Project 2 - Development of TFT Cluster Speedometer Software Component

Development of TFT Cluster Speedometer Software Component

Aim:

To create a simulink Model for the TFT Cluster Speedometer .

Requirements:

1.1 Calculating TFT Display Speed

Average Vehicle Speed would be displayed only if its between 2 kmph & 250 kmph. Any value outside this range will be discarded by its lower limit & upper limit

When Average Vehicle Speed is < 2 kmph, DisplaySpeed = 2 kmph

When Average Vehicle Speed is in between 2 kmph & 250 kmph, DisplaySpeed = Average Vehicle Speed

When Average Vehicle Speed is > 250 kmph, DisplaySpeed = 250 kmph

1.2 Main Data Filtering

Main Data Filtering subsystem will be activated for every 10th millisecond

DisplaySpeed1 (t) = ((DisplaySpeed (t) x 0.65)/ Main Filter Speed Value) 0.05

1.3 Auxiliary Data Filtering

Auxiliary Data Filtering subsystem will be activated for every 10th millisecond

DisplaySpeed_Filter (t) = ((DisplaySpeed1 (t) x 0.78)/ Auxillary Filter Speed Value) - 0.03

1.4 TFT Speed Output

If |(DisplaySpeedFilter - DisplaySpeed)| > 1.5

{

Vehicle Speed Display = DisplaySpeed

}

else

{

Vehicle Speed Display = DisplaySpeed Filter

}

8.SLDV test generation report

9.Poly space analysis report / outputs

Steps to create a Polyspace Report:

• Initially, open the Polyspace in that new project click on start new project.
• The Project Properties dialogue box will open in that give the project name as we saved in the MATLAB,then select the location where it we need to save after that click Next or use the default location.
• Then ,it asks for the Projrct source,click on browserand select the folder where th .c file are generated then optionally we can add the include folder then clock on finish,the polyspace environment will open.
• In the configuraton settings option called Target & compiler select the source code language as c,change the target processor as X86_64.
• In the coding standards & code Metrics in that enable the check MISRA C:2004 also select the calculate the code metrics option
• After that go to bug finder analysis under that select the default one.
• Go to reporting enable the generate report option and ouput formet as PDF or any file we need
• Finally save the polyspace and run the Bug Finder.

10.Test manager reports – baseline & back-to-back testing

Baseline

Back to Back

Result:

The expected outputs are obtained for the Simulink Model TFT Cluster Speedometer.
