The embodiment of the invention relates to a processing method of an automatic driving longitudinal control calibration table. The method comprises the following steps: collecting a first original data group set; performing data preprocessing to generate a first training data group set; training a first accelerator pedal opening control model and calibrating a first longitudinal control calibration table; training a first mechanical brake pressure control model and calibrating a second longitudinal control calibration table; training a first brake pedal opening control model and calibrating a third longitudinal control calibration table; collecting a longitudinal real-time vehicle speed, a longitudinal expected acceleration and a control mode; when the control mode is the driving mode, estimating the opening degree of the accelerator pedal by referring to the longitudinal control calibration table; longitudinal driving control is carried out based on the estimation data; when the control mode is a braking mode, estimating mechanical braking pressure by referring to the longitudinal control calibration table; estimating the opening degree of the brake pedal by referring to the longitudinal control calibration table; and performing longitudinal braking control based on the estimated data. According to the invention, the automatic driving longitudinal control accuracy is improved.
