Embodiment Construction

[0083] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0084] With the continuous increase of my country's traffic mileage and the explosive growth of car ownership, the development of transportation is facing the dual pressure of providing equal public services with wider coverage and ensuring road traffic safety and efficiency. In this context, the Advanced Driving Assistance System (Advanced Driving Assistance System, ADAS) for the purpose of improving traffic safety and vehicle intelligence has become the focus of research at home and abroad.

[0085]As an important part of ADAS, the adaptive cruise control system (Adaptive Cruise Control, ACC) realizes the auxiliary functions of cruise control and car following control, which can effectively reduce the burden on the driver, provide auxiliary support for the driver, and ensure driving safety at the same time. . In order to en...

Abstract

The invention discloses a performance evaluation method for a self-adaptive cruise control system. Firstly, for a high-grade road, a self-adaptive cruise control system performance test scene based onfront vehicle speed time varying is established; secondly, for comprehensively and accurately obtaining vehicle motion parameters in the testing process, the testing method is improved on the aspectof the methodology, and motion state parameters such as the position and the speed of a vehicle are accurately estimated through an improved self-adaptive Kalman filtering algorithm; and finally, based on the accurate recursive vehicle motion state parameters, multi-dimensional self-adaptive cruise control system performance evaluation indexes are proposed and quantified, and the self-adaptive cruise control system performance evaluation index system is constructed. According to the evaluation method provided by the invention, the defects that the test scene does not accord with the reality,the evaluation index is relatively single and the like in an existing method are overcome, and high-precision, reliable and comprehensive scientific quantitative evaluation of the performance of the self-adaptive cruise control system in a complex scene is realized.

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 method for evaluating the performance of an adaptive cruise control system. Background technique [0002] With the continuous increase of my country's traffic mileage and the explosive growth of car ownership, the development of transportation is facing the dual pressure of providing equal public services with wider coverage and ensuring road traffic safety and efficiency. In this context, the Advanced Driving Assistance System (Advanced Driving Assistance System, ADAS) for the purpose of improving traffic safety and vehicle intelligence has become the focus of research at home and abroad. [0003] As an important part of ADAS, the adaptive cruise control system (Adaptive Cruise Control, ACC) realizes the auxiliary functions of cruise control and car following control, which can effectively reduce the burden on the dr...
