The operation of the ABS block

What is the purpose of the ABS block?

Since January 1, 2003, the Highway Code requires that an ABS block be installed on every automobile. The ABS block refers to the anti-lock braking system of the wheels to prevent, when braking with the foot on the floor, the wheels from locking.

Before explaining in detail the ABS block, it is important to identify the ABS system entirely. We distinguish for the BMW 5 series model ...

• The magnetic targets: they vary the output signal which takes the appearance of a square signal of variable frequency.
• The wheel speed sensors: they measure the speed of rotation of the wheels.
• The ABS block: the information below helps to understand the importance of this element.

The hydraulic motor

It uses the oil flow that is pushed into the hydraulic circuit by a hydraulic pump and transforms it by a rotary motion to drive another device such as the gearbox or wheel, etc.

The hydraulic unit

Many components make it up including:

• Pressure accumulators which are none other than pressurized gas reservoirs used to provide a large flow rate for a short period of time.
• Electronic brake proportioner, which has a complementary role managed by the ECU.
• Solenoid valves with a presence of ABS regulation on the rear wheels.

The ECU

This is the part that receives the information that comes from the brake pedal.
