  In the future, there is a high possibility that the operation system of the vehicle is integrated into a common interface, and it is assumed that the operation unit and the mirror adjustment switch of the car navigation system described above are integrated into one interface. As an example of this, there is an example in which a touch panel of a car navigation system is used as an interface of a car navigation system and an exterior door mirror, for example.

  However, in the future, there is a possibility that not only the car navigation system and the outside door mirror but also the window glass opening / closing, rearview mirror adjustment, meter display, and the like will be integrated. If this happens, the touch panel of the car navigation system is likely to be unable to cope with the limitations of the screen size and operation mode. In addition, depending on the device to be operated, there is a case where it is difficult to obtain an intuitive operation by a touch operation on the touch panel, and there is a concern that operability may be deteriorated.

  An object of the present invention is to provide a wireless interface device and an electronic key that can aggregate interfaces of devices provided for communication targets and can secure operability suitable for each device.

  According to this configuration, since the electronic key can be used as the operation terminal for the selection screen, it is not necessary to prepare an operation terminal separately, and the number of parts can be reduced. In addition, when a plurality of communication target devices are integrated into one interface, an operation mode in which a selection screen corresponding to the interface is displayed on the communication terminal and the selection screen is selected or determined with an electronic key is used. Therefore, there is no problem even if many devices are operated on one selection screen. Further, since the selection screen can be operated by a natural operation such as tilting or shaking the electronic key, the screen can be operated by an intuitive operation.

The gist of the present invention is that when the electronic key is moved as an operation terminal, the designated coordinate position moves on the selection screen.

The gist of the present invention is that communication of the transmission means uses communication of a different system from the ID verification performed by the electronic key with the communication target.
According to this configuration, since communication of a different system from ID verification is performed, communication between ID verification and screen operation does not overlap. Therefore, since it is difficult for interference to occur, it is possible to ensure the establishment of each communication.

The gist of the present invention is that the electronic key is provided with a determination operation means that is operated when a determination operation is performed on the selection screen.
According to this configuration, since the operation means for determining the selection screen is provided, for example, the operation from the coordinate selection to the determination is performed in a natural operation mode in which the electronic key is shaken and then the determination operation means is operated. It becomes possible.

According to this configuration, the operation mode of the electronic key can be switched to the dedicated mode of the operation terminal, so that the electronic key can be used properly from time to time.

  In the present invention, the selection screen is displayed as a screen when operating the communication target device on the display means provided in the communication target, and the electronic unit used when selecting or determining the designated coordinate position of the selection screen. A detecting means for detecting an operation amount when the electronic key is moved as an operation terminal of the selection screen, and a transmitting means for wirelessly transmitting a detection value of the detecting means as an operation signal to the communication target When the communication target receives the operation signal, it is determined by the communication target what operation the operation signal corresponds to on the selection screen, and the operation is reflected on the selection screen. Is the gist.

The electronic key system 3 includes a key operation free system that executes ID collation using communication from the vehicle 1 side as a trigger, and a wireless key system that executes ID collation using communication from the electronic key 2 side as a trigger. Note that the vehicle 1 corresponds to a communication target.

  In this case, the vehicle 1 is provided with an ID verification device 4, a door lock device 5, and an engine starting device 6, which are connected via a bus 7 in the vehicle. The ID verification device 4 is provided with a verification ECU 8 as a control unit of the ID verification device 4. The ID code of the electronic key 2 is registered in the memory (not shown) of the verification ECU 8. The verification ECU 8 receives an out-of-vehicle transmitter 9 capable of transmitting LF (Low Frequency) band radio waves outside the vehicle, an in-vehicle transmitter 10 capable of transmitting LF radio waves into the car, and UHF (Ultra High Frequency) band radio waves. A possible vehicle tuner 11 is connected.

  The electronic key 2 is provided with a key control unit 12 that manages the operation of the electronic key 2. The ID code of the electronic key 2 is registered in the memory (not shown) of the key control unit 12. Connected to the key control unit 12 are an LF receiver 13 capable of receiving LF radio waves and a UHF transmitter 14 capable of transmitting UHF radio waves. A battery 15 is mounted on the electronic key 2 as a power source for the electronic key 2.

  When the electronic key 2 is located outside the vehicle, the vehicle outside transmitter 9 intermittently transmits a request signal Srq outside the vehicle as an ID reply request. When the electronic key 2 enters the communication area of the request signal Srq, the electronic key 2 is activated from the standby state and transmits the ID signal Sid to the vehicle 1. When ID verification, so-called vehicle exterior verification, is established between the electronic key 2 outside the vehicle and the vehicle 1, door lock locking / unlocking of the vehicle door by the door lock device 5 is permitted or executed.

  When the user's boarding is detected by a courtesy switch (not shown) of the vehicle 1, for example, a request signal Srq is transmitted from the in-vehicle transmitter 10 instead of the out-of-vehicle transmitter 9. When ID verification, so-called in-vehicle verification, is established between the electronic key 2 in the vehicle and the vehicle 1, engine start operation by the engine switch 16 is permitted.

