Virtual Test Driving

Trailer simulation: Advantages and potential usecases

  • Support of the release process for trailer stabilization functions using HiL technology
  • Test automation and parameter variation
  • Testing a variety of vehicle-trailer combinations, including multiple trailer configurations
  • Fundamental investigation of vehicle-trailer dynamics
  • Reduction of dangerous driving tests of safety critical maneuvers
  • Identification of critical vehicle-trailer combinations and loading variants

Simulation scenarios and variations for realistic test maneuvers

  • Steering impulse according to ISO 9815 or other user defined profile
  • Influence of side wind loading
  • Downhill and uphillroad profiles
  • Road damage
  • Tailer with or without brakes
  • Influence of tire profile, air pressure and wear
  • Parking maneuver, reversing with trailer
  • A variety of road friction conditions

    Simulation software
