Steering Testing Systems

Known for their excellent reliability and performance, Inova motor vehicle steering test rigs have been used by leading car manufacturers around the world, including TRW or the Volkswagen Group. Thanks to their advanced design and cutting-edge engineering Inova test rigs accurately simulate real-life conditions, with all forces, load vectors and movement trajectories corresponding to an actual kinematics of cars.

Main Benefits

  • Comprehensive real time testing under real-life conditions (HIL)
  • EU3000 RTC advanced digital control system 
  • Canbus, Flexray integration with and Restbus simulation
Accelerated Life Testing

Inova test rigs can be used to test a wide variety of steering systems and their components, including I-shafts, electric or electro/ electro-hydraulic power assisted gears and electrically powered column drives. The test rigs can be combined with temperature chambers capable of simulating extreme use conditions, such as a cold start on a freezing winter morning in Scandinavia with temperatures plummeting to -40°C or extended operation in extreme heat over 100°C.

Test rigs communicate with the test specimen via standard car interfaces, including Can, CanFD and Flexray, while interaction with other car systems can be modelled through Restbus simulation.

Inova has rich experience in designing and developing custom and special-purpose systems, including in-production dynamic load performance comparisons against reference standards. (Special test rigs were developed for testing by production. Vibrations of steering body are measured by dynamic loading and compared with “mother” frequency spectra.)
