CONTROLLER AND SHIFT-BY-WIRE SYSTEM USING THE CONTROLLER

摘要

A shift-by-wire system, including a controller that includes a motor driver, and a microcomputer connected to the motor driver to control a motor that drives a control object. The control object has a park lock mechanism having a lock state and an unlock state. The lock state and the unlock state are switched according to an operation position of the control object. The controller is configured to estimate a tilt of a vehicle, detect whether the lock mechanism is in the lock state or in the unlock state, and adjust a target rotation speed of the motor according to the estimated tilt when the operation position of the control object is changed for switching the lock state to the unlock state.
