Problems solved by technology
At present, most of the warning methods related to driving behavior are to install various sensors, obtain relevant data, and remind users to pay attention to the current driving in real time. They lack the evaluation of users' long-term driving habits and cannot effectively help users correct their bad driving behaviors.

Embodiment Construction
[0051] 1) Assume that there is a Mr. Wang, who is equipped with the product of the present invention on his car, and the score after a certain driving is: P b =70, P a =80,P t =100, P r =80,P v =70, P d =80.
[0052] Assuming that after calculation, the weight of each indicator in this period is: W b =15%, W a =20%, W t =20%, W r =15%, W v =20%, W d =10%.
[0053] Then the total score after this driving is: 70×15%+80×20%+100×20%+80×15%+70×20%+80×10%=80.5
[0054] 2) Mr. Wang had multiple driving behaviors this month, determine the specific number of driving times and each score, as shown in the following example
[0055]
[0056] Assuming that after calculation, the average score of Mr. Wang this month
[0057] 3) Determine the number of violations and parts replacement scores for this month, assuming that they are P q =70,P l =100;
[0058] According to experience and user needs, the weight values are obtained as follows: W q =25%, W l =15%, then Mr...

The invention relates to a driving behavior warning method based on vehicle bus data. The driving behavior warning method based on vehicle bus data is characterized by comprising an iOBD terminal and an iOBD monitoring platform, wherein the iOBD terminal provides the following data according to the driving state: sudden brake times (b), sudden acceleration times (a), sudden turning times (t), rotating speed (r), average speed (v) and driving distance (d); the iOBD terminal transmits the data information to the iOBD monitoring platform; the iOBD monitoring platform performs statistics and analysis on the driving behavior data of a user and determines the comprehensive driving behavior score of the user; and the iOBD monitoring platform transmits the comprehensive driving behavior score of the user to a mobile phone of the user to serve as the basis of judging advantages and disadvantages of long-term driving behavior, prompts according to the score and triggers warning according to the real-time data. By the driving behavior warning method based on vehicle bus data, the driving behavior score of the user is calculated according to the preset user driving behavior statistics analysis model. The driving behavior warning method based on vehicle bus data has the advantages that the advantages and the disadvantages of the driving behavior of the user can be judged; an analysis report is formed and transmitted to the user; and the driving safety of the user is greatly improved.
Description
technical field [0001] The invention relates to a driving behavior warning method based on vehicle bus data. Background technique [0002] Statistics on road traffic accidents at home and abroad show that more than 70% of accidents are directly caused by drivers. The analysis of the causes of accidents shows that there is a strong correlation between driving behavior and traffic accidents. Therefore, it is necessary to carry out in-depth research on driving behavior to improve the level of traffic safety. [0003] At present, there are many warning methods to driving behavior at home and abroad. For example, Toyota uses the steering wheel angle sensor and pulse sensor for signal collection, and alerts the driver through hearing, vision and vibrating the seat. The anti-drowsiness system installed by Mercedes-Benz on its E-class sedans inputs actions with a high degree of correlation into the system. Once the system detects that the driver has similar driving behavior, it w...
