A turn signal cancelling apparatus for a vehicle having a handlebar and a blinker unit which is operable to be activated by a manual operation and is operable to be deactivated by a cancelling signal. The apparatus comprises a handlebar turning angle detecting arrangement which detects the turning angle of the handlebar and provides a signal when the return angle of the handlebar exceeds a specified degree following turning operation of the vehicle, at least one of a time measuring arrangement which measures the time which elapses after the blinker unit has been activated and provides a signal when the specified time has elapsed, and a distance measuring arrangement which measure the travel distance of the vehicle after the blinker unit has been activated and provides a signal when the specified travel distance has been exceeded, and an output arrangement which provides the turn signal cancelling signal in response to at least one of the aforesaid signals, thereby providing an appropriate timing for automatically cancelling the turn signal of the vehicle.

Turn signal cancelling apparatus for use in vehicles

A circuit arrangement for automatically switching off the turn signal of a vehicle, e.g., a motorcycle. The turning angle of the handlebar of the motorcycle is detected electrically, i.e., it is neglected when the vehicle travels at a lower speed, and the maximum swing of the handlebar is memorized. In returning the handlebar to the center position, when the turning angle differs from the maximum swing by a predetermined value, a turn signal cancelling signal is produced, which is also used to reset the circuit so that the circuit responds correctly when the turn signal action is repeated successively.

Automatic direction indicator cancelling apparatus

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.
