　ここで、操作部３の鍵操作部３ａは、車両の電源を入れてエンジンを駆動するためのもので、「ＬＯＣＫ（ロック）」位置、「ＡＣＣ（アクセサリー）」位置、「ＯＮ（オン）」位置および「ＳＴＡＲＴ（スタート）」位置に切り換え可能に形成されている。鍵操作部３ａが「ＬＯＣＫ」位置に切り換えられると、イグニッション電源７ａおよびアクセサリー電源７ｂを含む車両の電源類が切られると共にエンジンが停止される。鍵操作部３ａが「ＡＣＣ」位置に切り換えられると、アクセサリー電源７ｂが入れられる。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７ａが入れられる。鍵操作部３ａが「ＳＴＡＲＴ」位置に切り換えられると、エンジンが駆動される。 Here, the key operation unit 3a of the operation unit 3 is for turning on the power of the vehicle and driving the engine, and is in the "LOCK" position, the "ACC (accessory)" position, and the "ON" position. It is formed so that it can be switched between the position and the "START" position. When the key operation unit 3a is switched to the "LOCK" position, the power of the vehicle including the ignition power supply 7a and the accessory power supply 7b is turned off and the engine is stopped. When the key operation unit 3a is switched to the "ACC" position, the accessory power supply 7b is turned on. When the key operation unit 3a is switched to the "ON" position, the ignition power supply 7a is turned on. When the key operation unit 3a is switched to the "START" position, the engine is driven.
　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.
　イグニッション電源７ａ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。
　アクセサリー電源７ｂは、例えばイグニッション電源７ａに接続された電装品より給電量が小さい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。鍵操作部３ａの「ＡＣＣ（アクセサリー）」位置は、「ＬＯＣＫ（ロック）」位置に対して「ＯＮ（オン）」位置より手前に配置されており、アクセサリー電源７ｂは、鍵操作部３ａの操作によりイグニッション電源７ａより前にオン状態とされることになる。 The ignition power supply 7a 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.
The accessory power supply 7b, for example, supplies power to an electrical component having a smaller power supply amount than the electrical component connected to the ignition power supply 7a, and is switched on and off by the key operation unit 3a. The "ACC (accessory)" position of the key operation unit 3a is located in front of the "ON" position with respect to the "LOCK" position, and the accessory power supply 7b is used to operate the key operation unit 3a. Therefore, the ignition power supply 7a is turned on before the ignition power supply 7a.
　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８ａは、イグニッション電源７ａ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。
　ヒューズ８ｂは、アクセサリー電源７ｂ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 8a protects the light source control device 6 when a current of a predetermined value or more flows from the ignition power supply 7a, and is formed so that the wiring is blown by the current of the predetermined value or more.
The fuse 8b protects the light source control device 6 when a current of a predetermined value or more flows from the accessory power supply 7b, and is formed so that the wiring is blown by the current of the predetermined value or more.
　リレースイッチ１０は、イグニッション電源７ａと昼間走行灯５との間に配置され、可動接点１０ａと、固定接点１０ｂと、固定接点１０ｃとを有する。可動接点１０ａは、ヒューズ８ａを介してイグニッション電源７ａに接続されると共に、固定接点１０ｃに切り換え可能に固定接点１０ｂに接続されている。固定接点１０ｂは、昼間走行灯５に接続されている。固定接点１０ｃ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１０は、可動接点１０ａが固定接点１０ｂに接続された場合には、イグニッション電源７ａを昼間走行灯５に接続するオン状態となる。また、リレースイッチ１０は、可動接点１０ａが固定接点１０ｃに接続された場合には、イグニッション電源７ａを昼間走行灯５に接続しないオフ状態となる。 The relay switch 10 is arranged between the ignition power supply 7a and the daytime traveling light 5, and has a movable contact 10a, a fixed contact 10b, and a fixed contact 10c. The movable contact 10a is connected to the ignition power supply 7a via the fuse 8a, and is also connected to the fixed contact 10b so as to be switchable to the fixed contact 10c. The fixed contact 10b is connected to the daytime traveling light 5. The fixed contact 10c is arranged in a non-conducting state. That is, when the movable contact 10a is connected to the fixed contact 10b, the relay switch 10 is turned on to connect the ignition power source 7a to the daytime traveling light 5. Further, when the movable contact 10a is connected to the fixed contact 10c, the relay switch 10 is in an off state in which the ignition power supply 7a is not connected to the daytime traveling light 5.
