Abstract
PURPOSE: In a multi-channel brake system, to alert the driver on car trouble in the event of insufficient hydraulic pressure in any channel of the system.
CONSTITUTION: Absence of sufficient hydraulic pressure on the upstream of a hydraulic pressure control device 100 preduces an excessive difference on pressure between conduits 13a and 13b, opens a pressure differential switch 13c, stops operation of a relay means R1, shuts off a circuit for computer 200, opens a circuit for a warning lamp L and lights a lamp L. Then, even if a driver stops his car and turns off an ignition switch 1, the lamp L remains lit, unless brake fluid is replenished or a manual switch M is intentionally actuated after recovery of fault, due to formation of a self-retention circuit by the relay means R1 and the switch H
