Title:
PRESSURE MONITOR DEVICE FOR AUXILIARY ENERGY SOURCE OF SLIP CONTROL BRAKE SYSTEM OF AUTOMOBILE
Document Type and Number:
Japanese Patent JPS60255561
Kind Code:
A
Abstract:
An apparatus for monitoring the pressure of an auxiliary energy source (10, 11, 12) of a slip-controlled brake system for motor vehicles comprises at least two switches responding when falling below a pressure limit value(p1), releasing warning signals and influencing the function of the brake slip control. Through logical operation of the switch functions, failure of a switch (ws1, ws2) will be detected and an error signal derivable therefrom resulting in the partial shut-down or cut-off of the control. The monitoring circuit responds to two different pressure limit values (po, pu). The brake system is partially shut down or cut off by measuring the interval ( DELTA T) between the response to the upper and lower pressure limit threshold (po and pu, respectively), locking and then switching on the master valves (21, 22), detecting the reaction on turning on again the master valves etc., and by logical operation of the signals.
