Abstract
There is disclosed herein a turn signal system for vehicles wherein the turn signal is automatically cancelled upon the steering device of the vehicle being returned to a predetermined position. The system is particularly applicable to motorcycles. The system includes a sensor which generates a signal representing a steering angle corresponding to the operation of the steering device, a noise eliminating circuit which receives the sensor signal and eliminates noises included in this signal as a function of running speed of the vehicle. A peak hold circuit receives the output signal from the noise eliminating circuit and holds the peak value of the signal, and a comparator receives the output signal of the noise eliminating circuit as well as the output of the peak hold circuit, and compares these signals to generate a turn-signal cancelling signal when the steering device has been returned by a predetermined amount toward its normal position.
