E/E systems in vehicle development as the basis for modern vehicle functions
Modern vehicles are increasingly evolving into complex, networked systems.
Up to 100 control units and several kilometers of cable illustrate how much the importance of E/E systems has increased in vehicle development.
These systems form the basis for:
Comfort features
Security features
Energy and data management
Complexity arises from interconnectedness
The challenge lies not in individual components, but in the integration of numerous subsystems into a functioning overall architecture.
These include, among others:
Control units and software
On-board electrical system and power distribution
Sensors and actuators
Communication interfaces
👉 Only the interplay of these elements enables a stable and reliable system.
Requirements for modern E/E architectures
Today, E/E systems must do far more than just process signals.
Key requirements are:
efficient energy management
reliable communication between components
electromagnetic compatibility
Scalability and expandability
secure integration into existing vehicle architectures
From interpretation to real integration
Besides the concept, the practical implementation is crucial.
E/E systems must:
be physically integrated into the vehicle
be tested under real-world conditions
reliably work together with mechanical and structural components
👉 Especially in complex vehicle projects, it becomes clear that theory and practice must be closely intertwined.
Prototyping and validation as key
A key component of the development process is the construction and testing of prototypes.
This includes:
Development of prototype cable harnesses
Integration of control units and components
Testing and validation of functions
Analysis and optimization of system behavior
👉 These steps are crucial for identifying errors early and designing stable systems.
Our approach: E/E systems as an integrated assembly
For us, the development of E/E systems is not an isolated topic.
It is part of a holistic vehicle development process that integrates mechanical, structural, and electronic systems.
In doing this, we combine:
System design and architecture
Integration into existing vehicle platforms
Building and testing prototypes
Implementation until a working solution is achieved
This results in robust and coordinated systems that function reliably in real-world use.
