〔産業上の利用分野〕
本発明は自動車の安全走行にかかわり、特にいねむり運
転やわき見運転時の警告に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to safe driving of automobiles, and particularly to warnings when driving while asleep or distracted.

転に対する反応を調べ１反応かにぷい場合にはいねむり
状態にあるか、又は運転に集中していない状態にあると
判断して警報すること等を特徴としていた。The conventional invention examines the driver's reaction to driving based on the way the driver presses the accelerator or brake, grips the steering wheel, turns the steering wheel, etc. If the driver's reaction is negative, it indicates that the driver is asleep or unable to drive. It was characterized by the ability to issue an alarm when it determined that the user was not concentrating.
従来の方法は間接的にいねむりやわき見運転等を検出し
ていたが１本発明は目の方向や車の速度と連動した視野
、目の開き具合を直接観測することを特徴とする。Conventional methods have indirectly detected sleepiness, distracted driving, etc., but the present invention is characterized by directly observing the visual field and the degree of eye opening in conjunction with the direction of the eyes and the speed of the vehicle.

十分かどうかを識別することにより達成される。The above purpose is to install an optical receiver that can monitor the driver's eyes in front of the driver's seat, convert this optical signal into an electrical signal, input it to a processing device along with the speed of the car, and use this processing device to determine the direction of the driver's eyes. This is achieved by identifying how far away from the normal direction the vehicle is ahead, whether the field of view estimated from the speed of the car and the direction of the eyes is in a range that can sufficiently capture information ahead, and whether the eyes are wide enough. be done.

を判定する指標として作用する。(Function) The direction of the driver's eyes, the field of view, and the degree of eye opening function as indicators for determining whether or not the driver is driving distracted or dozing off.
以下本発明の一実施例を第１図〜第５図により説明する
。An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

をゆるやかにかける。This output is converted into electricity as shown by block 2, converted into digital by AD conversion shown in 3, and input to the computer shown by 4. Here, if the process shown in Figure 2 is performed and drowsy driving or distracted driving is detected, the first
As shown in 5.6.7 of the figure, display Alarm 1 and apply the automatic brake gently.

上かどうか判定する。Fig. 2 shows the judgment unit, which judges whether the eyes are facing forward in the correct direction. The deviation of the eye from the normal front center line can be determined by whether or not it is more than a certain range away from the normal front center line. It also recognizes the vehicle's speed and field of view and determines whether it is above a certain range.

If even one of the three recognition/judgments is out of the normal range, a warning will be displayed if the time exceeds a certain value, and if the time between the warning and display exceeds a certain value, the brakes will be applied gently. is automatically applied to decelerate.
第３図は眼の視野を前方、方向及び上方向から見た図で
ある。（ａ）は前方方向からみた図、（ｂ）は横方向、
（Ｑ）は上方向から見た図である。FIG. 3 is a view of the visual field of the eye seen from the front, direction and top. (a) is a view from the front direction, (b) is a view from the side,
(Q) is a view seen from above.
正規の場合には、正規前方方向線００′に対し、視野は
ＡＢＣＤのようになる。又車の速度が速くなった場合に
はＡ’ Ｂ’ Ｃ’ Ｄ’のように狭くなる。In the normal case, the field of view is ABCD with respect to the normal forward direction line 00'. Also, when the speed of the car increases, it becomes narrower like A'B'C'D'.
これに対して第４図はわき見運転をしているため眼かむ
かつて左の方に向いている場合の視野を示している。正
規前方方向線ｏＯ′から大きくずれており前方から見た
眼の視野が狭くなっている。On the other hand, Figure 4 shows the field of view when the driver is looking to the left, causing his eyes to bite due to distracted driving. It deviates greatly from the normal forward direction line oO', and the visual field of the eye seen from the front is narrowed.

断できる。Also, Figure 5 shows a case where you look down when driving while asleep, etc., and the field of view is narrow and the center line of the eye is significantly deviated from the normal case.A case of 0 or more is an example, but the direction of the eye is The degree of deviation from the correct forward direction can be determined from the field of view and the degree of eye opening, and from this, the state of distracted driving or sleepy driving can be determined.
