Abstract

The invention discloses a driving behavior risk index judgment method based on mobile phone car networking data, and belongs to the fields of Internet of Vehicles, automatic driving, vehicle insurance prediction, vehicle insurance pricing and the like. The method comprises the following steps: constructing a driving behavior visual characteristic system based on the mobile phone terminal Internet of Vehicles data; on the basis of the driving behavior intuitive characteristic system, building a dangerous driving behavior characteristic system from the angle of safe driving; and establishing a linear relationship between the driving behavior risk index and the dangerous driving behavior characteristics to construct a driving behavior risk index prediction model, and predicting the driving behavior risk index of the driver by using a dangerous driving behavior characteristic system. According to the invention, the driving behavior visual characteristic system, the driving dangerous behavior characteristic system and the driving behavior risk index prediction model are constructed, so that the driving behavior risk of the driver can be efficiently judged, and the method has certain promotion significance for perfecting and optimizing an auxiliary driving system and realizing a higher-level automatic driving technology.

Description

technical field [0001] The invention belongs to the fields of car networking, automatic driving, car insurance forecasting, car insurance pricing, etc., and more specifically relates to a method for determining a driving behavior risk index based on mobile phone car networking data. Background technique [0002] According to the development status of the autonomous driving field, the standard used globally is the five levels, L0-L4, formulated by the US National Highway Traffic Safety Administration (NHTSA). At present, many companies have developed L4-level autonomous driving technology, but when it is used in practice, failures occur frequently, such as the intersection will not change lanes, and the accident rate is high in rainy weather. New cars launched in 2021 are generally equipped with L2-level automatic driving technology, which can realize adaptive cruise control system, automatic emergency braking and other functions to assist the driver to complete the driving b...
