 to the left. At this time, the simulation shows the response strategy and result of test vehicle 130 when it approaches a faulty or slow-moving vehicle and the vehicle in front suddenly changes lanes. In the initial state, target vehicle 1 200 is located on the left. When test vehicle 130 and target vehicle 2 300 are in the right lane, the longitudinal movement component 430 retracts and folds, while the lateral movement component 420 unfolds. By activating the drive device 440, the longitudinal movement component 430 unfolds forward, pushing target vehicle 2 300 forward and increasing the distance between target vehicle 2 300 and test vehicle 130. At the same time, the unfolding of the longitudinal movement component 430 causes the lateral movement component 420 to retract and fold to the right, and the lateral movement component 420 causes target vehicle 1 200 to move to the right between test vehicle 130 and target vehicle 2 300. This is used to simulate the response strategy and reaction of test vehicle 130 when a vehicle in front accelerates and increases the distance between test vehicle 130 and a vehicle in the side lane suddenly changes lanes and cuts in.
