Ensuring seamless communications within vehicles with leading-edge testing equipment.
One of the biggest challenges within the automotive industry is the development of automotive domain controllers and high-performance ECUs that are reliable, robust and able to handle huge amounts of critical data efficiently. It is essential that they communicate synchronously with various components within the vehicle such as sensors, actuators, ECUs and gateways using different communication protocols within the same unit – a demanding task for any engineer.

Developments in advanced driver-assistance systems are creating a new approach to in-vehicle network (IVN) architecture design. With today’s vehicles using at least a hundred ECUs, the current network architecture has reached its limits and the automotive industry is now focusing on a domain or zonal controller architecture to simplify network design and maximize performance. A domain controller can potentially replace the functions of many ECUs, providing capabilities for high-speed communications, sensor fusion and decision-making, as well as supporting high speed interfaces for cameras, radar, and LiDAR.

Domain controllers for modern vehicle zonal architecture
Your work requires you to perform efficient and repeatable test of compatibility, performance and signal integrity for high-speed digital interfaces while also verifying EMI of circuit boards, thereby ensuring seamless communications throughout the vehicle. The specific tests include:
All of these tasks can be achieved with a single test setup based on the R&S®RTP oscilloscope (complemented by a network analyzer and power supply).
