Functional inspection method of electromechanical filling level monitoring mechanism

摘要

PROBLEM TO BE SOLVED: To provide a method for performing a functional inspection of an electromechanical filling level monitoring mechanism (222). SOLUTION: In order to inspect a signal output from a filling level monitoring mechanism (222) of a first pressure medium chamber (214) for its reliability, a forced operation of the filling level monitoring mechanism (222) is occasionally performed. It is suggested to do. According to the present invention, this forced operation is performed by activating the pressure medium transfer unit (234) in the pressure medium circuit (232) having the first pressure medium chamber (214) for a predetermined time. .. The pressure medium transfer unit connects the pressure medium through the pressure medium coupling portion (232) to the first pressure medium chamber (214) to the second pressure medium chamber (214) provided with the filling level detection mechanism (222). 216) Transport to the inside. Based on the signal transition output from the filling level monitoring mechanism (222), the functional reliability of the filling level monitoring mechanism (222) is estimated in the electronic controller (230).
