発明の詳細な説明Detailed Description of the Invention

本発明は、自動車に搭載されているテレビ機能付のカーナビゲーション装置(以下テレビ、ナビ装置という)のテレビ放送、ビデオ再生、DVD再生等の表示及びナビゲーションの操作(以下テレビの表示及びナビ操作という)が自動車の走行中はできないように機能制限されているテレビ、ナビ装置の機能制限を解除するための制御装置に関するものである。The present invention provides display and navigation operations (hereinafter referred to as TV display and navigation operations) of a TV navigation, video playback, DVD playback, and the like of a car navigation device with a TV function (hereinafter referred to as a TV and a navigation device) installed in an automobile. ) Relates to a control device for canceling the function restriction of the TV and the navigation device whose functions are restricted so that they cannot be performed while the vehicle is running.

技術背景Technical background

現在、自動車の走行中は安全確保のため、運転者は設置されているテレビ、ナビ装置のテレビ放送、ビデオ再生、DVD再生等の表示を注視してはならないとされている。くわえて走行中に運転者はナビゲーションの操作を行ってはならないとされている。このような行為は道路交通法によって禁止されている。これに応じて自動車メーカーが装着するテレビ、ナビ装置では自動車が停止中にはテレビの表示及びナビ操作ができるが、走行中にはテレビの表示及びナビ操作ができないように設計されている。Currently, in order to ensure safety while driving a car, the driver should not watch the display of the installed TV, TV broadcast of the navigation device, video playback, DVD playback, etc. In addition, it is said that the driver must not operate the navigation while driving. Such acts are prohibited by the Road Traffic Act. Accordingly, televisions and navigation devices installed by automobile manufacturers are designed so that television display and navigation operations can be performed while the vehicle is stopped, but television display and navigation operations cannot be performed while traveling.

近年のテレビ、ナビ装置では、エンジンコンピューター等から出力される車速パルス信号と、パーキングブレーキの状態を検出する信号と、GPS(Global Positioning System)による位置情報等の複数の入力信号のうちの1つ、または2つ以上の入力信号を組みあせて、自動車が走行中なのか停止中なのかを判別し、自動車の走行中は同乗者を含む全て人がテレビの表示及びナビ操作を出来ないように制限し、停止中はテレビの表示及びナビ操作が出来るように制御されている。In recent televisions and navigation devices, one of a plurality of input signals such as a vehicle speed pulse signal output from an engine computer, a signal for detecting a parking brake state, and position information by GPS (Global Positioning System). Or, combine two or more input signals to determine whether the car is running or stopped, so that everyone including passengers can not display and navigate the TV while the car is running It is controlled so that it can be displayed and navigated while it is stopped.

自動車が走行中であっても、同乗者がテレビ放送等の視聴または、ナビゲーションの操作をするのであればまったく危険ではない。しかし、走行中にテレビの表示及びナビ操作を出来ないように制限されたテレビ、ナビ装置の場合はたとえ助手席の同乗者であってもテレビ放送等の視聴または、ナビゲーションの操作をすることはできない。Even if the car is running, it is not at all dangerous if the passenger is watching TV broadcasting or operating navigation. However, in the case of a television or navigation device that is restricted so that it cannot be displayed and navigated while driving, even if it is a passenger in the passenger seat, it is not possible to view television broadcasts or perform navigation operations. Can not.

例えば、同乗者であってもナビゲーションの操作をするためには、わざわざ自動車を停止させる必要あり、非常に不便であった。また高速道路を走行中などは自動車を停止できる場所も限られており、さらに不便であった。For example, even in the case of a passenger, in order to perform navigation operations, it is necessary to stop the vehicle and it is very inconvenient. In addition, there are limited places where cars can be stopped while driving on highways, which is further inconvenient.

本発明は、上記の課題を解決するもので、走行中はテレビの表示及びナビ操作が制限されたテレビ、ナビ装置であっても、助手席に同乗者がいる場合に限って走行中でもテレビの表示及びナビ操作を可能にするための制御装置である。The present invention solves the above-described problems. Even if a television or a navigation device is restricted in the display and navigation operation of the television while traveling, the television can only be used while traveling in a passenger seat only. It is a control device for enabling display and navigation operations.

