Research Focus

The main focus is on methods and processes for the development and validation of user-oriented mobility systems. One of the research topics is the continuous integration of simulation and testing in the field of energy efficiency and NVH, as well as model-based system development and the design of validation environments. Essential aspects and sub-topics are:

  • NVH (complete vehicle and components)
  • Comfort objectification and evaluation methods
  • Energy-efficient driving and operating strategies
  • Validation of ADAS (advanced driver assistance systems)
  • Connected development and validation in a global product development environment
  • Model-based Systems Engineering
  • Use-case-based validation methods for components up to multimodal mobility concepts
  • Human-machine-interaction

 

Service Offer

We are your partner for questions concerning development and validation in the context of NVH, drivability and energy efficiency on the basis of a methodical approach considering systemic influencing factors.

  • Joint development and validation of innovative, needs-based products
  • Conception of suitable validation environments
  • Support by and implementation of Model-Based Systems Engineering methods
  • Practical, theoretical and experimental examinations at our facilities or in your company with mobile measuring technology (e. g. 3D laser scanning vibrometry)
  • Assistance in carrying out reproducible driving and roller dynamometer tests
  • Analysis and optimisation of NVH behavior
  • Analysis and optimisation of operating strategies
  • Model identification and time-efficient testing
  • Acoustic measurements inside and outside the vehicle (e. g. dummy head measurements, simulated passing)

Equipment

  • Acoustic roller test bench: 2-axle driven roller dynamometer with vehicle-in-the-loop technology in the semi-open space (lower cut-off frequency of 63Hz)
  • Driving robot (SAP 2000)
  • 3D-Laser-Scanning-Vibrometer (PSV 3D) for contactless and non-reactive detection of 3-dimensional vibrations of surfaces
  • 3D sound intensity probe (LMS SoundBrush)
  • Artificial head, uni and triax accelerometers, mobile fuel gauge, free-field microphones, 40-channel front-end and AFT TORnado
  • Modeling software based on SysML
  • IPEK driving simulator with force feedback pedal
  • Various experimental vehicles (conventional, hybrid, electric)
