Project 1 (Mini Project on Vehicle Direction Detection

Ans:'

OBSERVATION::

Here seen the Question of this mini-project what they are in  Mini Project on Vehicle Direction Detection

Mini Project - Vehicle Direction Determination General Overview:Objective of Mini Project:

in this project over view what they ask  and given precautions rules should be follow

in this they have given full information of wheel steering ,signals calibrations we should take precautions as per guidelines  and as given requirements 1,2,& 3  should be careful of each requirements as doing project

EXPLAINATION ::

first creating sldd File:

 

First go to matlab and open simulink next go to blank model 

1.To create a sldd file  after that go to model explorer and click the link to the data dictionary select see the below figure

1 is modeling tab there is a slide bar to open and click link to data dictionary

there is open a dialogue box see the below in this it is already created then go to browse setting , or create a new one then select new and create a SLDD File 

create a name Vehicle_direction_sldd file and save

inthis project we have create a path  /Add to path because we have save the files in order to a folder to files in one order way .

See the below we creating A SLDD file after saving like this:

 

CREATING SLDD FILE:

SEE the below figuare we can understood

1. here create the Signals and calibration of data sets

2. create as a manual type add signals one by one here 

here given in INPUT signal given a chart  import extern

                OUTPUT signal is export extern

calibration = Add constant option in tool bar (simulink parameter)  here and give the values in this chart as well other properties

 

 

in this given signal and calibration chart  4 signals and 6 constant  in SlDD file

NEXT SAVE THE SLDD FILE SHOWN IN BELOW FIGURE

 

NEXT WE HAVE GO TO MODEL REQUIREMENTS 1,2&3

here first go to file and add subsystems  and add another two subsystems First subsystem is requirement 1 purposes and second one is requirement 2 purposes

see the subsystem design :

Here see the main subsystem for vehicle direction 

 

 

here see the inner they have two subsystems is there for requirement 1 and 2nd subsystem is used for requirement2 see the below figure we can easily understood

here adding one inport is added to requirement and another in port is added to another requirement2  block .And first requirement1 block output to added second requirement subsystem 2 finally one output port of these two subsystem requirements blocks:

here given signal namees and port names should copy and paste these names because we cant required errors and those no missing any signal names

 

in this we have a required to show the block of subsystem for requirement 1 

see here we shown subsystem of requirement1

 

 

Explaination:

here switch condition NAB guidelines because we are given to threshold is notequal to zero u2~=0 because we are going to model advisior check

there is showing an error thats y im using switch condition threshold is not equal to zero

here your giving any positive value it goes to 1 True .  it goes to output. If given  value its equal to zero its go to false  it goes to another switch

here comparision of logical switch compare to conditionsand given value steeringwheel_yawDegree input is comparision conditions here it is the value irst condition is greater than zero '>0' it goes to switch value 1 it goes to output not equal to zero its goes and again switch operation will be there these condition apply as ' ==0' its go to 

 

+1 degree to 180 degree vehicle is go to right turn angular limit

its`~>0  it will be false switch is connected to another switch here

condition is ==0 the straight _Drive_steeribng_angle its go to switch and its applicable

if here these two condition is false its go to third condition Left_Turn_Angularlimit send to the output

 

Here REQUIREMENT2:

first Requirement1  output is connected to Requirement 2

 

here the circuit shows  vehicle turn status again here three  component values they are 1.Rightturn_Road sign,2.Leftturn_Road sign,and3.Straight_Roadsign

here the vehicle turn right the value =30

its left turn its value=-120

and=0 its go to straight condition 

here again relational operates =1 and it goes And gate camera input also 1 its go to  shows to right

2.here similarly other two sign roads also straight and left condition

if camera input is =0 all three signals =0 value camperainput is on is to go to output

 

here we using the block mux its shows output here 

and add signal input block is used inbetween mux and output because  

signal conversion : here it is ussed to all signals output is copy and same output shows in output

 

shown in below figure

when signal conversion is not their in between them we get an error while run the circuit as shown in below

see the below the use of signal converter:

 

 

With out signal converter when we run the simulation of the circuit its shows an error

shown in below without a signal converter:

After run the simulation we dont get any errors  this is the first condition after go to modelling tab and go to model advisor select

After open a new dialogue box shown in figure

 

 

in this model advisor has two categories my project and my task

 

here we use products it can be so multiple options like codes  these is using for code generating which option you want select that one

here we useans select the by task we are checking of all types of iso 's here mab guidelines under task

See the below figure::

here see the below dialogue box see the we have underline 

in this we select the modeling standard of MAB  see the right side we have pass fail, warnings, not run conditions in this condition we dont have any failed conditions 

and modifi erros and warning as well as rectifing warnings and finally it will be maximum all well correct errors here finally go to run select checks it can be shown the rectifieng warning after you check the files and run this condition

 

totally they are 144 checks done on the model

it is on model settings are block settings it is any in correct its shows warning condition or error message and failed condition

here go to model advisior checks

here we can rectify  and eliminate maximum no of warnings

here select the modeling standards of MAB block tick and run selected clicks

here to click continue it takes some time because there are 144 checks can be checked

 

 

here checking our complete module according to guidelines

here checking the condition there is an errors in block conversation block names etc

 

 

and folders also specific characters numbers its also shown error under naming conventions

 

