Next-Generation Mobility

Next-generation mobility will be defined by safer, more sustainable and convenient ways of moving around.  The ability to efficiently and reliably transport large volumes of high-speed data within the vehicle and beyond is key to achieving this. 

 

For years the number of electronic control units (ECUs) has continually increased, ranging up to 150 ECUs per car, depending on the vehicle class.

 

The resulting physical interconnection network, establishing the links between numerous new safety relevant devices and sensors and with the next higher corresponding control layer, is becoming highly complex. For example, depending on its class, a modern car can contain up to 150 ECUs and this number is increasing.

 

In addition, with the increasing electrification of vehicle powertrains, high-voltage electronics and high-speed data links must be able to coexist with no impact on functional reliability.

 

Up to 150 ECUs in today's car.

Reliable Data Connectivity in an All-Electric Environment

This paper (updated March 2022) shows how TE addresses and ensures EMC during component development. The first version of the paper used the example of an interconnection system designed for Automotive Ethernet with the focus being primarily on point-to-point connections for sensor data fusion and data transmission via the Ethernet network. This latest version of the paper also focuses on managing EMC in data connectivity links based on coaxial technology.
