Engine braking control method and device, computer equipment and readable storage medium

The invention relates to an engine braking control method and device, computer equipment, a computer readable storage medium and a computer program product, the engine speed, the vehicle speed and the current slope where a vehicle is located are obtained, the vehicle negative torque is calculated according to the vehicle speed and the current slope, and the engine braking power corresponding to the vehicle negative torque is determined; the engine is controlled according to the braking power of the engine, so that the rotating speed of the engine is within the preset deviation range, fine adjustment of the rotating speed of the engine is effectively achieved by accurately controlling the braking power of the engine, and therefore the safety and stability of the vehicle are improved under various driving environments; the power requirements of the engine are different, and reliable performance support can be provided in a complex driving environment, so that the control precision of the engine braking process
