Project 1 (Mini Project on Vehicle Direction Detection
The image below is the snip of the overall subsystem.
As it shows two inputs steeringwheel_yawdegreeinput and Camerainput_Roadsign.
Inside it the two requirements are shown the first input is for requirement1 and second input is for requirement2.
Our overall output is Vehicle_Direction_Indicator.
The subsystem of requirement 1 is shown below.
As the input 1 comes the folllowing logic is applied.
According the initial values that are provided
The image below is requirement 2 model block.
Again the initial values are provided for the roadsign blocks.
Given below is the c code for the compleate model.
