Description

  The present invention relates to a vehicle and parking lot management system and a vehicle parking position specifying method. For example, the present invention relates to a system and method capable of providing a parking position where a vehicle is parked in a large-scale parking lot.

  A large-scale parking lot is attached to a shopping mall where a plurality of stores gather. When a user of a store visits with a vehicle, the vehicle is parked in this large parking lot and moved to the store. In the case of a large-scale parking lot, the user stores the parking position of the vehicle. For this purpose, a number is written on the floor of the parking cell and notified, a parking block in which a plurality of parking cells are assembled is numbered, and the block number is notified by a signboard or the like.

  However, in the form of relying on human memory, the vehicle could not be found due to forgetting the number or the like.

  In order to solve the above problem, in Japanese Patent Laid-Open No. 2003-233898, a parking management system using a computer measures the parking position of a vehicle by radio of a user's mobile terminal (main position measuring means), It is proposed that the user and the parking position are stored in association with each other, that the parking position stored by the user is remotely retrieved with a portable terminal, and that the user is confirmed when the parking position is retrieved remotely.

  In this document, in order to improve the accuracy of measuring the parking position of a vehicle, a vehicle sensor that detects the presence of a nearby vehicle in contact or non-contact is provided (position measuring means for improving accuracy).

Further, in this document, regarding user confirmation, when an identifier unique to a mobile terminal such as a telephone number is associated with the user, the mobile phone number is collected at the time of position measurement, and the parking position is retrieved remotely. , Get the phone number of the mobile device. Since the telephone numbers of the portable terminals used for the position measurement and the parking position retrieval match, the identity of the portable terminal used for the position setting and the parking position retrieval is confirmed.
JP 2003-233898 A

  In Japanese Patent Laid-Open No. 2003-233898, the position measuring means for improving the accuracy of measuring the parking position of a vehicle supplements the rough position measurement of the main position measuring means by detecting the vehicle in the vicinity of the sensor. In order to improve the accuracy, it is required to arrange at least in the vicinity of the vehicle parking position, and many sensors need to be installed in the case of a large-scale parking lot.

  In addition, in the user confirmation performed when the parking position stored by the user is remotely retrieved, the identity of the mobile terminal can be confirmed, but if the user loses the mobile terminal, a third party can remove the mobile terminal. Using this, the parking position can be taken out.

  The purpose of the present invention is to make it unnecessary to install a sensor in the parking lot other than the main position measuring means, and to improve the confidentiality of information provided from the parking lot by authenticating the user of the mobile terminal. It is.

  For this purpose, the present invention starts radio wave communication between the vehicle and the parking lot antenna in conjunction with the operation of entering the vehicle by the user, calculates the position of the vehicle as parking position information, and uses it. For example, it is stored in a pair with user information including at least information such as a password that only the user can know. The user information is encrypted and acquired from the vehicle by the parking lot antenna through radio wave communication.

  When obtaining the position in the parking lot of the vehicle parked by the user, the user's identity is authenticated by using information that only the user can know. When the user leaves the parking lot, radio communication is started between the vehicle and the parking lot antenna in conjunction with the user's vehicle exit operation, and user information is acquired from the vehicle and already held. The parking position information of the corresponding user is deleted from the pair of the user information and the parking position information.

  In particular, in order to improve the accuracy of calculation of the parking position linked to the vehicle entry operation and to delete the parking position information linked to the vehicle exit operation, the user's operation on the vehicle can be controlled by the vehicle entry signal or the exit signal. Used as

  Specifically, the engine stop / start signal, parking brake lock / unlock signal, air conditioner stop / start signal, car audio device stop / start signal, car navigation device stop / start signal, door lock / An unlock signal, an IC card insertion / extraction signal of the ETC on-board unit, and the like are used.

  According to the present invention, in order to specify the parking positions of both vehicles in the parking lot, it is possible to make it unnecessary to install sensors in the parking lot other than the main position measuring means. Moreover, the confidentiality of the information provided from a parking lot can be improved by authenticating the user of a portable terminal itself.

  FIG. 5 is an installation diagram of a parking lot.

  The parking lot 201 includes an in-field passageway 2020 as an area where the vehicle passes, and includes parking blocks (a parking block a2030, a parking block b2040, a parking block c2050, and a parking block d2060) as areas where the vehicle is parked.

  Each parking block consists of a parking cell that parks the vehicle. The parking cell is indicated by a white line or the like so that the user can easily identify the position where the vehicle is parked.

  In the present embodiment, the parking block has four areas and the parking block has a configuration of eight parking cells, but any number of configurations may be used according to the parking lot scale.

