Problems solved by technology

[0002] Under the current technical conditions, among the endless ADAS functions, there are relatively few researches on assisting systems for lane-changing behavior. Currently, only one lane-changing assist system (LCA) is available on the market
In addition, in the existing research on related systems, there are not many studies on lane-changing driving behavior, and most of them focus on atypical lane-changing scenarios such as dangerous scenes and accident scenes. There are relatively few analyzes on typical lane-changing scenarios. The technical solution dedicated to the problem of lane change duration is blank

Abstract

The invention provides a highway lane change scoring model establishming method based on lane change duration, which comprises the steps of collecting historical data of the lane change duration, andformulating an abnormal value judgment rule; establishing a Logistic regression lane change duration time model; optimizing and eliminating independent variables with low dependent variable influencedegree; and according to the determined lane change duration model, establishing a score card for reminding a driver to pay attention to the potential lane change risk. The highway lane change scoringmodel establishing method based on lane change duration selects an independent variable which has a relatively large influence on the lane changing duration, establishes a lane change duration scoring model, evaluates the lane changing behavior of the driver in a scoring mode, monitors the behavior of the driver in real time in the automobile lane changing process, gives an alarm about the behavior exceeding the safe lane change duration time, and can also form the historical information of the lane change behavior of the driver to serve as the reference basis for traffic managers to formulate relevant policies and regulations.

Description

technical field [0001] The invention belongs to the field of intelligent networked vehicles, and in particular relates to a method for establishing an expressway lane change scoring model based on the lane change duration. Background technique [0002] Under the current technical conditions, among the endless ADAS functions, there are relatively few researches on assisting systems for lane-changing behavior, and only one lane-changing assist system (LCA) is currently on the market. In addition, in the existing research on related systems, there are not many studies on lane-changing driving behavior, and most of them focus on atypical lane-changing scenarios such as dangerous scenes and accident scenes. There are relatively few analyzes on typical lane-changing scenarios. The technical solution for specifically studying the problem of lane change duration is blank. However, the lane change duration is a very critical variable in the lane change behavior model. The probabilit...
