随着城市建设的发展,密集的建筑物、深长的隧道等使车辆在行驶中仅仅依靠GPS无法实现全面定位,而车辆定位是车联网的关键技术之一,也正是实现车联网要急需解决的难点。就GPS盲区对车辆定位进行研究,首先介绍车联网的架构,车路协同定位原理及定位难点;然后采用速度-方向盘转角传感器(VSSA,Vehicle Speed&Steering Angle)定位的方法建立GPS盲区车辆定位的计算模型;最后通过仿真验证VSSA定位方法的准确性,为进一步研究车联网技术奠定理论基础。
With the development of urban construction, dense buildings, long tunnels and other vehicles in the vehicle can only rely on GPS can not achieve full positioning, and vehicle positioning is one of the key technologies for car networking, it is also necessary to solve the car networking Difficulties. Firstly, the architecture of vehicle network, the principle of coordinated positioning of vehicles and the difficulties of positioning are introduced. Then, the calculation model of vehicle positioning in the blind area of GPS is established by the method of positioning with VSSA (Vehicle Speed & Steering Angle) Finally, the accuracy of the VSSA positioning method is verified through simulation, which lays a theoretical foundation for further research on the car networking technology.
