The ABS system to keep control of the automobile


Before explaining the ABS block, it is important to understand the ABS system as a whole. There are for the Mercedes S-Class W221 automobile ...

The motor driving a hydraulic pump

It transfers hydraulic energy into mechanical energy.


The hydraulic unit

It consists of several components including...

  • Solenoid valves that eliminate the need for a brake compensator.
  • Pressure accumulators that are pressurized gas reservoirs that can hold a variable volume of a pressurized liquid.

The ECU

Warns the driver of a technical problem via a warning light on the dashboard.