  Each parking block is provided with each block antenna (block antenna a110, block antenna b111, block antenna c207, block antenna d208). Each block antenna generates a radio wave with a radio wave intensity capable of communicating with a vehicle that has entered the corresponding parking block.

  This means that when the vehicle 101 is parked in a parking cell in the parking block a2030, at least the block antenna a110 has a radio wave intensity such that it is within a communicable range with the vehicle-mounted antenna 109.

  The antenna / parking position correspondence table 113 stores parking position information corresponding to block antenna information. For example, it is stored in advance that the parking block a2030 corresponds to the block antenna a110, and the parking block b2040 corresponds to the block antenna b111.

An overall operation flow of this embodiment will be described. The overall operation consists of the following three steps.
1) Incoming step 2) Parking position information providing step 3) Outgoing step 1) Incoming step will be described.

  In this parking lot management system, each block antenna installed for each parking block continuously generates a beacon radio wave including block antenna information in the parking block.

  The vehicle 101 includes a vehicle-mounted antenna 109 that can receive a beacon radio wave. After the vehicle 101 enters the parking block a2030, the vehicle 101 detects a vehicle entry operation of the user and receives a beacon radio wave including block antenna information of the block antenna a110. The block antenna information, the user information, and the warehousing signal included in the received beacon radio wave are transmitted to the block antenna a110.

  Receiving this, the block antenna a110 transmits the block antenna information, the user information, and the warehousing signal to the parking position calculation server 112 when the block antenna information matches that transmitted by the own block antenna.

  Using the antenna / parking position correspondence table 113, the parking position calculation server 112 converts the parking position information into parking position information corresponding to the block antenna information, and transmits the parking position information to the parking position providing server 114.

  The parking position provision server 114 stores the user information and the parking position information in the parking position storage unit 117 in combination.

  2) The parking position information providing step will be described.

  The parking position providing server 114 holds the user information and the parking position information in combination. In response to the inquiry about the parking position information from the user terminal 103, the parking position providing server 114 authenticates the user of the user terminal 103 using the user information transmitted from the user terminal 103.

  When the authentication is successful, the parking position providing server 114 searches and transmits the parking position information stored in the parking position storage unit 117 to the user terminal 103.

  The user terminal 103 displays the parking position information and shows it to the user.

  3) The delivery step will be described.

  In this parking lot management system, as shown in the warehousing step, each block antenna installed for each parking block continuously generates a beacon radio wave including block antenna information in the parking block.

  The vehicle 101 in the parking block a2030 detects the user's vehicle exit operation, starts receiving the beacon radio wave including the block antenna information of the block antenna, and starts receiving the block antenna information, the user information, and the output included in the received beacon radio wave. The signal is transmitted to the block antenna a110.

  The block antenna a <b> 110 that has received this transmits the block antenna information, the user information, and the exit signal to the parking position calculation server 112 when the block antenna information matches the own block antenna.

  The parking position calculation server 112 issues a deletion instruction to the parking position providing server 114. The parking position providing server 114 deletes the user information and the parking position information stored in the parking position storage unit 117 that match the received user information from the parking position storage unit 117.

  The detailed operation of the warehousing step is shown in FIGS.

  In the present embodiment, it is assumed that block antenna a110 detects the receipt of vehicle 101.

  This will be described with reference to FIG.

  In step S301, the block antenna a110 generates a beacon radio wave.

  Beacon radio waves are constantly generated by all block antennas regardless of vehicle detection.

  The beacon radio wave includes block antenna information.

  The block antenna information is an identifier for individually identifying a plurality of block antennas installed in the parking lot, and in the present embodiment, different numerical values are assigned to the individual block antennas.

  When the user enters the vehicle 101 into the parking block a2030, stops the vehicle in the parking cell, and locks the parking brake, the parking brake sensor 104 detects the locking of the parking brake and controls the vehicle via the vehicle-mounted control network 106. The CPU 105 is notified of parking brake lock.

  When the vehicle-mounted control CPU 105 detects that the parking brake is locked in step S302, the vehicle-mounted control CPU 105 notifies the vehicle operation detecting device 107 of a parking brake lock signal 108.

  In step S303, the vehicle operation detection device 107 detects this as a vehicle entry operation by the input of a parking brake lock signal, and starts specifying the vehicle parking position.

  Specifically, the detection of the beacon radio wave received by the vehicle-mounted antenna is started. The vehicle operation detection device 107 detects a beacon radio wave in step S304.

  Considering the possibility that there is an overlap in the range of the beacon signal transmitted by each block antenna, when receiving multiple beacon signals, select and receive the beacon signal of the block antenna with the strongest signal strength. May be.

