BrakeiL
BrakeiL is a real-time rig for testing complete brake systems, including (depending on the vehicle under test):
- Brake pedal
- Brake booster (pneumatic, electric, electromechanical, etc.)
- Master cylinder
- ESC module
- One-box brake system
- Hoses, callipers, pads, and discs.
The brake pressure is directly built-up by the master cylinder and all brake system functions (ABS, ESC, etc.) are physically performed by the devices under test.
The DUTs receive the raw wheels speed signals from the M42 Wheel Speed Sensor Emulator (WSE) and the communication with the virtual vehicle is over the EtherCAT protocol. The simulation loop is closed on the brake pressure, measured on the four calipers.
BrakeiL enables human-driven tests into driving simulators or fully robotized tests as a stand-alone unit and it is suitable to develop, tune and validate braking functions in:
- Vehicle dynamics
- ABS/ESC
- Brake pedal feel
- ADAS/AD
- FUSA/SOTIF
- And more…
