Has been. Each program that functions as the map information acquisition unit 13, the position recognition unit 14, the determination unit 15, and the determination unit 16 is written in advance in a memory (not shown) of the control unit 10.

  The inclination sensor 11 is a sensor capable of detecting the inclination of the vehicle 30 based on a change in the horizontal acceleration component generated in the vehicle 30 and sending angle information θ based on the inclination. For example, the inclination sensor 11 is a G sensor (acceleration sensor). ) Corresponds to this. In the case of this embodiment, for example, the inclination sensor 11 is provided in the lower part of the center console (not shown) near the intersection of diagonal lines C1 and C2 connecting the centers of the tires 32 of the vehicle 30.

The coordinate information acquisition unit 12 has a function of acquiring the current position of the vehicle 30 as coordinate information P from a GPS sensor 21 included in the navigation device 20 described later.
The map information acquisition unit 13 has a function of acquiring the map information M from the map database 22 included in the navigation device 20.

Based on the map information M acquired by the map information acquisition unit 13 and the coordinate information P acquired by the coordinate information acquisition unit 12, the position recognition unit 14 determines the position of the vehicle 30 on the map created by the map information M. The function of recognizing the position of the vehicle 30 is provided.
The determination unit 15 has a function of determining whether or not the position of the vehicle 30 on the map recognized by the position recognition unit 14 is a predetermined position or range.

According to this configuration, since the map information acquisition unit 13 can acquire the map information M from the map database 22 of the navigation device 20, there is no need to separately prepare a database dedicated to map information, which is advantageous in terms of cost. is there.

(Vehicle theft determination processing by the vehicle theft determination device)
Next, vehicle theft determination processing by the vehicle theft determination device will be described with reference to FIG. This vehicle theft determination process is executed by the control unit 10 shown in FIG. 1 and is repeatedly performed at a predetermined time interval after the ignition switch of the vehicle 30 is turned off, for example.

  First, in this vehicle theft determination process, the longitude and latitude of the current position of the vehicle 30 sent from the GPS sensor 21 provided in the navigation device 20 in step S101 are acquired as coordinate information P. This step S101 is performed by the coordinate information acquisition unit 12.

  Next, the process proceeds to step S103, and the map information M is acquired from the map database 22 provided in the navigation device 20 by the step S103. This step S103 is performed by the map information acquisition unit 13.

  Subsequently, based on the map information M acquired by the map information acquisition unit 13 in step S105 and the coordinate information P acquired by the coordinate information acquisition unit 12, the current position of the vehicle 30 is created by the map information M. The attribute information N is set by recognizing the position or range of the vehicle 30 on the map. This step S105 is performed by the position recognition unit 14. For example, a virtual map is created in a memory space (not shown) that constitutes the control unit 10 by the map information M, and the coordinate information P and the map information M are By performing map matching, it is recognized as the position or range of the vehicle 30 on the map.

  Subsequently, in steps S107 and S109, it is determined whether or not the current position of the vehicle 30 on the map is within a predetermined position or range. Specifically, for example, when a vehicle is transported by a pallet-type multistory parking lot or a ferry, it is determined whether or not the current position of the vehicle 30 is on the sea. Steps S107 and S109 are performed by the determination unit 15.

  First, in step S107, it is determined whether the vehicle 30 is on the water (N = 1) or not (N ≠ 1). If it is determined that the vehicle 30 is not on the water (N ≠ 1) (S107: No), then, in step S109, it is determined whether the vehicle 30 is in a multilevel parking lot (N = 2) or not (N ≠ 2). To do. If it is determined that the vehicle 30 is not in the multistory parking lot (N ≠ 2) (S109: No), the vehicle 30 is in a position or range other than on the water and in the multistory parking lot (N = 3). It is determined that it is other than “predetermined position or range”.

  If it is determined in step S109 that the vehicle 30 is not in the multilevel parking lot (S109: No), the angle information θ sent from the tilt sensor 11 is acquired in step S111, and the angle information θ is preset in step S113. It is determined whether or not the threshold value θs is exceeded (θ> θs).

  If it is determined that the angle information θ exceeds the threshold value θs (S113: Yes), the vehicle 30 is outside the water and a multilevel parking lot (predetermined position or range), and the angle information θ is equal to the threshold value θs. Therefore, it is determined that the vehicle 30 has been stolen. The above S111 and S113 are performed by the determination unit 16. In this case (S113: Yes), an alarm is issued in the subsequent step S115, and the vehicle theft determination process is terminated. This step S115 is performed by the alarm unit 35.

