自動車の運転者は、自動車の運転中、前車がブレーキを作動させてブレーキラ ンプが点灯したこと又は信号機が赤信号を表示したことを確認したときには、直 ちに自己の自動車を減速させ若しくは停止させる必要がある。しかるに、運転者 の前方不注意等により前車のブレーキランプ又は赤信号の発見が遅れることもあ り得る。このようなブレーキランプ又は赤信号の発見の遅れは追突事故、衝突事 故等の原因となることがあり、極めて危険である。もとよりブレーキランプ又は 赤信号の発見の遅れを防止するために運転者は常に前方を注意深く目視すべきこ とは当然であるが、本考案は、運転者による前車のブレーキランプ又は赤信号の 発見が遅れるという万一の場合に備えて、前車のブレーキランプ又は赤信号の赤 色光を検知し、運転者に警報を与える機能を自動車に備えさせようとしてなされ たものである。 While driving a car, the driver of the car may immediately decelerate his or her vehicle when he or she confirms that the preceding vehicle has applied the brakes and the brake lamp has lit up or that the traffic light has displayed a red traffic light. Need to stop. However, the driver's carelessness in front of the driver may delay the detection of the brake lamp or red signal of the preceding vehicle. Such a delay in discovering the brake lamp or red traffic light may cause a rear-end collision, a collision, or the like, and is extremely dangerous. Of course, it is natural that the driver should always look carefully ahead in order to prevent the delay in finding the brake lamp or the red signal.However, the present invention enables the driver to detect the brake lamp or the red signal in the front vehicle. It was designed to equip the vehicle with a function to detect the brake lamp of the preceding vehicle or the red light of the red signal and give a warning to the driver in case of a delay.

【0008】[0008]

【作用】[Action]

請求項1の赤色光検知装置付きバックミラーにおいては、自動車の運転中、前 車がブレーキを作動させて赤色のブレーキランプを点灯させたとき又は信号機が 赤信号を点灯させたときには、赤色光検知装置が当該ブレーキランプ又は赤信号 の赤色光を検知する。該赤色光の強度があるしきい値を越えたときには警報装置 を作動させて運転者に警報を与える。赤色光検知装置が赤色光を検知しても該赤 色光の強度がしきい値を越えないときには警報装置は作動しない。 In the rearview mirror with a red light detecting device according to claim 1, when the front vehicle operates a brake to turn on a red brake lamp or a red light is turned on by a traffic light, the red light detection is performed while the vehicle is driving. The device detects the brake lamp or the red light of the red signal. When the intensity of the red light exceeds a certain threshold value, an alarm device is activated to give an alarm to the driver. Even if the red light detecting device detects red light, if the intensity of the red light does not exceed the threshold value, the alarm device does not operate.

【0009】 請求項2の赤色光検知装置付きバックミラーにおいては、前記しきい値のレベ ルは可変であって、夜間については昼間よりも前記しきい値が高く設定される。 即ち、夜間においては走行するすべての自動車がブレーキランプよりも強度の小 さい赤色光の尾灯を点灯させているのであるから、赤色光検知装置が前車の尾灯 の赤色光を検知しても警報装置を作動させないようにすると共に赤色光検知装置 が尾灯の赤色光よりも強度の大きい前車のブレーキランプの赤色光を検知したと きに警報装置を作動させるようにするために、夜間については昼間よりも前記し きい値を高くする必要があるのである。In the rearview mirror with a red light detecting device according to a second aspect, the level of the threshold value is variable, and the threshold value is set higher at night than at daytime. In other words, at night, all the cars that are driving turn on the red light tail light, which is less intense than the brake lights, so even if the red light detection device detects the red light from the tail light of the preceding vehicle, an alarm is issued. In order to prevent the device from operating and to activate the alarm device when the red light detection device detects the red light of the brake light of the front vehicle, which has a higher intensity than the red light of the taillight, at night, It is necessary to raise the threshold value higher than during the daytime.

【0010】 請求項3の赤色光検知装置付きバックミラーにおいては、前車のブレーキラン プ又は赤信号の赤色光は光電子増倍管により検知されるが、光電子増倍管は多段 増幅の機能を有するため、微弱光も確実に検出される。In the rearview mirror with a red light detecting device according to claim 3, the brake lamp of the front vehicle or the red light of the red signal is detected by the photomultiplier tube, but the photomultiplier tube has a multistage amplification function. Since it has, weak light can be reliably detected.

【0011】 請求項4の赤色光検知装置付きバックミラーにおいては、運転者に対する警報 は視覚表示と聴覚表示の両方により行なわれるので、前車がブレーキを作動させ たこと又は信号機が赤信号を表示したことが運転者により確実に伝えられる。In the rearview mirror with a red light detecting device according to claim 4, since the warning to the driver is given by both the visual display and the audible display, the preceding vehicle has actuated the brake or the traffic signal displays a red signal. The driver can be surely told that he / she did.

