An electronically controllable pneumatic brake system in a vehicle includes wheel brakes for braking respective wheels of the vehicle. Wheel brakes of at least one vehicle axle include spring-loaded cylinders for implementing a pneumatic parking brake in a parking brake braking circuit of the vehicle. The brake system further includes an electronically controllable monostable bypass valve, wherein the monostable bypass valve is disposed between a manually operated parking brake valve and the spring-loaded cylinders. The monostable bypass valve controls, in a first switching position, a bypass control pressure based on an actuation pressure produced by the parking brake valve to implement a manually specified parking brake force. The monostable bypass valve further controls, in a second switching position, a bypass control pressure depending on a venting pressure prevailing in a bypass vent connection to implement an electrically specified parking brake force.