  The electronic key 2 is provided with an operation button (hereinafter referred to as a wireless operation button) 17 for wireless communication. The wireless operation button 17 includes, for example, a locking / unlocking button that is operated when the door lock of the vehicle 1 is locked / unlocked. When the wireless operation button 17 is operated with the electronic key 2, the wireless signal Swl is transmitted from the electronic key 2. The wireless signal Swl includes an ID code and a function code of the wireless operation button 17. When the vehicle tuner 11 receives the wireless signal Swl, the verification ECU 8 executes ID verification (wireless verification). When the verification is established, the verification ECU 8 causes the door lock device 5 to execute door lock / unlock.

  The wireless operation button 17 includes, for example, a power slide door opening / closing, a tailgate opening / closing, a trunk opening / closing, and a window glass opening / closing in addition to door locking / unlocking / unlocking. Of course, other types may be adopted.

  Further, the vehicle 1 and the electronic key 2 are electronic keys as operation terminals for selecting or designating a designated coordinate position 20 (illustrated by a cursor in this example) on a selection screen 19 (see FIG. 2) displayed on the display 18 in the vehicle. 2 is used. That is, the electronic key 2 of this example is used not only for the key function of the vehicle 1 but also for selecting the coordinate position of the selection screen 19 displayed on the display 18 or designating one coordinate on the selection screen 19. It can also be used as an operating terminal for operating. The display 18 corresponds to display means.

  As shown in FIG. 2, for example, a display of a car navigation system is used as the display 18, and the display 18 is arranged in a center cluster of the vehicle, for example. The display operation of the display 18 is controlled by a display control ECU 22 (see FIG. 1) that is a control unit for screen display control. The display 18 corresponds to display means.

  On the selection screen 19, for example, operations such as a car navigation system, a door mirror outside the vehicle, a window glass, and a rearview mirror are possible. In this case, a plurality of selection items 23, 23... Corresponding to each function are displayed on the selection screen 19, and each function is operated by selecting and specifying one of these selection items 23, 23. Let The selection state of the selection items 23, 23... May be either overlapping the screen cursor or activating the selection item 23 itself.

  As shown in FIG. 1, the electronic key 2 is provided with a motion sensor 24 that detects the movement of the electronic key 2. As the motion sensor 24, for example, an inclination sensor, a vibration sensor, an acceleration sensor, an angular velocity sensor, a load sensor, or the like is used. The motion sensor 24 of this example detects the movement direction of the electronic key 2 in three dimensions in the XYZ directions, and outputs the movement direction and the movement amount to the key control unit 12 as detection signals. Note that the motion sensor 24 corresponds to detection means.

  As shown in FIGS. 1, 3, and 4, the electronic key 2 is provided with a determination operation button 25 that is operated when a selection item 23 is designated on the selection screen 19. For example, a momentary type push button is used as the determination operation button 25, and a pair of determination operation buttons 25 are provided side by side in the width direction (left-right direction) of the electronic key 2. Of the single determination operation buttons 25, 25 in this example, the left button corresponds to the left click button, and the right button corresponds to the right click button. The determination operation button 25 corresponds to a determination operation unit.

  As shown in FIG. 1, the electronic key 2 is equipped with a Bluetooth communication device 26 capable of wireless communication by Bluetooth (registered trademark). Bluetooth is a kind of short-range wireless communication technology used for connection between devices of about several meters, for example. Bluetooth has an advantage that, for example, radio waves in the 2.45 GHz band are used, and communication can be established if there is an obstacle between devices as long as the distance is about 10 m. Further, there is an advantage that power consumption can be reduced as compared with infrared communication such as IrDA (Infrared Data Association). The Bluetooth communication device 26 constitutes a communication means.

  The key control unit 12 is provided with a key operation notification unit 27 that notifies the vehicle 1 of the movement of the electronic key 2 applied to the electronic key 2. The key operation notifying unit 27 determines the movement of the electronic key 2 based on the detection signal of the motion sensor 24 and transmits a key operation signal Ssr corresponding to the determination result to the vehicle 1 via the Bluetooth communication device 26. The key operation signal Ssr includes data on the three-dimensional movement direction and the movement amount of the electronic key 2. Further, when detecting that the determination operation button 25 has been operated, the key operation notification unit 27 transmits a determination signal Sen notifying that to the vehicle 1 via the Bluetooth communication device 26. Note that the key operation notification unit 27 constitutes a communication means, and the key operation signal Ssr and the determination signal Sen constitute an operation signal.

  As shown in FIG. 4A, in the electronic key 2 of this example, the operation direction of the electronic key 2 is the side where the determination operation button 25 is directed forward. This operation direction is detected by the motion sensor 24. As shown in FIG. 4B, if the width direction of the electronic key 2 when the determination operation button 25 is directed forward is the X axis and the thickness direction of the electronic key 2 is the Y axis, this X− The Y axis corresponds to the XY axis of the display 18.

  As shown in FIG. 1, the key control unit 12 is provided with a mode switching unit 28 that enables a mode in which the electronic key 2 is used as an operation terminal of the display 18, a so-called terminal operation mode. In the case of this example, turning the decision operation button 25 forward in the electronic key 2 and receiving the in-vehicle verification establishment notification Sok from the vehicle 1 are the conditions for using the electronic key 2 as an operation terminal. The mode switching unit 28 corresponds to mode switching means.

