METHOD AND APPARATUS FOR BRAKING ELECTRIC VEHICLE

摘要

PROBLEM TO BE SOLVED: To efficiently recover the energy at the time of regenerative braking while assuring the traveling stability of a vehicle. SOLUTION: At least at the time of initial braking, the hydraulic braking of drive wheels 4 which make it possible to be connected to a motor 6 and driven with a battery 8 as an energy source and hydraulically braked and regeneratively braked by the operation of a brake pedal 18 and the hydraulic braking of driven wheels 2 which make it possible to be hydraulically braked by the operation of the pedal 18 are inhibited, and the regenerative braking of the drive wheels 4 are operated. When the regenerative brake forces of the drive wheels reach a predetermined value BE1 of less than the maximum value, the hydraulic braking of the wheels 2 is started, and the brake force distribution of the wheels 2 and 4 is brought into coincidence with the preset ideal distribution approximate characteristics before the regenerative brake force of the wheels exceeds the maximum value.
