DEVICE FOR CONTROLLING HYDRAULIC PRESSURE COMPENSATION IN STOPPING ENGINE OF VEHICLE

摘要

PURPOSE: A hydraulic pressure compensation control device in stopping an engine of a vehicle is provided to decrease braking distance normally by securing braking force with compensating absence of negative pressure to a brake booster in detecting the engine stall during traveling. CONSTITUTION: A hydraulic pressure compensation control device comprises an air compressor(12) generating high pressure air by receiving remaining power from an engine(10) at engine stall during traveling; a power train clutch(16) connecting the engine and the air compressor by a power train shaft(14) to transmit power from the engine at engine stall; a pneumatic passage(18) applying pneumatic pressure from the air compressor to a brake master; a check valve(20) installed in the pneumatic passage to apply high pressure air from the air compressor to the brake master; and a control unit generating high pressure air from the air compressor by operating the power train clutch in detecting engine stall during traveling.
