ABSTRACT |
To further enhance the role of connected vehicles with the Human-Machine Interface (HMI) in helping drivers
in foggy weather, it is meaningful to optimize the HMI based on the driver’s needs. In order to explore the method of HMI
optimization, this paper builds a driving simulation experimental test platform of freeway connected vehicle system,
designing two experimental scenarios according to the technical conditions (without HMI or with HMI). After that, the paper
uses Markov chain to explore the drivers’ fixation transition to identify the driver’s needs in different sections at different
conditions. Besides, combined with the visual trajectory results, the paper provides suggestions for optimizing HMI. The
results show the review rate of drivers in each section for the straight upper front area is very high. The highest value occurs
in the heavy fog zone, suggesting that HMI can provide more road information. HMI should offer a prompt to the driver
before entering the warning zone, and remind the driver of changes in the speed limit before entering the fog area. The
prompt module of HMI should shorten the horizontal length. In conclusion, this paper aims to propose a general diagnosis
method by diagnosing the self-designed HMI. |
