PURPOSE:To keep of any danger due to being oblivious of operation on a signal switch, by putting the turn signal switch back to OFF after making sure that a car gets through a curve and its onward movement in a state of going straight ahead becomes a constant distance. CONSTITUTION:Putting a steering wheel back in its place, when a car goes straight ahead, a signal out of a steering angle sensor 18a builds up to a high level from low and is inputted into a clock of a D type flip-flop 41, then transmitted to an output Q and a Q bar whereby the Q becomes a high level, opening a gate 58. Next, signal processing takes place in the order of a distance sensor 17 a circuit 59 a line 60 a circuit 58 a line 61, and a distance signal of the line 61 is inputted into the clock of a counter 56 and performs its count motion. And, the output Q if a circuit 66 is held at a high level for a specified time long with a time constant to be obtained with a resistance 67 and a condenser 68, while an electric current is made to flow in solenoids 10 and 11, bringing a winker lever back to a neutral point, and a turn signal switch 15 is turned off, thus blinking in winker lamps 13 and 14 is stopped. |
