Abstract: A press-in contact and a press-in tool for connecting an electronic component to a printed circuit board, the press-in contact of the electronic component being pressed into a contact opening of the printed circuit board by the press-in tool. Also a method for producing a press-in contact. The press-in contact includes at least one guide region which can be received in a guide contour of the press-in tool in a position-fixing manner. The maximum length of the guide region is a multiple of the maximum width or is substantially equal to or only slightly shorter than the maximum width and/or the guide region is highly rigid in the press-in direction (z direction) and flexible in the other directions (x/y directions). The method according to the invention is characterized in that contiguous, interlinked contours of the press-in contacts, which contours are produced as a ribbon or band, are supplied to a separating station and are separated at predetermined separation points into individual press-in contacts.

Abstract: A method for steering a motor vehicle in a collision avoidance maneuver ahead of an object in the front or lateral surroundings of the motor vehicle. It is arranged that a linear control method is employed, in which case one controller output signal (?LLM1; . . . ; ?LLMN) each is determined in at least two linear controller modules depending on a deviation (e) between an actual position of the motor vehicle and a nominal position that is predetermined due to the avoiding path. The controller output signals (?LLM1; . . . ; ?LLMN) are weighted with respectively one weighting factor (?1; . . . ; ?N) that is established depending on the vehicle speed (v), and a steering angle of steerable wheels of the motor vehicle is established based on an arbitration of the weighted controller output signals. Furthermore, a device which is suitable to implement the method is provided.

Abstract: The present invention relates to a hydraulic aggregate for a slip-controlled brake system which includes noise damping chambers integrated in a pump bore, wherein there is a hydraulic connection between the brake pressure generator ports and the noise damping chambers by means of pressure fluid channels that open radially or tangentially into the pump bore and are connected to the valve accommodating bores of the first valve row of an accommodating member in which the inlet valves are received.

Abstract: The present invention discloses a method for brake pressure adjustment of a wheel brake comprising the following steps: determining a preliminary nominal pressure gradient in a brake control, determining actuating signals for a hydraulic pump and/or at least one hydraulic valve for the adjustment of the nominal pressure gradient, determining the actual pressure by way of a pressure model, determining the slip of a driven wheel, comparing the actual pressure with a first threshold value that is lower than the maximum possible brake pressure, and comparing the wheel slip, if the wheel slip is a traction slip, with a second threshold value, wherein, if the actual pressure and the wheel slip exceed the respective threshold values, the preliminary nominal pressure gradient is raised. The present invention also relates to a corresponding device.

Abstract: The present invention relates to a circuit configuration with an A/D converter, especially for applications that are critical in terms of safety, which is especially characterized by a ramp signal generator for generating a ramp voltage that is delivered to the input of the A/D converter, and a test circuit for activating a test cycle which comprises a first run of the ramp, by which a reference measurement of the ramp signal generator is carried out for compensating component tolerances, and comprises a second run of the ramp where an error signal is output when the value that is calculated for a transmission characteristic of the A/D converter lies outside a predetermined tolerance range of the measured value of the transmission characteristic.

Abstract: The present invention relates to a method of improving the control , behavior of an electronically regulated and/or controlled driving stability control system, wherein input quantities for the control are derived from the rotational behavior of the wheels and wherein in situations which are critical for driving stability, the driving stability is increased by braking pressure introduction and/or braking pressure modulation. In order to obviate the need for a precharging pump, the present invention proposes that criteria for evaluation of the driving situation and for the early detection of a driving situation inhering an increased risk are derived from the rotational behavior of the wheels, and that the commencement of driving stability control is prepared upon detection of a driving situation inhering an increased risk. A brake system for implementing the method is also an object of the present invention.

Abstract: The present invention relates to a disc brake with hydraulically operable brake pads and a mechanical actuating which includes an actuating shaft that is rotatably and sealedly mounted in a bore of a brake housing and acts upon at least one of the brake pads. The present invention focuses on that at least in the area of a shaft duct, a sealing element is provided which is fixed to the actuating shaft so as to rotate along with it and cooperates with at least one associated sealing element and/or mating sealing surfaces in a radial direction. The sealing element bridges a portion of the actuating shaft which is different from the shape of a circle.
