Abstract: A cable modeling method and system, and an electronic device are provided. The method includes: acquiring preset cable attributes of a cable and a preset laying scenario of the cable; determining a start point, an end point and a path point of the cable according to the preset laying scenario; inputting the preset attributes of the cable, the start point, the end point, and the path point into an Autodesk Revit software to model the cable, thereby to obtain a cable simulation model; and laying the cable according to the cable simulation model. The method first determines a start point, an end point, and the path point of the cable through the preset laying scenario, and then inputs the preset attributes, the start point, the end point, and the path point into the Autodesk Revit software to model the cable, so as to obtain a cable simulation model.

Abstract: The present invention provides an engine control method, which comprises: receiving an indication of the pedal position; pre-processing the indication of the pedal position to determine whether the received indication of the pedal position corresponds to the antisurge mode activation condition; in response to the received indication of the pedal position corresponding to the antisurge mode activation condition, using the boost pressure and the engine speed to look up the static control parameter lookup table to select a control parameter indicating an air flow requirement; and sending the selected control parameter to the ECU so as to control the engine using the air flow requirement indicated by said control parameter.

Abstract: The present invention provides an engine control method, for each duty cycle of the engine, said method comprises: receiving a boost pressure of an engine turbocharger; receiving an engine speed; looking up a static control parameter lookup table according to the engine speed and boost pressure so as to select a control parameter indicating the air flow requirement; and sending the selected control parameter to an engine control unit so as to control the engine using the air flow requirement indicated by said control parameter.
