15. A vehicle powered by muscle power and/or motor power, the vehicle comprising:
a hydraulic braking system, including:
a device for controlling a discharge of an accumulator of the hydraulic braking system, wherein brake fluid is discharged from the accumulator via an outlet valve, a primary circuit of the braking system, and an inlet valve into a reservoir of a master cylinder of the primary circuit, the device configured to:
check whether a discharge condition,for discharging an accumulator of the braking system is met; and
based on the discharge condition being met:
initially move the controllable inlet valve in the primary circuit of the braking system into a partially closed state over a predefined duty cycle and/or for a predefined time span, and
after the initial move, open the outlet valve of the accumulator for a predefined time span, continuously or in intervals.
