Project 1- Traffic Jam Assistant Feature

Jam Assistant Feature

AIM :

• Model Development of a single feature of Traffic Jam Assist using MATLAB & Simulink as well as Code Generation using Embedded Coder .

Objectives :

• Model Development as per MBD guidelines . Creation of Simulink Data Dictionary .
• Code Generation using Embedded Coder Generating Model Advisor Report .

• Data Dictionary creation :

  (TrafficJamAssistant.sled )

  • A new Simulink data dictionary is created and updated signals & calibration Data List as per our requirements .
  • The very first thing that we will do is create a Simulink Data Dictionary using the given Signal and Calibration Data List.
  • 

  • Solver configuration parameter :

    • Solver type : Fixed
    • Solver : discrete ( no continuous states ) Sample time : 0.01
    • Code generation Parameters : System target file : ert.tlc ( Embedded Coder ).
    • 

Designing MATLAB Simulink Model :

• The Input Voltage , input Switch , and the Enable switch are the inputs to the system , and the Output Display is the final Output from the system .

Requirement 1 :

• Input Signal " Input_Voltage " is compared against voltage values " VOLTAGE_MINIMUM_RANGE " & " VOLTAGE_MAXIMUM_RANGE " . Then their outputs are given as the input for AND block , the Output of which is Optimum_Voltage .

Requirement2 :

• Optimum_Voltage from the Reql , " Input_Switch " , and " Enable_Display " are the Input Signals . The output signal from the subsystem is " Output_Display " .
• Signal " Enable_Display " must be saturated between the range 0 - 7 .
• Input Signal " Enable_Display ' is compared against a pre - defined set of values in a multiport switch . The total data ports in the multiport switch are 5 . Multiport switch inputs 1 & 2 are connected to calibration signal " ON_MODE " , Multiport switch inputs 3 & 4 are connected to calibration signal " OFF_MODE " while Multiport switch input 5 is connected to calibration signal " STANDBY_MODE " . The output from the 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 the value of the input signal " Input_Switch " is compared in an AND gate against the 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 " .

Requirement Tagging :

• Requirements can be a tag to requirement 1 & requirement 2 to their corresponding subsystems with word files.

Model Advisor Check :

• Model Advisor Check on Modelling Standards for MAAB .
• Model Advisor Check completed with 8 warning and 110 check passed.
• There are warinings that are acceptable but the notable part is that there is not a single failed result.

Model Advisor Report :

• Model Advisor Report can be generated,we can choose the format HTML,PDF or Word Format.
• HTML Report is generated and saved in the directory.

Code generation :

• By using the embedded coder app we can generate code and build our model.
• Successfully conducted model build and generated code . The generated codes and files can be seen in the current directory .

Conclusion :

Developed a model of single feature of Traffice Jam Assist as per MAAB Guidelines as well as created Simulink Data Dictionary using MATLAB & Simulink.Generated a code using Embedde Coder and generated a Model Advisor Report.
