The circuit controls powertrain, drivetrain, vehicle suspension and accessory components of an automotive vehicle to programmatically provide different drive and handling performance using a portable personal electronic telecommunication device having memory and a processor. The circuit includes a protocol converter circuit coupled to receive electric power from an electrical power system of the automotive vehicle, and has at least one port to electrically couple to at least one actuator that supplies control to the controlled component of the automotive vehicle. The protocol converter circuit provides a communication channel by which communication is established with a portable personal electronic telecommunication device. An executable program stored in the memory circuit and operated by the processor of the portable personal electronic telecommunication device supplies control signals via the protocol converter circuit to the one or more actuators, thereby programmatically providing different vehicle drive and handling performances.

A driveline component with a housing, a pinion mounted in the housing for rotation about a first axis, a ring gear and a pair of output members. The ring gear is meshed with the pinion and is rotatable about a second axis. The ring gear is supported for rotation relative to the housing by a pair of tapered roller bearings that are disposed along the second axis on a common lateral side of the ring gear. The output members are drivingly coupled to the ring gear.

A vehicle driveline that includes a differential assembly, a two-speed transmission, a power take-off unit, a range sleeve, a mode sleeve and an input shaft. The range sleeve is non-rotatably but axially slidably coupled to the input shaft. The range sleeve provides rotary power to the two-speed transmission and is movable into different positions to control the gear ratio in which the two-speed transmission operates. The two-speed transmission outputs rotary power to the differential assembly. The mode sleeve is selectively movable into a position where it transmits rotary power between the range sleeve and a PTU input of the power-take off unit. Movement of the range and mode sleeves can be coordinated to provide a two-wheel drive high speed mode, a four-wheel drive high speed mode and a four-wheel drive low speed mode.

The present teachings provide for a power transfer device and method of forming a power transfer device that includes a unitarily formed transfer member and a support member. The transfer member can be supported within a housing for rotation about an input member and can be coupled to the input member to receive rotational power therefrom. A ring gear defined by the transfer member can meshingly engage with a pinion gear. The support member can be disposed concentrically about the input member and be rotatable about a first axis relative to the housing. The support member can have a first end and a second end. The first end of the support member can be supported for rotation relative to the housing by a support bearing. The second end of the support member can be received within a bore defined by the transfer member and fixedly coupled thereto for common rotation.

A damped propshaft assembly with a hollow shaft and a tuned damper, which is received in the hollow shaft and includes a liner and a damping member. The liners mass and stiffness are tuned to attenuate one or more of a bending mode vibration and a torsion mode vibration that occurs at a first predetermined frequency. The liner is not configured to substantially damp shell mode vibration that occurs at a frequency that is not equal to the first predetermined frequency. The damping member is coupled to the liner and is configured to primarily attenuate shell mode vibration in the hollow shaft at one or more desired frequencies. The tuned damper attenuates the at least one of the bending moment vibration and the torsion mode vibration at the first predetermined frequency and also attenuates shell mode vibration. A method for forming a damped propshaft assembly is also provided.
