Description

  The present invention relates to an in-vehicle information providing apparatus that exchanges information through communication between vehicles and presents the exchanged information to an occupant.

  When you are driving in an unknown place with a vehicle such as an automobile, on the road ahead to the destination, information on road conditions such as freezing and snow, traffic conditions such as traffic jams and traffic closures, information on local events, etc. There are many scenes that are useful for driving if you know beforehand.

  Conventionally, as a method for acquiring information to be provided to passengers in a vehicle, a method of performing data communication by wireless communication using a mobile communication system (for example, 3G) using a wireless base station or a public communication network is known. (For example, patent document 1).

JP 2003-166833 A

  However, information exchange using a mobile communication system that uses a communication infrastructure such as a radio base station or a public communication network may impede active use because it requires a predetermined communication cost to acquire information. There is a problem that communication cannot be performed and information cannot be acquired in remote areas such as mountainous areas where infrastructure is not established.

  The present invention has been made to solve the above-mentioned problems, and provides a technique for acquiring and presenting information useful for vehicle occupants by a method of directly exchanging information between vehicles regardless of communication infrastructure. The purpose is to provide.

  An in-vehicle information providing apparatus of the present invention made to achieve the above object comprises an information collecting means, a communication means, a communication establishing means, an information exchanging means, a storing means, and an information presenting means. And

  By the way, as a condition for exchanging information by inter-vehicle communication, communication with other vehicles is established by the communication establishing means, as long as it is determined that the host vehicle is parked. Then, it is conceivable to exchange information with the other vehicle by the information exchange means. This assumes the operation of exchanging information with nearby vehicles that are also parked while the vehicle is parked in a parking lot, service area, drive-in, or the like. By doing in this way, the information which the vehicle collected by exchanging information with surrounding vehicles while parking can be used after the driving is resumed.

  Therefore, the condition for presenting the driver with information obtained by exchanging information with surrounding vehicles during parking is that, as described in claim 4, it is determined that a person is in the driver's seat. In addition, it is conceivable that the travel-related information is presented by the information presenting means. By doing this, when the driver who was absent from the vehicle due to errands or a break during parking returned to the driver's seat to resume driving, it was related to the new driving that was obtained during parking Information can be presented.

  By the way, the travel-related information obtained by exchanging information with surrounding vehicles is limited to information useful to the driver that matches the purpose and purpose of the vehicle's travel (where to go and what to do). It is desirable to present it to the driver. Therefore, as described in claim 5, the information exchange means further comprises a selection means for selecting the travel related information suitable for the purpose and purpose of the own vehicle from the travel related information received from other vehicles, It is conceivable that the storage means is configured to save the travel-related information selected by the selection means from the travel-related information received from other vehicles as a presentation target in the storage means.

  In addition, as a method for selecting travel-related information, as described in claim 6, the travel-related information is selected based on at least one of a position, a time, and a type related to the purpose and purpose of travel of the host vehicle. It is possible to do. In this way, for example, it is possible to present to the driver by narrowing down to real-time information related to the route periphery to the destination of the host vehicle.

  Next, the in-vehicle information providing apparatus according to claim 7 has the following characteristics. That is, the accepting unit accepts an instruction from the user to request an operation that reflects the travel-related information presented by the information presenting unit. The guidance control means reflects the information indicated by the travel-related information in the future travel contents of the own vehicle on condition that the instruction for requesting an operation to reflect the travel-related information is received from the user by the accepting means. Present. In this way, it is possible to provide assistance to the driver based on the presented travel related information as well as the travel related information obtained by exchanging information with surrounding vehicles.

  Specifically, as described in claim 8, the guidance control unit is configured to provide route guidance for detouring a traffic obstacle indicated by the travel-related information or a stop to an event, and a specific information indicated by the travel-related information. It may be configured to present at least one of instructions on how to deal with an event as guidance information.

