PURPOSE:To accurately perform automatic release of a winker in the captioned device suitable for an autobicycle, by deciding if cornering operation is regularly started or not through the first reference and deciding if the cornering operation is ended or not through the second reference. CONSTITUTION:When an autobicycle turns, for instance, to the left at an intersection or the like, a winker switch is turned on, if cornering operation is started, a handle becomes unsteady generally in a speed down vehicle. Then an output of a steering angle sensor 1 is increased larger than the first preset value to start operation of an integration circuit 11, at each time a pulse is generated from a distance sensor 1, a value of handle steering angle is latched and integrated. And then the cornering operation advances, if an integrated value of said steering angle becomes larger than the second preset value, an output is generated from a comparator 14, further the cornering operation is completed, if an output of a comparator 9 becomes ''0'', a winker cancelling signal S1 is output from a driver circuit 16. |
