　なお、鍵操作部３ａは、車両の電源のオンとオフを切り換えることができればよく、特に限定されるものではない。例えば、鍵操作部３ａは、鍵を差し込んで電源を切り換えるもの、手でボタンを押して電源を切り換える、いわゆるプッシュスタート方式のものなどが挙げられる。 The key operation unit 3a is not particularly limited as long as it can switch the power of the vehicle on and off. For example, the key operation unit 3a includes a so-called push start type in which a key is inserted to switch the power supply and a button is manually pressed to switch the power supply.
　また、イグニッション電源７は、例えばエンジンを駆動した状態での使用が想定される電装品に給電するもので、鍵操作部３ａによりオンとオフが切り換えられる。 Further, the ignition power supply 7 supplies power to electrical components that are expected to be used while the engine is being driven, and is switched on and off by the key operation unit 3a.
　操作部３のパーキングブレーキ３ｂは、いわゆる摩擦ブレーキであり、運転者の操作により車輪を制動させるものである。 The parking brake 3b of the operation unit 3 is a so-called friction brake, which brakes the wheels by the operation of the driver.
　ヒューズ８は、イグニッション電源７から所定値以上の電流が流れた場合に光源制御装置６を保護するもので、所定値以上の電流により配線が溶断するように形成されている。 The fuse 8 protects the light source control device 6 when a current of a predetermined value or more flows from the ignition power supply 7, and is formed so that the wiring is blown by the current of the predetermined value or more.
　リレー回路９は、リレースイッチ１２と、リレーコイル１３と、リレー抵抗１４とを有する。 The relay circuit 9 has a relay switch 12, a relay coil 13, and a relay resistor 14.
　リレースイッチ１２は、イグニッション電源７と昼間走行灯５との間に配置され、可動接点１２ａと、固定接点１２ｂと、固定接点１２ｃとを有する。可動接点１２ａは、ヒューズ８を介してイグニッション電源７に接続されると共に、固定接点１２ｃに切り換え可能に固定接点１２ｂに接続されている。固定接点１２ｂは、非導通状態に配置されている。固定接点１２ｃは、昼間走行灯５に接続されている。すなわち、リレースイッチ１２は、可動接点１２ａが固定接点１２ｂに接続された場合には、イグニッション電源７が昼間走行灯５に接続されないオフ状態となる。また、リレースイッチ１２は、可動接点１２ａが固定接点１２ｃに接続された場合には、イグニッション電源７を昼間走行灯５に接続するオン状態となる。 The relay switch 12 is arranged between the ignition power source 7 and the daytime traveling light 5, and has a movable contact 12a, a fixed contact 12b, and a fixed contact 12c. The movable contact 12a is connected to the ignition power supply 7 via the fuse 8 and is also connected to the fixed contact 12b so as to be switchable to the fixed contact 12c. The fixed contact 12b is arranged in a non-conducting state. The fixed contact 12c is connected to the daytime traveling light 5. That is, when the movable contact 12a is connected to the fixed contact 12b, the relay switch 12 is in an off state in which the ignition power supply 7 is not connected to the daytime traveling light 5. Further, when the movable contact 12a is connected to the fixed contact 12c, the relay switch 12 is turned on to connect the ignition power supply 7 to the daytime traveling light 5.
　リレーコイル１３は、リレー回路１０およびヒューズ８を介してイグニッション電源７に直列に配置され、通電によりリレースイッチ１２をオン状態に切り換える、すなわち可動接点１２ａを固定接点１２ｃに接続するように切り換える。
　リレー抵抗１４は、リレーコイル１３に並列に配置され、リレーコイル１３への通電が停止した際にリレーコイル１３に持続的に流れる電流を消費するためのものである。 The relay coil 13 is arranged in series with the ignition power supply 7 via the relay circuit 10 and the fuse 8, and switches the relay switch 12 to the on state by energization, that is, switches so that the movable contact 12a is connected to the fixed contact 12c.
