Description

  The present invention relates to a system in which a third party other than the owner of a car opens and closes a car, such as locking, unlocking, and doors, in order to handle a load on the car.

As a conventional locking / unlocking method for a vehicle, there are a method using a metal key and a remote entry system using wireless communication between the key and the vehicle. These are simply locked and unlocked by the owner of the car, and the key itself needs to be passed to the third party in order to be performed by the third party.
In addition, a third party can lock, unlock, and open / close the door of the vehicle by operating it remotely from a public network such as the Internet, in addition to handing the metal key of the vehicle from the owner. There is a way to do it. In this method, information related to a third party is acquired in advance by the terminal of the car owner, and the information is set in advance. And by accepting the unlocking request from the third party, the owner's terminal operates the unlocking of the car via the network, or the electronic key for unlocking to the third party via the network Unlocking is performed by sending (for example, Patent Document 1).

  In addition, a method is proposed in which requests and operations such as locking / unlocking are aggregated at the center instead of being directly operated via a network remotely (for example, Patent Document 2 and Patent Document 2). 3). Furthermore, a method for registering and notifying information on the parking position of a car on the center has also been proposed (for example, Patent Document 4).

  A customer makes a purchase at a store, and the goods are delivered to a vehicle owned by the customer instead of the customer and loaded. Or, there is a porter service such as a hotel where a guest's baggage is delivered to a guest's own vehicle instead of being loaded by the employee. It is hoped that the usage permission of the third party will be given safely and that the third party's work such as loading will be grasped in real time.

  Conventional methods for locking, unlocking, and opening / closing doors to vehicles from third parties obtain information about the third party in advance for the use of the third party, and obtain that information in advance by the vehicle or the owner. It was necessary to set for the terminal and center. In addition, in order to carry out these operations between the car and the owner and a third party, it is necessary to go through a public network, and there is a possibility that the actual system may be complicated from the viewpoint of safety.

  Furthermore, in the conventional unlocking of vehicles by a third party, methods for creating information and permitting judgment on the third party's terminal have been proposed, but this is often unacceptable in terms of safety. .

  The present invention has been made to solve the above-described problems, and enables safe unlocking without going through a public network and without setting information related to the third party in advance. The purpose of this is to make it possible to grasp in real time the work on the vehicle.

The car owner terminal stores the key information received from the in-vehicle device and the other encryption key, receives information related to the third party from the third party terminal, and receives the third party information and the facility information of the permitted vehicle on the other side. To generate additional information by encrypting with the encryption key, transfer the key information and additional information to the third party terminal as usage permission information,
In addition to the usage permission information received from the car owner terminal, the third party terminal transmits third party information to the in-vehicle device,
The in-vehicle device creates two encryption keys, encrypts information for unlocking the vehicle using one encryption key, and transmits the encrypted key information and the other encryption key to the car owner terminal. The transmitted encryption information and two encryption keys are stored, the key information received from the third party terminal is decrypted with one encryption key, the additional information is decrypted with the other encryption key, and the vehicle is unlocked.
The in-vehicle device, the owner terminal, and the third party terminal directly exchange signals with each other.

  The in-vehicle device, the owner terminal, and the third-party terminal directly transmit / receive information on unlocking the vehicle equipment to each other by short-range wireless communication, and the third-party unlocks the vehicle on which the in-vehicle device is mounted. No need to send / receive information via the public network, because the third party terminal does not directly create / change / add information related to unlocking simply by receiving the information when necessary and simply transferring it to the in-vehicle device. In addition, it is possible to safely unlock the vehicle on which the vehicle-mounted device is mounted without setting information on a third party in advance.

A transmission information generation unit 42 that generates information obtained by adding store-side information as information about a third party to the key information and additional information received from the information storage unit 43 that stores information generated by the transmission information generation unit 42; A short-range wireless communication device 44 that directly transmits and receives information for locking and unlocking the vehicle with the vehicle-mounted device 1 and the car owner terminal 2 is provided.

  The short-range wireless communication includes infrared communication, Bluetooth, UWB (Ultra Wide Band), wireless LAN, and the like. However, these often involve technologies for communicating farther, but it is desirable to make them effective at short distances of up to about 10 m. Also, they do not need to be connected to a public network.

