A program to be executed by the control device 205 is written in the ROM, and the control device 205 executes various processes shown in FIG. 3 when the CPU executes arithmetic processing according to the program.

  Next, the control contents executed by the ECU 108 of the vehicle-mounted navigation device 100 and the control device 205 of the parking lot management device 200 will be described based on the flowchart shown in FIG. First, when the in-vehicle navigation device 100 that is a vehicle-side device detects that the vehicle has entered the parking lot, it executes Step S10.

  Detection of entering the parking lot is performed as follows. As described above, the DSRC communication device 201 is provided at the entrance of the parking lot, and a polling signal is periodically transmitted from the communication device 201. When the communication device 111 of the in-vehicle navigation device 100 receives this polling signal, it detects that it has entered the parking lot. When it is detected that the vehicle has entered the parking lot, the ECU 108 transmits the entry notification information from the communication device 111 to the DSRC communication device 201 of the parking lot management device 200. The entrance notification information received by the DSRC communication device 201 is supplied to the control device 205, so that it can be detected that the vehicle has passed the parking lot entrance. Therefore, the communication detection device 111 and the ECU 108 of the in-vehicle navigation device 100 and the DSRC communication device 201 and the control device 205 of the parking lot management device 200 constitute an entrance detection device as claimed. The entrance detection device is not limited to this. For example, an opening / closing type bar may be provided at the entrance of the parking lot, and the entrance of the vehicle may be detected by opening / closing the bar or the like. The vehicle passing may be detected by analyzing the image captured by the camera.

  The entry notification information transmitted from the in-vehicle navigation device 100 to the parking lot management device 200 in step S10 may be only information indicating that the host vehicle has entered the parking lot, but the phone number or mail of the mobile phone owned by the driver. An address may be included. When the telephone number or mail address of the mobile phone owned by the driver is included in the entrance notification information, the telephone number or mail address is stored in the memory 109 in advance.

  When the entrance notification information is supplied from the DSRC communication device 201, the control device 205 of the parking lot management device 200 executes step S20. In step S20, an ID is determined, and the determined ID is transmitted to the in-vehicle navigation device 100 via the DSRC communication device 201. Further, when the entry notification information includes the telephone number or mail address of the mobile phone, the telephone number or mail address is stored in the memory 204 in association with the determined ID. This process corresponds to the registering means in the claims.

  When the communication device 111 of the in-vehicle navigation device 100 receives the ID transmitted from the parking lot management device 200, the communication device 111 supplies the ID to the ECU 108. When the ID is supplied, the ECU 108 stores the ID in the memory 109 (step S30). Until this step S30, the process is executed when passing through the parking lot entrance, and the vehicle passing through the parking lot entrance is parked in the parking space determined by the driver by the driver's driving operation. become.

  The next step S40 is a process executed when the driver once leaves the vehicle and then returns to the parking lot and tries to leave the vehicle. The predetermined information transmission operation is performed by the driver. It is executed by doing. In step S <b> 40, departure request information is transmitted from the communication device 111 toward the middle-range communication device 202 of the parking lot management device 200. The departure request information includes the ID stored in step S30.

  Upon receiving the departure request information, the mid-range communication device 202 supplies the departure request information to the control device 205. When the departure request information is supplied, the control device 205 determines the departure order in accordance with the order determination rule for the ID included in the departure request information (step S50). In the present embodiment, the order determination rule is such that the order in which the departure request information is received is used as it is. However, the present invention is not limited to this mode. For example, the departure request information includes point information given in accordance with the usage status of at least one of the parking lot and the surrounding facilities of the parking lot, and the order is determined. A rule is good also as a rule of determining a departure order in order with many points contained in departure request information among departure request information received within a fixed period.