近年の自動車の助手席には、人物が座ったことを検出する着座検出スイッチと助手席の同乗者がシートベルトを装着したか否かを検出するスイッチが設置されている。これは道路交通法の改正により、同乗者もシートベルトを装着しなければならないということから、助手席に同乗者がいる場合には、シートベルト非装着の警告を促すインジケーターを点灯又は点滅させるために、自動車メーカーが設置している。2. Description of the Related Art A seat detection switch for detecting that a person is seated and a switch for detecting whether or not a passenger in the passenger seat is wearing a seat belt are installed in a passenger seat of a recent automobile. This is because the passenger is required to wear a seat belt due to the revision of the Road Traffic Law, so if there is a passenger in the passenger seat, an indicator prompting the warning of not wearing the seat belt will be lit or flashing. In addition, it is installed by automakers.

本発明では、この助手席の着座スイッチと助手席のシートベルト装着検出スイッチを使用して、助手席に同乗者が座り、シートベルトを装着した場合に限り、自動車の走行中にテレビの表示及びナビ操作ができないように機能制限をするために使用されている、停止中か走行中かを検出する1つ以上の入力信号とその入力信号が入力されるべきテレビ、ナビ装置との間に設けられた切替回路とこの切替回路を制御する制御回路を備えた車載用テレビ、ナビ制御装置を特徴とする。In the present invention, only when the passenger sits in the passenger seat and wears the seat belt using the passenger seat seating switch and the passenger seat seat belt wearing detection switch, the television display and Provided between one or more input signals that are used to limit functions so that navigation operations cannot be performed and detect whether the vehicle is stopped or running, and a television or navigation device to which the input signals are to be input And an in-vehicle television and a navigation control device provided with the switching circuit and the control circuit for controlling the switching circuit.

本発明の制御装置では、運転者一人の場合は自動車メーカーの設計どおり、走行中にはテレビの表示及びナビ操作ができない状態となり、安全性を確保できる。
また助手席に同乗者がいる場合はこの機能制限を解除できるので、運転者の安全性と同乗者の利便性を両立することができることからこの発明が有効である。
In the control device according to the present invention, in the case of one driver, the display of the television and the navigation operation cannot be performed during traveling as designed by the automobile manufacturer, and safety can be ensured.
In addition, when there is a passenger in the passenger seat, this function restriction can be released, so that the safety of the driver and the convenience of the passenger can be compatible, and the present invention is effective.

本発明の一実施形態を図面にしたがって説明する。
図2は本発明の制御装置を使用した代表的な接続示し、図1は純正テレビ、ナビ装置の代表的な走行中か停止中かを判別するための入力を示した図である。
An embodiment of the present invention will be described with reference to the drawings.
FIG. 2 shows a typical connection using the control device of the present invention, and FIG. 1 is a diagram showing an input for determining whether the genuine television or the navigation device is representatively running or stopped.

図1に示す107テレビ、ナビ装置に接続された101GPSアンテナはGPS(Global Positioning System)によってリアルタイムに車輌の位置を検出できるため、この信号をもとに車輌の位置検出や走行状態を107テレビ、ナビ装置が認識できる。The 101 GPS antenna connected to the 107 TV shown in FIG. 1 and the navigation device can detect the position of the vehicle in real time by GPS (Global Positioning System). The navigation device can be recognized.

また102エンジンコンピューターからは自動車が走行中は走行速度によって決まったパルス信号がカーテレビ装置に入力されている。当然このパルス信号は自動車が停止中は出力されない。In addition, a pulse signal determined by the traveling speed is input from the 102 engine computer to the car TV device while the vehicle is traveling. Naturally, this pulse signal is not output while the automobile is stopped.

また自動車が停止中に動作させる103パーキングブレーキの信号もテレビ、ナビ装置に入力されており、前記3つの入力信号のいずれもからでもテレビ、ナビ装置は自動車が走行中か停止中かを判別することができる。A 103 parking brake signal to be operated while the vehicle is stopped is also input to the TV and the navigation device, and the TV and navigation device determine whether the vehicle is running or stopped from any of the three input signals. be able to.

通常はこの3つの走行中か停止中かを判別できる信号のうち1つ以上を使用して107テレビ、ナビ装置は車輌が走行中か停止中かを判別し、走行中はテレビの表示及びナビ操作をできないように機能制限している。Normally, 107 TV and navigation devices use one or more of these three signals to determine whether the vehicle is running or stopped, and the navigation device discriminates whether the vehicle is running or stopped. Functions are restricted so that operations cannot be performed.

本発明の制御装置では前記3つの走行中か停止中かを判別できる信号と107テレビ、ナビ装置の間に装着し制御装置内の切替回路によって走行中であっても停止中と同じ信号を制御装置からテレビ、ナビ装置に入力することによって走行中であってもテレビの表示及びナビ操作ができるようになる。In the control device of the present invention, the above three signals that can be discriminated whether the vehicle is running or stopped and the same signal as when the vehicle is stopped are controlled by a switching circuit in the control device that is mounted between the 107 TV and the navigation device. By inputting data from the device to the television and the navigation device, the television can be displayed and the navigation operation can be performed even while traveling.

