Abstract: A longitudinal frame for the chassis structure of a motor vehicle is provided. The frame includes at least two longitudinal sections, which are joined together to form a shared longitudinal structure by having the longitudinal sections at least partially overlap each other in an overlap region. One of the longitudinal sections of the frame has a side panel, which in the overlap region exhibits a connecting section for attachment to a floor panel, and the other longitudinal section exhibits a counter-panel in the overlap region that at least partially abuts against the side panel. The abutment of the counter-panel against the side panel remains outside of the connecting section. The frame includes at least one longitudinal structure, and the longitudinal structure and at least one of the longitudinal sections together extend over a longitudinal section of the longitudinal frame.

Abstract: A hydraulic control system and method for controlling a dual clutch transmission includes a plurality of pressure and flow control devices and logic valve assemblies in fluid communication with a plurality of clutch actuators and with a plurality of synchronizer actuators. The clutch actuators are operable to actuate a plurality of torque transmitting devices and the synchronizer actuators are operable to actuate a plurality of synchronizer assemblies. Selective activation of combinations of the pressure control solenoids and the flow control solenoids allows for a pressurized fluid to activate at least one of the clutch actuators and synchronizer actuators in order to shift the transmission into a desired gear ratio.
