Description

A kind of automobile controller rapid prototyping implementation method

Technical field

The present invention relates to vehicle electric field, more particularly, to using S-function in automobile controller development process The method for realizing the controller rapid prototyping (RCP) on particular platform.

Background technology

In automobile controller development process, under MATLAB environment to algorithm floating-point mould fixed point after the completion of, utilize Automatic Code Generation (Real Time Workshop, RTW) in MATLAB softwares is to model real time workshop, then The code automatically generated is downloaded on target platform after carrying out integrated compiling with system software, reaches Product rapid realization checking The purpose of purpose, i.e. rapid prototyping (RCP).

Because during actual development, different projects may use identical target platform, and this requires one kind The method of rapid multiplexing bottom code, to shorten the project cycle and development cost.The traditional method for realizing rapid prototyping and Deficiency mainly has：

1. the target platform storehouse carried using MATLAB.Due to the finiteness of object library, it can undoubtedly make the choosing of target platform Select and be restricted, and object library is also required to charge purchase in itself, so also brings along the increase of cost；

2. hand-written bottom code.So it is accomplished by putting into manpower, also brings along the increase of the project cycle and cost.And by In the difference of project in itself, though bottom code is multiplexed, but the configuration of bottom may be not consistent, is so accomplished by reconfiguring And debugging, so also bring along the increase of the project cycle.

The content of the invention

Present invention aim to address in automobile controller development process, traditional controller rapid prototyping is to target Therefrom is more, the problem of automation and reusing degree are relatively low.

In order to achieve the above object, a kind of automobile controller rapid prototyping implementation method of the invention, it is characterized in that including： During rapid prototyping (RCP), bottom layer driving is packaged, the form that bottom layer driving is packaged into module is added to Simulink storehouses can just be directly invoked in a model, model be directly generated into source code using MATLAB RTW instruments, accordingly MCU driving module can also generate source code, so as to avoid hand-written driving code, and directly use model, make exploitation more square Just, multiplexing can also be realized in disparity items, so as to save more resources, is mainly included：

(1) bottom layer driving is packaged using S-function in MATLAB and Mask；

(2) Block TLC files are write.

Above-mentioned specific method is：

(1) Mask encapsulation is carried out to bottom layer driving：

1. the S-function modules in Simulink storehouses are used, double-clicks and S-function names is write after opening, such as Msp430f2132_di, this document is s-function C files, can define the input/output port including module, port The parameter of type, S-function parameters are RTDParameters；

2. the encapsulation of gui interface, i.e. Mask, S- are carried out according to S-function parameters number Function Mask needs click right to select Mask S-Function to enter edlin, in this module, has four Output port, type is checkbox, and when some checkbox is in selected state, output end eloquence is effective；

3. User Interface envelope turns initializtion script in Initialization, uses m language,

(2) write mutual between corresponding S-function files, Simulink and C MEX S-Function Effect is by calling the call back function in S-Function to realize；Each function completes a pre-defined task, Necessary to these tasks are the simulation block functions that S-Function is defined；

(3) Block TLC file edits：

After the s-function and mask of drive module, write the TLC files of module to carry out code building；

So far, the writing of drive module, mask encapsulation, TLC file edits are just completed, and can just be downloaded the code of generation Rapid prototyping is carried out on to hardware platform to test.

After the present invention, the bottom layer driving to platform under MATLAB environment is packaged, and writes corresponding Block TLC files, thus can be with so that the module of encapsulation is directly used in modeling developing, it is possible to automatically generate bottom layer driving code Hand-written driving code is avoided, and platform is had more preferable durability, makes controller rapid prototyping (RCP) more convenient, So as to save project cost and construction cycle.

Brief description of the drawings

Fig. 1 is the path block diagram of automobile controller rapid prototyping implementation method.

Embodiment

Below in conjunction with the accompanying drawings and the invention will be further described by embodiment.

During rapid prototyping (RCP), bottom layer driving is packaged, such as the input and output of single-chip microcomputer, AD, serial ports Deng driving the form for being packaged into module to be added to simulink storehouses and can just directly invoke in a model such, utilize Model is directly generated source code by MATLAB RTW instruments, and corresponding MCU driving module can also generate source code, thus Hand-written driving code can be avoided, and directly uses model, exploitation is more convenient, multiplexing can also be realized in disparity items, So as to save more resources, mainly include：

1. bottom layer driving is packaged using S-function in MATLAB and Mask；

2. write Block TLC files.

Here is to utilize above-mentioned automobile controller rapid prototyping implementation method, to the writing of drive module, mask encapsulation, It is illustrated exemplified by TLC file edits, it is successively：

1. pair bottom layer driving carries out the encapsulation of Mask encapsulation, such as single-chip microcomputer MSP430F2132DI modules：

1. the S-function modules in Simulink storehouses are used, double-clicks and S-function names is write after opening, such as Msp430f2132_di, this document is s-function C files, is capable of input/output port, the port type of definition module Etc. parameter, S-function parameters are RTDParameters；

2. the encapsulation of gui interface, i.e. Mask are carried out according to S-function parameters number.S- Function Mask needs click right to select Mask S-Function to enter edlin, in this module, has four Output port, type is checkbox, and when some checkbox is in selected state, output end eloquence is effective；

3. User Interface envelope turns initializtion script in Initialization, uses m language

(2) write mutual between corresponding S-function files, Simulink and C MEX S-Function Effect is by calling the call back function in S-Function to realize；Each function completes a pre-defined task, Necessary to these tasks are the simulation block functions that S-Function is defined；One C MEX S-function general format is such as Under：

#define S_FUNCTION_NAME your_sfunction_name_here

#define S_FUNCTION_LEVEL 2

#include"simstruc.h"

static void mdlInitializeSizes(SimStruct*S)

{

}

static void mdlTerminate(SimStruct*S)

{

}

#ifdef MATLAB_MEX_FILE/*This is file being compiled as a MEX-file*/

#include"simulink.c"/*MEX-file interface mechanism*/

#else

#include"cg_sfun.h"/*Code generation registration function*/

#endif

When Simulink and S-function interacts, the first program that Simulink is called is

MdlInitializeSizes, what is then called is that (all function names are with mdl for other S-function functions Beginning)；

At the end of emulation, Simulink calls mdlTerminate functions；

3.Block TLC file edits：

After the s-function and mask of drive module, it is possible to write the tlc files of module to carry out code building , it is as follows：