  In step S305, the user information is encrypted. The user information is used for user identification and user authentication performed by the parking position providing server 114.

  In the present embodiment, a user name for user identification and a password for authentication are used as user information.

  User information (user name and password) is set in the vehicle operation detection device 107 in advance.

  In addition, in order to maintain the uniqueness of the identification of the user, the user name is issued in advance by the administrator of the parking lot system 102 or a unique identifier possessed by the user, for example, an e-mail of the user terminal 103 An address may be used instead.

  Furthermore, since the vehicle number is already unique, the user name may be used as the vehicle number.

  Further, the encryption of the user information in step S305 is information including personal privacy, and is used for ensuring security because it is used for authentication.

  The vehicle operation detection device 107 transmits the encrypted user information via the in-vehicle antenna 109 in step S306.

  The transmission data is the received block antenna information, user information, and a warehousing signal indicating the warehousing of the vehicle.

  The warehousing signal distinguishes the warehousing and the leaving of the vehicle.

  The transmission destination of the user information may be unicast transmission that specifies and transmits the received block antenna a110, or may be broadcast transmission that does not specify the transmission destination block antenna.

  In step S307, the block antenna a110 receives the communication data from the in-vehicle antenna 109, and checks whether the block antenna information of the received data matches the information transmitted in the beacon radio wave.

  When the vehicle-mounted antenna 109 transmits communication data by broadcast and a block antenna installed other than the parking block a2030 receives this, the block antennas other than the block antenna a110 discard the received data.

  This will be described with reference to FIG.

  The block antenna a110 detects the vehicle 101 in its own antenna in step S401 from the result of the collation in step S307. In step S402, user information is transmitted to the parking position calculation server 112.

  The data to be transmitted are block antenna information, user information, and a warehousing signal. When receiving the data, the parking position calculation server 112 reads the antenna / parking position correspondence table 113 to calculate the parking position, and converts it into parking position data corresponding to the block antenna information in step S404.

  Here, the parking position data is an identifier assigned to each parking block and may be in any format that allows the user to identify the parking block in the parking lot, such as the name of the parking block and the parking block number.

  The parking position calculation server 112 that has obtained the parking position data decrypts the user information in step S405, and transmits the user information and the parking position data to the parking position providing server in step S406.

  The transmission data is user information, parking position data, and a warehousing signal.

  The parking position providing server 114 recognizes that the vehicle has been received by the received warehousing signal, and holds the user information and the parking position data as a pair in step S407.

  The detailed operation of the parking position information providing step is shown in FIG.

  In user terminal 103, in step S501, the user inputs user information (in this embodiment, a user name and a password).

  The user terminal 103 requests parking position data from the parking position providing server 114 in step S502.

  At that time, the user terminal 103 transmits user information input by the user in step S501 in order to receive user authentication by the parking position providing server 114.

  In step S503, the parking position providing server 114 searches the user information stored in the parking position storage unit 117 with the user name included in the received user information, compares the received password with the stored password, and compares the stored password with the user. Authentication is performed, and when the authentication is successful, the parking position data stored in the parking position storage unit 117 is transmitted to the user terminal 103.

  At this time, vehicle-specific vehicle information such as a vehicle number may be used to identify the user.

  In step S504, the user terminal 103 receives the parking position data and displays it on the screen.

  Detailed operation of the delivery step is shown in FIG. 9 and FIG.

  This will be described with reference to FIG.

  The block antenna a110 generates a beacon radio wave in step S601.

  Beacon radio waves are constantly generated by all block antennas regardless of vehicle detection. The beacon radio wave includes block antenna information.

  When the user leaves the vehicle 101 from the parking cell in the parking block a2030, if the parking brake is unlocked, the parking brake sensor 104 detects the unlocking of the parking brake, and the in-vehicle control is performed via the in-vehicle control network 106. The CPU 105 is notified of parking brake unlock.

  When detecting that the parking brake is unlocked in step S <b> 602, the in-vehicle control CPU 105 notifies the vehicle operation detecting device 107 of the parking brake unlocking operation via the parking brake lock signal 108.

  In step S603, the vehicle operation detection device 107 detects this as a vehicle exit operation by inputting a parking brake unlock signal, and starts deleting the vehicle parking position.

  Specifically, the detection of the beacon radio wave received by the vehicle-mounted antenna is started.

  The vehicle operation detection device 107 detects a beacon radio wave in step S604, encrypts the user information in step S605, and transmits the encrypted user information via the in-vehicle antenna 109 in step S606. The transmission data is received block antenna information, user information, and a delivery signal indicating the delivery of the vehicle.