The relay resistor 14 is arranged in parallel with the relay coil 13 and is for consuming the current continuously flowing through the relay coil 13 when the energization of the relay coil 13 is stopped.
　リレー回路１０は、リレースイッチ１５と、リレーコイル１６と、リレー抵抗１７とを有する。 The relay circuit 10 has a relay switch 15, a relay coil 16, and a relay resistor 17.
　リレースイッチ１５は、イグニッション電源７とリレー回路９のリレーコイル１３との間に配置され、可動接点１５ａと、固定接点１５ｂと、固定接点１５ｃとを有する。可動接点１５ａは、ヒューズ８を介してイグニッション電源７に接続されると共に、固定接点１５ｃに切り換え可能に固定接点１５ｂに接続されている。固定接点１５ｂは、リレー回路９のリレーコイル１３に接続されている。固定接点１５ｃは、非導通状態に配置されている。すなわち、リレースイッチ１５は、可動接点１５ａが固定接点１５ｂに接続された場合には、イグニッション電源７をリレーコイル１３に接続するオン状態となる。また、リレースイッチ１５は、可動接点１５ａが固定接点１５ｃに接続された場合には、イグニッション電源７がリレーコイル１３に接続されないオフ状態となる。 The relay switch 15 is arranged between the ignition power supply 7 and the relay coil 13 of the relay circuit 9, and has a movable contact 15a, a fixed contact 15b, and a fixed contact 15c. The movable contact 15a is connected to the ignition power supply 7 via the fuse 8 and is also connected to the fixed contact 15b so as to be switchable to the fixed contact 15c. The fixed contact 15b is connected to the relay coil 13 of the relay circuit 9. The fixed contact 15c is arranged in a non-conducting state. That is, when the movable contact 15a is connected to the fixed contact 15b, the relay switch 15 is turned on to connect the ignition power supply 7 to the relay coil 13. Further, when the movable contact 15a is connected to the fixed contact 15c, the relay switch 15 is in an off state in which the ignition power supply 7 is not connected to the relay coil 13.
　リレーコイル１６は、イグニッション電源７と操作スイッチ１１との間に直列に配置され、通電によりリレースイッチ１５をオフ状態に切り換える、すなわち可動接点１５ａを固定接点１５ｃに接続するように切り換える。
　リレー抵抗１７は、リレーコイル１６に並列に配置され、リレーコイル１６への通電が停止した際にリレーコイル１６に持続的に流れる電流を消費するためのものである。 The relay coil 16 is arranged in series between the ignition power supply 7 and the operation switch 11, and switches the relay switch 15 to the off state by energization, that is, switches the movable contact 15a so as to be connected to the fixed contact 15c.
The relay resistor 17 is arranged in parallel with the relay coil 16 and is for consuming the current continuously flowing through the relay coil 16 when the energization of the relay coil 16 is stopped.
　なお、リレー回路９および１０は、同じ規格であり、例えばリレースイッチ１２とリレースイッチ１５はリレーコイル１３および１６への通電に対して同じ時間で切り換わる、すなわち同じ切り換わり速度を有する。 Note that the relay circuits 9 and 10 have the same standard, for example, the relay switch 12 and the relay switch 15 switch at the same time with respect to the energization of the relay coils 13 and 16, that is, they have the same switching speed.
　操作スイッチ１１は、パーキングブレーキ３ｂの操作に応じて切り換えられるもので、一方の接点がリレー回路１０のリレーコイル１６に接続され、他方の接点が接地されている。ここで、操作スイッチ１１は、パーキングブレーキ３ｂが作動されない場合はオフ状態であり、パーキングブレーキ３ｂが作動されることによりオフ状態からオン状態に切り換わるように設けられている。 The operation switch 11 is switched according to the operation of the parking brake 3b, one contact is connected to the relay coil 16 of the relay circuit 10, and the other contact is grounded. Here, the operation switch 11 is in the off state when the parking brake 3b is not operated, and is provided so as to switch from the off state to the on state when the parking brake 3b is operated.
