The Effectiveness of Rear Axle Steering on the Yaw Stability and Responsiveness of a Heavy Truck
Artikel i vetenskaplig tidskrift, 2008

Rear axle steering (RAS) at low speed is available in heavy trucks to improve their manoeuverability and reduce tyre wear; by extending the functionality of the existing RAS to high speed turning and split-mu braking, considerable safety benefits and enhancement in driver comfort can be gained. In this study, a RAS System was developed and simulated in Matlab–Simulink which showed encouraging results. Furthermore, the developed system was implemented on a Volvo Truck and tested in a series of split-mu braking and ISO double lane change manoeuvers. The obtained results conform to the expectations.
