  • 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.

  • Method for monitoring an auxiliary pump for a hybrid powertrain
    Patent number: 8068966
    Abstract: A powertrain system includes a hybrid transmission coupled to an engine and an auxiliary hydraulic pump.

  • Electric variable transmission for hybrid electric vehicles with three forward modes, one reverse mode, and five fixed gears
    Patent number: 8066609
    Abstract: The present disclosure provides a power split transmission with three forward Electric Variable Transmission (EVT) modes, one reverse EVT mode, and five fixed gears for use in hybrid electrical vehicles (HEV). The present disclosure utilizes two electric motors (“E-motors”), an engine, three planetary gear sets, three selectively engageable clutches, and two selectively engageable brakes. The clutches and brakes are engaged in different combinations to engage the different gears and EVT modes. In the five fixed gears, power is transmitted only on the mechanical path for the highest transmission efficiency. In the EVT modes, a part of the power is transmitted electrically. Additionally, the present disclosure includes a front E-motor designed allowing scalable E-motors and a modular transmission design and a center E-motor design.

  • 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.

  • Device for removing nitrogen oxides from internal combustion engine waste gas and method for dosing an aggregate of internal combustion engine waste gas
    Patent number: 8061122
    Abstract: In a device and a method for removing nitrogen oxides from the exhaust of an internal combustion engine which is operated predominantly with an excess of air, the internal combustion engine is assigned an exhaust system having a nitrogen oxide reduction catalytic converter which comprises two catalytic converter parts, whose reducing agent filling levels can be determined. Metering of a reducing-agent-containing additive into the exhaust gas of the internal combustion engine takes place as a function of the reducing agent filling level of the first catalytic converter part and/or of the second catalytic converter part.

  • Method and control device for adjusting a rotational speed of a shaft of a gear change transmission
    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.

    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.
