【摘要】：【目的】为了提高电动商用车复合制动系统的能量回收率、改善制动感觉.【方法】依据ECE法规、电机、蓄电池和制动感觉等约束条件的限制,结合电动商用车电-气复合制动系统的特点,提出了一种最佳感觉的串联制动控制策略,根据制动强度和I曲线分配电机和气压制动力,并在Cruise与Matlab联合仿真环境下建立制动控制策略模型,通过60km/h初速一次制动工况和NEDC循环工况验证串联制动控制策略的性能.【结果】在具有最佳制动感觉的同时,z=0.1和z=0.5一次制动工况下制动能量回收率分别达到了19.43%和17.39%,NEDC工况下能量回收率达到了18.56%.【结论】电动商用车串联制动控制策略能够在保证最佳制动感觉的前提下大大地提高制动能量回收率,是一种提升电动汽车制动性能和整车经济性的有效方法.
[Abstract]:[objective] in order to improve the energy recovery rate of electric commercial vehicle compound braking system and improve the braking feeling. [methods] according to the ECE regulations, the restrictions of motor, battery and braking sensation, etc. Combined with the characteristics of electric-pneumatic composite braking system of electric commercial vehicle, a series braking control strategy with the best sense is put forward. According to the braking intensity and I curve, the motor and pneumatic braking force are distributed. The braking control strategy model is established under the combined simulation environment of Cruise and Matlab. The performance of the series brake control strategy was verified by 60 km / h initial velocity primary braking condition and NEDC cycle condition. [results] the braking energy recovery rate of 19.43% and 19.43% was obtained at the same time when the optimal braking sensation was obtained at the same time. Under the condition of 17.39% NEDC, the energy recovery rate reached 18.56. [conclusion] the series braking control strategy of electric commercial vehicle can greatly improve the braking energy recovery rate under the premise of ensuring the best braking sensation. It is an effective method to improve braking performance and economy of electric vehicle.
