摘　　要：基于纵向加速度、车速、电机扭矩等信号,通过纵向动力学公式估算整车质量,并将其作为输入参数计算能量回收回馈扭矩,使整车在不同载荷工况下具有相同的目标减速度。试验结果表明,在实际道路上测试时整车质量估算误差在±10%范围内,使用整车质量参数进行能量回收计算后,在CRUISE软件中基于中国重型商用车瞬态循环(C-WTVC)工况进行仿真时能耗优化5.5%。The vehicle mass,which was estimated from longitudinal dynamics formula based on longitudinal acceleration,vehicle speed,motor torque,was used as input parameter to calculate energy recovery feedback torque,to make the vehicle has the same target deceleration under different loads.Test results indicate that the accuracy of vehicle mass falls in the range of±10%in the real road test,and when vehicle mass is used to calculate energy recovery,the energy consumption is optimized by 5.5%in CRUISE simulation based on China-World Transient Vehicle Cycle(C-WTVC).
