  • Loudspeaker system for motor vehicles utilizing cavities formed by supporting structures
    Patent number: 8044413
    Abstract: In order to produce a powerful bass, bass boxes require a relatively large installation volume, for which insufficient space is frequently available in the interior of a motor vehicle, in particular in a passenger motor vehicle. When drivers and front-seat passengers require the sound installation to have a powerful bass, a bass box requires a volume in the order of magnitude of at least 10 to 15 liters. In order to restrict the physical space which is required for this purpose in the vehicle interior, the active sound transducer of the loudspeaker system is acoustically coupled on its rear face to a resonant area which is formed at least in parts by the cavity within a supporting structure of the vehicle.

  • Method and device for preventively actuating a vehicle occupant protection system
    Patent number: 8036794
    Abstract: In a method and a device for preventively actuating a vehicle occupant protection means in a vehicle having a vehicle movement dynamics control system, the vehicle occupant protection elements can be activated before a collision time and thus placed in an operative position. An evaluation variable relating to a state of “oversteering” is monitored, and when the state of “oversteering” is identified the vehicle occupant protection elements are activated. The evaluation variable for monitoring the state of “oversteering” is determined by using a manipulated variable of the vehicle movement dynamics control system.

  • Method and computer program for identification of inattentiveness by the driver of a vehicle
    Patent number: 8035496
    Abstract: A method and a computer program for identifying when the driver of a vehicle, in particular a motor vehicle, is not paying attention. In order to make it possible to make a more reliable statement on the presence of any inattentiveness by the driver, the method observes a steering action following a steering quiescent phase, in addition to detecting the steering quiescent phase. The extent of the steering quiescent phase and of the steering action found are logically linked to one another, and the result of this logical operation is then used as a measure for the severity of the inattentiveness of the driver.

  • Driver Assistance System and Method for Supporting the Driver of a Vehicle in Maintaining a Traffic Lane Limited by Traffic Lane Markings
    Publication number: 20110234390
    Abstract: In a method and apparatus for assisting the driver of a vehicle in maintaining a traffic lane limited by traffic lane markings, the traffic lane markings and the position of the vehicle in the traffic lane are detected. Upon an actual or impending change of traffic lanes a lane change warning is output to the driver of the vehicle in a first step, and a course correcting actuating intervention counteracting the lane change is carried out in a second step. The actuating intervention is carried out only if the change of traffic lanes is impermissible due to the type of traffic lane marking to be crossed during the traffic lane change, or if the lane change is not possible without danger due to collision-endangering objects present on the side of the traffic lane.
