Abstract

The invention relates to an electronically controllable pneumatic brake system (100), comprising: at least two brake circuits (A, B, C), wherein at least one of the at least two brake circuits (A, B,C) is assigned an electrically and pneumatically controllable control valve (11, 13) for specifying brake pressures (p1, p2, p3, p4, pPB) for controlling wheel brakes (1, 2, 3, 4) of the associated brake circuit (A, B, C); and a first control unit (110), which is designed to electrically control the control valve (11, 13) in question in accordance with a vehicle target deceleration (zSoll) requested in an automated manner or in accordance with an actuation (ds) specified by the driver by means of an actuation device (24a). According to the invention, at least one bypass valve (21) associated with a control valve (11, 13) is also provided, which bypass valve is designed to pneumatically (pA, pB) control the associated control valve (11, 13), wherein the pneumatic control (pA, pB) is performed in accordance with the vehicle target deceleration (zSoll) requested in an automated manner or in accordance with the actuation (ds) specified by the driver.

Description

technical field [0001] The invention relates to an electronically controllable braking system in a commercial vehicle, in particular an automatically controllable commercial vehicle, and to a method for electronically controlling a pneumatic braking system. Background technique [0002] In vehicles, in particular commercial vehicles, with a pneumatic braking system, in particular configured as an electronically operated braking system (EBS or ABS), electronically controlled valves (such as relay valves or axle modulator) to equip the brake pressure, the electronically controlled valve pneumatically directs the brake pressure to the brake cylinders of the service brakes of the brake system as a function of the required target deceleration of the vehicle. Equipping the brake pressure by means of the driver's actuation of the brake force regulator or brake value transmitter via the brake pedal is superimposed on the electronically equipped pneumatic brake pressure, so that the ...
