Brake-in-the-Loop

Functions

Brake-in-the-Loop is a mechatronic test bench that enables to test and validate complete braking systems. With the highly dynamic brake actuators, deterministic and reproducible braking maneuvers up to emergency braking can be performed. Furthermore, a wet brakes test approach including hydraulic components is also possible. The Braking-in-the-Loop test bench is suitable for conventional mechanic brake boosters, iBoosters, 3-in-1 ESC configurations and brake—by-wire systems.

Applications

  • Active vehicle subsystems intertwined with the braking system
  • Scalable, modular solutions for hybrids or electric drives
  • Validation of regenerative brake strategies for vacuum-based and vacuum-independent regenerative braking systems
  • Sizing and calibration of brake system ECU
  • Fail-safe tests and functional tests according to ISO 26262
  • Simulation-based ESC homologation according to ECE R13-11 and ECE R13-H
  • Validation of redundant braking systems for fully automated driving
  • Adaptive pedal characteristics using programmable pedal characteristic curves
  • Configurable for trucks and pneumatic braking systems
