The invention discloses a vehicle crawling working condition control method, device and equipment and a storage medium, and relates to the technical field of vehicle control. The method comprises the steps that motor rotating speed data are obtained, filtering and weighting processing is carried out on the motor rotating speed data in combination with the motor rotating speed in the adjacent time period so as to determine the target rotating speed of the motor, and then a series of known quantities such as the transmission speed ratio, the wheel radius and the vehicle kinetic equation are used for solving and obtaining the driving demand torque. According to the method, the limiting interval and the change threshold value of the torque are dynamically determined according to the current road section, the driving demand torque is necessarily adjusted so as to adapt to the uphill or downhill driving condition, and finally, the vehicle is accurately controlled according to the adjusted torque so as to meet the driving demand under the crawling working condition. According to the process, energy loss under the wriggling working condition is reduced, the energy use efficiency of the vehicle is improved, the driving experience is improved through accurate and high-adaptability torque control, and the driving process is more stable and natural.
