Abstract:
1. A vehicle electric motor diagnosing apparatus for a vehicle having a generator driven by a drive torque of a drive source, an electric motor driven by electric power supplied from the generator, and a wheel driven by the electric motor, the electric motor diagnosing apparatus comprising: a counterelectromotive force determining section configured to determine whether a voltage of electric power supplied from the generator to the electric motor is greater than an induced voltage of a counterelectromotive force of the electric motor; and an electric motor diagnosing section configured to drive the electric motor by controlling the generator to supply the electric power to the electric motor, and determine whether the electric motor is rotating, upon the counterelectromotive force determining section determining that the voltage of the electric power supplied from the generator to the electric motor is greater than the induced voltage of the counterelectromotive force of the electric motor.
