車速は、車速検出器によって検出されるが、車速検出器による車速の検出は、キーオフ操作に応じて生成されるキーオフ信号を基に停止される。そのため、車両が走行している最中にキーオフ操作を行うと、車速検出器による車速の検出が停止し、車速制限装置による車速の制限が無効化されてしまう可能性がある。 The vehicle speed is detected by the vehicle speed detector, but the vehicle speed detection by the vehicle speed detector is stopped based on the key-off signal generated in response to the key-off operation. Therefore, if the key-off operation is performed while the vehicle is running, the detection of the vehicle speed by the vehicle speed detector may be stopped, and the vehicle speed limitation by the vehicle speed limiting device may be invalidated.

In addition, an engine output reducing device for reducing the output of the engine mounted on the own vehicle, a key-off signal generating device for generating a key-off signal for stopping the detection of the vehicle speed by the vehicle speed detector in response to a key-off operation, and the like. A vehicle speed limiting device comprising the above, which determines whether or not the own vehicle is running based on the vehicle speed detected by the vehicle speed detector, and when the own vehicle is running, the key-off signal generation device. Provided is a vehicle speed limiting device further including a key-off signal generation prohibiting device for prohibiting the generation of the key-off signal.

It is desirable to further determine whether or not the key-off signal is generated, and if the own vehicle is not located on the highway even when the own vehicle is traveling, it is desirable to allow the key-off signal generator to generate the key-off signal.

以下、実施の形態を添付図面に順って説明する。 Hereinafter, embodiments will be described in order of the accompanying drawings.

図１に示す様に、車速制限装置１００は、自車両１０１の車速を制限するものであって、車速検出器１０２と、機関出力低下装置１０３と、キーオフ信号生成装置１０４と、キーオフ信号生成禁止装置１０５と、を備える。 As shown in FIG. 1, the vehicle speed limiting device 100 limits the vehicle speed of the own vehicle 101, and the vehicle speed detector 102, the engine output lowering device 103, the key-off signal generator 104, and the key-off signal generation prohibition are prohibited. The device 105 is provided.

車速検出器１０２は、車速を検出するものである。車速検出器１０２は、例えば、車軸の回転数を基に車速を検出するものであっても、後述の車位置測定装置１０６で測定された車位置を基に車速を検出するものであっても良い。 The vehicle speed detector 102 detects the vehicle speed. For example, the vehicle speed detector 102 detects the vehicle speed based on the rotation speed of the axle, or detects the vehicle speed based on the vehicle position measured by the vehicle position measuring device 106 described later. good.

機関出力低下装置１０３は、車速検出器１０２で検出された車速が制限車速以上か否かを判定し、車速検出器１０２で検出された車速が制限車速以上の場合に、自車両１０１に搭載された機関１０７の出力を低下させるものである。 The engine output reduction device 103 determines whether or not the vehicle speed detected by the vehicle speed detector 102 is equal to or higher than the limit vehicle speed, and is mounted on the own vehicle 101 when the vehicle speed detected by the vehicle speed detector 102 is equal to or higher than the limited vehicle speed. It reduces the output of the engine 107.

機関１０７は、例えば、エンジンやモータである。機関１０７がエンジンである場合は、エンジンへの燃料の供給を減少させる事によって機関１０７の出力を低下させる。機関１０７がモータである場合は、モータへの電力の供給を減少させる事によって機関１０７の出力を低下させる。 The engine 107 is, for example, an engine or a motor. When the engine 107 is an engine, the output of the engine 107 is reduced by reducing the supply of fuel to the engine. When the engine 107 is a motor, the output of the engine 107 is reduced by reducing the supply of electric power to the motor.

キーオフ信号生成装置１０４は、キーオフ操作に応じて、車速検出器１０２による車速の検出を停止させるキーオフ信号を生成するものである。キーオフ操作は、例えば、イグニッションキーやイグニッションスイッチをオンからオフに切り換える操作である。 The key-off signal generation device 104 generates a key-off signal that stops the detection of the vehicle speed by the vehicle speed detector 102 in response to the key-off operation. The key-off operation is, for example, an operation of switching the ignition key or the ignition switch from on to off.

