Problems solved by technology

[0003] The current prediction method for the duration of driving risk only analyzes the duration of driving risk at the previous moment, so it cannot accurately predict the duration of driving risk in the Internet of Vehicles, and thus cannot accurately warn of the existence of driving risk in smart vehicles

Abstract

Embodiments of the present application provide a method and device for early warning of intelligent vehicle driving risks. The early warning method of the driving risk of the intelligent vehicle includes: obtaining the current duration data of the driving risk of the intelligent vehicle, and obtaining a plurality of historical duration data of the driving risk of the intelligent vehicle; according to the multiple historical duration data of the driving risk and the obtained The current duration data of the driving risk, determine the probability distribution of the driving risk target duration of the intelligent vehicle; perform sampling according to the probability distribution of the driving risk target duration of the intelligent vehicle, and determine the driving risk target duration of the intelligent vehicle A predicted value of time; if the predicted value is greater than a predetermined threshold, a driving risk warning notification is generated. The technical solution of the embodiment of the present application can improve the accuracy of predicting the duration of the driving risk of the smart vehicle, and further improve the accuracy of early warning of the driving risk of the smart vehicle.

Description

technical field [0001] The present application relates to the technical field of Internet of Vehicles, in particular, to a method and device for early warning of intelligent vehicle driving risks. Background technique [0002] In the field of Internet of Vehicles, the prediction of the duration of driving risk is an important basic data for intelligent vehicles to carry out early warning of driving risk. The current prediction of the duration of driving risk mainly obtains the measured value and estimated value of the duration of driving risk at the previous moment, and determines the estimation error according to the measured value and estimated value of the duration of driving risk at the previous moment. Then predict the current moment to obtain the estimated value of the duration of the driving risk at the current moment, and then determine the real estimated value of the duration of the driving risk at the current moment according to the estimated value of the duration ...
