To make electric car have the function of regenerative ABS during regenerative braking on a road of a low tire-road friction coefficient such as the ice-snow covered road,a novel method was proposed that motor regenerative braking and reversal braking torque were controlled to prevent wheels from locking. The working principle of the low-speed regenerative braking as ABS was described,A single-wheel electric car dynamics model in a braking event was built; regenerative ABS controller was designed based on the circuit steady-state conditions of the low-speed regenerative electric motor and fuzzy control theory. Simulation results indicate that this system is of a satisfactory robustness, a much shorter response time and a superior control accuracy. The braking procedure is composed of a regenerative braking action, being of the main part, and an reversal braking action at the end of the braking procedure. Within motor peak working capacity, the greater the road adhesion coefficient ,the more regenerative ABS's amount of recovering braking energy.
