Abstract

This article is concerned with the design of braking control systems for electric vehicles endowed with redundant braking actuators, i.e., with friction brakes and wheel-individual electric motors. Facing the challenge to optimally split the braking torque between these two actuators, a unified model predictive control (MPC) algorithm is presented here. The proposed algorithm unifies the wheel slip controller and the torque blending functions into a single framework. The capability of handling energy performance metrics, actuator constraints and dynamics, represents the main advantages of this approach. Simulation studies demonstrate that, in comparison with state-of-art solutions, the proposed control strategy is able to improve the wheel slip and torque tracking by more than 20%, with minor penalization in the energy recuperation.
