Abstract:
A drive device includes a motor, an inverter, and a rotation angle detector. The rotation angle detector includes a resolver and an electronic control unit. The electronic control unit converts a signal from the resolver to a master rotation angle of the motor. The electronic control unit converts a signal obtained by attenuating a high frequency component of a frequency higher than a predetermined frequency with respect to the signal from the resolver to a slave rotation angle of the motor. The electronic control unit determines that the master rotation angle is normal when a determination condition that a difference between the master rotation angle and the slave rotation angle is equal to or greater than a first threshold and a temporal variation as a variation of the master rotation angle per unit time is equal to or greater than a second threshold is not established.

Claim (Index 1):
A drive device comprising:\n a motor; inverter configured to drive the motor with switching of a plurality of switching elements; and a rotation angle detector configured to detect a rotation angle of the motor, the rotation angle detector including a resolver and an electronic control unit, wherein: the resolver is attached to a rotational shaft of the motor and is configured to output a signal according to rotation of the motor; the electronic control unit is configured to convert a signal from the resolver to a master rotation angle of the motor; the electronic control unit is configured to convert a signal obtained by attenuating a high frequency component of a frequency higher than a predetermined frequency with respect to the signal from the resolver to a slave rotation angle of the motor; and the electronic control unit is configured to determine that the master rotation angle is normal when a determination condition that a difference between the master rotation angle and the slave rotation angle is equal to or greater than a first threshold and a temporal variation as a variation of the master rotation angle per unit time is equal to or greater than a second threshold is not established and determine that the master rotation angle is abnormal when the determination condition is established.
