US Patent 7698034 Integrating active front steering and vehicle stability brake control

An integrated vehicle control system includes a first control system having a maximum authority to selectively operate a first vehicle sub-system and a second control system to selectively operate a second vehicle sub-system. A controller is adapted to monitor a first parameter associated with the first vehicle sub-system and a second parameter associated with the second vehicle sub-system. The controller is operable to control the first and second parameters by selectively invoking operation of the second control system when the first control system exceeds the maximum authority and the second parameter exceeds an upper threshold.
