Engine torque model calibration method and engine torque model calibration system

Abstract

The invention provides an engine torque model calibration method and an engine torque model calibration system, wherein the engine torque model calibration method includes: acquiring the input speed and input torque of the engine; Output torque; generate the universal characteristic map of the engine according to the input speed, circulating oil volume and output torque; input the universal characteristic map of the engine to the output unit of the engine, and the output unit of the engine outputs the corresponding output according to the calibration data in the universal characteristic map of the engine For the calibration output torque of the external input torque, the technical solution is to automatically obtain the circulating oil volume and output torque, to avoid the collection of measurement data by the staff, and to automatically generate the universal characteristic map of the engine to save the workload of the staff and improve the performance. The accuracy of the engine's universal characteristic map ensures that the engine can accurately respond to the driver's driving requirements and improve the safety of the driving process.

Description

technical field [0001] The invention relates to the technical field of engine calibration, and more specifically, to an engine torque model calibration method and an engine torque model calibration system. Background technique [0002] The engine electronic control management system drives the internal fuel supply of the engine through the external torque demand, so as to control the mixing ratio of air and fuel in the engine cylinder, the combustion process and the conversion of exhaust gas. The engine selects the control parameters of the engine through the torque model, so as to correctly Respond to the driver's driving request. [0003] At present, the calibration of the torque system requires the staff to collect the universal characteristic values ​​of the engine, and the staff will draw the collected universal characteristic values ​​into a universal characteristic chart for the output unit of the engine to use according to the data in the universal characteristic cha...

Problems solved by technology

[0004] The manual drawing of the universal characteristic chart has a large workload, and it is difficult to improve production efficiency. Moreover, the manual drawing of the universal characteristic chart is difficult to ensure the accuracy of the data, and the torque model is prone to inaccuracy, so that the engine cannot accurately respond to the driver's demand. A driving requirement occurs
