Abstract
Description
[Technical field]
[0001] The present invention relates to a vehicle control device that controls a display device provided in a vehicle. [Background technology]
[0002] Conventionally, vehicles are provided with fuses to protect the mounted electrical devices (for example, Patent Document 1). The fuses are provided in the circuits of the electrical devices (for example, in the power supply lines) and melt to protect the circuits when an overcurrent occurs due to an abnormality in the circuits. Since fuses are required not to melt under normal operating conditions, the lifespan of the fuses may be estimated and the fuses may be replaced periodically. Patent Document 1 discloses a technology that estimates the lifespan of a fuse based on a calculated resistance value of the fuse and notifies the user of fuse degradation.

[0003] [Patent Document 1] JP 2017-147844 A Summary of the Invention [Problem to be solved by the invention]
[0004] Meanwhile, electronic devices mounted on vehicles, such as ECUs that perform various controls and car navigation systems, may be provided with a backup power supply to maintain memory contents even when the ignition switch is turned off. In this case, a standby current is consumed even when the ignition switch is turned off, which may cause the battery to deteriorate. Therefore, a fuse (backup fuse) may be provided in the supply line of the backup power supply, and the fuse may be removed to prevent standby current when the vehicle is transported or stored for a long period of time.
[0005] However, for example, if a backup fuse is provided in a display device such as a car navigation system, a display audio, or other liquid crystal panel, the display device will be unable to display anything if the backup fuse is removed during transportation or long-term storage. In this case, even if there is useful information that would be useful to display on the display device when the car is moved temporarily during transportation, it will not be displayed.
[0006] Therefore, it is conceivable to provide another power line, such as a power line that is conductive when the ignition switch is ON, so that the display can continue to display information even when the backup fuse is removed. However, during transportation or long-term storage, there are items that do not need to be displayed on the display and items that do, and convenience can be improved by changing the display content according to the situation.
[0007] The present invention has been made in consideration of the above-mentioned problems, and aims to improve convenience by determining the insertion / removal state of a fuse connected to a power line of a display device and changing the display content depending on the determination result. [Means for solving the problem]
[0008] In order to achieve the above object, a vehicle control device according to the present invention is a vehicle control device that controls a display device arranged in a vehicle, comprising: a first display device capable of displaying the ON / OFF states of a driving assistance function, a skid prevention function, and an idling stop function; a second display device made of a non-touch panel type liquid crystal panel capable of displaying the ON / OFF states of at least one of the driving assistance function, the skid prevention function, and the idling stop function; and a steering switch for operating the ON / OFF of the functions displayed on the second display device; The above The first display device and the second display device Display device control means for controlling the display device and The method comprises the steps of: 1. Display device power supply line teeth, The fuse is connected so that it can be inserted and removed. Connecting the first display device to a battery First power supply line a fuse is removably connected to a power supply line of the second display device, and the second display device is connected to a battery. Second Power Supply Line having The display device control means The first power supply line determining whether the fuse is inserted or removed; When it is determined that the fuse of the first power supply line is inserted, the second display device does not display any ON / OFF state of the driving assistance function, the skid prevention function, and the idling stop function, and when it is determined that the fuse of the first power supply line is removed, the second display device displays the ON / OFF state of at least one of the driving assistance function, the skid prevention function, and the idling stop function, thereby enabling the steering switch to turn on / off the corresponding function. It is characterized by do. Effect of the Invention
[0011] BooksAccording to the invention, When the fuse of the first power supply line of the first display device is removed, the display contents of the second display device display at least one of the ON / OFF states of the driving assistance function, the skid prevention function, and the idling stop function, which are not displayed on the second display device when the fuse is inserted. Therefore, for example, when the fuse of the first power supply line of the first display device is removed, the ON / OFF state of at least one of the driving assistance function, the skid prevention function, and the idling stop function, which are the display contents of the first display device, can be displayed on the second display device, and the ON / OFF state of the functions displayed on the second display device can be operated. Convenience is improved. Also, for example, if the fuse of the first power supply line of the first display device is removed and the display is to be made only when the ignition switch is in the ON state, it is necessary to provide the first display device with a separate power line that forms a power circuit that is conductive only when the ignition switch is in the ON state. In this case, it becomes necessary to provide a separate power circuit and harness for the first display device, which leads to increases in cost and weight, but this can be prevented from increasing cost and weight. [Brief description of the drawings]
[0014] [Figure 1] 1 is a schematic configuration diagram of a vehicle control device according to an embodiment of the present invention; [Diagram 2] 2 is a diagram for explaining the operation of the vehicle control device of FIG. 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] A vehicle control device according to one embodiment of the present invention will be described with reference to Figures 1 and 2. Figure 1 is a schematic configuration diagram of the vehicle control device according to one embodiment of the present invention, and Figure 2 is a diagram for explaining the operation of the vehicle control device.
