Abstract: A structural joint configuration is used in an automotive body structure in which a transverse roof cross member has a convoluted formed shape that must be connected to the longitudinally extending tubular roof side rail. A two-piece clam shell bracket forms the joint apparatus. A lower piece formed in a shape to mate to and receive the transverse roof cross member is welded to the underside of the tubular roof side rail while projecting a formed receiver to engage the transverse roof cross member. An upper piece clamps over top of the transverse roof cross member and is welded to the top portion of the tubular roof side rail. The joint apparatus can be secured to the transverse roof cross member and to the roof side rail by either welding or by adhesives to provide a reinforcement at the joint between the two structural members.

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.

Abstract: A support rail for a vehicle has an A-pillar portion and a roof rail portion. The roof rail and A-pillar are formed with a tubular body portion and longitudinally extending support flanges. The support flanges are formed by pinching the blank during the hydroforming process to provide a double thickness flange. A windshield support flange, roof support flange and door opening flange are formed to extend outwardly from the tubular body portion. Front and rear tube connectors include blind openings or notches to facilitate welding.

Abstract: A joint assembly for joining a tubular B-pillar to a tubular roof rail. The joint assembly includes an inner bracket plate and an outer bracket plate that are welded to each other around the roof rail and B-pillar. The outer bracket plate extends across the B-pillar, over the roof rail, and laterally inwardly from the roof rail to provide an attachment surface for a roof support bow.

Abstract: A yaw stability control system (18) is enhanced to include roll stability control function for an automotive vehicle and includes a plurality of sensors (28–39) sensing the dynamic conditions of the vehicle. The sensors may include a speed sensor (20), a lateral acceleration sensor (32), a yaw rate sensor (28) and a longitudinal acceleration sensor (36). The controller (26) is coupled to the speed sensor (20), the lateral acceleration sensor (32), the yaw rate sensor (28) and a longitudinal acceleration sensor (36). The controller (26) generates both a yaw stability feedback control signal and a roll stability feedback control signal. The priority of achieving yaw stability control or roll stability control is determined through priority determination logic. If a potential rollover event is detected, the roll stability control will take the priority.
