Embodiment Construction

[0122] With the continuous increase of the number of vehicles, the number of vehicles driving on the expressway increases, and each vehicle needs to maintain a safe inter-vehicle distance to ensure driving safety, which makes the expressway capacity easy to reach saturation and the improvement of traffic efficiency difficult. And that is to say, the platoon driving can shorten the distance between vehicles because the driving routes of the vehicles in the group are consistent, and the driving efficiency is effectively improved. At the same time, studies have shown that platoon driving can help reduce fuel consumption and reduce carbon dioxide emissions. In view of this, the research on platoon driving has received extensive attention at home and abroad. Among them, due to the particularity of large trucks (the main force of road transport and high fuel consumption), the research on platoon driving is more concentrated on the platoon driving of large trucks.

Abstract

The invention provides a method for testing and evaluating the driving performance of an intelligent vehicle queue. The method comprises the following steps: firstly, constructing a queue driving performance test scene of the intelligent vehicle by integrating the existing standard and the characteristics of large truck queue driving; secondly, utilizing an improved unscented Kalman filtering algorithm to accurately calculate key kinematics parameters of each vehicle in queue driving; and finally, quantizing and outputting performance indexes of intelligent vehicle queue driving, namely kilometer passing time, queue consistency and vehicle distance stability, so as to realize scientific and quantitative evaluation of intelligent vehicle queue driving.

Description

technical field [0001] The invention belongs to the technical field of road testing and testing of intelligent driving vehicles, and in particular relates to a test and evaluation method for the driving performance of intelligent vehicle platoons. Background technique [0002] With the continuous increase of the number of vehicles, the number of vehicles driving on the expressway increases, and each vehicle needs to maintain a safe inter-vehicle distance to ensure driving safety, which makes the expressway capacity easy to reach saturation and the improvement of traffic efficiency difficult. And that is to say, the platoon driving can shorten the distance between vehicles because the driving routes of the vehicles in the group are consistent, and the driving efficiency is effectively improved. At the same time, studies have shown that platoon driving can help reduce fuel consumption and reduce carbon dioxide emissions. In view of this, the research on platoon driving has re...
