This IDEA project designed a differential (side-to-side) braking system for limited authority lateral maneuvering that can support active ITS vehicle control systems aimed at preventing unintended road departure events. The vehicle is steered left or right by means of braking forces appropriately applied to either side of the vehicle by a control algorithm. The traditional control channel used by drivers to steer the vehicle-the steering system-is not interfered with or modified. The work under this project concentrated on development of the control algorithm using computer simulation to demonstrate the effectiveness of the concept under different operating conditions (speeds and surface friction). Initial vehicle track tests supported the analysis by providing estimates of how a representative vehicle would respond to differential braking at various speeds and application pressures. In general, the findings indicate that the control algorithm developed under this IDEA project is shown to be effective in controlling a representative passenger car mitigating unintended road-departure events.
