摘要:
The invention relates to a frequency generator assembly, comprising at least one oscillator (1) and an electronic signal processing device (2), which is designed in such a way that the electronic signal processing device provides an electric clock signal (f) having a defined frequency as an output signal of the frequency generator assembly, wherein said defined frequency depends on the vibration frequency of the oscillator (1), wherein the oscillator comprises at least one micromechanical seismic mass (11), which is vibrationally excited by means of at least one driving device (12), whereupon the electronic signal processing device (2) generates and provides the electric clock signal (f) according to the vibration frequency of the at least one seismic mass (11).
摘要:
The invention relates to a protective circuit for a controlling element (100) of an electrically controlled brake booster, comprising a first and a second line (103, 104), whereby two potentials feed the connections of the controlling element, a first electronically actuated switch (106, 206) provided in the first line (104), a control device (112, 235 - 237) switching the first switch with a first control signal (S1), preferably a pulse width modulated control signal, and a second electronically actuated switch (105, 205) provided in the second line (103), wherein the control switch switches the second switch with a second control signal (S2). The method for testing the protective circuit comprises a step wherein at least one potential on at least one connection of the controlling element is tested when both switches are opened.