[0016] (Vehicle Electrical Configuration) The vehicle control device according to one embodiment of the present invention is disposed in a vehicle 1 and includes a battery 2 that supplies power to various electronic devices, a CID (Center Information Display) 3, a meter display 4, a steering switch 5 provided on the steering wheel, and an integrated cockpit ECU 10 that controls the display of the CID 3 and the meter display 4.
[0017] CID3 (corresponding to the "first display device" of the present invention) is a display device that displays various information and switches, and is disposed in the center of the instrument panel. CID3 has a touch panel configuration and includes a liquid crystal panel and a position detection means that detects the position when the liquid crystal panel is pressed and transmits the position information to the CPU 10a of the integrated cockpit ECU 10.
[0018] The information displayed on the display screen of CID3 is, for example, a car navigation map display and fuel efficiency information, and the switches are a driving support function ON / OFF setting switch, a vehicle stability control (VSC) ON / OFF setting switch, an air conditioner adjustment operation switch, and an idling stop function ON / OFF setting switch. Note that CID3 does not have to be configured as a touch panel, and may be displayed as a hardware switch configuration.
[0019] Each switch is displayed in a specific area on the display screen, and when a user presses the specific area, a press signal including position information is transmitted to the CPU 10a of the integrated cockpit ECU 10. The data of the display image of CID 3 is stored, for example, in the memory 10b of the integrated cockpit ECU 10, and the CPU 10a of the integrated cockpit ECU 10 selects image data from the memory 10b and displays it on CID 3. The display image data may be stored in a memory (not shown) provided in CID 3, and the CPU (not shown) of CID 3 may select image data specified by the CPU 10a of the integrated cockpit ECU 10 from the memory and display it on the display screen.
[0020] CID 3 is driven by power supplied from battery 2. In this embodiment, two lines are provided as paths for supplying power to CID 3: a backup power line L1 (corresponding to the "first power supply line" of the present invention) and an ACC power line L2. Backup power line L1 is a line that directly connects battery 2 and a power terminal of CID 3 without passing through any other circuit. In addition, a backup fuse 20a is connected in series to backup power line L1.
[0021] Backup fuse 20a (corresponding to the "fuse" of the present invention) is formed, for example, from a plate-shaped or wire-shaped metal, and is connected, for example, in series to the positive line between battery 2 and the power supply terminal of CID 3. The metal forming backup fuse 20a melts and cuts off backup power supply line L1 when a current of a predetermined value or more flows.
[0022] The ACC (accessory) power line L2 is a line that connects the battery 2 and the power terminal of the CID 3 via the ACC power circuit. The ACC power circuit is a circuit that makes the ACC power line L2 conductive when the ACC power switch is ON and cuts off the ACC power line L2 when the ACC power switch is OFF. In addition, an ACC fuse 20b is connected in series to the ACC power line L2.
[0023] The ACC fuse 20b is formed of, for example, a plate-shaped or wire-shaped metal, and is connected in series, for example, to the positive line between the battery 2 and the power supply terminal of CID 3. The metal forming the ACC fuse 20b melts and cuts off the ACC power supply line L2 when a current of a predetermined value or more flows. Therefore, when the ACC fuse 20b is inserted in a normal state, power is supplied from the battery 2 to CID 3 when ACC is ON.
[0024] According to this configuration, even if the ignition switch (not shown) is OFF or the ACC power switch is OFF, if a normal backup fuse 20a is inserted into the backup power line L1, power (backup power) is supplied to CID3 from the battery 2.
