Abstract

The invention relates to a method for setting a trigger threshold value for an automatic braking operation. When the actuating speed of the brake pedal exceeds a threshold value, automatic braking operation is initiated, and a brake pressure is increased relative to the brake pressure corresponding to the position of the brake pedal. During each brake actuation a relation is formed between the pedal travel of the brake pedal and the derivative of the vehicle deceleration with respect to the pedal travel. A correcting value is defined from this relationship and the threshold value for automatic braking is determined as a function of a preset threshold value and the correcting value.
