The invention discloses a warning method of a road condition, a warning system of the road condition, a cloud server and a vehicle. The warning method of the road condition includes the following steps that: the cloud server carries out segmentation processing on a road with a preset distance; the cloud server collects road segment information of each segmental road, wherein the road segment information contains accident occurrence information, vehicle braking pedal opening degree information, vehicle deceleration information or warning flag information; the cloud server carries out accident level grading on the segmental roads according to the road segment information; when a vehicle is to enter one segmental road, a vehicle-mounted terminal obtains the accident grade of the segmental road from the cloud server; and the vehicle-mounted terminal carries out corresponding warning prompting for the vehicle according to the accident grade. With the warning method provided by the embodiments of the present invention adopted, when a vehicle is to drive to one segmental road, the driver of the vehicle is prompted according to the accident grade of the segmental road, so that the driver can concentrate his or her attention or slow down as soon as possible to prevent an accident.
Description
technical field [0001] The invention relates to the field of traffic technology, in particular to a road condition warning method, system, cloud server and vehicle. Background technique [0002] In recent years, road traffic has developed rapidly, and many remote areas are accessible by road. However, due to terrain and economic conditions in many areas, especially in remote mountainous areas, many roads have steep slopes, sharp curves, uneven road surfaces, missing or unclear traffic signs, and imperfect traffic infrastructure, resulting in frequent traffic accidents. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. [0004] For this reason, an object of the present invention is to propose a warning method for road conditions, which can remind the driver in advance of the accident probability and trend of the road section when the vehicle is about to trav...
