Calculating the similarity

说明：  Slip-ratio-based methods are commonly used to control the wheel torque such that the wheel dynamics is stabilized and the desired traction/braking force is attained; however, slip-ratio-based controllers are incompetent for precise longitudinal tire force tracking due to nonparametric tire model uncertainties.

python基础课程；python是一种计算机编程语言。作为一种面向对象的动态类型化语言，它最初被设计用来编写自动脚本（shell）。随着版本的更新和新语言功能的增加，它越来越多地被用于独立的大型项目的开发中。(Python Basic Course; Python is a computer programming language. As an object-oriented dynamic typed language, it was originally designed to write automated scripts (shells). With the updating of versions and the addition of new language functions, it is increasingly used in the development of independent, large-scale projects.)
