Intelligent vehicle safety driving enveloping reconstruction method integrated with characteristic of space and dynamics

Abstract

The invention discloses an intelligent vehicle safety driving enveloping reconstruction method integrated with characteristic of space and dynamics. The intelligent vehicle safety driving enveloping reconstruction method integrated with characteristic of space and dynamics is characterized in that starting from the behavior of simulating a real driver to estimate the potential bumping risk in the forward driving area, introducing an estimation result of the forward vehicle driving behavior into an environment perception link of an intelligent vehicle; and based on the estimation result of the forward vehicle driving behavior, by means of integration of characteristic of space and dynamics, performing reconstruction (safety environment enveloping reconstruction and stable control enveloping reconstruction ) on safety driving enveloping of the intelligent vehicle to improve safety and stability of the intelligent vehicle. The intelligent vehicle safety driving enveloping reconstruction method integrated with characteristic of space and dynamics corrects the transverse spacing and the longitudinal spacing between the intelligent vehicle and the forward vehicle based on the estimation result of the forward vehicle driving behavior to realize safety environment enveloping reconstruction of the intelligent vehicle and improve the safety of the intelligent vehicle. Moreover, based on the reconstructed safety environment enveloping reconstruction, by a combination with an intelligent vehicle dynamical model, the intelligent vehicle safety driving enveloping reconstruction method integrated with characteristic of space and dynamics can perform reconstruction on stable control enveloping of the intelligent vehicle and can improve the stability of the intelligent vehicle.

Description

technical field [0001] The invention relates to the field of intelligent vehicles, in particular to a method for reconstructing a safe driving envelope of an intelligent vehicle that integrates spatial and dynamic characteristics. Background technique [0002] With the rapid development of the automobile industry and the continuous improvement of people's living standards, the number of automobiles has continued to rise, followed by a series of urgent problems such as increasing traffic pressure, road congestion, and frequent traffic accidents.
