<p>An automatic clutch controller for a vehicle that reduces the oscillatory response to clutch engagement. The automatic clutch controller receives inputs from an engine speed sensor (13) and a transmission input speed sensor (31) and develops a clutch actuation signal controlling a clutch actuator (27) from disengaged to fully engaged. The clutch engagement signal at least partially engages the friction clutch (20) in a manner to cause the measured transmission input speed to asymptotically approach engine speed employing an approximate inverse model of this oscillatory response. The automatic clutch controller preferably includes a PID function and a differential engine speed function, which together adaptively adjust clutch engagement corresponding to vehicle loading. The automatic clutch controller includes a PID regulator (65) responsive to the difference of engine speed and transmission input speed, a prefilter (68) operating on the resulting PID signal, and a compensator (70) constructed to reduce the need for detailed particularization for individual vehicles or vehicle models by reducing the system closed loop sensitivity to vehicle parameter variations.</p> |
