The embodiment of the invention provides a method and device for determining the maximum torque of an electric sanitation vehicle and a processor. The method includes: acquiring actual rotating speed of a motor in real time; determining peak torque and rated torque according to the actual rotating speed of the motor; any moment is selected as a target moment, and a previous moment of the target moment is taken as a first moment; the maximum torque of the electric sanitation vehicle at the first moment is determined; determining attenuation duration of the rotating speed of the motor from the first moment to the target moment according to the actual rotating speed of the motor at the first moment; the torque of the electric sanitation vehicle is controlled to be attenuated from the maximum torque of the first moment to the rated torque corresponding to the target moment within the attenuation duration; and determining the rated torque corresponding to the target moment as the maximum torque of the electric sanitation vehicle at the target moment. By the adoption of the technical scheme, the torque of the electric sanitation vehicle can be controlled to be attenuated within the attenuation duration, insufficient vehicle power caused by sudden attenuation of the torque is avoided, and good driving experience is provided for a driver.

    本申请实施例提供一种用于确定电动环卫车的最大扭矩的方法、装置及处理器。包括:实时采集电机的实际转速;根据电机的实际转速确定峰值扭矩和额定扭矩;选定任意一个时刻作为目标时刻,将目标时刻的上一个时刻作为第一时刻;确定电动环卫车在第一时刻的最大扭矩;根据电机在第一时刻的实际转速确定电机转速从第一时刻至目标时刻之间的衰减时长;控制电动环卫车的扭矩在衰减时长内从第一时刻的最大扭矩衰减至与目标时刻对应的额定扭矩;将目标时刻对应的额定扭矩确定为电动环卫车在目标时刻的最大扭矩。采用上述技术方案,能够控制电动环卫车在衰减时长内将衰减扭矩,避免了扭矩突然衰减造成的车辆动力不足,且为驾驶人员提供了良好的驾驶体验。
