Moreover, although mentioned later for details, the traveling control means 103 shall output the information regarding automatic driving | running | working (it is set as ACC here). Note that ACC is an automatic operation that is positioned at level 1 in SIP (Strategic Innovation Creation Program).

  FIG. 2 is a schematic view of the vehicle information providing apparatus 101 as viewed from the user (driver) side of the vehicle sitting in the driver's seat of the vehicle. An information display unit 204 described later is provided as an instrument display that displays at least various states.

  FIG. 3 shows a block diagram of the vehicle information providing apparatus 101. The vehicle information providing apparatus 101 includes a vehicle information terminal (vehicle information input means) 210 and a multiplex communication input / output terminal (multiplex communication input / output means) 211 for inputting / outputting various information (vehicle state signals) relating to various vehicle states. Control means comprising, for example, a microcomputer for controlling the operation information terminal 212 capable of inputting an operation instruction signal from the predetermined operation means 213, the vehicle interface (vehicle I / F) means 201, and the vehicle information providing apparatus 101 202, a storage means 203 comprising a non-volatile memory such as a flash memory or an EEPROM in which the processing program of the control means 202 is stored, and an information display for visually informing various information (various states of the vehicle) to the vehicle user Part 204 and auditory information providing means 205 for aurally informing various users (various states of the vehicle) to the vehicle user. And notifying means 206, connected to the output side of the control unit 202, in accordance with a command signal from the control means 202 on the information display unit 204 and a driving unit 207 for outputting a display drive signal.

  In this case, the control means 202 can acquire automatic driving related information (for example, destination information described later) related to automatic driving of the vehicle via the multiplex communication input / output terminal 211 (or the vehicle information terminal 210).

  The auditory information providing unit 205 includes a sound / speech synthesis unit 221 connected to the output side of the control unit 202, an amplifier 222 that amplifies an output signal (sound / speech output signal) from the sound / speech synthesis unit 221; And a sound generator 223 such as a speaker for outputting an amplified signal from the amplifier 222. Here, when the vehicle is a motorcycle, the sounding body 223 may be a helmet speaker housed in a helmet worn by a passenger (user) who rides on the motorcycle.

  The operation means 213 includes an operation input unit for performing various operations related to automatic driving of the vehicle. For example, a substantially cross key type operation input unit including a cursor button and a determination button installed on a steering wheel can be applied. An operation instruction signal output from the operation unit 213 when the vehicle user operates the operation unit 213 is input to the control unit 202 through the operation information terminal 212 and the vehicle interface unit 201. This operation instruction signal is also input to the travel control means 103 via the in-vehicle LAN 102. Note that the operation means 213 may be a touch panel type operation input unit instead of the cross key type operation input unit described above.

  Next, the vehicle 100 (for example, the control means 202, the travel control means 103, the navigation control means 104) when displaying the automatic driving related information related to the automatic driving of the vehicle on the information display unit 204 with reference to FIGS. ) Will be described.

  First, in step S1 of the flowchart shown in FIG. 4, the traveling control means 103 receives a vehicle state signal via at least one of the vehicle information terminal 210 and the multiplex communication input / output terminal 211, and the vehicle engine is started. Detect that.

  Next, in step S2, the travel control means 103 determines whether or not the destination at the time of automatic driving can be predicted based on the past travel record information of the user (that is, the travel history information of the user). Execute the process. That is, this means that the traveling control means 103 performs the prediction of the destination during the automatic driving traveling based on the past traveling history information of the vehicle user.

  For example, if it is a commuting time zone on weekdays, the user is expected to go to the same destination (for example, Tokyo Station used for commuting) every time. In the case of this example, the travel control means 103 determines whether or not the destination during automatic driving can be predicted from the current day of the week, the current time, and past destination information (travel history information). Execute judgment processing.

  Here, the traveling control means 103 executes a process for predicting that the destination at the time of automatic driving traveling is “Tokyo Station” when the current day of the week is Wednesday and the current time is 7:30 am. . When the traveling control means 103 determines that the destination at the time of automatic driving can be predicted in this way (when it is determined “YES” in step S2), the traveling control means 103 automatically determines the determination result and the destination information. Related information is transmitted to the control means 202 via the in-vehicle LAN 102, the multiplex communication input / output terminal 211, and the vehicle interface means 201.

  Next, in step S3, when the control means 202 determines that the destination at the time of automatic driving travel can be predicted based on the automatic driving related information, the destination information 250 regarding the destination is displayed on the information display unit 204. The information display unit 204 is controlled so as to be displayed.

