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

Question - 1 - Wiper control system

Develop Simulink/state flow model for wiper control system based on the given conditions.

Description of Challenge:

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

Note: Rain density input comes from the external sensor, for the simulation purpose constant block with knob can be taken.

SOLUTION

FINAL SIMULINK MODEL

Condition-1. If the density of the rain is low, then wiper rotates with low speed, the output signal should be 100 rpm

Here we taken,

• No_Rain >= 0
• Low_Rain >= 1
• Medium_Rain >= 2
• High_Rain >= 3

Condition-2. If the density of the rain is medium, then wiper rotates with low speed, the output signal should be 200 rpm

Condition-3. If the density of the rain is high, then wiper rotates with low speed, the output signal should be 500 rpm

REQUIREMENT TAGGING & REPORT

FIXED POINT TOOL

We will Apply Proposed Data Types Proposed by Fixed Point Tool

DATA TYPES ARE APPLIED AS BELOW

AFTER SIMULATE WITH EMBEDDED TYPES AS BELOW

SLDV Design error detection report

SLDV Test Generation Report

ADVISOR Shows all things are Analyzable

Generated Test Case

There are 2 test cases generated. and we can see it in PDF report.

MANUALLY WRITTEN FUNCTIONAL TEST CASE

MIL TEST HARNESS OUTPUT

SIL TEST HARNESS OUTPUT

AUTO CODE GENERATION REPORT

POLYSPACE STATIC ANALYSIS REPORT

We have to Purchase the PolySpace Licence Seperately to Get the full Execution.

Steps :

• Open Polyspace Software
• Start new Project and give name and set storage location
• Project Include Folders >> Select the folder where project(.c) files are saved...

Then, Ensure the Parameter Settings

• Target & Compiler >> Target Processor Type >> x86_64
• Coding Standards and Code Metrices >> Check MISRA C : 2004
• Bug Finder Analysis >> Default
• Reporting >> Generate Report

Then, SAVE & RUN......
