Abstract
An automatic turn signal canceller of this invention is constituted using a geomagnetic sensor for detection of axial components of the geomagnetism (or magnetic field) and a conversion table storing relationships between bearings, inclinations, and outputs of the geomagnetic sensor, which are measured in advance. After the operator (or driver) of a motorcycle operates turn signals to indicate leftward or rightward turning of the traveling direction, the operator turns the traveling direction while inclining (or banking) the motorcycle. In this case, when the bearing of the motorcycle is varied by a prescribed angle (e.g., 20°) or more after the operator operates the turn signals, and then, the inclination of the motorcycle is restored to the normal position substantially perpendicular to the horizontal plane because the operator completely finishes turning the motorcycle, the turn signals are automatically canceled.
