Problems solved by technology

[0003] In general, although most of the current research results on CACC systems have been verified by simulation, due to the high cost, these conclusions are rarely verified in real life, and only visually observe driver behavior and traffic conditions. Flow characteristics cannot fully grasp the characteristics of traffic flow of CACC vehicles in different scenarios

Embodiment Construction

[0092] In order to make the purpose, technical solutions and advantages of the invention clearer, the technical solutions proposed in the present invention will be described more clearly and completely below with reference to the accompanying drawings and specific embodiments.

[0093] The invention completes the microscopic simulation of the CACC vehicle by establishing the microscopic model of the cooperative adaptive cruise control vehicle. Among them, the establishment of CACC micromodel, such as figure 1 It includes the following four steps:

[0094] Step 1: Determine the combinatorial logic of the CACC fleet

[0095] In this step, there are three types of vehicles in the traffic flow of cooperative adaptive cruise control, CACC pilot vehicle, CACC member vehicle and CACC free vehicle. The CACC pilot car is the first car in the fleet, leading the entire fleet. The CACC member car is a member of the team and follows the car in front. The CACC free vehicle refers to the...

A complete method is provided for microscopic simulation of the cooperative adaptive cruise control vehicle, application of the method in the future traffic field is considered, and a basis is provided for related research of the cooperative adaptive cruise control vehicle.

Description

technical field [0001] The invention relates to a microscopic simulation method of a cooperative adaptive cruise control vehicle, belonging to the field of microscopic traffic flow. Background technique [0002] With the continuous development of mobile internet technology and intelligent driving technology, a fleet of information-connected vehicles has been formed in the traffic flow. Cooperative Adaptive Cruise Control (CACC) technology is a specific application of intelligent networked vehicles. It can control the distance between vehicles by sharing speed, acceleration and other information between vehicles to ensure vehicle driving stability and driving. Safety. Based on these characteristics of CACC, many problems such as traffic congestion, traffic pollution, traffic accidents, and traffic demand expansion can be well solved. [0003] In general, although most of the current research results on CACC systems have been verified by simulation, due to its high cost, the...
