Embodiment Construction

[0053] figure 1 An exemplary embodiment of the invention is shown for a transmitter device 100 for transmitting a sensor signal 105 to a physical variable detected by a sensor (not shown). Transmitting device 100 includes the following features: input interface 110 for receiving sensor signal 105 ; signal generator 120 for generating comparison signal 125 ; data processing unit 130 ; and output interface 140 . Data processing unit 130 is designed to process sensor signal 105 and comparison signal 125 and combine them (for example via a multiplexer) to form a conditioned sensor signal 135 . Output interface 140 can be coupled to a signal path 150 in order to emit conditioned sensor signal 135 on this signal path 150 . In order for a receiver (receiving device) to be able to detect an incorrect sensor signal or an incorrect transmission by means of comparison signal 125 , comparison signal 125 changes over time in a predetermined manner over a value range.

Abstract

The invention relates to a transmission device (100) for transmitting a sensor signal (105) relating to a physical variable, comprising the following characteristics: an input interface (110) for entering the sensor signal (105); a signal generator (120) for generating a comparison signal (125); a data processing unit (130); and an output interface (140). The data processing unit (130) is designed to process the sensor signal (105) and the comparison signal (125), and to combine same to form a modified sensor signal (135). The output interface (140) couples to a signal path (150) in order to emit the modified sensor signal (135). The comparison signal (125) changes over time in a predetermined manner over a range of values, in order to permit a receiver to detect an erroneous sensor signal or an erroneous transmission by means of the comparison signal (125).

Description

technical field [0001] The invention relates to a transmitting device and a receiving device for sending and receiving sensor signals, and in particular to a device and a method which ensure a check of the transmission of sensor signals, in particular for harsh applications in vehicles. Strict use occasions. Background technique [0002] More and more functions in vehicles are controlled and monitored electronically. Increasingly, this control also includes safety-relevant components of the vehicle, for which error situations cannot be tolerated. This concerns, for example, the steering in vehicles or the detection of pedal positions such as the brake pedal, where high demands are placed on the electronic control. [0003] Here, in particular, it must be ensured that the measured values ​​(i) are not spurious and (ii) are real-time. In the event of an error anywhere in the measuring chain, it is important that this error be recognized reliably and quickly. [0004] Howev...
