Problems solved by technology
The industry provides a technical solution for scene judgment based on high-precision sensors, high-precision positioning systems, and high-precision maps. However, this solution requires positioning accuracy to reach the lane level, and the production of high-precision maps is relatively complicated, and the amount of information collected is relatively large. Large, the production technology is immature, and has not been widely used

The present application discloses a vehicle control method, including: receiving a positioning result sent by a vehicle positioning system and road condition information sent by a front-view camera, the positioning result including the current position and attitude of the vehicle, and the road condition information Including lane information, obstacle information and traffic sign information in front of the vehicle's driving direction; according to the positioning result, the road condition information, the vehicle body signal obtained from the controller area network bus and the navigation map, use the electronic fence algorithm to determine the current Whether the scene is suitable for automatic driving on high-speed elevated road main roads, the vehicle body signal represents the motion state of the vehicle, and the electronic fence algorithm is used to determine whether to enable or disable the automatic driving. Due to the use of multi-faceted information fusion for judgment, it has high reliability and does not need to rely on high-precision maps, which greatly reduces costs. The application also discloses a corresponding vehicle control device.
Description
technical field [0001] The present application relates to the field of automatic driving, and in particular to a vehicle control method and device. Background technique [0002] Electrification, intelligence, and networking are the three major trends in the technological development of the automotive industry. Among them, intelligence refers to the realization of environmental perception, global / local path planning, and vehicle control through sensor technology, graphic recognition technology, electronic and computer technology, and control technology. Through intelligence, automatic driving of vehicles can be realized, including automatic integration into traffic flow, obstacle avoidance, adaptive cruise and emergency parking. [0003] At present, the industry divides automatic driving into five levels from L1 to L5 according to the degree of automation. The L1 level means that the automatic system can sometimes assist the driver to complete certain driving tasks, such as ...
