Title: Apparatus and method of preventing sudden acceleration of vehicle

Abstract: An apparatus and method is provided for preventing sudden acceleration of a vehicle having an automatic transmission by detecting the sudden acceleration with use of transmission state information and rpm. A controller determines that sudden acceleration occurs if the rpm abruptly increases within a first reference time when the transmission maintains a stop or park state, output voltage of an accelerator pedal detected by an ACC detecting unit is less than a predetermined level after inputting a start key. In addition, the controller determines the sudden acceleration if the transmission changes to a driving state and the rpm abruptly increases within a second reference time. When the vehicle drives at a high speed, the controller detects sudden acceleration only when the transmission changes by repeatedly counting the rpm. The controller may also be a central processor unit in an engine control unit of the vehicle. Such apparatus and method may brake the vehicle in case of sudden acceleration, so as to prevent an accident caused by the sudden acceleration.
