The invention provides an electric vehicle emergency driving control method and an electric vehicle, the electric vehicle comprises a control system, an emergency switch, a driver, a driving motor andan original encoder, and the method is applied to the control system and comprises the steps that obtaining emergency state switching information, wherein the emergency state switching information isgenerated when the electric vehicle is switched from a normal state to an emergency state by the emergency switch, and when the electric vehicle is in the normal state, the control system is in communication connection with the original encoder and driving control on the electric vehicle is realized based on an output signal of the original encoder; cutting off the communication connection between the control system and the original encoder according to the emergency state switching information; and obtaining a gear signal and an accelerator signal, generating a control instruction accordingto the gear signal and the accelerator signal, and sending the control instruction to the driver, so that the driver controls operation of the driving motor based on the control instruction. In this way, emergency operation can be achieved when the electric vehicle cannot operate, vehicle repair is facilitated, and manpower and material resources are saved.

    本申请提供一种电动汽车应急行车控制方法及电动汽车,电动汽车包括控制系统、应急开关、驱动器、驱动电机、原配编码器,方法应用于控制系统,包括:获取应急状态切换信息,其中,应急状态切换信息由应急开关将电动汽车从正常状态切换为应急状态时产生,电动汽车处于正常状态时,控制系统与原配编码器通信连接,并基于原配编码器的输出信号对电动汽车实现行车控制;根据应急状态切换信息,切断控制系统与原配编码器之间的通信连接;获取挡位信号和油门信号,根据挡位信号和油门信号,生成控制指令,并发送给驱动器,以使驱动器基于控制指令控制驱动电机的运转。这样可以在电动汽车无法运行时实现应急运行,便于车辆的送修,节约人力物力。
