Title:
BEIDOU SPACE-TIME DATUM-BASED TYPE II AEBS TEST AND EVALUATION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2022/095617
Kind Code:
A1
Abstract:
A Beidou space-time datum-based type II AEBS test and evaluation device, comprising three parts, i.e., a roadside terminal information acquisition module, a vehicle-mounted terminal information acquisition module, and a comprehensive information processing module. The roadside terminal information acquisition module can obtain an accurate message sending time by means of a Beidou time service unit; the vehicle-mounted terminal information acquisition module can obtain an accurate time when a message from a roadside terminal is received, information acquired by an integrated inertial navigation unit, audio/vibration information acquired by a single chip microcomputer embedded unit and the like; the comprehensive information processing module can implement accurate and quantitative test and evaluation for indexes such as vehicle-to-roadside communication delay and an early warning signal sending time point. In the device, the globally unified Beidou space-time datum is used, and data analysis and processing are performed by using the SVM-based dynamic Hermite interpolation method, such that the test and evaluation result is accurate, there is no requirement for the communication mode of type II AEBS, it is convenient to test, and the application range is wide. Also provided is a Beidou space-time datum-based type II AEBS test and evaluation method.
