Project 1 - Wiper control system and Vehicle speed calculation for ABS using Wheel Speed sensor

EElakkia Elumalai6 Feb 2023

Aim:To Develop the Simulink model for wiper control system based on the given conditions and also create SLDD file and link the same to the model. Perform the complete V and V workflow for the obtained models.

Conditions:

If the density of the rain is low, then wiper rotates with low speed & the output signal should be 100rpm
If the density of the rain is medium, then wiper rotates with medium speed & the output signal should be 200rpm
If the density of the rain is high, then wiper rotates with high speed & the output signal should be 500rpm

Aim:

To develop a Simulink/state flow modules for wiper control system based on the given conditions.

Conditions:

If the density of the rain is low, then wiper rotates with low speed, the output signal should be 100rpm
If the density of the rain is medium, then wiper rotates with low speed, the output signal should be 200rpm
If the density of the rain is high, then wiper rotates with low speed, the output signal should be 500rpm

8.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

9.Test Manager report- baseline and back to back testing

Back to back testing

Aim:To Develop the Simulink model the vehicle speed calculation unit inside the ABS system based on the given conditions and also create SLDD file and link the same to the model. Perform the complete V and V workflow for the obtained models.
