Project 1- Traffic Jam Assistant Feature

Aim:

To develop a model for Traffic Jam Assistant algorithm as per given requirement and perform Code generation, Model Advisor Check.

Model:

Explanation:

To create a data dictionary for the given input/output signal and calibration signals.

  Modelling Tab -> Link to  Data Dictionary and choose ADD option to add the signal and modify the parameters.

Requirement 1:

The input signal(input_voltage) is compared against the Maximum voltage range and minimum voltage range. The output signal of the relation operator is given to the AND Block ( optimum_voltage)  and it is taken input to the next subsystem.

Requirement 2:

The Enable_Display signal is given as input to the control port of Multiport Switch. Depending upon the enable signal On mode /OFF mode / STANDBY Mode is chosen and fed to 1st input of the switch block. The 3rd input of the switch block is No display.

The NOT value of input signal “Input_Switch” is compared in an AND gate against 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. Depending upon the value the first input or third input is chosen and given as output of the subsystem.

Code Generation:

In Configuration parameters, chose solver as fixed-step and in Code Generation Tab, System Target file is ert.tlc

Model Advisor Check:

In Modelling TAb, Click on Model Advisor and select the system and click on Modelling Standard on MAB  in BY task and click on Run.

Result:

Thus model for Traffic Jam Assistant algorithm as per the given requirement is developed and  Code generation, Model Advisor Check is performed
