Sharing method and device of vehicle positioning information, and automobile

Abstract

The invention discloses a sharing method and device of vehicle positioning information, and an automobile. The sharing method of the vehicle positioning information comprises the following steps: judging whether a signal of a global positioning system GPS positioning device is detected; when not detecting the signal of the GPS positioning device, acquiring real-time location information by combining the positioning information acquired before the interruption of the signal of the GPS positioning device with a gyroscope; and sending out the real-time location information in a broadcast way. Onthe one hand, the real-time location information can be continuously acquired by combining the gyroscope even if the GPS positioning device is offline, and the accurate acquisition of the real-time location information is ensured; on the other hand, the interaction information content between the vehicles is reduced, the accuracy of the information reaching the vehicle is ensured, and the drivingaccident caused by information error is avoided.

Description

technical field [0001] The present disclosure relates to the information sharing technology of the Internet of Vehicles, in particular, to a method and device for sharing vehicle positioning information, and a vehicle. Background technique [0002] Vehicle-to-vehicle (V2V for short) and vehicle-to-X (V2X for short) architecture-based autonomous driving technology is an important research direction in the future autonomous driving field. At present, the automatic driving technology of V2V and V2X framework is to share driving state information between vehicles, including acceleration, deceleration, steering, etc. [0003] However, the near-field communication technology with a large amount of information in the V2V and V2X architectures is developing slowly. In the 100-meter-level area, there are still great technical difficulties in exchanging driving states and determining each other's positions between driving vehicles. On the one hand, based on In the large amount of inf...

Problems solved by technology

[0003] However, the near-field communication technology with a large amount of information in the V2V and V2X architectures is developing slowly. In the 100-meter-level area, there are still great technical difficulties in exchanging driving states and determining each other's positions between driving vehicles. On the one hand, based on In the large amount of information interaction of near field communication technology, frame errors and delays occur randomly every second, and the accuracy of the information when it reaches the receiving vehicle cannot be guaranteed. The danger exists at any time during the driving of the vehicle, which may cause serious accident