  Subsequently, the parking lot management apparatus 200 executes steps S60 to S80. In step S60, the congestion status at the parking lot exit is confirmed. In this embodiment, as will be described later, it is possible to detect that the vehicle has passed through the parking lot exit, and the vehicle permission information is sequentially transmitted to the vehicle that has transmitted the vehicle departure request information. Is sending. In step S60, the congestion situation of the parking lot exit is confirmed from these. Specifically, the difference between the number of vehicles that have transmitted the departure permission information and the number of vehicles that have passed through the parking lot exit is calculated as a numerical value indicating the congestion status of the parking lot exit. The above difference in the number of vehicles started to move from the parking position to the parking lot exit to get out of the parking lot, but the number of vehicles that have not yet exited from the parking lot exit, that is, the number of vehicles that have reached the parking lot exit nearby. And the total number of vehicles that have already reached the parking lot exit. Therefore, the difference in the number is calculated as a numerical value indicating the congestion status of the parking lot exit. Note that the congestion status of the exit may be confirmed by other means, for example, a camera that captures the vicinity of the exit is installed, the image captured by the camera is analyzed, and the congestion status of the exit is confirmed. Also good.

  In step S70, the time until the vehicle that has transmitted the departure request information is permitted to leave, that is, the waiting time that must be waited until the vehicle that has transmitted the departure request information is permitted to leave. Is calculated. This waiting time is calculated as follows. First, the number of vehicles waiting for the departure permission information at the present time is determined based on the departure order determined in step S50 and the number of vehicles that have transmitted the departure permission information. Next, a value obtained by multiplying the number by the unit required time set as the time required for one vehicle to leave the parking lot is set as the waiting time.

  In step S80, information indicating the waiting time calculated in step S70 (hereinafter referred to as waiting time information) and a waiting instruction are transmitted to the in-vehicle navigation device 100 of the vehicle that has transmitted the departure request information in step S40.

  The waiting time information and the waiting instruction transmitted from the parking lot management device 200 are received by the communication device 111 of the in-vehicle navigation device 100. The waiting time information and the waiting instruction received by the communication device 111 are supplied to the ECU 108. When they are supplied, the ECU 108 displays a message indicating a standby instruction and a waiting time on the display 110 and outputs the message from the speaker 113 (step S90).

  As a result, the driver of the vehicle can know the waiting time, so that the driver's stress is reduced compared to waiting in a state where it is unknown when the departure permission information is transmitted. In step S80 described above, predetermined additional information may be further transmitted, and in step S90, the additional information may be output from either or both of the display 110 and the speaker 113 of the in-vehicle navigation device 100. The additional information can be anything, for example, an advertisement. During the waiting time, the vehicle occupant is relatively free, so when an advertisement is output, there is a high possibility of paying attention to the advertisement. Therefore, a high advertising effect can be expected. However, the additional information is not limited to advertisements, and may be news or music, for example. This is because even if it is not an advertisement, the effect of eliminating the passenger's spare time can be obtained.

  The parking lot management apparatus 200 checks the exit status after executing Step S80 (Step S100). The processing in step S100 is the same as that in step S60 described above. Then, in step S110, it is determined whether or not the permitted time has come. Specifically, the difference in the number of vehicles confirmed in step S100, that is, the difference between the number of vehicles that have transmitted the departure permission information and the number of vehicles that have passed through the parking lot exit is equal to or less than a predetermined number (for example, about several vehicles). Then, after the ID for transmitting the departure permission information becomes the ID of the vehicle that has transmitted the departure request information in step S40, it can be detected that another vehicle has exited from the parking lot exit. In this case, it is judged that the permit time has come.

  The detection that the vehicle has exited from the parking lot exit is transmitted from the communication device 111 by communication between the communication device 111 of the in-vehicle navigation device 100 and the DSRC communication device 201 provided at the parking lot exit. And being received by the DSRC communication apparatus 201. Moreover, every time it detects that the vehicle has exited from the parking lot exit, the departure request information is received, but the ID of the earliest departure order among the IDs that have not yet transmitted departure permission information. Departure permission information is transmitted to the vehicle. Then, every time the departure permission information is transmitted, the ID for transmitting the next departure permission information is updated to the ID in the next departure order.