キーオフ信号が生成されると、車速検出器１０２による車速の検出が停止される他、機関１０７の主要な動作に関与しない又は関与が少ない種々の機器の動作も停止されるが、一般的に、自車両１０１が走行中の場合は、キーオフ信号が生成されても、機関１０７や機関１０７の主要な動作に関与する機器は直ぐに停止されない。 When the key-off signal is generated, the vehicle speed detection by the vehicle speed detector 102 is stopped, and the operation of various devices that are not involved in or have little involvement in the main operation of the engine 107 is also stopped. When the own vehicle 101 is traveling, even if the key-off signal is generated, the engine 107 and the devices involved in the main operation of the engine 107 are not immediately stopped.

自車両１０１が走行中に機関１０７や機関１０７の主要な動作に関与する機器が直ぐに停止されると、急減速に伴う重大な事故が発生する虞が有るので、少なくとも自車両１０１が安全に停車される迄は、キーオフ信号が生成されても、機関１０７や機関１０７の主要な動作に関与する機器は直ぐに停止されず、アクセル操作やブレーキ操作を行う事が出来る。 If the engine 107 and the devices involved in the main operation of the engine 107 are immediately stopped while the own vehicle 101 is running, a serious accident due to sudden deceleration may occur. Therefore, at least the own vehicle 101 is safely stopped. Until the key-off signal is generated, the engine 107 and the devices involved in the main operation of the engine 107 are not immediately stopped, and the accelerator operation and the brake operation can be performed.

従来の車速制限装置では、自車両１０１が走行中の意図的なキーオフ操作で車速検出器１０２による車速の検出を停止させる事によって、車速の制限を無効化する事が出来たが、制限車速以上での走行は大きな危険を伴うので、意図的なキーオフ操作で車速の制限を無効化する事が出来ない車速制限装置が望まれている。更に、種々の機器の動作が停止されると、他のシステムへの悪影響も懸念されるので、意図的なキーオフ操作で種々の機器の動作が停止される事も好ましくない。 In the conventional vehicle speed limiting device, the vehicle speed limitation can be invalidated by stopping the vehicle speed detection by the vehicle speed detector 102 by an intentional key-off operation while the own vehicle 101 is running, but the vehicle speed limit or higher Since traveling in a vehicle is very dangerous, a vehicle speed limiting device that cannot invalidate the vehicle speed limit by intentional key-off operation is desired. Further, when the operation of various devices is stopped, there is a concern that the operation of other devices may be adversely affected. Therefore, it is not preferable that the operations of various devices are stopped by an intentional key-off operation.

以上の事情に鑑み、車速制限装置１００は、意図的なキーオフ操作で車速の制限を無効化する事が出来ない様に、キーオフ信号生成禁止装置１０５を備える。キーオフ信号生成禁止装置１０５は、車速検出器１０２で検出された車速を基に自車両１０１が走行中か否かを判定し、自車両１０１が走行中の場合に、キーオフ信号生成装置１０４によるキーオフ信号の生成を禁止するものである。 In view of the above circumstances, the vehicle speed limiting device 100 includes a key-off signal generation prohibiting device 105 so that the vehicle speed limitation cannot be invalidated by an intentional key-off operation. The key-off signal generation prohibition device 105 determines whether or not the own vehicle 101 is running based on the vehicle speed detected by the vehicle speed detector 102, and when the own vehicle 101 is running, the key-off signal generation device 104 determines whether or not the own vehicle 101 is running. It prohibits the generation of signals.

