Abstract
A control system for a vehicle includes a combustion engine and an electric propulsion system. The combustion engine includes a camshaft and a crankshaft. The control system improves NVH by deactivating the compression pulses during a cranking phase of the combustion engine. A first control module generates a minimum torque, a second control module generates an actual torque and a third control module generates a reference torque. A timing control module generates a timing control output based on the minimum torque, the actual torque and the reference torque. The minimum torque is based on an RPM of the combustion engine, a spark angle and an air per cylinder of the combustion engine. The actual torque is based on an RPM of the combustion engine, a spark angle and an air per cylinder. The reference torque is based on an output of a pedal position sensor.
