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
  • Sugestive Sounddesign
  • 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
     

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)
