Compared with traditional vehicle, hybrid electric vehicle (HEV) is a more complicated system. With a series of high voltage components, HEV has an increasing failure rate. In order to detect the possible fault, a fault detection for HEV is proposed. The fault detection is conducted in three aspects, namely input signal of main components, torque response of power sources and logical rationality of key signals. Then time based fault confirmation mechanism is used to confirm the detected fault. Finally, hardware in the loop test result shows that the proposed method is able to detect faults rationally.
