Description

  The present invention relates to a navigation device having a function of searching for a route to a destination or displaying a map around the position of a vehicle, and in particular, navigation capable of continuing an operation procedure input during a stop after traveling. Relates to the device.

  The navigation device detects the current position of the vehicle, reads out map data around the vehicle position from a map storage medium such as a DVD or HDD, draws the map data on the map screen and overlays the vehicle mark on the map. draw. When the current position changes due to the movement of the vehicle, the map is scrolled or the vehicle mark on the map is moved accordingly, and the map information around the vehicle position is presented to the user in an easy-to-understand manner.

  The navigation device is provided with a manual input and a voice input as functions for performing an input interface with the user. Input by manual operation is performed by operating a touch screen of a display or operating buttons or a joystick on a remote control. When voice input is performed, input switching is instructed by an input switching button or the like, and after the voice is accepted, the input voice is recognized and the information is input.

  The input operation by the user, particularly the driver, is preferably performed while the host vehicle is stopped from the viewpoint of safe driving. In the case of manual input, there is a risk that the gaze time ahead will decrease due to the gaze on the display. For this reason, it is generally recommended to restrict manual input during driving.

  Patent Document 1 discloses a technique in which an input by a voice input unit is performed when the vehicle is traveling, and an input by a manual input unit is performed when the vehicle is not traveling. As a result, it is possible to input information safely while traveling and to input information quickly while stopping.

JP 09-16891 A

  However, the conventional navigation device has the following problems. While the manual operation input is being performed while stopping at the intersection due to a signal waiting or the like, if the signal changes to blue, traveling must be started. In this case, a restriction is imposed on the manual operation input. For example, when a destination is set while waiting for a signal, a destination setting screen as shown in FIG. 5A is displayed on the display. Here, the user selects a desired display button by manual operation, and when traveling is started midway, as shown in FIG. 5 (b), a display 200 indicating "cannot be operated for safety during traveling". Appears and the manual operation input restriction screen appears. On the manual operation restriction screen, input that is not necessary for complicated operations, such as “Back”, “Destination deletion”, “Home guidance”, etc. is allowed (hatched part in the figure). Input of operation buttons is limited.

  FIG. 6 is a flowchart for explaining an operation example when setting a new destination while the host vehicle is stopped. For example, during the guidance for the destination (step S201), the host vehicle stops due to a red signal or the like (step S202), and at this time, the user starts to set a new destination (step S203). As described above, the user makes a desired input on the destination setting screen of FIG. 5 (a), but the signal turns blue in the middle and the vehicle starts to travel (step S204). The manual operation input restriction screen as shown in b) is displayed (step S205). When the operation is abandoned and the guidance guidance is returned to the map screen display (step S206), the operation information input by the user when stopped is reset (step S207), and the destination setting is returned to the initial state. It will return (step S208).

  On the other hand, if the display is not returned to the map screen display, the vehicle is on standby until the next stop (step S209). When the vehicle stops next (step S210), the input is resumed by manual operation again (step S210). S211). Then, when the vehicle travels again (step S212), it enters a standby state again until the next stop. The destination setting is completed while waiting for the vehicle to stop several times (step S213), and guidance to a new destination is started (step S214). As described above, in the conventional navigation device, all the operations input during the stoppage are wasted after traveling, or even if the operation is continued, it is necessary to wait for the own vehicle to stop, There was a problem in terms of operation and convenience.

  An object of the present invention is to solve the above-described conventional problems, and to provide an in-vehicle navigation device and an input method thereof that can continue an input operation performed during a stop even after traveling.

  The in-vehicle navigation device according to the present invention has a function of searching for a route to a destination and guiding the searched route, and further has the following configuration. Manual operation input means for inputting various information by manual operation, voice input means for inputting various information by voice, and storage means for storing operation information input by the manual operation input means while the vehicle is stopped And, when the own vehicle shifts from the stop to the travel, the input operation performed during the stop is continued after the travel based on the operation information input by the voice input means and the operation information stored in the storage means. Operation continuation means.

  The input method to the in-vehicle navigation device according to the present invention includes a first input step for inputting information by manual operation while the host vehicle is stopped, and a first input when the host vehicle shifts from stop to travel. The operation information input in the step is stored in the memory, the second input step in which information is input by voice operation when the host vehicle shifts from the stop, and the second input step. Based on the operation information and the operation information stored in the memory, and continuing the input operation performed during the stop after traveling.

  Here, the input operation performed while the vehicle is stopped is intended for all operations performed by the user in the in-vehicle navigation device, and in order to achieve the initial purpose, a plurality of inputs are received from the user. It is what is needed. For example, an operation for setting a destination, an operation for various settings of the navigation device, and the like are included.

  According to the in-vehicle navigation device of the present invention, the operation information input by manual operation when the host vehicle is stopped is stored, and the operation information input by voice during traveling and the stored operation information are stored. Since the input operation performed during the stop can be continued, even if the manual operation input is restricted after traveling, it is possible to effectively utilize the operation input by the user during the stop. In addition, the input operation can be performed quickly and safely regardless of the running state of the vehicle.

