A redundant data connection plays an important role for automated driving functions. In order to evaluate the advantages of such a system, VW Commercial Vehicles commissioned Desay SV to develop a telematics and measurement concept and test it in practice.
Data coverage plays an important role in the development of telematic units for vehicles with automated driving functions, especially at levels 4 and 5 [1, 2]. The redundancy of the system is required by legislative demands and ensures a comprehensive solution. For example, the German legislator has stipulated that motor vehicles with Autonomous Driving (AD) functions must be able to “ensure sufficiently stable radio connections that are protected against unauthorized interference, in particular to the technical supervisor, and independently put the motor vehicle in a state that minimizes risk if this radio connection is interrupted or accessed without authorization” [3, 4]. To evaluate the overall reliability of the system, the measurement system and further data post-processing are very important.
