Abstract

The torque of an internal combustion engine is controlled during acceleration by monitoring differences between engine and wheel speed in order to provide a measure of phase differences in the event of the engine torque oscillating. The difference between the engine and wheel signals is integrated and fed to an ignition angle correction circuit in order to damp out the torque oscillations which would otherwise result.
