Abstract
A method of shortening the braking distance in critical driving situations uses the criterion of exceeding of a first threshold value by the actuating speed of the brake pedal (v.sub.BP) by the vehicle driver for initiating an automatic braking operation. A brake pressure (p.sub.B,max) which corresponds to the value of the brake pressure with optimum deceleration of the vehicle is built up automatically immediately after initiation of the automatic braking operation.
Claims19
A method of shortening a braking distance in critical driving situations, comprising the steps of:
- using an exceeding of a first threshold value, said first threshold value being greater than zero, by an actuation speed of a brake pedal caused by a vehicle driver as the only criterion for initiating an automatic braking operation;
- and,
- automatically building up a greater brake pressure than a brake pressure obtained from a position of the brake pedal immediately after initiating the automatic braking operation.
