Project 2 - Development of TFT Cluster Speedometer Software Component

1.Development of TFT Cluster Speedometer Software Component

Cluster Instrument receives the signals from other ECU via CAN bus interface. It also receives commands from the driver via steering wheel buttons. The signals are then processed by the Cluster ECU, after which the Cluster ECU may send the vehicle information to the LCD or light the LEDs and so forth, according to the results. Therefore, the Cluster ECU can be viewed as a carrier of the information flow.

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, Display Speed = Average Vehicle Speed

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

Requirements:

Calculating TFT Display Speed:

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

}

Solution:

Aim:

To create or design the wiper control system is designed by using state flow and Simulink blocks.

Design:

Circuit is designed in MATLAB R2018a and R2020a version.

1) Circuit had designed as per the given conditions.

Simulink Model:

2) Creating SLDD as per the given challenge.

SLDD:

3) Creating Requirement Tagging.

Requirement Tagging:

4) Checking JMAAB compliance report from Model Advisor.

Model Advisor - JMAAB compliance:

Reports had attached

5) Checking Fixed Point Tools for the given model.

Fixed Point Tools:

6) Checking SLDV Designe Error and test generation implementation and generating reports.

SLDV Designe Error and Test Generation:

7) Generating Functional test cases, MIL, SIL Harness and Coverage reports.

Functional test cases, MIL, SIL Harness, Signal Builder and Coverage reports:

8) Outputs for the Functional test cases, MIL, SIL Harness.

Outputs for the Functional test cases, MIL, SIL Harness:

All the outputs had attached

9) Polyspace analysis report/Outputs.

Steps to create the Polyspace Analysis 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 generation,

a) Base_Line Test and b) Back to Back Testings.

Test Manager Report Generation:

All the test reports had attached along with required screen shots

11) Results has obtained as per the designed Model for the given challenges.

Results as per the designed model:

All the test reports had attached along with required screen shots

Note:

All the models had designed and attached along with screen shots.

As per the discussion in live session this project is submitting.
