  Hereinafter, embodiments will be described in detail with reference to the drawings.

  FIG. 1 shows a system control apparatus 10 according to the present embodiment. This system control device 10 controls the operation of an automobile engine start system 70.

  The system control apparatus 10 according to the present embodiment includes an ECU 20 (Electronic Control Unit) that constitutes a control apparatus main body and a remote control engine starter 30 that is a separate body. In addition, ECU20 is mounted in a motor vehicle, while remote control engine starter 30 is carried by the operator.

  The ECU 20 is composed of a microcomputer including a CPU 21 (Central Processing Unit), a storage unit 22, a receiving unit 23, and the like.

  Each unit such as a storage unit 22 and a reception unit 23 is connected to the CPU 21 inside the ECU 20.

  The storage unit 22 stores a computer program to be executed by the CPU 21, on / off switching history information of the hood switch 40, and the like.

  The receiving unit 23 is configured to receive a signal from a transmitting unit 32 of a remote control engine starter 30 described later.

  The ECU 20 is connected to the hood switch 40, the door opening / closing detection unit 50, the shift lever position detection unit 60, and the engine start system 70. A connector 41 is interposed in the wiring with the hood switch 40.

  The hood switch 40 is configured to be in an on state when the hood is open and to be in an off state when the hood is closed. Since one of the wires extending from the connector 41 on the ECU 20 side is grounded, the potential input from the wire connected to the ECU 20 changes depending on whether the hood switch 40 is in the on state or the off state. Thus, the open / close state of the hood can be detected by the ECU 20.

  The door open / close detection unit 50 is configured so that the ECU 20 can detect the open / closed state of the door by a signal from the door open / close detection unit 50.

  The shift lever position detection unit 60 detects by the ECU 20 whether the position of the shift lever is in the parking (P), back (R), neutral (N), drive (D), or the like based on a signal from the bottom. It is configured to be able to.

  The engine start system 70 is configured to start the engine in a predetermined case such as when a user (driving person) turns on an ignition switch.

  Connections between the ECU 20 and the outside of the ECU 20 are respectively connected to the CPU 21 inside the ECU 20.

  The ECU 20 is connected to a battery (not shown).

  The remote control engine starter 30 includes an engine start switch 31 and a transmission unit 32 that transmits a signal thereof. Accordingly, the remote control engine starter 30 constitutes a remote operation means for remotely operating the operation control of the engine start system 70.

  Next, the control operation by the system control apparatus 10 will be described based on the flowcharts of FIGS. The control operation by the system control device 10 is performed by the CPU 21 executing information processing based on a computer program stored in the storage unit 22. This computer program is recorded on a computer-readable recording medium such as a CD-ROM or DVD and can be established as a product alone.

  When the engine start switch 31 of the remote control engine starter 30 is pressed, the signal is transmitted from the transmission unit 32, and the reception unit 23 of the ECU 20 receives the signal, which becomes the starting point and the CPU 21 executes the computer program. Start.

  First, in step A1, it is determined whether the door is open based on a signal from the door opening / closing detection unit 50. If YES, the process ends. If NO, the process proceeds to step A2.

  In step A2, it is determined whether or not the shift lever is in the parking (P) position based on a signal from the shift lever position detection unit 60. If YES, the process proceeds to step A3. If NO, the process ends. To do.

  In step A3, the switching history of the hood switch 40 is read from the storage unit 22 and the presence / absence of the switching history is read, so that there is a switching history, that is, a history of switching the hood switch 40 from the off state to the on state. If it is read, the process proceeds to step A4. If it is read that there is no switching history, the process jumps to step B1 of the subroutine for determining the hood switch switching history shown in FIG.

  Accordingly, the storage unit 22 constitutes a switching history information storage unit that stores on / off switching history information of the hood switch 40. In addition, the information processing of step A3 by the CPU 21 constitutes a switching history presence / absence reading unit that reads the presence / absence of the switching history from the switching history information of the storage unit 22, and the presence / absence of the switching history from the switching history information of the storage unit 22 in the computer program. Corresponds to a switching history presence / absence reading procedure.

  In step A4, it is determined whether or not the hood is open based on a signal from the hood switch 40. If YES, that is, if it is detected that the hood switch 40 is on and the hood is open. If NO, that is, if it is detected that the hood switch 40 is OFF and the hood is closed, the process proceeds to step A5.

  Therefore, the information processing of step A4 by the CPU 21 constitutes an on / off detection means for detecting the on / off state of the hood switch 40 and an on / off detection procedure for detecting the on / off state of the hood switch 40 in the computer program. It corresponds to.

  In step A5, the engine start system 70 is operated to start the engine, and the program is terminated.