Next, the operation will be described.
First, consider a case where the vehicle stops at a parking lot or the like and the vehicle owner gets out of the vehicle.
The car owner terminal 2 requests the vehicle-mounted device 1 on the vehicle to provide information for unlocking doors, trunks, and the like. At this time, the car owner terminal 2 transmits information about itself to the in-vehicle device 1 through the short-range wireless communication device 34. The in-vehicle device 1 creates two electronic encryption keys A and B, and uses one of the electronic encryption keys (assumed to be A) for vehicle information, vehicle owner terminal 2 information and unlocking. Encrypt various information. The encrypted information (hereinafter referred to as key information) and the other electronic encryption key (assumed to be B) are transmitted to the car owner terminal 2 through the short-range wireless communication device 28. The car owner terminal 2 stores the received information and the other electronic encryption key B in the unlock information storage unit 33. The in-vehicle device 1 stores the contents of the transmitted encrypted information and two electronic encryption keys in the electronic key / user information storage unit 26.

Next, consider a case where a car owner performs shopping or the like, and a store clerk (porter) on the store side delivers goods to the vehicle and loads them.
The vehicle owner needs to pass a key (key information) for unlocking the vehicle to the store. At that time, the car owner terminal 2 first receives the store-side information from the third-party terminal 3 on the store-side by the short-range wireless communication device 34 via the short-range wireless. The received store side information and the information of the vehicle equipment (trunk, door, etc.) permitted to be used are collected into one, and obtained from the in-vehicle device 1 in advance and stored in the unlock information storage unit 33. Is encrypted by the additional information generation unit 32 to generate additional information. Thereafter, the key information and the additional information are transferred as usage permission information from the car owner terminal 2 to the third party terminal 3 through the short-range wireless communication device 34.

Since the key information and the use permission information of the additional information are encrypted with an electronic encryption key having only the vehicle-mounted device 1 and the car owner terminal 2, it is difficult for a third party to tamper with and misrepresent the contents.
When a store clerk (porter) carries the third-party terminal 3 to deliver and load an article to the car owner's car, it is necessary to unlock the vehicle to use the vehicle equipment such as a trunk and a door. At that time, the third party terminal 3 transmits the store side information to the in-vehicle device 1 through the short-range wireless communication device 34 in addition to the key information received from the car owner terminal 2 and the usage permission information of the additional information. The in-vehicle device 1 receives the information from the short-range wireless communication equipment 28.
The in-vehicle device 1 decrypts the received key information with the electronic encryption key A and the additional information with the electronic encryption key B. If the decryption fails, the vehicle is not unlocked because the information has been tampered with or misrepresented, and the use of the vehicle equipment is not permitted.

Further, for example, the following various types of information are compared, and if any one of them is not the same, the same is not permitted.
1. 1. store-side information included in the additional information and store-side information transmitted from the third-party terminal 3 2. information on the car owner terminal 2 included in the key information and information on the car owner terminal 2 stored in the electronic key / user information storage unit 26; If the vehicle information included in the key information and the vehicle information stored in the electronic key / user information storage unit 26 all match, the in-vehicle device 1 is included in the additional information. The permitted facility is identified from the information of the permitted vehicle facility, the vehicle control unit 21 is requested to unlock the corresponding facility, and the vehicle control unit 21 instructs the locking / unlocking operation unit 23 to unlock according to the request. And unlock. At this time, the additional information and the store side information are stored in the electronic key / user information storage unit 26 with information being used.

  Thereafter, a store clerk (porter) having the third party terminal 3 opens and closes a trunk, a door, and the like, and loads articles. When the loading is completed, the store clerk (porter) with the third party terminal 3 sends the lock request to the short-range wireless in addition to the key information and additional information store side information received from the car owner terminal 2 in the same manner as when unlocking. It transmits to the vehicle equipment 1 through the communication device 44. In the vehicle-mounted device 1, the received key information is decrypted with the electronic encryption key A and the additional information is decrypted with the electronic encryption key B, and the vehicle control unit 21 is requested to lock the corresponding equipment.