　リレーコイル１２は、アクセサリー電源７ｂと操作スイッチ１３との間に配置され、通電によりリレースイッチ１０をオフ状態に切り換える、すなわち可動接点１０ａを固定接点１０ｃに接続するように切り換える。また、リレーコイル１２は、配線９ａから分岐して延びる配線９ｂにより、保護ダイオード１１ａおよびヒューズ８ａを介してイグニッション電源７ａにさらに接続されている。
　ここで、アクセサリー電源７ｂは、配線９ａが分岐する分岐点Ｐ１からリレーコイル１２に延びる配線９ｂに接続点Ｐ２で接続されている。すなわち、アクセサリー電源７ｂは、配線９ｂにおいて分岐点Ｐ１とリレーコイル１２との間に接続されている。 The relay coil 12 is arranged between the accessory power supply 7b and the operation switch 13, and switches the relay switch 10 to the off state by energization, that is, switches the movable contact 10a so as to be connected to the fixed contact 10c. Further, the relay coil 12 is further connected to the ignition power supply 7a via the protection diode 11a and the fuse 8a by the wiring 9b branched from the wiring 9a.
Here, the accessory power supply 7b is connected to the wiring 9b extending from the branch point P1 at which the wiring 9a branches to the relay coil 12 at the connection point P2. That is, the accessory power supply 7b is connected between the branch point P1 and the relay coil 12 in the wiring 9b.
　リレー抵抗１４は、リレーコイル１２への通電が停止した際にリレーコイル１２に持続的に流れる電流を消費するためのものである。
　このリレースイッチ１０、リレーコイル１２およびリレー抵抗１４によりリレー回路１５が構成される。 The relay resistor 14 is for consuming the current that continuously flows through the relay coil 12 when the energization of the relay coil 12 is stopped.
The relay circuit 15 is composed of the relay switch 10, the relay coil 12, and the relay resistor 14.
　保護ダイオード１１ａは、配線９ｂにおいて分岐点Ｐ１と接続点Ｐ２との間に配置され、接続点Ｐ２から分岐点Ｐ１側へ電流が流れることを抑制する。
　保護ダイオード１１ｂは、配線９ｃにおいてアクセサリー電源７ｂと接続点Ｐ２との間に配置され、接続点Ｐ２からアクセサリー電源７ｂ側へ電流が流れることを抑制する。 The protection diode 11a is arranged between the branch point P1 and the connection point P2 in the wiring 9b, and suppresses the flow of current from the connection point P2 to the branch point P1 side.
The protection diode 11b is arranged between the accessory power supply 7b and the connection point P2 in the wiring 9c, and suppresses the flow of current from the connection point P2 to the accessory power supply 7b side.
　操作スイッチ１３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コイル１２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１３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 13 is switched according to the operation of the parking brake 3b, and one contact is connected to the relay coil 12 and the other contact is grounded. Here, the operation switch 13 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１３は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７ａおよびアクセサリー電源７ｂがオフ状態となる。このため、イグニッション電源７ａからリレースイッチ１０を介して昼間走行灯５に給電されず、昼間走行灯５は消灯した状態となる。 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 13 is turned on by the operation of the parking brake 3b, and the ignition power supply 7a and the accessory power supply 7b are turned off when the key operation unit 3a is located at the "LOCK" position. Therefore, the ignition power source 7a does not supply power to the daytime traveling light 5 via the relay switch 10, and the daytime traveling light 5 is turned off.
