Problems solved by technology

Therefore, the driver of the target networked vehicle cannot receive the information of the networked vehicle within the communicable range at the same time. Due to the lag of human response, the transmission of information will be delayed, which will have a great impact on the stability of traffic.

Abstract

The invention relates to a network-connected vehicle following behavior prediction method under mixed traffic flow, and belongs to the field of intelligent driving. The following state of a target network connection vehicle is determined by considering the direct influence of the driving state of a leading vehicle on the target network connection vehicle and the direct influence of the driving state of the network connection vehicle in a communication range on the target network connection vehicle, and the driving state comprises the speed, the position and the acceleration. By using the prediction method, in the mixed traffic flow environment, a driver can not only directly sense the driving state of a preceding vehicle, but also sense the driving information of a connected vehicle in a communication range beyond the visual range, so that a more suitable driving decision can be made, and the traffic stability and the safety, the energy efficiency and the comfort of a target connectedvehicle are improved.

Description

technical field [0001] The invention belongs to the field of intelligent driving and relates to a method for predicting car-following behavior of networked vehicles under mixed traffic flow. Background technique [0002] Internet connection technology can provide all-round perception and better serve intelligent driving. In recent years, it has become a new direction for the development of intelligent transportation. Many world powers have stepped up research, deployment and implementation of network connection technology. For example, the United States plans to install V2V communication devices on all new cars from 2021. China is also intensively researching and developing LTE-V2X, a vehicle-to-vehicle communication technology, and it is expected that by 2020, the construction of Intelligent Road Traffic System (ITS) will make positive progress, and the coverage rate of vehicle wireless communication network (LTE-V2X) in large cities and expressways will reach 90%. %.
