Development of Smart Shift and Drive Control System Based on the Personal Driving Style Adaptation

In general, driving performance is developed to meet preference of average customers. But there is no single standardized guideline which can satisfy various driving tastes of all drivers whose gender, cultural background, and age are different. To resolve this issue, automotive companies have introduced drive mode buttons which drivers can manually select from Normal, Eco, and Sport driving modes. Although this multi-mode manual systems is more efficient than single-mode system, it is in a transient state where drivers need to go through troubles of frequently selecting their preferred drive mode in volatile driving situations It is also doubtful whether the three-categorized driving mode can meet complex needs of drivers.. In order to settle these matters, it is necessary to analyze individual driving style automatically and to provide customized driving performance service in real time. In this paper, we adopted fuzzy algorithm to evaluate user’s short- and long-term driving tendency by analyzing various vehicle signals. We also came with a result of developing a smart shift and drive control system capable of changing power train and chassis control based on personal driving style and road condition to provide drivers with optimal driving performance and experiences.
