Description

  The present invention relates to a vehicle antitheft system that provides a vehicle antitheft service using information communication, and more particularly to a vehicle antitheft system having a plurality of security levels.

  Automobile users suppress the occurrence of damage by self-defense measures such as wearing anti-theft devices to protect their vehicles from theft. In addition, in order to reduce the damage caused by theft, join theft insurance. However, in recent years, the techniques of vehicle theft have become more sophisticated, and it has become impossible to effectively prevent theft simply by attaching the antitheft to the vehicle.

  In addition, since the user cannot know the past theft occurrence situation at the parking place that is arbitrarily selected, when the user sets the security level of the anti-theft device, the security level is compared with the theft occurrence level of the parking place. The setting value may be too low. Furthermore, the user may not activate the anti-theft device with the intention of parking for a short time.

  Therefore, a vehicle theft prevention system that sets a security level based on vehicle theft information at a parking place has been proposed. Specifically, multiple security levels are prepared for the vehicle anti-theft information prevention service provided by the management center, and in places where theft occurrence level is high, the security level is increased to make it easier to detect by raising the abnormality detection level, Conversely, by lowering the detection level in a low place to make it difficult to detect, an optimum security level is set according to the situation. (See Patent Document 1).

JP 2003-085676 A

  In the example of Patent Document 1, the detection level is basically changed, and the degree of difficulty in unlocking the vehicle itself is not changed. In other words, simply changing the detection level of a stolen act does not change the level of difficulty in releasing the security of the vehicle itself, so if you can proceed smoothly, theft before the security guards and police officers come There is a fear. However, the higher the security level in the dark clouds, the more difficult it is to release the security, but the more difficult it is to be stolen, but the more difficult it is for the user and the convenience becomes worse.

  The in-vehicle device 100 is configured to transmit data indicating that the state of the vehicle is normal to the management center 200 every predetermined time (for example, every 10 minutes) stored in advance in the memory 105. Thereby, in the management center 200, when normal data is no longer transmitted from the vehicle-mounted device 100, it can be determined that some abnormality has occurred in the parked vehicle. Alternatively, the management center 200 may inquire about the vehicle status to the in-vehicle device 100 every predetermined time (for example, every 10 minutes), and the in-vehicle device 100 may transmit data related to the vehicle status to the management center 200.

  The management center 200 includes a server 201 composed of known computers, workstations, and the like, a communication device 202, a monitoring control panel 203, and the like.

In addition, the management center 200 is configured so that the in-vehicle device 100 can be remotely operated.

  The management center 200 includes three databases A to C. The database A stores data on the user who uses the vehicle anti-theft system and the vehicle, and data on the operating status of the in-vehicle device 100. The database B stores data related to the setting of the theft occurrence level, such as information related to the parking place of the vehicle and vehicle theft information related to the vehicle theft in the past. Examples of past theft information include the location of the theft, time, vehicle type, details of the occurrence of the anomaly, details of the crime (mischief, vandalism, vehicle theft, etc.), distinction between attempted or attempted. The database C stores data necessary for determining the occurrence of an abnormality in the vehicle based on the transmission data from the in-vehicle device 100 and analyzing the content of the abnormality.

  FIG. 6 shows an example in which a key strength level corresponding to a security level, a release method, an abnormality detection method, a threshold value thereof, an alarm when an abnormality is detected, and a security level update time are combined. There are five security levels from level 0 to level 4, and the higher the level value, the higher the security level (less likely to be stolen). Details of each security level are described below.

  At security level 0, the door is unlocked, there is no means for unlocking the door, and there is no method for releasing the security level. Further, since no abnormality detection is performed, a threshold value for vibration detection is not set. Therefore, no alarm is given when an abnormality is detected. Since level 0 is the most dangerous state, the security level update interval is set to 30 sec.

  Security level 1 is when the door is locked, and the door is unlocked with an electronic key 110 such as a mechanical key or wireless key that is inserted into a normal key cylinder and locked / unlocked, and opened with the mechanical key or electronic key 110. When locked, the security level is canceled (becomes level 0). As an abnormality detection method, a vibration sensor included in the intrusion sensor 109 works. When the vehicle vibration exceeds a predetermined threshold without normal unlocking, an abnormality is detected and the hazard lamp 125 blinks. Let me know the abnormality. The threshold for vibration detection is set to the maximum (the sensitivity is the worst). The security level update interval is set to 5 minutes.

  The security level 2 is fixed to the door locked state by an electric door lock latch (E latch) 121 in a state where the door is locked. Only the electronic key 110 such as a well-known wireless key can be unlocked (release of the E latch), and cannot be unlocked with a mechanical key. When unlocked by the electronic key 110, the security level is released (becomes level 0). In addition, as a method of detecting abnormality, the door lock position switch included in the vibration sensor and intrusion sensor 109 works, and vibration is generated without normal unlocking, or the door lock position is in an open state (abnormal unlock). When an error occurs, an abnormality is detected, and when an abnormality occurs, the abnormality is notified by blinking of the hazard lamp 125 and a buzzer included in the alarm device 124. Although the threshold value for detecting an abnormality is large, the sensitivity is better than that in the case of security level 1. The security level update interval is set to one hour.

