  • Method for electric power boosting in a powertrain system
    Patent number: 8067908
    Abstract: A powertrain system is operative to transfer power between an input member and a plurality of power actuators and an output member to generate an output torque. The power actuators are connected to an energy storage device. A method for controlling the powertrain system includes monitoring operating conditions of the powertrain system, determining an electric power limit for output power of the energy storage device, selectively enabling electric power boost based upon the operating conditions of the powertrain system, and increasing the electric power limit when electric power boost is enabled.

  • Restraining device for an occupant of a vehicle
    Patent number: 8068956
    Abstract: In a restraining device for an occupant of a vehicle, having a belt that can be drawn out or retracted by a lockable retractor, and a reversible seat-belt tightener, in the case of an impending but still avoidable first event the reversible seat-belt tightener automatically exerts and maintains a first tightening force on the belt and/or reduces the first tightening force if the first event is no longer impending. In the case of an impending, no longer avoidable second event, automatically exerts a second tightening force on the belt which is greater than the first tightening force. The first tightening force and the second tightening force acting constantly in the retracting direction.

    Patent number: 8062181
    Abstract: In a method and control device for adjusting a rotational speed of a shaft of a gear change transmission of a motor vehicle, a torque required for the acceleration of the transmission and derived from a drive motor is transmitted by means of an automated clutch and using the torque the rotational speed of the shaft is precisely and rapidly adjusted to a range around a target rotational speed by defining a desired value for a position of the clutch on a rotational speed difference between a measured rotational speed of the shaft and a target rotational speed so that the gear can then rapidly be changed.

  • Method for controlling power flow within a powertrain system
    Patent number: 8060267
    Abstract: A method for operating a powertrain system includes monitoring a state of charge of an energy storage device and determining an effective state of charge based upon the monitored state of charge of the energy storage device and a range of available power from the energy storage device. A preferred output power to an output member is determined. A preferred charge state for operating the powertrain is concurrently selected with operating an engine in one of a cylinder deactivation state and an all-cylinder state based upon the effective state of charge and the preferred output power to the output member.

  • Device for guiding the movement of a wind deflector
    Patent number: 8056968
    Abstract: A device is provided for guiding a movement of a bar-type wind deflector in relation to a roof frame in a region between a position of use and a position of non-use, especially on a cabriolet. At least one pair of rotary levers is provided on the wind deflector. The rotary levers are mounted on the wind deflector at a first rotary lever end such that they can rotate about a first rotational axis, and on the roof frame at a second rotary lever end such that they can rotate about a second rotational axis, the rotational axes being parallel to each other. The rotary levers of each pair are staggered in relation to each other at least in the direction of a normal of one of the rotational axes. The rotational axes of each pair form the vertexes of a parallelogram.

  • Selectively removable side fairing for a vehicle
    Patent number: 8056959
    Abstract: A detachable side fairing for a vehicle in one form comprises a panel body that can include steps. An access opening is defined by the panel body and is opened and closed by a door, such as the riser of a step, to allow access to the rear of the panel. A latch actuator can be accessed through the access opening for use in operating a latch to allow movement of the panel body away from the vehicle. The latch actuator can comprise first and second actuators comprising respective first and second elongated handles that each actuates an associated latch to release the panel body. The handles can be configured to prevent closing of the door when the actuators have not been moved to a position that completes the latching of the panel body to the vehicle.
