Embodiment Construction

[0067] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0068] Such as Figure 1 to Figure 3 Shown: In order to improve the efficiency of software development, enhance the reliability and portability of software, adopt the idea of ​​modularization, combined with the framework of embedded operating system, standardize the development of software. The whole software system is divided into three levels, such as figure 1 As shown, it is the hardware abstraction layer, the service layer and the application layer in turn.

[0069] The hardware abstraction layer is only related to the hardware of...

Abstract

The invention provides a whole vehicle signal analysis simulation system based on an ECU. The whole vehicle signal analysis simulation system comprises three layers including a hardware abstraction layer, a service layer and an application layer. The hardware abstraction layer comprises a clock module, a timer module, an IO module, an AD module, a CAN module, an SCI module and a PWM module, and isonly related to single-chip microcomputer hardware; the service layer comprises an interface module used for an interface between the hardware abstraction layer and the application layer; and the application layer comprises an input acquisition module, a gateway module, a CCP module and a signal simulation module, and is used for realizing specific functions. According to the whole vehicle signalanalysis simulation system, the software development efficiency can be improved, the reliability and transportability of software are enhanced, and the software is subjected to standardized development by adopting a modular thought and combining an embedded operating system framework.

Description

technical field [0001] The invention relates to the technical field of communication signal simulation, in particular to an ECU-based vehicle signal analysis and simulation system and a working method thereof. Background technique [0002] There are mainly two development methods in engine development, namely forward development and reverse development. One of the cores of engine forward development is the accumulation of product data. By accumulating various performance data of a large number of advanced engines in the industry, that is, benchmark machines, we can grasp the performance level and provide reference for the definition and decomposition of engine performance targets under development. Therefore, it is very important to obtain accurate performance data of the benchmarking machine. [0003] Benchmarking machines are usually disassembled from the entire vehicle, and then various expected performance data are obtained through engine bench tests. However, with th...
