A brake system for a utility vehicle includes: an electronic brake controller unit, a pneumatic parking brake circuit with at least one spring energy cylinder, a parking brake valve to control a parking brake pressure in the parking brake circuit, and at least one 3/3-way valve arranged in a pneumatic line of the parking brake circuit between the parking brake valve and at least one of the spring energy cylinders. The 3/3-way valve is actuable by the electronic brake control unit, and is configured to ventilate the pneumatic line between the 3/3-way valve and at least one of the spring energy cylinders to a predefined pressure, so as to cause the at least one of the spring energy cylinders to allow a brake, which is assigned to the spring energy cylinder, to pass into engagement.

Brake system for a utility vehicle, utility vehicle, and method for operating the brake system

Electric equipment for a vehicle with an electropneumatic service brake device, in which at least one pneumatic brake control pressure is immediately and directly controlled to the electromagnetic backup valve, which is still being closed by a current, of at least one pressure regulating module in response to an assistance brake request signal regardless of a defect of an electric service brake circuit. For a failure of the electric service brake circuit, the electromagnetic backup valve, which is then in the currentless state, of the at least one pressure regulating module is automatically opened, and the brake pressure is immediately formed in the pressure regulating module based on the at least one pneumatic brake control pressure already present in the pressure regulating module. Thus, the reaction time of a pneumatic redundancy of the electropneumatic service brake device in response to electric defects is reduced.

An electronically controlled pneumatic operating brake system, having a backup control pressure for a pneumatic fall back level, wherein the backup control pressure is generated from a compressed air supply which is independent from two compressed air supplies for a front axle circuit and a rear axle circuit. This assures additional pneumatic redundancy and facilitates omitting a pneumatic channel in a foot brake module.
