Control research for hybrid compound braking based on an uncertainty predictive model

For an EV with double driving motors, an uncertainty predictive model was proposed for the hybrid compound braking control system, which has the simple structural characteristics as the parallel system and the controlling advantages as the series system. The distribution coefficients of the braking force were optimized off-line by uncertainty analysis. Then the response surfaces of the distribution coefficients related to the vehicle state were established. The simulation results show that the required braking severity can be well tracked and high performance and reliability of braking stability and regenerative efficiency were obtained.