[0025] The meter display 4 (corresponding to the "second display device" of the present invention) is a display device that displays various information and ON / OFF buttons for various functions (e.g., driving support function (SCM), vehicle stability control function (VSC), etc.), and includes measuring instruments such as a vehicle speedometer and a tachometer on the driver's seat side of the instrument panel. The meter display 4 is, for example, configured with a non-touch panel type liquid crystal panel, and when ON / OFF setting buttons for functions described later are displayed, ON / OFF is designated by operating a steering switch 5 installed on the steering wheel. The measuring instruments such as the vehicle speedometer and the tachometer may be configured separately from the meter display 4. Specifically, the meter display 4 and the measuring instruments such as the vehicle speedometer and the tachometer may be disposed adjacent to each other on the driver's seat side of the instrument panel.
[0026] The information displayed on the display screen of the meter display 4 includes, for example, the ON / OFF state of the illumination function in the vehicle cabin, the volume setting of the car stereo, etc. The illumination function is a function that can change the lighting color and the on / off state of lighting devices such as color LEDs arranged in the vehicle cabin.
[0027] When ignition power is supplied with the backup fuse 20a removed, some of the contents that would normally be displayed on the display screen of the CID 3 are displayed on the display screen of the meter display 4. In this embodiment, the some of the contents are a driving assistance function ON / OFF setting button, a vehicle stability control function (VSC) ON / OFF setting button, and an idling stop function ON / OFF setting button, which will be described in detail later.
[0028] The steering switch 5 is composed of a number of switches, such as a switch for moving an item specification cursor displayed on the display screen, an enter switch, a return switch, a volume setting switch, and an ON / OFF switch for the illumination function.
[0029] The data of the display image of the meter display 4 is stored, for example, in the memory 10b of the integrated cockpit ECU 10, and the CPU 10a of the integrated cockpit ECU 10 selects image data from the memory 10b and displays it on the meter display 4. The display image data may be stored in a memory (not shown) provided in the meter display 4, and the CPU (not shown) of the meter display 4 may select image data specified by the CPU 10a of the integrated cockpit ECU 10 from the memory and display it on the display screen.
[0030] The meter display 4 is driven by power supplied from the battery 2. In this embodiment, three lines are provided as paths for supplying power to the meter display 4: a backup power line L3, an IG power line L4 (corresponding to the "second power supply line" of the present invention), and an ACC power line L5. The backup power line L3 is a line that directly connects the battery 2 and the power terminal of the meter display 4 without passing through any other circuit. In addition, a backup fuse 30a is connected in series to the backup power line L3.
[0031] The backup fuse 30a is formed of, for example, a plate-shaped or wire-shaped metal, and is connected in series, for example, to a positive line between the battery 2 and a power terminal of the meter display 4. The metal forming the backup fuse 30a melts and cuts off the backup power line L3 when a current of a predetermined value or more flows.
[0032] The IG (ignition) power supply line L4 is a line that connects the battery 2 and a power terminal of the meter display 4 via an IG power supply circuit. The IG power supply circuit is a circuit that makes the IG power supply line L4 conductive when the ignition switch is ON and cuts off the IG power supply line L4 when the ignition switch is OFF. In addition, an IG fuse 30b is connected in series to the IG power supply line L4.
[0033] The IG fuse 30b is formed of, for example, a plate-shaped or wire-shaped metal, and is connected in series, for example, to the positive line between the battery 2 and the power supply terminal of the meter display 4. The metal forming the IG fuse 30b melts and cuts off the IG power supply line L4 when a current of a predetermined value or more flows. Therefore, when the IG fuse 30b is inserted in a normal state, power is supplied from the battery 2 to the meter display 4 when the ignition switch is ON.
[0034] The ACC (accessory) power line L5 is a line that connects the battery 2 and the power terminal of the meter display 4 via an ACC power circuit. The ACC power circuit is a circuit that makes the ACC power line L5 conductive when the ACC power switch is ON and cuts off the ACC power line L5 when the ACC power switch is OFF. In addition, an ACC fuse 30c is connected in series to the ACC power line L5.
[0035] The ACC fuse 30c is formed of, for example, a plate-like or wire-like metal, and is connected in series, for example, to the positive line between the battery 2 and the power terminal of the meter display 4. The metal forming the ACC fuse 30c melts and cuts off the ACC power line L5 when a current of a predetermined value or more flows. Therefore, when the ACC fuse 30c is inserted in a normal state, power is supplied from the battery 2 to the meter display 4 when the ACC is ON.
[0036] According to this configuration, even if the ignition switch (not shown) is in the OFF position or the ACC power switch is in the OFF position, if a normal backup fuse 30a is inserted in the backup power line L3, power (backup power) is supplied to the meter display 4 from the battery 2.
