Problems solved by technology
[0003] At present, in related technologies, the threshold judgment is usually performed by three parameters: longitudinal acceleration, lateral acceleration, and vertical acceleration, and the samples used in the threshold extraction process are limited, and finally provide the total score of driving behavior, or provide a safe or unsafe judgment result However, there are few index parameters for evaluation, and it cannot provide the degree of influence of each index on the occurrence of danger during vehicle driving, and the accuracy of the evaluation results has not been well verified, and only the total score or judgment of driving behavior is given. The result is not conducive to the driver's understanding of weak driving behaviors, and cannot effectively help users correct their bad driving behaviors

The invention discloses a driving behavior scoring method and device. The method comprises the steps: obtaining the vehicle driving data of a to-be-scored distance, and determining a first score of each index according to an alarm parameter value of each index; carrying out the weighted summation of the first scores of all indexes, so as to obtain a first scoring result of the to-be-scored distance; determining a state type of the to-be-scored distance according to a pre-trained neural network model and the alarm parameter value of each index; Carrying out the adjustment of the first scoring result of the to-be-scored distance and the first score of each index according to a preset scoring adjustment standard and the state type, so as to generate a second scoring result of the to-be-scored distance and a second score of each index, wherein the second scoring result serves as the scoring result of driving behaviors. The method carries out the adjustment of the total score of the to-be-scored distance and the scores of all indexes through the neural network model, and improves the calculation accuracy of the scores.
Description
technical field [0001] The invention relates to the technical field of automobile safety driving, in particular to a driving behavior scoring method and device. Background technique [0002] With the improvement of living standards, the number of motor vehicles is also increasing. In the process of driving vehicles, unsafe driving behaviors have brought many safety hazards and caused huge property and personnel losses. Therefore, how to improve Driver's driving behavior has become a problem that cannot be ignored. [0003] At present, in related technologies, the threshold judgment is usually performed by three parameters: longitudinal acceleration, lateral acceleration, and vertical acceleration, and the samples used in the threshold extraction process are limited, and finally provide the total score of driving behavior, or provide a safe or unsafe judgment result However, there are few index parameters for evaluation, and the degree of influence of each index on the occur...