　なお、光源制御装置６は、前照灯４の点灯に応じて昼間走行灯５を自動的に消灯するような回路を新たに配置することができる。例えば、光源制御装置６は、前照灯４の操作情報に基づいて昼間走行灯５の点灯を制御することができる。 Note that the light source control device 6 can newly arrange a circuit that automatically turns off the daytime traveling light 5 in response to the lighting of the headlight 4. For example, the light source control device 6 can control the lighting of the daytime traveling light 5 based on the operation information of the headlight 4.
　次に、本実施の形態の動作について説明する。 Next, the operation of this embodiment will be described.
　まず、図２に示すように、パーキングブレーキ３ｂが作動されると共に鍵操作部３ａが「ＬＯＣＫ」位置に操作されて車両が停車した状態となる。このパーキングブレーキ３ｂの作動により操作スイッチ１１がオン状態とされており、鍵操作部３ａが「ＬＯＣＫ」位置に位置することによりイグニッション電源７がオフ状態となる。このため、イグニッション電源７からリレーコイル１３および１６に通電されず、リレースイッチ１２の可動接点１２ａが固定接点１２ｂに接続されると共にリレースイッチ１５の可動接点１５ａが固定接点１５ｂに接続される。 First, as shown in FIG. 2, the parking brake 3b is activated and the key operation unit 3a is operated to the "LOCK" position, so that the vehicle is stopped. The operation switch 11 is turned on by the operation of the parking brake 3b, and the ignition power supply 7 is turned off when the key operation unit 3a is located at the "LOCK" position. Therefore, the relay coils 13 and 16 are not energized from the ignition power source 7, and the movable contact 12a of the relay switch 12 is connected to the fixed contact 12b, and the movable contact 15a of the relay switch 15 is connected to the fixed contact 15b.
　このとき、イグニッション電源７は切れた状態であり、リレースイッチ１２は可動接点１２ａが固定接点１２ｂに接続されたオフ状態であるため、昼間走行灯５は、給電されずに消灯した状態となる。 At this time, since the ignition power supply 7 is turned off and the relay switch 12 is in the off state in which the movable contact 12a is connected to the fixed contact 12b, the daytime traveling light 5 is turned off without supplying power.
　続いて、運転者が、パーキングブレーキ３ｂを作動させた状態で、鍵操作部３ａを「ＯＮ」位置に切り換えることによりイグニッション電源７が入れられる。 Subsequently, the driver turns on the ignition power supply 7 by switching the key operation unit 3a to the "ON" position while the parking brake 3b is activated.
　ここで、図３に示すように、リレー回路９を除いて、リレー回路１０のリレースイッチ１５に昼間走行灯５を直接接続した場合には、イグニッション電源７からリレーコイル１６に通電される一方、イグニッション電源７からリレースイッチ１５にも通電される。リレーコイル１６に通電されることにより、リレースイッチ１５は、可動接点１５ａが固定接点１５ｂから固定接点１５ｃに切り換えられてオフ状態となる。しかしながら、可動接点１５ａが固定接点１５ｃに切り換えられるまでの間、イグニッション電源７から昼間走行灯５に給電されるため、昼間走行灯５が瞬間的に点灯するおそれがある。特に、昼間走行灯５にＬＥＤライトを用いた場合には、点灯速度が速いため点灯時間が長くなるおそれがある。 Here, as shown in FIG. 3, when the daytime traveling light 5 is directly connected to the relay switch 15 of the relay circuit 10 except for the relay circuit 9, the ignition power supply 7 energizes the relay coil 16 while the ignition power supply 7 is energized. The ignition power supply 7 also energizes the relay switch 15. When the relay coil 16 is energized, the relay switch 15 is turned off by switching the movable contact 15a from the fixed contact 15b to the fixed contact 15c. However, since the ignition power source 7 supplies power to the daytime traveling light 5 until the movable contact 15a is switched to the fixed contact 15c, the daytime traveling light 5 may be turned on instantaneously. In particular, when an LED light is used as the daytime traveling light 5, the lighting speed may be high and the lighting time may be long.
