Accessory-driving equipment for an automotive vehicle

Accessory-driving equipment for an automotive vehicle, which connects an engine having an idle stop system, a motor-generator for an electric power generating operation and for an electric motor operation, and an accessory including an air-conditioner compressor that is driven even at a time when the idle stop system is operated, the accessory being driven by the engine when the engine is running and driven by the motor-generator when the idle stop system is operated, the equipment comprising:

• a torque distribution system including a first shaft for connecting to the engine, a second shaft for connecting to the motor-generator, and a third shaft for connecting to the accessory;
• a lock means for locking the third shaft;
• and
• a clutch,
• wherein the clutch disengageably connects any two of the three shafts among the first shaft, the second shaft and the third shaft in the torque distribution system,
• wherein the torque distribution system distributes a torque to the second shaft and the third shaft, the torque being transmitted from the engine through the first shaft, and transmits a torque from the second shaft to the first shaft, and
• wherein the torque distribution system includes a planetary gear system that includes a carrier, a sun gear and a ring gear,
• wherein the first shaft is connectable to the carrier,
• wherein the second shaft is connectable to the sun gear, and
• wherein the third shaft is connectable to the ring gear.
