A vehicle drive system includes a motor (drive motor), a generator, a reduction drive that reduces output of the motor, and a housing. At a position above a motor shaft, an oil passage, through which oil is supplied to each of the motor, the reduction drive, and the generator, is integrally formed with the housing. An oil pipe is attached to the housing and supplies the oil from an oil reservoir to the oil passage. At a position between the motor and the generator, the reduction drive is offset from the motor shaft in a second direction that is orthogonal to the first direction. The oil pipe is located between the motor and the generator in the first direction, and at least part of the oil pipe is located on an opposite side of the reduction drive with the motor shaft being interposed therebetween in the second direction.

Vehicle drive system

A vehicle driving apparatus is provided that includes a drive motor, an internal combustion engine, and an electrical generator and can inhibit a weight balance and motion performance of a vehicle from being deteriorated and lowered. A vehicle driving apparatus driving a vehicle by motive power of a motor, the vehicle driving apparatus including a drive motor that is driven by electric power, an internal combustion engine that produces motive power by fuel, and an electrical generator that is driven by the internal combustion engine, the vehicle driving apparatus being characterized in that the drive motor, the internal combustion engine, and the electrical generator are arranged in a vehicle width direction of the vehicle in order of the drive motor, the internal combustion engine, and the electrical generator.

Vehicle driving apparatus

A power train support structure includes a first front side frame disposed on one of left and right sides of a power train; a second front side frame disposed on the other of the left and right sides of the power train, and being greatly away from the power train with respect to the first front side frame; a mounting bracket having one of left and right ends connected to the power train; and a connecting member for connecting the mounting bracket and the second front side frame. The mounting bracket includes a front fixing portion and a rear fixing portion to be fixed to the power train. A strength of the front fixing portion and the rear fixing portion is set to such a strength that the rear fixing portion is broken by a collision load from a front side, and the front fixing portion is not broken.

Power train support structure for vehicle

In an electric vehicle inverter apparatus, a vehicle control controllerdetects a switch open signal output from a collision detectorwhen the collision detectoris caused by a collision between electric vehicles to operate. Then, an inverter main circuit connection switchof a high-voltage battery unitis put into an open state. Thus, the direct-current power supply from a high-voltage batteryto a DC bus portion is interrupted. In addition, electric charges charged into a main circuit capacitorare discharged by a forced discharge circuit portion

Electric vehicle inverter apparatus and protection method therefor

A hybrid vehicle includes: first and second rotary electric machines; a matrix converter connecting the first and second rotary electric machines to each other to provide AC to AC power conversion between both the rotary electric machines; a battery connected to an electrical path branched off between the matrix converter and the second rotary electric motor; an inverter interposed among the battery, the matrix converter and the second rotary electric machine to convert AC power to DC power and vice versa; and a controller. The controller activates the first rotary electric machine with power fed from the battery and restrains the change in torque output of the second rotary electric machine at the activation of the first rotary electric machine.
