And a control switch 120 for switching the power supply of the control device 110.

Further, the additional ignition system 10
0 is a regular user detection unit 130 as a regular user detection unit that detects whether the user who operates the operation switch 120 is a regular user, and a safety that detects whether the vehicle is in a predetermined safe state. It has a safety detector 140 as a detector and a battery voltage detector 150 as a battery voltage detector that detects the voltage value of the battery 20.

The control device 110 is provided at an arbitrary position of the vehicle, and in response to an input from the operation switch 120, the accessory system load 40, the ignition system load 50, and the start system load 60 are electrically connected to the battery. Selectively turn on / off the connection. In the present embodiment, as shown in FIG. 1, the control device 110 is provided electrically in parallel with the ignition switch 10.

The operation switch 120 is used by the user to switch the power supply of the control device 110. The positions where the operation switches 120 are provided and the number of the operation switches 120 are determined by the additional ignition system 100.
Is appropriately determined according to the type and application of the vehicle in which The operation switch 120 may be the operation switch 120 provided at an arbitrary position of the vehicle (for example, a rear seat), or the wireless operation switch 1 separate from the vehicle body.
The number of operation switches 120 may be 1
It may be one or two or more.

The authorized user detecting section 130 is provided at an arbitrary position of the vehicle and has a function of detecting whether or not the user operating the operation switch 120 is an authorized user. The authorized user detection unit 130 is specifically configured to have at least one of the following functions (a) to (d), for example. (A) A function of detecting that a key has been inserted into the key cylinder of the ignition key. (B) A function of detecting that the door is unlocked by keyless entry. (C) A function of detecting that the operation switch 120 has been operated within a predetermined specified time after the ignition switch 10 has been operated. (D) A function of detecting that a predetermined personal identification number is input to the control device 110.

When the above-mentioned predetermined items are detected by the functions (a) to (d), it means that the user is an authorized user. The additional ignition system 100 of the present embodiment is configured so that switching of power supply by the control device 110 is disabled when the user is not an authorized user.

The safety detector 140 is provided at an arbitrary position of the vehicle and has a function of detecting whether or not the vehicle is in a predetermined safe state. The "predetermined safe state" in the specification of the present application refers to a state suitable for switching the power supply by the additional ignition system, and specifically, for example, "state in which vehicle speed is 0 km / h". ,
"The engine speed is 0r / min", "The shift lever is in the P range position", "The parking brake is applied", "The bonnet is closed" and "The door is "Closed". What kind of state corresponds to the “predetermined safe state” is appropriately determined according to the type and application of the vehicle. Specifically, the safety detection unit 140 is configured to have at least one of the following functions (e) to (j), for example. (E) A function of detecting that the vehicle speed is 0 km / h.

3). If the user is not an authorized user, the switching of the power supply by the control device 110 is disabled, and the control by the additional ignition system 100 is stopped (S7).
If the user is an authorized user, then the safety detector 14
Based on 0, it is detected whether the vehicle is in a predetermined safe state (S4).

When the vehicle is not in a predetermined safe state,
The control by the additional ignition system 100 is stopped (S7). When the vehicle is in a predetermined safe state, the battery voltage detection unit 150 subsequently detects the voltage value of the battery (S5).

When the voltage value of the battery is lower than the predetermined value, the control by the additional ignition system 100 is stopped (S7). When the voltage value of the battery is equal to or higher than a predetermined value, the extension ignition system 100
Is started (S6), and power is selectively supplied to the accessory system load 40, the ignition system load 50, and the start system load 60 according to the information input to the operation switch 120.

After the control by the additional ignition system 100 is started (after S6), the information input to the operation switch 120 is read, whether or not the user is an authorized user is detected, and the vehicle is in a predetermined safe state. Detection of the presence or absence and detection of the voltage value of the battery 20 are performed again (S2 to S5), and the control by the additional ignition system 100 is started or stopped according to the detection result (S6 or S7). In addition, after the control by the additional ignition system 100 is stopped (after S7)
, The presence / absence of input to the operation switch is again determined (S1).

In this way, the expansion ignition system 100 of this embodiment operates.

Typically, it is possible to switch so that power is supplied in a cumulative manner in this order.

Next, when the ignition key is at the accessory position, it is possible to control the supply of electric power from the battery 20 to each of the ignition load 50 and the start load 60. At this time, since the accessory system load 40 is supplied with power from the battery 20 by the ignition switch 10, depending on the operation by the additional ignition system 100,
The power supply from the battery 20 to the accessory system load 40 cannot be stopped.

When the ignition key is at the ignition position, the power supply from the battery 20 to the start system load 60 can be controlled.
At this time, since the accessory system load 40 and the ignition system load 50 are supplied with electric power from the battery 20 by the ignition switch 10, the accessory system load 40 and the battery 20 for the ignition system load 20 may be operated by the additional ignition system 100. It is not possible to stop the supply of electric power from.

Further, the expansion ignition system 100 of the present embodiment has a regular user detecting section 130 as a regular user detecting means for detecting whether or not the user operating the operating switch 120 is a regular user. When the user who operates 120 is not an authorized user, switching of power supply by the control device 110 is disabled. Therefore, since the operation by the non-authorized user is disabled, the engine is prevented from being started by the operation by the non-authorized user. Therefore, when the additional ignition system 100 according to the present invention is used in a vehicle, a vehicle having excellent security is provided.

Further, the additional ignition system 100 of the present embodiment has a safety detecting section 140 as a safety detecting means for detecting whether or not the vehicle is in a predetermined safe state, and the vehicle is in a predetermined safe state. If it is not, switching of power supply by the control device 110 is disabled. Therefore, if the vehicle is not in a predetermined safe state, that is, if the vehicle is not suitable for operating the additional ignition system, the additional ignition system cannot be operated. Therefore, when the additional ignition system 100 according to the present invention is used in a vehicle, a vehicle having excellent safety is provided.

The additional ignition system 100 of this embodiment has the battery voltage detection unit 150 as a battery voltage detection means for detecting the voltage value of the battery 20, and when the voltage value of the battery 20 is lower than the predetermined value. Is configured so that switching of power supply by the control device 110 is disabled. Therefore, the operation of the additional ignition system 100 cannot be performed when the voltage value of the battery 20 is lower than the predetermined value, so that the rise of the battery is prevented.
