ENGINE CONTROL APPARATUS

An engine control apparatus determines that a piston is at a compression top dead center immediately before engine speed of an engine becomes zero if of the engine speed at the compression top dead center of the engine in a rotation drop period while the engine speed drops to zero after combustion of the engine is stopped. In the case where it is determined that the piston is at the compression top dead center immediately before the engine speed of the engine becomes zero, the engine control apparatus applies counter torque by the rotating electrical machine from the compression top dead center to stop the piston at a rotation angle position in a first half period of expansion process by application of the counter torque.