  The best mode for carrying out an in-vehicle navigation device according to the present invention will be described below in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration of an in-vehicle navigation device according to an embodiment of the present invention. The navigation device 1 includes a GPS receiver 10, a self-contained navigation sensor 11, a VICS / FM multiplex receiver 12, a manual operation input unit 20, a voice input unit 21, an input interface 22, a storage device 30 for storing map data, and a voice output.

  The GPS receiver 10 receives radio waves from an artificial satellite (GPS satellite) and measures the current position and current direction of the vehicle. The measured position information includes data such as the latitude and longitude of the vehicle. The self-contained navigation sensor 11 includes a vehicle speed sensor that detects a moving distance and a gyro sensor that detects a rotation angle. Output signals from the GPS receiver 10 and the self-contained navigation sensor 11 are supplied to the control unit 80, and the control unit 80 calculates the current position and direction of the vehicle based on these output signals.

  The VICS / FM multiple receiver 12 sequentially receives the current road traffic information outside the vehicle via the antenna 13. VICS (Vehicle Information & Communication System) provides road traffic information in real time, and transmits information by FM multiplexing (text broadcasting), radio wave beacon, and optical beacon.

  The manual operation input unit 20 and the voice input unit 21 constitute an input of the navigation device 1. Through these inputs, the user gives various instructions and settings such as a search to the destination, a search for a route to the destination, and a display screen setting change to the navigation apparatus 1.

  The manual operation input unit 20 includes, for example, input by a plurality of operation keys 52 provided at the lower part of the display 51, input by a touch panel of the display 51, and a plurality of key inputs by the remote controller 22. The voice input unit 21 transmits a user voice input via a voice input microphone (not shown) to the input interface 23. The input interface 22 receives input information from the manual operation input unit 20, converts an input audio signal into a digital signal, and transmits the digital signal to the control unit 80.

  The storage device 30 is a recording medium such as a hard disk drive (HDD), DVD, or CD-ROM, and stores map data, addresses, telephones, facilities, and other databases required for the navigation device. The storage device 30 can store programs for executing various functions of the navigation device.

  The data communication control unit 31 may include a communication device that transmits and receives data in the navigation device, or may externally attach a mobile phone or an electronic device having a communication function to the navigation device. . The data communication control unit 31 performs road-to-vehicle communication with an external traffic information center server, etc., and sequentially acquires real-time dynamic information of road traffic information or can acquire necessary information through inter-vehicle communication. .

  The audio output unit 40 includes a speaker 41, and outputs sound from the speaker 41 under the control of the control unit 80. For example, as information until reaching the destination, a voice prompting attention in the direction of the course is output before the intersection, or when the user performs voice input interactively to the navigation device, Give instructions. Furthermore, the audio output unit 40 outputs music or audio from TV reception when the navigation device performs an audio function or a TV reception function.

  The display control unit 50 is connected to the display 51 and displays a map on the display 51 or on the map based on data read from the storage device 30 or the data memory 70 under the control of the control unit 80. A vehicle mark indicating the current position of the vehicle, a route to the destination, a guidance display at a branch point such as an intersection, and a landmark of the facility are combined. Furthermore, when information is input from the operation input unit 20 or the like by the user, it is displayed. The display control unit 50 preferably includes a VRAM such as a FIFO, stores data related to maps, roads, and guidance displays read from the storage device 30 and the data memory 70 in the VRAM, and stores the map data read from the VRAM. Combine various data.

  The program memory 60 stores various programs executed in the vehicle-mounted navigation device, and these programs are executed by the control unit 80. As the program memory 60, for example, a rewritable RAM may be used to read a program stored in the storage device 30, or a ROM that stores a program in advance may be used. The programs include, for example, a program 61 for searching for a route to a destination, a program 62 for setting / changing a map displayed on the display 51, and the like. Furthermore, a program 63 for restricting input by manual operation when the host vehicle shifts from stop to travel and an operation continuation program 64 for continuing user input operations performed while the vehicle is stopped are included. (This will be described later).

  The data memory 70 stores processing results of various calculations processed by the control unit 80, map data 71 read from the storage device 30, and the like. Further, the data memory 70 stores the searched route data 72 and the road traffic information 73 received from the VICS / FM multiplex receiver 12 when the route to the destination is searched. Furthermore, in order to continue the input operation performed when the host vehicle is stopped after traveling, the input operation information 74 related to the input operation is stored. As the data memory 70, DRAM, SRAM, flash memory, or the like can be used, and the contents of the data memory 70 may be transferred to the storage device 30.

  The vehicle state information 78 supplies a signal indicating on / off of a parking brake of the vehicle to the navigation device 1. This signal can be used together with the vehicle speed pulse when detecting whether or not the vehicle is stopped.

  A feature of the present invention is that a user's input operation performed while the host vehicle is stopped can be continued even after traveling. Hereinafter, this feature will be described.

  FIG. 2 is an operation flowchart for executing the above feature. As an example, an input operation when the user sets a new destination when the vehicle is stopped waiting for an intersection signal will be described.