[0037] The integrated cockpit ECU 10 controls the display of the CID 3 and the meter display 4, and has a CPU 10a (corresponding to the "display device control means" of the present invention) that performs various controls and various calculations, a memory 10b that stores various programs and image data for the CID 3 and the meter display 4, and the like.
[0038] (CID display screen control) For example, when a user presses the display area of a car navigation icon displayed on the home screen of CID3, the CPU 10a of the integrated cockpit ECU 10 determines that the user has specified the car navigation system based on the press signal (including press position information) transmitted from CID3, and selects map image data of the car navigation system from memory 10b and displays it on CID3.
[0039] Furthermore, when the user presses the display area of the ON button for the driving support function (the "SCM" ON button) displayed on the home screen of CID3, the CPU 10a of the integrated cockpit ECU 10 determines that the user has designated the operation of the driving support function based on the pressing signal (including pressing position information) sent from CID3, and transmits an operation request signal for the driving support function to another ECU that controls the driving support function. The other ECU executes driving support control based on the reception of the operation request signal.
[0040] In this embodiment, the driving assistance control is, for example, a control related to a parking assist function, a control related to a collision damage mitigation function, a control related to a forward vehicle following function, etc. The CPU 10a of the integrated cockpit ECU 10 and other ECUs can exchange information with each other through CAN communication.
[0041] On the other hand, when the user presses the display area of the driving support function OFF button (the "SCM" OFF button) displayed on the home screen of CID3, the CPU 10a of the integrated cockpit ECU 10 determines that the user has designated deactivation of the driving support function based on the pressing signal (including pressing position information) sent from CID3, and transmits a deactivation request signal for the driving support function to another ECU that controls the driving support function. Based on the reception of the deactivation request signal, the other ECU does not implement the driving support function.
[0042] The ON / OFF button for the vehicle stability control (VSC) and the idle stop function are also displayed on the home screen of CID3. Similarly, when the user presses these display areas, other ECUs responsible for those functions will receive an activation request signal or a deactivation request signal and either activate or deactivate the function.
[0043] (Control of the meter display screen) Regarding the meter display 4, the CPU 10a of the integrated cockpit ECU 10 determines whether the backup fuse 20a of the backup power line L1 of the CID 3 is inserted or removed, and changes the display content or adds it to the display screen.
[0044] (If a backup fuse is installed) For example, when the CPU 10a of the integrated cockpit ECU 10 determines that the backup fuse 20a of the backup power line L1 of the CID 3 is inserted, it determines the currently set ON / OFF state of the illumination function and the currently set volume level as the display contents of the meter display 4. At this time, the CPU 10a of the integrated cockpit ECU 10 selects image data corresponding to the determined display contents from the memory 10b and displays them on the meter display 4.
[0045] Whether the backup fuse 20a of the backup power line L1 of CID3 is inserted or removed can be determined, for example, by detecting the voltage level of the power terminal connected to the backup power line L1 of CID3.
[0046] The set ON / OFF state of the illumination function and the set volume level are stored, for example, in a predetermined storage area of the memory 10b, and are displayed based on the stored contents of the storage area. The ON / OFF state of the illumination function is changed by pressing the ON / OFF switch of the illumination function on the steering switch 5. For example, when the ON switch of the illumination function on the steering switch 5 is pressed while the illumination function is in the OFF state, the signal is input to the CPU 10a of the integrated cockpit ECU 10. When the signal is input, the CPU 10a of the integrated cockpit ECU 10 rewrites the stored contents of the storage area for the ON / OFF state of the illumination function stored in the memory 10b to the ON state, and reflects this in the display of the meter display 4.
[0047] (If the backup fuse is removed) When the CPU 10a of the integrated cockpit ECU 10 determines that the backup fuse 20a of the backup power line L1 of the CID 3 is pulled out, it determines the setting screen for ON / OFF of the vehicle stability control function (VSC function), ON / OFF of the driving support function, and ON / OFF of the idling stop function as the display contents of the meter display 4. At this time, the CPU 10a of the integrated cockpit ECU 10 selects image data corresponding to the determined display contents from the memory 10b and displays it on the meter display 4.
