A method and system for making available an improved phase signal of a phase sensor on a camshaft of an internal combustion engine immediately after switching on the phase sensor and/or the internal combustion engine are provided. In this context, the phase sensor scans the angle marks of a signal-generating wheel that is connected to the camshaft in a torsionally fixed manner. 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.

Method and system for making available an improved phase signal of a phase sensor on a camshaft of an internal combustion engine

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.

Diagnostic method for a sensor

A measuring device for contactless detection of a ferromagnetic object, comprising at least one magnet; a magnetic field-sensitive element arranged so that an air gap is provided between the magnetic field-sensitive element and the ferromagnetic object; and a soft-magnetic component located between magnet and the magnetic field-sensitive element on a face of the magnet which points in a direction of the ferromagnetic object to be detected, said soft-magnetic component being formed as a cap-shaped element that has a recess that is open in a direction away from said magnetic field-sensitive element to house the magnet and an opening that is open in a direction of the magnetic field-sensitive element, to house the magnet and opening that is open in a direction of the magnetic field-sensitive element, the soft-magnetic component having a first side wall defining said recess and also having a portion which forms a second side wall defining said opening, said first side wall and said second side wall being in alignment with one another.
