HIL test benches for chassis control systems

HIL test benches for chassis control systems

Fields of application

  • System and component development, optimisation and validation
  • Analysis of performance parameters and control quality within the HIL network
  • Endurance and HIL road tests
  • „Simulation and validation of system behaviour in failure scenarios

Test bench architecture and modules

  • „Mechatronic integration of test items, e.g.
    • Active and passive chassis components (e.g. active anti-roll bars, shock absorbers, wheel modules)
    • Steering systems for front and rear axles and, if  applicable, dynamic steering
    • Relevant ancillary components
    • Control devices, sensors and fi eldbus systems (CAN, FlexRay)
    • Vehicle models
  • „Suitable drive transmission technology to test different forces and torques
    • Electrical servo drives, linear cylinders and actuators
    • Hydraulic actuators

 

  • „Powerful simulation of vehicle electrical systems incl. energy recovery
  • „Cut-off relay adaptor for highly automated simulations of electrical failures
  • „Metrology to record
    • Control and power signals (Currents, voltages) of the specimen actuators and ECU’s
    • Forces, torques, positions, angles, accelerations and temperatures
  • „Models and interface with real-time hardware (e.g. MATLAB / Simulink, dSpace)
