Vehicle brake control method, device, device and storage medium

Abstract

The invention discloses a vehicle braking control method, device, equipment and storage medium. The method includes: obtaining the current vehicle speed of the host vehicle, and detecting the braking signal of the host vehicle; if no braking signal is detected, determining the relative speed, the relative distance and the slippage of the host vehicle between the host vehicle and the anti-collision detection object. If it is determined that the current vehicle speed is higher than the set low speed threshold and the relative vehicle speed is greater than zero, then compare whether the relative distance is less than the set braking critical distance; if the relative distance is less than the set braking critical distance, then compare the slip rate Whether it is outside the set safe slip rate range; if the slip rate is outside the set safe slip rate range, start the coordinated control of the automatic emergency braking system and the anti-lock braking system to determine the coordinated control of the host vehicle. The power performs braking control on the host vehicle. Coordinated control of the working states of the automatic emergency braking system and the anti-lock braking system is realized through the comparison of multi-layer parameters, and control conflicts are avoided.

Description

technical field [0001] The present invention relates to the field of vehicle control, in particular to a vehicle braking control method, device, equipment and storage medium. Background technique [0002] Autonomous Emergency Braking (AEB) and Antilock Brake System (ABS) are two important components of automotive active safety. The ABS system can keep the slip rate of the vehicle near the optimum slip rate by controlling the wheel cylinder pressure of the wheel, effectively avoiding the wheel lock and sideslip phenomenon caused by the emergency braking of the car during driving. The AEB system can obtain information such as the relative speed and relative distance between the host vehicle and the target object in its driving direction in real time, and according to the obtained information and the system's built-in anti-collision safety distance (also known as the set braking critical distance) during the driving process of the host vehicle ) to calculate the risk of collis...

Problems solved by technology

In this way, there will be a conflict between the two systems, which may eventually lead to a decrease in the braking performance of the vehicle and a decrease in the handling stability of the vehicle.
