Fuel bus model and building method thereof

Abstract

The invention provides a fuel bus model and a building method thereof. The fuel bus model comprises a first system and a second system; the first system comprises a first subsystem and a second subsystem; the second system comprises a first subsystem and a third subsystem; the first system activates the first subsystem and the second subsystem which are included in the first system; the second system activates the first subsystem and the third subsystem which are included in the second system; the first subsystems comprise first module groups capable of being shared by the first system and thesecond system; the second subsystem comprises a second module group supporting an independent algorithm rule; and the third subsystem comprises a third module group supporting a general algorithm rule. Shared modules exist in the base subsystems, while modules used for achieving special functions exist in the corresponding subsystems. During actual use, the complete model of different structuresfor different functions can be quickly obtained only by selecting the different systems.

Description

technical field [0001] The invention relates to the technical field of modeling of a fuel passenger car, in particular to a model of a fuel passenger car and a building method thereof. Background technique [0002] When building a traditional power bus model that matches a manual gearbox, it is necessary to set the shift rules of the manual gearbox, especially when calculating according to the comprehensive working conditions, it is very important to set the shift rules. [0003] At present, when building a traditional power bus model, the shift rules can be directly set in the calculation task, which does not involve the change of the model structure. The shift rules in the calculation task include: 1. Shift based on vehicle speed; 2. Shift based on engine speed 3. Shift gears based on the preset shift points in the map. [0004] When determining to meet the fuel consumption limit in the national standard GB 30510-2018, it is stipulated that the passenger car should be tes...

AI Technical Summary

Problems solved by technology

Because the two sets of models have different structures and data signal connections, the models cannot be used universally. To switch gear shift rules, the model structure, signal connection, and calculation task settings must be changed, which is time-consuming, laborious and error-prone.
