摘要:
An electric vehicle includes a motor unit (6) configured to drive a wheel (2), an ECU (21) and an inverter unit (22). A motor control circuitry (29) of the inverter unit (22) includes a rotational frequency controller (37) operable to perform rotational frequency control. The electric vehicle also includes a torque control abnormalities detector (38) configured to detect an abnormality of torque control performed by the motor control circuitry (29). The electric vehicle also includes a control mode switcher (39) configured to, in response to determination by the torque control abnormalities detector (38) that there is an abnormality of torque control, cause the motor control circuitry (29) to switch from torque control to rotational frequency control performed by the rotational frequency controller (37).
