【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して説明する。
【0010】
図1は、本実施の形態に係る車両用警報装置が接続されている電動リトラクタ100の構成を示す図である。
【0011】
電動リトラクタ100はフレーム1を備えている。このフレーム1にはシートベルトを巻き取るリールシャフト3が回転自在に設置され、車両に所定の減速度が作用したとき又はシートベルトが所定の加速度で引き出されたときにシートベルトの引き出しをロックする公知のシートベルトロック機構2が固定されている。
【0012】
次いで、リールシャフト3の中心軸3aはリールシャフト用プーリ5の中心軸に連結されており、このリールシャフト用プーリ5は動力伝達ベルト7を介して直流モータ用プーリ6に接続されている。
【0013】
リールシャフト用プーリ5及び直流モータ用プーリ6の外周にはそれぞれ所定数の外歯が形成され、また動力伝達ベルト7の内周にも所定数の内歯が形成されており、リールシャフト用プーリ5及び直流モータ用プーリ6の外歯と動力伝達ベルト7の内歯とはそれぞれ過不足なくかみ合っている。
【0014】
直流モータ用プーリ6の中心軸は直流モータ10に連結されている。従って、直流モータ10の回転は直流モータ用プーリ6を介してリールシャフト3に伝達される。
【0015】
直流モータ10は、フレーム1に少なくとも2点以上で固定されており、また直流モータ駆動部11を介してMPU(Micro Processing Unit)14に接続されている。直流モータ駆動部11はMPU14からの制御信号に基づいて直流モータ10の回転を制御する。
【0016】
MPU14は、時間を計るタイマ15を備えており、シートベルトの装着の有無を検出するシートベルト装着有無検出部16及び車両が後方から接近してくる場合に警報を発する車両用警報部20に接続されている。
【0017】
図2は車両用警報部20の構成を示す図である。車両用警報部20は、後方から接近してくる車両を検出する右側後方検出超音波センサ21及び左側後方検出超音波センサ22と、これらの超音波センサの出力から車両が接近しているか否かを検出する車両接近検出部23と、車両接近検出部23及びシートベルト装着有無検出部16の出力から警報を発するか否かの判断を行い、この判断結果に応じて警報を発する警報判断及び警報発生部24を備えている。
【0018】
右側後方検出超音波センサ21は車両後部の右角部に設けられており、左側後方検出超音波センサ22は車両後部の角部に設けられている。図3は右側後方検出超音波センサ21及び左側後方検出超音波センサ22の測距範囲を示している。右側後方検出超音波センサ21及び左側後方検出超音波センサ22は、図3中の測距範囲に含まれる車両等の障害物までの距離を超音波の発信から障害物に反射して戻ってくるまでにかかる時間から求め、該障害物までの距離に応じた距離信号を車両接近検出部23に出力する。
【0019】
車両接近検出部23は右側後方検出超音波センサ21及び左側後方検出超音波センサ22から出力された距離信号の時間的変化から障害物が接近しているか否かを判別し、接近の有無に応じた信号を警報判断及び警報発生部24に出力する。
【0020】
シートベルト装着有無検出部16は、シートベルトの装着の有無を検出し、シートベルトの装着の有無に応じた信号を警報判断及び警報発生部24に出力する。
【0021】
警報判断及び警報発生部24は、シートベルト装着有無検出部16から出力された信号に基づいてシートベルトが装着状態から非装着状態になったことを検知したときに、車両接近検出部23から出力された信号を検出する。さらに、警報判断及び警報発生部24は、シートベルトが装着状態から非装着状態になった座席が運転席、助手席、後部右側座席、後部中央座席及び後部左側座席のいずれであるかを判断する。そして、警報判断及び警報発生部24は、後方から接近してくる車両があり、かつ車両が接近してくる位置(左右)とシートベルトが装着状態から非装着状態になった座席の位置(左右)とが共通する場合に警報を発する。シートベルトが装着状態から非装着状態になった座席が後部中央座席の場合には左右のどちらに車両が接近してきても警報を発する。
【0022】
上述したように、本実施の形態によれば、警報判断及び警報発生部24は、後方から接近してくる車両があり、かつ車両が接近してくる位置(左右)とシートベルトが装着状態から非装着状態になった座席の位置(左右)とが共通する場合に警報を発するので、乗員が車両のドアを開く前に危険を認識することができる。
【0023】
本実施の形態の車両用警報部20は、駐車している場合などで同時に左右後方から車両が接近してくる場合にも適用でき、シートベルトが装着状態から非装着状態になった座席が同時に複数ある場合にも適用できる。
【0024】
尚、本実施の形態では、車両用警報装置として電動リトラクタ100に接続されているシートベルト装着有無検出部16及び車両用警報部20を使用したが、車両用警報装置は、シートベルト装着有無検出部16及び車両用警報部20を備えていればよく、電動リトラクタ100に接続されていなくてもよい。
【0025】
【発明の効果】
以上詳細に説明したように、請求項1の車両用警報装置によれば、乗員を拘束するシートベルトの装着の有無が検出され、乗員の座席の位置が検出され、右側後方から接近してくる車両までの距離の検出結果から当該車両の接近が判別され、左側後方から接近してくる車両までの距離の検出結果から当該車両の接近が判別され、シートベルトが装着状態から非装着状態になり、かつ、乗員の座席の位置が右側であり、かつ、右側後方から車両が接近するときに警報を発すると判断され、この判断結果に応じて乗員に対して警報が発されるので、後方から車両が接近する側の乗員が車両のドアを開く操作を行う前に右側後方から確実に接近する車両に対する危険性を確実に認識することができる。

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
FIG. 1 is a diagram showing a configuration of an electric retractor 100 to which a vehicle alarm device according to the present embodiment is connected.
