Abstract

A control system for a starting clutch installed in an automotive vehicle. The starting clutch is arranged between the engine and at least one wheel of the vehicle, for controlling engagement between the engine and the at least one wheel. A basic torque capacity of the starting clutch is calculated based on the rotational speed of the engine, and a torque capacity correction value is determined such that it assumes a minimal value when a clutch speed ratio of the starting clutch detected by a clutch speed ratio sensor is equal to 1.0 and progressively increases as the clutch speed ratio increases and decreases from 1.0. The determined torque capacity correction value is changed based on the throttle valve opening, and the torque capacity of the starting clutch is determined based on the changed torque capacity correction value and the calculated basic torque capacity.
