Abstract

Three shafts of a planetary gear mechanism, which is a torque distribution mechanism, are connectable to an engine, a motor-generator and a compressor, respectively. An engine connecting shaft, a motor-generator connecting shaft and an accessory equipment connecting shaft are connected to a ring gear, a carrier and a sun gear, respectively. A single motor-generator can perform four different operations: a compressor driving operation when an idle stop function is performed, an engine starting operation by the motor-generator, a motor-generator driving operation by the engine, motor-generator driving and compressor driving operations by the engine.
