The car is an extremely interconnected system, with over 100 ECUs all attempting to communicate with other systems in the car. To manage increased complexity and higher data rates as new versions of existing protocols find their way into vehicle networks (CAN FD, Ethernet), the classic flat wiring harness architecture is changing to a domain and zonal architecture with Automotive Ethernet as the backbone. Offering increased system robustness, our IVN bus line protection solutions are well suited to automotive bus protection without impeding signal integrity in this electrically noisy environment.
