Description

  The present invention relates to a vehicle parking guidance device and a parking guidance system that are mounted on a plurality of vehicles and mutually provide information related to a parking position through communication with other vehicles.

Conventionally, it is a communication device that mutually provides information on the parking position, and when the vehicle shifts to a state where it will depart from the vehicle, the departure information is transmitted to another vehicle, or when the vehicle transitions to a state where it is parked An invention about a communication device configured to be able to notify that a parked vehicle or a departure vehicle exists in a vehicle that has received these by transmitting parking information to another vehicle is disclosed. (For example, refer to Patent Document 1).
JP 2005-250984 A

  However, in the conventional communication device, for example, a case where a plurality of vehicles receive departure information from a vehicle in a departure state is not considered, and a plurality of vehicles gather at one parking position. Cases arise.

  The present invention is for solving such problems, and a main object of the present invention is to provide a vehicular parking guide device capable of performing parking more smoothly.

  In order to achieve the above object, the first aspect of the present invention is a communication means for communicating directly or indirectly with another vehicle, and detection of possibility of leaving the own vehicle. Means, a waiting-for-arrival detection means for recognizing that the host vehicle is a waiting-for-entry vehicle, a leaving intention confirmation means for confirming a passenger's intention to leave, and an information providing means for providing information to the passenger, When it is detected by the detecting means that there is a possibility of leaving the vehicle, the information indicating that there is a possibility of leaving the vehicle is transmitted to the other vehicle, and then the information indicating that there is an intention to park is received from the other vehicle. And when confirming the occupant's intention to leave by means of leaving intention confirmation means, sending the information indicating that the intention to leave has been confirmed to the other vehicle that has sent information indicating that there is a intention to park, performing the control at the time of leaving, Own vehicle by means of waiting detection When it is recognized that the vehicle is waiting to be received, when information indicating that there is a possibility of leaving the vehicle is received from another vehicle, information indicating that the vehicle intends to park is returned to the other vehicle, and then the other When receiving information indicating that the intention to leave has been confirmed from the vehicle, providing information on the parking position of the other vehicle that has transmitted the information indicating that the intention to leave has been provided to the occupant, performing the control at the time of entry This is a vehicle parking guidance device.

  By mounting this first aspect of the present invention on a plurality of vehicles, it is highly possible that the vehicle waiting for entry can start moving to the parking position before the leaving vehicle actually leaves the parking position. Therefore, it is possible to increase the possibility that the waiting vehicle can secure the parking position. In addition, since the intention to leave is confirmed by transmission / reception with the leaving vehicle, it is possible to avoid a situation where the parking position is waited for in the vicinity of the vehicle where it is unclear whether or not to leave. It is also possible to avoid a situation in which the parking position becomes empty after giving up that the parking position is vacant and moving from the vicinity. From these, parking can be performed more smoothly.

  In the first aspect of the present invention, when receiving information indicating that there is a intention to park from a plurality of other vehicles when performing the control at the time of leaving, the intention to leave the occupant is confirmed by the leaving intention confirming means. Assuming that the information indicating that the intention to leave has been confirmed is sent to the vehicle that has responded the earliest information among the plurality of other vehicles that have returned the information indicating that they are willing to park. Also good. In this way, when there are a plurality of vehicles waiting to be received, information indicating that the intention to leave has been confirmed is transmitted only to the selected one vehicle, so that there are a plurality of vehicles at one parking position. It is possible to avoid situations where people gather.

  Further, in the first aspect of the present invention, when the information indicating that there is an intention to park is received from a plurality of other vehicles while performing the control at the time of leaving, the leaving intention of the occupant is notified by the leaving intention confirmation means. On the condition that it has been confirmed, out of a plurality of other vehicles that have returned information indicating that there is a parking intention, information indicating that the intention to leave has been confirmed may be transmitted to the vehicle closest to the host vehicle. In this way, when there are a plurality of vehicles waiting to be received, information indicating that the intention to leave has been confirmed is transmitted only to the selected one vehicle, so that there are a plurality of vehicles at one parking position. It is possible to avoid situations where people gather.

