Problems solved by technology

However, since the existing E-Booster directly pushes the oil pressure of the master cylinder into the wheel cylinders of the four wheels, and the E-Booster itself does not have a valve body and cannot achieve anti-lock braking, for automatic driving with L3 and above driving levels For automobiles, if the ABS is ineffective, braking through the E-Booster active pressure building method is prone to the risk of wheel lock-up

Abstract

The invention provides a braking control method, system and device based on intelligent assisting and a storing medium. The method includes the following steps that a brake signal is received; the vehicle speed of an electric automobile and wheel speed data of rear wheels are acquired; according to the wheel speed data of the rear wheels and the corresponding relationship between the wheel speed and the braking torque of a wheel cylinder, a control target value of the braking torque of the wheel cylinder is calculated; according to the control target value, the rear axle braking force is acquired; according to the vehicle speed and the rear axle braking force, the front axle braking force is acquired; and according to the acquired rear axle braking force and the front axle braking force, an electric assisting system is controlled, so that the electric assisting system drives a hydraulic braking system. According to the braking control method, in the braking process, due to electronic braking force allocation, front and rear axles both have braking pressure, the braking efficiency is improved while the rear wheel anti-lock function is achieved, and therefore the driving safety is improved.

Description

technical field [0001] The present invention relates to the field of vehicle batteries, in particular to a braking control method, system, device and storage medium based on intelligent power assist. Background technique [0002] The vehicle braking system plays a vital role in vehicle safety. The most primitive braking control is just that the driver manipulates a group of simple mechanical devices to apply force to the brakes. At this time, the vehicle mass is relatively small and the speed is relatively low, and the mechanical brakes have met the needs of vehicle braking. With the increase of the self-quality of the car, the booster device has become very necessary for the mechanical brake. The first to appear was the vacuum booster. With the development of science and technology and the development of the automobile industry, new breakthroughs have been made in vehicle braking, and hydraulic braking is another major innovation after mechanical braking. [0003] The an...