  When step S110 is negative determination, it returns to step S100 and continues confirmation of an exit condition. On the other hand, if the determination in step S110 is affirmative, in step S120, departure permission information is transmitted using the mid-range communication device 202 to the vehicle that has transmitted departure request information in step S40. Further, when the mobile phone number or the mail address is stored in the memory 204 in association with the ID for transmitting the departure permission information, the departure permission information is also stored in the mobile phone number or the mail address using the telephone device 203. Send.

  When the departure permission information is transmitted from the parking lot management device 200, the departure permission information is received by the communication device 111 of the in-vehicle navigation device 100, and the departure permission information is immediately output from the display 110 and the speaker 113 which are notification devices. A message indicating that the vehicle is available is output (step S130). In step S <b> 130, a reception confirmation signal indicating that the departure permission information has been received is transmitted from the communication device 111 to the parking lot management device 200.

  Further, when the departure permission information is also transmitted to the mobile phone number or the e-mail address, the departure permission information is also output from the mobile phone. Therefore, the driver of the vehicle can receive the departure permission information even outside the vehicle by registering his / her mobile phone number or mail address. Therefore, when the waiting time notified in step S90 is long, the mobile phone can be carried out of the vehicle. However, when the mobile phone is carried outside the vehicle, the vehicle is generally in an ignition-off state. In the ignition-off state, a reception confirmation signal is transmitted to the parking lot management apparatus 200. Will not be. The parking lot management apparatus 200 executes a process of canceling the departure permission when the reception confirmation signal is not transmitted within a predetermined time set in a relatively short time after the departure permission information is transmitted. .

  When the driver is on the vehicle and the message is output from the display 110 and the speaker 113, the driver drives the vehicle toward the parking lot exit. When the vehicle passes through the parking lot exit, a departure notice is transmitted from the communication device 111 of the in-vehicle navigation device 100 in response to a polling signal from the DSRC communication device 201 provided at the parking lot exit. (Step S140). Then, the departure notification is received by the DSRC communication device 201 (step S150). The departure notification received by the DSRC communication device 201 is supplied to the control device 205, whereby the parking lot management device 200 can detect that the vehicle has passed the parking lot exit. The detection that the vehicle has passed through the parking lot exit is not limited to the above-described mode. For example, an openable bar or the like may be provided at the parking lot exit, and the vehicle passing may be detected by opening or closing the bar or the like. Then, a camera that images the parking lot exit may be provided, and an image captured by the camera may be analyzed to detect vehicle passage.

  As described above, according to the embodiment described above, the congestion status of the parking lot exit is sequentially confirmed, and the departure permission information is transmitted based on the congestion status of the parking lot exit (S100 to S120). Therefore, it can be ensured that the exit of the parking lot is not crowded.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the above-mentioned embodiment, The following embodiment is also contained in the technical scope of this invention, and also the summary other than the following is also included. Various modifications can be made without departing from the scope.

  For example, in step S20 described above, the information to be transmitted to the in-vehicle navigation device 100 includes the parking position designation information for designating the parking position in addition to the ID. In step S30, the parking position designation information is notified to the driver. You may make it do. In this way, the parking position can be managed by this system. In addition, well-known various means, such as providing a vehicle detection sensor in each parking space, can be used whether each parking space is an empty state or it is parking.

  When there are a plurality of exits in the parking lot, in step S40, exit designation information for designating the exit position may be transmitted together with the departure request information. When transmitting the exit designation information, the occupant of the vehicle designates which exit is to be used by using the operation switch group 107 and the remote controller 117 as exit designation means. The exit may be designated by voice. When there are a plurality of exits in the parking lot, the parking lot management apparatus 200 sequentially determines the congestion status for each exit. In addition, the departure order is also determined for each exit, and whether or not the permitted time has come is also determined for each exit.

