Project Overview

•System provides automated parallel and perpendicular parking services

•Designed to provide a safer parking experience▫Eliminates human error in parking▫Facilitates steering, acceleration, and

braking▫Provides simple, easy-to-use interface

Overview of Features

•Automated parallel or perpendicular parking

•Ultra-sonic sensors on all sides to measure space availability

•Cameras on front and rear to provide live view to customer

•Ultrasonic sensors and camera work together to detect and prevent collision

Overview of Features (cont.)

•Options for driver to terminate process before completion

•System memory to immediately continue parking process after interruption without need for reassessment

Overview of Features (cont.)• Human Machine Interface for system interaction• Convenient use through touch screen menus• Highlights potential parking spaces• Displays system warnings to user

• Safety Features• Avoids collisions with obstacles detected while

system is active• System timeout to prevent malicious use• Seed and key subsystem communication

Domain Research

• Investigated active park assist systems currently available on the market

• Researched potential security vulnerabilities for current embedded systems

• Needed to apply domain knowledge to embedded system design and application

Project Constraints

• Vehicles with shift by wire transmission only

• Failure of any hardware component disables uses of APA system

• System must avoid collision with obstacles detected by sensors during parking maneuvers

• Once system initiated, process must be completed within 75 seconds

▫Successful parallel parking

▫User aborts maneuver by braking

▫Obstacle encountered

Successful Parallel Parking

User Aborts Maneuver By Braking

Obstacle Encountered - Timeout
