The invention discloses a system and a method for generating an automatic driving accelerator and brake calibration table. The method comprises the following steps: S1, filtering acquired vehicle data to obtain corresponding vehicle state data, and storing the corresponding vehicle state data in a buffer; and S2, inputting the vehicle state data in the buffer into the constructed calibration model, and generating an updated accelerator pedal calibration table. Through the calibration model constructed by the online learning module, the mapping relationship among the accelerator pedal, the speed, the pitch angle and the acceleration can be more accurately obtained; meanwhile, the manufacturing of the accelerator/brake pedal calibration table does not need tedious manual operation, so that the efficiency is improved; meanwhile, an algorithm is learned online through a calibration table, longitudinal accurate control can be guaranteed even along with changes of the environment and the load, the control robustness is improved, and the driving experience is improved.
