Abstract: A vehicle inspection system is described. The vehicle inspection system comprises: an inspection device, for performing an inspection on a vehicle to be inspected; a carrier platform, for carrying the vehicle to be inspected; and an unmanned controlled travelling device for moving the carrier platform to pass through a scanning area of the inspection device, so as to perform the inspection on the vehicle to be inspected. In the present disclosure, the vehicle to be inspected is carried by the carrier platform, and the unmanned controlled travelling device is used to move the carrier platform to pass through the scanning area of the inspection device, so that the vehicle to be inspected can be subject to inspection smoothly. There is no driver required to drive through the scanning area in this process, thus avoiding exposure of a driver to a threat of radiation.
