A sensor integrated circuit comprising a controller and a diagnostic module in communication with the controller. The controller is configured for providing a diagnostic reporting signal being a periodic superposition signal on a sensing output of the sensor integrated circuit and/or on a supply current of the sensor integrated circuit. The periodic superposition signal has periodic pulses with a predetermined fixed pulse duration and a predetermined periodicity. The controller furthermore is configured for altering the predetermined periodicity or predetermined fixed pulse duration of the periodic superposition signal upon a fault detection in the diagnostic module communicated to the controller.

Diagnostic reporting for sensor integrated circuits

A pedal element () with a connecting device () can be moved between an idle position and a full-throttle position of an internal combustion engine at a pedal angle ranging between 0&#xb0; and 5&#xb0; to 30&#xb0;. A signal-generating device is configured in the form of a rotation angle sensor () having at least one integrated circuit (ASIC) with a Hall device. The ASIC with the Hall device and a storage device with an ASIC are connected to a microprocessor. An output switching unit is connected downstream from the microprocessor. The output switching unit emits an pulse-width-modulated signal with selectable frequencies. Other output signals, such as back-to-back signals and switch signals, can be regenerated with the ASIC with the Hall device and the microprocessor.

A Rotation angle sensor includes the following elements:

Rotation angle sensor

For simpler manufacture of a rotation angle sensor and to utilize as much of its angle expansion as possible, the partial stator elements are in the shape of a partial ring split into a large partial stator element () and a small partial stator element () with tangentially arranged spacing openings () located between them. The large partial stator element () covers a range of greater than 180&#xb0; and the small partial stator element a range of less than 180&#xb0; of a circular arc. The large and small stator elements () are at least partially molded into one of the parts made of a magnetically non-conducting material. A magnet element consists of two magnetically bipolar partial magnet segment elements that are essentially of the same length and cover 90&#xb0; or more of a circular arc.

A rotation angle sensor for use in a throttle adjustment device is disclosed, which includes a stator unit having at least two stator part elements positioned relative to each other leaving a spacer recess therebetween; a Hall sensor positioned in the spacer recess; a rotor unit having a magnetic element having a connector element molded into the rotor unit; a plug unit; and a housing unit adapted to partially house the stator unit.

A Hall-effect angular rotation sensor device for a throttle valve unit. The sensor includes a housing unit, a stationary unit, and a moving unit moveable relative to the stationary unit. The stationary and the moving units are at least partially enclosed by the housing unit. The stationary unit includes a first and a second partial ring stator segment that are at least partially retained in the housing unit, leaving a stator distancing gap in which at least one Hall-effect IC switch is positioned. The moving unit includes (a) a partial ring magnet segment that is at least partially distanced from the first and the second partial ring stator segments by an air gap and (b) a third partial ring stator segment positioned behind and opposite the air gap.

In order to enable frequent and easy adjustment of a physical quantity transformed by a sensor into starting values or curves, the following method is applied: a) the modifying unit keeps adjustment data on a temporary memory (,) through the output pin (OUT), and a working unit (,) gives at the output pin (OUT) the starting value and curves as modified; b) once the starting values and curves have found their adjustment position, the adjustment data are stored by the modifying unit (,) in a permanent memory (,).

Device for pin adjusting in sensors

In order to improve the measurement possibilities with regard to a rotating shaft, including the whole angle area (0 to 360&deg;), a rotation angle sensor is mounted that is provided with a radial-bipolar ring-shaped magnetic element (,), three air gaps (,) displaced by an equal angle (&phgr;) being connected with said shaft, and with a stator element (,) of a magnetoconductive material, while a Hall integrated circuit element (,) is inserted in at least two adjacent air gaps (,). The two Hall integrated circuit elements (,) can be connected to an evaluation unit (,) which records a voltage curve of the measured circuit for each circuit element (,), assigns each flow voltage measure to a position angle on the Hall integrated circuit voltage curves, calculates from the position angles assigned to the flow voltage values the actual position angle and gives it as the start signal (A,, A,).