[0048] The setting screens for turning on / off the vehicle stability control function (VSC function), the driving support function, and the idling stop function should normally be displayed on CID 3. However, if the backup fuse 20a in the backup power line L1 of CID 3 is removed, no power is supplied even if the ignition switch is turned on, and therefore these cannot be displayed on CID 3. Therefore, in this embodiment, these are displayed on the meter display 4.
[0049] As an example of the display mode of the setting screen, for example, a field for a vehicle skid prevention function (VSC function), a field for a driving support function (SCM function), and a field for an idling stop function (IS function) are displayed on the display screen of the meter display 4, and a cursor for designating one of them is displayed. The cursor is moved by pressing an item designation cursor movement switch on the steering switch 5. Here, every time the enter switch on the steering switch 5 is pressed, the function corresponding to the field where the cursor is located is switched between ON and OFF, and the CPU 10a of the integrated cockpit ECU 10 controls the display screen so that the changed ON / OFF state is reflected on the display screen.
[0050] Furthermore, when an operation to change the ON / OFF state of a function is performed, the CPU 10a of the integrated cockpit ECU 10 transmits a request signal (activation request signal / non-activation request signal) indicating the specified state to the ECU in charge.
[0051] Note that the display manner of the setting screen described above is one example, and as long as the vehicle stability control function (VSC function), driving assistance function (SCM function), and idling stop function (IS function) can be set on the meter display 4, they can be modified or added as appropriate.
[0052] Next, changes in the display screen of the meter display 4 and CID3 depending on the insertion / removal state of the backup fuse 20a will be described with reference to Fig. 2. Note that the display screen of CID3 in Fig. 2 shows some of the display items, and other display items are omitted.
[0053] During normal daily use, the backup fuse 20a in the backup power line L1 of the CID 3, the ACC fuse 20b in the ACC power line L2, the backup fuse 30a in the backup power line L3 of the meter display 4, the IG fuse 30b in the IG power line L4, and the ACC fuse 30c in the ACC power line L5 are all in an inserted state in the vehicle 1.
[0054] In this state, for example, when the ignition switch is turned ON, the meter display 4 displays the state of the illumination function that has been set (in FIG. 2, it shows "Illumination ON") and the set volume level (in FIG. 2, it shows "Volume 3").
[0055] Since the backup fuse 30a is inserted, driving power is supplied to the meter display 4 even when the ignition switch and the ACC power switch are OFF. However, when the ignition switch and the ACC power switch are OFF, the CPU 10a of the integrated cockpit ECU 10 controls the display screen so that the meter display 4 is not displayed.
[0056] On the other hand, in CID3, when the ignition switch is turned ON with all fuses 20a, 20b, 30a, 30b, and 30c inserted, a home screen including setting switches for various functions (such as vehicle stability control (VSC) and driving support function (SCM)) is displayed. Power at this time is supplied from the backup power line L1.
[0057] Since the backup fuse 20a is inserted, driving power is supplied to CID3 even when the ACC power switch is OFF. However, when the ignition switch is OFF or the ACC power switch is OFF, the CPU 10a of the integrated cockpit ECU 10 controls the display screen so that CID3 is not displayed.
[0058] When the vehicle 1 is transported or stored for a long period of time, leaving the backup power supply line L1 and the backup power supply line L3 conductive causes constant consumption of standby current (dark current), which may deteriorate the battery 2. Therefore, in such a case, the backup fuse 20a of the CID 3 and the backup fuse 30a of the meter display 4 are generally removed.
[0059] With the backup fuses 20a and 30a removed, for example, if the vehicle 1 needs to be moved while being transported, the ignition switch is set to the ON state and a drive source such as an engine is started. In this case, the meter display 4 is able to display information by the supply of power from the IG power line L4. However, since the CPU 10a of the integrated cockpit ECU 10 has determined that the backup fuse 20a of CID3 has been removed, the display contents of the meter display 4 are changed from the display of the illumination function setting state and the set volume to a setting screen for various functions (such as a vehicle stability control function (VSC) and a driving support function (SCM)) or are added to the display screen. As a result, even if the backup fuse 20a of CID3 has been removed, the settings of various functions (such as a vehicle stability control function (VSC) and a driving support function (SCM)) can be changed from the meter display 4 side.
[0060] On the other hand, in CID3, even if the ignition switch is set to the ON state with the backup fuses 20a and 30a removed, none of the power lines L1 and L2 are conductive, and therefore no display can be displayed on the display screen of CID3.
