Control method and device for vehicle braking and vehicle having the same

Abstract

The invention discloses a vehicle braking control method and device and a vehicle with the vehicle braking control device. The method includes the steps that the current image and lane line information in front of a vehicle are acquired; the current distances between multiple obstacles and the vehicle are detected; and according to the current distances, the current position of each obstacle in the current image is confirmed, and when it is judged that a collision will happen in the current position and the corresponding current distance reaches a braking distance according to the lane line information, the vehicle is controlled to brake. By the adoption of the method, the relative position relation between each front obstacle and a lane in the direction of the vehicle can be accurately recognized, so that the vehicle accurately brakes according to the relative position relation, mistaken braking or omitted braking is avoided, the safety and reliability of the vehicle are improved, anduser experience is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a control method and device for vehicle braking and a vehicle with the same. Background technique [0002] In related technologies, many vehicles have an automatic emergency braking function. Specifically, the millimeter-wave radar sensor detects the surrounding environment of the vehicle, and evaluates the potential collision risk between the vehicle and the obstacle in front in real time. Once the collision risk reaches the level, it needs to be avoided by braking the vehicle When the accident occurs, the braking system of the vehicle will perform emergency braking to achieve the purpose of deceleration and collision avoidance. [0003] However, since the millimeter wave radar sensor judges whether there is an obstacle in front according to the echo information, it cannot judge the relative positional relationship between the obstacle in front and the lane in the direction ...

AI Technical Summary

Problems solved by technology

[0003] However, since the millimeter wave radar sensor judges whether there is an obstacle in front according to the echo information, it cannot judge the relative positional relationship between the obstacle in front and the lane in the direction of the vehicle, resulting in the inability to accurately identify the main obstacle when multiple targets are close in distance. , interferes with the judgment of the automatic emergency braking function, and there will be false braking or missing braking, which will reduce the safety and reliability of the vehicle, which needs to be solved urgently
