Abstract
A control circuit generates a right-turn or left-turn signal from a direction indicator lamp based on a direction indicating signal from a turn signal switch in a scooter as a vehicle. The control circuit then calculates a turning angle of the scooter from an angular speed V of the scooter detected by an angular speed sensor, and cancels the turn signal generated from the direction indicator lamp on the condition that the turning angle be equal to or greater than a reference turning angle, that a vehicle speed N detected by a vehicle speed sensor be equal to or higher than a reference vehicle speed, and that the angular speed detected by the angular speed sensor be equal to or lower than a reference angular speed. Accordingly, even when the scooter is waiting to make a right or left turn at an intersection with a turning angle equal to or greater than the reference turning angle and an angular speed V equal to or lower than the reference angular speed, the vehicle speed N does not become equal to or higher than the reference vehicle speed (the vehicle speed is actually zero). Therefore, the turn signal is prevented from being canceled unnecessarily.
