Abstract
Vehicle drivability is now one of the keystones of product quality, and is refined aggressively to achieve vehicle brand differentiation and market position. This paper starts with the introduction of drivability’s definition, driver-vehicle interaction, and the voice of customer for purchase criteria. Then the vehicle drivability subjective evaluation method and objective characteristic metrics are illustrated. The model-based approach for vehicle drivability development during advanced vehicle development process is analyzed. The non-linear accelerator pedal-throttle-engine load relationship and longitudinal pedal-acceleration response characteristic as drivability critical factors are investigated emphatically at last.
