고객 운전 성향 맞춤형 변속 주행 제어 시스템 개발

In general, driving performance is developed to satisfy preference of average customers. But there is no single standardized setup which can fulfill various driving taste of all drivers, since it is different by gender, culture, age group, and personal habits. To resolve this issue, automotive companies have introduced selectable drive mode buttons which drivers can manually select desired drive mode among Normal, Eco, and Sport. These manual multi-mode systems are more efficient than single-mode system, but it still is a transitory solution which leads to inconvenience of requiring drivers’ effort to frequently select their preferred drive mode in volatile driving situations. Also, it is a questionable supposition that categorizing complex needs of drivers into 3 modes is sufficient. In order to overcome these problems, it is necessary to analyze individual driving style and automatically provide customized driving performance in real-time. In this paper, we introduce fuzzy algorithm of evaluating user’s short-term and long-term driving propensity by analyzing various vehicle signals and development result of smart shift & drive control system which is capable of varying powertrain and chassis control based on personal driving style adaptation and road environment to provide optimal driving performance and experience.
