Dynamic Brake Control

Dynamic brake control (DBC) assists the driver in emergency braking situations by automatically increasing the brake pressure.

Advantage: Shortest possible stopping distances in emergency braking situations, because the ABS control threshold is reached at all four wheels.

In emergency-braking situations, drivers often fail to apply sufficient force to the brake pedal. ABS regulation is then not activated.

In the following situations, the return pump increases the brake pressure until ABS regulation is activated:

• When the brake pedal is rapidly depressed with insufficient pedal pressure
• When the brake pedal is depressed slowly and the demand for deceleration is subsequently high, after one wheel reaches the ABS control threshold.

Which wheel locks first depends on load and coefficient of friction of the road surface.

Example of a typical situation:

The traffic slows, making light braking necessary at first, but then demands as short a stopping distance as possible.
