Project 1 (Mini Project on Vehicle Direction Detection

Mini Project - Vehicle Direction Determination

Requirement Analysis[Create the word document file of given Req.]

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).

Simulink Model

Create simulink model

SLDD

Now create and link SLDD for model

SIGNAL RESOLVE

NAMING AND ANNOTATION

Give proper names and annotation to blocks , also assign correct data types

Solver Setting

By clicking on model conf. option do the solver setting as per req.

Here sover type is fixed with start time 0 sec and stop time is 10 sec along with step size is 0.01

RUN MODEL

After this just run simulink model and just check error and warning , if there is no error and warning then do Model Advisory check

Requirement Tagging And Tracibility

1st create a word file of given req.

Then select req. of specific sub system by clicking on option Requirement then Link selection in word allot to it.

To trace req. just inside of Apps then Requirements Manager

Model Advisory Check

1. System integration without problems.
2. Well-defined interfaces.
3. Uniform appearance of models, code and documentation.
4. Reusable models.
5. Readable models.
6. Problem-free exchange of models