　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「ＡＣＣ」位置を介して「ＯＮ」位置に切り換えることにより、イグニッション電源７ａおよびアクセサリー電源７ｂが入れられる。 Subsequently, the driver switches the key operation unit 3a to the "ON" position via the "ACC" position while the parking brake 3b is activated, so that the ignition power supply 7a and the accessory power supply 7b are turned on.
　ここで、図３に示すように、アクセサリー電源７ｂとの接続を除く、すなわちイグニッション電源７ａからの通電のみによりリレー回路１５を制御する場合には、イグニッション電源７ａからリレーコイル１２に通電される一方、イグニッション電源７ａからリレースイッチ１０にも通電される。リレーコイル１２に通電されることにより、リレースイッチ１０は、可動接点１０ａが固定接点１０ｂから固定接点１０ｃ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１０ａが固定接点１０ｃに切り換えられるまでの間、イグニッション電源７ａ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 connection with the accessory power supply 7b is excluded, that is, when the relay circuit 15 is controlled only by energization from the ignition power supply 7a, the relay coil 12 is energized from the ignition power supply 7a. , The ignition power supply 7a also energizes the relay switch 10. When the relay coil 12 is energized, the relay switch 10 is turned off by switching the movable contact 10a from the fixed contact 10b to the fixed contact 10c. However, since the ignition power source 7a supplies power to the daytime traveling light 5 until the movable contact 10a is switched to the fixed contact 10c, 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、分岐点Ｐ１とリレーコイル１２との間にアクセサリー電源７ｂを接続する。ここで、鍵操作部３ａの「ＡＣＣ（アクセサリー）」位置は、「ＬＯＣＫ（ロック）」位置に対して「ＯＮ（オン）」位置より手前に配置されている。このため、アクセサリー電源７ｂは、鍵操作部３ａの操作によりイグニッション電源７ａより前にオン状態とされる。
　これにより、リレーコイル１２は、イグニッション電源７ａがオン状態とされる前に、アクセサリー電源７ｂから通電されることになる。このため、図４に示すように、イグニッション電源７ａから昼間走行灯５に給電される前に、リレースイッチ１０が可動接点１０ａを固定接点１０ｃに接続するオフ状態に切り換えられる。 Therefore, as shown in FIG. 2, the accessory power supply 7b is connected between the branch point P1 and the relay coil 12. Here, the "ACC (accessory)" position of the key operation unit 3a is arranged in front of the "ON" position with respect to the "LOCK" position. Therefore, the accessory power supply 7b is turned on before the ignition power supply 7a by the operation of the key operation unit 3a.
As a result, the relay coil 12 is energized from the accessory power supply 7b before the ignition power supply 7a is turned on. Therefore, as shown in FIG. 4, the relay switch 10 is switched to the off state in which the movable contact 10a is connected to the fixed contact 10c before the ignition power supply 7a supplies power to the daytime traveling light 5.
　すなわち、操作スイッチ１３がオン状態の場合には、イグニッション電源７ａより前にオン状態とされたアクセサリー電源７ｂからリレーコイル１２に通電されて、リレースイッチ１０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７ａから昼間走行灯５への給電が持続的に停止される。
　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７ａ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、分岐点Ｐ１とリレーコイル１２との間にアクセサリー電源７ｂを接続した簡単な構成で、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 13 is in the on state, the relay coil 12 is energized from the accessory power supply 7b that was turned on before the ignition power supply 7a, and the relay switch 10 is switched to the off state, so that the ignition power supply 7a is turned on. The power supply 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 7a 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 accessory power supply 7b is connected between the branch point P1 and the relay coil 12.
　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１３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 13 is turned off.
