A vehicle-mounted information acquisition system including a vehicle-mounted remote controller according to a first embodiment of the present invention will be described with reference to the drawings. In the following description, an example of using an ETC device as an on-board device is shown, but the present application can be applied to other on-board devices that acquire information from a roadside device by wireless communication, such as a DSRC device (DSRC on-board device). Inventive configurations can be applied.

FIG. 1 is a configuration diagram of an in-vehicle information acquisition system including an in-vehicle remote controller according to a first embodiment of the present invention. FIG. 2 is a diagram showing a state in which an in-vehicle information acquisition system including an in-vehicle remote controller according to the first embodiment of the present invention is installed in a vehicle.

As shown in FIG. 1, the information acquisition system 10 includes a vehicle-mounted device 20 and a vehicle-mounted remote controller 30 . An antenna 201 for the vehicle-mounted device is connected to the vehicle-mounted device 20 via a wiring cable 202 .

As shown in FIG. 2, the vehicle-mounted device 20 is installed in a location that is difficult to see from the outside, such as inside or behind a dashboard 901 of the vehicle 90 . This is to prevent the vehicle-mounted device 20 from being stolen, for example. Antenna 201 is installed at the upper end of the windshield of vehicle 90 .

The in-vehicle remote controller 30 is placed near a user such as a driver. For example, as shown in FIG. 2, the in-vehicle remote control device 30 is placed on the surface of the portion of the front console 902 that is arranged between the seats.

As shown in FIG. 1 , the vehicle-mounted device 20 includes an ETC control section 21 and a main body communication section 22 . The ETC control section 21 and the main body communication section 22 are connected.

ETC control unit 21 is connected to antenna 201 . The ETC control unit 21 performs two-way wireless communication with the roadside device via the antenna 201 . The ETC control unit 21 acquires information about ETC from the roadside device. In addition, the ETC control unit 21 executes various processes related to the ETC system, such as toll settlement, through wireless communication with the roadside device.

The body communication unit 22 communicates with the remote control communication unit 32 of the in-vehicle remote control device 30 . Communication executed between the ETC control unit 21 and the remote control communication unit 32 is, for example, short-range communication such as wireless communication using radio waves in the 2.4 GHz band or infrared communication.

The body communication unit 22 receives the remote control information transmitted from the remote control communication unit 32 and outputs it to the ETC control unit 21 . Further, the body communication section 22 transmits information acquired from the ETC control section 21 to the remote control communication section 32 .

The in-vehicle remote control device 30 includes a remote control section 31 , a remote control communication section 32 , a storage section 33 , an operation section 34 , a speaker 35 and a display section 36 .

The remote controller 31 performs overall control of the in-vehicle remote controller 30 . The remote control unit 31 executes a function according to an operation performed on the operation unit 34 by the user. Function programs executed by the remote controller control unit 31 are stored in the storage unit 33 . The remote controller 31 executes various functions by reading function programs from the storage unit 33 and executing them.

The remote control unit 31 performs remote operation control of the vehicle-mounted device 20 via the remote control communication unit 32 . The remote controller 31 acquires information from the vehicle-mounted device 20 via the remote controller 32 .

The remote controller 31 performs sound emission control on the speaker 35 . Although specific processing will be described later, the remote control unit 31 converts the information acquired from the vehicle-mounted device 20 and the contents of the functions assigned to the operators of the operation unit 34 into voice, and emits sound from the speaker 35. . With this configuration, the information acquired from the vehicle-mounted device 20 and the contents of the functions assigned to the operators of the operation unit 34 can be provided to the user by sound from the vehicle-mounted remote controller 30 . Thereby, the user can grasp the information acquired from the vehicle-mounted device 20 regardless of whether the user is driving or stopped. Also, the user can reliably operate the operation unit 34 to obtain desired information.

The remote control unit 31 performs image display control on the display unit 36 . The remote control unit 31 converts the information acquired from the vehicle-mounted device 20 and the functions assigned to the operators of the operation unit 34 into image data, and displays the image data on the display unit 36 . Thereby, the user can grasp the information acquired from the vehicle-mounted device 20 with an image. Also, the user can reliably operate the operation unit 34 to obtain desired information. Note that the display unit 36 can be omitted.

FIG. 3 is a plan view showing one aspect of the external shape of the in-vehicle remote control device 30 according to the first embodiment of the present invention.

The in-vehicle remote control device 30 includes a rectangular parallelepiped housing 300 . A display panel constituting the display unit 36 is arranged on the front wall of the housing 300 . Furthermore, a plurality of operators (operation buttons) 341 , 342 , 343 , 344 , 345 , and 346 constituting the operation section 34 are arranged on the front wall of the housing 300 . In this embodiment, six operators are provided, but the number of operators may be appropriately determined according to the number of functions executed by the in-vehicle remote control device 30 .

