COMFORT ELECTRONICS

EVERYTHING IN VIEW. EVERYTHING UNDER CONTROL. ALSO THE FUTURE.

We develop embedded control units for series application and support our customers with development and integration of control switches for infotainment, light, air condition, driving assistance or rear-seat entertainment. For this end, we apply the latest software architectures like AUTOSAR. We also work with the process model Automotive SPICE®.

PROJECT

For MERCEDES BENZ CARS we supervise and optimize the development process for instrument-cluster software for series vehicles.
 

TASKS

  • Supervision and optimization of the development process for instrument-cluster software for series vehicles
  • Management of new features, design modifications and international legal provisions 
  • On-time roll-out of new software in the Daimler plants worldwide
  • Close cooperation with the customers and its suppliers to be able to maintain a continually high quality in the delivered software

 

CHALLENGES

We were confronted with the challenge of delivering the correct software with the correct hardware to the correct place on time. This is a skill we enjoy to be responsible for. Another challenge lies in coordinating and managing the process in an international environment, which only works with close cooperation and day-to-day contact with customers and suppliers. It is our responsibility as well to be aware of legislative changes in foreign countries like alerts in case of speeding, and to adapt these in instrument-cluster software immediately. In such cases, it’s up to us to react reliably and at short notice. As such legislative changes have to be retrofitted in vehicles of older generations, our range of tasks then also includes the after sales market. 
 

SOLUTION

With a well-established, highly qualified team we carry the responsibility that in Daimler plants around the world the correct and defect-free software is installed in the right vehicles, including the respective hardware components of the instrument-cluster. In this way we ensure that all relevant driving data and safety relevant vehicle information is visualized for the driver.

The result of our work is demonstrated every day, on streets around the world. And we can observe and experience for ourselves the success of our work in almost every Daimler car. With the series supervision of the instrument-cluster we are able to co-design and optimize the end product “vehicle” of our customer Daimler around the world.

PROJECT

In this project, we have developed controls for Master Light Switch, MMI Switch and Console Switch Pack from Bentley for our customers BJAUTOMOTIVE GMBH and BENTLEY MOTORS LTD.
 

TASKS

  • Development of hardware and software including qualification
  • Design and product validation
  • EOL software
  • Drafting of specifications and review of requirements
  • Creation of concept
  • Drafting of circuit diagram, layout and Gerber data in ORCARD
  • Test planning and coordination of development and test activities
  • Set up of test cases
  • Conducting of component and system tests
  • Registering of defects in the defect management system
  • Drafting of project reports and evaluation for OEM and tier 1
  • Weekly telephone conferences and monthly meetings with OEM and tier 1

CHALLENGES

In this project, we were confronted with a number of challenges: The premier integration of AUTOSAR, the highly dynamic changes in requirements, as well as additional demands. Overall, we had to deal with a strict schedule which we could meet only because of our existing HW and SW modules, and thanks to our internally conducted EMV and ESD measurements. As tier 2, we are direct contact partner of tier 1 and OEM and are coordinating communication. Due to defective modules in the AUTOSAR delivery, we were faced with the challenge of creating workarounds.
 

SOLUTION

Despite time-sensitive factors, the project is running according to plan, thanks to the great performance of the project team, which dug into the topic quickly and interacted perfectly. Any expectations regarding functionality and time frame were surpassed.

With the first-time, successful integration of AUTOSAR and an efficient coordination of an international project with all parties involved we have proven ourselves as a reliable and competent tier 2 partner in this challenging segment.

Magneti Marelli
 

PROJECT

For our customer MAGNETI MARELLI GMBH we conduct the system integration, system validation and front desk activities of the instrument-cluster development for Porsche, Audi and Volkswagen.
 

TASKS

  • Compilation of test cases to ensure Automotive Spice® conform test coverage
  • Drafting of test specifications for the realization of automated tests in the offshore test facilities of the customer
  • Control and ensuring of the test quality of the offshore test facilities
  • Conduction of system tests in the laboratory and in the vehicle
  • Defect registration of OEM with defect analysis and control of the reduction process
  • Interface function with the OEM in the test segment
  • Realization of tests for ensuring the functional safety according to ISO 26262 with automated tests
  • Interface function with requirements management and system engineering

CHALLENGES

Here, we were facing the challenge to ensure the required test coverage in a dynamic test environment. Especially guaranteeing workable results in the offshore test facilities required continuous and close cooperation across countries and cultures. 

Another aim was to take on tasks at the interface to the OEM reliably and with short reaction times. New jobs had to be managed diligently, and customer requests had to be answered at short notice, which required some flexibility. 

 

SOLUTION

With our long-term experience in integration and qualification of EE systems, our projects soon produced viable results. Our highly trained employees and well-established teams provided added value for our customer by adapting to changing demands with consistently high efficiency. 
 

With our methodical approach and personal dedication, we have gained the reputation of a technically versed and reliable partner to our customers.
