Abstract | ||||
ABSTRACT This paper presents a new control strategy called "Semitrailer Differential Braking Technique (SDBT)" to improve the dynamic stability of 2 axle tractor combined with 3 axle semitrailer equipped with a standard antilock braking system (ABS) during evasive maneuver at high speed. A Matlab Simulink model constructed to study the dynamic stability under different driving conditions; brake sequence, driver input, steering response, road type, and loading condition. The new concept based on monitoring of the yaw rate difference between the tractor and semitrailer, and applying differential braking on the semitrailer at certain articulation rate threshold. The results show improving of the handling performance of the combination against rollover and jackknifing during evasive maneuver at high speed. | ||||