  Further, in the first aspect of the present invention, the vehicle type information of the host vehicle may be transmitted to another vehicle together with information indicating that there is a possibility of leaving when the leaving control is performed.

  A second aspect of the present invention is a parking guidance system realized by the vehicle parking guidance apparatus according to the first aspect of the present invention mounted on a plurality of vehicles.

  According to the present invention, it is possible to provide a vehicle parking guidance device and a parking guidance system that can perform parking more smoothly.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the accompanying drawings.

  Hereinafter, a vehicle parking guidance apparatus 1 according to an embodiment of the present invention will be described.

It is.

[Constitution]
FIG. 1 is a diagram illustrating an example of the overall configuration of a vehicle parking guidance apparatus 1. The vehicle parking guidance device 1 is configured, for example, by expanding the function of an existing in-vehicle navigation device, and includes, as main components, a communication device 10, a GPS receiver 20, a memory 30, an ignition switch 40, An HMI (Human Machine Interface) 50, a shipping intention confirmation switch 60, and a navigation computer 70 are provided. In addition, the arrow in a figure shows the flow of the main information communication in a vehicle performed using appropriate communication protocols, such as CAN (Controller Area Network), BEAN, AVC-LAN, and FlexRay.

  The communication device 10 is a device for communicating directly or indirectly with another vehicle, and its communication format is an ad hoc communication format that does not require an access point such as DSRC (Dedicated Short Range Communication) or Bluetooth. Alternatively, it may be of a type that communicates with other vehicles via an antenna facility installed in a parking lot. Further, it may have a mechanism equivalent to a mobile phone, a PHS (Personal Handy-phone System), etc., and communicate with other vehicles via a radio base station or the like.

  The GPS receiver 20 receives a radio signal including satellite orbit and time data from a GPS satellite and outputs the radio signal to the navigation computer 70.

  The memory 30 is a storage medium such as an HDD (Hard Disc Drive), a DVD (Digital Versatile Disk), or a CD-ROM, and stores map information. In the map information, the road shape is expressed by the coordinates (latitude, longitude) of node points representing intersections and the like and links connecting the node points, and the number of lanes and road width are attached to each link. Data such as curvature is stored. Moreover, the coordinate area | region is memorize | stored about the facility (a parking lot is included) which has a predetermined area.

  The ignition switch 40 outputs an ignition on signal as a vehicle start request signal and an ACC on signal as a vehicle system activation signal to the navigation computer 70. Moreover, it is good also as what detects the insertion / extraction state of an ignition key, and outputs it to the navigation computer 70. FIG.

  The HMI 50 includes, for example, a display device configured to display an image and allow a user to perform various input operations as a touch panel, and a microphone, a speaker, a buzzer, and the like for voice input / output. The output content of the HMI 50 is determined by the navigation computer 70, and the input content made to the HMI 50 is output to the navigation computer 70.

  The exit intention confirmation switch 60 may be, for example, a GUI (Graphical User Interface) switch set in a display device of the HMI 50 or a dedicated mechanical switch. The departure intention confirmation switch 60 outputs an off signal in a normal state, and outputs an on signal when an occupant operates.

  The navigation computer 70 is, for example, a computer unit in which a ROM, a RAM, and the like are connected to each other via a bus with a CPU as a center, and includes a storage medium, an I / O port, a timer, a counter, and the like. The ROM stores programs and data executed by the CPU. In addition, the navigation computer 70 includes a current position specifying unit 72, a delivery time control unit 74, and the like as main functional blocks that function when the CPU stores and executes a program stored in the ROM on the RAM. And a warehousing control unit 76. The current position specifying unit 72 specifies the current position (latitude, longitude, altitude) of the host vehicle by a calculation based on the time difference of the radio signal received by the GPS receiver 20. In addition, the current position of the host vehicle may be corrected based on outputs from various sensors such as a vehicle speed sensor and a gyro sensor, and various information received via the beacon receiver and the FM multiplex broadcast receiver. The current position of the own vehicle specified in this way is used for route guidance to a destination which is an original function of the in-vehicle navigation device, and also used in characteristic processing of the present invention described later. The functions of the leaving control unit 74 and the receiving control unit 76 will be described later.