[0011]
The electric retractor 100 includes a frame 1. A reel shaft 3 that winds up the seat belt is rotatably installed on the frame 1, and the drawer of the seat belt is locked when a predetermined deceleration acts on the vehicle or when the seat belt is pulled out at a predetermined acceleration. A known seat belt locking mechanism 2 is fixed.
[0012]
Next, the central shaft 3 a of the reel shaft 3 is connected to the central shaft of the reel shaft pulley 5, and the reel shaft pulley 5 is connected to the DC motor pulley 6 through a power transmission belt 7.
[0013]
A predetermined number of external teeth are formed on the outer periphery of each of the reel shaft pulley 5 and the DC motor pulley 6, and a predetermined number of internal teeth are also formed on the inner periphery of the power transmission belt 7. 5 and the external teeth of the DC motor pulley 6 and the internal teeth of the power transmission belt 7 are engaged with each other without excess or deficiency.
[0014]
The central axis of the DC motor pulley 6 is connected to the DC motor 10. Accordingly, the rotation of the DC motor 10 is transmitted to the reel shaft 3 via the DC motor pulley 6.
[0015]
The DC motor 10 is fixed to the frame 1 at at least two points, and is connected to an MPU (Micro Processing Unit) 14 via a DC motor driving unit 11. The DC motor drive unit 11 controls the rotation of the DC motor 10 based on a control signal from the MPU 14.
[0016]
The MPU 14 includes a timer 15 that measures time, and is connected to a seat belt wearing presence detecting unit 16 that detects whether a seat belt is worn and a vehicle warning unit 20 that issues a warning when the vehicle approaches from behind. Has been.
[0017]
FIG. 2 is a diagram showing a configuration of the vehicle alarm unit 20. The vehicle alarm unit 20 includes a right rear detection ultrasonic sensor 21 and a left rear detection ultrasonic sensor 22 that detect a vehicle approaching from the rear, and whether or not the vehicle is approaching from the outputs of these ultrasonic sensors. The vehicle approach detection unit 23 for detecting the alarm, the output of the vehicle approach detection unit 23 and the seat belt wearing presence / absence detection unit 16 determines whether or not to issue an alarm, and the alarm determination and alarm for issuing an alarm according to the determination result A generator 24 is provided.
[0018]
Right rear detecting the ultrasonic sensor 21 is provided on the right corner portion of the vehicle rear, left rear detecting ultrasonic sensor 22 is provided in the left corner of the rear portion of the vehicle. FIG. 3 shows the distance measurement ranges of the right rear detection ultrasonic sensor 21 and the left rear detection ultrasonic sensor 22. The right rear detection ultrasonic sensor 21 and the left rear detection ultrasonic sensor 22 reflect the distance to an obstacle such as a vehicle included in the distance measurement range in FIG. 3 from the transmission of the ultrasonic wave and return to the obstacle. And a distance signal corresponding to the distance to the obstacle is output to the vehicle approach detection unit 23.
[0019]
The vehicle approach detection unit 23 determines whether or not an obstacle is approaching based on temporal changes in the distance signals output from the right rear detection ultrasonic sensor 21 and the left rear detection ultrasonic sensor 22, and according to the presence or absence of the approach. The signal is output to the alarm judgment and alarm generation unit 24.
[0020]
The seat belt wearing presence / absence detecting unit 16 detects whether or not the seat belt is worn, and outputs a signal corresponding to whether or not the seat belt is worn to the alarm determination and warning generating unit 24.
[0021]
The warning determination and warning generation unit 24 outputs from the vehicle approach detection unit 23 when detecting that the seat belt has changed from the wearing state to the non-wearing state based on the signal output from the seat belt wearing presence / absence detecting unit 16. The detected signal is detected. Further, the alarm determination and alarm generation unit 24 determines whether the seat in which the seat belt is changed from the mounted state to the non-mounted state is a driver seat, a passenger seat, a rear right seat, a rear center seat, or a rear left seat. . The alarm judgment and alarm generation unit 24 includes a vehicle approaching from the rear, a position where the vehicle approaches (left and right), and a position of the seat where the seat belt is changed from the mounted state to the non-mounted state (left and right). ) Alerts in common. When the seat in which the seat belt is changed from the attached state to the non-attached state is the rear center seat, an alarm is issued regardless of whether the vehicle approaches the left or right.
[0022]
As described above, according to the present embodiment, the alarm determination and alarm generation unit 24 has a vehicle approaching from the rear, and the position (left and right) at which the vehicle approaches and the seat belt from the mounted state. Since the alarm is issued when the position (left and right) of the seat in the non-mounted state is common, the danger can be recognized before the occupant opens the vehicle door.
[0023]
The vehicle alarm unit 20 of the present embodiment can also be applied when the vehicle approaches from the left and right rear at the same time, such as when the vehicle is parked. It can also be applied when there are multiple.
[0024]
In this embodiment, the seat belt wearing presence / absence detecting unit 16 and the vehicle warning unit 20 connected to the electric retractor 100 are used as the vehicle warning device. However, the vehicle warning device detects whether or not the seat belt is worn. It is only necessary to include the unit 16 and the vehicle alarm unit 20, and it may not be connected to the electric retractor 100.
[0025]
