Abstract
An apparatus for controlling a gear ratio changing operation in a transmission includes clutch controlling device, a motor generating an assist driving torque, and an assist driving torque controlling device for controlling, in response to a clutch operation, the motor to generate a target assist driving torque. While transmission of driving torque between an internal combustion engine and the transmission is being cut off during a clutch control at a constant stroke speed from an engaged state to a disengaged state for a shift operation in the transmission, the assist driving torque controlling device controls the motor to generate an assist driving torque so that the assist driving torque reaches the target assist driving torque at a constant rise rate per time.
