- Embodiments of the present invention will be described below with reference to FIGS. 1 to 5.
- the members and arrangements described below do not limit the present invention and can be variously modified within the scope of the gist of the present invention.
- An occupant protection control device (hereinafter referred to as “this device”) according to an embodiment of the present invention includes a control unit (indicated as “CPU” in FIG. 1) 1 and an interface circuit (indicated as “ASIC” in FIG. 1).
- the occupant protection device for example, a side airbag device (not shown) or the like is configured to be capable of driving control (ignition control) of a plurality of squibs 5-1 to 5-n.
- the control unit 1 has a storage element (not shown) such as a RAM or a ROM centered on a microcomputer (not shown) having a known and well-known configuration, for example. In addition, a drive control process of the apparatus described later is executed.
- the interface circuit 2 includes a squib fault diagnosis circuit and a constant current circuit for the driver's seat first and second squibs 3a and 3b of the driver's seat air bag device 3 to be described later, and an energization circuit for squib ignition. In the embodiment of the present invention, an application specific integrated circuit (ASIC) is used.
- this apparatus is provided with a backup power supply circuit, a warning lamp drive circuit, and the like. Are identical.
- the driver seat airbag device 3 and the passenger seat airbag device 4 both have a two-stage squib configuration as ignition means. That is, the driver's seat airbag device 3 includes the driver's seat first and second squibs 3a and 3b, and the passenger's seat airbag device 4 includes the passenger seat's first and second squibs 4a and 4b. Each has a configuration.
- FIG. 2 shows a flowchart of a drive control process executed by the control unit 1, and the contents thereof will be described with reference to FIG. In the following description, it will be described using the timing chart showing the ignition timing of the two-stage squib in FIGS. 3 to 5 as necessary.
- the horizontal axis represents the passage of time
- the vertical axis represents the presence or absence of ignition.
- step S100 in FIG. 2 an expansion determination algorithm is executed (see step S100 in FIG. 2). That is, a determination process is performed as to whether or not the driver airbag device 3, the passenger airbag device 4, and other passenger protection devices (not shown) should be deployed and activated.
- Such processing is basically the same as conventional processing, and detailed description thereof will be omitted.
- step S200 in FIG. 2 it is determined whether or not it is necessary to deploy the front airbag by executing the above-described deployment determination algorithm, that is, specifically, the driver airbag device 3 and the passenger airbag device 4. Is determined (see step S200 in FIG. 2). If it is determined that expansion is necessary (YES), step S202 is described below. On the other hand, if it is determined that it is not determined that expansion is necessary (NO), the execution of the expansion determination algorithm is repeated again.
- step S200 it is determined whether or not the determination that the driver's seat airbag device 3 needs to be deployed is a determination that so-called time difference deployment is necessary.
- the time difference deployment is an airbag deployment method in which the first-stage squib is ignited and then the second-stage squib is ignited after a predetermined time has elapsed. This is what has been done conventionally.
- step S202 When it is determined in step S202 that the time difference is not developed (in the case of NO), the first and second squibs are simultaneously ignited (see step S300 in FIG. 2). That is, the driver seat first squib 3a and the driver seat second squib 3b are simultaneously ignited, and the driver seat airbag device 3 is deployed.
- step S202 whether or not the first-stage squib is diagnosed as a failure state, that is, the driver's seat is determined by a separate squib failure diagnosis process. It is determined whether or not a diagnosis result indicating that the first squib 3a for use is in a failure state is obtained (see step S204 in FIG. 2).
- the squib fault diagnosis itself is based on a conventional method, and a detailed description thereof is omitted.
- the disconnection state depends on whether or not the voltage at both ends of the squib is a predetermined voltage. This is due to determining whether or not.
- Such a squib fault diagnosis process is executed repeatedly in the control unit 1 separately from the series of processes shown in FIG.
- the diagnosis result of whether or not the squib is in a failure state is stored in a predetermined storage area of the control unit 1, for example, a predetermined diagnosis flag is set to “1” or “0” according to the diagnosis result. It is updated according to the execution result of the next failure diagnosis process. Therefore, the process of step S204 does not newly diagnose whether or not the first-stage squib is faulty, but is the result of the most recent squib fault diagnosis process, that is, specifically as described above. By reading a diagnostic flag and determining its value, it is determined whether or not the first-stage squib has been diagnosed as a failure state.
- step S204 if it is determined that the first squib 3a for the driver's seat has been diagnosed as a failure state (in the case of YES), the process proceeds to step S400 described later, while the first for the driver's seat is When it is determined that the squib 3a is not diagnosed as being in a failure state (in the case of NO), the first-stage deployment process, that is, the first squib 3a for the driver's seat is ignited, and the driver's seat airbag The device 3 is brought into the first stage of unfolding (step S700 in FIG. 2).
