In a method for operating a brake system of a vehicle during autonomous driving of the vehicle, a presence of status information relating to a driving command unit which controls the autonomous driving is checked by a brake control unit of the brake system. If the brake control unit detects that the status information is missing or detects status information which indicates an error of the driving command unit, a control signal which controls the autonomous driving in the longitudinal and/or transverse direction is generated by the brake control unit from current environmental data and/or driving parameters.

Disclosed is a method for operating an automated parking brake for a motor vehicle comprising at least one braking mechanism with a brake piston. In said method, the parking brake moves the brake piston by means of an actuator between an idle position, in which the brake piston applies no braking moment, and a braking position, in which the brake piston applies a braking moment, in relation to a brake disk, and during a disengagement process of the parking brake, a reference point is determined in which the brake piston is located in a position in which it applies substantially no braking moment and which is between its idle position and its braking position. The method according to the disclosure is characterized in that the reference point is estimated taking into account an extrapolation of a variable describing the disengagement process.
