Project 1 (Mini Project on Vehicle Direction Detection

Ans.)

Aim:-

To create the Vehicle Direction Determination model according to the given requirements.

Objective:-

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 the this project. scope of

4. If choosing code generation, Storage class for Input signals: Imported Extern; 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 :-

Subsystem of main model :-

Requirement 1 Subsystem is shown below :-

• Steering wheel input as yaw rate (Signal name: Steering Wheel_YawDegreelnput) is the input for this system.
• This is compared against 3 angular values, one each for a 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 & the output of this requirement is a local signal (Signal Name: Vehicle_Turn_Status).

Requirement 2 Subsystem is shown below :-

• Keep this requirement as a separate subsystem. Inputs to this requirement are a local signal from requirement 1 (Signal Name: Vehicle_Turn_Status) & an input signal from the camera (Signal Name: Cameralnput_RoadSign), which confirms the occurrence of a road sign.
• Signal Vehicle_Turn_Status is compared against calibration values (Calibration Values: Right Turn_RoadSign, Left Turn_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).

Procedures :-

• Tagging of the requirement with the model :-

The reqiurement is written in MS Word which is then tag with each sub system as shown below

• Linking the model with SLDD

• Changing configuration parameter

For simulation solver setting Change sample time as given below:

Results:-

The signs are in the way that Right, Left and Straight respectively.

As the output is boolean, If we get the output as (0,0,1). Then the vehicle is moving in the straight drive.

If the output as (1,0,0), Then the vehicle is taking in the Right turn.

If the output is (0,1,0), Then the vehicle is taking the Left turn.

After running the simulation, we can clearly see that the vehicle is moving the straight direction.
