Abstract
PURPOSE:To perform suitable automatic cancelling in a winker cancelling system of a motorcycle by processing the staggering in the low speed as a noise and detecting the predetermined steering handle angle and returning angle. CONSTITUTION:When changing the direction in the predetermined speed condition the ON time proportion of a semiconductor 5 becomes larger and the output of a noise elimination circuit B follows up the output of a sensor 1 and is compared with the set potential at amplifiers 18 and 19. When it exceeds the preset angle the output of an amplifier 22 becomes low level to discharge a capacitor 25 and becomes high level to start charging when the handle is returned, said charging current turning on transistors 26 and 27 to transmit a cancelling signal. When the handle staggers in low speed condition the signal is attenuated due to larger time constant of an integrating circuit 8 as the ON time proportion of the switch is small and the signal is eliminated as a noise.
