How ABS works

Definition of ABS

For the record, anti-lock brakes were first developed for airplanes in the 1920s: they were needed to prevent skidding on landing. The acronym ABS comes from the German "Antiblockiersystem". It is an anti-lock wheel system that keeps the vehicle under control in the event of sudden braking.

Focus on the ABS system

The ABS block is a part of the overall ABS system. There are for the Audi A7 4G vehicle ...

• Wheel speed sensors: each sensor is placed in front of a rotating notched wheel that generates a magnetic field variation and induces a sinusoidal signal.
• The ABS block: more details below.
• Magnetic targets: they generate signals read by the sensors, which send these signals to the ABS computer.

The ABS block

The Audi A7 4G car manufacturer's ABS block consists of the following components, among others:

The hydraulic unit

Here are some of the components that make it up:

• Solenoid valves, of which each wheel has an intake solenoid and an exhaust solenoid valve.
• A hydraulic pump that prevents the pedal from depressing during ABS regulation.

The ECU
