Abstract
A shift range control device is provided for a shift range switching system that includes a motor having winding sets and a motor rotational angle sensor. The shift range control device includes controllers configured to control switching of a shift range by controlling drive of the motor. Each of the controllers is provided to corresponding one of the winding sets, and is configured to acquire a motor rotational angle signal from the motor rotational angle sensor and calculate a motor angle, control drive of the motor by controlling a current supply to the corresponding one of the winding sets to make the motor angle become a target rotational angle corresponding to a target shift range, and drive the motor by sequentially switching a current-supplied phase for each predetermined period without using the motor rotational angle signal when the motor rotational angle signal is in fault.
