Description

  The present invention relates to an apparatus for automatically releasing a door lock based on a request from a service center when a door is locked after a key is left behind in a vehicle.

In the past, when a key was left in the car and the door was locked, a worker was called by calling the service center and the door was unlocked using a special instrument.
None

  The problem is that it takes a long time for the user to release the door lock, and for the service center, the schedule adjustment for staffing is complicated and the labor cost is increased.

  Therefore, an object of the present invention is to enable the door lock of the vehicle related to the in-key to be quickly released based on the operation of the service center when a so-called in-key is reported. In this case, the system configuration is suppressed at a low cost and the misuse of others can be reliably prevented.

  In order to achieve the above-mentioned object and to solve the problems, a door unlocking device for a vehicle according to the present invention includes a controller for driving a door unlocking motor based on a command signal from the outside. Based on the technical premise of a release device, the controller is provided with an emergency drive unit for driving a door lock release motor by a command signal from the driver's mobile phone, and the driver's mobile phone is provided with the mobile phone. On the other hand, a release signal generation unit is provided for transmitting a command signal to the emergency drive unit based on a short message having a specific content transmitted from the service center.

  According to such a configuration, by transmitting a short message from the service center to the driver's mobile phone, the mobile phone can activate the emergency drive unit of the controller and operate the door lock release device. . If the driver has a mobile phone, the door lock can be immediately released by a short message transmitted from the service center.

  It is speedy because it does not require the dispatch of personnel, and it is possible to save the trouble of schedule adjustment and labor costs of dispatch staff.

  Short messages are sent directly by connecting a telephone line without going through the provider's server device, so that characters and other data are sent. Prompt action is possible.

  Short messages can use kana-kanji, numbers, pictograms, figures, etc., and even short sentences themselves function as encryption or passwords. The system cannot be abused with a simple configuration.

  According to the automobile door lock release device according to the present invention, the door lock can be quickly released by operating the service center. The user does not have to wait for the arrival of the temporary staff, and the service center only needs to send a short message with a specific content to the driver's mobile phone. I can do it.

  It is only necessary to provide the driver's mobile phone with a release signal generator that transmits a command signal to the emergency drive unit based on a short message from the service center, which can be handled by software, and the introduction cost can be kept low. I can do it.

  FIG. 1 shows an embodiment of an automobile door lock releasing device according to the present invention. The door lock release device includes a controller 14 that drives a release motor 12 of the door lock device 11 based on a wireless command signal from the outside. Usually, the controller 14 functions to release the door lock from a distance by a wireless key owned by the driver. However, when the so-called in-key is used, the conventional door lock device 11 cannot be released without using a wireless key or a tangible key inserted into the keyhole, and the driver cannot open the door of the vehicle.

  The door lock release device according to the present invention is provided with an emergency drive unit 15 in the controller 14 so that the door lock device 11 can be released by following a certain procedure when a tangible key or wireless key is left in the vehicle. .

  The emergency drive unit 15 can be operated by the mobile phone 21 owned by the driver, and operates the emergency drive unit 15 via the release signal generation unit 22 of the mobile phone 21 to release the door lock. Do.

  In order to make the mobile phone 21 perform such functions, the present invention uses a short message S transmitted from the service center (road service company or the like) 20 with which the driver has a contract to the mobile phone 21. N is a public line.

  The short message S is called by various brand names such as short mail, sky mail, C mail, P mail, and light mail depending on the company that provides the service. A short sentence of about 160 characters (in case of Kana-Kanji) is transmitted as data. Other models are also compatible, and sometimes use simple images, sounds, and animations.

  The short message S is used in the present invention in that it can guarantee the first communication immediately and secondly the confidentiality of transmission data. This will be explained.

  First, the short message S can be sent directly to the desired call destination mobile phone 21 when the line service company of the mobile phone 21 is the same. Since it is not communication via the provider's server device as in general e-mail, the short message S can be sent simultaneously with the call of the other party's telephone. For this reason, there is no communication delay caused by access congestion of the server device as in e-mail. If the service center 20 transmits a short message S to the driver's mobile phone 21 on the basis of a request from the driver (usually a request by telephone using the mobile phone 21), the mobile phone 21 immediately receives the short message. S can be received.

  Secondly, the short message S is short sentence data with a certain restriction on the length, but since it can use characters such as kana, kanji, alphabet, and Arabic, it is sophisticated even if it is short. It becomes a cipher string. For example, the short message S that can transmit data exceeding 70 characters is a ciphertext with much higher accuracy than a PIN code used in a bank is a four-digit number.

  The short message S used in the present invention does not require the received driver to confirm the content (text). This is because it suffices that the release signal generation unit 22 of the mobile phone 21 can operate the emergency drive unit 15 based on the received short message S.

  Therefore, the data content of the short message S may be a random character string, an audio signal, or an image signal. The content of the short message S transmitted from the service center 20 is desirably set individually so that the service center 20 transmits a unique short message S to the mobile phone 21 of the driver by contract with the driver. . The driver does not need to know the content of the short message S. This is because the door only needs to be opened in an emergency.

  The short message S transmitted from the service center 20 to the mobile phone 21 activates the release signal generator 22. The cancellation signal generation unit 22 is set in advance so as to be activated and operate the controller 14 (emergency drive unit 15) when receiving a short message S having a specific content, by the setting by the service center 20 in advance. The content of the short message S does not matter. A short sentence of about 4 numbers may be used. In any case, the short message S is transmitted as a kind of ciphertext string having a meaning that is difficult for outsiders to obtain.

  According to this configuration, when the driver forgets to put the key in the car, the mobile phone 21 is used to contact the service center 20. The service center 20 transmits a preset short message S to the mobile phone 21. Unlike the electronic mail, the short message S is a direct call, so the mobile phone 21 can receive it immediately. If the driver is standing near the door with the mobile phone 21, the release signal generator 22 is activated based on the short message S to generate a command signal to the emergency drive unit 15 of the controller 14. The door lock device 11 is driven and the door is unlocked promptly.

  The time from when the driver contacts the service center 20 until the door opens can be within a few minutes. The driver's waiting time is greatly shortened because there is no need for the operation staff to rush to the site as in the past. Further, since the service center 20 only has to call the driver's mobile phone 21 and send the short message S, there is no trouble of dispatching human resources and the processing cost can be greatly reduced.

  Note that the content of the short message S may be the same for the customer. However, in order to ensure the security of confidentiality, it is preferable to use individual data for each group by grouping customers individually or for each customer.

  The command signal transmitted from the release signal generation unit 22 to the emergency drive unit 15 of the controller 14 may be the same as the command signal transmitted by the wireless key. However, in order to ensure safety, the command signal of the wireless key is kept secret, and it is difficult for the driver to know the data contents. Therefore, the command signal generated by the release signal generation unit 22 may be a content uniquely set by the service center 20 as long as the emergency drive unit 15 can drive the controller 14 in response to the command signal.

  Similarly to the wireless key, the cancel signal generator 22 may have a small device that generates radio waves and infrared rays. Since the radio generator is often mounted on the mobile phone 21 due to the need for data exchange or the like, it is not necessary to mount the radio generator independently, and those devices can be shared for generating command signals.

It is a block diagram which illustrates the door lock release device concerning the present invention.
