The invention provides an automobile wireless charging foreign matter detection system, which comprises a ground transmitting plate used for transmitting an alternating magnetic field, a vehicle-mounted receiving plate used for receiving the alternating magnetic field and carrying out coupling charging, a foreign matter detection module comprising a plurality of infrared array sensors which are used for detecting the real-time temperature of a wireless charging area between the vehicle-mounted receiving plate and the ground transmitting plate, and a processing unit used for receiving the real-time temperature and outputting a foreign matter detection result indicating that the foreign matter exists in the detection area of the infrared array sensor with the abnormal temperature when the real-time temperature indicates that the temperature is abnormal. The system and the method have the beneficial effects that foreign matter possibly existing between a ground end and a vehicle-mounted end are detected, nine infrared array sensors are used for realizing full coverage of the surface of a ground transmitting plate, and a vehicle-mounted receiving plate can realize full coverage detection when being positioned at any position relative to the ground transmitting plate; and when the infrared array sensors detect the foreign matter, wireless charging is stopped, and the specific position of the foreign matter can be accurately positioned.
