The invention discloses an automatic vehicle tire identifying and positioning system and method. The automatic vehicle tire identifying and positioning system comprises tire pressure sensors, a controller, a receiving box and a calculating unit. The controller is installed on a vehicle front axle and receives tire pressure sensor data of tires on the axle. The receiving box is installed on anothertire of the vehicle and receives the tire pressure data of the tires on the axle. The receiving box is connected with the controller to send the obtained tire pressure data to the controller. The calculating unit samples and calculates the quality of a radio-frequency signal sent by each tire pressure sensor on any one side of the axle where the controller or the receiving box is located. LF initiation antenna of the controller and the receiving box are both installed beside the tires on the same side of the vehicle and used for sending an initiation instruction to the tire pressure sensors.The automatic vehicle tire identifying and positioning system and method achieve automatic positioning of the positions of the sensors by means of the LF receiving function of the tire pressure sensors and the method of analyzing the signal quality of the tire pressure sensors.
