Automobile anti-lock braking control method and device realized based on neural network algorithm, vehicle and storage medium

Abstract

The invention provides an automobile anti-lock braking control method achieved based on a neural network algorithm. The method comprises the following steps that automobile observation data in the automobile braking / braking process are obtained; the preprocessed observation data are inputted into a neural network algorithm model to obtain a brake pressure value; and according to the brake pressure value, anti-lock brake control is conducted on the vehicle. According to the method, the anti-lock braking strategy is automatically learned from the automobile braking data by using the neural network, the design time of a manual coding anti-lock braking / braking system can be obviously shortened, and the automatic learning mode can be considered more comprehensively compared with manual coding, the learned anti-lock braking strategy can achieve an effect better than that of manual coding; in addition, the control quantity outputted by the algorithm is a brake pressure target value, and compared with a snub control mode of a traditional anti-lock braking system, control accuracy can be improved, and better control is achieved.

Description

technical field [0001] The invention belongs to the field of automobile control, and in particular relates to an automobile anti-lock braking control method, device, vehicle and storage medium based on a neural network algorithm. Background technique [0002] With the development of society, automobiles have been integrated into all aspects of people's daily life, providing great convenience for human production and life. Wet and slippery roads such as waterlogged roads and icy and snowy roads are very common on roads where cars are driving. When a car brakes suddenly on such roads, it is prone to sideslip, and in some extreme cases, violent deflection will occur. When the braking / braking force given by the braking system is too large, the wheels will be locked, causing the driver to lose control of the direction of the car. At this time, it is possible to drive out of the lane or into the reverse lane, and the ability to avoid obstacles will be greatly reduced. When the w...

Problems solved by technology

[0008] The traditional anti-lock braking system usually realizes the function by collecting the braking data of the real vehicle and manually coding and designing the braking rules, which requires a lot of manpower and material resources to realize the function, and does not have the ability of self-learning

The products of today's mainstream anti-lock braking system companies are accumulated and designed year after year. Quickly apply to new models

[0009] The traditional anti-lock braking system brakes through the "point brake" mode of "brake-release-brake-release..." cycle, which controls the current braking and the length of time for releasing the brake. However, the actual braking force acting on the wheels is determined by the braking pressure on the wheel cylinder, and the braking pressure is controlled through time in disguise. One consequence of this operation is that the actual wheel cylinder pressure control accuracy is not high, resulting in the actual braking process. tire lockup