  Guide display for guiding the route to the destination is performed on the display 51 (step S101). Next, when the own vehicle is stopped by a red signal at the intersection (step S102), the state is detected by the vehicle speed pulse and / or the parking brake, and this is transmitted to the control unit 80. When recognizing the stop of the host vehicle, the control unit 80 releases the restriction on the manual operation input in accordance with the manual operation input program 63 (step S103). Thereby, the user inputs a command for setting a new destination (step S104). As a result, the destination setting screen as shown in FIG.

  For example, when “A Golf Course” in Tokyo is set as a new destination, an example of the operation procedure is as shown in FIG. The operation procedure is to narrow down destinations hierarchically. First, after giving an input 100 of “golf course”, an input 110 for selecting “Tokyo” from the name of the prefecture is performed. give. Next, an input 120 for selecting “XX city” from the city name in Tokyo is given, and then an input 130 for selecting “A golf course” is given. If there is no doubt that this is the final destination, a “decision” input 140 is provided.

  As described above, from the destination setting screen shown in FIG. 3A, the user inputs the “golf course” button 150, and then inputs the “Tokyo” button 160 (step S106). At this time, if the intersection signal turns blue and the vehicle starts to travel (step S106), the control unit 80 detects that the vehicle has shifted from stop to travel by detecting the vehicle speed pulse. recognize. When shifting from the stop to the running, the control unit 80 checks whether or not the setting of a new destination is completed (step S107). When the destination setting (here, “A golf course”) is completed, the control unit 80 searches for a route to “A golf course” in accordance with the route search program 61 and guides the searched route. Is performed by the display 51 or voice (step S114).

  On the other hand, when the destination is being set, the control unit 80 temporarily stores the user's input operation performed during the stop as input operation information 74 in the data memory 70 in accordance with the operation continuation program 64 (step S108). ). Whether or not the destination setting has been completed can be determined by checking whether or not the “decision” input 140 (see FIG. 4) indicating the completion of the destination setting has been performed. In the above example, since the user's operations performed while the vehicle is stopped are the inputs 100 and 110 to “Golf course” and “Tokyo”, the input operation information 74 indicates that these operation inputs have been performed. Information to be stored is stored.

  With the start of traveling, the control unit 80 restricts the input of the manual operation according to the manual operation input restriction program 63 (step S109). However, in the present embodiment, at the same time, the control unit 80 displays an input switching mode button 170 as shown in FIG. 3B (step S110). The input switching mode button 170 is not subject to manual operation input restriction, and may be instructed by a user's manual operation. Alternatively, the input switching mode button 170 is displayed and the voice “input switching” is displayed. If there is an input, an input instruction may be accepted.

  When the input switching mode is instructed by the user (step S111), the control unit 80 takes over the input operation performed during the stop by voice operation (step S112). The control unit 80 recognizes from the input operation information 74 stored in the data memory 70 that the user has already performed input operations for “golf course” and “Tokyo”, and accepts subsequent operations by voice. .

  When voice input is performed, for example, the control unit 80 causes the user to output a question from the speaker 41 “Please speak the name of a city in Tokyo”, and the user “ ○ Reply with “city”. Next, the speaker 41 repeats “Are you sure in XX city” and the user answers “high” when it is correct. Setting up to “A golf course” as the final destination is performed in such a conversation format (step S113). When the setting up to “A golf course” is performed, the control unit 80 searches for the optimum route to “A golf course” and starts guidance guidance for the searched route even if the vehicle is traveling ( Step S114).

  On the other hand, if the user does not give an instruction for the input switching mode while traveling (step S111), the state where the manual operation input is limited is continued, and the next time the vehicle stops, the data memory 70 is input. The operation information 74 is read, and the destination setting is resumed (step S115). In this case, the operation after the input 120 of “XX city” is performed.

  In addition, even when switching to the voice input mode once during driving, it is also possible to return to the state where the voice input is terminated and the manual operation input is restricted by instructing the input switching mode again. is there. In this case, the operation input information added by the voice input is also stored as the input operation information 74, and the operation information added by the voice input is also taken into account when the vehicle is stopped next time. Settings are resumed.

  As described above, according to the present embodiment, even when traveling is started during the user's manual operation input, the manual operation input can be continued by voice operation or voice input after the start of traveling. It is possible to effectively use the user's operation input in the above without wasting it, and to quickly complete the intended operation regardless of the traveling state of the vehicle. Further, since voice input is used during traveling, the driver can perform an input operation while confirming the safety ahead without gazing at the display.

  In the above embodiment, an example in which the user sets a new destination is shown. However, this is only an example. Of course, in addition to such an operation, an operation for changing the setting of the display, a stop point in the middle, and the like. It can be applied to various operations such as an operation for searching.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific embodiments, and various modifications can be made within the scope of the gist of the present invention described in the claims. Deformation / change is possible.

  The vehicle-mounted navigation device according to the present invention is particularly useful in a navigation device having restrictions on manual operation input after traveling.