  Security level 3 is a state where the door is locked and the power supply to the door lock latch (E latch) 121 is cut off by the latch electric dividing circuit 122 and is mechanically and electrically fixed in the locked state. is there. The door can be unlocked only by a special operation such as unlocking by a command signal from the management center 200, and cannot be unlocked by the mechanical key and the electronic key 110. When unlocked by the special operation, the security level is released (becomes level 0). In addition, as an abnormality detection method, vibration detection, abnormality unlocking, and current detection included in the intrusion sensor 109 work, and vibration is generated without normal unlocking, or the door lock position is opened. In addition, an abnormality is detected when the door is opened and an electric current is generated due to lighting of an indoor lamp, etc. In the event of an abnormality, a siren with a louder volume than the buzzer is added to the flashing of the hazard lamp 125 and the buzzer sound included in the alarm device 124. An abnormality is notified by sounding 126. The threshold for detecting anomalies is moderate, but the sensitivity is better than in the case of security level 2. The security level update interval is set to 3 hours.

  Security level 4 is a state where the door is locked, and the door can be unlocked only by the biometric authentication of the user by the camera 102 or the recognition sensor 104. The operation of the electronic verification prohibiting circuit 123 causes the mechanical key, the electronic key 110, and the special key It cannot be unlocked by operation. When it is determined that the user is a user by the biometric authentication, the security level is canceled (becomes level 0). In addition, vibration detection, abnormality unlocking, current detection, and vehicle monitoring work as an abnormality detection method. Vehicle monitoring periodically monitors information taken by the camera 102 while monitoring a person approaching the vehicle with the peripheral monitoring sensor 101. Sent to the management center. That is, at level 4, a method of directly viewing as abnormality detection is added. If it is determined that there is an abnormality by these detection methods, in addition to the blinking of the hazard lamp 125, the buzzer sound included in the alarm device 124 and the siren 126, the notification device 127 causes an error to the management center 200 via the communication device 116. To report. The threshold for detecting an abnormality is the minimum of the five security levels, and in principle, the security level is not changed. The security level update interval is set to 12 hours.

  The condition for abnormality determination at each security level includes a condition of a level lower than the current level. For example, in the case of security level 3, in addition to the case where the current value exceeds a predetermined threshold, the case where the vibration of the vehicle detected by the vibration sensor included in the intrusion sensor 109 exceeds the predetermined threshold (level 2 abnormality) (Determination condition), it is also determined as abnormal when the door is pry open or when the door is unlocked with something other than the mechanical key / electronic key 110 (level 1 abnormality determination condition).

  In the above example, when the security level is canceled, the level is set to 0. However, the level may be lowered by one level.

  Although the above-described security level, release condition, abnormality determination condition, and the like are stored in the memory 105 in advance, the latest one may be downloaded from the management center 200. Moreover, the user may be able to set in the in-vehicle device 100 by an input device (not shown). Furthermore, the content set in the portable terminal 401 or the PC 402 may be sent to the in-vehicle device 100 via the management center 200. In this case, the information may be sent directly from the portable terminal 401 or the PC 402 to the in-vehicle device 100 without going through the management center 200.

FIG. 2 shows an example in which the security level is set by a combination of the theft occurrence level and the user's schedule information. The setting level in the normal area where theft is not frequent is indicated by a solid line, and the setting level in the frequent theft area is indicated by a broken line. It can be seen that the setting level in the theft-prone area is set to be one rank stricter (higher) than the setting level in the normal area. In other words, there is no setting of level 0 in the frequent theft areas, and level 4 is set when the vehicle is separated from the vehicle for 1 hour or more. Similarly (level 3 in the normal area) Similarly, in an area where theft is much lower than the normal area, the rank may be set slightly lower (lower) than the set level in the normal area. Note that the relationship between the time (T) from when the vehicle is parked to the next use of the vehicle and the normal security level is set as follows.
(1) Level 0: T ≦ 1 minute or less (t1)
(2) Level 1: 1 minute (t1) <T ≦ 30 minutes (t2)
(3) Level 2: 30 minutes (t2) <T ≦ 1 hour (t3)
(4) Level 3: 1 hour (t3) <T ≦ 24 hours (t4)
(5) Level 4: 24 hours (t4) <T

FIG. 3 shows an example in which the security level is set by a combination of the theft occurrence level and the distance between the vehicle and the user. The setting level in the normal area where theft is not frequent is indicated by a solid line, and the setting level in the frequent theft area is indicated by a broken line. It can be seen that the setting level in the theft-prone area is set to be one rank stricter (higher) than the setting level in the normal area. In other words, there is no level 0 setting in areas where frequent thefts occur, and level 4 occurs when the vehicle is more than 50 km away. Similarly (level 3 in the normal area) Similarly, in an area where theft is much lower than the normal area, the rank may be set slightly lower (lower) than the set level in the normal area. The relationship between the distance (D) from the vehicle and the normal security level is set as follows.
(1) Level 0: D ≦ 5 m (L1)
(2) Level 1: 5 m (L1) <D ≦ 1 Km (L2)
(3) Level 2: 1 km (L2) <D ≦ 50 km (L3)
(4) Level 3: 50 km (L3) <D ≦ 100 km (L4)
(5) Level 4: 100 km (L4) <D

(Security level determination process)
A security level determination process for determining a security level according to the theft occurrence level, the user's schedule, and the distance between the vehicle and the user will be described with reference to FIG. This process is repeatedly executed together with other processes in a control program executed by a CPU (not shown) included in the security ECU 114.

