Abstract
A brake system for a motor vehicle comprises a hydraulic line system with at least one normally closed hydraulic valve, wherein a final stage is provided for electrically actuating the at least one hydraulic valve. To minimize noise emissions, the final stage is a final stage with analog control and a computing unit is provided which is configured to determine a valve current based on a pressure difference across the hydraulic valve and to actuate the final stage to make the valve current available at the hydraulic valve.

A brake system for a motor vehicle comprising:
- a hydraulic line system with at least one normally closed hydraulic valve;
- a final stage is provided for electrically actuating the at least one hydraulic valve, wherein the final stage is a final stage with analog control;
- and
- a computing unit is provided which is configured to determine a valve current based on a pressure difference across the hydraulic valve and to actuate the final stage to make the valve current available at the hydraulic valve.
A method for controlling a normally closed hydraulic valve in a brake system comprising:
- determining a valve current based on a pressure difference across a hydraulic valve;
- and
- providing the determined valve current with a final stage that has analog control.
