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 apply assist force to a select lever of the select lever unit. A control unit for controlling the actuator is electrically connected to an operating state sensor detecting an operating state of the select lever. The control unit executes assist control to control the assist actuator based on the operating state signal of the operating state sensor, and maintains the assist control for a predetermined period after the ignition switch is turned to OFF.

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.

An operating position select device has a select lever unit, a mode shift unit to shift operation modes of the automatic transmission, and an assist actuator controlled by a control unit. A first connecting member of the select lever and a second connecting member of the mode shift unit are relatively movable to a limit amount to each other and integrally movable beyond the limit amount with each other. The positions of the members are detected by an operating position sensor and an assist position sensor, respectively. The actuator is driven so that a difference between an operating position and an assist position may be reduced, but prohibited from driving when the difference is kept out of a permissible range for a predetermined period during rest of the actuator.

An operation range selection mechanism of an automatic transmission 100 according to the present invention includes an input operation force detector 21 that detects an operation force generated by an operation applied to a select lever 2, an assist actuator 9 that adds an assist force to the select lever 2 to carry out an operation assist for the select lever 2, and an assist force control device 22 that controls the assist actuator 9 to start the operation assist for the select lever 2 upon the value of the operation force detected by the input operation force detector 21 being equal to or more than a predetermined value. The assist force control device 22 stops the operation assist upon the operation force being less than the predetermined value or the select lever 2 having reached a predetermined position, and then temporarily sets the predetermined value to a higher value.
