E/E development Accelerate your development with us.

In modern vehicle development, electric and electronic components are essential for functionality, comfort, safety, and mobility. Even more electric and electronic systems will be required for the car of the future.

The development of electronic systems expands over all vehicle subareas, making a close cooperation between the individual development areas obvious for us. We are your partner for the implementation of your visions, from car body, chassis and drive electronic system development up to the complex development and integration of electric drive systems.

Our core skills in the electric/electronic development area:

We handle development packages for hardware and software projects in own responsibility, or the overall responsibility for the complete system development.

Service all around the development, integration and operation of complex automotive electronic systems.

Your contact in the area of development of electric/electronic systems:

We are your partner from the bit up to the entire vehicle.

embedded systems

We conceive, develop, manufacture and test application-specific electronic assemblies to customer requirements.

key aspects:

e-mobility (ecu for electric vehicles, power management, battery management systems, power electronics, sound applications)
gateways
driver assistant systems
HMI (hardware development, HUD control)

Hardware development:

Specification
Circuit draft, selection of assembly parts
electric, thermic and mechanic simulation of circuits
Board layout, 3D package
PCB manufacturing and assembly
initiation, functional test, HIL, as well as environment tests in our own accredited laboratory

Software development:

We develop software for assistance, battery management systems, gateways for vehicle control for e-vehicles and other controls. This includes complete software development for complex systems, individual components, control units or functionalities including their integration up to the verification.

design and development of AUTOSAR application
Programming of different micro controllers in C and Assembler
development and configuration of AUTOSAR software components in C as well as model based
Integration of vehicle manufacturer standard software and supplier functions into the control unit software
Implementation of requirements as e. g. communication, diagnosis and error handling
tool based software quality (MISRA, static and dynamic code analysis of software units)
safety related software development according to ISO 26262

Prototyping:

Use of self-developed multifunctional control devices for fast, flexible and professional function implementation in test boards, on the test bench or in vehicles.

Exemplary properties:

Programming via C code
Gateway between CAN/CAN and/or CAN/LIN and/or CAN/WLAN
restbus simulation
CCP access
Sensor and actor interface
Extension modules:
+ motor driver
+ LED driver
+ outputs with higher loads
+ PWM
+ digital/analog I/O
Customer-specific functions are possible

On-board network development

The on-board network controls the voltage supply and the flow of information between components and control devices. Weight reduction, electrification of high-voltage on-board networks as well as the mechanical integration of the on-board network and its electronic components are important factors in on-board network development.

We support you with long-standing know-how and specialist competence, in particular with respect to the development and transition of 12 V on-board networks – which are reaching their limits – towards 48 V on-board networks.

System integration

System integration is an essential component of the development process according to the V model. A comparison between required and realised functionalities is performed in this area. The use of suitable integration concepts and matched time schedules allows the simultaneous integration on different functional levels. This procedure is applied in the series process as well as in for derivate and special development.

Project planning and coordination:

Preparation of product and requirement specifications
Time schedule preparation
Coordination of development tasks
Supplier management
Change management
Release management
Maintenance of systems and databases

System development:
