Abstract: PROBLEM TO BE SOLVED: To provide a motor drive controlling equipment in which the number of current sensors is reduced. SOLUTION: A phase current is supplied to 3-phase coils Y1 and Y2 from inverters INV1 and INV2. Four current sensors are usually required to detect two phase currents for the 3-phase coils Y1 and Y2. However, the number of phase currents to be detected is reduced by estimating the phase current using an observer. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To more appropriately meet requests to different shafts on the same axis for power. SOLUTION: Requests for power of low-revolution, high-torque are made to a ring gear shaft 32a, and requests for power of high-revolution, low-torque are made to a sun gear shaft 31a. To cope with this, a multilayer motor 40 is constituted which consists of a high-revolution, low-torque motor MG1 comprising a rotor 41 and a stator 42 and placed on the inner radius-side one of the circumferences of concentric circles; and a low-revolution, high-torque motor MG2 comprising a rotor 44 and a stator 45 and placed on the outer radius-side one. The crank shaft 26 of an engine 22 is coupled with the carrier 34 of a power transfer and integration mechanism 30. The motor MG1 is coupled with the sun gear 31, and the motor MG2 is coupled with the ring gear 32. The engine 22, motor MG1, and motor MG2 are operated and controlled so that power requests from the driver are outputted to the ring gear shaft 32a. Thus, a multilayer motor 40 wherein requests to different shafts for power can be more appropriately met is obtained. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To support a motor generator with high accuracy without being influenced by the centering accuracy of a crankshaft of an engine and transformation of a torque converter, to improve efficiency of the motor generator, and to miniaturize thereof. SOLUTION: A motor housing 15 is disposed between a converter housing 12 and an internal combustion engine 13, and a bearing 47 is fitted to a side wall 15a provided at a front part of the motor housing. Rotor supporting members 45, 49 are independently supported by the bearing. Eccentric rotation accompanying the explosion vibration of the crankshaft 52 is absorbed by two flex plates 55, 51, and the transformation of the torque converter 5 does not have influence on the rotor supporting member 45 with separate structure due to clearance c provided therebetween.

Abstract: PROBLEM TO BE SOLVED: To perform quick acceleration when a deceleration demand condition is released. SOLUTION: When a car runs by following a preceding car, and then the preceding car does not exist (S11-S15), output torque is operated from an acceleration demand at that time (S16). The output of a motor generator is controlled and the output of an engine is increased (S17, S18). After a specified time has passed (S19), ordinary throttle control is performed (S20), and the output of the motor generator is stopped (S21). Quick acceleration can be obtained by using torque assist of the motor generator.
