Abstract
A vehicle includes a control system that is used to control a vehicle system. The control system determines a roll condition in response to a yaw rate sensor and a pitch rate sensor without having to use a roll rate sensor. A relative roll angle, relative pitch angle, global roll angle, and global pitch angle may also be determined. A safety system may be controlled in response to the roll condition, roll angle, or the pitch angles individually or in combination.
