A control system for preventing sudden acceleration of a vehicle is provided. The system includes a sensor unit that detects engine RPM of a vehicle, a speed, a depressed state of an accelerator pedal, a depressed state of a brake pedal, and vacuum pressure of a brake booster. A hydraulic pressure compensation unit compensates hydraulic pressure of a brake and a controller determines whether the vehicle is suddenly accelerated based on at least one or more items of information of the engine RPM of the vehicle, the speed, the depressed state of the accelerator pedal, and the depressed state of the brake pedal detected by the sensor unit. The controller then compensates braking force of the brake by generating hydraulic pressure through the hydraulic pressure compensation unit when the vehicle is suddenly accelerated.
