Turn signal systems and methods
First Claim

1. A method for controlling a turn signal stalk, comprising:
- determining with a controller whether a turn signal stalk is being activated toward a turn signal position;
determining whether an object is in a blind spot by sensing signals sent from one or more sensors directly or indirectly to the controller;
determining whether a warning signal is required to be supplied directly or indirectly by the controller to the turn signal stalk;
determining whether the turn signal lever has reached a turn signal position for a turn signal function;
setting a timer for a predetermined period of time;
monitoring a steering wheel rotation signal sensor to determine whether the turn signal function requires cancelling;
determining whether the predetermined period of time has elapsed; and
reducing an electromagnetic brake by the controller, thereby allowing the turn signal stalk to return to a neutral position in a controlled manner.

Abstract
Methods and systems are provided pertaining to a turn signal. AUTO CANCEL of a turn signal may be performed electrically, eliminating cancelling pawls and undesirable noise emanating from such pawls as they click against conventional structure in predominantly mechanical turn signal systems. An electromagnetic brake may dampen or prevent turn signal stalk movement if an object is in a blind spot of a vehicle. Such brake may be released or canceled electronically and quietly.
