Abstract
PURPOSE:To remove the influence of the variation of latitude in an automatic winker cancel device for an autocycle by obtaining a bearing difference equivalent value by a formula noted in a separate paragraph on the basis of outputs from a pair of earth magnetism sensors. CONSTITUTION:Signals VX and VY from a bearing sensor 1 are smoothed in an amplifier 2. One is converted into beforeturnabout bearing signals VXO and VYO and another is inputted directly into an arithmetic unit 4, where a computation by the formula noted in a separate paragraph is carried on for obtaining a turning angle equivalent value for a car. This signal is compared with the set value in a setter 7 by a comparator 6, and operates a winker relay via an output circuit 8 as a cancel signal. This turning angle equivalent value is perfectly free from the influence of the variation of earth magnetism according to latitude.