　操作スイッチ１３がオフ状態になることにより、イグニッション電源７ａおよびアクセサリー電源７ｂからリレーコイル１２への通電が遮断されて、リレースイッチ１０が可動接点１０ａを固定接点１０ｂ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１０を介してイグニッション電源７ａから昼間走行灯５に給電される。 When the operation switch 13 is turned off, the energization from the ignition power supply 7a and the accessory power supply 7b to the relay coil 12 is cut off, and the relay switch 10 is switched to the on state in which the movable contact 10a is connected to the fixed contact 10b. As a result, power is supplied from the ignition power source 7a to the daytime traveling light 5 via the relay switch 10.
　このように、イグニッション電源７ａと昼間走行灯５の間にリレー回路１５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１４が、リレーコイル１２への通電が遮断された際に、リレーコイル１２に流れる電流を消費するため、リレースイッチ１０を速やかにオン状態に切り換えることができる。 As described above, the daytime traveling light 5 can be automatically turned on with a simple configuration in which the relay circuit 15 is arranged between the ignition power source 7a 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 14 consumes the current flowing through the relay coil 12 when the energization of the relay coil 12 is cut off, the relay switch 10 can be quickly switched to the ON state.
　また、保護ダイオード１１ａが、分岐点Ｐ１と接続点Ｐ２との間に配置されているため、アクセサリー電源７ｂから接続点Ｐ２を介して分岐点Ｐ１側に電流が流れることを抑制し、昼間走行灯５を安定して点灯させることができる。
　また、保護ダイオード１１ｂが、アクセサリー電源７ｂと接続点Ｐ２との間に配置されているため、イグニッション電源７ａから接続点Ｐ２を介してアクセサリー電源７ｂ側に電流が流れることを抑制し、アクセサリー電源７ｂからリレーコイル１２への通電を維持することができる。 Further, since the protection diode 11a is arranged between the branch point P1 and the connection point P2, it is possible to suppress the current from flowing from the accessory power supply 7b to the branch point P1 side via the connection point P2, and to suppress the flow of the current to the branch point P1 side. 5 can be lit stably.
Further, since the protection diode 11b is arranged between the accessory power supply 7b and the connection point P2, the current does not flow from the ignition power supply 7a to the accessory power supply 7b side via the connection point P2, and the accessory power supply 7b is suppressed. It is possible to maintain the current supply to the relay coil 12.
　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１３がオン状態とされる。これにより、イグニッション電源７ａおよびアクセサリー電源７ｂからリレーコイル１２に通電されて、リレースイッチ１０がオフ状態に切り換えられる。リレースイッチ１０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７ａ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 13 is turned on. As a result, the relay coil 12 is energized from the ignition power supply 7a and the accessory power supply 7b, and the relay switch 10 is switched to the off state. When the relay switch 10 is switched to the off state, the power supply from the ignition power source 7a 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１３がオン状態の場合には、アクセサリー電源７ｂからリレーコイル１２に通電されて、リレースイッチ１０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７ａ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７ａを入れた直後に、イグニッション電源７ａ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 13 is in the ON state, the relay coil 12 is energized from the accessory power source 7b, and the relay switch 10 is switched to the OFF state, so that the ignition power source 7a is used for the daytime traveling light 5. Power supply to is stopped. As a result, immediately after operating the key operation unit 3a to turn on the ignition power source 7a, it is possible to suppress the electrical connection between the ignition power source 7a and the daytime traveling light 5 and ensure that the daytime traveling light 5 is lit. Can be controlled.
　なお、本実施の形態では、リレーコイル１２は、イグニッション電源７ａとアクセサリー電源７ｂに接続されたが、アクセサリー電源７ｂと操作スイッチ１３との間に配置されていればよく、これに限られるものではない。
　例えば、図６に示すように、保護ダイオード１１ａおよび１１ｂを除くと共に、配線９ａ～９ｃに換えて新たな配線２１ａおよび２１ｂを配置することができる。一般的に、鍵操作部３ａが「ＳＴＡＲＴ」位置にある場合はアクセサリー電源７ｂが遮断されるが、鍵操作部３ａが「ＳＴＡＲＴ」位置にある場合でもアクセサリー電源７ｂが遮断されない構造とすることにより、以下のような構成が可能となる。 In the present embodiment, the relay coil 12 is connected to the ignition power supply 7a and the accessory power supply 7b, but it may be arranged between the accessory power supply 7b and the operation switch 13, and the present invention is not limited to this. No.
