Abstract
A device for controlling sudden unintended acceleration according to an embodiment of the present disclosure includes a sensor for detecting a current acceleration of a vehicle, a first controller that calculates a motor torque command value for driving a motor, calculates an expected acceleration of the vehicle based on the motor torque command value, and compares the expected acceleration with the current acceleration, and a second controller that compares the motor torque command value with a preset value. Therefore, the device may determine a cause of the sudden unintended acceleration and block the sudden unintended acceleration based on the determination result to improve safety of a driver.
