Active handling enhancement for chassis control systems

Abstract: Active steering control is the next step for vehicle safety. Since steering control is continuously active without dead-bands, it helps to maintain predictable response before ESC brake systems intervene. A unified Dynamic Feed-Forward (DFF) algorithm is developed for chassis control systems with a tunable second-order reference model. The resulting control law is third order or sixth order when the tyre dynamics are included. The use of a reference model makes it readily compatible with the ESC systems. A validated vehicle dynamic model is used to study the handling and rollover benefits of DFF applied to steering and braking systems.
