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

Requirement - 1:

• 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).

• The Above Diagram Show the requirement 1 subsystem
• steeringWheel_YawDegree is the Input
• Vehicle_Turn_Status is the output of the subsystem

Requirement – 2:

• 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).

• The output of the requirement 1 subsystem is the input for requirement 2 subsystem
• And another input is CameraInput_RoadSign
• Vehicle_Direction_Indicator is the output of the requirement subsystem

Model

• In this model we connect the two subsystems requirment 1 and requirment 2
• after that we want to asign a value for all the inputs by data distnory
• Go to the modulibg tap and click the model exploer
• 
• After that a new window will open
• we Want to assign a value in that the values are given below

After Entering Inpu its look likes

Result

A Simulink Model was created and the input values are assigned as the Requirements