  Therefore, the information processing in step A5 by the CPU 21 detects that the door is not open, detects that the shift lever is in the parking (P) position, and switches the hood switch 40 on / off. A computer program that constitutes system operating means for operating the engine starting system 70 when a certain condition of having a history and detecting that the hood switch 40 is OFF and the hood is closed is satisfied This corresponds to a system operating procedure for operating the engine starting system 70 when these certain conditions are satisfied.

  In step B1 of the subroutine, it is determined whether or not the hood switch 40 is on based on a signal from the hood switch 40. If YES, the process proceeds to step B2. If NO, the process returns to step B1.

  Here, in this case, since there is no on / off switching history of the hood switch 40 until this stage, it means that the hood switch 40 was in the off state, but the on state of the hood switch 40 was detected. This means that the hood switch 40 has been switched from the off state to the on state. Therefore, the information processing in step B1 by the CPU 21 constitutes a switching detection means for detecting the on / off switching of the hood switch 40 and corresponds to a switching detection procedure for detecting the on / off switching of the hood switch 40 in the computer program. To do.

  In step B2, the switching history information in the storage unit 22 is rewritten from no switching history to switching history, and the process ends.

  Therefore, the information processing of step B2 by the CPU 21 constitutes switching history information rewriting means for rewriting the switching history information in the storage unit 22 from no switching history to the presence of switching history, and the switching history information in the storage unit 22 in the computer program is switched. This corresponds to a switching history information rewriting procedure for rewriting from none to switching history.

  According to the system control apparatus 10 having the above configuration, the connection of the hood switch 40 is unconfirmed if there is no switching history due to the presence / absence of the switching history of the hood switch 40, and if there is a switching history, the hood It can be determined that the connection of the switch 40 has been confirmed. In the former case, when switching of the hood switch 40 is detected, the switching history information in the storage unit 22 is rewritten from no switching history to switching history. Next time, it is determined that the connection of the hood switch 40 has been confirmed. In the latter case, it is confirmed that the hood switch 40 is connected, so that the on / off state of the hood switch 40 is in the off state. The engine start system 70 can be activated if certain conditions are met, including some.

  Such a configuration is particularly useful in automobile factories. For example, in the assembly process, if there is a disconnection between the ECU 20 and the hood switch 40 due to forgetting to connect the connector 41, the hood switch 40 is connected even if the hood is opened to the closed state. Since the same signal that the off state was maintained from the beginning to the end is input to the ECU 20 from the wiring that should have been, the engine start inspection by the remote control engine starter 30 is performed in the inspection process. Even if it is detected that the door is not open at A1 and the shift lever is at the parking (P) position at Step A2, the engine will start waiting at Step B1, and the engine start system 70 will not be started. Thereby, disconnection of the hood switch 40 is detected. Door can be. When the disconnection of the hood switch 40 is corrected, the hood is opened and the work is performed. If the disconnection of the hood switch 40 is corrected, the process proceeds from step B1 to step B2, and the storage unit 22 is switched. When the history information is rewritten from no switching history to the switching history, and then the hood is closed, the hood switch 40 is turned off, and when the engine start inspection is performed again by the remote control engine starter 30, The engine starting system 70 can be started via Step A1-Step A2-Step A3-Step A4-Step A5. Therefore, the information processing of the subroutine shown in FIG. 3 is basically performed only once in the automobile factory, and the operation control of the engine starting system 70 using the remote control engine starter 30 by the end user is performed according to the information processing of the flowchart shown in FIG. Is done.

  Further, since the disconnection of the connector 41 does not occur while the vehicle is running, once the connection of the hood switch 40 is confirmed once in the automobile factory as described above, when the remote control engine starter 30 is operated, a person other than the operator Even when the hood is opened for maintenance and inspection, the hood switch 40 is reliably turned on, so the engine does not start. Therefore, it is possible to avoid a risk that the engine is started in a state where the hood is open due to a misjudgment caused by disconnection of the hood switch 40.

  In the present embodiment, the system control device 10 that controls the operation of the engine start system 70 is used. However, the present invention is not particularly limited to this. For example, the system control device may be a keyless entry system or a light control system. Good.

  In this embodiment, the presence / absence of the on / off switching history of the hood switch 40 is detected. However, the present invention is not particularly limited to this. For example, on / off switching of a door switch or a trunk switch is performed. The structure which detects the presence or absence of a log | history may be sufficient.

  In the present embodiment, the hood switch 40 is turned off when the hood is closed, and the hood switch 40 is turned on when the hood is opened. However, the present invention is not limited to this. The hood switch 40 may be turned on when the hood is closed, and the hood switch 40 may be turned off when the hood is open. However, the configuration of the present embodiment is preferable from the viewpoint that there is no power consumption when the hood, which is a normal state, is closed.

  In the present embodiment, the remote control engine starter 30 which is a remote control means configured separately from the ECU 20 which is the main body of the control device is configured to remotely operate the operation control of the engine start system 70. A configuration without the remote control engine starter 30 as a means may be used.
