Embodiment Construction

[0046] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0047] Any feature disclosed in this specification (including any appended claims, abstract), unless otherwise stated, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0048] Such as figure 1 As shown, this embodiment discloses a method for constructing a vehicle speed abnormal early warning model based on the Internet of Vehicles, including the following steps:

[0049] A. Steps of screening speed data from the speed data uploaded by each vehicle;

[0050] B. The step of extracting the velocity components from the velocity data screened by each vehicle;

[0051] C. For the speed components extracted by each vehicle, the step o...

Abstract

The invention discloses a pre-warning model and method for vehicle speed abnormity and based on car networking and a model building method. The model building method comprises a step of screening speed data, a step of abstracting speed components, a step of calculating speed difference components, a step of grouping the speed difference components and a step of calculating safe sections using a quartile method and building the pre-warning model. The pre-warning method for the vehicle speed abnormity comprises a step of obtaining the speed data of a to-be-detected vehicle, a step of calculatingthe speed difference components and a step of using the referred pre-warning model for pre-warning detecting the speed difference components. According to the pre-warning model and method for the vehicle speed abnormity and based on the car networking and the model building method, continuous and all-round vehicle speed abnormity detecting can be carried out aiming at vehicle speed grades, the detecting effect is more comprehensive, and the pre-warning effect is more precise.

Description

technical field [0001] The invention relates to the field of the Internet of Vehicles, in particular to an early warning model, method and model construction method for abnormal vehicle speed based on the Internet of Vehicles. Background technique [0002] Determination of abnormal speed behavior is often an after-the-fact inspection. Currently on the market, there is no mature early warning technology for dealing with abnormal vehicle speeds. The traffic police department infers the abnormal driving situation of the vehicle before the vehicle accident through a large number of vehicle accidents. A large number of car manufacturers will also pass a large number of crash tests to understand the abnormal speed range of the vehicle before the new car leaves the factory. This post-mortem inspection or manufacturer's crash test will consume a lot of manpower and material resources. Moreover, the experimental data can only illustrate theoretical issues. In actual vehicle drivin...
