»Digital Commercial Vehicle Technology«

Digitalization and intelligent networking with the environment play an increasingly important role in the development of commercial vehicles.

The Fraunhofer innovation cluster »Digital Commercial Vehicle Technology: Vehicle - Environment - Human - Interaction (DNT/FUMI)« has been established in Kaiserslautern. The cluster is a decisive factor for the development of the area and has defined new forward-looking topics in cooperation with industrial partners.

Starting in 2018, the Innovation Cluster and all projects will be integrated into the Center"Digital Commercial Vehicle Technology"of the High Performance Center Simulation and Software Based Innovation.

Each of the projects listed specifies a working area that is clearly defined by industrial needs and covers several subprojects. Each topic can be assigned to one of the following three areas:

  • Basic research
  • Development of methods
  • Tools and industrial application projects

The Focus of the Center:

The center »Digital Commercial Vehicle Technology« focuses on those areas that have already been defined in the innovation cluster. The main topic of these areas is »Energy Efficiency, Reliability and Operational Safety«. The center is divided into three projects:

  • Project 1: »Energy and Process Optimization of Commercial Vehicles«
  • Project 2: »Automated Driving Functions, Assistance- and Monitoring Systems«
  • Project 3: »Human-Machine-Interface«

Project »Energy and Process Optimization of Commercial Vehicles«

Due to stricter emission standards, the factors energy consumption and pollution emission become more and more important in the development of trucks and machinery for construction and agriculture. Velocity profiles are a significant parameter for the indication of driving dynamic strains. The method and simulation package »Virtual Measurement Campaign« (VMC®) allows determining the velocity profiles based on given route data and information on the driver and the vehicle.


Objective:

Virtual measurement campaigns like the VMC® provide the possibility to evaluate and optimize the energy and resource efficiency of vehicles with regard to the intended purpose or area of use at an early stage. The objective of the project is to develop and improve virtual measurement campaigns.

Project »Automated Driving Functions, Assistance- and Monitoring Systems«

Today, numerous driver assistance systems and monitoring systems are available to almost every vehicle. Still, there is a high demand for further functions, which help and support the driver or accelerate the operating process. Due to high driving performances, commercial vehicles are predestined for automated driving. An intelligent connection and digitalization of vehicles advance this development.

 

Objective:

With the driving simulator RODOS®, new assistance and monitoring systems as well as new driving functions can be developed. In the simulator, the vehicle itself is present as a numeric model, whereas the driver and a part of the surroundings (in this case the cabin) are real. Simulation components can flexibly be integrated either as virtual models or as real objects. With the objective to realize simulations under real-time conditions, the efficiency of the coupling of all factors is especially focused.

Project »Human-Machine-Interface«

Ergonomics and the working quality are central topics in the development of commercial vehicles. In addition, employees demand an interesting and safe working space. In order to respect these aspects, it is essential to understand the working processes in detail. 

The interactive driving and motion simulator RODOS® offers a modular platform, in which a real human can be integrated into a simulation environment consisting of virtual and real components. On the one hand, this avoids the use of a physical simulator in the virtual predevelopment. On the other hand, it allows investigating the user’s behavior and his cognitive load with a stronger correspondence to reality than it would be possible in completely virtual environments.


Objective:

The project focuses on one special aspect in the research on RODOS®, namely the consideration of the human perceptual mechanisms in virtual environments. This is important for the improvement of such testing environments.
