Project 2 Adaptive Cruise Control
Aim: To develop an MBD-compliant Adaptive Cruise Control feature as per the provided requirement document using MATLAB Simulink
Objective of Main Project:
- Developing Adaptive Cruise Control feature as per the Requirement Document using MATLAB Simulink.
- Follow all the MBD related processes: Requirement Tagging & Traceability, SLDD creation, Configuration Parameter changes, Model Advisor check & Code Generation.
- In Configuration Parameters: enable “Support Floating Numbers” under Code Generation settings.
- Use Embedded Coder to generate the code.
- If choosing code generation, Storage class for Input signals: ImportedExtern; Storage class for Output signal: Export to File; Storage class for local signals: localizable; Storage class for calibration signals: Const.
- Choose sample time for all signals as 0.01s
Model:
The base model consists of 9 inputs and 4 outputs as given in the requirement:

Inside the Adaptive Cruise Control Subsystem, We have created 3 subsystems for the 3 main requirements.
Requirement 1: Lead Vehicle is designed inside the Lead Vehicle Subsystem
The radar & camera inputs are added to get the Lead Vehicle Speed Output.
Requirement 2: Drive Vehicle is designed inside the Drive Vehicle Subsystem
The radar & camera inputs & Acceleration mode are added to get the Drive Vehicle Speed Output.
And the radar input is passed through a Signal Conversion block to get LeadVehicle_Detected.
Requirement 3: Adaptive Cruise Control Algorithm is deigned with state machine logic. The inputs of this are the rest of the unused inputs and the outputs of the req 1 & 2, And the output of it is the Acceleration Mode.
Inside the Sate Machine Chart, the main states are ACC_ON, ACC_OFF and ACC_STANDBY. These are deigned by the logic given in the requirement description itself.