  The destination information 250 as the automatic driving related information includes, for example, a driving state display 251 indicating the driving state of the vehicle and a message display 252 indicating the destination (see FIG. 5). As the driving state display 251, for example, a character display “automatic driving” can be applied, and as the message display 252, for example, a character display “the destination is Tokyo Station” can be applied.

  Next, in step S <b> 4, the control unit 202 performs destination correctness determination processing for determining whether or not the destination information 250 displayed on the information display unit 204 is a correct destination. Here, it is assumed that the control unit 202 determines that the destination information 250 displayed on the information display unit 204 is a correct destination.

  Next, in step S <b> 5, the control unit 202 determines whether or not the user starts automatic driving using the operating unit (for example, an automatic driving start switch) 213. Here, it is assumed that the user turns on the automatic driving start switch to start automatic driving. At this time, the operation instruction signal output from the operation unit 213 when the user turns on the automatic driving start switch is also input to the traveling control unit 103 via the in-vehicle LAN 102, and the control of the automatic driving traveling is started. Is done.

  Next, in step S6, when the control means 202 determines that the vehicle has started the automatic driving based on the operation instruction signal, the vehicle state information 260 and the automatic driving control of the vehicle are operating. The information display unit 204 is controlled so that the operation state information 270 indicating the route to the destination and the route guidance screen 280 for guiding the route to the destination are displayed on the information display unit 204 (see FIG. 6).

  The vehicle state information 260 is displayed below the information display unit 204. For example, a digital vehicle speed display unit 261 that digitally displays the traveling speed of the vehicle, a fuel consumption display unit 262 that displays the average fuel consumption of the vehicle, An outside air temperature display unit 263 that displays the air temperature is included.

  The operation state information 270 that is information related to automatic driving is displayed in a substantially central portion of the information display unit 204. For example, an ACC operating display 271 indicating that automatic driving (ACC) is operating, and a model of the own vehicle are schematically shown. Vehicle vehicle mark 272, ACC vehicle speed setting display 273 indicating the set vehicle speed of ACC, preceding vehicle mark 274 schematically showing a preceding vehicle traveling in front of the host vehicle, and the host vehicle being a preceding vehicle An arrow display 275 schematically showing that the vehicle is following the rear is included.

  In addition, navigation information (map image) displayed on the upper side of the information display unit 204 can be applied to the route guidance screen 280 that is information related to automatic driving. For example, an arrow image 281, an intersection name image 282, And a time image 283 showing the required time to the destination.

  Note that when the map image is displayed on the route guidance screen 280, the travel control unit 103 instructs the navigation control unit 104 to output the map image to the destination. And the navigation control means 104 shall transmit a map image to the vehicle information provision apparatus 101 via in-vehicle LAN102. Here, the transmission of the map image is not limited to the one using the in-vehicle LAN 102, for example, a dedicated transmission line for transmitting the map image is provided between the vehicle information providing apparatus 101 and the navigation control means 104. May be.

  Next, when it is determined in step S2 (when the destination prediction determination process is executed) that the control means 202 determines that the destination during automatic driving is unpredictable, the destination related to setting the destination is determined. The information display unit 204 is controlled so that the setting screen 290 is displayed on the information display unit 204 (step S7).

  The destination setting screen 290 is, for example, automatic driving related information configured by a title display 291 and a voice recognition microphone mark 292 (see FIG. 7). As the title display 291, for example, a character display “Destination setting” can be applied, and as the microphone mark 292, for example, a symbol display imitating the shape of a microphone can be applied.

  When it is determined that the destination information 250 displayed on the information display unit 204 is incorrect in the above-described step S4 (during execution of the destination correctness / incorrectness processing), the control means 202 has been displayed so far. In order to display the destination setting screen 290 on the information display unit 204 instead of the destination information 250, display switching processing of the information display unit 204 is executed.

  In this case (that is, when “NO” in step S4), the control unit 202 outputs an operation instruction signal output from the operation unit 213 when the user operates the operation unit 213 (for example, a destination setting switch). When received, the display switching process is executed based on the operation instruction signal.

  Next, in step S8, the control unit 202 determines whether or not the user starts automatic driving using the automatic driving start switch. Here, “YES” is determined in step S8, and the user starts the automatic driving using the automatic driving start switch. At this time, an operation instruction signal output from the operation unit 213 when the user turns on the automatic driving start switch is also input to the travel control unit 103 and the navigation control unit 104 via the in-vehicle LAN 102.

