Abstract

A method and system for determining a brake pressure which is predefined by a vehicle control system involve effecting a vehicle braking process initiated by an electronic braking system and/or the vehicle driver, determining a vehicle deceleration a, and a brake pressure pestim, comparing the brake pressure pestim against a reference pressure pB, terminating the braking process triggered by the electronic braking system when pestim is less than the reference pressure pB, or continuing the braking process triggered by the electronic braking system when pestim is greater than or equal to the reference pressure pB.
