The invention discloses an electric vehicle climbing control method, a computer device and a storage medium, and the method comprises the steps: obtaining speed information and first driving force information before a vehicle arrives at a target ramp, and predicted gradient information and motor state information of the target ramp, and determining target driving force information according to the speed information and the predicted gradient information, and generating power control information according to the motor state information, the first driving force information and the target driving force information. According to the invention, the motor can be prevented from falling into dangerous states such as stalling in a reverse walking state, so that the motor can keep stable parameters such as rotating speed and back electromotive force in a non-reverse walking state, the climbing working condition of the electric vehicle is optimized, the power output of the motor in the electric vehicle can adapt to the change of a load, and the reliability of the electric vehicle is improved. The consequences of thermal protection triggering, cruising ability reduction, motor damage, automobile slope sliding and the like caused by over-temperature of the motor can be avoided, and driving safety and driving experience are guaranteed. The invention is widely applied to the technical field of automobiles.