  Furthermore, when there are a plurality of exits in the parking lot, the parking lot management apparatus 200 may prompt the vehicle driver to exit from another exit instead of the exit designated by the exit designation information. Specifically, an exit road condition detection means for detecting the congestion condition of the road connected to each exit is provided, and the road connected to the exit designated by the exit designation information is congested, but other exits When it is detected by the exit road condition detection means that the road to be connected is not traffic jam, a message prompting to change to an exit that is not traffic jam is transmitted to the in-vehicle navigation device 100. The in-vehicle navigation device 100 that has received the message causes the display 110 or the speaker 113 to output the message. In this way, when a message prompting the change is output from the display 110 or the speaker 113, the driver can re-designate another exit and transmit the departure request information, thereby causing traffic congestion. It is possible to leave the parking lot from the exit. As the exit road condition detecting means, various known means for detecting a traffic jam condition can be used.

  In addition, when the departure permission information can be transmitted to the mobile phone as in the above-described embodiment, the vehicle driver carries the mobile phone when the waiting time is found to be long. The possibility of going out of the vehicle is high. When the departure permission information is received by the mobile phone while out of the vehicle, the driver needs to send the departure request information again after returning to the vehicle. If the waiting time when the departure request information is transmitted again becomes longer, he / she hesitates to go out of the vehicle during the waiting time. Therefore, when the parking lot management apparatus 200 receives the departure request information having the same ID again, it is preferable to determine the order earlier than the departure order determined by the order determination rule described above. It is possible to variously set how much the order is advanced. For example, the order may be the earliest, or the departure order may be determined on the assumption that the departure request information has been received a predetermined time ago. If the departure order is advanced in this way, it is relatively easy to get out of the vehicle and effectively use the time when the waiting time is long.

  Also, if the difference between the number of vehicles that have transmitted the departure permission information and the number of vehicles that have passed through the parking lot exit is a predetermined number, such as the number of vehicles, the ID for issuing the next departure permission A travel distance determining means for determining a travel distance for the corresponding vehicle to travel from the parking position to the parking lot exit may be provided, and the departure permission information may be output in consideration of the travel distance in addition to the difference in the number of vehicles.

  Specifically, in the above-described embodiment, when it is detected that one vehicle has exited from the parking lot exit in a state where the number difference is not more than a predetermined number, the departure permission information is immediately issued. However, after detecting that one vehicle has come out from the parking lot exit, the departure permission information is issued after a predetermined time has elapsed. In this way, by leaving the departure permission information after a predetermined time has elapsed, it can be expected that another vehicle will leave the parking lot exit during the predetermined time. Can get out of the parking lot smoothly. Then, by shortening the predetermined time as the parking position is farther from the exit, the vehicle reaches the parking lot exit at regular intervals. By doing in this way, the departure from a parking lot can be made especially smooth. As the moving distance determining means, for example, it is possible to include the number of the parking position of the vehicle in the departure request information and determine the moving distance from the number of the parking position. Moreover, when the parking position is designated at the time of ID assignment by the parking lot management apparatus 200, the moving distance may be determined by determining the parking position from the ID included in the departure request information.

  In addition, each parking space in the parking lot is provided with a movement restriction device that can switch between a state that restricts the movement of the vehicle and a state that permits the movement, and the departure permission information is transmitted after the vehicle starts parking. Until then, the movement restriction device may be in a state of restricting movement of the vehicle.

  Moreover, when a vehicle that has not transmitted the departure permission information is about to exit from the exit, a violation fee may be collected at the exit. Whether or not the vehicle has not transmitted the departure permission information is determined from the vehicle navigation device 100 by the communication between the communication device 111 of the vehicle navigation device 100 and the DSRC communication device 201 provided at the exit at the exit. It can be confirmed by acquiring. In addition, as a method of collecting a fee, for example, there is a method in which a bar is provided at the exit and a fee collector is provided.

  Further, when a vehicle that has not transmitted the departure permission information is about to exit from the exit, a violation may be notified at the exit and guided to a waiting place.

  Moreover, you may provide an exit separately in the vehicle using this parking lot departure management system, and the vehicle which does not use this system.
