Electronic Intelligent Turn Signal System 2006-01-0714

The directional turn signal is a vital safety feature, and when properly used by the motor vehicle operator, helps prevent countless collisions every day. As important as this safety feature is, its basic means of shut off control remains virtually unimproved since it was first invented more than 65 years ago. It is a mechanical, closed loop control system that still today exhibits functional circumstances where the turn signal either shuts off prematurely or fails to automatically shut off. This paper describes a patented, intelligent, computer controlled turn signal system with no moving parts that uses existing sensors on the vehicle to decide on a situation appropriate turn signal shut off point, thereby resolving nearly all of the turn signal control shortcomings of today’s mechanical method and improves vehicle safety at a potential overall cost savings.
