Are there any suggestions/tutorials on making self parking parallel car

Hi! I'm new to both raspberry pi and coding. However, teacher assigns me to make self parking parallel car and give me a week for this project, which I have no clue on how to do it. Any suggestion?

Begin with what sensors do you need. Then start to write a flow chart over how it should work so you can divide the project into smaller parts (functions). Start to writing simple functions and determine how you can verify that they work. Combine the functions into a complete program.

I call the method "How to eat an elephant", In small pieces.

Thank you!
