Abstract

The invention provides a lane changing time model establishing method for natural driving vehicles on an expressway. The method comprises the steps that a main vehicle lane changing time model is established according to specific conditions of a main vehicle and a vehicle in front of the lane, historical data are brought into the main vehicle lane changing time model for simulation and regressionanalysis, parameter variables not high in influence on dependent variables are removed, and the main vehicle lane changing time model is optimized. According to the lane changing time model establishing method for the natural driving vehicle on the expressway, on one hand, the influence degree and direction of different factors on the lane changing behavior of a driver can be judged; on the otherhand, on the basis of mastering the behaviors of a driver and surrounding environment information elements, the lane changing intention, state and result of the driver can be analyzed, estimated and judged so as to warn and reduce bad driving lane changing behaviors.

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 natural driving vehicles on expressways. 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 vehicle Factors and so on, especially in China, the driving environment is complex and changeable, and the behavior of changing lanes at will is prominent. The research of the lane change model based on the actual driving conditions in our country is not only critical for the prevention and management of bad lane change driving behaviors, but also for the development of advanced driver assistance systems (ADAS) that meet the requir...
