Abstract

The invention discloses a vehicle and its braking method and braking system. The method comprises the following steps: acquiring the distance between the vehicle and the obstacle in front during the running of the vehicle; acquiring the driving parameters of the vehicle, and according to The vehicle driving parameters determine the braking distance of the vehicle; calculate the distance difference between the vehicle distance and the braking distance, and judge whether the distance difference is greater than the preset first threshold; if the distance difference is not greater than the preset first threshold, then determine the The braking object and braking parameters corresponding to the difference; the braking object is controlled according to the braking parameters to realize the braking of the vehicle. The braking method of the present invention can evaluate the danger level in driving according to multiple signal parameters, and adopt different control strategies according to different danger levels, so as to ensure driving safety more accurately and avoid unnecessary losses and injuries.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle braking method, a vehicle braking system and a vehicle. Background technique [0002] At present, the service braking is to apply a braking force to the brake pads through the brake booster system, so that it rubs against the brake disc to brake. In the case of emergency braking, if the braking distance is not enough, accidents such as rear-end collisions often occur, resulting in loss of life and property. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, the first purpose of the present invention is to propose a vehicle braking method, which can evaluate the danger level in driving according to multiple signal parameters, and adopt different control strategies according to different danger levels, so as to ensure more accurate driving. Be safe a...
