In order to solve the problem that the existing technology cannot achieve all-weather positioning and navigation, and that 3D high-precision maps are difficult to effectively adapt to environmental changes and affect positioning accuracy, the embodiments of the present invention provide an autonomous driving navigation method, device, system, vehicle-mounted terminal and server.

专利摘要显示，该方法包括：无线网络中的无线基站向车载终端发送差分定位改正数(202)；车载终端获取车辆的卫星定位数据，从无线网络的无线基站接收差分定位改正数，采用差分定位改正数对卫星定位数据进行修正，得到车辆的高精度位置，车载终端向服务器发送高精度位置(204)；服务器从车载终端接收高精度位置，根据高精度位置并结合高精度地图信息，确定车道级规划行驶路径，服务器向车载终端发送车道级规划行驶路径(206)；车载终端从服务器接收车道级规划行驶路径，根据获取的高精度位置，控制车辆按车道级规划行驶路径自动驾驶(208)。采用基于无线网络辅助的卫星差分定位技术，实现了全天候全路况的自动驾驶导航，且定位精度无需依赖于3D高精度地图，方案的适应性和可靠性显著增加。

The content of Qichacha shows that as early as November 30, 2015, Huawei had applied for a patent for "autonomous driving navigation method, device, system, vehicle-mounted terminal and server". The patent was disclosed on May 11, 2018 and was authorized on June 1, 2021.

Currently, Huawei is also strengthening its cooperation with other companies.

In the field of intelligence, Changan Automobile and Huawei have carried out comprehensive and in-depth cooperation on more than 10 forward-looking technologies including L4 autonomous driving, 5G vehicle networking, and C-V2X.

The cooperation between Ankai Bus and Huawei in the field of intelligent networking and autonomous driving is currently mainly in the field of autonomous driving computing platforms. Ankai's independently developed intelligent driving system is equipped with Huawei's computing platform MDC300/F series, relying on the high computing power and strong engineering capabilities of Huawei's autonomous driving domain controller to assist Ankai in advancing its autonomous driving system research and development capabilities.
