The support device is arranged on the test platform. The test device is connected to a controller, the controller is used to control the operation of the test device, and the test device is used to test the vehicle carried by the support device.

[0060] In a specific application scenario, when a vehicle is placed on a test platform, the parameters of the vehicle are input into the terminal, and the controller adjusts the support device based on these parameters to adapt to specific vehicles and test conditions. For example, for heavy vehicles, the controller controls the drive member to drive the first support member 22 and the second support member 23 to move in opposite directions, and controls the motor 320 to drive the support plate 31 to move in a direction close to the vehicle, so that the support device automatically unfolds into a more solid and wider form to provide better stability; for light vehicles, the controller controls the drive member to drive the first support member 22 and the second support member 23 to move in opposite directions, and controls the motor 320 to drive the support plate 31 to move in a direction close to the vehicle, and when supporting a light vehicle, the upper surface of the support plate 31 is lower than the upper surface when supporting a heavy vehicle, so that the support device is adjusted to a more compact and flexible form. After adjustment, the controller controls the test device to test the vehicle, and during the test, receives data from various sensors, and adjusts the support device in real time to ensure the reliability of the test.

[0061] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
