Abstract
The present disclosure generally relates to operating an electric vehicle (EV) during a fault condition. The EV drive system comprises a motor configured to provide motive force to the EV. The EV processing system can to run a diagnostic routine to monitor the drive system for the fault condition. In response to identifying that the drive system is in the fault condition, the processing system can determine whether the fault condition was caused a three-phase short circuit or a three-phase open circuit. The processing system can estimate a motor torque for the motor based at least partly on the motor speed and on whether the fault condition was caused by the three-phase short circuit or the three-phase open circuit, and can use the estimated motor torque to control the drive system to provide motive force to the EV while operating in the fault condition.
