Filed: 2020-10-06
Abstract: To provide a technique for preventing unnecessary torque from occurring in a motor when any one of three current sensors for current feedback becomes unavailable and an unusable current sensor is specified.SOLUTION: An electric vehicle disclosed in the present specification has a motor for traveling, an inverter supplying AC to the motor, three current sensors, and a controller. The three current sensors measure respective currents of three-phase AC output from the inverter. The controller controls the motor through the inverter. The controller, when any one of the current sensors becomes unavailable, controls the motor by setting a d-axis voltage command value zero and a q-axis voltage command value non-zero, and specifies the current sensor which becomes unavailable. By controlling the motor (inverter) by setting the d-axis voltage command value zero and the q-axis voltage command value non-zero, a current flows through the motor and no torque occurs.SELECTED DRAWING: Figure 1
