CROSS REFERENCE TO RELATED APPLICATION

The present application claims the benefit of priority from Japanese Patent Application No. 2019-096129 filed on May 22, 2019. The entire disclosure of the above application is incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a shift range control device.

BACKGROUND

A shift range control device for switching a shift range by controlling driving of a motor has been proposed. For example, in a comparative example, when driving of the motor is controlled by one of two microcomputers, and an abnormality occurs in the microcomputer used for drive control of the motor, the microcomputer used for drive control of the motor is switched to another microcomputer.

SUMMARY

A shift range control device may include: multiple controllers that may communicate with each other and control driving of a motor. The multiple controllers may share control information, and include a first controller and a second controller. When the control information of the first controller may be different from the control information of the second controller, one of the first controller and the second controller may be set as a continuation controller, and a different one of the first controller and the second controller may be set as a stop controller. The stop controller may stop the drive control.

The continuation controller may perform the drive control of the motor.
