Abstract
A hybrid system for a vehicle which can ensure a braking stability on a slippery road is provided. Therefore, the system is provided with a motora rotation force of which is transmitted to a rear wheel, braking actuatorswhich brake the front wheeland the rear wheel, and proportional valvescontrolling a braking force introduced into each braking actuator. A control unitis so provided that the control unitcalculates a required braking energy based upon a vehicle operating condition in demanding a braking and operates the motoras a power generator to generate a power so as to produce the calculated braking energy, as well as controls a braking force of the front wheel
