| Abstract | Proposed a composite ABS control method for vehicles with four electric wheels, and simulated the method. By analyzing the characteristic curves of the four in-wheel electric motors, and some typical braking force distribution methods of composite braking for EV, a braking force distribution method for four-electric-wheel EV is presented. The method combined the ideal braking force distribution curve, and considered the ECE braking regulations, so it can guarantee both the braking stability and the energy recovery. Furthermore, a composite ABS control method was proposed base on the braking force distribution method. The composite ABS control method is a control method that the electric motor ABS control works together with the hydraulic ABS control. Both of the two modes of ABS control logic were using logic threshold control method. The model of the electric-wheel vehicle were established with AMESim, and the model of the composite ABS controller were built with Simulink. Co-simulation were carried out. Through analysis, a number of parameters curves were obtained. It proves that the composite ABS control method for four-wheel electric vehicles can effectively control the slip rate, and ensure braking stability. |
