Automatic direction indicator cancelling apparatus

摘要

A circuit arrangement for automatically switching off the turn signal of a vehicle, e.g., a motorcycle. The turning angle of the handlebar of the motorcycle is detected electrically, i.e., it is neglected when the vehicle travels at a lower speed, and the maximum swing of the handlebar is memorized. In returning the handlebar to the center position, when the turning angle differs from the maximum swing by a predetermined value, a turn signal cancelling signal is produced, which is also used to reset the circuit so that the circuit responds correctly when the turn signal action is repeated successively.
