Accelerator pedal opening degree auxiliary control device and method

The invention relates to the field of automobile accelerator pedals, in particular to an accelerator pedal opening degree auxiliary control device and method. When a vehicle is tested, the device is fixed at a specified position below an accelerator pedal; and then, the adjusting plate can be fixed at a preset height through cooperation of the air cylinder, the piston, the piston connecting rod and the main body support. In this way, the pressing position of the accelerator pedal is limited, and then the opening degree of stepping on the accelerator pedal every time is kept consistent; and then through the characteristic that the first cavity is communicated with the second cavity, resetting of the air cylinder is achieved according to the air pressure principle. The distance sensor is arranged to measure the distance between the bottom of the air cylinder and the bottom of the main body support in real time, and the programmable controller is used for processing data and controlling the hydraulic lifting rod
