Abstract

The driving behavior evaluation method and system of the present invention include: collecting the first driving behavior data of the driver within a collection time period; performing a preprocessing operation on the first driving behavior data; sorting the first driving behavior data according to the order of collection time; Based on the first driving behavior data, calculate the standard deviation of the speed change rate distribution, the accelerator pedal opening change rate distribution standard deviation, the brake pedal opening change rate distribution standard deviation, the steering wheel angle change rate distribution standard deviation, and the driver fatigue state distribution standard deviation , obtain the driver’s second driving behavior (running a red light or speeding behavior) data within the collection time period, count the number of times the driver violated the traffic rules, and query the second driving behavior evaluation value corresponding to the number of violations of the traffic rules, Calculating the driver's first driving behavior evaluation value for the first driving behavior data, and calculating the driver's driving behavior evaluation value can comprehensively, accurately and objectively reflect the driver's driving level.

Description

technical field [0001] The invention relates to the technical field of driving behavior evaluation, in particular to a driving behavior evaluation method and system. Background technique [0002] With the rapid development of Internet of Vehicles technology, by analyzing various signal indicators of vehicles on the way, users' driving behavior can be evaluated, and the evaluation results can be used for the specific implementation of UBI (Usage Based Insurance) auto insurance, making it reasonable to formulate user-based insurance policies. Pricing of auto insurance on driving behaviour. [0003] In the prior art, the evaluation of the driver's driving behavior mostly focuses on the driver's bad driving behavior, through simple statistics on driving behavior data, such as rapid acceleration, rapid deceleration, sharp turn, speeding or advanced driver assistance system (Advanced Driving Assistant System (ADAS) alarms and other driving behavior data reflect the user's driving...
