Abstract
The embodiment of the application provides a kind of method, device and processor for determining the maximum torque of electric sanitation vehicle.The method comprises the following steps: collecting the actual speed of motor in real time;Determine the peak torque and rated torque according to the actual speed of motor;Select any one time as target time, and the previous time of target time as first time;Determine the maximum torque of electric sanitation vehicle at first time;According to the actual speed of motor at first time, determine the attenuation duration of motor speed from first time to target time;Control the torque of electric sanitation vehicle attenuates from the maximum torque of first time to the rated torque corresponding to target time within attenuation duration;The rated torque corresponding to target time is determined as the maximum torque of electric sanitation vehicle at target time.Using the above technical solution, the attenuation torque of electric sanitation vehicle can be controlled within the attenuation duration, which avoids the power shortage of vehicle caused by sudden attenuation of torque, and provides a good driving experience for the driver.
