MALFUNCTION SENSING LOGIC FOR CHANGING POWER OF AN ACCELERATION PEDAL SENSOR CAPABLE OF PREVENTING THE QUICK START OF A VEHICLE

摘要

PURPOSE: A malfunction sensing logic for changing power of an acceleration pedal sensor is provided to control engine operation according to the change of power by sensing the change rate of a engine RPM(Revolution Per Minute) and a location.;CONSTITUTION: When a measured RPM change rate is over a reference RPM change rate, a malfunction sensing unit(110) outputs a malfunction signal. A malfunction determination unit(120) determines the malfunction of an accelerator pedal sensor when the malfunction signal is received. When the accelerator pedal sensor is broken, a control unit(130) stores a malfunction code. The control unit prevents the SUA(Sudden Unintended Acceleration) of a vehicle.;COPYRIGHT KIPO 2012
