Stability Control on Tractor Semi-trailer during Split-mu Braking
Handling behaviour of articulated vehicles combination is more complex and less predictable than that of non-articulated vehicles.It is usually difficult for drivers to maneuver a tractor semi-trailer during high speed emergency braking on split-mu road surface.Braking on this type of road surface,the conventional anti-lock braking systems will cause the vehicle deviate from the desired direction,or overmuch stopping distance.In this paper,a 3-dof of tractor semi-trailer model was used to produce desired yaw rates which were compared with actual yaw rates.An active front steering control and four-channel ABS were integrated to improve the tractor semi-trailer lateral stability while braking on split-mu road surface,which will produce maximum braking force.A full function tractor semi-trailer model was built and assembled in multi-body dynamics software,and the dynamic analysis was performed on split-mu road surface.The simulation results show that the integrated system can improve the tractor semi-trailer lateral stability under braking on split-mu road surface.
