Project 1 (Mini Project on Vehicle Direction Detection

Mini Project on Vehicle Direction Detection :

General Overview:

Identifying the direction of the vehicle is one of the important & diverse features in Autonomous driving & Advanced Driver Assistance Features. This particular sub-feature of identifying the direction of vehicle is basically identifying the direction the vehicle is taking based on the camera input.

Camera reads the road signs & stores into its memory with unique values for left turn, right turn & straight drive. Depending on the direction it is taking, final indication is given to the driver – as an indication if he is driving in the recommended direction or not.

Vehicle Direction Determination can also be coupled along - side features like GPS systems to identify whether the vehicle is reaching its destination in an optimized manner. This sub feature can also be used along with Lane Detection, Highway Warning, Ramp Entry / Exit in Wrong Way Detection etc.

By making subsystem blocks I completed Vehicle Direction Detection system.

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).

Procedure :

First of all I created a subsystem ,which Has two inputs signals SteeringWheel_YawDegreeInput and CameraInput_RoadSign ,By some machanism into subsustem I got Output signal Vehicles_Direction_Indicators which is calibration value. in the subsystem blocks one signal SteeringWheel_YawDegreeInput

this input signal divided into three signals 1.Right_Turn_AngularLimit,2. Left_Turn_AngularLimit,and 3. Straight_Drive_Steering_Angle ,all 3 signals connected with three relational operaters and also three switches ,if in chase1 Right_Turn_AngularLimit is true then it will be executed for output ,else i chack second signal one .

chase 2 if Left_Turn_AngularLimit signal is true then executed else,chack for last one ,if Straight_Drive_Steering_Angle is true then vehicle ture on else ,0 will be default value .

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).

In here two input blocks Vehicle_Turn_Status and CameraInput_RoadSign which is connected with three signal RightTurn_RoadSign, LeftTurn_RoadSign, Straight_RoadSign these three are connecte with oppractional AND opperater which has two input ports one is connected with three signal other connected with CameraInput_RoadSign signal .each AND operater blocks are connected with musk ,all 3 signals connected with signal conversion. this camera input catchup road condition by given the responce by camera the vehical turn on and moved left ,right and straight side .All input signal data link with sldx file.
