A control method, terminal equipment, and storage medium for an automatic brake assist system

Abstract

The present invention relates to a control method, terminal equipment and storage medium of an automatic brake assist system. The method includes: S1: collecting the running information of vehicles in front of and on the side of the vehicle, and judging the condition of the road where the vehicle is located. When the road is a straight road , enter S3, otherwise, enter S2; S2: determine whether the vehicle is in danger of collision, if so, send a warning signal, otherwise, end; S3: extract the vehicle that is most dangerous to the vehicle and mark it as a dangerous vehicle; S4: judge The dangerous vehicle is in the same road as the car or in the adjacent road, and it is judged whether the automatic braking assist system needs to be activated. When the automatic braking assist system is activated, enter S5; otherwise, end; S5: Calculate the safe braking distance and deceleration of the vehicle; S6: Calculate the relative collision time; S7: Control according to the relationship between the relative collision time and the three time thresholds. The present invention can implement tight braking to avoid collision accidents when the driver mishandles the possible collision situation.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to a control method for an automatic brake assist system, a terminal device and a storage medium. Background technique [0002] The conventional automatic brake assist system (AEB) operates based on the distance value measured by the sensor installed on the vehicle and the target vehicle of the control object. Therefore, the traditional AEB control method generally can only control one front vehicle directly ahead. [0003] However, when vehicles are running on the road, the working conditions are complex and changeable, such as T-shaped intersections, curves, merges, crossroads, etc. In most cases, there are more vehicles in these working conditions. If the drivers of these vehicles do not observe the intersection carefully, there may be blind spots on both sides, such as T-shaped intersections, and the use of traditional automatic brake assist systems for control may cause a ris...
