[0034] S101 constructing a car-following fleet model;

[0035] Common merging behaviors in actual driving can be divided into two types. One is merging in low-density traffic flow, which can usually be simplified as the two-vehicle interaction between the main test vehicle and the interfering vehicle in the target lane; the other is high-density merging. The ...

Abstract

The invention belongs to the field of vehicle testing and relates to a method for realizing merging in high-density virtual traffic flow on the basis of a heuristic evaluation strategy. The method comprises the following steps that: a following motorcade model is constructed; an automatic driving control algorithm is applied to generate the following motorcade model on a side lane of a test vehicle, and the following motorcade model is injected into the test vehicle through an RSU for testing; the test vehicle sends a merging request to the following motorcade, detects and identifies time headway feedback in the following motorcade, and performs merging operation when a safe merging opportunity appears; and the merging operation is evaluated on a virtual simulation platform physical engine. Thus, after a merging test based on the heuristic evaluation strategy is carried out in the simulated high-density traffic flow, the motor vehicle has the capability of driving in the high-density traffic flow in a real driving environment to complete the merging operation.

Description

technical field [0001] The invention relates to the field of vehicle testing, in particular to a merging method based on a heuristic evaluation strategy in a high-density virtual traffic flow. Background technique [0002] At present, the merging test of connected cars is limited to low-density traffic flow. The test vehicle only needs to detect a few parallel vehicles in the surrounding area, and choose to accelerate to open a safe distance or decelerate to leave a safe distance before performing the merging operation. [0003] The merging behavior test of networked vehicles in low-density traffic flow has great limitations, and it cannot cover the merging behavior after forming high-density car-following traffic flow that is common in real driving scenarios. After the vehicle passes the simple parallel behavior test, it still cannot cope with real driving scenarios. Contents of the invention [0004] The purpose of the present invention is to provide a merging method ba...
