  • Patent number: 6215415
    Abstract: A parking aid for a motor vehicle, which measures the distance between an object and the motor vehicle in a contactless manner and has a plurality of sensors which are arranged on the motor vehicle, each sensor emitting a signal and receiving the signal reflected from an object located in the direction of the beam, and an evaluation device connected to the sensors determining the distance between the object and the motor vehicle from the signals received. The outlay for electrically synchronizing the sensors is reduced and which nevertheless allows reliable detection of the actual object for accurate measurement of the distance, has three sensors which are arranged directly next to one another to provide approximate coverage of the same detection area, whereby the main beam of each sensor having approximately the same beam angle.

  • Patent number: 6209594
    Abstract: In the case of a filling pipe for a fuel tank a branching element is arranged in a section of the filling pipe. The flow of the inflowing fuel preferably runs along an outer wall of the filling pipe, so that a subflow is in each case conducted directly to the antisurge tower through a lower cross-sectional area. Larger volume flows, which completely fill the cross section, pass for the most part directly into the fuel tank. By this means, a sufficient basic supply of the antisurge tower is ensured irrespective of the volume flow produced during filling.

  • Patent number: 6209314
    Abstract: A method for regulating the fuel/air ratio of an internal combustion engine, the output signal from a first lamba probe, which is arranged in the exhaust duct of the internal combustion engine upstream of a catalyst, being supplied to a controller, and the controller emitting a manipulated variable for the fuel/air ratio, and there being supplied to the controller a correcting signal which is obtained from the output signal from a second lambda probe located downstream of the catalyst. In order to allow accurate and adapatable regulation which further improves the fuel/air ratio with the effect of a reduction in the exhaust gas emission, the correcting signal is weighted as a function of the period of the output signal from the first lambda probe.

  • Patent number: 6202811
    Abstract: A clutch for a motor vehicle has a sensor device (7) for detecting the limit of wear of friction linings (6), with an electric switch (11) having an electric conductor (13). The electric conductor (13) is severed by a rotatably mounted switching part (14) when the limit of wear is reached. Before the limit of wear has been reached, the switching part (14) is biased by a blocking part (15) into a position remote from the electric conductor (13). It is possible thereby to determine the limit of wear with particular exactitude.

  • Patent number: 6200214
    Abstract: The invention relates to a tongue connection, in particular for fixing an air vent on a wall in a passenger compartment, on a basic body which is to be arranged in a releasable manner on a border of a wall opening by way of at least two tongues which project from the basic body, the tongues engaging, along the opening border, in the opening and restricting movement of the body in the direction of the opening plane. There is provided on at least one tongue a (radial) protrusion which projects outward in the direction of the opening border, cuts into the opening border when the basic body is installed on the wall, and prevents movement of the basic body in the opening plane by producing a form fit in relation to the opening border.

  • Patent number: 6194797
    Abstract: A multipole electric motor having a plurality of pole laminations (8-11) guided from ends of coils (4, 5) to a permanent magnet (13) of a rotor (14), the pole laminations (8-11) are firstly produced as a coherent sheet-metal part, and is partially injection-coated with a plastic. Subsequently, the pole laminations (8-11) are separated from one another by means of a laser beam, for example. This renders the mounting of the pole laminations (8-11) particularly simple.

  • Patent number: 6186156
    Abstract: In the case of a cleaning device (1) a washer jet (9) is arranged on a piston rod (6) which can be moved by means of an electromotive drive unit (3). A heating element (10), which is connected to a hollow cylinder (2) which is in a fixed location, is situated, in its illustrated position of rest, in the direct vicinity of the washer jet (9) and in this manner makes it possible for the washer jet (9) to be heated thereby preventing it from freezing up when ambient temperatures are critical. No electrical contacts are required on the moveable part of the cleaning device (1) because of the connection of the heating element (10) in a fixed location.

  • Patent number: 6181127
    Abstract: In the case of a method for checking the width of the measuring air gap of a magnetic speed sensor, square-wave output signals are generated from the measurement signals of the sensor by means of at least one prescribable threshold value. The pulse duty factor of the output signals is held within a prescribed range in the case of an acceptable gap width. In the case of amplitudes of the measurement signal outside prescribed limits, the pulse duty factor deviates in a reliably measurable fashion from the prescribed range. A circuit has the means for carrying out this method.