機関出力低下装置１０３とキーオフ信号生成装置１０４とキーオフ信号生成禁止装置１０５は、一体であっても、別体であっても良い。図１では、電子制御装置１０８によって一体で実現される。 The engine output reduction device 103, the key-off signal generation device 104, and the key-off signal generation prohibition device 105 may be integrated or separate. In FIG. 1, it is integrally realized by the electronic control device 108.

車速制限装置１００では、キーオフ信号生成禁止装置１０５によって、自車両１０１が走行中の場合に、キーオフ信号生成装置１０４によるキーオフ信号の生成を禁止する事が出来るので、意図的なキーオフ操作で車速の制限を無効化する事が出来ず、適切な車速の制限を行う事が出来る。 In the vehicle speed limiting device 100, the key-off signal generation prohibiting device 105 can prohibit the generation of the key-off signal by the key-off signal generating device 104 when the own vehicle 101 is traveling. It is not possible to invalidate the restrictions, and it is possible to limit the vehicle speed appropriately.

所で、自車両１０１が走行中の場合でも、自車両１０１が一般道路上を走行中の場合は、車速が制限車速以上と成る事は稀である。即ち、悪意の有る者が意図的なキーオフ操作で車速の制限を無効化しようとするのは、自車両が高速道路上を走行中の場合が圧倒的多数である。 By the way, even when the own vehicle 101 is traveling, when the own vehicle 101 is traveling on a general road, the vehicle speed rarely exceeds the limit vehicle speed. That is, the overwhelming majority of malicious persons attempting to invalidate the vehicle speed limit by intentional key-off operation is when the vehicle is traveling on the highway.

従って、車速制限装置１００は、車位置測定装置１０６を更に備える。車位置測定装置１０６は、自車両の車位置を測定するものである。車位置測定装置１０６は、例えば、衛星測位システムの受信機である。車位置測定装置１０６は、車速検出器１０２と共に電子制御装置１０８に接続される。 Therefore, the vehicle speed limiting device 100 further includes a vehicle position measuring device 106. The vehicle position measuring device 106 measures the vehicle position of the own vehicle. The vehicle position measuring device 106 is, for example, a receiver of a satellite positioning system. The vehicle position measuring device 106 is connected to the electronic control device 108 together with the vehicle speed detector 102.

加えて、キーオフ信号生成禁止装置１０５は、車位置測定装置１０６で測定された車位置を基に自車両１０１が高速道路上に位置するか否かを更に判定し、自車両１０１が走行中の場合でも、自車両１０１が高速道路上に位置しない場合は、キーオフ信号生成装置１０４によるキーオフ信号の生成を許可する。 In addition, the key-off signal generation prohibition device 105 further determines whether or not the own vehicle 101 is located on the highway based on the vehicle position measured by the vehicle position measuring device 106, and the own vehicle 101 is traveling. Even in this case, if the own vehicle 101 is not located on the highway, the key-off signal generator 104 is allowed to generate the key-off signal.

従って、車速制限装置１００では、自車両１０１が一般道路上を走行中の場合は、キーオフ信号生成禁止装置１０５によって、キーオフ信号生成装置１０４によるキーオフ信号の生成を許可するので、緊急時にキーオフ操作を有効に機能させる事が出来る。 Therefore, in the vehicle speed limiting device 100, when the own vehicle 101 is traveling on the general road, the key-off signal generation prohibiting device 105 permits the key-off signal generation device 104 to generate the key-off signal, so that the key-off operation can be performed in an emergency. It can be made to function effectively.

