METHOD AND SYSTEM FOR IMPROVING MOTOR VEHICLE STABILITY INCORPORATING AN ELECTRIC POWER STEERING SYSTEM

摘要

A method and system for stabilizing a vehicle system employing an electric power steering system (EPS) is disclosed. The method includes receiving as inputs (4), a desired torque command (T¿cmd¿) representative of a steering wheel torque (T¿d?) and a vehicle speed signal (u). The method also includes acquiring an acceleration signal (r) representative of vehicle acceleration. The method further comprises generating an assist torque command (f1), which is a combination of the desired torque command (Tc) and a compensating torque command (Ta) where the compensating torque command (Ta) is responsive to the vehicle speed signal (u) and the acceleration signal (r).
