SBW-in-the-Loop
Develop, test and validate steer-by-wire steering systems
Steer-by-wire (SBW) offers considerable future potential to improve driving behavior, especially with the increasing presence of electric vehicles and demand for autonomous driving. The special feature of steer-by-wire steering systems is that there is no mechanical connection between the steering wheel and the wheels to be steered. Instead, steering input commands are transmitted to the control unit via sensors and ultimately to the controlling actuator. The SBW-in-the-Loop test system facilitates specific and reproducible testing of steer-by-wire steering systems for cars, trucks and special applications such as racing cars.
Who benefits from SBW-in-the-Loop?
- From OEMs to suppliers, development engineers for SBW steering systems can use our test system individually
- Developers and engineers working in the fields of chassis development, advanced driver assistance systems and automated driving functions
- Companies can also rent a test system (SBW-in-the-Loop) at the headquarters in Karlsruhe and carry out their tests on site
What is SBW-in-the-Loop?
SBW:
- Stands for steer-by-wire and therefore for the specific development and testing of SBW steering systems
in-the-Loop:
- Refers to both open-loop and closed-loop test procedures for development and validation of steering systems
- Comprehensive testing of SBW steering systems using a test bench and optimized software interface
How can SBW-in-the-Loop be used?
- Testing of the real SBW power pack (ECU with the motor) in open- and closed-loop maneuvers
- Testing of the real SBW power pack (ECU with the motor) in open- and closed-loop maneuvers
- Modular test bench for function validation of SBW systems (configurations with two or three ECUs)
- Execution of comprehensive variance tests for system optimization
- Testing automated driving functions through simple integration of electric steering system components
- Testing automated driving functions through simple integration of electric steering system components
Use Cases
Virtual calibration and test bench simulation for the efficient development of steer-by-wire
To efficiently advance development, Schaeffler Paravan tests its steer-by-wire application using an integrated approach that combines test bench and simulation. Close alignment between model-based and simulation-supported requirements development enhances both the accuracy and the flexibility of requirements definitions. As virtual calibration advances maturity at an earlier development stage, it accelerates and optimizes the development process as a whole.
