Electric vehicle with ABS braking

摘要

An electric vehicle with front wheel drive has regenerative brake control, to prevent the regeneration whilst the ABS system is active. When the ABS system is inactive, the control system combines the "mixing brake torque" and the friction torque into a common brake torque in order to save electrical energy and when the ABS system is activated, the component of regenerative braking is slowly reduced to zero, to maintain soft braking. When the ABS system is active and the front wheels are on a low friction road surface, the control system eliminates the total regenerative torque.
