EBB-in-the-Loop
Put electromechanical brake boosters to the test
Modern electronic/electromechanical brake boosters replace conventional mechanical brake boosters. They use an electric motor for pressure build-up to enhance functionality. Modern brake boosters are also useful during special conditions such as emergency braking since they rapidly build up brake pressure in hydraulic lines.
To ensure the safety of brakes in every modern vehicle, electronic brake boosters can be tested with the EBB-in-the-Loop test system that combines virtual road tests with a mechatronic test bench.
What is EBB-in-the-Loop?
EBB:
- Stands for electronic brake booster
- Uses an electric motor instead of a conventional assistance system to assist the driver when applying the brakes
in-the-Loop:
- Refers to both open-loop and closed-loop test procedures for the development and validation of EBB systems
- EBB-in-the-Loop enables testing and validation of control units and complete EBB systems
- Tests are carried out using virtual test driving on the test bench
How can EBB-in-the-Loop be used?
- Testing of real brake booster systems including all necessary hydraulic components (hydraulic lines, brake fluid, etc.) in open- and closed-loop maneuvers
- Calibration and optimization enable early development and testing of brake boosters
- Validation of brake booster systems for partially to fully automated driving (level 3 to 5)
- Fail-safe tests and functional tests in accordance with ISO 26262
- Deterministic and reproducible braking maneuvers up to full emergency braking
