Problems solved by technology

[0003] However, the above-mentioned engine braking and retarder braking all require the user to manually open the brake during driving.
The way of manual opening is not only cumbersome, which affects the driving safety of users, but also in engine braking, if the timing of manual opening is wrong, or the level of engine braking is too low, the maximum efficiency of engine braking will not be activated. The engine braking level is too high and may cause engine overspeed
In retarder braking, because the user cannot accurately know the timing of its opening and closing, it may cause the retarder braking system to be used for too long, and the retarder braking system needs to be used for a long time Only when the oil temperature dissipates quickly can it maintain its braking performance

Abstract

The invention provides a control method and device for auxiliary braking of a vehicle, a storage medium and electronic equipment, and relates to the technical field of auxiliary braking of the vehicle, the vehicle comprises an auxiliary braking system, and the method comprises the steps that current driving parameters of the vehicle are obtained; judging whether the vehicle is in a preset first driving condition according to the current driving parameters of the vehicle; and when the vehicle is in the preset first driving condition, an auxiliary braking system is started to adjust the vehicle to be in the preset second driving condition. According to the technical scheme, auxiliary braking can be automatically started at the preset appropriate time, and therefore the braking effect and driving safety of the vehicle are guaranteed.

Description

technical field [0001] The present invention relates to the technical field of vehicle auxiliary braking, and in particular, to a control method, device, storage medium and electronic device for auxiliary braking of a vehicle. Background technique [0002] In the automotive field, braking methods include service braking, parking braking, engine braking and retarder braking. Among them, the service brake generally refers to the use of the brake pedal for braking, and the service brake cannot be used for a long time. The long-term braking may cause the brake device to overheat and cause the thermal decline of the braking efficiency; the parking brake is generally not used. If you use the brakes while driving, it may cause accidents such as tail drift. Both engine braking and retarder braking belong to auxiliary braking. In engine braking, it is generally divided into engine exhaust braking and engine in-cylinder braking. The engine exhaust brake is closed by the throttle val...
