PURPOSE:To enable the completion of corner passage to be certainly discriminated by setting the dynamic center angle of a steering handle and comparing the threshold value with the multiplied value of the angular difference between the dynamic center angle thereof an each instantaneous steering handle angle, when a car passes through a corner. CONSTITUTION:In an apparatus in which a winker 6 is flashed via a processing unit 5 when a winker switch 1 is set, and on the contrary the winker 6 is turned off when a clear switch 2 is set, the processing unit 5 receives also both a distance pulse (b) from a speed sensor 3 and a steering handle angle signal (a) from an angle sensor 4. While a car runs a specified distance, a steering handle angle within a specified range is set as a dynamic center angle of the steering handle and the difference between the center angle and an instantaneous steering handle angle is compared with the first threshold. Thereafter, the multiplied value of the angle differences which exceed the threshold is compared with the second threshold and the winker 6 is controlled to be lighted off, by discriminating that passing through a corner is completed when the multiplied value exceeds the second threshold value. |
