Vehicle brake control method, device, electronic equipment and medium based on aeb

Abstract

The present invention relates to an AEB-based vehicle braking control method, device, electronic equipment, and medium. The method includes: obtaining first section parameters and second section parameters of vehicle braking after AEB equipment intervenes; according to the AEB equipment The parameters of the first section and the second section of vehicle braking after intervention, setting a plurality of braking monitoring points in the second section, and obtaining the estimated acceleration of the vehicle when braking in the second section, and Estimated vehicle running speed at each braking monitoring point; control the vehicle to perform vehicle braking according to the estimated acceleration and the estimated vehicle running speed at each braking monitoring point. This application collects the vehicle braking parameters after AEB equipment intervention, obtains the estimated driving acceleration and speed when the vehicle is braking, and controls the vehicle to correct the driving speed and acceleration of each braking monitoring point to the estimated speed when the vehicle actually performs braking. The speed and acceleration of the vehicle are achieved, so as to achieve the goal of using AEB equipment to brake the vehicle at a constant speed and stably.

Description

technical field [0001] The present invention relates to the technical field of vehicle braking, in particular to an AEB-based vehicle braking control method, device, electronic equipment and computer storage medium. Background technique [0002] AEB (Autonomous Emergency Braking) is an active safety technology for automobiles. The AEB system uses radar to measure the distance to the vehicle in front or obstacles, and then uses the data analysis module to compare the measured distance with the warning distance and safety distance. For comparison, when the distance is less than the warning distance, the warning prompt will be issued, and when the distance is less than the safe distance, even if the driver does not have time to step on the brake pedal, the AEB system will activate, so that the car will brake automatically, thus escorting safe travel. [0003] In the prior art, after the AEB measures the distance of the vehicle in front or the obstacle, when the warning duration...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, after the AEB measures the distance of the vehicle in front or the obstacle, when the warning duration threshold is reached, the previous period is set as the warning period, and the latter period is set as the braking period. Consider correcting the vehicle’s actual braking speed and acceleration based on the vehicle’s predicted speed and acceleration, so that the AEB equipment’s control parameters for the vehicle’s braking effect on the vehicle’s braking are not obvious enough, and the AEB equipment’s control of the vehicle cannot achieve uniform speed stability braking effect