但し、自車両１０１が高速道路上を走行中の場合でも、緊急時にキーオフ操作を有効に機能させる必要が有るので、キーオフ信号生成禁止装置１０５は、車速検出器１０２で検出された車速が制限車速以上と成る状態が所定時間内で連続するか否かを更に判定し、自車両１０１が走行中で、自車両１０１が高速道路上に位置する場合でも、車速検出器１０２で検出された車速が制限車速以上と成る状態が所定時間内で連続しない場合は、キーオフ信号生成装置１０４によるキーオフ信号の生成を許可する。 However, even when the own vehicle 101 is traveling on the highway, it is necessary to make the key-off operation function effectively in an emergency. Therefore, in the key-off signal generation prohibition device 105, the vehicle speed detected by the vehicle speed detector 102 is the limited vehicle speed. It is further determined whether or not the above-mentioned states are continuous within a predetermined time, and even when the own vehicle 101 is running and the own vehicle 101 is located on the highway, the vehicle speed detected by the vehicle speed detector 102 is If the state of exceeding the vehicle speed limit is not continuous within a predetermined time, the key-off signal generator 104 is allowed to generate the key-off signal.

車速検出器１０２で検出された車速が制限車速以上と成る状態が所定時間内で連続しない場合は、運転者が車速の制限を意図的に突破しようと考えている可能性が低く、緊急時に自車両１０１を安全に停止させようとしていると考えられるので、自車両１０１が高速道路上を走行中の場合でも、キーオフ操作を有効に機能させる。所定時間及び所定回数は、運転者が車速の制限を意図的に突破しようと考えているか否かを特定する事が出来る様に、統計的に決定される。 If the vehicle speed detected by the vehicle speed detector 102 does not continue to exceed the vehicle speed limit within a predetermined time, it is unlikely that the driver intentionally intends to break the vehicle speed limit, and in an emergency Since it is considered that the vehicle 101 is to be stopped safely, the key-off operation is effectively performed even when the own vehicle 101 is traveling on the highway. The predetermined time and the predetermined number of times are statistically determined so that it can be specified whether or not the driver intentionally intends to break the vehicle speed limit.

従って、車速制限装置１００では、キーオフ操作を有効に機能させる必要が有る場合に、キーオフ信号生成装置１０４によるキーオフ信号の生成を許可するので、利便性や安全性を低下させずに、意図的なキーオフ操作で車速の制限を無効化しようとする者の行動を阻止する事が出来る。 Therefore, in the vehicle speed limiting device 100, when it is necessary to make the key-off operation function effectively, the key-off signal generation device 104 is allowed to generate the key-off signal. It is possible to prevent the action of a person who tries to invalidate the vehicle speed limit by the key-off operation.

車速制限装置１００は、以下の手順で動作する。 The vehicle speed limiting device 100 operates according to the following procedure.

図２に示す様に、ステップＳ１０１では、機関出力低下装置１０３が車速検出器１０２で検出された車速が制限車速以上か否かを判定し、車速検出器１０２で検出された車速が制限車速以上の場合にステップＳ１０２に進み、車速検出器１０２で検出された車速が制限車速未満の場合にステップＳ１０３に進む。ステップＳ１０２では、機関出力低下装置１０３が機関１０７の出力を低下させる。ステップＳ１０３では、機関出力低下装置１０３による機関１０７の出力の低下を解除する。 As shown in FIG. 2, in step S101, the engine output reducing device 103 determines whether or not the vehicle speed detected by the vehicle speed detector 102 is equal to or higher than the limited vehicle speed, and the vehicle speed detected by the vehicle speed detector 102 is equal to or higher than the limited vehicle speed. In the case of, the process proceeds to step S102, and when the vehicle speed detected by the vehicle speed detector 102 is less than the limit vehicle speed, the process proceeds to step S103. In step S102, the engine output reducing device 103 reduces the output of the engine 107. In step S103, the reduction in the output of the engine 107 by the engine output reduction device 103 is released.

車速制限装置１００では、以上の動作によって車速が制限されるが、当該動作が実行されている間でも、キーオフ信号生成装置１０４が、キーオフ操作に応じて、車速検出器１０２による車速の検出を停止させるキーオフ信号を生成するので、意図的なキーオフ操作で車速検出器１０２による車速の検出を停止させると、ステップＳ１０１での判定が上手く行かず、車速の制限が無効化される。 In the vehicle speed limiting device 100, the vehicle speed is limited by the above operation, but the key-off signal generator 104 stops the vehicle speed detection by the vehicle speed detector 102 in response to the key-off operation even while the operation is being executed. Since the key-off signal is generated, if the vehicle speed detection by the vehicle speed detector 102 is stopped by an intentional key-off operation, the determination in step S101 does not go well and the vehicle speed limitation is invalidated.

