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. The control method is used for controlling the driving system to improve the stability of the speed of the electric vehicle after the off-road cruise function of the electric vehicle is started. Comprising the steps that at the first moment, the opening degree of an accelerator pedal of the electric vehicle is smaller than the preset accelerator pedal opening degree, the opening degree of a brake pedal is smaller than the preset brake pedal opening degree, and a driving motor of the electric vehicle is controlled to output torque so that the electric vehicle can run at the preset speed; at a second moment after the first moment, the road surface load of the road surface in contact with any wheel of the electric vehicle changes relative to the road surface load of the road surface in contact with the wheels at the first moment, and the driving motor is actively controlled to adjust torque output. Therefore, the torque output of the driving motor is controlled to stabilize the vehicle speed near the preset vehicle speed in response to the road load change in time, the stability of the vehicle speed in off-road cruise is improved, and the driving experience is improved.
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越野巡航功能启动之后控制驱动系统以提高电动车辆车速的稳定性。包括:在第一时刻,电动车辆的加速踏板的开度小于预设加速踏板开度且制动踏板的开度小于预设制动踏板开度,控制电动车辆的驱动电机输出扭矩以使电动车辆以预设车速行驶;在第一时刻之后的第二时刻,电动车辆的任一个车轮接触的路面的路面负载相对在第一时刻车轮接触的路面的路面负载变化,主动控制驱动电机调整扭矩输出。如此,实现了对路面负载变化及时响应控制驱动电机的扭矩输出以稳定车速在预设车速附近,提高了越野巡航中车速的稳定性,提高了驾乘体验。
