The paper introduces the anti-lock braking system (ABS) designed for the all-wheel drive full electric vehicle equipped with four on-board motors. The main features of the ABS under consideration are (i) continuous wheel slip control with feedforward and feedback controller parts, and (ii) versatile actuation architecture realizing pure electric braking, braking with electro-hydraulic decoupled brake systems, and blended braking with operation both of friction brakes and electric motors in regenerative mode. Results of ABS validation demonstrate essential benefits of the developed control strategy for brake performance, precise wheel slip tracking, and drive comfort at braking. Adaptive properties of the proposed ABS are discussed for test cases including the transient road friction.
