Abstract

The invention discloses an unmanned vehicle global path planning method and device, and the method comprises the steps: carrying out the static global path planning according to a high-precision map,a starting point and destination information, and obtaining a scheme with the shortest distance; in the track scheme with the shortest distance, adding real-time road condition information, and acquiring a scheme with the shortest dynamic driving time through the driving speed; employing the GPS / BDS satellite positioning precision factor for adjusting the driving speed, and forming the shortest-time global path planning suitable for the unmanned vehicle. Compared with a traditional method, the shortest time path obtained through the method is more suitable for the unmanned vehicle, and the hardware cost of the unmanned vehicle does not need to be increased.

Description

technical field [0001] The invention relates to the field of path planning for unmanned vehicles, in particular to a global path planning method and device for unmanned vehicles. Background technique [0002] As DARPA restarted the research on unmanned vehicle technology, and held three smart car challenges in 2004, 2005 and 2007, Google invested heavily in the research of autonomous driving technology. upsurge. Participants include top Internet companies such as Google, Apple, Uber, and BAT, as well as traditional car companies such as Tesla, Mercedes-Benz, BMW, GM, and Cadillac. At the same time, component suppliers such as Intel, Nvidia, Bosch, and Mobileye also participated , In addition, start-up companies in the field of autonomous driving have sprung up like mushrooms after rain. [0003] After more than ten years of development, autonomous driving technology has gradually evolved from laboratory research, to closed environment technology competitions, and then to f...
