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.