  The various kinds of traveling related information as described above are classified into traveling related information collected by the own vehicle and stored in the storage unit 12 each time it is acquired. The storage unit 12 can store a predetermined number of data as travel related information collected by the host vehicle, and the travel related information exceeding the specified number is sequentially deleted from the oldest.

[Description of information exchange process]
Next, the procedure of information exchange processing executed by the control unit 10 will be described with reference to the flowchart of FIG. This process is executed at predetermined intervals (for example, every 10 seconds) while the in-vehicle information providing apparatus 1 is activated.

  When starting the process, the control unit 10 acquires vehicle information from each in-vehicle device through the in-vehicle LAN communication unit 14 (S101). The vehicle information acquired here is information that is used to determine whether or not the host vehicle is parked. Specifically, information on the vehicle speed, the ON / OFF state of the main switch (IG) of the engine or motor, the operation state of the parking brake, the door opening / closing state based on the courtesy switch signal, the detection state of the seating sensor on the driver's seat, etc. Illustrated.

  Next, based on the vehicle information acquired in S101, it is determined whether or not the host vehicle is parked (S102). Here, it may be determined that the vehicle is parked based on the conditions of vehicle speed = 0, main switch = OFF, and parking brake = ON. Further, in addition to the above-described conditions, the parking requirement may include the absence of a driver based on the detection of the seating sensor of the driver's seat and the detection of the opening / closing of the door on the driver's seat side. Good. If the host vehicle is parked (S102: YES), the process proceeds to S103. On the other hand, when the host vehicle is not parked (S102: NO), this process is terminated.

  In S103, which proceeds when the host vehicle is parked, communication is started in the wireless LAN ad-hoc mode by the wireless communication unit 11, and 1 is exchanged with the in-vehicle information providing apparatus 1 mounted on the surrounding vehicle in the communicable range. Establish direct one-to-one communication. And if communication with a surrounding vehicle is established, while traveling related information which the own vehicle holds in the memory | storage part 12 will be transmitted to a communication other party's vehicle, the traveling related information which a communication other party's vehicle will receive will be exchanged. This is performed (S104). The travel-related information exchanged here is the above-mentioned “slip detection information”, “weather information”, “traffic information”, “event information”, and the like.

  Here, the travel related information to be transmitted to the communication partner vehicle is not only the travel related information collected by the own vehicle and stored in the storage unit 12, but has already been obtained by exchanging information with other surrounding vehicles and stored in the storage unit. The travel-related information stored in 12 is also included. Also, the travel related information received from the communication partner vehicle at this time includes travel related information collected by the vehicle itself, and travel related information obtained by exchanging information from other surrounding vehicles.

  In addition, after communication with surrounding vehicles is established, before exchanging travel-related information, first of all, exchanging travel history information indicating the route through which both parties have passed, and the direction of the route that the vehicle of the communication partner plans to proceed in the future The information may be exchanged on the condition that the vehicle can be identified from the vehicle.

[Description of information classification process]
Next, the procedure of information classification processing executed by the control unit 10 will be described with reference to the flowchart of FIG. This process is a process executed in conjunction with the information exchange process described above, and performs a process of organizing and storing travel-related information obtained from surrounding vehicles in the information exchange process.

  When starting the process, the control unit 10 classifies the travel-related information received from the surrounding vehicle by inter-vehicle communication according to the content such as position (route, direction), time, genre (slip, weather, traffic, special event) (S201). ). Then, it is determined whether there is information selected as relevant information corresponding to the purpose and purpose of traveling of the host vehicle from the traveling related information classified by content (S202). When the travel-related information received from the surrounding vehicles includes information selected as the relevant information of the host vehicle (S202: YES), the process proceeds to S203. On the other hand, when there is no information corresponding to the relevant information of the host vehicle (S202: NO), this process is terminated.

