The invention provides a control method of an electric vehicle, a motor controller and the electric vehicle, and is applied to the technical field of electric vehicles, and the control method is used for controlling a driving system of the electric vehicle after a racing track mode of the electric vehicle is started so as to improve the driving controllability of the electric vehicle in a racing track. Comprising the steps that at a first moment, the opening degree of an accelerator pedal of the electric vehicle is a first accelerator pedal opening degree, the slip rate of the electric vehicle is smaller than a preset slip rate, and a driving motor is controlled to output a first torque indicated by the first accelerator pedal opening degree; at the second moment after the first moment, the opening degree of an accelerator pedal of the electric vehicle is the first accelerator pedal opening degree, the slip rate of the electric vehicle is larger than or equal to the preset slip rate, and the torque output by the driving motor is actively controlled to be reduced to be smaller than the first torque. Therefore, the torque output of the driving motor is controlled by responding to the slip rate change of the vehicle in time, the operation stability of the electric vehicle is improved, and the driving safety is ensured.
本申请提供了一种电动车辆的控制方法、电机控制器和电动车辆,应用于电动汽车技术领域,控制方法用于在电动车辆的赛道模式启动之后控制电动车辆的驱动系统以提高电动车辆在赛道中行驶的可操控性。包括:在第一时刻,电动车辆的加速踏板的开度为第一加速踏板开度且电动车辆的滑转率小于预设滑转率,控制驱动电机输出第一加速踏板开度所指示的第一扭矩;在第一时刻之后的第二时刻,电动车辆的加速踏板的开度为第一加速踏板开度且电动车辆的滑转率大于或等于预设滑转率,主动控制驱动电机输出的扭矩减小至小于第一扭矩。如此,实现了及时响应车辆的滑转率变化控制驱动电机的扭矩输出,提高了电动车辆的操稳性,保证了行车安全。
