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.
