Engine knock recognition and calibration method and system, electronic equipment and storage medium

The invention provides an engine knock identification and calibration method and system, electronic equipment and a storage medium. The method comprises the following steps: acquiring vibration information of an engine cylinder, and acquiring a knock intensity factor according to the vibration information and a pre-constructed knock identification model; wherein the knock identification model comprises a knock intensity factor acquisition strategy and calibration parameters of the knock intensity factor acquisition strategy; the calibration parameter comprises a knock threshold value; and then whether the knock intensity factor exceeds a knock threshold value or not is judged, and if yes, the engine is knocked. Therefore, the engine knock identification and calibration method provided by the invention does not need special equipment and numerous wire harnesses matched with the special equipment during knock identification, so that the cost can be obviously saved; and the identification method is simple and ea
