一种可配置的车载高精定位软件方案研究

Research on a Configurable High-precision Positioning Software Solution for Vehicles

随着ADAS技术的普及和发展,车辆定位技术的作用也变得更加关键。只有保证车辆定位的精度才能确保许多ADAS应用场景的准确性。车载高精定位系统一般由定位芯片、SOC端、MCU端及RTK服务组成,其中定位芯片能结合GNSS技术与RTK数据从而进入高精定位模式。由于定位芯片和RTK服务都有多种主流产品导致车载高精定位系统存在大量的组合方案,相关的软件适配工作也因此变得非常繁重。文章提出一种可配置的车载高精定位软件方案,能通过修改软件配置文件便捷地适配多种定位芯片与RTK服务的组合方案,从而大幅提升软件的调试效率和可拓展性。

With the development and popularization of ADAS(Advanced Driving Assistance System),the vehicle positioning technology becomes more critical.Automotive high-precision positioning system includes positioning chip,SOC(System on Chip),MCU(Microcontroller Unit)and RTK(Real Time Kinematics)service,where positioning chip can achieve high-precision positioning by combining GNSS(Global Navigation Satellite Systems)with RTK technology Since there are various main products for positioning chips and RTK service,automotive high-precision positioning system has lots of schemes,which requires abundant hard work for software adaption.This paper suggests a configurable highprecision positioning software solution for vehicles,which is able to adapt the high-precision positioning software for different combinations of position chips and RTK service by simply modifying the configure file.Hence,the software debug efficiency and extensibility can be improved significantly.
