Embodiment Construction
[0150]Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0151] Before introducing the embodiments of the present disclosure in detail, firstly, the technical background used in the present disclosure will be described. With the development of science and technology, the continuous development of concepts such as automobile automatic driving, intelligent transportation, and smart cities has produced many new types of intelligent Nouns in the field of transportation technology, such as the above-mentioned V2X interactive communication technologies such as V2V, V2I, and V2P, through which an intelligent transportation system (ITS, English: Intelligent Transport System) can be realized. Among them, V2X is the key techn...

The invention relates to a danger judgment method and device of roads. The danger judgment method obtains a relative positional relationship between a hazard source and a visual identification unit by the visual identification unit and confirms whether the hazard source is located in a hazardous area or not based on the relative positional relationship. When the hazard source is located in the hazardous area, the relative movement direction of the hazard source is determined, and a geographical position coordinate of the hazard source is determined according to the geographical position coordinate and the relative positional relationship of the visual identification unit, and then the geographical position coordinate and the relative movement direction of the hazard source are sent to a target vehicle, thus the target vehicle is allowed to judge that whether the target vehicle and the hazard source has correlation about the direction, the position and the distance according to the geographical position coordinate of the hazard source and the target vehicle itself, in this way, it is judged that whether the hazard source is in danger or not, when the hazard source is in danger, a danger hint is outputted.
Description
technical field [0001] The present disclosure relates to the technical field of vehicles, in particular to a method and device for judging road hazards. Background technique [0002] In recent years, with the introduction and continuous development of concepts such as automobile automatic driving, intelligent transportation, and smart city, the inter-vehicle communication technology has been rapidly matured and developed. At present, the intelligent cooperation system based on V2X (English: Vehicle to X, Chinese: vehicle-other equipment) is one of the best foreseeable ways to improve the efficiency of the transportation system and the safety of travelers. V2X can use DSRC (English: Dedicated Short Range Communications, Chinese: dedicated short-distance communication) technology communicates between multiple vehicles, infrastructure, and pedestrians, which are V2V (Vehicle to Vehicle, car-car), V2I (English: Vehicle to Infrastructure, car-basic Facilities) and V2P (English: ...
