  • Motor Vehicle Having a System for Feeding Fluid into Another Medium, Particularly for Feeding a Reducing Agent into the Exhaust Gas of an Internal Combustion Engine
    Publication number: 20110179772
    Abstract: In a system for feeding fluid into an exhaust gas after-treatment system, during operation fluid is fed via a feed line of the dispensing unit from a main container and is partially returned via a return line to the main container. A diaphragm pressure container is provided on the feed line downstream of a pump and a non-return valve toward the dispensing unit. During operation of the pump, the diaphragm pressure container is filled with fluid. The diaphragm pressure container is emptied as soon as the pump stops operating. In this way, the dispensing unit is cooled even after the operation of the system has ended, thereby protecting electronic components of the same from overheating.

  • Method and device for recognizing tiredness
    Patent number: 7978086
    Abstract: In a method and in a device for detecting when the driver of a motor vehicle becomes tired, the tiredness is determined as a function of a detected steering inactivity phase and a subsequent steering action. In this context, the steering inactivity phase is logically combined with the steering action, and the logic combination is stored at various times. The logic combination is stored with an assigned weighting factor, and the weighting factor is determined as a function of a classification of a steering situation.

  • BRAKE DISK HAVING A BRAKE DISK POT
    Publication number: 20110162926
    Abstract: The invention relates to a brake disc having a brake disc pot (42) and a friction ring (10) which is positively connected to the brake disc pot via toothing (50). The friction ring (10) comprises two friction ring halves (12, 14), wherein the toothing extends across only one of the friction ring halves. In this manner it is possible to mount through-passages (30) axially adjacent to the toothing running around the friction ring half on the interior circumference of the friction ring, said passages connecting the interior circumference of the friction ring to an interior ventilation arrangement of the friction ring. In this manner both a good force transmission and a stable positive connection is ensured between the friction ring and the brake disc pot, as is an efficient cooling by means of an interior ventilation of the friction ring.

  • Method and device for automatically switching to main beam
    Patent number: 7973484
    Abstract: A main beam switching arrangement for a road vehicle has a lighting device switchable over main beam and dipped headlamps. A sensor device determines at least one ambient parameter, and a control unit with an activatable and deactivatable automatic function automatically switches over the lighting device as a function of the ambient parameter. An operator control unit generates switchover signals by an operator to manually bring about switching over the lighting device with priority. In each case, at least one change of state of the automatic function can be brought about by a first switchover signal for switching on continuous operation of the main beam that is not occurring at the time of signal generation. By way of a second switchover signal, continuous operation of the main beam, which is occurring at the time of signal generation, is switched off.
