ABS(Anti-Lock Brake System)
■ Bosch ABS 5.3
- 4-Sensor 4-Channel type
- ABS with EBD type
■ Functions
- Steerability
- Stability
- Stop Distance
■ EBD
Electronic Brake force Distribution
Brake force distributed by HECU instead of
proportioning valve
EBD Modulation * EBD control example
Sorento
Advantages of EBD
- Significant improvements have been made in brake performance
- EBD with weight distribution sensor has been incorporated for the
optimum function of 4 channel 4 sensor type.
- Approach to ideal brake-force distribution
- Adaptive to different loading conditions
- Constant brake-force distribution during vehicle life time
- Monitoring of EBD-function
- Minimal extension of ABS hardware required
