Abstract
A system and method for controlling engine starting in a hybrid electric vehicle that includes a battery, an engine and a generator acting as a motor control generator power during engine starting so that generator torque complements or assists the engine to develop a stable running speed throughout an engine start event, particularly a cold engine start event, without violating battery power limits.