[Transmission / reception control]
A vehicle equipped with the vehicle parking guidance apparatus 1 having the above-described configuration, which is parked at a parking position in a certain parking lot and detects that there is a possibility of leaving the vehicle (hereinafter referred to as a leaving vehicle) And the other vehicle (hereinafter referred to as a vehicle waiting for warehousing) that recognizes that it is going to enter the parking lot, the characteristic transmission / reception control of the present invention is performed. .

  Here, the possibility of leaving the vehicle is detected, for example, when the ACC on signal is input from the ignition switch 40. However, the present invention is not limited to this, and it may be detected that there is a possibility of leaving the vehicle when an event that predicts the start of the vehicle has occurred. For example, it may be detected that there is a possibility of leaving the vehicle when the key is inserted into the ignition switch 40, or it may be detected that there is a possibility of leaving the vehicle when the engine is started. Alternatively, it may be detected that there is a possibility of leaving the vehicle when a vehicle speed that is not zero is detected.

  In addition, the recognition that the host vehicle is a waiting-for-entry vehicle is made, for example, when the current position of the host vehicle specified by the current position specifying unit 72 enters the coordinate area of the parking lot in the map information stored in the memory 30. Until the time when the engine stops (or until the time when the vehicle is stopped within a predetermined range or when an event indicating that the vehicle has reached the parking position is detected). May be recognized as a vehicle waiting to be received. Or it is good also as what recognizes that it is a storage waiting vehicle based on a crew member's predetermined operation.

  FIG. 2 is a sequence diagram showing a flow of processing executed in cooperation between the leaving vehicle and the waiting vehicle. The process shown in the figure corresponds to a leaving vehicle when it is detected that one vehicle in the parking lot is parked at the parking position of the parking lot and the vehicle is likely to leave. The

  First, the outgoing vehicle control unit 74 of the outgoing vehicle transmits information indicating that there is a possibility of outgoing to the other vehicle using the communication device 10 (S100). Here, “send to another vehicle” means that communication is possible when the communication device 10 can communicate within a communicable area centered on the own vehicle or when communication is performed via the antenna facility of the parking lot. Information transmission may be performed without specifying the other party in the area. On the other hand, when the communication device 10 is communicable nationwide using the radio network of a mobile phone, information is transmitted to a specific vehicle that has been previously found to exist in the parking lot. In this case, the current position of each vehicle is collected in advance in an out-of-vehicle facility (an information center that provides information communication services, a control station that supervises a wireless base station, etc.) that intervenes in wireless communication (for example, using a GPS facility in the vehicle) It is sufficient that the current position is determined by being transmitted to the facility outside the vehicle).

  When receiving information indicating that there is a possibility of leaving from the leaving vehicle, the entering control unit 76 of the vehicle waiting for entry returns information indicating that there is an intention to park to the leaving vehicle (S102). Note that if there is no waiting vehicle at this time, the following processing is not performed.

  When receiving the information indicating that there is an intention to park from the waiting vehicle for entry, the exit time control unit 74 of the leaving vehicle notifies the occupant to that effect by the HMI 50 (S104). The notification is, for example, an image display or audio output such as “There are vehicles waiting to be received, but please operate the switch when leaving the vehicle from now on”.

  Then, when an on signal is output from the exit intention confirmation switch 60 and the occupant's intention to exit is confirmed, information indicating that the exit intention has been confirmed and information regarding the parking position of the exit vehicle are transmitted ( S106). The information related to the parking position of the leaving vehicle may be, for example, the current position of the leaving vehicle specified by the current position specifying unit 72, and the number specifying the parking position can be recognized by a camera or road-to-vehicle communication. If there is, it may be the number.

