制御装置。[Claims for Utility Model Registration] A gearshift actuator that operates in response to a given gearshift command signal, and a gearshift command member that is displaced by the operation of the gearshift actuator, and the gear ratio is determined according to the displacement of the gearshift command member. In a speed change control device for a continuously variable transmission, the speed change actuator and the speed change command member are both forcibly displaced to the larger speed ratio side when the select lever is switched from the normal driving range to the engine braking range. The vehicle is characterized by being provided with an overspeed prevention device that operates the speed change actuator to a smaller speed ratio side when the engine rotational speed exceeds a permissible value due to the speed change caused by the displacement of the speed change command member. Shift control device for continuously variable transmission.
