Research on probability index of road driving comfort based on driving vibration distribution

Driving comfort is a research object involving human factors, the evaluation process is dependent on human factors, and the evaluation results have probability characteristics. Firstly, the related research on pavement performance perception using smart phones were summarised. On this basis, the driving data acquisition experiment was carried out, the smartphone is used as the driving data acquisition equipment, the probability representation method of driving comfort of pavement evaluation unit based on driving vibration process and vibration comfort is studied, and a comfort classification range of the vector synthetic vibration index was determined comprehensively. Finally, the comfort probability of different vibration ranges was quantified with reference to the Sigmoid function. From the point of view of the distribution of driving vibration, the probability evaluation index F of driving comfort with the influence of vibration difference was put forward, which reflects the possibility for drivers to evaluate the road section in terms of driving comfort.

Automated summary

Driving comfort is a research field that involves human factors and relies on human evaluation. The research summarized previous studies on pavement performance perception using smartphones. Based on this, a driving data acquisition experiment was conducted using smartphones, and the probability representation method of driving comfort based on driving vibration process and vibration comfort was studied. Furthermore, a comprehensive comfort classification range for the vector synthetic vibration index was determined. Finally, the comfort probability of different vibration ranges was quantified using the Sigmoid function, and an evaluation index for driving comfort was proposed considering the influence of vibration difference.
