发明名称 Tractor-trailer fluid pressure brake monitoring system
摘要 The invention provides a trailer brake monitoring system in which foot brake applications for normal braking and hand control braking for selectively applying the trailer brakes are separately monitored by respective monitoring switch circuits. Signals from the monitoring circuits are processed so as to provide a record of the duration and the count of such applications thus providing a record of the manner of brake usage. A solenoid-operated security system which can be locked and unlocked by a key is interconnected with the fluid supply to the trailer brakes.
