Abstract

A method for controlling the operation of a hydraulic braking system of a vehicle and in particular a vehicle drivable using muscle power and/or—in particular additionally—using motor power, an electric bicycle, e-bike, pedelec, or the like. In the method, it is checked whether a discharge condition for discharging an accumulator of the braking system is met. If the discharge condition is met, initially a controllable inlet valve in a primary circuit of the braking system is set into a partially closed state over a predefined duty cycle, in particular of 10%, and/or for a predefined time span and then an outlet valve of the accumulator is opened for a predefined time span—continuously or in intervals—so that brake fluid is discharged from the accumulator via the outlet valve, the primary circuit, and the inlet valve into a reservoir of a master cylinder of the primary circuit.
