HIL test bench for rear-axle steering systems
Fields of application
- Function development, optimisation and validation of rear-axle steering systems
- Analysis of performance and control in a HIL-environment
- Simulation and validation of rear-axle steering behaviour in failure scenarios
- Automated HIL road and approval tests
Test bench architecture and modules
- Mechatronic integration of rear-axle steering systems,
e.g. via- Flexibly adjustable and close-to-application mechanical fi xtures for different types of rear-axle steering systems
- Integration of control devices, sensors and fieldbus systems (CAN, FlexRay)
- Integration of test item and vehicle models
- Linear actuator to apply variable forces and positions
- Counter force: ± 12 ... ± 25 kN
- Stroke: ± 150 … 300 mm
- Adjustment speed: 500 ... 750 mm / s
- Powerful simulation of vehicle electrical systems incl. energy refeed
- Cut-off relay adaptor for highly automated simulations of electrical failures
- Measurement system to record
- Control and power signal currents of the specimen actuator and ECU
- Forces and positions
- Models and interface with real-time hardware (e.g. MATLAB / Simulink, dSpace)
- Compact dimensions and design for use in HIL labs
