Problems solved by technology

like figure 1 As shown, when the driver brakes and decelerates again, especially when an emergency brake is required in an emergency, the air gap will consume a certain amount of driver's pedal stroke to make the friction plate contact the brake disc to produce a braking effect , this air gap will affect the response time of the braking force, sacrifice a certain deceleration effect, and cause the braking distance to become longer

Abstract

The invention discloses a brake clearance pre-filling control method, equipment, a storage medium and a device. The method comprises the steps that the current working state of a target vehicle is obtained; it is judged whether the current working state meets a brake clearance pre-filling triggering condition or not; and when the current working state meets the brake clearance pre-filling triggering condition, the brake system is pre-filled with brake pressure. When the current working state meets the brake clearance pre-filling triggering condition, the brake system is pre-filled with the brake pressure so as to reduce the air clearance between the brake disc and the brake friction plate, then if the brake pedal is treaded down again, the effective brake pressure can be generated immediately, and therefore, the braking response time and the time for achieving the target deceleration are shortened, when a driver conducts emergency braking, the air gap between the brake disc and the friction plate can be actively eliminated, the braking response time is shortened, and the purpose of improving the driving safety is achieved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a brake gap prefill control method, equipment, storage medium and device. Background technique [0002] With the development of social economy, automobiles have become an inseparable partner of human beings. The safety and reliability of automobiles have always been the focus of people's attention. Because of this, the research on the active safety performance of automobiles and the application of new technologies are happening with each passing day. Variety. [0003] The braking system is an important guarantee for the safe driving of the car. It can make the driving car slow down and stop within a short distance and maintain the stability of the driving direction. The quality of the braking performance is directly related to traffic safety and personal and property safety. Major traffic accidents It is often related to the situation that the braking distance of the c...
