An electrical translation circuit for detecting the initiation and termination of a turn or change in direction of a motorcycle, automobile, boat or other like vehicle and the cancellation of the turn indicator for that vehicle. Sensors detect relative steering angle, distance and velocity of the vehicle processing same to cancel a manually operated turn indicator. The detected change in steering angle is coupled with processed signals indicative of appropriate forward movement of the vehicle. The combined signals initiate a cancellation signal which will terminate the vehicle turn indicator signal. The vehicle turn indicator signal will not be reset until there has been an appropriate retracement of the steering angle coupled with appropriate forward movement of the vehicle thereby precluding inadvertent reset signals arising from lane changes or vehicle stoppage during the turning operation.

A self-cancelling apparatus for vehicle indicator signals for a vehicle having a rotating steering member which rotates relative to the vehicle frame and turn signal means selectively operable for activating and deactivating the vehicle turn signal means comprising: (a) steering angle sensor means for detecting the change in the relative angle between the rotating steering member and the frame of the vehicle; (b) angle sensor processing means for producing a binary electrical output signal having on and off states responsive to the change in the relative angle between the rotating steering member and the frame of the vehicle, said on state occurring when said change exceeds a predetermined angle, said off state occurring when the change does not exceed the predetermined angle, said angle sensor processing means being coupled to said steering angle sensor means; (c) distance sensor means for sensing the distance traveled by the vehicle, said distance sensor means being coupled to the vehicle; (d) distance sensor processing means for producing an electrical output signal responsive to a predetermined distance having been traveled by the vehicle, said distance sensor processing means being coupled to the distance sensor means; and (e) cancellation means for deactivating the turn signal means when the binary electrical output signal of said angle sensor processing means has switched from the on to the off state and the electrical output signal of said distance sensor processing means coincides with the off state, said cancellation means being coupled to the outputs of said angle sensor processing means and said distance sensor processing means.
