Abstract
Current vehicle concepts necessitate the multiple measurement of several variables required by separate electronic systems in the motor vehicle. There is the need to make sensors bus capable by the incorporation of electronic components in new definition concepts, in other words to make them multiply usable. Such bus concepts are at the present time taking concrete shape.
The step of introducing electronics - especially digital - to the measuring point may simultaneously be used to considerably improve utilization of the information content of sensor structures using means of indivdual, digital correction to a greater level than has until now been technically possible. There remains the demand for high stability and reproducibility of the sensor properties over time.
These signal preprocessing and information condensation processes on the spot also satisfy the need to relieve the central control units. According to manufacturer information, improved adaptation of the operational specification of electronic circuitry for such concepts will be possible in the near future.
The development of such “smart” sensors with electronics on the spot is in its infancy. The advantages of these new sensor structures, illustrated by several interesting cases, as well as general aspects, are described in detail below.
