• System provides the ability of Autonomous Steering with an override capability to allow Normal Control of the vehicle.
• Motivation for project– Proximity Sensors, Torque Sensors,
Interpolation Table, and various system checks.
– Traffic Jam Assist, Park Assist, Lane Correction Assist, and Emergency Object Avoidance Assist.
Project Overview
• Ramp down Autonomous Control upon the driver applying torque.
• Override Autonomous Control.
• Ability to update software.
• Secure data transfer through CAN bus.
• Alert user up upon failure.
Overview of Features
• Investigated CAN bus and power steering controller
• Needed to apply domain knowledge on ECU communications and how a power steering system operates
• Project Constraints– Safety override– System security– Communication Speed
