In a process for controlling the braking pressure depending on the rate of pedal operation, with the aid of a braking pressure sensor controlled by an outside force on exceeding an actuation threshold, during partial braking the actual values of the pedal travel (sactual) and the vehicle deceleration (aactual) or the braking pressure (pactual) are found and the actual values are compared with the reference or serial mean values. Correction factors are obtained from the difference between the actual and reference values and an adaptation factor is determined in a learning process over successive partial braking operations. The basic value of this threshold is multiplied by the adaptation factor to provide the actuation threshold.
