Application Notes: Vehicles

Vehicles must be able to withstand extreme track conditions, such as potholes, ramps, jumps or curbs. Misuse tests are used to evaluate the safety and performance of components under these conditions. When validating the chassis components and the system behavior of the chassis, it is also a matter of checking the threshold values of the control units for passive safety. Using the imc measurement system CRONOSflex, IDIADA in Spain collected data from the vehicle (CAN-FD, Flexray, in-vehicle sensor signals ...) and from additionally installed sensors (accelerometers, gyroscopes, displacement transducers, force transducers, strain gauges ...) during the tests.

“Fleets Go Green” is a project designed to analyze and evaluate the efficiency of electric vehicles in everyday use with a factory fleet as the test subjects. imc Test & Measurement GmbH is participating in this research project sponsored by the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMU). The research results will form the basis for the decision to convert regular vehicle fleets to electric cars in the future.

For quite some time now, interior noise in cars has been getting quieter. The once dominant sound of the internal combustion engine is now in the background, and other noise sources have moved to the forefront. Due to their high RPM, alternators contribute up to 40% of this total noise inside the vehicle. In order that this noise doesn't become to dominant or disturbing, imc automated the entire test sequence. The system consists of a modular imc measurement system and customized software based on the imc STUDIO software platform.

The Solar Team Twente, a team of students of the Saxion Poly Technical College and of the University of Twente (Enschede, The Netherlands) took part in this event. Together they constructed the 'Twente One' as they called their solar vehicle. With new regulations for the 2007 event, they went for a completely new and innovative design. Not only mechanically, but also electrically and electronically the Solar Team Twente uses the newest technology. The heart of the electronics featured an imc C-SERIES intelligent data logger.

Stationary and mobile testing go hand in hand in the development of modern automotive technology. Up to now, the conversion of the test vehicle was a significant obstacle when changing between mobile and stationary testing. The aim was to implement a modern data logger system that combines the requirements of mobile and stationary testing.

As engines become quieter, certain vehicle components are becoming perceivable which were previously drowned out by engine noise. For this reason, acoustic measurement now faces new challenges.

The new statutory WLTP test cycle requires a consumption measurement for each variant of a new passenger car model. The measurement procedure used by the EU as the standard for consumption values includes a measurement on the test bench and an RDE test on the road to determine realistic values. In order to cope with this test cycle in a time-saving and cost-efficient manner, imc developed a user-friendly and compact measurement box that works both on the test bench and on the road.
