E:\13_GS 350-450h...\Press Previews\13_Lexus_GS_LLPP_v7-5_wide.ppt 11 2013 Lexus GS 11/7/2011 INTERIOR DESIGN CONCEPT • Creates a space that always gives a sense of excitement and the anticipation of driving the moment you open the door. • Provides space where the driver can immediately understand all the functions and how they operate as soon as he or she sits down. • With the aim to achieve this, the development team returned to the Human Machine Interface (HMI) concept advocated by Lexus and began by rebuilding a “human-centered interior” to incorporate technology that anticipates human emotions, rather than space in which humans must adapt to the machines. • The display zone, which includes the meters, etc., was clearly separated from the operation zone, centered around the Remote Touch Interface that allows the driver to operate the vehicle with a natural posture and minimal movement of the driver’s line of sight. • A feeling of openness is created by the instrument panel’s horizontal line. The wide horizontal instrument panel has a powerful yet simple design and gives a sense of stability.

DIFFERENCES FROM THE CONVENTIONAL CONTROL SYSTEM • With conventional control systems the four wheels are treated independently and vehicle behavior in the direction of heave was controlled at each of the wheel positions. • The new system controls oscillation behavior at all four wheels simultaneously in a linked manner. • This enables oscillation control not only in the heave direction, but also in the directions of roll and pitch. REBOUND CONTROL • Based on signals from a vertical G sensor, oscillations are detected in the directions of heave, roll and pitch due to inputs from the road surface. • By controlling damping force on all four wheels with non-linear H-infinity control logic to suppress oscillations in three directions, rebound is naturally smoothed out, helping assure excellent ride comfort.
