DEVICE FOR PREVENTING SUDDEN ACCELERATION ACCIDENT OF VEHICLE

WIPO Patent Application WO/2018/012720

A1

The present invention relates to a device for preventing a sudden acceleration accident of a vehicle, wherein the device, which is electrically connected and provided between a fuel supply line and an ignition device of a vehicle, opens or closes the fuel supply line by moving according to the maintenance of a polarity, which is the same as or different from that of an electromagnet, by a permanent magnet in a valve body facing the electromagnet, the electromagnet operating by means of the supply and breaking of a current, so as to start or stop the vehicle. Therein, a plurality of guide walls are erected alongside the periphery of the permanent magnet in the valve body such that fuel passes between the permanent magnet and the guide wall having a predetermined gap therebetween, thereby enabling the almost complete prevention of sudden acceleration accidents by making the fuel flow smoothly before the accident prevention device is operated and by simply blocking the supply of the fuel if the engine revolutions per minute that would unexpectedly cause the sudden acceleration of the vehicle is reached.
