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 operating a hydraulic safety system 38 includes determining a relative roll angle, determining a relative a slip angle, determining a yaw rate and determining a pressure build rate for the hydraulic safety system 38 in response to a relative roll angle, the yaw rate, slip angle, and yaw rate. The method further includes determining a precharge pressure level in response to the relative roll rate, the slip angle and the yaw rate and controlling the safety system 38 in response to the precharge pressure level.
