Project 1 (Mini Project on Vehicle Direction Detection

Mini Project - Vehicle Direction Determination

Aim:-

1. Development of MATLAB Simulink model as per requirement.
2. Tag the requirements to the simulink model; tagging requirement 1 & requirement 2 to their corresponding subsystems is fine.
3. MBD compliant changes, Data Dictionary creation & code generation is added advantage, and that is not scope of this project.
4. 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.
5. Choose sample time for all signals as 0.01s

Simulink Model:-

Simulink model is built with given requirement.

 

SubSystem:-

Description:-

• One input that is connected to the system that is "SteeringWheel_YawDegreeInput " signal according to the input we have to decide which side the vehicle turn like Left _turn , Riht_Turn ,Straight_Drive .
• Compare SteeringWheel_YawDegreeInput with the Left _turn , Riht_Turn ,Straight_Drive tO get our desired output the signal name "Vehicle _Turn _Status".
• Here we have to compare with switch block to get corresponding output.
• TheVehicle_Turn_Status output signal is input as requirment -2.
• Based on vehicle_turn_Status and camera_Input with these 2 inputs ,the it will decide to which side turn required.
• The camera_Input is connected to the system ,according to the carema view ,we have to decided which side turn with this vehicle is turn .
• The three camera signs ,based on these we have to compare final output is get the signal name is Vehicle_Direction_Indicator.

Requirement1:-

• Steering wheel input as yaw rate (Signal name: SteeringWheel_YawDegreeInput) is the input for this system.
• This is compared against 3 angular values, one each for left turn, right turn & straight drive (Calibration Values: Right_Turn_AngularLimit, Left_Turn_AngularLimit, Straight_Drive_Steering_Angle) to say which specific direction the steering wheel is turning towards.
• Use switch blocks to compare & develop this requirement. Keep this requirement in a subsystem & output of this requirement is a local signal (Signal Name: Vehicle_Turn_Status).

Requirement2:-

• Keep this requirement as a separate subsystem. Inputs to this requirement are local signal from requirement 1 (Signal Name: Vehicle_Turn_Status) & an input signal from camera (Signal Name: CameraInput_RoadSign), which confirms the occurrence of a road sign.
• Signal Vehicle_Turn_Status is compared against calibration values (Calibration Values: RightTurn_RoadSign, LeftTurn_RoadSign, Straight_RoadSign), if each of them is found equal, then each of the three corresponding output is compared against the camera input signal.
• Using a logical operator block, only one among them is finally given as output signal (Signal Name: Vehicle_Direction_Indicator).

SLDD File:-

SLDD file is created with the given signal parameters and loaded into workspace.

Reports:-

To generate reports, model is checked in Model Advisor window.

In this tab, required tasks are checked for warnings and errors and can modify to remove them.

After that, the report can be downloaded for future purposes.

Reports give the details of errors and warnings.

C code Generation:-

C code is generated for the model and required documents are downloaded like .c,.h files.

Conclusion:-

Therefore, required model is built with the given requirements, Data dictionary is created and loaded and model is simulated and reports are generated.

All the required files are attached.