  The electronic key 2 is provided with a notification unit 29 that notifies the operator of transmission of the key operation signal Ssr. The notification unit 29 is formed of, for example, an LED, and is lit (flashes) for a predetermined time when the transmission of the key operation signal Ssr is completed. The electronic key 2 is provided with a display 30 made of, for example, a liquid crystal screen. For example, a message indicating completion of transmission of the key operation signal Ssr may be displayed on the display 30.

  The vehicle 1 is provided with a Bluetooth communication device 31 on the vehicle 1 side that communicates with the Bluetooth communication device 26 of the electronic key 2. The Bluetooth communication device 31 is connected to the display control ECU 22 of the display 18. When receiving the key operation signal Ssr from the electronic key 2, the Bluetooth communication device 31 outputs the key operation signal Ssr to the display control ECU 22.

  The display control ECU 22 is provided with a screen processing unit 32 that reflects the screen operation of the selection screen 19 executed by the electronic key 2 on the selection screen 19. Based on the key operation signal Ssr received by the Bluetooth communication device 31, the screen processing unit 32 executes the movement of the designated coordinate position 20 on the selection screen 19 and the determination operation of one specific coordinate on the selection screen 19. The screen processing unit 32 corresponds to a processing unit.

Next, the operation of the wireless interface device 21 of this example will be described with reference to FIGS.
When the verification ECU 8 confirms that the in-vehicle verification is established, the verification ECU 8 transmits an in-vehicle verification establishment notification Sok from the in-vehicle transmitter 10. If the electronic key 2 is in the communication area of the in-car transmitter 10, the in-car collation establishment notification Sok is received by the LF receiver 13.

  Further, when the electronic key 2 is used as an operation terminal of the display 18, as shown in FIG. 4, the electronic key 2 is inverted in the front-rear direction and the determination operation button 25 is directed forward. In the mode switching unit 28, the electronic key 2 receives the determination operation button 25 of the electronic key 2 directed forward based on the detection signal from the motion sensor 24 and the in-vehicle verification establishment notification Sok from the vehicle 1. The terminal operation mode is enabled on the condition that Thereby, the electronic key 2 can be used as an operation terminal of the display 18.

  At this time, the user who possesses the electronic key 2 swings the electronic key 2 in that direction so that the designated coordinate position 20 on the selection screen 19 is positioned at the selection item 23 to be executed. For example, when it is desired to move the designated coordinate position greatly to the lower right, as shown in FIG. 5 (a), the electronic key 2 is greatly swung to the lower right, and when the designated coordinate position 20 is to be slightly moved to the upper left, As shown in FIG. 5B, the electronic key 2 is shaken slightly to the upper left. When the electronic key 2 is swung, the motion sensor 24 detects this movement and outputs a detection signal to the key operation notification unit 27.

  The key operation notification unit 27 transmits a key operation signal Ssr corresponding to the detection signal of the motion sensor 24 from the Bluetooth communication device 26. The key operation signal Ssr includes the three-dimensional movement direction and the movement amount of the electronic key 2.

  When the Bluetooth communication device 31 receives the key operation signal Ssr, the screen processing unit 32 changes the designated coordinate position 20 based on the key operation signal Ssr. That is, the screen processing unit 32 grasps the movement amount and movement direction of the electronic key 2 from the data included in the key operation signal Ssr, and positions the designated coordinate position 20 at the corresponding coordinate position. For example, when the electronic key 2 is swung to the lower right as shown in FIG. 5A, the designated coordinate position 20 moves greatly to the lower right of the screen. On the other hand, when the electronic key 2 is operated to the lower left as shown in FIG. 5B, the designated coordinate position 20 slightly moves to the upper left of the screen.

  As described above, after the electronic key 2 is swung to place the designated coordinate position 20 at the desired selection item 23, the determination operation button 25 is pressed as shown in FIG. 5C. Then, the key operation notifying unit 27 transmits a determination signal Sen from the Bluetooth communication device 26.

  When the Bluetooth communication device 31 receives the determination signal Sen, the screen processing unit 32 determines the selection item 23 that is currently selected by using the determination signal Sen as a trigger. That is, the screen processing unit 32 recognizes that the selection item 23 in the selected state is designated, and outputs that fact to another ECU. For this reason, the operation | movement of the apparatus according to the selection item 23 is performed.

  As described above, in this example, the motion sensor 24 is mounted on the electronic key 2, the movement applied to the electronic key 2 is detected by the motion sensor 24, and the electronic key 2 can be used as an operation terminal of the display 18. Therefore, the selection items 23 for operating various in-vehicle devices are displayed on the display 18, and these selection items 23 can be selected by an operation of moving the electronic key 2. For this reason, since the screen of the display 18 can be operated with the electronic key 2 as if it were a mouse of a personal computer, a large number of in-vehicle devices can be operated by an intuitive operation of shaking the electronic key 2.
