Abstract (en)
[origin: WO2018121953A1] The invention relates to evaluation electronics (50) for a vehicle brake system which is equipped with an electromechanical brake booster (50), and to a method for estimating a master brake cylinder pressure in a vehicle brake system which is equipped with an electromechanical brake booster (52), comprising the steps: estimating a first output value of the master brake cylinder pressure taking into account at least a first current strength (I (t1)) of a motor current of a motor of the electromechanical brake booster (52) at the first time and taking into account a first rotational angle (φ (t1)) of a rotor of the at the first time, defining a correction value (ΔC) as a difference between the first output value and a measured value (xmeasured (t1)) of the master brake cylinder pressure, estimating a second output value of the master brake cylinder pressure taking into account at least a second current strength (I (t1+Δt)) of the motor current of the motor at the second time and taking into account a second rotational angle (φ (t1+Δt)) of the rotor at the second time, and defining an estimated value (p (t1+Δt)) of the master brake cylinder pressure in the master brake cylinder at the second time taking into account the second output value and the correction value (ΔC).
