The invention provides a control method for virtual gear shift feeling generation of an electric vehicle. The control method includes generating and realizing a virtual sensation of gear shifting the same as that of a vehicle equipped with a multi-speed transmission, in the electric vehicle without a multi-speed transmission. In particular, virtual gear shift intervention torque and limit torque for each virtual gear shift stage are determined from input variables through a virtual gear shift model by inputting vehicle driving information collected from a vehicle during operation. Then the determined virtual shift intervention torque, the determined limit torque for each virtual shift stage, and motor torque command are applied to operate a motor, thereby realizing the virtual sensation of multi-speed gear shifting.

    本发明提供了一种电动车辆的用于生成虚拟换挡感觉的控制方法。所述控制方法包括在没有多挡位变速器的电动车辆中生成和实现与配备有多挡位变速器的车辆相同的虚拟换挡感觉。特别地,通过输入在操作期间从车辆收集的车辆驾驶信息,通过虚拟换挡模型从输入变量确定每个虚拟挡位的虚拟换挡干预扭矩和极限扭矩。然后,应用确定的虚拟换挡干预扭矩、每个虚拟挡位的确定的极限扭矩和电机扭矩指令以使电机运转,从而实现虚拟的多挡位换挡感觉。
