Abstract

The invention provides a braking control method, device and equipment and a storage medium. The method comprises the steps that when it is determined that an engine is in the braking working condition, the current rotation speed of the engine is acquired; whether the current rotation speed is higher than preset critical rotation speed or not is determined, wherein the critical rotation speed is the critical speed between a middle-low rotation speed area and a high rotation speed area, the rotation speed in the middle-low rotation speed area is the braking rotation speed commonly used by a user, and the rotation speed in the high rotation speed area is not lower than the maximum rotation speed in the middle-low rotation speed area; if not, the deflation opening degree of a supercharger is controlled to be zero; and if yes, the deflation opening degree of the supercharger is adjusted to a first opening degree value, wherein the first opening degree value is larger than a second opening degree value, the first opening degree value is the deflation opening degree corresponding to the current rotation speed when the engine is in the braking working condition, the second opening degree value is the deflation opening degree corresponding to the current rotation speed when the engine is in the positive work working condition, and the first opening degree value is larger than zero. According to the scheme, variable adjustment of the braking power can be achieved, and then the reliability of the engine is improved.

Description

technical field [0001] The present invention relates to the technical field of engines, in particular to a braking control method, device, equipment and storage medium. Background technique [0002] Supercharged engines are currently used in more and more vehicles. The working principle of an engine equipped with a supercharger is: the exhaust gas generated by the combustion of oil and air in the cylinder of the engine is output to the supercharger, and the supercharger is driven by the exhaust gas, so that the supercharger compresses the new air. And send the compressed air into the cylinder. Among them, the supercharger is provided with a bypass valve. By adjusting the opening of the bypass valve, that is, the opening of the supercharger, the exhaust gas output from the cylinder can be partially discharged, so as to adjust the intake of the cylinder. Gas volume, thereby adjusting the power of the engine. [0003] In the prior art, when the engine is in a positive power ...
