The invention discloses an automobile power control method and device based on road surface optimal slip rate recognition, and the method comprises the steps: S1, an optimal slip rate range of a current driving road is obtained in a vehicle driving process; and S2, vehicle braking and driving are controlled; specifically, in the vehicle braking process, pressurization-pressure maintaining-pressure reducing-pressurization circulation is conducted with the optimal slip rate as the target, and the slip rate of each tire is within the optimal slip rate range in the braking process; in the vehicle driving process, the slip rate of the driving wheel is monitored in real time, when the slip rate of the driving wheel exceeds the target optimal slip rate, a torque reduction instruction is sent to a corresponding driving assembly in the driving system, and the slip rate of the driving wheel is within the optimal slip rate range. Driving and braking forces provided by the road surface can be quickly and fully utilized in the driving and braking process of the vehicle, the control efficiency of a power system of the whole vehicle is improved, the braking distance is shortened, the braking safety is improved, the driving efficiency is improved, and tire abrasion is reduced.
