Title:
METHOD AND SYSTEM FOR CONTROLLING EXHAUST GAS EMISSION OF VEHICLE, AND ELECTRONIC APPARATUS AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/109236
Kind Code:
A1
Abstract:
Provided in the present invention are a method and system for controlling exhaust gas emission of a vehicle, and an electronic apparatus and a medium. The method comprises: acquiring a pedal curve corresponding to the current driving mode, a transmission line, and an optimal original emission region of an engine, and calculating a required power of the optimal original emission region, wherein the optimal original emission region is a set of original emission data that meets a preset condition; respectively calibrating the pedal curve and the transmission line according to the required power of the optimal original emission region, so as to obtain a torque value of the pedal curve and a transmission ratio of the transmission line; and controlling a vehicle by means of the torque value and the transmission ratio, so as to complete exhaust gas emission control of the current driving mode. The present invention effectively reduces the number of resources required for performing a large amount of calibration and testing of exhaust gas emission control in different driving modes, improves the emission control efficiency, reduces the development difficulty, and reduces the development cost and shortens the development cycle.
