Abstract

The invention relates to a brake pressure modulator (1) of an electronic braking system of a utility vehicle, which is designed as a constructional unit with at least two pressure control circuits (13, 14). The wheels (6a, 6b, 6c, 6d) of the vehicle, which can be braked, comprise pneumatically actuated wheel brakes (7a, 7b, 7c, 7d). The pressure control circuits (13, 14) are respectively associated with a braking circuit of a vehicle axle, each pressure control circuit (13, 14) comprises a compressed air supply system (4, 5), at least one redundancy control pressure path (21), at least one ventilation path (19, 19a) and a common electronic control unit (2) being provided for the pressure control circuits (13, 14). Said pressure control circuits (13, 14) can be controlled independently from each other by means of the electronic control unit (2). According to the invention, in order to be able to produce the multi-circuit brake pressure modulator (1) in a constructionally simple manner which is also compact and economical, each pressure control circuit (13, 14) has an independent ventilation path (19, 19a) and at least one of the pressure control circuits (13, 14) has an independent redundancy control pressure path (21) and at least one other of the pressure control circuits (13, 14) comprises a device (16a) for forced venting in the event of a failure by means of the associated ventilation path (19a).

Description

technical field [0001] The invention relates to a brake pressure modulator for an electronic braking system of a commercial vehicle according to the preamble of claim 1 . Background technique [0002] The electronic braking system enables precisely metered and rapid braking of the vehicle. In this case, the output signal of the brake parameter transmitter is fed to the controller, which output signal depends on the driver's desire to decelerate. In the controller, the output signal of the brake parameter transmitter can also be modified by a driving safety system such as an anti-lock braking system, an acceleration anti-skid control or a system for a driving stability control device. The controller thus generates a control signal, which is passed to a so-called brake pressure modulator, which controls the pressure medium (compressed air in the case of commercial vehicles) via an electromagnetically actuatable valve arrangement Wheel-dependent or axle-by-axle supply to the ...
