Abstract:
A transmission control method for a continuously variable transmission for enhancing the response of a change in engine speed to a driver's accelerating/decelerating operation. In a hydraulic type continuously variable transmission, when a sport operating mode is being selected (step S1: SPORT OPERATING MODE), a target engine speed T_NE (rpm) is calculated from the vehicle velocity V (km/hr) and the position θ (degrees) of a throttle valve 60 (step S4). Further, a target angle T_A (degrees) for a motor swash plate is calculated from the vehicle velocity and the target engine speed T_NE (step S5). The motor swash plate is moved according to the difference between the actual angle A of the motor swash plate 46 and the target angle T_A.