  Specifically, the position information included in the received travel-related information is around the route (the guidance route to the destination by the navigation device) from which the host vehicle will travel, and is included in the travel-related information. It is conceivable to select information that is within the valid period of the time and schedule information to be collected as related information. The valid period of the travel related information may be, for example, several hours to several days depending on the type of travel related information. In the case of travel-related information related to special events and entertainment, it may be possible to select information that matches the destination or purpose of the host vehicle as related information. For example, if the golf course is a destination, information on golf is selected. If the destination is a ski area, information on skiing is selected. Or you may comprise so that driving | running | working relevant information applicable to the specific genre designated in advance by the user may be selected as relevant information.

  In S203, which is performed when there is information selected as related information of the host vehicle in the travel related information received from the surrounding vehicles, the storage unit 12 stores the selected related information as travel related information to be presented to the driver. Save to. Here, the travel-related information to be presented is stored as a separate classification from the travel-related information collected by the host vehicle.

  It should be noted that it is possible to discard all of the travel-related information received from the surrounding vehicles that is not selected. Alternatively, depending on the genre, in addition to discarding, it may be possible to store the information in the storage unit 12 separately from the travel-related information to be presented to the driver. By doing in this way, even if the information is not to be presented to the driver, it can be provided to the communication partner vehicle when information is exchanged with another surrounding vehicle later. For example, information related to driving safety such as slip information, weather information, traffic information, and the like that are not selected can be stored, so that information useful for safe driving can be transmitted to more vehicles.

[Description of information presentation process]
Next, the procedure of information presentation processing executed by the control unit 10 will be described with reference to the flowchart of FIG. This process is a process executed after the traveling related information is stored by the above-described information classification process.

  When starting the process, the control unit 10 acquires vehicle information from each in-vehicle device through the in-vehicle LAN communication unit 14 (S301). The vehicle information acquired here is information for determining that an occupant (that is, a driver) has boarded the driver's seat. Specifically, information on the presence / absence of an unlocking operation of the door, the opening / closing state of the door based on the courtesy switch signal, the detection state of the seating sensor of the driver's seat, and the like are exemplified.

  Next, based on the vehicle information acquired in S301, it is determined whether or not the driver has boarded (S302). Here, it is considered that the unlocking operation of the door, the opening / closing of the door on the driver's seat side, and the detection of the seated state of the driver's seat are the requirements for determining that the driver has boarded. When the driver gets on (S302: YES), the process proceeds to S303. On the other hand, when the driver is not in the vehicle (S302: NO), this process ends.

  In step S <b> 303, which proceeds when the driver gets on, the travel-related information to be presented newly acquired this time is read from the storage unit 12, and the content is displayed on the display 26. At this time, if image data is included in the travel related information, the image is also displayed. In addition, a predetermined instruction operation related to the displayed travel-related information is set to be received by the touch panel of the display 26.

  Next, it is determined whether or not an instruction for requesting reflection of the travel-related information displayed in S303 to the travel plan has been received from the user (S304). The reflection request instruction from the user is received through an operation unit (not shown) provided on the touch panel of the display 26, the vehicle console, or the like. For example, it is conceivable that the user individually selects information that needs to be reflected from the list of travel-related information displayed on the display 26. When a reflection request instruction is received from the user (S304: YES), the process proceeds to S305. On the other hand, when an instruction to end the information presentation process is received without receiving a reflection request instruction from the user (S304: NO), this process ends.

  In S305, which is performed when a reflection request instruction is received from the user, guidance processing in which the specified travel-related information is reflected in the travel plan is executed. Specifically, for travel-related information related to slip information and weather information, it is conceivable that a warning message is notified when the vehicle travels from the place. It is also conceivable to notify in advance a message for prompting preparations required for traveling on a road surface with freezing or snow (for example, confirmation of equipment). Further, the position may be displayed on a map with a symbol mark or the like in cooperation with the navigation device 22.

  For travel-related information related to traffic jams and traffic closures on the route to the destination, search for a route that detours the position in cooperation with the navigation device 22 and provides detour guidance, or the position is indicated by a symbol mark or the like. It can be displayed on a map. For travel-related information related to special events and entertainment, it may be possible to search for a route that stops at the position in cooperation with the navigation device 22 and provide stop-by guidance, or display the position on a map with a symbol mark or the like. .
