DEVICE FOR PREVENTING RUNAWAY ACCIDENT DUE TO WRONG DEPRESSION EXCESSIVE OPERATION BETWEEN ACCELERATOR AND BRAKE

摘要

PROBLEM TO BE SOLVED: To prevent a runaway accident when a driver wrongly depresses an accelerator instead of a brake, during stopping a vehicle.;SOLUTION: When a shaft of an A-cylinder joined to an accelerator pedal is depressed normally, the A-cylinder moves forward slowly to push oil from a hole of 3 mm. A C-cylinder moves forward slowly to apply a force to an accelerator, thereby increasing a speed. When the accelerator is released, the A- and C-cylinders are returned, the accelerator is returned, and the speed is reduced. When the accelerator is abruptly depressed strongly, the hydraulic pressure generated by the A-cylinder opens an A-valve, to push out the B-cylinder, and a brake is actuated.;COPYRIGHT: (C)2013,JPO&INPIT
