Transient forewarning method and device for road risk event

Abstract

The embodiment of the invention provides a transient forewarning method and device for a road risk event. The method comprises the steps of receiving a road risk event published by a publisher, determining a forewarning level of the road risk event according to the risk type of the road risk event, determining a forewarning strategy of the road risk event according to the risk type and the forewarning level of the road risk event, and finally feeding the forewarning strategy back to a driver. According to the method and device, the most road risk events can be recognized and forewarned withoutdepending on a plenty of vehicle-mounted equipment or roadside equipment, and the method and device are low in application cost and easy to popularize; meanwhile, aiming at the road risk events withdifferent risk types and forewarning levels, the different forewarning strategies are used for forewarning, the driver is facilitated to accurately and intuitively acquire the information of the roadrisk event, and thus the driver can cope with the road risk event in time, and the occurrence of potential accidents and secondary accidents can be effectively avoided.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, and more specifically, to a transient early warning method and device for road dangerous events. Background technique [0002] Cars are an indispensable element in people's lives. According to incomplete statistics, the number of motor vehicles in China has reached 310 million, of which 217 million are cars; the number of motor vehicle drivers has reached 385 million, of which 342 million are car drivers. The driver's driving experience can reduce potential safety hazards during driving, but due to various subjective and objective factors, potential safety hazards during driving cannot be completely eliminated. There is icing ahead and roadside construction ahead on the road and so on. With the development of technologies such as smart cars, unmanned driving, and vehicle-road coordination, how to reduce potential safety hazards during driving has become a hot spot of a...