  Here, it is assumed that there are a plurality of vehicles waiting to be received, and the outgoing vehicle receives information indicating that the vehicle intends to park multiple times. In this case, information indicating that there is an intention to park first. Information indicating that the intention to leave has been confirmed may be transmitted to the vehicle waiting to receive the vehicle, or information indicating that the intention to leave has been confirmed to the vehicle waiting for receipt closest to the leaving vehicle. May be. The vehicle waiting for warehousing closest to the leaving vehicle can be determined by including the current position of the waiting vehicle for warehousing in information indicating that there is an intention to park, for example. In this way, when there are a plurality of vehicles waiting to be received, a plurality of vehicles are gathered at one parking position by transmitting information indicating that the intention to leave has been confirmed only to the selected one vehicle. Can be avoided.

  In the waiting-for-receipt vehicle that has received the information indicating that the intention to leave has been confirmed, the HMI 50 provides information about the parking position where the leaving vehicle is parked to the occupant (S108). Specifically, the parking position is displayed in a superimposed manner on a display device displaying a map, and the direction of the parking position with reference to the vehicle position is displayed and / or voice-guided.

  As a result, there is a high possibility that the vehicle waiting for entry can start moving to the parking position before the vehicle leaving the parking position actually leaves, so the possibility that the vehicle waiting for entry can secure the parking position is increased. Can do. In addition, since the intention to leave is confirmed by transmission / reception with the leaving vehicle, it is possible to avoid a situation where the parking position is waited for in the vicinity of the vehicle where it is unclear whether or not to leave. It is also possible to avoid a situation in which the parking position becomes empty after giving up that the parking position is vacant and moving from the vicinity. From these, parking can be performed more smoothly.

  FIG. 3 is a diagram schematically illustrating a state in which a leaving vehicle and a waiting-for-entry vehicle communicate in a parking lot. In this figure, there are two vehicles waiting to be received, but there is only one vehicle that has confirmed the intention to leave. Therefore, since guidance regarding the parking position is performed only in the waiting-for-entry vehicle that has obtained the confirmation, there is only one waiting-for-entry vehicle that moves to the parking position based on the guidance of the vehicle parking guidance device 1. As a result, it is possible to avoid a situation where a plurality of vehicles are gathered at one parking position.

  According to the vehicle parking guidance apparatus 1 of the present embodiment, parking can be performed more smoothly.

  In addition, the parking guidance system implement | achieved by mounting the vehicle parking guidance apparatus 1 in a some vehicle is corresponded to the "parking guidance system" in a claim.

  The best mode for carrying out the present invention has been described above with reference to the embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the scope of the present invention. And substitutions can be added.

  For example, the vehicle type information of the host vehicle may be transmitted together with information indicating that there is a possibility of leaving the vehicle from the leaving vehicle. Here, the vehicle type information does not necessarily need to be a detailed vehicle type, and may be any information that can specify the size of the vehicle. In the vehicle waiting to enter, if the size of the own vehicle is larger than the size of the leaving vehicle by a predetermined degree or more, information indicating that there is an intention to park is not returned. By doing this, for example, a large vehicle guided to the parking position where the mini car was parked tried to park, but it could not fit in the parking position, and it was necessary to search for another parking position. It can be avoided. Such an effect is particularly high when the leaving vehicle is in a position where it cannot be seen from the waiting vehicle.

  The present invention can be used in the automobile manufacturing industry, the automobile parts manufacturing industry, and the like.

It is a figure which shows an example of the whole structure of the parking guidance apparatus 1 for vehicles. It is a sequence diagram which shows the flow of the process which a leaving vehicle and a waiting-for-entry vehicle perform in cooperation. It is the figure which represented typically a mode that a leaving vehicle and a waiting-for-entry vehicle communicate in a parking lot.
