Abstract

The invention provides a driving safety reminder method, device and medium based on CAN data. Based on the collected CAN data of all vehicles in the fleet and the division of line space and time, the present invention defines threshold judgment rules to automatically generate irregular driving behavior rule thresholds, and updates the irregular driving behavior rule thresholds to vehicle-mounted devices in real time , when the irregular driving behavior rule threshold is exceeded, the driver will be prompted by voice, and the hidden Markov model (HMM) and k-means clustering method are also used to filter the misjudgment in the irregular driving behavior, and the statistical analysis of the driving Traffic safety can be improved through the present invention.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a driving safety reminder method, device and storage medium based on CAN data. Background technique [0002] Currently, drivers' driving habits are closely related to vehicle safety hazards, fuel consumption and vehicle service life. The fuel consumption of drivers with good driving habits will be lower than that of other drivers, and the probability of potential safety hazards will also be reduced; because of good driving habits, the service life of the vehicle will also increase accordingly. Therefore, it is very necessary to monitor and regulate the driver's driving behavior. [0003] In the existing technology, it is generally based on a fixed rule algorithm, which cannot automatically adjust according to changes in road conditions or external environment, and cannot perform statistical analysis of bus routes and drivers’ irregular driving behaviors, and t...
