- generating a roll attitude angle of a body frame with respect to an intermediate axis system to determine one of a plurality of vehicle dynamic variables;
generating a pitch attitude angle of said body frame with respect to said intermediate axis system to determine one of a plurality of vehicle dynamic variables;
generating an x velocity component of said body frame with respect to said intermediate axis system to determine one of a plurality of vehicle dynamic variables;
generating a y velocity component of said body frame with respect to said intermediate axis system to determine one of a plurality of vehicle dynamic variables;
generating a z velocity component of said body frame with respect to said intermediate axis system to determine one of a plurality of vehicle dynamic variables;
transforming the plurality of vehicle dynamic variables from a sensor frame to a body frame as a function of vehicle dynamic sensor misalignments;
generating a vehicle safety device control signal in response to said transformed dynamic variables; and
controlling the vehicle safety device using the vehicle safety device control signal.

Abstract
A vehicle control system includes a housed sensor cluster generating a plurality of signals. An integrated controller includes a sensor signal compensation unit and a kinematics unit, wherein the sensor signal compensation unit receives at least one of the plurality of signals and compensates for an offset within the signal and generates a compensated signal as a function thereof. The integrated controller further generates a kinematics signal including a sensor frame with respect to an intermediate axis system as a function of the compensated signal and generates a vehicle frame signal as a function of the kinematics signal. A dynamic system controller receives the vehicle frame signal and generates a dynamic control signal in response thereto. A safety device controller receives the dynamic control signal and further generates a safety device signal in response thereto.
