Finally, unlock each roller body 210 through the roller locking device 400. The test vehicle 300 can be tested on the vehicle's original car test equipment of the application. The rotating support roller set 200 provides rotating support when the test vehicle 300 travels at different speeds. The rotating support of the rotating support roller set 200 ensures that the test vehicle 300 can simulate driving at different speeds on the device. The traction limiting device 500 pulls the test vehicle 300 to limit the movement of the test vehicle 300 and prevent the wheel body 310 of the test vehicle 300 from driving out of the rotating support roller set 200.