For example, as shown in FIG. 6, the protection diodes 11a and 11b can be removed, and new wirings 21a and 21b can be arranged in place of the wirings 9a to 9c. Generally, the accessory power supply 7b is shut off when the key operation unit 3a is in the "START" position, but the accessory power supply 7b is not shut off even when the key operation unit 3a is in the "START" position. , The following configurations are possible.
　配線２１ａは、ヒューズ８ａを介してイグニッション電源７ａをリレースイッチ１０の可動接点１０ａに接続するものである。
　配線２１ｂは、ヒューズ８ｂを介してアクセサリー電源７ｂをリレーコイル１２に接続するものである。 The wiring 21a connects the ignition power supply 7a to the movable contact 10a of the relay switch 10 via the fuse 8a.
The wiring 21b connects the accessory power supply 7b to the relay coil 12 via the fuse 8b.
　すなわち、配線２１ａおよび２１ｂは、分岐されることなく、イグニッション電源７ａをリレースイッチ１０のみに接続すると共にアクセサリー電源７ｂをリレーコイル１２のみに接続するものである。 That is, the wirings 21a and 21b connect the ignition power supply 7a only to the relay switch 10 and the accessory power supply 7b only to the relay coil 12 without being branched.
　このような構成により、鍵操作部３ａが「ＬＯＣＫ（ロック）」位置から「ＡＣＣ」位置を介して「ＯＮ」位置に切り換えると、イグニッション電源７ａがオン状態とされる前に、アクセサリー電源７ｂから配線２１ｂを介してリレーコイル１２に通電される。これにより、イグニッション電源７ａから昼間走行灯５に給電される前に、リレースイッチ１０をオフ状態に切り換えることができ、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７ａをリレースイッチ１０のみに接続すると共にアクセサリー電源７ｂをリレーコイル１２のみに接続した簡単な構成で、昼間走行灯５の点灯を確実に制御することができる。 With such a configuration, when the key operation unit 3a switches from the "LOCK" position to the "ON" position via the "ACC" position, the accessory power supply 7b is used before the ignition power supply 7a is turned on. The relay coil 12 is energized via the wiring 21b. As a result, the relay switch 10 can be switched to the off state before the ignition power source 7a supplies power to the daytime traveling light 5, and the lighting of the daytime traveling light 5 can be reliably controlled. At this time, the lighting of the daytime traveling light 5 can be reliably controlled by a simple configuration in which the ignition power supply 7a is connected only to the relay switch 10 and the accessory power supply 7b is connected only to the relay coil 12.
　また、本実施の形態では、リレー回路１５は、イグニッション電源７ａ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７ａに限られるものではない。
　また、本実施の形態では、リレー回路１５は、アクセサリー電源７ｂに接続されたが、リレースイッチ１０に接続された電源より前にオン状態とされる電源に接続されていればよく、アクセサリー電源７ｂに限られるものではない。 Further, in the present embodiment, the relay circuit 15 is connected to the ignition power supply 7a, but it is not limited to the ignition power supply 7a as long as it is connected to the vehicle power supply.
Further, in the present embodiment, the relay circuit 15 is connected to the accessory power supply 7b, but may be connected to a power supply that is turned on before the power supply connected to the relay switch 10 and is connected to the accessory power supply 7b. It is not limited to.
　また、本実施の形態では、操作スイッチ１３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 operation switch 13 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１５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 circuit 15 is connected to the daytime traveling light 5, but it is not limited to the daytime traveling light 5 as long as it is connected to the light source of the vehicle.