【実施例】【Example】

次に、本考案の実施例を添付図面に従って説明する。 図1は本考案をドアミラーに適用した事例を示す。同図において、符号1はミ ラーボデー、2はミラー、3はミラー2の角度を調節するためのアクチュエータ である。ミラーボデー1の前部(車輌の前方に面した部分)には開口部4を形成 し、該開口部4に干渉フィルター5を嵌め付ける。干渉フィルター5は赤色光の みを透過させるものを使用する。開口部4の近傍には光電子増倍管(PM管)6 をその受光部7を開口部4に臨ませた状態で配設する。8は光電子増倍管6の取 付具である。 Next, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an example in which the present invention is applied to a door mirror. In the figure, reference numeral 1 is a mirror body, 2 is a mirror, and 3 is an actuator for adjusting the angle of the mirror 2. An opening 4 is formed in the front part of the mirror body 1 (the part facing the front of the vehicle), and an interference filter 5 is fitted into the opening 4. The interference filter 5 used is one that transmits only red light. A photomultiplier tube (PM tube) 6 is arranged in the vicinity of the opening 4 with its light receiving portion 7 facing the opening 4. Reference numeral 8 denotes a fixture for the photomultiplier tube 6.

【0013】 図2は赤色光を検知し、運転者に警報を与える手段の説明図である。干渉フィ ルター5を透過した赤色光は光電子増倍管6等の光検知部11により検知される 。赤色光を検知した光検知部11は信号を発し、該信号は増幅部12により増幅 される。昼夜のしきい値レベルを決定する前段階で周囲光を検知しておき、昼夜 の判断を行なうと共に周囲光レベルを基準としてしきい値レベルを決定する(基 準レベル変換13)。因みに、昼間の周囲光レベルは夜間の周囲光レベルよりも 高く、また、しきい値と周囲光レベルとの差は昼間よりも夜間の方が大きい。続 いて、警報を発すべき警報出力レベルを昼間と夜間とで格別にセットする(符号 14)。即ち、夜間については、警報を発すべき警報出力レベルを昼間よりも高 くセットする。光検知部11が発し、増幅部12により増幅された信号が警報を 発すべき警報出力レベルに達しているか否かを警報出力判別部15に判別させ、 該信号が警報を発すべき警報出力レベルに達しているときには視覚表示16と聴 覚表示17とにより運転者に警報を発する。一方、該信号が警報を発すべき警報 出力レベルに達していないときには、警報は発しない。視覚表示16による警報 としては例えば自動車内の警報ランプを点滅させ、聴覚表示17による警報とし ては例えば自動車内のブザーを鳴らすものとする。FIG. 2 is an illustration of means for detecting red light and giving a warning to the driver. The red light transmitted through the interference filter 5 is detected by the photodetector 11 such as the photomultiplier tube 6. The light detection unit 11 that has detected the red light emits a signal, and the signal is amplified by the amplification unit 12. Ambient light is detected before the threshold level is determined for day and night, the day and night are determined, and the threshold level is determined based on the ambient light level (reference level conversion 13). Incidentally, the ambient light level in the daytime is higher than the ambient light level in the nighttime, and the difference between the threshold value and the ambient light level is larger in the nighttime than in the daytime. Next, the alarm output level at which an alarm should be issued is set specifically for daytime and nighttime (reference numeral 14). That is, at night, the alarm output level for issuing an alarm is set higher than during daytime. The photodetector 11 emits the signal, and the signal amplified by the amplifier 12 causes the alarm output discriminating unit 15 to discriminate whether or not the signal has reached the alarm output level at which the alarm should be issued. When it has reached, the visual display 16 and the audible display 17 alert the driver. On the other hand, when the signal does not reach the alarm output level at which the alarm should be issued, the alarm is not issued. For example, the warning by the visual display 16 may be a blinking alarm lamp in the vehicle, and the warning by the auditory display 17 may be a buzzer in the vehicle.

【考案の効果】[Effect of the device]

以上説明したように、本考案によれば、自動車の運転中、前車がブレーキラン プを点灯させ又は信号機が赤信号を点灯させたときには、当該ブレーキランプ又 は赤信号の赤色光を赤色光検知装置が検知し、運転者に警報を与える。従って、 万一運転者が不注意等により前車のブレーキランプ又は赤信号に気付かなかった 場合でも、運転者は警報によりこれを知ることができるため、直ちに減速、停車 等の措置をとることにより追突事故等を防止することができる。 As described above, according to the present invention, when the front vehicle turns on the brake lamp or the traffic light turns on the red signal while the vehicle is driving, the brake lamp or the red light of the red signal is changed to the red light. The detection device detects and gives an alarm to the driver. Therefore, even if the driver does not notice the brake light or red light of the preceding vehicle due to carelessness etc., the driver can know this by the alarm, so by immediately taking measures such as deceleration and stopping. A rear-end collision can be prevented.

【0015】 赤色光検知装置を自動車の左右両側のバックミラーに備えさせたときには、前 車のブレーキランプ又は赤信号の赤色光を加算的に捉えることができる。即ち、 自動車の左右2ヶ所で赤色光を受光するため、赤色光は短時間で且つ高い精度で 検知される。When the red light detecting device is provided on the left and right rearview mirrors of the vehicle, the brake light of the front vehicle or the red light of the red signal can be additionally captured. That is, since red light is received at two places on the left and right of the automobile, the red light can be detected in a short time with high accuracy.