　そこで、図２に示すように、リレー回路１０と昼間走行灯５との間にリレー回路９を配置する。これにより、鍵操作部３ａが「ＯＮ」位置に切り換えられると、イグニッション電源７からリレー回路１０のリレーコイル１６に通電される一方、リレー回路９のリレーコイル１３とリレースイッチ１２にも通電される。 Therefore, as shown in FIG. 2, the relay circuit 9 is arranged between the relay circuit 10 and the daytime running light 5. As a result, when the key operation unit 3a is switched to the "ON" position, the ignition power supply 7 energizes the relay coil 16 of the relay circuit 10, while the relay coil 13 and the relay switch 12 of the relay circuit 9 are also energized. ..
　このとき、リレースイッチ１２は、可動接点１２ａが固定接点１２ｂに接続されたオフ状態であるため、イグニッション電源７から昼間走行灯５に給電されず、昼間走行灯５は消灯した状態となる。そして、イグニッション電源７からリレーコイル１３への通電によりリレースイッチ１２がオン状態に切り換わる間に、イグニッション電源７からリレーコイル１６への通電によりリレースイッチ１５がオフ状態に切り換えられる。これにより、図４に示すように、リレーコイル１３への通電が遮断されるため、リレースイッチ１２がオフ状態で維持される。 At this time, since the movable contact 12a is in the off state in which the movable contact 12a is connected to the fixed contact 12b, the ignition power source 7 does not supply power to the daytime traveling light 5, and the daytime traveling light 5 is turned off. Then, while the relay switch 12 is switched to the on state by energizing the ignition power source 7 to the relay coil 13, the relay switch 15 is switched to the off state by energizing the relay coil 16 from the ignition power source 7. As a result, as shown in FIG. 4, the energization of the relay coil 13 is cut off, so that the relay switch 12 is maintained in the off state.
　すなわち、操作スイッチ１１がオン状態の場合には、イグニッション電源７からリレーコイル１６に通電されてリレースイッチ１５がオフ状態に切り換えられることにより、イグニッション電源７からリレーコイル１３への通電が遮断される。これにより、リレーコイル１３がオフ状態とされるため、イグニッション電源７から昼間走行灯５への給電が持続的に停止されることになる。
　このようにして、鍵操作部３ａを「ＯＮ」位置に切り換えた直後にイグニッション電源７と昼間走行灯５とが電気的に接続されることを抑制し、昼間走行灯５の点灯を確実に制御することができる。このとき、イグニッション電源７と昼間走行灯５の間に２つのリレー回路９および１０を配置した簡単な構成で、昼間走行灯５の点灯を確実に制御することができる。 That is, when the operation switch 11 is in the ON state, the ignition power source 7 is energized to the relay coil 16 and the relay switch 15 is switched to the OFF state, so that the energization from the ignition power source 7 to the relay coil 13 is cut off. .. As a result, the relay coil 13 is turned off, so that the power supply from the ignition power source 7 to the daytime traveling light 5 is continuously stopped.
In this way, immediately after the key operation unit 3a is switched to the "ON" position, the ignition power supply 7 and the daytime traveling light 5 are suppressed from being electrically connected, and the lighting of the daytime traveling light 5 is reliably controlled. can do. At this time, the lighting of the daytime traveling light 5 can be reliably controlled by a simple configuration in which the two relay circuits 9 and 10 are arranged between the ignition power source 7 and the daytime traveling light 5.
　続いて、図５に示すように、運転者が、鍵操作部３ａを「ＳＴＡＲＴ」位置に切り換えてエンジンを駆動し、パーキングブレーキ３ｂを解除して車両を発進させる。このパーキングブレーキ３ｂの解除により、操作スイッチ１１がオフ状態となる。 Subsequently, as shown in FIG. 5, the driver switches the key operation unit 3a to the "START" position to drive the engine, releases the parking brake 3b, and starts the vehicle. By releasing the parking brake 3b, the operation switch 11 is turned off.
