On nonlinear model predictive direct yaw moment control for trailer sway mitigation

open access: yesVehicle System Dynamics, 2022
In car–trailer combinations, the hitch angle is the relative yaw angle between towing car and trailer. The literature has shown that the inclusion of the hitch angle measurement for the feedback control of trailer oscillations can bring safety benefits, compared with conventional trailer sway mitigation algorithms based on the yaw rate of the car ...
