The embodiment of the invention provides a control method for an electric sanitation vehicle, a controller and the electric sanitation vehicle. The method comprises the steps that under the condition that the electric sanitation vehicle is controlled to enter an electric crawling working condition, the target rotating speed of a motor is determined according to the current gear and the target vehicle speed of the electric sanitation vehicle; determining a vehicle speed interval corresponding to the electric sanitation vehicle at the current gear, and a torque limit value interval and a torque change rate interval corresponding to the vehicle speed interval; determining a first limit value of the torque of the motor and a second limit value of the torque change rate according to the current vehicle speed, the vehicle speed interval, the torque limit value interval and the torque change rate interval of the electric sanitation vehicle; and the target rotating speed, the first limiting value and the second limiting value are sent to a motor controller, so that the motor controller controls a motor to enter a motor rotating speed mode, the rotating speed of the motor is adjusted to the target rotating speed, the current vehicle speed reaches the target vehicle speed, the response speed of rotating speed control is increased, and the electric sanitation vehicle runs stably.

    本申请实施例提供一种用于电动环卫车辆的控制方法、控制器及电动环卫车辆。方法包括:在控制电动环卫车辆进入电蠕行工况的情况下,根据电动环卫车辆的当前档位和目标车速确定电机的目标转速;确定电动环卫车辆在当前档位下所对应的车速区间,以及车速区间所对应的转矩限制值区间和转矩变化率区间;根据电动环卫车的当前车速、车速区间、转矩限制值区间以及转矩变化率区间确定电机的转矩的第一限制值和转矩变化率的第二限制值;将目标转速、第一限制值以及第二限制值发送至电机控制器,以使电机控制器控制电机进入电机转速模式,并将电机的转速调整至目标转速,以使当前车速达到目标车速,以提高转速控制的响应速度,使电动环卫车辆平稳运行。
