PURPOSE:To improve the drive feeling by squeezing a throttle by predetermined amount when transferring from torque converter state to lockup state thereby reducing the output torque by predetermined amount. CONSTITUTION:Upon provision of a signal for transferring the coupling condi tion of transmission from torque converter state to lockup state through an electronic controller 4, the lockup oil pressure will rise with come lag to start lockup operation. Upon finish of lockup, the engine torque DELTAT will rise thereby a throttle actuator 12 is functioned simultaneously with lockup to reduce incre ment of torque thus to finish throttling. Consequently, variation of torque to be transmitted to the drive wheel is prevented resulting in prevention of impact upon lockup. |
