Vehicle Testing

Continous and automated data during field tests

Development cycles are becoming ever shorter and the requirements for product quality are becoming ever higher, and this holds true not only in the automotive industry.

In order to master these challenges, it is essential to conduct extensive series of measurements in the course of practical field tests. The interaction of controller software with the mechanical, hydraulic and electrical components is becoming increasingly more complex. With regard to agricultural machines, this is especially relevant for tractors, self-propelled harvesters and attached implements.One may well ask: what are the requirements for such autonomous data loggers, which are used in parallel to development on the one hand, and directly in customers’ vehicles, on the other?


For the purpose of long-term studies, one would need particularly robust systems, which are capable of withstanding extreme environmental conditions such as heat, cold, spray water and shock. The requirements for data loggers are just as stringent with regard to online billing and storage. Thus, machine data have to be recorded continuously and/or in an event-driven manner and synchronised with GPS coordinates, video sequences, analogue or digital measurement channels (temperatures, pressures, paths, forces, vibrations, etc.). Afterwards, the collected data is automatically transmitted via the mobile radio network and provided to the test engineer via a web front end. Even with the field test still in progress, the test engineer is already able to conduct an automated evaluation of the initial measurement data and apply the acquired insights to the implementation of the test. The requirements are presented by using the self-propelled sugar beet harvester Maxtron 620 of the company Grimme Landmaschinenfabrik GmbH & Co. KG as an example.
