A function calibration system and function calibration method for diesel engine electronic control data

Abstract

The invention discloses an electronic control data function collation system and an electronic control data function collation method for a diesel engine. According to the system, a standard function edition module creates, edits, configures and stores a standard function file; a data resolution module is used for resolving collated variable information in electronic control calibration data; a function collation module imports a collated variable from the data resolution module, imports the standard function file from the standard function edition module for collation, and transmits a collation result to a collation report generation module; and the collation report generation module generates and displays a collation report. The method comprises the following steps that: the standard function edition module creates, edits and configures the standard function file; the data resolution module resolves the collated variable information in the electronic control calibration data; the function collation module performs global function collation on a collated function, and transmits the collation result to the collation report generation module; and the collation report generation module generates and displays the collation report.

Description

technical field [0001] The invention relates to the field of electronically controlled diesel engines, in particular to a diesel engine electric control data function proofreading system and a function proofreading method. Background technique [0002] An electronically controlled diesel engine is an engine that controls conditions such as fuel injection quantity and fuel injection time through an electronic control unit. The electronically controlled diesel engine takes the engine speed and load as the basic signals reflecting the actual working conditions of the diesel engine, and determines the basic fuel injection quantity and injection timing map by referring to the fuel injection quantity and fuel injection timing map corresponding to each working condition of the engine obtained from the test. Oil time, etc., and then make various compensations according to various factors (such as water temperature, ambient temperature, atmospheric pressure, etc.) to obtain the best ...

Problems solved by technology

[0007] When correcting the function of a diesel engine, the same control function involves many variable information, mainly through the engineer subjectively selecting one or several representative variable information according to the external conditions, and through a large amount of data in the variable information. Simple calculation requires a lot of work, but only one-sided proofreading of the control function can be done based on experience, and the control problems caused by some unchecked variable information cannot be checked out, and the proofreading results of the obtained control functions have no global reference; if you choose All the variable information involved involves a lot of data, the logic operation is very complicated, the operability is poor, manual calculation is prone to errors, and the availability of calibration data is reduced;

[0008] Secondly, the functional proofreading mainly depends on the long-term accumulated experience of the proofreading engineers, and independently selects some data variables for functional proofreading, relying on experience to generally judge whether the proofreading results are reasonable, which cannot be separated from the subjective initiative of experienced engineers, and there is no inheritance. Ordinary employees cannot Perform proofreading work, proofreading work cannot be promoted;

[0009] Thirdly, due to the different functions of each engineer, it is impossible to be familiar with all the control function modules. Multiple engineers need to cooperate to complete the calibration of control functions. If the division of labor is not clear, there will be cases of missed calibration and re-calibration
