Title:
VEHICLE POWER ASSISTANCE SYSTEM AND VEHICLE DRIVEN WHEEL REGENERATIVE SYSTEM
Document Type and Number:
Japanese Patent JP2018057255
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicle power assistance system capable of performing driving assistance, regenerative braking and power generation by using driven wheels so as to enable improvement of vehicle performance such as traveling performance, braking performance and fuel consumption, simplifying a structure for obtaining auxiliary driving force and suppressing increase in the weight of a vehicle.SOLUTION: A vehicle power assistance system is applied to a vehicle having driving wheels 4 that are not mechanically coupled to a main drive source 5 such as an internal combustion engine. Each of the driven wheels 4 is supported by a wheel bearing 31 mounted with an electric power generator 8 for travel assistance. A rotor of the electric power generator 8 is directly connected to a rotating side ring of the wheel bearing 31 without interposing acceleration/deceleration means. The vehicle power assistance system includes power accumulation means 19 for accumulating regenerative electric power generated by the electric power generator 8 and feeding the accumulated electric power to the electric power generator 8.SELECTED DRAWING: Figure 1
