Embodiment approach 1
[0146] This embodiment provides an implementation of step 602 to solve the above problem, which is applied to the case where the target calibration data includes table variables, such as Figure 7 As shown, implementation mode 1 of step 602 of this embodiment may include:
[0147] Step 701, judging whether the table dimensions of all table variables in the target calibration data before and after conversion are the same; if yes, enter step 702, if not, enter step 703;
[0148] Among them, before step 701, in the conversion process of step 105, record whether the table dimension of each variable is the same before and after the conversion, so that whether there is a variable whose table dimension is inconsistent before and after the record is judged .
[0149] Step 702, generate the target actual storage value into a binary code data file of the target engine under the second electronic control system;
[0150] Step 703: Generate the target actual storage value into a target ...

The invention discloses a method of calibration data transformation in engine electronic control systems. An initial engine is respectively calibrated in a first electronic control system and a second electronic control system, so that first calibration data and second calibration data are obtained. Corresponding relation between the first calibration data and the second calibration data is established and is identified as a true value transformational rule. The method includes that according to obtained original calibration data of a target engine under the first electronic control system, an original true physical value of the original calibration data is obtained, and according to the true value transformational rule, the original true physical value is transformed into a target true physical value. According to the target true physical value, target calibration data of the target engine under the second electronic system is generated. By utilization of the technical scheme, the situation that each engine with a same system upgrade is recalibrated is avoided so that resources and time consumed are saved.
Description
technical field [0001] The invention relates to the field of engine electronic control, in particular to a method and device for converting calibration data in an engine electronic control system. Background technique [0002] In the control logic of the engine electronic control system, the calculation process of many calculation results needs to use some constant variables and the corresponding relationship between one-dimensional or two-dimensional variables. Changes in these variables will lead to changes in the calculation results of the control logic, which in turn will cause changes in various operating state indicators of the engine. As for the engines of different products, due to the different performance and functions of the products, the values required by these variables in the electronic control systems of different products are mostly different. Therefore, in order to make the control logic of the electronic control system meet the functional requirements o...
