Problems solved by technology

[0003] Under the existing technical conditions, the research and development of related technologies is to study the lane change behavior in dangerous scenes such as emergency lane change conditions and forced lane changes at intersections, or corner scenes, but the research on the duration of lane change in general scenes is practical. is blank

Abstract

The invention provides a method for establishing a lane change time model for a natural driving vehicle on a highway, which includes establishing a lane change time model of the main vehicle according to the specific conditions of the main vehicle and the vehicle in front of the lane, and bringing historical data into the lane change time of the main vehicle. Simulation is carried out in the model and regression analysis is carried out, the parameter variables that have little influence on the dependent variable are eliminated, and the lane change time model of the main vehicle is optimized. The present invention is a method for establishing a lane-change time model for a natural driving vehicle on a highway. On the one hand, the influence degree and direction of different factors on the driver's lane-changing behavior can be judged; on the other hand, the driver's behavior and surrounding environment information elements can be mastered Based on the analysis, estimation and judgment of the driver's lane change intention, state and result, to warn and reduce the bad driving behavior.

Description

technical field [0001] The invention belongs to the field of intelligent networked vehicles, and in particular relates to a method for establishing a lane change time model for a natural driving vehicle on a highway. Background technique [0002] Vehicle lane changing is a frequent phenomenon in traffic scenes, and it is an important source of potential safety hazards and traffic accidents. The characteristics of lane changing behavior are very complex and are affected by different factors, including driver factors, environmental road factors and vehicles. Factors and so on, especially in China, the driving environment is complex and changeable, and the random lane change behavior is prominent. The development of a lane-changing model based on the actual driving situation in my country is not only critical for preventing and managing bad lane-changing driving behaviors, but also for developing advanced driver assistance systems (ADAS) that meet the requirements of my country...