  Next, in step S9, the destination is set by the user during automatic driving by using a microphone (voice input unit) and a voice identification unit (not shown). The voice identification unit is installed at an appropriate location in the vehicle so that voice (voice data) emitted by the user can be input, and the voice identification unit has a function of identifying voice data from the microphone.

  Here, when the user utters the destination of the automatic driving toward the microphone, the voice identification unit encodes the voice data from the microphone and transmits it to the navigation control means 104 as a voice command. The navigation control unit 104 executes a voice recognition process based on the recognition result (the voice command) from the voice identification unit and searches for a destination. Then, the searched destination information is transmitted to the control means 202 via the in-vehicle LAN 102.

  Next, in step S10, the control unit 202 causes the information display unit 204 to display the destination information 255 as the automatic driving related information on the information display unit 204 based on the searched destination information. Perform display control.

  The destination information 255 includes, for example, a driving state display 256 indicating the driving state of the vehicle and a message display 257 indicating the destination (see FIG. 8). As the driving state display 251, for example, a character display “automatic driving” can be applied, and as the message display 252, for example, a character display “the destination is Ueno Station” can be applied. Thereafter, display information (vehicle state information 260, operation state information 270, route guidance screen 280) as shown in FIG. 6 is displayed on the information display unit 204.

  The travel control means 103 determines that the manual driving travel is started when the user performs the steering (handle) operation, the accelerator operation, and the brake operation in step S8 described above, and the manual driving travel is started. A manual driving instruction signal indicating this is transmitted to the control means 202 via the in-vehicle LAN 102.

  When the control means 202 determines that the vehicle has started manual driving based on the manual driving instruction signal (that is, when it is determined “NO” in step S8), the normal display as shown in FIG. The information display unit 204 is controlled so that the screen (manual operation screen) 300 is displayed on the information display unit 204.

  At this time, the normal display screen 300 as vehicle state information displayed on the information display unit 204 is, for example, a pointer-type vehicle speed display unit 310 that displays the traveling speed of the vehicle in an analog manner, and an analog display of the engine speed of the vehicle. A pointer-type rotation speed display unit 320 for displaying the remaining amount of fuel in an analog manner, a shift indicator display unit 340 for displaying a shift position, and a direction indication display unit 350 for indicating the traveling direction of the vehicle. The fuel consumption display unit 262 and the outside air temperature display unit 263 are configured.

  As described above, according to the present embodiment, when the control unit 202 determines that the destination at the time of automatic driving traveling can be predicted, the destination information 250 is displayed on the information display unit 204, and the purpose at the time of automatic driving traveling is displayed. When it is determined that the place cannot be predicted, the information display unit 204 is controlled so that the destination setting screen 290 is displayed on the information display unit 204.

  Therefore, if the destination can be predicted, the destination information 250 (an example of information related to automatic driving) is displayed. Therefore, the user can visually recognize the destination during automatic driving without performing any special operation. Therefore, it is possible to provide easy-to-understand information related to automatic driving that is important for the user during automatic driving. In addition, if the destination cannot be predicted, the destination setting screen 290 is displayed on the information display unit 204 instead of the destination information 250, so that it is possible to provide a more friendly and user-friendly vehicle information providing apparatus. There is an advantage.

  Further, in the present embodiment, the travel control means 103 that performs automatic driving control of the vehicle performs prediction of the destination during the automatic driving based on the travel history information of the user of the vehicle, so that the user can perform a special operation. It is possible to set a destination for automatic driving without performing the operation, and there is an advantage that convenience can be improved.

  In the present embodiment, when the control unit 202 determines that the vehicle has started the automatic driving travel, the route guidance screen 280 (an example of the automatic driving related information) for guiding the route to the destination is displayed on the information display unit 204. The information display unit 204 is controlled so as to be displayed, and when it is determined that the vehicle has started manual driving, the information display unit 204 is controlled so that the normal display screen 300 is displayed on the information display unit 204. Is.

  Therefore, since the route guidance screen 280 to the destination is displayed at the start of the automatic driving travel, the user can visually recognize the route guidance screen 280 to the destination without performing a special operation. A vehicle information providing apparatus with improved convenience can be provided. Further, when the vehicle driving state is switched from automatic driving driving to manual driving driving for some reason (for example, when the user operates the steering), the normal display screen (manual driving screen) 300 is displayed. There is an advantage that the driving support in consideration of the state of the vehicle can be performed.

  In addition, this invention is not limited by the above-mentioned embodiment and drawing. Changes (including deletion of constituent elements) can be added to the embodiments and the drawings as appropriate without departing from the scope of the present invention.
