Abstract:
An electronic control unit diagnoses a short failure of an inverter FETs and diagnoses whether the failure of the FET-short detecting section has occurred. The unit controls a motor through an inverter including a bridge having an upper-stage FETs and a lower-stage FETs via an MCU, having: an FET-short detecting section to detect a short failure of the upper-stage FETs and the lower-stage FETs based on respective connection point voltages of the upper-stage FETs and the lower-stage FETs; and a diagnostic function to detect a failure of the FET-short detecting section. The diagnostic function diagnoses the failure of the FET-short detecting section at start up and turns-OFF the upper-stage FETs and the lower-stage FETs when the failure is detected. The FET-short detecting section diagnoses the short failure of the upper-stage FETs and the lower-stage FETs when the failure of the FET-short detecting section is not detected.

Claim (Index 5):
The electronic control unit according to  claim 1 , wherein said FET-short detecting section notifies said error notification to said MCU via an NDIAG terminal when said short failure is detected, said MCU sends an error signal to an alarm input circuit, and said alarm input circuit turns-OFF said upper-stage FETs and said lower-stage FETs by inputting a gate-OFF command into said gate driving section.