- step S900 a predetermined time elapses by time processing (see step S800 in FIG. 2), and then the second stage expansion processing is performed (see step S900 in FIG. 2). That is, in step S900, the driver's seat second squib 3b is ignited and the driver's seat airbag device 3 is fully deployed.
- step S700 to step S900 described above is the same as conventional processing.
- the ignition timing of the driver's seat first squib 3a and the driver's seat second squib 3b is respectively As shown in FIG. 3, first, the first squib 3a for the driver's seat is ignited (see FIG. 3A), and then the second squib 3b for the driver's seat is ignited after a predetermined time has elapsed. (See FIG. 3B).
- step S400 the driver seat first squib 3a is replaced with the driver seat first squib 3a based on the determination result in step S204 that the driver seat first squib 3a is diagnosed as being in a failure state.
- the second stage unfolding process in which the second squib 3b is originally ignited at the timing when the first squib 3a for the driver's seat is ignited is executed (see FIG. 4B).
- time difference processing is executed (see step S500 in FIG. 2).
- this time difference process is basically the same as the time difference process in the previous step S800, and therefore the description thereof is omitted here.
- a first stage expansion process is performed in which the driver's seat first squib 3a is ignited (see FIG. 4A).
- the determination result is that the first squib 3a for the driver's seat is diagnosed as a failure state
- the first driver's seat squib 3a is again determined in this step S600.
- the reason why the squib 3a is ignited is that there is a possibility that the squib 3a will be successfully ignited a second time.
- the second driver squib 3b is originally ignited at the timing when the driver squib 3a is ignited as described below. It is based on such a viewpoint. That is, in the airbag apparatus having the conventional two-stage squib, as described above, even if the first squib is in a failure state at the ignition timing of the first squib, The stage squib is usually ignited at a predetermined timing, that is, at a predetermined timing after a lapse of a predetermined time from the ignition timing of the first stage squib.
- the timing for originally igniting the first squib 3a for the driver's seat instead of the first squib 3a for the driver's seat is used.
- the second squib 3b for the driver's seat is ignited, and then, at the timing when the second squib 3b for the driver's seat is originally ignited, the ignition for the first squib 3a for the driver's seat is attempted again.
- the first squib 3a for the driver's seat and the second squib 3b for the driver's seat may be ignited simultaneously.
- step S204 the driver's seat second squib 3b is ignited at the original timing of igniting the driver's seat first squib 3a (see FIG. 5B), and the driver's seat first squib 3b is ignited. It is also preferable to attempt ignition by outputting an ignition signal to 3a (see FIG. 5A).
- the airbag apparatus has been described as an example.
- the present invention is not limited to this, and other passenger protection such as a belt tensioner having two-stage ignition means is possible.
