Driving-power control device for vehicle

摘要

Since a power of an engine is transmitted to a first axle and a power of a MG is transmitted to a second axle, a space for providing the MG can be readily ensured. Further, since an accessory is driven by the power of the engine, a private power source for the accessory is not necessary. In this case, the accessory may be a water pump, an oil pump, or an air-conditioner compressor. Furthermore, since a vehicle driving mode is switched between an engine driving mode and a MG driving mode, only a control system relative to the MG driving mode is necessary to be developed when the hybrid vehicle is developed by using the engine vehicle as the base part.

主权项

1. A driving-power control device for a vehicle equipped with an engine and a motor as power sources, the driving-power control device comprising:
an axle to which a power of the engine and a power of the motor are transmitted in parallel; at least one of a water pump, an oil pump, and an air-conditioner compressor, which rotates synchronously with the engine; a control portion switching a vehicle driving mode between an engine driving mode that the axle is driven by the power of the engine and a motor driving mode that the axle is driven by the power of the motor; and a motor-side clutch which blocks or allows a power transmission between the motor and the axle, wherein the control portion opens the motor-side clutch in the engine driving mode.
