摘　　要：提出电动汽车再生摩擦集成制动系统,建立了集成制动系统动力学模型和仿真系统;针对小型电动乘用车,分别在高附着路面直行、低附着路面直行、高附着弯道行驶3种典型工况下,对集成制动系统进行ABS性能仿真试验研究。研究中,以各轮制动转矩、滑移率和质心纵向加速度表征ABS控制性能参数,以纵向位移和质心侧偏角表征车辆行驶稳定性参数,以制动能回收率表征车辆能量回馈性能参数。研究结果表明,电动汽车再生摩擦集成制动系统具有较高制动性能、良好的ABS控制性能及较好的前后轮制动力分配性能,同时显著提高了制动能回收率。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.
