MOTOR DRIVE DEVICE, HYBRID VEHICLE USING THE SAME, AND ELECTRIC POWER CONVERSION DEVICE STOP/CONTROL METHOD

摘要

An ECU (60) activates a shutdown permission signal (RG) and provides it to an AND gate (50) when a shutdown signal (DWN) is inactive. Thus, when an abnormality sensing device (40) does not sense an abnormality, the ECU (60) always keeps the shutdown permission signal (RG) active. The AND gate (50) performs logical AND between a signal (OVL) provided from the abnormality sensing device (40) and the shutdown permission signal (RG) to provide the shutdown signal (DWN) to inverters (20 and 30). When a limp-home run permission signal (BLS) becomes active while the shutdown signal (DWN) is active, the ECRU (60) inactivates the shutdown permission signal (RG).
