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.

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.
