摘要

Current driving comfort evaluation methods are mainly focused on road alignment and vehicle acceleration, without considering a driver's visual information. However, the driver's visual information obtained from the road environment is not completely consistent with the actual road information. Thus, it is significant to evaluate driving comfort from a driver's visual perception. In this paper, the driver's visual lane model is established based on the CatMull-Rom spline. Shape parameters of the visual lane model are the length and the curvature of the visual curve. The real vehicle experiment data is used to analyze the relevance between shape parameters and the lateral change of car acceleration. The threshold value of lateral acceleration is determined by a Bayesian credible interval, and the evaluation method of urban road driving comfort contributes to enhancing and improving urban road designs.
