Setting braking pressure for vehicle involves releasing first braking pressure, applying second pressure for long-term parking, applying first pressure for start-up, removing to drive off

摘要

The method involves maintaining the required braking pressure to ensure that a vehicle is not moved by an external force by determining the difference between a drive torque and an external moment on the vehicle and generating a first braking pressure by a first brake(3) so that a braking force is exerted on at least one vehicle wheel if the drive torque is less than the external moment. The first braking pressure is released and a second braking pressure simultaneously produced by a second brake(4) if a long-term parking condition is fulfilled. The second braking pressure is released and the first braking pressure is applied simultaneously if a start-up condition is fulfilled and the first braking pressure is released if a driving off condition is fulfilled.
