An integrated brake system was put forward, and the dynamic model of the integrated brake system was found to set up its simulation model in computer. Based on the simulation model of the integrated brake system, simulation tests were made under three conditions of high and low adhesions with straight movement and curve movement for the ABS control performances of the integrated brake system in the small electric passenger car. The ABS control performance was described by longitudinal slip of each wheel, the brake torque of each wheel and the longitudinal acceleration of mass center. The driving stability of vehicle was described by longitudinal displacement and slip angle of mass center. The brake energy recovery performance was described by electric power consumption per kilometer. By analyzing the variables characterizing the performances of ABS control, driving stability and brake energy recovery, the research results showed that the integrated brake system with regenerative friction brake in electric vehicle was provided with good braking efficiency, favorable ABS control performance and preferable braking force distribution from front to rear wheels, as well as remarkably improved brake energy recovery rate. Depending on the above results, the suitable advices will be put forward and adopted, which would be helpful for the rapid development of the electric vehicle technology.
