摘要
探讨了动力电机、电池和传动系统传动比对电动汽车整车动力性的影响,以某款电动汽车动力性要求对动力总成进行匹配。利用AVLCruise搭建整车运动学模型并进行仿真。以续驶里程为目标对传动系统进行优化,优化结果提高了整车续驶里程,具有一定实际意义。
The influence of motor,battery and transmission gear ratio to electric vehicle dynamics is discussed.The powertrain of an electric vehicle is matched based on the power requirements.The kinematics model is built and emulated with AVL Cruise.Transmission gear ratio is optimized with the driving range as the objective function;the driving range is improved with the optimization result.The method has certain practical meaning.
