Project 1- Traffic Jam Assistant Feature

Traffic Jam Assistant Feature

Working procedure

This model must be developed in MATLAB Simulink as per MBD guidelines according to the requirements given.

Tag the requirements to the Simulink model, Requirements 1 & Requirement 2 are tagged into their corresponding subsystems.

Creation of Simulink Data Dictionary for the model & must be linked to the model.

Tagging for Requirement 1 and Requirement2 subsystem.

Creation of Model Advisor Report for given Traffic Jam Assistant Feature model. Code Generation Profile must be in Embedded Coder

Traffic Jam Assist feature brakes and accelerates the car for the driver, while maintaining a safe distance from the vehicle in front.

The driver has to permanently supervise the system & be ready to take over the complete control of the vehicle at any time

Main Model

this is the main model, with three inport and one outport

And resolve the signals like this

same thing you have to do for output also

resole the signal with name which was given in the requirement

Now double click on the subsystem, and seems like this

As per requirement given in the question, need to create a subsystem in and the output of the subsystem is connected with the requirement 2

Inside the subsystem we need to propagate the signal which we have initialy resolved in main model

like this we have to propagate the signals for other input also

Condition for Requirement 1

Requirement No 1:

• Input Signal “Input_Voltage” is compared against voltage values “VOLTAGE_MINIMUM_RANGE” & “VOLTAGE_MAXIMUM_RANGE”.
• Incoming input signal “Input_Voltage” must be greater than – equal to “VOLTAGE_MINIMUM_RANGE” and less than – equal to “VOLTAGE_MAXIMUM_RANGE”.
• Output signal from here is “Optimum_Voltage” which will be one of the inputs to the subsystem “DisplayUnit”.

Now name the subsystem as requirement 1

and double on the subsystem

Input Signal <Input_Voltage> is compared against voltage values VOLTAGE_MINIMUM_RANGE & VOLTAGE_MAXIMUM_RANGE.

Incoming input signal <Input_Voltage> must be greater than – equal to VOLTAGE_MINIMUM_RANGE and less than – equal to
VOLTAGE_MAXIMUM_RANGE.

Output signal from here is <Optimum_Voltage> which will be one of the inputs to the subsystem DisplayUnit.

However, output signal (i.e Optimum_Voltage) is form newly in this subsystem hence we resolve this signal by right clicking on signal
properties

and need to resolve the signal for Optimum-voltage on output

Now propagate the signal on output and need to connect it with requirement 2

Requirement No 2 (DisplayUnit Subsystem):

• Input Signals are “Optimum_Voltage”, “Input_Switch”,“Enable_Display”. Signal “Enable_Display” must be saturated between the range 0 – 7. Output signal from the subsystem is “Output_Display”.
• Input Signal “Enable_Display” is compared against pre – defined set of values in a multiport switch. Total data ports in the multiport switch is 5.
• Multiport switch inputs 1 & 2 is connected to calibration signal “ON_MODE”, Multiport switch inputs 3 & 4 is connected to calibration signal “OFF_MODE” while Multiport switch input 5 is connected to calibration signal “STANDBY_MODE”.
• The output from Multiport switch is connected to the first input port of the Switch block. The third input port of the Switch block is connected to the calibration signal “NO_DISPLAY”.
• Meanwhile NOT value of input signal “Input_Switch” is compared in an AND gate against input signal “Optimum_Voltage” and the output from comparing if calibration signals “INTERRUPT_1” & “INTERRUPT_2” are equal. The output of the AND gate is the second input of the switch block.
• The output from the switch block is “Output_Display”.

Now double click on the subsystem 2 which was named as requirement 2, And inside the requirement 2 it seems like this

As per given requirement

saturation block been with inport and output has been connceted with multiport switch 1

and set the lower range as 0 and upper range as 7

create a multiport switch and set a number of switch port as 5

Now create a three constant block

and name it as ON_MODE, OFF_MODE, STANDBY_MODE

now connect ON_MODE block in switch 1 & 2

then connect OFF_MODE block in switch in 3 & 4

and finally connect STANDY_MODE block in switch 5

as per the condition given in the question

Now for Inport 2 & 3

it has been connect with and block

Inport 2 directly connect to And block and Inport 3 connect with not block and then it connect with and block

And finally INTERRUPT 1 & 2 is connected with relational operator with double equal and then it connected with And block

Now the Multiport output and and block output connect with switch block

and it will give excepted output while run the program

Thus the Requiremt & 2 been fully explained

Now need to chech MAB guidline for this model

Before that need to add Data dictonary for the model

For that Signals and parameters has been given in the model

Input Signals:

Name of the Signal	Data Type	Range
Input_Voltage	uint8	0 - 255
Input_Switch	boolean	0 – 1
Enable_Display	uint8	0 - 255

Output Signal:

Name of the Signal	Data Type	Range
Output_Display	uint8	0 - 255

Calibration Signals:

Name of the Signal	Data Type	Range	Initial Value
VOLTAGE_MINIMUM_RANGE	uint8	0 – 255	30
VOLTAGE_MAXIMUM_RANGE	uint8	0 – 255	50
OFF_MODE	uint8	0 – 255	2
ON_MODE	uint8	0 – 255	1
STANDBY_MODE	uint8	0 – 255	3
INTERRUPT_1	boolean	0 – 1	1
INTERRUPT_2	boolean	0 - 1	1
NO_DISPLAY	uint8	0 – 255	0

Local Signal:

Name of the Signal	Data Type	Range
Optimum_Voltage	boolean	0 - 1

In SLDD Local signals, Input signals, output signals been taken in signal block

And calibration been taken in Parameter block

To create a SLDD file first we need to create a new SLDD file

Now click the modeling tab on the tab, And select model setting

Set sample time as 0.01

And in solver selection as Fixed type and discrete( no continous states)

And click on code generation

and click on browse and select Embeder code and click on ok.

Now need to create as SLDD

now click on modeling tab and select link to data dictonary

in that new pop up window click on new and create SLDD with the file name

Now the SLDD been creatted and save it.

Now need to check model advisor check for MAB gudline as per the conditions

so Click on modeling tab and select model advisor

now click on ok, then new tab will be open

in that need to select Model standard for MAB and run and the result for MAB has been on the above screen

Now MAB guideline has been checked and it been run sucessfully

Now need to generate the C code for this model

For that need to select APPS on the top and select EMBEDED coder

on the top new tab will be open like C code

in that need to click on generate code then the c code will be generated

and it will attached below