As shown in FIG. 3, the plurality of operators 341-346 are each formed in a unique shape (corresponding to each operation function). At this time, as shown in FIG. 3, at least one of the plurality of manipulators 341-346 may have a shape different from that of the other manipulators. It is preferable that the plurality of operators 341-346 have different shapes for each assigned function. For example, as shown in FIG. 3, it is sufficient that almost all operators have different shapes, and more preferably all operators have different shapes.

In this way, by making the operators 341 to 346 have different shapes according to the assigned functions, the user can simply touch the operators 341 to 346 and operate the touched operators. It is possible to grasp the functions that can be executed. Thereby, the user can perform a desired operation input without looking at the in-vehicle remote control device 30 .

It should be noted that even if the external shape in front view is the same, as shown in FIG. 4, the structure of the manipulator may be changed. FIG. 4 is a diagram showing a cross-sectional structure of an operator of the in-vehicle remote controller according to the first embodiment of the present invention.

The manipulators 341 and 342 are arranged in the housing 300 so as to protrude from the housing 300 . A concave portion 3420 is provided on the tip surface of the projection of the manipulator 342 . By providing the recessed portion 3420 in the manipulator 342 in this way, even if the manipulator 342 and the manipulator 341 have the same external shape when viewed from the front, the surface shape of the protrusion that the user's finger touches differs. Therefore, the user can identify the manipulator 341 and the manipulator 342 without looking. Thereby, the user can reliably perform the operation input for obtaining the desired information.

The housing 300 contains an electronic circuit board that implements the remote controller 31 , the remote controller 32 , and the memory 33 , and the speaker 35 . For example, as shown in FIG. 3, the speaker 35 is built in the housing 300 with the front side of the housing 300 as the sound emission direction, and a plurality of holes are formed in the front wall area where the speaker 35 is arranged. is provided. As a result, the sound from the speaker 35 is efficiently emitted to the front side of the housing 300 . Note that the speaker 35 may be built in the housing 300 with the rear surface side of the housing 300 as the sound emitting direction.

Next, each process executed by the in-vehicle remote control device 30 according to the first embodiment of the present invention will be specifically described.

(1) Acceptance of Operation FIG. 5 is a diagram showing a processing flow of accepting an operation in the in-vehicle remote control device according to the first embodiment of the present invention.

When each operator 341 to 346 constituting the operation unit 34 is pushed, each operator 341 to 346 outputs a push detection signal to the remote controller control unit 31 . At this time, each operator 341-346 outputs a push detection signal each time it is pushed. In other words, if it is pushed once, it outputs a push-in detection signal once, and if it is pushed twice in a row, it outputs a push-in detection signal twice.

The remote controller control unit 31 receives an operation input of each operator 341 to 346 by detecting a depression detection signal (S101). The remote control unit 31 identifies the operator from which the depression detection signal is output (S102).

The remote controller control unit 31 waits for a predetermined time after the first depression detection signal is input, and checks whether the second depression detection signal is input. As a result, the remote control unit 31 detects the number of inputs (the number of clicks) of the depression detection signal (S103).

If the number of clicks is 1 (S104: YES), the remote control unit 31 executes guidance notification of the function assigned to the operator that is the output source of the input press detection signal (S105). This single click corresponds to the "first operation mode" of the present invention. That is, the remote controller control unit 31 emits sound from the speaker 35 about the contents of the function that can be executed by pressing the operator selected by the user. For example, when an operator to which service guidance is assigned, which will be described later, is pushed once, the remote control unit 31 emits a sound from the speaker 35 indicating that the service guidance is executed by pushing the operator. In this way, the user can confirm the function that can be executed by the pressed operation by providing the guidance of the function assigned to the operation by voice. This allows the user to reliably perform the operation for executing the desired function. Therefore, the user can reliably obtain the desired information.

If the number of clicks is not one (S104: NO) but two (S106: YES), the remote control unit 31 executes the function assigned to the operator that is the output source of the input depression detection signal. (S107). This double click corresponds to the "second operation mode" of the present invention. For example, the remote controller 31 executes the service guidance when the operator to which the service guidance is assigned is pushed twice. In this way, it is possible to make a mistake in executing a function desired by a user because the function is not executed by performing a simple but unique operation, rather than by performing a general and simple one-time push. can be done without fail. Therefore, the user can reliably obtain the desired information.

If the number of clicks is neither 1 (S104: NO) nor 2 (S106: NO), the remote controller 31 issues an error notification (108). For example, the remote control unit 31 emits a sound from the speaker 35 indicating that the detected pressing operation is invalid.

(2) Execution of Service Guidance FIG. 6 is a diagram showing a processing flow regarding service guidance in the in-vehicle remote controller according to the first embodiment of the present invention.

