ABSTRACT:
A system and method for controlling the ignition timing of a spark ignition internal combustion engine in a driveline that includes a multiple speed ratio transmission, at least one of whose operating speed ratios depends on the engaged or disengaged state of a clutch, the rotating inertia of the engine, equivalent vehicle inertia, a spring associated with the stiffness of the axle, inherent structural damping, and a spark advance controller-filter, whose output advances and retards the spark timing of the engine in accordance with the magnitude of engine speed and transmission output speed according to a control algorithm, which improves speed ratio control during shifts and minimizes the underdamped oscillations that result after the clutch is fully engaged.
