Project 1 (Mini Project on Vehicle Direction Detection

1) Development of MATLAB Simulink model as per requirement.

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).

Model:- For the vehicle direction detection , we have 2 input (SteeringWheel_YawDegree and CameraInput_RoadSign)and the output(Vehicle Direction Indicator). These system consist of different logic are as follows:-

As per requirement we create two subsystem which is requirement 1 and requirement2 tagging with word file.

In case of requirement 1 there is three condition, the input (SteeringWheel_YawDegreeInput) compare with 3 angular values as shoen in fig.which is (Right_Turn_AngularLimit, Left_Turn_AngularLimit, Straight_Drive_Steering_Angle) to say which specific direction the steering wheel is turning toward.

As per requirement 2 the vehicle turn status will act as input to direction indicator logic subsystem where,calibration value are compared (RightTurn_RoadSign, LeftTurn_RoadSign, Straight_RoadSign)If each of them found equal then each of three corresponding output is compared against camera input.

These is signal compared with the value given as per condition. RightTurn_RoadSigncompared with 30, LeftTurn_RoadSign compared with -120, Straight_RoadSign compared with 0.

SLDD FILE :-

All signal are stored in sldd.and model is ready for run.

We also done the coverage analysis.report are attach .
