  • analogized electromagnetic valves It is known to design these valves as “analogized electromagnetic valves".
  • analogized electromagnetic valves is to be understood here and in the following as electromagnetic valves which assume a certain switching position by actuation with a certain control current for the purpose of setting a certain volume flow of hydraulic fluid
  • valve can also assume intermediate positions by a corresponding control between a (fully) open position and a (fully) closed position and thus at least approximately a defined position
  • a current regulator is required to control the electronically controllable valves, which reliably sets the desired current. In the event of a fault in the current regulator, setting the desired brake pressure is no longer guaranteed.
  • the current regulator is tested by activation with a test current which is so low that there is essentially no valve movement of the electronically controllable valve, so that there is essentially no hydraulic effect on the system of the vehicle brake system.

Accordingly, a pressure limitation function which is necessary for the brake system and has hitherto been implemented using special mechanical / hydraulic means is advantageously implemented by the analogized isolating valve, which enables a more compact design and component reduction.
  • the coils of the analogized valves are energized to a maximum so that they open when the specified pressure limit is reached.
  • the vehicle brake system then preferably does not have a mechanical / hydraulic pressure limiter. Switching off the regulator in the event of a fault can prevent the regulator from setting an excessive current, as a result of which a pressure-limiting function would no longer be ensured.
