| ABSTRACT |
|
This paper reviews fault diagnosis and tolerant techniques for improving reliability of automotive motor
control systems which consist of an inverter, permanent magnet synchronous motor and sensors. In order to improve
reliability of system, the fault diagnosis is the first step once a fault occurs. An accurate and timely detection and protection
can prevent fault propagations and catastrophic consequences. The fault tolerant operation is the next counter measure, which
is based on redundancy design. In this paper, statistical survey results on occurrence and failure rate of common fault modes
are summarized for inverter, electric motor and sensors, respectively. And then, fault diagnosis and tolerant methods for the
main fault modes are discussed based on the researches and literatures which are adequate for automotive applications.
Finally, a reliability assessment methodology according to fault mitigation and tolerant concepts is introduced and discussed. |