　操作スイッチ１１がオフ状態になることにより、イグニッション電源７からリレーコイル１６への通電が遮断されて、リレースイッチ１５が可動接点１５ａを固定接点１５ｂに接続するオン状態に切り換えられる。これにより、リレースイッチ１５を介してイグニッション電源７からリレーコイル１３に通電されて、リレースイッチ１２が可動接点１２ａを固定接点１２ｃに接続するオン状態に切り換えられる。そして、オン状態に切り換えられたリレースイッチ１２を介してイグニッション電源７から昼間走行灯５に給電される。 When the operation switch 11 is turned off, the energization from the ignition power source 7 to the relay coil 16 is cut off, and the relay switch 15 is switched to the on state in which the movable contact 15a is connected to the fixed contact 15b. As a result, the ignition power source 7 energizes the relay coil 13 via the relay switch 15, and the relay switch 12 is switched to the on state in which the movable contact 12a is connected to the fixed contact 12c. Then, power is supplied from the ignition power source 7 to the daytime traveling light 5 via the relay switch 12 that has been switched to the on state.
　すなわち、操作スイッチ１１がオフ状態の場合には、イグニッション電源７からリレーコイル１６への通電が遮断され、オン状態のリレースイッチ１５を介してリレーコイル１３に通電される。これにより、オン状態に切り換えられたリレースイッチ１２を介してイグニッション電源７から昼間走行灯５に給電されて、昼間走行灯５が点灯されることになる。 That is, when the operation switch 11 is in the off state, the energization from the ignition power source 7 to the relay coil 16 is cut off, and the relay coil 13 is energized via the relay switch 15 in the on state. As a result, power is supplied from the ignition power source 7 to the daytime traveling light 5 via the relay switch 12 switched to the on state, and the daytime traveling light 5 is turned on.
　このように、イグニッション電源７と昼間走行灯５の間に２つのリレー回路９および１０を配置した簡単な構成で、昼間走行灯５を自動的に点灯させることができる。これにより、昼間走行灯５を確実に点灯させることができ、車両を安全に走行させることができる。
　また、リレー抵抗１７が、リレーコイル１６への通電が遮断された際に、リレーコイル１６に流れる電流を消費するため、リレースイッチ１５を速やかにオン状態に切り換えることができる。 In this way, the daytime traveling light 5 can be automatically turned on with a simple configuration in which the two relay circuits 9 and 10 are arranged between the ignition power source 7 and the daytime traveling light 5. As a result, the daytime traveling light 5 can be reliably turned on, and the vehicle can be safely traveled.
Further, since the relay resistor 17 consumes the current flowing through the relay coil 16 when the energization of the relay coil 16 is cut off, the relay switch 15 can be quickly switched to the on state.
　このようにして、車両は、昼間走行灯５を点灯させた状態で走行される。そして、車両が再び停車されて、パーキングブレーキ３ｂが作動されると、操作スイッチ１１がオン状態とされる。これにより、イグニッション電源７からリレーコイル１６に通電されて、リレースイッチ１５がオフ状態となり、リレーコイル１３への通電が遮断される。そして、リレースイッチ１２がオフ状態に切り換えられることにより、イグニッション電源７から昼間走行灯５への給電が停止されて、昼間走行灯５が消灯することになる。 In this way, the vehicle runs with the daytime running light 5 turned on. Then, when the vehicle is stopped again and the parking brake 3b is activated, the operation switch 11 is turned on. As a result, the ignition power source 7 energizes the relay coil 16, the relay switch 15 is turned off, and the energization of the relay coil 13 is cut off. Then, when the relay switch 12 is switched to the off state, the power supply from the ignition power source 7 to the daytime traveling light 5 is stopped, and the daytime traveling light 5 is turned off.
