Abstract

A safe navigation system includes a planning unit for planning a navigation path for vehicles according to road information and road condition information, a matching unit for matching lanes and positioning lanes wherein the vehicles located, a collecting unit for collecting data information of surrounding vehicles in a preset scope S, an identification unit for acquiring road early warning information and identifying conflicted vehicles according to the data information of the surrounding vehicles, a judging unit for judging whether the conflicted vehicles or road early warning information exists, and a display unit for highlighting displaying or voice prompting of the conflicted vehicles or the road early warning information when the judging unit judges that the conflicted vehicles or the road warning information exists. The safe navigation method and system can provide own positions and motion information, at the same time, reflect the position relation of the surrounding related vehicles, highlightingly display the conflicted vehicles and the road early warning information, and provide a decision support for users on the way of vehicle driving; and moreover, with lane-level safe navigation, early warning precision can be improved, and the user experience is increased.

Description

Technical field [0001] The invention relates to the field of Internet of Vehicles, in particular to a safe navigation method and system. Background technique [0002] At present, navigation systems are mainly used to provide travelers with pre-trip route planning and real-time guidance during the trip. Some navigation systems can provide static warning information such as real-time road conditions, road speed limit information, and red light captures. The main purpose of the existing navigation system is still to shorten the travel time and improve the travel efficiency of travelers. The safe road warning information provided is very limited, and they are all subsidiary functions. However, with the rapid development of the Internet of Vehicles and smart cars, the connections between people, cars, and roads are getting closer, and travel safety will also become another important factor that needs to be considered in navigation systems. [0003] The existing navigation system only p...
