Problems solved by technology

[0002] The development of ECU software mostly adopts model-based design. Simulink is one of the most commonly used modeling tools. Currently, the execution of the model is mainly time-based scheduling. Even with segment scheduling, it only implements a simple 180-degree call once. , did not refine the tasks, there are shortcomings such as poor versatility, low task trigger accuracy, and a large difference between the scheduling method and the actual operation mechanism of the model, resulting in inaccurate and insufficient model integration testing
In addition, if the integrated model changes, the trigger source will also change, and the trigger signal will change a lot, which is time-consuming and labor-intensive

Embodiment Construction

[0035] The invention converts the engine speed into an angle step (accuracy is determined by the system simulation time), simulates the crankshaft angle (0 to 720 degrees) through angle accumulation, and judges whether the corresponding angle is reached by comparing with the target angle, thereby triggering the corresponding angle task ( S0 or S1), time tasks are implemented through counters, and task triggers are used to implement the scheduling of the integrated model. It is mainly composed of basic parameter input module, task trigger (angle step calculator, angle accumulator, task trigger module), task function list, task assignment module and integrated model, figure 1 In , the dotted box indicates other links of ECU software development, which are not within the scope of the present invention. The fully tested model will be integrated with the basic software, and the final code will be downloaded to the ECU.

Abstract

The invention relates to a model integration dispatching system. The model integration dispatching system comprises a basic parameter input module, a task trigger, a task allocation module and an integrated model which are sequentially connected with one another, wherein the task trigger is internally provided with an angle step size calculator, an angle accumulator and a task triggering module which are sequentially connected with one another; the integrated model is internally provided with a plurality of task function modules; the task trigger is provided with a task function list; task function names in the task function list are in one-to-one correspondence with task function modules in the integrated model. Tasks triggered by the system comprise an initialization task, an angle task and a time task, and the accuracy of the task trigger can be adjusted; compared with a traditional model integration dispatching system, the model integration dispatching system provided by the invention is more comprehensive in task triggering types, higher in universality and higher in task triggering accuracy.

Description

technical field [0001] The invention relates to a model integrated scheduling system of an engine electronic control unit (ECU), belonging to the technical field of engines. Background technique [0002] The development of ECU software mostly adopts model-based design. Simulink is one of the most commonly used modeling tools. Currently, the execution of the model is mainly time-based scheduling. Even with segment scheduling, it only implements a simple 180-degree call once. , did not refine the tasks, there are shortcomings such as poor versatility, low task triggering accuracy, and a large difference between the scheduling method and the actual operating mechanism of the model, resulting in inaccurate and insufficient model integration testing. In addition, if the integrated model changes, the trigger source will also change, and the trigger signal will change greatly, which is time-consuming and labor-intensive. Contents of the invention [0003] The purpose of the pres...
