Abstract

An electronic control device for a pressure controller, by way of which solenoid valves for pressure control are actuated with current via an actuating electronic system, and having a pump assembly is actuated as a function of a pressure request, which generates a volumetric flow with a periodically fluctuating amplitude. The wheel brake circuit isolating valve, during an active pressure build-up, discharging part of the delivery volume into a reservoir volume, at least in the case of a control operation which performs an intervention for driving stability which is not critical to safety, if the pressure which is built up by the assembly is higher than the pressure which is to be set, the electric coil current for the actuation of the isolating valve is modulated and the periodic actuation being interrupted at least when the control device has to carry out an intervention for driving stability which is critical to safety.
