Problems solved by technology

[0003] In the related technology, the vehicle brake is controlled by setting the lateral deceleration to avoid collision with the vehicle in front. Although this technology can avoid collision with the vehicle in front or reduce the intensity of the collision, it does not consider the lateral movement state of the own vehicle when emergency braking is performed. Especially during emergency braking on bends, possible braking instability cannot be avoided

Abstract

The invention discloses a control method and system for emergency braking of an automobile and the automobile. The control method includes the steps that the front axle load, the rear axle load and the mass center height of the automobile are calculated according to the height of an automobile body; in the running process of the automobile, the current front axle cornering stiffness and the current rear axle cornering stiffness of the automobile are read; the current deceleration limit value for emergency braking of the automobile is calculated according to the mass center height, the front axle load, the rear axle load, the front axle cornering stiffness and the rear axle cornering stiffness; and emergency braking of the automobile is controlled according to the deceleration limit value. By means of the control method, collisions can be avoided or relieved, braking unstability is avoided, and the running safety is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a control method, system and vehicle for emergency braking of automobiles. Background technique [0002] The on-board active braking system uses millimeter-wave radar, lidar, camera and other sensors to detect the position and movement relationship between the vehicle in front and the own vehicle. When there is a collision risk, it will issue a warning and automatically apply the brakes when necessary to avoid danger or reduce collision damage. degree of purpose. [0003] In the related technology, the vehicle brake is controlled by setting the lateral deceleration to avoid collision with the vehicle in front. Although this technology can avoid collision with the vehicle in front or reduce the intensity of the collision, it does not consider the lateral movement state of the own vehicle when emergency braking is performed. Especially during emergency braking on a curve, poss...
