摘要： PROBLEM TO BE SOLVED: To omit a wire harness such as a power cable, etc., and improve power loss, in a vehicle driving system of engine/electric motor composite type. SOLUTION: Part 1 of wheels are driven with an engine 3. Wheels 2 other than the wheels driven with the engine 3 are driven with a dynamo-electric machine 4. The dynamo-electric machine 4 is driven as an electric motor for wheel drive to assist an engine drive system when the travel load is as large as that at start or at climbing up a slope. In vehicle drive, there is an operation range where it does not need electric assistant drive such as the time of low/middle load travel or deceleration. At this time when the assistance is needless, the dynamo-electric machine is functioned as a generator so as to convert the mechanical energy from the wheels into electrical energy. The dynamo-electric machine 4, an inverter 7, a capacitor 11, and a controller 18 are unitized integrally, and the unit is attached to a differential gear 5. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a drive system to constitute a four-wheel drive vehicle using a motor, without using expensive parts such as an inverter. SOLUTION: This invention eliminates an inverter by directly supplying the ac power to a motor 2 without rectifying the output of a generator 1. In addition to that, this invention makes the output voltage of the generator 1 variable by adjusting the field current, and uses an induction motor 2 for a motor to obtain the same motion as by an inverter since the torque speed is variable following the input voltage.

摘要： PROBLEM TO BE SOLVED: To attain omission of a wire harnesses, such as a power cable, and improvement in power loss, in a vehicle driving system of an engine/motor hybrid type. SOLUTION: Portions 1 of wheels are driven by an engine 3. Wheels 2, other than the wheels driven by the engine 3, are driven by a rotary electric machine 4. When a running load is large, such as at starting and going up a slope, the rotary electric machine 4 is driven as a motor for driving the wheels to assist an engine drive system. In driving a vehicle, there exists a driving region requiring no motor-driven assist, such as low/medium load running and at speed reduction. When such an assist is not required, the rotary electric machine is caused to function as a power generator, and mechanical energy from the wheels is converted into electrical energy. The rotary electric machine 4, an inverter 7, a capacitor 11 and a controller 18 are integrally formed as a unit, and is fitted to a differential gear 5. COPYRIGHT: (C)2006,JPO&NCIPI
