Test house for head unit system functions.

Customer: OEM.

 

Background:

To guarantee the smooth market launch of an infotainment system (in short: head unit), various system functions had to be validated at all stages of development. Since the system went through a series of development stages until it was ready for the market, the validation and logistics costs were extremely high.

Customer requirement:

Development of an overall test strategy with concrete solution approaches

Solution:

Automated testing was the key to success: using a framework developed in-house, we automated up to 80 per cent of test activities. Since this covered an extremely wide range of test cases, the project was brought to a very successful conclusion.

We met all the customer's expectations, and in some cases exceeded them. The developed framework remains an integral part of the cooperation.

   

 

Bluetooth test strategy.

Customer: OEM.

 

Background:

The customer needed an overall test strategy for targeted use of the capabilities provided by the Bluetooth interface in the car. The customer had previously used different approaches depending on the car model range and department. As a competent technology partner, our duty was to analyze and standardize these approaches.

Customer requirement:

Development of an overall test strategy with concrete solution approaches

Solution:

  • Analyze the existing test processes, automation potential, and tools
  • Provide Bluetooth training for the customer's employees
  • Define new processes, tools, and test automation solutions
  • Develop a customer-specific Bluetooth analysis tool

 

 

Fault/supplier interface management tool.

Customer: OEM.

  

Background:

To optimize the fault management process at the supplier, it was necessary to develop an interface tool. The old method of integrating fault reports from the customer into the supplier's workflow was no longer sufficient, given the growth in the number of faults and also the interfaces. In addition, a new XML interface implemented by the customer for its database meant that adaptation was required at the supplier.

Customer requirement:

The customer needed a software interface solution that would enable the Tier 1 fault manager to easily query fault lists and also provide feedback. A key requirement was a user-friendly interface, optimally adapted to the fault management workflow between the customer and supplier.

Solution:

  • Workflow analysis and requirement coordination
  • Clarification of the software interfaces and contact persons
  • Software design
  • User interface design
  • Software implementation
  • Integration and acceptance testing

 

 

UML model maintainer.

Customer: GENIVI.

  

Background:

The customer wanted the release process for the GENIVI standard to be model-based. This required the development and implementation of a concept and training of the users.   

Customer requirement:

The customer was looking for a company to take on full responsibility for the UML model and perform the following tasks:

  • Management of the UML model including specification, integration, testing, documentation, and training of end users
  • Continuous improvement of the release process
  • Supporting the system architect team
  • Quality assurance of the standard

Solution:

The standard will now be created from the UML model using a plug-in for the Enterprise Architect. A central point of contact is available to the consortium for further enhancements and application issues.

Our solution received the GENIVI Alliance "Most Valuable Contributor" award in Gothenburg, May 2014.

 

  

Driver assistance systems.

Customer: OEM.


Background:

Two camera-based systems were already in development:

  • KaFAS (camera-based driving assistance system) detects traffic signs and objects.
  • iCAM (integrated camera) provides visual assistance during parking maneuvers and detects objects.

Customer requirement:

Support with the following topics:

  • Preventative pedestrian protection
  • Speed limit information
  • Video ACC (support for validation and evaluation tools)
  • Ethernet function owner as well as testing and validation
  • Chief engineer, problem management, and series production support

Solution:

  • Support during development
  • Provide product expertise
  • Manage the supplier
  • Release software versions
  • Manage the project team
  • Integrate measurement technology
  • Develop evaluation tools

 

  

Qualification of CAN control units.

Customer: OEM.


Background:

During car development, joint releases are planned after certain blocks of time. These validate the system communication. For this to be possible, the CAN control units must be reliably, quickly, and cost-efficiently qualified.

Customer requirement:

The customer was looking for a company to ensure qualification of the control units over the entire course of the development process for multiple car model ranges. Consistently high test quality and complete execution had to be guaranteed, even with joint releases taking place in parallel.

Solution:

The project was successfully implemented. A decisive factor here was the conclusive and convincing concept as well as our high flexibility, commitment, and in-depth technical knowledge. Since the customer was very happy, we were assigned further service packages.

 

 

HMI software development and systems integration for instrument clusters.

Customer: OEM.

  

Background:

HMI software development was previously the responsibility of the instrument cluster supplier. This meant a significant amount of coordination was required to extend and adapt the display contents. The number and scope of the displays increased, and at the same time the OEM wanted a clear corporate design for its customers. For this reason, the OEM decided, with the help of a software development service provider, to separate the development of the HMI software component from the rest of development of control units and standardize it.

Customer requirement:

HMI software development and systems integration for a new kind of instrument cluster family. The integrated instrument cluster electronics were to be consistently separate from the design front end. The displays themselves were to make greater use of three-dimensional display components. The software development process was to be adapted to this end.

Solution:

We developed a new software architecture for the customer. To convert existing function and business logistics, an optimized modular software system for 2D and 3D content was designed.

The software tool chain and the development workflow were also optimized and extended to take account of the future range of variants. The TAF framework was also used and adapted. This made possible a significant increase in the automation level of the software acceptance tests.