HOW TO CHECK ERRORS :

here below shown figuare there is underline  see the left side there is a block showing error symbol it is in yellow colour in that we open that ewe have see the right window there is showin errors in blue colour underlined  see the we underline we see the read carefully and go to blue colour warning and click there it can be take direct to design your circuit block and shown an yellow colour and rectify the option after that you will select the runthis check it is be disappear in that block lists

here see the model settings its go to direct setting parameter block also

 

 

Finally maximum no of reducing errors

 

Finally after run this checks we go to generate the report 

 

 

here generate the report were is the folder in current directory save in path way

here we generatee report in HTML in saving MAAB_REPORT

the report is shown in below figure

 

write the test cases in below 

take a excel give the input to you design a circuit give the test condistion and make a excel report and save it Test_signals.slxs

 

here we use any signal but i preffered step wave is input to test case

 we gives value  in step wave form

1st case : 0-1sec time positive value=30  , camera input on its turn on right

2nd case: here we give  time 1-2 sec, negative value is=-120 in this camera input =1 its turn on and its turn to left 

in 3rd case:  we given time 2-3 sec,value=0 its turn on camera=1 its go to straight

4th case: we give time 3-4 sec, positive 50 camera input sign is =0,its turn off the signal mode

 

TEST HARNESS::

here dont change in main block system

here create a test harness go to main block and right click to the sub system see the below figure to understand easily

 

there is another block is open  input source using signal builder in this option

 

 

 

 

 

in this block we go to advance settings in this

 

in this the advantage setting to verification mode is in normal it is used a mill test harness is created

In this there is open a new window be like this shown in below Figure

here we use the signal builder go to signal builder and double click  and import  input test cases excel sheet to signal builder

 

After import test cases of excel file in to a Signal builder here select all cases  shown in below figure import all test cases we have done

 

 

see the below after importing test keys in excel  the signal input of a signal builder has two inputs three outputs 

here streeing wheel angle is 0 to 1  second the graph shows 30 camera is on 1-0-0 ( Right turn)

2. here 1-2 second the graph shows steering value is negative  ,camera input is on  it goes to left turn (0-1-0)

3. here 2-3 seconds the graph shows steering value is zero(0) ,camera input is on (1) it goes straight (0-0-1)

4. here 3-4 seconds the graph shows steering value is 50 camera input 0 it becames(0-0-0)

these are 4 test keys in the excel

 

here the circuit we are using Mux block because we see the actual output and excepted outputs we are given the mux in to three connections because

1. left turn 

2.right turn

and 3.straight  

see the below figure given the three numper of outputs

here see the below circuit to use sum for using actual  and add scope using three sum blocks 

here 1 sum block is used to left turn and another

second sum block is used to right turn and

third sum block is used to straigh connections in these finally connected to scope for output

 

here we use the sum because ecxcepted output- actuall output

in above there is a another scope is used because to see the actuall output

 

SCopE input and output

NOTE: here  shownn below Excepted output ,actual output As shown similar in scope

 

 

FINAL CIRCUIT OF MILL TEST HARNESS ;:

shown in below circuit

After mill test harness go to main circuit block 

seen in below circuit after finish of mill test harness it will be save as like  this

CELL TEST HARNESS:;

first we go to change subsystem in to Automatic subsystem

After that subsystem right click and Go to block parameter sub system shown in below

 

next there is aanother dialogue box is open and select option next go to Apply and ok here  change the sample time 0.01 or -1

 

 

After go to subsystem  again  right click go to test harness and select create vehicle direction

 

here same as previously doing same process again here the bassic property we use inport as a signal builder and go to

 

 

go to advance property here see the highlighted circle here verification mode: normal mode changes in  software in  the loop (SIL)

 

 

 

 

next see the programming file in a new window

 

After containing generating  c-code the file is generating like this inn your current path folder is saved

 

 

After software loop system it is masked the subsystem shown in below figure represents

 

 

 

In this go to subsystem under mask see the below circuit you can understand easily there is a red mark under line it is already done software in loop generating c code 

 

 

same as previously we import file  test keys of excel sheet in to a signal builder  select all signals  see below

 

 

After that see the below diagram we have mux block and sum block and 2 scopes look like this same 

here also this is same condtion excepted value and outpul value is similar are not shown in scopes see the below circuit

 

same output given exceptep value is similarly as output values by see in scope 1 and scope 2 b shown in below

here the circuit run in 4 seconds finally output in software Test in loop

 

 

 

Go to our main block system here we see as do right 1. Mill harness system and 2. software test in the loop seen in a main block of subsystem

 

 

 

EMBEDDED C CODER:

 

here we cannot do any tests here its a direct option to convert in to a code see below direction option we can see in the below figure

 

after than we see in a ribbon bar c-code option then click to confirm to build

 

previously we build a c-code and now only we will show the direct process there is no changes in code generation similarly  in the same way   files are also save  name  in same  current folder path see the below figuare

 

 

 

 

Afterr building and generating c-code we have a view option is there see the code configurations after select the view option

 

 

TAGGING REQUIREMENTS:

here we  copy the question in to a MS-word file and save in amini project file in that we use a requirement tagging in a subsystem block 

here open Ms Word file open scroll down to Requirement 1 Select and minimize ms word file go to main block system go to  requirement 1 give to right click go to requirements  and select link to selection word see the below figure

 

 

1. select requirement be like this

 

 

 

 

 

 

After that give right click and select  and tagging like this after tagging requirements we will confirmation we can see the tagging or not see this and check the which one we tagging

 

 

And see the requirement 2  also tagging another subsystem requirement 2 also like this  we see the above figure there is showing requirement is taging  we open and click there its direct to go ms word file see that option were we requirement tagging
