Abstract
A system (40) for an automotive vehicle (10) has an internal combustion engine (12) having a crankshaft (50) and a starter/alternator (42) coupled to the crankshaft (50). A transmission (26) is coupled to the starter/alternator (42). A gear position sensor (70) coupled to the transmission (26) generates a gear change signal. A controller (54) is coupled to the starter/alternator (42) and the gear position sensor (70) and receives the gear change signal. The controller (54) initiates the operation of the starter/alternator (42) as a motor to provide a predetermined torque.
