<p>The control (60) is for a power train including an engine (10) controlled by a throttle, a friction clutch (20) having an input shaft connected to the engine and an output shaft connected to the input shaft (25) of a transmission (30), and a throttle position sensor producing a throttle signal. An engine speed sensor (13), connected to the engine, generates an engine speed signal. A transmission input speed sensor (31), connected to the output shaft, generates a transmission input speed signal corresponding to the rotational speed of the output shaft. A clutch actuator (27), connected to the friction clutch, controls engagement of the friction clutch from disengaged to fully engaged according to a clutch engagement signal. The control comprises a slip reference generator, responsive to the throttle signal, for producing a slip reference signal which is a function of throttle and engine speed. A circuit produces a slip error signal from the input speed, engine speed, and slip reference signals. A PID regulator, responsive to the slip error signal, regulates the slip error. A control circuit, responsive to the regulated slip error, generates a clutch engagement signal to minimise the slip error signal.</p> |
