Characteristic Velocity Stability Indicator for Passenger Cars
Published April 19, 2004 by University of Salerno in Italy
A precise knowledge about the current driving condition is getting increasingly important for future driver assistance systems to support the prevention of any critical driving situation. Moreover a precise knowledge about the driving situation can be used in testing and comparing new passenger cars. After a short introduction of a lateral vehicle model, an analytical approach for an online calculation of different driving conditions (i.e., stability, understeering, oversteering, and neutralsteering) is given. A characteristic velocity stability indicator is defined, which allows online computation of the present driving condition. Real test drives show the application.
