Problems solved by technology
[0004] In the past, the risk of driving safety could only be judged simply by relying on some basic information of vehicles and drivers and past claims information. Therefore, it is difficult to realize the risk control and safety control of drivers and the effective management of high-quality and non-high-quality drivers.

The present invention provides a prediction model training and prediction method, device, electronic equipment, and storage medium. The driving safety risk prediction model training method includes: for M vehicles, obtaining the accident data of each vehicle, and at least according to the driving dynamic data and vehicle data , driver data and environmental data obtain multiple features of each vehicle, and use these multiple features of each vehicle as the feature vector of the vehicle, and the feature vectors of the M vehicles form a sample set; using the sample set and The corresponding emergency data trains the first prediction model of the first layer and the second prediction model of the first layer; when using the sample set to train the first prediction model of the first layer and the second prediction model of the first layer, the first prediction of the first layer The output of the model and the output of the first-layer second prediction model and the corresponding emergency data training train the second-layer prediction model. The method and device provided by the present invention realize the safety control of the driver's risk control and the effective management of high-quality and non-high-quality drivers.
Description
technical field [0001] The present invention relates to the field of big data technology, in particular to a prediction model training and prediction method, device, electronic equipment, and storage medium. Background technique [0002] As a basic industry of the national economy, the logistics industry integrates multiple industries such as road transportation, warehousing and information, and involves a wide range of fields. Among them, driving safety accidents involving the driver's life still need special attention. The total number of traffic accidents in my country is still high every year, and trucks cause about one-third of the traffic accident deaths. In recent years, the proportion of highway traffic accident deaths to the total number of road traffic accident deaths in my country has remained at about 10%. Usually through on-board OBD (On-Board Diagnostic) equipment or smart phones and other equipment, the sensors in the equipment can obtain vehicle driving dat...
