Abstract

PURPOSE:To make the automatic resetting of a turnsignal attainable with accuracy and certainty, by installing an angle detecting device which turns on or off the turn signal in an electrical manner at a fixed angle on the basis of a steering wheel reference position, while resetting the signal in time of being put back in its place below the fixed angle. CONSTITUTION:Coming nearer to an intersection point, when a turn signal switch is turned to a side 28b, a turn signal lamp 29 is turned on, while the output S5 of a turn signal detecting part 6 comes to H. And, with wheel steering, when a shield plate 10 of a speed detector 1 rotates more than 5 deg. from a reference position, a lead switch 8 is turned on as well as when the steering wheel is put back within a range of 5 deg. after turning, the switch 8 is turned off, making the turn signal switch 28 go back to neutral via FF14 and 15 of a control element 3 and a solenoid 26 of a detecting device 5. In this connection, when a fact that a car is below the fixed speed is detected by the detecting device 5, an automatic resetting control device 2 is made into being unworked so that irregular working is obviated. Thus, even if a working angle in the steering wheel is minimal, a turn signal can be automatically reset with accuracy and certainty.

ある。(Prior Art) An automatic return device for a direction indicator of a vehicle, such as a four-wheeled vehicle, usually employs a mechanical system. The principle of this method is that when the direction indicator lever located near the handle is operated from the non-operating position (neutral position) to the operating position for pointing left or right, the direction indicator lever is mechanically locked. The direction indicator switch that causes the direction indicator to flash is turned on, and the lock is mechanically released when the steering wheel is rotated in the direction of turning left or right and returning to the original reference position (going straight), For example, the direction indicator lever is returned to a non-operating position by the action of a spring.

しかしながら、このような機械的方式は第１に方向指示

が同じ車両（微小ストロークで制御する必要のある車両
）には採用することができない欠点をもつ。However, in such a mechanical system, firstly, the locking and unlocking mechanism of the direction indicator lever is based on a mechanical structure, so it is necessary to lengthen the operating stroke.
In practice, it can only be applied to vehicles such as four-wheeled vehicles that have a steering wheel that requires a turning angle several times the steering angle of the wheels. It has the disadvantage that it cannot be used in the same vehicle (vehicle that requires control with minute strokes).

し直さなければならない欠点がある。Second, since the direction indicator lever is unlocked directly by turning the steering wheel, for example, after the direction indicator lever is operated from the non-operating position to the operating position while the vehicle is running, it can be activated at a signal, etc. Even though it is necessary to hold the direction indicator lever in the operating position when the vehicle is stopped and the steering wheel is turned back, the steering wheel cannot be turned. The disadvantage is that the lever also automatically returns to the non-operating position, and the driver has to operate the direction indicator lever again.

任意で例えば５　ｋｍ／Ｈに選定することができる。That is, by connecting the speed detecting means 5, it is possible to detect that the vehicle speed is below a certain level and prevent the control means 2 from operating, thereby preventing irregular operation. A so-called speed sensor consisting of a reed switch 42 and a magnet 43 disposed near this and rotating in the direction of arrow B in synchronization with the vehicle speed integrates the pulse signal generated by opening and closing of this reed switch 42. An integrator circuit includes resistors 44 and 45 and a capacitor 46, and a comparator circuit includes a converter 49 that divides the voltage with resistors 47 and 48 and compares this reference voltage with the output of the integrator circuit. By supplying the output S6 of this comparison circuit to the D input of the FF 14, the output S6 of the converter 49 is "H" when the vehicle speed is higher than a constant vehicle speed (hereinafter referred to as the set speed), and the vehicle speed is lower than the constant vehicle speed. When , select so that rLj. This set speed can be arbitrarily selected, for example, to 5 km/h.

次に、斯かる速度検出手段５を付加した場合における自
動復帰装置の動作について説明する。Next, the operation of the automatic return device when such speed detection means 5 is added will be explained.

先ず、車両が設定速度よシ大きい車速で走行している場
合には上述した如く速度検出手段５の出力Ｓ６はＩＨｊ
となり、この結果、ＦＦ１４のＤ入力はｒＨＪとなる。First, when the vehicle is running at a speed greater than the set speed, the output S6 of the speed detection means 5 is IHj as described above.
As a result, the D input of the FF 14 becomes rHJ.

したがって、直進走行、或いは右左折走行いずれに於て
も設定速度以上を維持している限、ｊ２ＦＦ１４のＤ入
力はｒＨＪに維持されるため、既に説明した自動復帰動
作をそのまま行うことになる。Therefore, as long as the set speed or higher is maintained whether the vehicle is traveling straight or turning right or left, the D input of the j2FF 14 is maintained at rHJ, so the automatic return operation described above will continue as is.

したがって既に説明した如＜ＦＦ１４のＤ入力がｒＨｌ

以下に減速した状態に於てはコンパレータ４９の出力は

持され自動復帰動作は行われない。Therefore, as already explained, the D input of FF14 is rHl.
If the direction indicator 27 is held at the same speed, the automatic return operation of the direction indicator 27 will be performed at this point, but if the speed is temporarily stopped or the speed is decelerated below the set speed, the output of the comparator 49 will not be rLJ. , since the D input of the FF 14 becomes rLJ, this Q output is held at rLJ due to the function of the D-FF, and no automatic return operation is performed.

そして、この後車両を走行させ設定速度より犬きく加速

になる。After this, when the vehicle is driven and the vehicle accelerates much faster than the set speed, the turn signal 27 will remain in the state of ``'', and if you perform the specified left/right turn turn operation: An automatic return will be performed.

ことができる。In such an embodiment, for example, when the vehicle speed is reduced and the vehicle is stopped temporarily, the automatic stop operation of the direction indicator can be temporarily stopped. Note that the set speed can be arbitrarily set by adjusting the voltage dividing resistors 47 and 48. Further, although the speed sensor is constructed by magnetic means in the embodiment, it can be replaced by other constructions such as the optical means described above.

装置として提供することができる。(Effects of the Invention) The automatic return device for a direction indicator according to the present invention can extract the turning angle of the steering wheel in a non-contact manner and as an electrical signal, so that the turning angle of the steering wheel can be detected by a minute stroke. It is possible to accurately and reliably detect the angle even when the angle is detected, and can be fully applied to vehicles such as motorcycles where the turning angle of the steering wheel is minute. Also, since the angle detection signal is electrical, D-FF 21

技術的効果を奏する。Furthermore, by controlling the automatic return operation using the speed detection means, stable operation is ensured without causing the automatic return device to operate irregularly even if the steering wheel sways, for example when stopped temporarily at an intersection. This has numerous technical effects, such as eliminating the inconvenience of having to operate the direction indicator lever again when turning left or temporarily stopping.
