Abstract
A method for diagnosing breakdown cause of a vehicle is disclosed. In the method, several sound signals are sensed respectively with several sound sensing devices, which are respectively installed at several zones among the vehicle, from the vehicle. A current driving status of the vehicle is obtained through an electrical control unit (ECU) of the vehicle. Determine a sound source of the vehicle according to the sound signals. A breakdown cause of the vehicle is diagnosed according to the sound signals, the current driving status and the sound source.
