Abstract
Method for determining a model upstream pressure (P) using a mathematical model in a motor vehicle brake system. An electrically controllable hydraulic valve () control brake pressure on a wheel brake. Wheel sensors () provide a vehicle speed signal. From the vehicle speed signal (v) generating at least a first low pass filtered vehicle speed signal (V, V, V) for using with a first limit frequency (f, f, f), from whose time profile the point in time (t) of a significant decrease is detected, used for determining a time duration (Timer) starting with deceleration of the vehicle, which ends at the onset of regulation of the braking process. For the classification of the actuation speed of the brake pedal () the time duration (Timer) is compared with one or more threshold values (SW, SW). Depending on the comparison, determining a model upstream pressure (P) using the mathematical model.
