The addition of user-customizable features to automobiles increases the need to differentiate among drivers so that each driver’s custom settings can be automatically applied. This study explored the feasibility of using component adjustment settings (e.g., seat position or steering wheel angle) to differentiate among drivers. The primary consideration in the feasibility assessment is the ratio of the within- and between-driver variance in component adjustments. Differentiation is a function of the stature difference between sharing drivers. Simulation and analysis showed that H-point fore-aft position provides the best single-component differentiation, followed by H-point up-down, steering wheel telescope and steering wheel angle. Seatback angle and seat-cushion angle are less useful in driver differentiation.
