System for determining an amount of control for operating a rollover control system

A system for controlling a safety system of an automotive vehicle has a first controller (76) generating a first control signal, a second controller (78) generating a second control signal and an arbitration module (80) coupled to the first controller (76) and the second controller (78). The arbitration module (80) chooses the higher of the first control signal and the second control signal to generate a final control signal. The safety system is coupled to the arbitration module. The safety system is operated in response to the final control signal. One method of operating a hydraulic safety system includes determining a relative roll angle, determining a relative a slip angle, determining a yaw rate and determining a pressure build rate and precharge pressure level for the hydraulic safety system in response to a relative roll angle, the yaw rate, slip angle, and yaw rate.
