Abstract:
A shift range control device, mounted on a vehicle for switching a shift range by controlling a driving operation of a motor, includes: feedback controller; a feedback value setting unit; a current sensor; and a current correction unit. The feedback controller performs a feedback control based on an actual angle of the motor and a motor speed as a rotational speed of the motor. The feedback value setting unit sets a feedback value of the motor speed to advance a phase of the motor speed, based on the motor speed. The current sensor detects a motor current which flows through the motor. The current correction unit estimates a temperature of the motor based on the motor current, and corrects a target motor speed which is a target speed of the motor determined based on a request shift range.