　このように、車両の停車に応じて昼間走行灯５を自動的に消灯させることができ、無用な点灯を抑制することができる。 In this way, the daytime running light 5 can be automatically turned off when the vehicle is stopped, and unnecessary lighting can be suppressed.
　本実施の形態によれば、操作スイッチ１１がオン状態の場合には、リレーコイル１６に通電されてリレースイッチ１５がオフ状態に切り換えられることにより、リレーコイル１３への通電が遮断されて、リレースイッチ１２がオフ状態とされることによりイグニッション電源７から昼間走行灯５への給電が停止される。これにより、鍵操作部３ａを操作してイグニッション電源７を入れた直後に、イグニッション電源７と昼間走行灯５とが電気的に接続されることを抑制し、昼間走行灯５の点灯を確実に制御することができる。 According to the present embodiment, when the operation switch 11 is in the on state, the relay coil 16 is energized and the relay switch 15 is switched to the off state, so that the energization to the relay coil 13 is cut off and the relay is relayed. When the switch 12 is turned off, the power supply from the ignition power source 7 to the daytime traveling light 5 is stopped. As a result, immediately after the ignition power source 7 is turned on by operating the key operation unit 3a, it is suppressed that the ignition power source 7 and the daytime traveling light 5 are electrically connected, and the daytime traveling light 5 is surely turned on. Can be controlled.
　なお、本実施の形態では、リレー回路９とリレー回路１０は、リレーコイル１３および１６への通電に対してリレースイッチ１２および１５が同じ時間で切り換わる、すなわち切り換わり速度が同じもので構成されたが、これに限られるものではない。
　例えば、リレー回路９は、リレー回路１０のリレースイッチ１５と比較して、リレースイッチ１２の切り換わり速度が小さくなるように設けることができる。これにより、鍵操作部３ａを操作してイグニッション電源７を入れた際に、リレースイッチ１５がオフ状態に切り換わる前にリレースイッチ１２がオン状態に切り換わることを抑制することができ、昼間走行灯５の点灯をより確実に抑制することができる。 In the present embodiment, the relay circuit 9 and the relay circuit 10 are configured such that the relay switches 12 and 15 are switched at the same time with respect to the energization of the relay coils 13 and 16, that is, the switching speed is the same. However, it is not limited to this.
For example, the relay circuit 9 can be provided so that the switching speed of the relay switch 12 is smaller than that of the relay switch 15 of the relay circuit 10. As a result, when the ignition power supply 7 is turned on by operating the key operation unit 3a, it is possible to prevent the relay switch 12 from switching to the on state before the relay switch 15 switches to the off state, and it is possible to prevent the relay switch 12 from switching to the on state during daytime driving. The lighting of the lamp 5 can be suppressed more reliably.
　また、本実施の形態では、リレー回路９および１０は、イグニッション電源７に接続されたが、車両の電源に接続されていればよく、イグニッション電源７に限られるものではない。
　また、本実施の形態では、操作スイッチ１１は、パーキングブレーキ３ｂの操作に応じて切り換えられたが、車両の操作に応じて切り換えることができればよく、パーキングブレーキ３ｂに限られるものではない。 Further, in the present embodiment, the relay circuits 9 and 10 are connected to the ignition power source 7, but the relay circuits 9 and 10 may be connected to the power source of the vehicle and are not limited to the ignition power source 7.
Further, in the present embodiment, the operation switch 11 is switched according to the operation of the parking brake 3b, but it is not limited to the parking brake 3b as long as it can be switched according to the operation of the vehicle.
　また、本実施の形態では、リレー回路９および１０は、昼間走行灯５に接続されたが、車両の光源に接続されていればよく、昼間走行灯５に限られるものではない。 Further, in the present embodiment, the relay circuits 9 and 10 are connected to the daytime traveling light 5, but the relay circuits 9 and 10 are not limited to the daytime traveling light 5 as long as they are connected to the light source of the vehicle.
