A Composite ABS Control Method for EV with Four Independently-Driving Wheels

A new composite ABS control method for EV with four independently-driving wheels is presented. Combinating the best braking energy recovery strategy and the ideal braking force distribution control strategy, we designed a new strategy of braking force distribution for EV with four independently-driving wheels, and proposed a new composite ABS control method based on cooperative work of electric motor ABS and hydraulic ABS. A co-simulation model was built with AMESim and Simulink/Stateflow, and simulation was carried out. Simulation result indicates that the new control method can satisfy the braking requirements and improve the braking stability, and it could be a developing direction of EV ABS system.
