摘要

A hybrid drive system for a motor vehicle, including an engine (12) operated by combustion of a fuel, a first motor/generator (16), a distributing mechanism (20) for mechanically distributing an output of the engine to the first motor/generator and an output member (18, 60), a second motor/generator (22) whose rotary force is transferred to a power transmitting path between the output member and a drive wheel (76) of the motor vehicle, and wherein an engine starting device (42, S3, Q3, R2, SA3) is provided for operating the first motor/generator (16) to crank the engine (12) through the distributing mechanism (20), for thereby starting the engine (12).
