Abstract

The invention discloses an anger driving detection and safety warning method. Vehicle driving information comprising driving speed, longitudinal acceleration and transverse acceleration, is collected;an anger driving database is established; and a driving state of a to-be-tested sample is detected through adoption of a KNN algorithm. When driving parameters of the to-be-tested sample approach toanger driving parameters, the to-be-tested sample is judged as anger driving. A driver is prompted to control emotion through sound warning, so the driving safety is ensured. The method is characterized by feasibility and accurate anger driving detection.

Description

technical field [0001] The invention belongs to the field of automobile driving detection, and in particular relates to a detection method of a driver's intense driving behavior and an early warning method thereof. Background technique [0002] With the rapid development of my country's economy and the improvement of people's living standards, the number of motor vehicles keeps increasing every year. While facilitating people's travel and promoting economic development, it also brings more risks to traffic safety, and the number of traffic accidents is huge. The driver is a direct participant in the traffic, and the driver's influence on traffic accidents is the main part. Research shows that the driver's cause accounts for more than 90% of the causes of traffic accidents, of which angry driving accounts for 3%-5%. The traffic problems in big cities lead to obvious anger of drivers, triggering bad driving behaviors and causing serious traffic safety risks. Therefore, angry ...
