Operating position select device for automatic transmission

摘要

An operating position select device has a select lever unit, a mode shift unit to shift operation modes of the automatic transmission, a mechanically connecting means connecting them, and an assist actuator to assist a select lever. A control unit that controls the actuator is electrically connected to an operating position sensor detecting an operating position of the select lever and an operating velocity detector detecting operating velocity of the lever. The control unit includes a target reaction-force characteristic setting part, a feedback control part determining feedback assist force by multiplying gain by a variation between target reaction force obtained based on the target operating reaction-force characteristic and the operating force obtained based on the operating force signal, and a gain changing part that changes gain used for determining the feedback assist force based on the operating speed signal.