しかしこれだけでは、運転者が一人で走行中であってもテレビの表示及びナビ操作ができてしまうため、危険をともなう可能性があるため、本発明の制御装置には助手席に同乗者がいることを判別するために入力がもうけられている。However, with this alone, even if the driver is traveling alone, the television display and navigation operation can be performed, which may be dangerous. Therefore, the control device of the present invention has a passenger in the passenger seat. Input is made to determine this.

その1つが、助手席のシートに設置されている人物が座ったことを検出するための着座スイッチである。
2つ目が助手席に設置されているシートベルト装着を検出するためのシートベルトスイッチである。
One of them is a seating switch for detecting that a person installed on a passenger seat seats.
The second is a seat belt switch for detecting seat belt wearing installed in the passenger seat.

前記着座スイッチとシートベルトスイッチの信号は本発明の制御装置に入力し、助手席に同乗者が座っており、なおかつシートベルトを装着している場合にかぎり、本発明の制御装置よりテレビ、ナビ装置に擬似的な停止状態の信号を出力し、走行中であってもテレビの表示及びナビ操作ができるようになる。The seat switch and seat belt switch signals are input to the control device of the present invention, and only when the passenger is seated in the passenger seat and the seat belt is worn, the control device of the present invention allows the television, A pseudo stop signal is output to the device so that the television can be displayed and navigated even while traveling.

助手席に同乗者がいない、もしくは助手席の同乗者がシートベルトを装着していない場合はこの動作はなされないので、運転者一人の場合にいたっては走行中にテレビの表示及びナビ操作ができない。If there is no passenger in the passenger seat, or if the passenger in the passenger seat is not wearing a seat belt, this operation will not be performed. Can not.

図3は本発明の制御装置の動作条件をフォローチャートにより解説したものである。
本発明の制御装置及びテレビ、ナビ装置は運転者がキーをオンの状態もしくはエンジンをスタートしたした時に動作を開始する。(ステップSS1)
ステップSS1の状態だとテレビ、ナビ装置は通常の動作、すなわち走行中はテレビの表示及びナビ操作が出来ない状態である。
次に助手席に人物が着座したか否かを着座スイッチの入力により判別し、もし着座していなければ、テレビ、ナビ装置は通常の動作となり、走行中はテレビの表示及びナビ操作ができない状態となる。(ステップSS2)
FIG. 3 explains the operating conditions of the control device of the present invention with a follow chart.
The control device, the television, and the navigation device of the present invention start to operate when the driver turns on the key or starts the engine. (Step SS1)
In the state of step SS1, the television and the navigation device are in a normal operation, that is, the state in which the television display and the navigation operation cannot be performed during traveling.
Next, it is determined whether or not a person is seated in the passenger seat by inputting a seating switch, and if not seated, the TV and navigation device will operate normally, and the television display and navigation operations cannot be performed while driving. It becomes. (Step SS2)

ステップSS2で着座スイッチにより助手席に人が座ったことを検出した場合は助手席の同乗者がシートベルトを装着したか否かシートベルトスイッチの入力により判別し、シートベルトが非装着の場合はステップSS2の判別に戻り、シートベルトの装着を検出できた場合は、ステップSS4になる。If it is detected in step SS2 that a person has been seated in the passenger seat by the seat switch, it is determined whether the passenger in the passenger seat has worn the seat belt by inputting the seat belt switch, and if the seat belt is not worn, Returning to the determination in step SS2, if it is detected that the seat belt is worn, the process proceeds to step SS4.

ステップSS4では助手席に同乗者が座っており、なおかつシートベルトを装着していることが検出できた状態なので、本発明の制御装置からテレビナビ装置に対して、自動車が走行中であっても停止中である擬似的な信号を出力するので、テレビの表示及びナビ操作ができる状態となる。In step SS4, since it is detected that a passenger is sitting in the passenger seat and the seat belt is worn, even if the vehicle is running from the control device of the present invention to the TV navigation device. Since a pseudo signal that is being stopped is output, the television can be displayed and navigated.

この様に、本発明の車載用テレビ、ナビ制御装置では、助手席に同乗者が座っており、なおかつシートベルトを装着している場合のみ、自動車が走行中であってもテレビの表示及びナビ操作ができる状態となる。Thus, in the in-vehicle TV and navigation control device of the present invention, only when the passenger is sitting in the passenger seat and wearing the seat belt, the display and navigation of the TV are possible even when the vehicle is running. The operation is ready.
