System and method for predicting driving state of surrounding vehicle based on driving intention

Abstract

The invention discloses a system and method for predicting the driving state of a surrounding vehicle based on driving intention. The system includes a feasible trajectory set generation module, a behavior intention generation module, and a predicted trajectory generation module; the feasible trajectory set generation module is used for determining a current drivable lane of a target vehicle to generate a feasible trajectory according to the result of global path planning; a behavior intention interference module is used for predicting the probability of the target vehicle choosing different lanes by analyzing the satisfaction of target vehicle with different lanes, traffic regulations, and the state of the vehicle; the predicted trajectory generation module is used for fusing to obtain apredicted trajectory based on the result of a generated feasible trajectory set and the probability of a corresponding trajectory. The problems of neglecting the interaction between the environment and a driver and dynamically changing of the environment when predicting the state of the vehicle in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of vehicle driving, and specifically refers to a system and method for predicting the motion state of surrounding vehicles based on driving intention. Background technique [0002] With the increasing number of cars, road traffic tends to be denser and more complicated, which leads to an increase in driving pressure, which reduces the driving ability of drivers in normal traffic scenarios and greatly increases the probability of traffic accidents. Among them, lane-changing behavior is one of the important causes of traffic accidents and traffic congestion, especially in urban areas, where the traffic density is high, and lane-changing collisions are prone to occur, even leading to serial rear-end collisions. The vast majority of lane-changing collision accidents are due to the inaccurate perception of the motion state and position information of the surrounding vehicles by the lane-changing vehicle and wrong...
