摘要:
The present invention relates to a further improvement of the running performance of the vehicle. This object can be solved by providing a rollback controller (150) used for controlling the operation of an inverter (400) to control an armature current of the motor (500) in a motor control equipment (120) so that, when a rollback is detected and a rollback speed exceeds a rollback speed limit, the rollback is maintained and the rollback speed is limited by the driving force of the motor (500), with the rollback speed limit value as a target speed recognized.

The invention relates to a motor control apparatus and on-vehicle motor drive system which can easily protect components of an inverter 32 from overvoltage even if surplus power occurs in a generator 21 in a system without a battery between a generator and a motor. The inverter 32 converts the DC power generated by a generator 21 to AC power, and supplies it to an AC motor 40. A controller 100 controls DC-to-AC conversion in the inverter 32. Interruption means including an overvoltage detector 36 and a semiconductor switch 38 prevents the power generated by the generator 21 from being supplied to the inverter 32 when the inverter 32 is stopped.
