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

Sorento

EBD Modulation * EBD control example

- 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

Advantages of EBD
