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 of an adaptive cruise control system. Firstly, for high-grade highways, a performance test scenario of the adaptive cruise control system based on the time-varying vehicle speed of the preceding vehicle is established. Secondly, in order to comprehensively and accurately obtain the vehicle motion parameters during the test process, the test method is improved at the methodology level, and the improved adaptive Kalman filter algorithm is used to accurately estimate the vehicle's position, speed and other motion state parameters. Finally, based on the accurate and recursive vehicle motion state parameters, a multi-dimensional adaptive cruise control system performance evaluation index is proposed and quantified, and an adaptive cruise control system performance evaluation index system is constructed. The evaluation method proposed by the present invention overcomes the shortcomings of the existing method that the test scene does not match the actual situation and the evaluation index is relatively single, and realizes high-precision, reliable and comprehensive scientific quantitative evaluation of the performance of the adaptive cruise control system in a complex scene.

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...
