Abstract
PURPOSE:To enable not to be cancelled by a momentary reverse steering by a method wherein a winker is cancelled when an actuation direction of the winker is identical with a direction of an actual course changing, in a winker cancellation device applying terrestrial magnetism sensor. CONSTITUTION:Signals X and Y of a terrestrial magnetism sensor 11 passing through an amplifier 12 and sample hole circuits 13 and 13' measure a slewing angle at a differential amplifier 15 and 15' and generate a cancellation signal at comparators 16 and 16'. On the other hand, the signals X and Y being differentiated at operation circuits 21 and 22 passing through a code discrimination circuit 23 enter into a decision circuit causing an H level only when an actuation direction of a winker switch 14 is identical with a direction of an actual course changing, the foregoing cancellation signal passes through an OR gate 19 and an AND gate 20 causing an L level when foregoing directions are not identical each other, and the cancellation signal blocks the signals at the AND gate 20 causing not to cancel by a momentary reverse steering due to road conditions.
