Abstract:
A method for controlling a brake system of a motor vehicle, comprising:actuating a valve arrangement using an electrical system to adjust a brake pressure of wheel brakes of the brake system, the brake pressure being adjusted as a function of a braking input provided by a driver of the motor vehicle; switching on a controllable pump of a pressure supply arrangement to charge at least one accumulator of the pressure supply arrangement in preselected operating states; determining a predetermined setpoint value as a function of a pulse duty factor of a driving signal of the pump and the pressure supply arrangement; and monitoring an operating of the pressure supply arrangement by: comparing a change value to the predetermined setpoint value, the change value representing a change in pressure of the accumulator, and detecting at least one fault condition based on the comparison of the change value to the predetermined setpoint value; wherein the monitoring step is performed only when the brake system is not in a condition of volume removal from the at least one accumulator during a braking operation.
