1. An integrated vehicle control system, comprising:
- a first control system configured to selectively operate a first vehicle sub-system,wherein the first control system includes a steering system that generates a command to operate the first vehicle sub-system;
a second control system configured to selectively operate a second vehicle sub-system comprising an actuator;
wherein said second control system includes a vehicle stability enhancement system; and
a controller configured to;
determine a priority between said first control system and said second control system, and whereby invokes said first control system, andmonitor a first parameter associated with said first vehicle sub-system and a second parameter associated with said second vehicle sub-system, said controller being configured to control said first and second parameters by selectively invoking operation of said second control system only when said first parameter exceeds a first threshold and said second parameter exceeds a second upper threshold.

Abstract
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.

14. A vehicle having an integrated vehicle control system, comprising:
-
a first control system configured to selectively and independently operate an active steering system; a second control system configured to selectively and independently operate a vehicle drivetrain comprising a brake actuator; and a controller configured to; determine a priority between said first control system and said second control system, and whereby invokes said first control system, and monitor a first parameter associated with said active steering system, said controller being configured to selectively invoke operation of said second control system when said first parameter exceeds a threshold, wherein said controller is configured to monitor a second parameter associated with said vehicle drivetrain and wherein said controller is configured to selectively invoke operation of said second control system when said second parameter exceeds an upper threshold. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
