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.

VEHICLE SPEED-SENSING CONTROL • Controlling damping force in accordance with vehicle speed helps to achieve both ride comfort at low speed and handling stability at high speed. ANTI-DIVE CONTROL • Predicts a vehicle’s diving motion from the brake pedal operation and sets a higher damping force to help reduce the body’s dive speed. ANTI-SQUAT CONTROL • Reduces the amount of vehicle attitude change when accelerating, helping to achieve excellent ride comfort and handling stability. RUGGEDNESS-SENSING CONTROL • Reduces the damping force when rough vibration is sensed based on vertical G sensor output while driving over irregular road surfaces. UNSPRUNG MASS VIBRATION DAMPING CONTROL • Gives a higher damping force when unsprung resonance is detected based on speed sensor signal output. PRE-COLLISION SYSTEM COOPERATIVE CONTROL • When the driving support computer senses a possible collision, increased damping force is used to help reduce brake dive. VEHICLE STABILITY CONTROL COOPERATIVE CONTROL • Applies the appropriate damping force in response to vehicle side skid and friction changes in the road surface to enhance the VSC operation.

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.
