Project 1 (Mini Project on Vehicle Direction Detection)

Aim:- To Create a Simulink Model Vechile Direction Status as per Requirement Data.

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).

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).

Objective of Mini Project:

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:-

Procedure :-

• Firstly i create Requirement 1 in this requirement 1 inport ,1outport , 3 constant Block ,2 switches is used and connect them . if the input is >=30 (intial Values = 30) the vechile will take right Turn , else if the input is not equal to zero (~=0) the vechile left turn , else straight drive ( if the input equal to zero).

• Then i create Requirement 2 in this requirement 2 inport , 1 outport , 3 Compare to constant Block ,3 Logical operators (OR) , 1 MUX Block is used and connect them as per requirement. vechile turn status is compare with Right turn, Left Turn & staright road design and this is signal is going tto OR block and in OR block this signals are compare with Camera Input Road Design.

• and both requirement attach them and create subsystem (Vechile Direction Status ). and then crate SLDD file and open SLDD File create signals and param as shown the SLDD File in image. and Run the Program.

Results:-

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

2) As the output is boolean , if we get the output as (0,0,1), Then the vechile is moving in the staraight drive.

3) if the output as ( 1,0,0), Then the vechile is taking in the Right Turn.

4) if the output as ( 1,0,1), Then the vechile is taking in the Left Turn.

Conclusion:-

Create a simulink Model for Vechile Direction Status and create SLDD File for vechile Direction Status.
