Comprehensive cooling control method for new energy vehicle driving motor

The invention relates to a comprehensive cooling control method of a new energy vehicle driving motor. The control method comprises the following steps: firstly, introducing two parameters, namely anenvironment temperature Tamb and a vehicle speed Vhost, which have great influence on cooling of a driving motor M into control of a water cooling system; in combination with a specific algorithm, obtaining a target heat dissipating capacity Qaim needing auxiliary heat dissipation of a water cooling system, and further obtaining a target water inlet temperature Taim for cooling the driving motor M; calculating the rotating speed requirements of the water pump P and the fan F based on the temperature, and fusing the operation control logic to obtain the control duty ratios of the water pump P and the fan F; and finally, outputting pulse width modulation control PWM signals through a controller hard wire, and achieving starting, stopping and rotating speed control over the water pump P and the fan F.
