FIG. 1 is a schematic configuration block diagram of an in-vehicle electronic device according to an embodiment.
The in-vehicle electronic device 10 is roughly divided into an electronic device main body 11 to which power is supplied from an in-vehicle battery B via an accessory switch (ACC switch), and various operators including operation buttons. And a detachable operation panel (DCP) 12 configured to be detachable.

FIG. 2 is an external perspective view of the in-vehicle electronic device in a state where the detachable operation panel is not attached.
FIG. 3 is a rear perspective view of the detachable operation panel.
The electronic device body 11 includes a power switch 21 that is electrically connected to the accessory switch, a system controller 22 that controls the vehicle-mounted electronic device 10 as a whole, and a detachable operation panel 12 attached to the electronic device body 11. The panel attachment / detachment detection switch 23 for detecting this and a pair of LED illumination devices 24A and 24B constituting the illumination device are provided.

In this case, the LED lighting devices 24A and 24B perform guide illumination for guiding the mounting position of the detachable operation panel 12 only for a predetermined time after the power is turned on when the detachable operation panel 12 is not mounted. When the mold operation panel 12 is mounted, illumination of an operator such as an operation button or display illumination is performed via a light guide member 12A having an end provided on the side surface of the detachable operation panel 12.
Operators 26A to 26G are provided on the front surface side of the detachable operation panel 12, and a panel attachment / detachment detection protrusion 27 is provided on the rear surface.

  In this case, in the detachable operation panel 12, an operation protrusion (not shown) protrudes from the back surface of the detachable operation panel 12 by a mechanical mechanism when the operation elements 26 </ b> A to 26 </ b> G are pressed. It is configured. An electrical switch (not shown) is pressed on the back side of the front panel of the electronic device main body 11 facing the detachable operation panel 12 of the electronic device main body 11 by an operation protrusion protruding from the detachable operation panel 12. However, the operation projecting piece is provided so as to be able to contact through a hole formed in the surface panel of the electronic device main body 11. As a result, the system controller 22 of the electronic device main body 11 detects the operation state of the user based on the on / off state of the electrical switch. By adopting such a configuration, it is not necessary to provide a circuit board, a connector, or the like on the detachable operation panel 12 side, and even if the detachable operation panel 12 is dropped or handled somewhat roughly, contact failure, etc. Therefore, it is easy to handle.

FIG. 4 shows a block diagram of a control system of the electronic device main body.
The system controller 22 includes a ROM 31 that stores a control program in advance, a RAM 32 that temporarily stores data, and an MPU 33 that controls the entire vehicle-mounted electronic device based on the control program. Here, the ROM 31, RAM 32 and MPU 33 constitute a microcomputer.
Further, the system controller 22 is connected to the power switch 21 and the panel attachment / detachment detection switch 23, and performs an interface operation between them, and an illumination drive unit 35 for driving the LED illumination devices 24A and 24B. It is equipped with.

FIG. 5 is a cross-sectional view of the main part of the in-vehicle electronic device 10.
As shown in FIG. 5, the light guide member 12 </ b> A is disposed on the back side of the operators 26 </ b> A to 26 </ b> G of the detachable operation panel 12.
The LED 24A1 constituting the LED illumination device 24A and the LED 24B1 constituting the LED illumination device 24B are arranged on the end surface in the left-right direction of the light guide member 12 so that the illumination light is emitted from the LEDs 24A1 and 24B1. Then, illumination light will be guide | induced to the light guide member 12, and will irradiate operation elements 26A-26G from a back surface.

Next, the operation of the embodiment will be described.
FIG. 6 is a processing flowchart of the embodiment.
First, the MPU 33 of the system controller 22 determines whether or not the power switch 21 is turned on via the interface unit 34 (step S1). If it is determined at step S1 that the power source 21 is not turned on, a standby state is entered.
If the power switch 21 is turned on in step S1, it is determined whether or not the detachable operation panel 12 is mounted via the interface unit 34 (step S2). Specifically, due to the attachment of the detachable operation panel 12, the panel attachment / detachment detection protrusion 27 is detected on the rear surface of the detachable operation panel 12 to detect that the panel attachment / detachment detection switch 23 is turned on. Then, the MPU 33 determines that the detachable operation panel 12 is attached.

If it is determined in step S2 that the operation panel is mounted (step S2; Y), the controller controls the illumination device to illuminate the operation panel with normal brightness during operation (step S3).
Then, the controller determines whether or not the operation panel has been removed (step S4).
If it is determined in step S4 that the panel has not been removed (step S4; N), the controller determines whether the power is turned off (step S5).

If it is determined in step S5 that the power is not turned off (step S5; N), the process proceeds to step S3, and illumination is continued.
In step S5, when the power is turned off (step S5; Y), the controller controls the lighting device, turns off the lighting (step S10), and ends the process.
On the other hand, if it is determined in step S4 that the panel has been removed (step S4; Y), the controller controls the illumination device, turns off the illumination (step S10), shifts the process to step S1, and waits. It becomes a state.

In step S2, if the operation panel is not mounted (step S2; N), the controller starts a timer (step S6) and controls the illumination device to guide the operation panel mounting position. Illumination of the operation panel mounting scheduled position is performed with a lower brightness than that of the normal brightness at the time of operation (step S7).
Subsequently, the controller determines whether or not the timer has counted up (step S8).
If the timer counts up in the determination in step S8, the controller controls the lighting device to turn off the useless power consumption, turns off the lighting (step S10), and shifts the processing to step S1. It will be in a standby state.

If it is determined in step S8 that the timer has not yet counted up (step S8; No), the controller determines whether or not the operation panel is mounted by the user (step S9).
If it is determined in step S9 that the operation panel is mounted by the user (step S9; Y), the controller moves the process to step S3 and illuminates the operation panel with normal brightness during operation (step S9). S3) Thereafter, the processing is continued in the same manner.
On the other hand, if it is determined in step S9 that the operation panel is not yet mounted, the controller shifts the process to step S8 again.

  As described above, according to the present embodiment, when the detachable operation panel 12 is not attached for a predetermined period after the power is turned on, the operator of the detachable operation panel 12 is illuminated. Therefore, the user can recognize the mounting position of the detachable operation panel 12 without turning on the room light or the like because the LED lighting devices 24A and 24B can provide illumination for guiding the mounting position of the detachable operation panel 12. It becomes possible.

  In the above description, the luminance is changed between when the detachable operation panel 12 is mounted and when it is not mounted. However, in addition to the luminance, an illumination pattern (such as a blinking pattern or an illumination color pattern in the case of a full-color LED) It is also possible to change the configuration.

  In the above description, the case where the control program is stored in the ROM in advance has been described. However, the control program is recorded in advance on recording media such as various magnetic disks, optical disks, and memory cards, and read from these recording media. It can also be configured to be installed. It is also possible to provide a communication interface and download the control program via a network such as the Internet or LAN, and install and execute the program. With such a configuration, it is possible to configure a higher-function in software or a more reliable in-vehicle electronic device.