従って、図３に示す様に、ステップＳ２０１では、キーオフ信号生成禁止装置１０５が車速検出器１０２で検出された車速を基に自車両１０１が走行中か否かを判定し、自車両１０１が走行中の場合にステップＳ２０２に進み、自車両１０１が停車中の場合にステップＳ２０３に進む。 Therefore, as shown in FIG. 3, in step S201, the key-off signal generation prohibition device 105 determines whether or not the own vehicle 101 is running based on the vehicle speed detected by the vehicle speed detector 102, and the own vehicle 101 is running. If it is inside, the process proceeds to step S202, and if the own vehicle 101 is stopped, the process proceeds to step S203.

ステップＳ２０２では、キーオフ信号生成禁止装置１０５が車位置測定装置１０６で測定された車位置を基に自車両１０１が高速道路上に位置するか否かを更に判定し、自車両１０１が高速道路上に位置する場合はステップＳ２０４に進み、自車両１０１が高速道路上に位置しない場合はステップＳ２０３に進む。 In step S202, the key-off signal generation prohibition device 105 further determines whether or not the own vehicle 101 is located on the highway based on the vehicle position measured by the vehicle position measuring device 106, and the own vehicle 101 is on the highway. If the vehicle 101 is not located on the highway, the process proceeds to step S204, and if the vehicle 101 is not located on the highway, the process proceeds to step S203.

ステップＳ２０３では、キーオフ信号生成禁止装置１０５がキーオフ信号生成装置１０４によるキーオフ信号の生成を許可する。 In step S203, the key-off signal generation prohibition device 105 permits the key-off signal generation device 104 to generate the key-off signal.

ステップＳ２０４では、キーオフ信号生成禁止装置１０５が車速検出器１０２で検出された車速が制限車速以上と成る状態が所定時間内で連続するか否かを更に判定し、車速検出器１０２で検出された車速が制限車速以上と成る状態が所定時間内で連続する場合はステップＳ２０５に進み、車速検出器１０２で検出された車速が制限車速以上と成る状態が所定時間内で連続しない場合はステップＳ２０３に進む。 In step S204, the key-off signal generation prohibition device 105 further determines whether or not the state in which the vehicle speed detected by the vehicle speed detector 102 is equal to or higher than the limit vehicle speed continues within a predetermined time, and is detected by the vehicle speed detector 102. If the state in which the vehicle speed exceeds the limit vehicle speed continues within the predetermined time, the process proceeds to step S205, and if the state in which the vehicle speed detected by the vehicle speed detector 102 exceeds the limit vehicle speed continues within the predetermined time, the process proceeds to step S203. move on.

ステップＳ２０５では、キーオフ信号生成禁止装置１０５がキーオフ信号生成装置１０４によるキーオフ信号の生成を禁止する。 In step S205, the key-off signal generation prohibition device 105 prohibits the key-off signal generation device 104 from generating the key-off signal.

尚、ステップＳ２０２及びＳ２０４の順序は問われず、またステップＳ２０２及びＳ２０４の一方又は両方は省略されても良い。 The order of steps S202 and S204 does not matter, and one or both of steps S202 and S204 may be omitted.

以上の動作によって、車両の走行中のキーオフ操作に基づくキーオフ信号の生成が無効化されるので、車速制限装置１００では、車両の走行中にキーオフ操作で車速の制限を無効化する事が出来ない。 By the above operation, the generation of the key-off signal based on the key-off operation while the vehicle is running is invalidated. Therefore, the vehicle speed limiting device 100 cannot invalidate the vehicle speed limit by the key-off operation while the vehicle is running. ..
