Abstract

A transmission system for optimally re-engaging a shift clutch irrespectively of running conditions of the vehicle. In the transmission system for a vehicle in which a shift clutch is actuated interlockedly with a shift spindle rotationally driven by a shift motor, a target clutch torque for the shift clutch is calculated based on an estimated engine torque derived from an estimated engine torque map which prescribes the relation between engine rotational speed, throttle angle, and estimated engine torque, and a target shift spindle angle is calculated based on a value derived from a target shift spindle angle map which prescribes the relation between the target clutch torque and the target shift spindle angle. A control unit controls the shift motor based on the target shift spindle angle calculated by a target shift spindle angle calculator, at the time of effecting a gear shift of a transmission.
