1. A system for controlling a safety system of an automotive vehicle comprising:
- a first controller generating a first control signal;
a second controller generating a second control signal;
an arbitration module coupled to the first controller and the second controller, said arbitration module choosing the higher of the first control signal and the second control signal to a final control signal; and
the safety system coupled to the arbitration module, said safety system operated corresponding to the final control signal.

Abstract
A method of controlling a safety system 38 of a vehicle 10 include determining a roll rate, determining a first control pressure in response to roll rate, determining a roll angle, and determining a second control pressure in response to the roll angle. The method further includes determining a final control pressure in response to the first control pressure and the second control pressure and controlling the safety system in response to the final control pressure.
