Title:
シフトレンジ制御装置
Document Type and Number:
Japanese Patent JP6844492
Kind Code:
B2
Abstract:
A shift range control device includes a drive circuit, a voltage detector, and a controller. The drive circuit includes switching elements, and is shared by a plurality of winding sets. The voltage detector detects terminal voltages of respective phases. The controller controls energization of the winding sets by controlling on and off operations of the switching elements, and controls interruption units each capable of switching between conduction and interruption of power from a power supply to a corresponding winding set. The controller performs disconnection diagnosis based on the terminal voltage during energization of the winding sets in a control state where one of the interruption units is controlled to conduct the power and a remaining interruption unit is controlled to interrupt the power.
