Abstract
In a method of controlling the braking pressure as a function of the rate of pedal actuation, by way of a braking pressure generator which is driven by an independent force when an actuation threshold is exceeded, the actual values of the pedal travel and the vehicle deceleration or the braking pressure are determined during partial braking operations, and the actual values are compared with the nominal values or series mean values. Correction factors are derived from the respective deviation of the actual values from the nominal values, and an adaptation factor is determined in a learning process over successive partial braking operations. To determine the actuation threshold, the basic value of the threshold is multiplied by the adaptation factor.
