This applies to both passenger cars and bicycles in equal measure. Malfunctions in the motor or gear control systems, erroneous measurement values or interferences in the on-board electronics caused by electromagnetic fields and frequencies are highly dangerous, e.g. if the emergency braking assistant triggers a full stop at high speeds due to electromagnetic interference. The first malfunctions of this kind were already observed many years ago, when radio interference caused vehicle airbags to suddenly inflate. Testing the electromagnetic compatibility (EMC) of standard electrical equipment, such as household appliances, has been a standard legal requirement for some time now, and these tests are carried out in specially designed test chambers. EMC testing in vehicles, though, involves a lot more work, as perfect scores also need to be achieved when driving – i.e. under high current. This can only be done under load, meaning on a braked chassis dynamometer. In addition, the flawless functioning of all electronic components under high stress and all weather conditions must also be tested. It must also be ensured that new systems could be integrated at a later point, as does the resistance to interference from electrical fields. If changes are made to the vehicle’s electronic systems, the EMC test or evaluation must be repeated. The DEKRA Automobile Test Center in Klettwitz has been offering a wide range of functional tests, safety tests, and measuring services for many years now. The DEKRA Automobile Test Center in Klettwitz has been offering a wide range of functional tests, safety tests, and measuring services for many years now. To meet the growing demand for such services, a new test laboratory has been set up in Stuttgart which can accommodate and conduct all EMC tests required for the electromobility sector. This is good news especially for the many companies operating on this market in the greater Stuttgart area.
