Abstract: This paper presents a new control strategy called "Semitrailer Differential Braking Technique" (SDBT) to improve the stability of a two-axle tractor combined with a three-axle semitrailer equipped with a standard Antilock Braking System (ABS) during evasive manoeuvres at high speed using a new validated Simulink program. The new concept is based on monitoring of the yaw rate difference between the tractor and semitrailer and applying differential braking on the semitrailer at a certain articulation rate threshold. The new proposed control strategy will make the semitrailer act as smart equipment regardless of the tractor type, because tractors and semitrailers are built by different manufacturers.