The remote control unit 31 identifies the operator from which the depression detection signal is output, and if the operator is for service guidance (S201: YES), detects the number of depressions (the number of clicks). When the remote control unit 31 detects that the operator is not for service guidance (S201: NO), the remote controller 31 executes another process corresponding to the pushed operator (S208).

When the remote control unit 31 detects that the number of clicks is 1 (S202: YES), the remote control unit 31 notifies that the service guidance will be executed by this operation and the outline of the service guidance by emitting sound from the speaker 35 ( S203). That is, the remote control unit 31 makes a preliminary notification of service guidance.

When the remote controller control unit 31 detects that the number of clicks is not one (S202: NO) but two (S204: YES), it executes service guidance.

Specifically, the remote controller 31 transmits a request signal for acquiring information on service guidance to the vehicle-mounted device 20 via the remote controller 32 . In response to this request signal, the remote controller 31 acquires information on service guidance from the vehicle-mounted device 20 (S205).

A service guide is, for example, a guide to general services provided by the ETC system, such as "Charge discounts are applied on the Akashi Kaikyo Bridge" and "The toll system has changed on the Hanshin Expressway." It is.

When the information about the service guidance is acquired, the remote controller control unit 31 converts the information into voice and emits sound from the speaker 35 (S206).

In this way, by notifying the service guidance by voice, the user can reliably obtain the service guidance regardless of whether the user is driving or stopped, that is, regardless of the user's state.

If the number of clicks is neither 1 nor 2 (S202: NO→S204: NO), the remote control unit 31 outputs an error notification indicating invalid operation input from the speaker 35 (S207). ). Thereby, the user can surely recognize that the operation input performed by the user is wrong.

(3) Execution of Fee Guidance FIG. 7 is a diagram showing a processing flow relating to fee guidance in the in-vehicle remote control device according to the first embodiment of the present invention.

The remote control unit 31 identifies the operator from which the push-in detection signal is output, and detects the number of pushes (the number of clicks) if the operator is for charge information (S301: YES). When the remote controller control unit 31 detects that the operator is not for fee guidance (S301: NO), it executes other processing corresponding to the pushed operator (S308).

When the remote control unit 31 detects that the number of clicks is 1 (S302: YES), the speaker 35 emits a sound to notify the execution of charge guidance and the outline of the charge guidance by this operation (S302: YES). S303). In other words, the remote control unit 31 makes a preliminary notification of fee guidance.

If the number of clicks is not once (S302: NO) but detected that the number of clicks is two (S304: YES), the remote controller control unit 31 executes fee guidance.

Specifically, the remote control unit 31 transmits a request signal for acquiring information on fee guidance to the vehicle-mounted device 20 via the remote control communication unit 32 . In response to this request signal, the remote controller control unit 31 acquires information on fee guidance from the vehicle-mounted device 20 (S305).

The toll guide is information about specific tolls provided by the ETC system, such as "The toll just now is XXXX yen.", "The toll for the current road is OOO yen."

When the remote controller control unit 31 acquires the information on the fee guide, it converts it into a voice and emits a sound from the speaker 35 (S306).

In this way, by giving voice notification of charge guidance, the user can reliably grasp the charge regardless of whether the user is driving or stopped, that is, regardless of the user's state.

If the number of clicks is neither 1 nor 2 (S202: NO→S204: NO), the remote control unit 31 outputs an error notification indicating invalid operation input from the speaker 35 (S207). ). Thereby, the user can surely recognize that the operation input performed by the user is wrong.

Note that a TTS (Text To Speech) function can also be used for the service guidance and fee guidance described above. In this case, the vehicle-mounted device 20 transmits service guide information and charge guide information to the vehicle-mounted remote controller 30 in the form of text data. The remote control unit 31 of the in-vehicle remote control device 30 applies the TSS function to the acquired text data, reads out the text data, and emits sound from the speaker 35 . By using such a configuration, it is not necessary to communicate raw audio data between the vehicle-mounted device 20 and the vehicle-mounted remote controller 30 . Therefore, the communication load between the vehicle-mounted device 20 and the vehicle-mounted remote controller 30 can be reduced.

(4) Execution of Ejection FIG. 8 is a diagram showing a processing flow regarding remote operation of ejection in the in-vehicle remote control device according to the first embodiment of the present invention. This ejecting operation corresponds to the "mechanical operation" of the present invention.

The remote control unit 31 identifies the operator from which the depression detection signal is output, and if the operator is for ejection (S401: YES), detects the length of the depression time. When the remote control unit 31 detects that the operator is not for ejection (S401: NO), the remote controller 31 executes another process corresponding to the pushed operator (S406).

