The invention provides a predictive hybrid power control method and device, equipment and a medium. The method comprises the steps that according to a first difference value between the reference vehicle speed and the actual vehicle speed of a vehicle, the reference longitudinal acceleration of the vehicle is obtained through a PID controller of the vehicle, and the wheel end required torque of the vehicle is obtained according to a longitudinal dynamic model corresponding to the reference longitudinal acceleration; acquiring an equivalent fuel consumption parameter of the vehicle according to the fuel consumption rate of the vehicle and the equivalent fuel consumption rate of the battery; according to the battery dynamical model and the SOC dynamical model, obtaining a state transition constraint of the vehicle, and according to a constraint condition, obtaining a minimum value of an integral of the equivalent fuel consumption parameter; and according to the minimum value, the motor torque of the vehicle is obtained, and according to the wheel end demand torque and the motor torque, the engine torque of the vehicle is obtained. According to the method, the fuel economy can be improved.
