Abstract

Systems and methods for controlling stopping position of a crankshaft during shutdown of an internal combustion engine control a fluid pressure to control a corresponding drive torque of a fluid pump. Kinetic energy of the engine at shutdown may be used to control fluid pressure in a power steering system or fuel injection system to stop the crankshaft in a position favorable for restarting.
