Abstract:
1. A power transmitting system that is configured to have BAS and IS functionality, the power transmitting system comprising: a first drive assembly having an input member, a first drive member, a second drive member, a first clutch, a second clutch and a third clutch, the input member being adapted to be coupled to an output of an engine, the first clutch being configured to couple the input member to the first drive member when the output member of the engine is driving the input member, the second and third clutches coupling the second drive member to the input member, the second clutch being operable in an engaged mode to transmit rotary power from the input member to the second drive member and a disengaged mode in which the second clutch does not transmit rotary power between the input member and the second drive member, the third clutch being operable in an engaged mode to transmit rotary power in a first rotational direction from the second drive member to the input member and a disengaged condition in which rotary power is not transmitted through the third clutch between the input member and the second drive member; an accessory drive system that is adapted to transmit rotary power to an accessory assembly, the accessory drive system comprising a third drive member, a fourth drive member and a fourth clutch, the first drive member and the third drive member adapted to be coupled via an accessory endless power transmitting member to transmit rotary power therebetween, the third drive member being adapted to be coupled for rotation with an input shaft of the accessory assembly, the fourth clutch being configured to inhibit transmission of rotary power between the fourth drive member and the input shaft of the accessory assembly when the fourth drive member is driven in the first rotational direction, the fourth clutch being configured permit transmission of rotary power between the fourth drive member and the input shaft of the accessory assembly when the fourth drive member is driven in the second rotational direction; and a coupling means that is adapted to couple a shaft of a motor/generator to the second drive member and adapted to couple the shaft of the motor/generator to the fourth drive member.
