Engine speed regulation device and method based on automatic control of accelerator pedal

The present invention provides an engine speed regulation device and method based on automatic control of an accelerator pedal. The device comprises a control system arranged at the external portion of a vehicle to be measured and an execution mechanism arranged at the internal portion of the vehicle to be measured and connected with the control system, an industrial control computer is provided with a detection program to set a target value R of the engine speed and read an engine speed Ri, a servo amplifier controls a servo motor, the servo motor controls an accelerator pedal to regulate theaccelerator pedal of the vehicle, when the current value Ri of the engine speed is smaller than R, the servo motor is controlled to perform anticlockwise rotation; and when the current value R1 of the engine speed is larger than R, the servo motor is controlled to perform clockwise rotation, a data collection processor is employed to continuously read the engine speed to perform information feedback and circularly regula
