Abstract:
A method for compensating for an accumulator pressure in an electrohydraulic braking system of a motor vehicle, in which a valve arrangement controls an input of a hydraulic fluid from a pressure accumulator into wheel brake cylinders, the hydraulic fluid being deliverable by a pump into the pressure accumulator, the method comprising the steps of:defining a variable corresponding to at least one of a driving situation and a drivers's command and representing a set point wheel pressure with which at least one wheel brake cylinder is chargeable to achieve an optimal braking action; comparing the variable to another variable representing an accumulator pressure in the pressure accumulator and providing a comparison result, wherein the step of comparing continually takes place at regular intervals; and increasing the accumulator pressure in response to the comparison result falling below a predefined minimal difference between the variable representing the setpoint wheel pressure and the another variable representing the accumulator pressure.
