| Abstract(E) | When applying position sensorless control to a generator motor in a 100% electric-drive hybrid vehicle, handling transient estimation abnormalities is an important issue. This study proposes an abnormality detection method based on the rate of change of estimated speed and current, along with a recovery method combining gate-off and three-phase short-circuit control. The method achieves both overcurrent suppression and vibration reduction while enabling restart. Its effectiveness is verified through vehicle experiments. |
