Abstract
A brake control system/method for preventing or arresting and minimizing trailer-swing and jackknife in an articulated vehicle (10) is provided. The control system/method senses or calculates values indicative of articulation angle (AA) and time derivatives thereof (dAA/dt, d.sup.2 AA/dt.sup.2) and processes same to sense conditions indicative of the onset of a trailer brake induced trailer swing event or of a tractor brake induced jackknife event.
