Brake pressure modulator of an electronic braking system of a utility vehicle

A brake pressure modulator (1) of an electropneumatic brake system of a utility vehicle, which has pneumatically actuatable wheel brakes (7a, 7b, 7c, 7d) at brakable vehicle wheels (6a, 6b, 6c, 6d), the brake pressure modulator (1) comprising:

• at least two pressure control circuits (13, 14) combined to form a modular unit, in which the pressure control circuits (13, 14) are each associated with a brake circuit (9, 10) of a vehicle axle, in which each of the pressure control circuits (13, 14) is configured to be connected to a dedicated compressed air reservoir (4, 5),
• the modular unit further including a common electronic controller (2) for the pressure control circuits (13, 14),
• wherein the at least two pressure control circuits (13, 14) are configured to be controlled independently of one another by the electronic controller (2),
• wherein each of the at least two pressure control circuits (13, 14) has a dedicated venting path (19, 19a),
• wherein at least one of the at least two pressure control circuits (13, 14) has a dedicated redundant control pressure path (21), and
• wherein at least one other of the at least two pressure control circuits (13, 14) has a device (16a) for forced venting via the dedicated venting path (19a) upon occurrence of a failure.
