A comprehensive evaluation of the performance of four jackknife control systems is presented. Each device is described in detail and was tested in land change and circular turn maneuvers with braking conditions designed to cause a tractor jackknife or trailer swing. The devices tested were the Hope Anti-Jackknife Device, the Breeze Jackknife Control, the Safe-T-King Anti-Jack-Knife Device, and the Kelsey-Hayes Skid Control System. The Mather Anti-Jackknife Device was not available and was evaluated comparatively based on simulation analysis. Several methods of evaluation are presented including distance and time out of lane, a speed safety margin, yaw rates and a general evaluation based on the changes in dynamic characteristics caused by the devices. The results of this research indicate that all of the devices offer some improvement in a jackknife situation with the wheel antilock system the only method that prevented a jackknife throughout the test program.
