Project 2 Adaptive Cruise Control

Aim:- To develop the Adaptive Cruise Control feature as per the Requirement Document using MATLAB Simulink.

Explanation:-

• By refering the requirement 1 we build a model by using the suitable blocks.
• By reffering the second requirement we crate the model.
• by fulfilling the requiremennt 1&2 we created a subsystem .
• after requirement 1& 2 we move on to make the chart and we maked a chart by using the given requirement.
• in the reuirement 3 we have six subparts from where we use to give the various output signals.
• after the whole requirement we make a subsystem in which the reuirement is been fitted.

Result:- We get the model advisor report with 23 warnings items and 120 passed item for performing MAB test.

With the help of app file we generated the code also.

Conclusion:- The Adaptive cruise control is designed according to the requirements. The code is generated by using embedded coder. The model is checked for MAB test using Model Advisor and report is added. The requirement blocks are linked to selection in the Word document. There are many advancements in the Adaptive cruise control like turn by turn ACC, the vehicle automatically changes the speed according to the road condition, traffic, turning and slope.
