Project 1 (Mini Project on Vehicle Direction Detection

Mini Project on Vehicle Direction Detection

Aim- Create a simulink model which will detect the direction taken by the vehicle based on the camera and

steering rotation angle.

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

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).

Procedure-

1. Steering angle as input

1. I have taken steering angle as input and based on limit value I have given condition as 30 degree and 120 degree

and after camparision it will give output as left_turn sign and right_turn sign as per the condition.

2. I have created it under one subsystem and output of this system I have done logical operation based on input It will

give output high for the particular direction as left turn, Right turn and straight as shown in the screenshot below.

3. I have taken camera input and fed to logical operator output of this I have to fed to AND gate for verifiction of signal

so that accuracy should increase.

4 Output of this I have connected to multiplexer used as output port.

5. I have given all the variable name and also saved in SLDD file as per the given data.

6. Configration setting as fixed step 0.01 descreate continuous.

7. I have propagated all the signal.

8. I have uploaded all the signal in the signal builder.

9. I have done MIL testing.

10. I have done advisory check that I have uploaded below.

11. SIL testing also I have done and code I have uploaded below.

Output-

I have done MIL and SIL testing of the above model I have get all the model working fine and expected output matching all the model output.

MIL Test Output-