When the remote control unit 31 detects a long press, ie, a press for a length equal to or longer than a preset threshold time (S402: YES), the remote control unit 32 transmits an eject signal to the vehicle-mounted device 20 via the remote control communication unit 32. (S403). When receiving the eject signal, the ETC control unit 21 of the vehicle-mounted device 20 executes a process of ejecting the ETC card. When the ETC control section 21 of the vehicle-mounted device 20 detects that the ejection has been successfully completed, it transmits information indicating the completion of the ejection to the vehicle-mounted remote controller 30 via the main body communication section 22 .

Upon receiving the information indicating the completion of the ejection via the remote control communication unit 32, the remote control unit 31 converts the notification of the completion of the ejection into voice and emits the sound from the speaker 35 (S404).

With this configuration, the user can eject the ETC card by remote control using the in-vehicle remote control device 30 . That is, the ETC card can be ejected with a simple operation. In addition, since the user can know the completion of ejection of the ETC card by voice, even if the vehicle-mounted device 20 is placed in a position where it is not easy to visually check, the user can surely grasp that the ejection of the ETC card has been completed. be able to.

When the remote control unit 31 detects that it is not long pressed, that is, pressed for a length less than the preset threshold time (S402: NO), the remote control unit 31 emits an error notification of acceptance of ejection from the speaker 35 ( S405). As a result, the user can reliably recognize that the remote ejection operation performed by the user ended in failure.

Next, a vehicle-mounted information acquisition system including a vehicle-mounted remote controller according to a second embodiment of the present invention will be described with reference to the drawings. FIG. 9 is a configuration diagram of an in-vehicle information acquisition system including an in-vehicle remote controller according to the second embodiment of the present invention.

The mobile communication terminal 40 is a so-called mobile phone terminal, smart phone, or the like. The mobile communication terminal 40 includes a body control section 41 , a short-range communication section 42 and an antenna 401 . The body control unit 41 is connected to the short-range communication unit 42 and the antenna 401 and performs overall control of the mobile communication terminal 40 . In addition, the body control unit 41 performs communication functions that the mobile communication terminal 40 originally performs, that is, communication control between contracted communication carriers and free wireless networks. The short-range communication unit 42 communicates with the remote control communication unit 32A of the in-vehicle remote control device 30A.

Next, each process executed by the in-vehicle remote control device 30A according to the second embodiment of the present invention will be specifically described.

(5) Call Via Mobile Communication Terminal FIG. 10 is a diagram showing a call processing flow using the in-vehicle remote controller according to the second embodiment of the present invention.

The remote controller control unit 31A identifies the operator from which the push detection signal is output, and if the operator is for communication (S501: YES), the remote control unit 31A communicates with the mobile communication terminal 40 via the remote controller communication unit 32A. Direct communication is established (S502). At this time, as shown in the above-described processing, if the number of clicks is one, a notification is given that the function is for making a call via the mobile communication terminal, and if the number of clicks is two, the mobile communication terminal You may make it establish two-way communication between.

When the remote controller control unit 31A detects that the operator is not for calling (S501: NO), the remote controller 31A executes another process corresponding to the pushed operator (S504).

31 A of remote control control parts transmit the sound-collection signal which sound-collected with the microphone 37 to the mobile communication terminal 40 via 32 A of remote control communication parts. On the other hand, the remote controller control unit 31A emits the voice call signal from the mobile communication terminal 40 received by the remote controller communication unit 32A from the speaker 35 . Thereby, the user can make a call with the outside using the mobile communication terminal 40 without picking up the mobile communication terminal 40 . That is, the user can make a so-called hands-free call.

(6) Read-out of E-mail Received by Mobile Communication Terminal FIG. 11 is a diagram showing a processing flow of read-out of e-mail using the in-vehicle remote controller according to the second embodiment of the present invention.

The remote controller control unit 31A identifies the operator from which the press detection signal is output, and if the operator is for reading out e-mail (S601: YES), the remote control unit 31A communicates with the mobile communication terminal 40 via the remote controller communication unit 32A. two-way communication is established (S602). At this time, as shown in the above-described processing, if the number of clicks is 1, a notification is given that the function is to read out the e-mail received by the mobile communication terminal, and if the number of clicks is 2, Two-way communication with the mobile communication terminal may be established.

When the remote controller control unit 31A detects that the operator is not for reading out e-mail (S601: NO), it executes other processing corresponding to the pushed operator (S606).

Remote control unit 31A obtains from mobile communication terminal 40 whether or not there is an unread e-mail. If there is an unread e-mail (S603: YES), the remote controller control unit 31A receives the unread e-mail and extracts the text data of the received e-mail. The remote controller 31A outputs the extracted character string from the speaker 35 by executing the TSS function, for example (S604).

If there is no unread e-mail (S603: NO), the remote control unit 31A emits sound from the speaker 35 indicating that there is no unread e-mail (S605).
