Abstract: A method for maintaining a predetermined voltage in a battery-supported vehicle electrical system during the operation of an electrical starter includes steps of operating the electrical starter on the vehicle electrical system during a first time phase in series with a limiting resistor, in order to limit the current flowing through the starter, and operating the electrical starter on the vehicle electrical system during a second time phase with a reduced limiting resistance, in order to increase a power converted by the starter. A transition from the first time phase to the second time phase is controlled on the basis of electrical parameters sampled during the first time phase at the limiting resistor.

Abstract: A magnetic sensor arrangement (1), having magnetically sensitive sensor elements (7, 8) whose electrical properties are changeable as a function of a magnetic field that a moving, passive transmitter element (11) is able to influence. The magnetic sensor arrangement (1) has two sensor elements (7, 8) in a gradiometer arrangement that are each respectively associated with one of two magnetic regions (4, 5) of a permanent magnet embodied in the form of a gap magnet (2; 20; 23), which regions are spaced apart from each other by a predetermined distance (sa). The regions (4, 5) and the gap magnet (2; 20; 23)—in terms of the for example wedge-shaped embodiment, the dimensions (h, b, t), the gap width (sa), the gap depth (st), and their positions in relation to the sensor elements (7, 8)—are situated so as to minimize the offset of the output signal of the sensor elements (7, 8) in the gradiometer arrangement.

In addition, a crankshaft sensor scans the angle marks of a signal-generating wheel that is connected to the crankshaft in a torsionally fixed manner.

Abstract: The method and circuit arrangement both minimize stray electromagnetic interference in an electronic circuit, in which symmetric measurement signals are evaluated. Both inputs (InP, InM) of an evaluation circuit (2) are provided with a bank of switchable capacitors (Cz) individually or in groups, which are connectable with the respective inputs. A predetermined interference signal is applied to the respective inputs (InP, InM) and individual ones or groups of the switchable capacitors (Cz) are selectively connected with the inputs (InP, InM) so that a maximum suppression of the predetermined interference signal can take place. Data regarding the capacitance values selected during the suppression of the predetermined interference signal is stored in the memory (3?) of a switching controller (3) during selective switching so that the same adjustment occurs automatically during subsequent operation cycles of the circuit arrangement.

Abstract: In a method for diagnosis of a sensor in a motor vehicle having an internal combustion engine, during operation of the motor vehicle, an output signal of the sensor is monitored for whether a maximum value of the output signal undershoots a first threshold value and/or a minimum value of the output signal overshoots a second threshold value. In that case a signal is forwarded to a controller that signals to the controller that the sensor, upon restarting of the motor vehicle, might be furnishing incorrect data.

Abstract: A method for detecting the motion of an element relative to a sensor apparatus is proposed, in which a detection of the direction of motion is performed. As a function of the direction of motion, a measurement signal is increased or decreased at predetermined measurement intervals, and only if a predetermined threshold value is exceeded is a direction-of-motion signal generated. Preferably, by means of a counting logic circuit (6), a counter is increased by a binary amount In one direction (2) and the counter (6) is decreased by a binary amount in the respective other direction (3). Upon a detection of measurement signals which as a result of being increased or decreased in a measurement interval do not lead to exceeding of the predetermined amount of the threshold value, vibration of the element is assumed.
