P Jones Vehicle Dynamics and Control 2009 Cambridge University Slide 3 Vehicle Driveability Definition and Case Study Driveability is a complex attribute, the official JLR definition is: The ability to drive the vehicle smoothly, with no jerkiness or hesitation under all driving conditions, especially while shifting gear and/or controlling the accelerator pedal Introduction to Vehicle Case Study Fore-aft vehicle oscillations felt at seat-rail during cold environment testing (CET) in Sweden Oscillations induced during 70% throttle take-off on Polished Ice & Split-µ surface transition Oscillations still apparent with active systems off (HDC + ABS + TCS) Issue apparent on all Powertrain variants Test Video : Vehicle_Ice_Pullaway_Test-1.wmv J Pawar, S Biggs, R.
