Abstract
A system and method for starting an engine on a hybrid vehicle includes a motor and an engine coupled to the motor using a clutch. An electrical energy storage device is operatively connected to the motor. The engine is started by decoupling the motor from the engine, and supplying electrical energy from an electrical energy storage device to operate the motor until the motor attains a predetermined speed. The motor is coupled to the engine to transfer kinetic energy from the motor to the engine, and the transferred kinetic energy is used to start the engine.
