The invention provides a vehicle alignment guidance system and method for a wireless charging system, and relates to the field of wireless power. The system comprises a ground charging terminal provided with at least one target and a vehicle-mounted controller. The vehicle-mounted controller is connected with a vehicle-mounted rearview camera, a vehicle-mounted charging terminal and the ground charging terminal; and the vehicle-mounted controller comprises a processing module used for processing a target image to obtain a first distance between the vehicle-mounted rearview camera and the target, and a comparison module connected with the processing module and used for comparing the first distance with a preset interval threshold value. The ground charging terminal comprises a signal transmission module which is used for outputting a transmitting signal and then detecting a beacon signal obtained by the vehicle-mounted charging terminal according to the processing of the transmitting signal in real time, and a signal processing module that is connected with the signal transmission module and used for performing processing according to the beacon signal to obtain the relative position between the vehicle-mounted charging terminal and the ground charging terminal and generating second alignment prompt information. According to the invention, the positioning precision of the vehicle in long distance, short distance and short distance is effectively improved, and the use cost is reduced.
