Active steering and unilateral braking are two common methods to enhance lateral stability of heavy vehicle combinations. For optimal allocation of braking and steering forces to different axles of the vehicle combination, an understanding of their potential is required. In this study, effectiveness of active steering and unilateral braking of all the eight axles of a truck-dolly-semitrailer in diminishing a trailer swing under a lane change maneuver is investigated. The effectiveness is measured by the resulted reduction in the offtracking and rearward amplification. Each steering and braking intervention is applied as a constant input during a fixed time interval.
