Abstract
A method and a device 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, in which a variable is defined that corresponds to a driving situation and/or a driver's command and that represents a setpoint wheel pressure with which at least one wheel brake cylinder is chargeable to achieve an optimal braking action, the variable is compared to another variable representing an accumulator pressure in the pressure accumulator to provide a comparison result, and the accumulator pressure is increased in response to the comparison result falling below a predefinable minimal difference between the variable representing the setpoint wheel pressure and the another variable representing the accumulator pressure.
