Trends in e-mobility. Measuring and testing technology for the car of the future.

The paradigm shift towards autonomous driving can only take place if, among other things, all electronic components and vehicle functions work together in a coordinated and error-free manner. The introduction of innovative test solutions is necessary for the test management of increasingly complex electronic systems and industry standards in the automotive sector in order to meet the requirements for safety and the benefits of e-mobility.

Test applications in e-mobility.

Modern Advanced Driver Assistance Systems (ADAS) are playing an increasingly important role in vehicle safety and comfort. Even the smallest error can lead to an incorrect assessment of the situation with serious consequences. The complexity of the technologies used for radar, V2X communication or emergency calls (e-call) etc. requires precise automotive tests to ensure maximum safety and reliable functionality.
