A steering wheel () for a motor vehicle includes a steering wheel module () supporting electrical/electronic subassemblies (). The steering wheel module is inserted from a front side of the steering wheel into a center of the steering wheel in order to be attached to the steering wheel. A lower end of the steering wheel module forms a torsion module () of a torque detection device for a steering power-assist system. The torsion module is operable to receive and be attached to a steering spindle () of a steering column on the back side of the steering wheel in order to attach the steering wheel to the steering spindle when the steering wheel module is attached to the steering wheel.

A method for correcting a characteristic curve having values corresponding to displacement between a magnetic sensor element and a magnetic ruler of a sensor within a displacement range includes determining whether the characteristic curve has a jump discontinuity by comparing a first value at a first range end to a second value at a second range end and by comparing values between the range ends. Upon determining that the characteristic curve has a jump discontinuity, the method further includes determining the magnitude of the jump discontinuity, defining a decision threshold lying between the first and second values, identifying the values within the range which are lower than the decision threshold, and offsetting the identified values by the magnitude of the jump discontinuity such that the characteristic curve is corrected to eliminate the jump discontinuity, whereby subsequent measurements made by the MR sensor take into account the jump discontinuity magnitude offset.

A motor vehicle optoelectronic monitoring device includes a sensor, imaging systems, a shutter, and a controller. Each sensor element outputs a sensor element signal based on the intensity of a light signal received by the sensor element. Each imaging system is associated with a sensor region and illuminates an object to monitor the object. Two sensor regions associated with two respective imaging systems partially overlap one another. Each imaging system illuminates the sensor elements of the associated sensor region with a light signal indicative of the object being monitored. The controller controls the shutter unit to selectively enable and disable illumination of the sensor by the imaging systems. The controller processes the sensor element electric signals output by the sensor elements in response to illumination by an imaging system to determine conditions of the object being monitored by the imaging system.

An electric circuit arrangement and method for checking intactness of both a photodiode array and an electrical connection between an array output and a microprocessor input. The array output has a high resistance when the array is inactive and intact. In case of array error, the array output is connected via in each case a defined internal resistance to ground and supply voltages. The circuit arrangement enables at any time an assessment of the status of the connection and, if the connection is intact, enables an assessment of array intactness. This is achieved by connecting the array output via a first test resistor arranged in the spatial vicinity of the array to the ground voltage and by connecting the microprocessor input via a second test resistor arranged in the spatial vicinity of the microprocessor to a microprocessor port output which can be connected either to the ground or supply voltages.
