1. A device for preventing sudden unintended acceleration, the device comprising: a driving information collector configured to collect information, including a vehicle brake signal, a vehicle speed, an engine revolution per minute (rpm), a turbine rpm, and an accelerator pedal position;a vehicle characteristic storage configured to store data, including a vehicle's weight, and a characteristic curve of a torque converter;a brake sensor connected with the driving information collector and configured to sense the vehicle brake signal;an accelerator pedal position sensor connected with the driving information collector and configured to sense the accelerator pedal position; anda controller configured to calculate the difference between a total fuel consumption amount and a learned or stored fuel consumption amount based on the information and data,wherein the total fuel consumption amount includes at least one of a fuel consumption amount or a transmission slip work loss and a fuel consumption amount for an accelerating resistance work loss,wherein the controller is configured to determine whether a vehicle is in a sudden unintended acceleration state based on:(1) the difference between a total fuel consumption amount and a learned or stored fuel consumption amount;(2) whether a brake signal is ON; and(3) whether an accelerator pedal position is in an initial position and the vehicle is not in an auto cruise mode, andwherein the controller initiates an action when the vehicle is determined to be in the sudden unintended acceleration state. 2. The device of claim 1, wherein said action comprises actuating a switch configured to block an input power of an electronic throttle motor of the vehicle based on a determination by the controller that the vehicle is in the sudden unintended acceleration state. 3. The device of claim 1, wherein said action comprises actuating a switch configured to limit an engine power through control of an engine controller of the vehicle based on a determination by the controller that the vehicle is in the sudden unintended acceleration state. 4. The device of claim 1, wherein said action comprises actuating a switch configured to warn of the sudden unintended acceleration state based on a determination by the controller that the vehicle is in the sudden unintended acceleration state. 5. The device of claim 1, wherein said action comprises actuating a switch configured to inform of measures thereof audibly or through a display based on a determination by the controller that the vehicle is in the sudden unintended acceleration state. 6. A device for preventing sudden unintended acceleration, the device comprising: a driving information collector configured to collect information, including a vehicle brake signal, a vehicle speed, an engine revolution per minute, a turbine rpm, and an accelerator pedal position;a vehicle characteristic storage configured to store data, including a vehicle's weight, a transmission characteristic curve (C-factor curve), a torque ratio curve of the torque converter;a brake sensor connected with the driving information collector and configured to sense the vehicle brake signal;an accelerator pedal position sensor connected with the driving information collector and configured to sense the accelerator pedal position; anda controller configured to determine whether a vehicle is in a sudden unintended acceleration state based on:(1) the calculation of difference between a total fuel consumption amount and a learned or stored fuel consumption amount based on the information and data;(2) whether the brake signal is ON; and(3) whether an accelerator pedal position is initial position and the vehicle is not in the auto cruise mode,wherein the total fuel consumption amount includes at least one of the fuel consumption amounts for a transmission slip work loss and an accelerating resistance work loss, andwherein the controller initiates an action when the vehicle is determined to be in the sudden unintended acceleration state. 7. The device of claim 6, wherein said action comprises actuating a switch configured to block an input power of an electronic throttle motor of the vehicle based on a determination by the controller that the vehicle is in the sudden unintended acceleration state. 8. The device of claim 6, wherein said action comprises actuating a switch configured to limit an engine power through control of an engine controller of the vehicle based on a determination by the controller that the vehicle is in the sudden unintended acceleration state. 9. The device of claim 6, wherein said action comprises actuating a switch configured to warn of the sudden unintended acceleration state based on a determination by the controller that the vehicle is in the sudden unintended acceleration state. 10. The device of claim 6, wherein said action comprises actuating a switch configured to inform of measures thereof audibly or through a display based on a determination by the controller that the vehicle is in the sudden unintended acceleration state. 11. A device for preventing sudden unintended acceleration, the device comprising: a driving information collector configured to collect information, including a vehicle brake signal, a vehicle speed, an engine revolution per minute, a turbine rpm, and an accelerator pedal position;a vehicle characteristic storage configured to store data, including a vehicle's weight, a transmission characteristic curve (C-factor curve), a torque ratio curve of the torque converter;a brake sensor connected with the driving information collector and configured to sense the vehicle brake signal;an accelerator pedal position sensor connected with the driving information collector and configured to sense the accelerator pedal position; anda controller configured to determine whether a vehicle is in a sudden unintended acceleration state based on:(1) the calculation of a difference between a total fuel consumption amount and a learned or stored fuel consumption amount based on the information and the data; and the determination of whether the brake signal is ON, or(2) the calculation of a difference between the total fuel consumption amount and the learned or stored fuel consumption amount based on the information and the data; and whether the accelerator pedal position is initial position and the vehicle is not in the auto cruise mode,wherein the total fuel consumption amount includes at least one of the fuel consumption amounts for a transmission slip work loss and an accelerating resistance work loss, andwherein the controller initiates an action when the vehicle is determined to be in the sudden unintended acceleration state. 12. The device of claim 11, wherein said action comprises actuating a switch configured to block an input power of an electronic throttle motor of the vehicle based on a determination by the controller that the vehicle is in the sudden unintended acceleration state. 13. The device of claim 11, wherein said action comprises actuating a switch configured to limit an engine power through control of an engine controller of the vehicle based on a determination by the controller that the vehicle is in the sudden unintended acceleration state. 14. The device of claim 11, wherein said action comprises actuating a switch configured to warn of the sudden unintended acceleration state based on a determination by the controller that the vehicle is in the sudden unintended acceleration state. 15. The device of claim 11, wherein said action comprises actuating a switch configured to inform of measures thereof audibly or through a display based on a determination by the controller that the vehicle is in the sudden unintended acceleration state.