- the present invention can also be applied to device drive control. That is, for example, in the case of a belt tensioner having two-stage ignition means, the first-stage ignition means is diagnosed after the first-stage ignition means is diagnosed as a failure state, as in the embodiment of the present invention. In this drive timing (ignition timing), the second stage ignition means is driven (ignited) instead of the first stage ignition means, and then the original drive timing (ignition timing) of the second stage ignition means is reached. It is preferable to drive (ignite) the first stage ignition means.

Abstract
Description
また、特許文献2には、衝突の際の衝撃に応じて電気的検出信号を出力する第1のセンサと、機械的な構成を有して衝撃の有無によって開閉成する第2のセンサとを設け、実際の衝突が無いにも関わらず回路の誤動作等によって第1のセンサによって衝突が検出されたと等価な状態となっても、第2のセンサによって衝撃が検出されていない場合には、第1及び第2のスクイブが点火されない構成とし、エアバッグが誤って展開されることを防止したものが提案されている。
そのような観点から、2段構成のスクイブにおいては、一つの可能性として、例えば、1段目のスクイブが何らかの原因により点火できず、2段目のスクイブのみが点火可能となる故障状態が考えられるが、かかる場合にあっても、乗員への衝撃を最大限抑圧可能とする乗員保護装置が所望される。
前記乗員保護装置の第1の点火手段の点火の際に、前記第1の点火手段が故障状態にある場合に、前記第1の点火手段に代えて、第2の点火手段を、前記第1の点火手段の点火タイミングに点火し、前記第2の点火手段の本来の点火タイミングに、前記第1の点火手段を点火するよう構成されてなる乗員保護制御装置の駆動制御方法が提供される。
本発明の第2の形態によれば、2つの点火手段を有する2段点火式の乗員保護装置の駆動を制御する乗員保護制御装置であって、車両衝突の有無の判定結果に基づいて前記2つの点火手段の点火制御が可能に構成されてなる制御部と、前記制御部においてなされた前記2つの点火手段の点火の要否に応じて、前記2つの点火手段の点火を可能とするよう構成されてなるインターフェイス回路とを具備してなる乗員保護制御装置において、
前記制御部は、前記第1の点火手段の故障診断を行い、前記第1の点火手段が故障と診断された後に、前記点火手段の点火を行う場合、前記第1の点火手段に代えて前記第2の点火手段を、前記第1の点火手段の点火タイミングに点火せしめ、前記第2の点火手段の本来の点火タイミングに、前記第1の点火手段を点火せしめるようよう構成されてなるものが提供される。

なお、以下に説明する部材、配置等は本発明を限定するものではなく、本発明の趣旨の範囲内で種々改変することができるものである。
最初に、本発明の実施の形態における乗員保護制御装置(図1においては「ECU」と表記)の構成について、図1を参照しつつ説明する。
本発明の実施の形態における乗員保護制御装置(以下「本装置」と称する)は、制御部(図1においては「CPU」と表記)1と、インターフェース回路(図1においては「ASIC」と表記)2とを具備してなり、自動四輪車両における乗員保護装置としての運転席用エアバッグ装置3及び助手席用エアバッグ装置4の駆動制御を可能とすると共に、詳細は省略するが他の乗員保護装置、例えば、側面エアバッグ装置(図示せず)などに設けられた複数のスクイブ5-1~5-nの駆動制御(点火制御)を可能に構成されたものとなっている。
インターフェイス回路2は、後述する運転席用エアバッグ装置3の運転席用第1及び第2のスクイブ3a,3b等のスクイブの故障診断回路や定電流回路の他、スクイブの点火のための通電回路などを有してなるもので、本発明の実施の形態においては、ASIC(Application Specific Integrated Circuit)が用いられたものとなっている。
なお、本装置は、図1において図示が省略されているが、バックアップ電源回路、ワーニングランプ駆動回路などが設けられたものとなっており、本装置のこのような構成自体は、従来装置と基本的に同一である。
すなわち、運転席用エアバッグ装置3は、運転席用第1及び第2のスクイブ3a,3bを、助手席用エアバッグ装置4は、助手席用第1及び第2のスクイブ4a,4bを、それぞれ具備した構成となっている。
ステップS202においては、運転席用エアバッグ装置3の展開を必要とする判断が、いわゆる時間差展開が必要であるとする判断であったか否かが判定されることとなる。
ここで、時間差展開は、図3に示されたように、1段目のスクイブを点火させた後、所定時間経過後に2段目のスクイブを点火させるエアバッグ展開方法であり、かかる展開方法は、従来から行われているものである。
ここで、スクイブの故障診断自体は、従来から行われている方法によるもので、その詳細な説明は省略するが、例えば、スクイブの両端の電圧が所定の電圧であるか否かによって、断線状態であるか否かを判定するなどによるものである。かかるスクイブ故障診断処理は、制御部1において、図2に示された一連の処理とは別個に、周的的に繰り返し実行されるようになっているものである。通常、スクイブが故障状態にあるか否かの診断結果は、例えば、所定の診断用フラグが診断結果に応じて”1”又は”0”に設定され、制御部1の所定の記憶領域に記憶され、次回の故障診断処理の実行結果によって更新されるようになっている。したがって、ステップS204の処理は、1段目のスクイブが故障か否かを新たに診断するのではなく、直近に行われたスクイブ故障診断処理の結果、すなわち、具体的には、上述のような診断用フラグを読み込み、その値を判定することによって、1段目のスクイブが故障状態と診断されているか否かを判定するものである。
すなわち、ステップS900においては、運転席用第2のスクイブ3bが点火され、運転席用エアバッグ装置3が全展開状態とされることとなる。
かかる時間差処理の後、運転席用第1のスクイブ3aが、点火される1段目展開処理が実行されることとなる(図4(A)参照)。ここで、先のステップS204において、運転席用第1のスクイブ3aが故障状態と診断されているとの判定結果であったにも関わらず、このステップS600において、再度、運転席用第1のスクイブ3aの点火を行うのは、二度目に点火が成功する可能性もあることを考慮したためである。
上述したように、運転席用第1のスクイブ3aに代えて、運転席用第2のスクイブ3bを、本来、運転席用第1のスクイブ3aが点火されるタイミングで点火するのは、次述するような観点に基づくものである。
すなわち、従来の2段式スクイブを有してなるエアバック装置においては、先に述べたように、1段目のスクイブの点火タイミングに、1段目のスクイブが故障状態にあっても、2段目のスクイブは、あくまでも、予め定められたタイミングに、すなわち、1段目のスクイブの点火タイミングから所定時間経過後の所定のタイミングに点火されるのが通常であった。しかし、乗員保護の確実性のさらなる向上という観点からは、1段目のスクイブの点火タイミングにおいて、1段目のスクイブの点火に応じた本来の規模のエアバックの展開が確保されないまでも、若干の規模でもエアバックが展開されることで、乗員の体がハンドルに当たるタイミングに、展開されたエアバックによる乗員のハンドルへの衝突による衝撃が多少でも緩和できることとなり、乗員保護のさらなる確実性の向上となると考えられるからである。
