Intelligent Driving BDS High-Precision Navigation System Performance Requirements and Verification

At present, most Chinese automated vehicles companies are inclined to use BDS/GNSS and INS high-precision combined positioning receivers as main solution to achieve high-precision position perception of automated vehicles. But, there’re not unified performance requirements for the BDS/GNSS high-precision navigation system (HNS) of intelligent driving currently. It’s difficult to evaluate overall performance of this system based on a generally accepted principle. Research presented in this paper is to solve the problem of inconsistent, uncoordinated, and non-standard overall performance metrics, and promote development of the BDS/GNSS high-precision navigation system. Based on actual needs of L3–L4 automated vehicles, and more than 200,000 km data collected from the large-scale operation of SAIC MOTOR container truck, this paper puts forward to performance requirements of the BDS/GNSS high-precision navigation system such as accuracy, availability, continuity and integrity for automated vehicles in park scenes and high-speed scenes. And rationality of those performance requirements is verified via three test routes data.