[0061] Assume that the backup fuses 20a, 30a are reinserted after transportation or long-term storage of the vehicle 1. When the ignition switch is set to the ON state in this state, the CPU 10a of the integrated cockpit ECU 10 determines that the backup fuse 20a of the CID 3 is inserted, and returns the display contents of the meter display 4 to the ON / OFF state of the illumination function that has been set and the volume level that has been set.
[0062] On the other hand, in CID3, when the ignition switch is set to the ON state with the backup fuses 20a, 30a reinserted, the display is resumed by the supply of power from the backup power line L1. At this time, the CPU 10a of the integrated cockpit ECU 10 controls so that a home screen including setting switches for various functions (such as the vehicle stability control (VSC) and driving support function (SCM)) is displayed on the display screen of CID3. This makes it possible to change the settings of various functions (such as the vehicle stability control (VSC) and driving support function (SCM)) or add them to the display screen from the display screen of CID3.
[0063] Therefore, according to the embodiment described above, since the meter display 4 is configured as a non-touch panel type display device, the display contents of the meter display 4 are changed and the setting operation is performed by operating the steering switch 5. If the setting screens of various functions (such as the vehicle stability control function (VSC) and the driving support function (SCM)) were to be displayed on the meter display 4, the number of times the steering switch 5 would be pressed would increase and the operability would deteriorate due to the deep hierarchical structure of the display screen. Therefore, in this embodiment, a touch panel type CID 3 is provided and the setting screens of various functions (such as the vehicle stability control function (VSC) and the driving support function (SCM)) are displayed on the CID 3, thereby preventing the number of times the steering switch 5 would be pressed and preventing the display screen from becoming too deep.
[0064] However, according to the configuration of this embodiment, if the backup fuse 20a of CID 3 is removed to eliminate standby current (dark current), power cannot be supplied to CID 3, and it may become impossible to set various functions (such as vehicle stability control (VSC) and driving support function (SCM)) that may be required during temporary movement during transportation. One way to avoid this is to provide a separate IG power line on the CID 3 side so that when the ignition switch is set to the ON state, power is supplied and a display can be performed. However, this requires the formation of a separate IG power circuit and a harness, which increases the mass of the vehicle 1 and increases costs.
[0065] Therefore, in this embodiment, when the backup fuse 20a is removed during transportation or long-term storage and display is not possible on the CID 3 side, the display content of the meter display 4 is changed so that a setting screen for various functions (such as vehicle stability control (VSC) and driving support function (SCM)) is displayed on the meter display 4 side where the IG power line L4 is provided. This prevents consumption of standby current during transportation or long-term storage, while allowing settings to be changed on the meter display 4 side when a situation arises in which settings for various functions (such as vehicle stability control (VSC) and driving support function (SCM)) are required, such as when the vehicle needs to be moved temporarily, improving convenience. This also eliminates the need to form a separate IG power circuit or prepare a harness, reducing increases in weight and cost of the vehicle 1.
[0066] During transportation or long-term storage of the vehicle 1, there is little need to display the ON / OFF state of the illumination function or the set volume, so changing the display content of the meter display 4 has little impact on convenience.
[0067] The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention. For example, in the above-described embodiment, two display devices (CID 3, meter display 4) are provided, and when the backup fuse 20a of CID 3 is removed, part of the contents displayed on CID 3 (setting switches for various functions (such as vehicle stability control (VSC) and driving support function (SCM))) are displayed on the display screen of the meter display 4. However, it is also possible to provide one display device, and change or add display contents to the display screen depending on the insertion / removal state of the backup fuse of that display device. In this case, the display contents of the display device can be changed or added depending on the situation, improving convenience.
[0068] In addition, when the backup fuse 20a is removed, the content to be displayed on the meter display 4 (the content displayed on CID 3) can be changed or added to as necessary. For example, if a window opening / closing switch or the like is displayed on CID 3, that switch may be displayed.
[0069] Backup fuse 20a of backup power line L1 of CID 3 and backup fuse 30a of backup power line L3 of meter display 4 may be the same fuse. Similarly, ACC fuse 20b of ACC power line L2 and ACC fuse 30c of ACC power line L5 may be the same fuse.
[0070] Furthermore, the ACC power line L2 may be omitted from the power lines of CID 3. Furthermore, the ACC power line L5 may also be omitted.