  When the user's vehicle is parked (S200: YES), the current position information of the vehicle detected by the GPS 107 is transmitted to the management center 200 (S210). The management center 200 refers to the database B of the server 201 based on the received current position information of the vehicle, and calculates the theft occurrence level of the parking area including the current position of the vehicle (S211). Specifically, 1) types of parking lots such as home parking lots, contracted parking lots, temporary rental parking lots, blue sky parking lots, 2) presence or absence of parking lot doors, 3) presence or absence of parking lot managers, 4) past The theft occurrence level is calculated based on the distance from the place where the theft occurred and 5) the parking start time.

  Then, the management center 200 requests the user's location information and schedule information from the user (mobile terminal 401 or PC 402) registered in the database A (S212). When the user receives a request from the management center 200 (S213), the user confirms his / her current position with the portable terminal 401 or the PC 402, and confirms his / her schedule (S214), and uses the current position data and the next vehicle. The transmission date and time (schedule information, or only the time is acceptable) is transmitted to the management center 200 (S215).

  As a method for confirming the current position, a device other than the portable terminal 401 or the PC 402 may be used. Further, any schedule stored in the portable terminal 401 or the PC 402 or recorded in the notebook may be used as the schedule. As for the schedule, the vehicle use schedule for a predetermined period may be sent in a batch, such as within the next week.

  When the current position is confirmed by the portable terminal 401 or the PC 402, the current position data displayed on the portable terminal 401 or the PC 402 is automatically converted into a data format usable by the management center 200 and then transmitted to the management center 200. You may do it. Conversely, format conversion may be performed by the management center 200.

  Information on the current position of the user may be acquired by communication between the vehicle and the portable terminal 401 or the PC 402. That is, the vehicle transmits a current position inquiry request to the portable terminal 401 or the PC 402, and the portable terminal 401 or PC 402 returns the current position data to the vehicle.

  The management center 200 calculates the distance between the user and the vehicle from the received current position data of the user (S216) and the current position of the vehicle. Then, the security level according to the distance of the user is determined with reference to FIG. Moreover, the time until the date and time when the vehicle is used next is calculated from the received schedule information of the user and the current date and time. Then, referring to FIG. 2, the security level according to the user's schedule is determined. Of the two security levels, a safer security level is determined as the recommended security level and transmitted to the in-vehicle device (S218).

For example, when there is a 45-minute meeting at a distance of 100 m from the vehicle in an area where normal theft occurs, the security level based on the distance in FIG. 3 is level 1, and the security based on the schedule in FIG. Level is level 2. In this case, since a safer security level is selected, level 2 is set as the recommended security level.

(Modification of security level determination process)
Even in the same area, the level of theft varies depending on the parking location and surrounding environment in the vicinity of the police station, in the parking lot of a house, and in the parking lot of a company. Therefore, a process for determining a more secure security level by setting the theft occurrence level finely with a data table for calculating the risk of details of the database as shown in FIG. 5 will be described. Steps S300, S310 to S316, S318, and S319 in FIG. 5 correspond to steps S200, S210 to S216, S218, and S219 in FIG. 4, respectively, and step S317 is added. For this reason, the detailed description about a corresponding step (S300, S310-S316, S318, S319) is omitted.

  Hereinafter, a process corresponding to step S317 in FIG. 5 will be described. First, in a region (city, ward, town, village, character, town), a basic theft occurrence level is set based on the past number of vehicle thefts occurring in the region. Next, the risk of being easily stolen is determined for each facility. For example, since it is considered relatively safe within a predetermined range from the police station, the risk is set to −2. Monthly parking lots and places where people are sparse have a risk level of +2, because suspicious people are not sufficiently checked. Then, the basic theft occurrence level plus the danger level is set as the theft occurrence level.

  You may memorize | store the theft generation | occurrence | production level of a regional unit and the danger level for every facility in the database B of the server 201 as a data table. These theft occurrence levels and risk levels can be updated automatically or manually based on the latest number of vehicle thefts. When determining the security level, refer to the data table of the database B, obtain the risk level based on the parking position and the surrounding environment, and use the previously calculated theft level plus the risk level Determine the final security level.

  In the two security level determination processes, the security level may be determined using only one of the distance and the schedule and the theft occurrence level.

  Although the embodiments of the present invention have been described above, these are merely examples, and the present invention is not limited to these embodiments, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims. Various modifications based on this are possible.
