Abstract

The invention provides a road abnormal event early warning method, vehicle-mounted equipment and roadside equipment. The method is used for the early warning method of the vehicle-mounted equipment, and comprises steps of obtaining the current first vehicle condition operation data, detected by a vehicle driving sensor, of a vehicle; judging the current road condition according to the first vehicle condition operation data to obtain a first judgment result; when the first judgment result is that the road is abnormal, obtaining a first position of the vehicle; when the vehicle is located in the communication range of the roadside equipment, road abnormal event information being sent to the roadside equipment; wherein the road abnormal event information comprises the first vehicle condition operation data and the first position. Whether the current road condition is abnormal or not is judged according to the first vehicle condition running data detected by the vehicle running sensor, the requirement for light is reduced, the road condition can be judged on a weak light or dark or foggy road section, and the applicability of the early warning method for the road abnormal event can be improved.

Description

technical field

[0001] The invention relates to the technical field of road abnormality monitoring, in particular to an early warning method for abnormal road events, vehicle-mounted equipment and roadside equipment. Background technique

[0002] For urban roads or high-speed roads, some road abnormalities often occur, such as driving vehicles dropping heavy objects (such as stones, iron blocks, small equipment), causing dangerous obstacles in the road; Soil and slag) will make road vehicles slippery and unstable; another example is that the road will be damaged due to external force, and potholes will appear, which will cause road vehicles to bump and roll over when driving.

[0003] For the above-mentioned potential risks, it is necessary to discover the risk points in time and remind the vehicles to pay attention, especially on the expressway, but the work of finding the risk points is more labor-intensive. The longer the risk exists, the greater the probability of an ac...