  On the other hand, when it is determined that the vehicle 30 is on the water or in a multilevel parking lot (predetermined position or range) (S107: Yes or S109: Yes), this vehicle theft determination is not applicable because it does not correspond to theft The process ends.

  Further, when the angle information θ does not exceed the threshold value θs (S113: No), for example, when a third party lifts the front wheel when carrying out the vehicle without permission using a tow truck or the like. In addition, an abnormal inclination of the vehicle is not detected. Therefore, since it is determined that the vehicle 30 is not stolen, the vehicle theft determination process is terminated without issuing an alarm.

[Effect of the first embodiment]
As described above, according to the invention of the first embodiment, when the vehicle 30 is on the water or in a pallet type multistory parking lot, even if the vehicle 30 is inclined, it does not result from an event accompanying theft. Therefore, since the determination unit 16 does not determine whether or not the vehicle 30 has been stolen, there is no possibility of erroneously detecting that the vehicle 30 has been stolen. Further, since the user does not need to set the vehicle theft determination device 1 to the “three-dimensional parking mode” as in the prior art, the vehicle is stolen because the user forgot to set the “three-dimensional parking mode”. There is no risk of false detection.
That is, the vehicle theft determination device 1 that prevents erroneous detection of theft of the vehicle 30 can be realized.
Furthermore, since the alarm unit 35 can notify the user and the vehicle surroundings of the vehicle theft, a vehicle theft prevention device that prevents erroneous detection of the vehicle theft by combining with the vehicle theft determination device 1 is realized. can do.

Second Embodiment
2nd Embodiment of the vehicle theft determination apparatus which concerns on this invention is described with reference to figures. In the vehicle theft determination device of the second embodiment, the map information M ′ does not have a parking lot attribute for distinguishing between a pallet-type multistory parking lot and other self-propelled parking lots, and movement described later. The sensor 17 is further different from the vehicle theft determination device of the first embodiment. For this reason, about the structure similar to 1st Embodiment, while using the same code | symbol, description is abbreviate | omitted.
FIG. 4 is a block diagram showing a configuration of the vehicle theft determination device of the second embodiment. FIG. 5 is a flowchart illustrating a vehicle theft determination process performed by the vehicle theft determination device according to the second embodiment.

(Configuration of vehicle theft determination device)
As shown in FIG. 4, the vehicle theft determination device 2 according to the second embodiment further includes a movement sensor 17 in addition to the vehicle theft determination device 1 according to the first embodiment.

  The movement sensor 17 is a sensor capable of detecting an upward or downward movement of the vehicle 30 based on a change in acceleration generated in the vehicle 30 and sending a movement signal H based on the movement. It is electrically connected to the input port. The movement sensor 17 is provided adjacent to the inclination sensor 11, and based on the movement information H sent from the movement sensor 17, the determination unit 15 determines that the position of the vehicle 30 on the map is a pallet-type multistory parking lot. Determine whether or not.

  The map database 23 stores map information M ′. This map information M ′ does not have a parking lot attribute for distinguishing between a pallet-type multistory parking lot and other self-propelled parking lots, and the pallet-type multistory parking lot and other self-propelled types It is the same as the map information M of the first embodiment except that the parking lot including both parking lots is “N = 2”.

(Vehicle theft determination processing by the vehicle theft determination device)
Next, vehicle theft determination processing by the vehicle theft determination device will be described with reference to FIG. In addition, since S101-S107 and S111-S115 are the same processes as 1st Embodiment, description is abbreviate | omitted. The following S201 to S205 are performed by the determination unit 15.

  Subsequent to step S107, it is determined in step S201 whether the vehicle 30 is in a parking lot (N = 2) or not (N ≠ 2). If it is determined that the vehicle 30 is in the parking lot (N = 2) (S201: Yes), the movement signal H sent from the movement sensor 17 is acquired in step S203, and the movement signal H is preset in step S205. It is determined whether the threshold value Hs is not exceeded (H ≦ Hs).

  When the movement signal H does not exceed the threshold value Hs (H ≦ Hs), the vehicle 30 is parked in the self-propelled parking lot because it does not move upward or downward. Therefore, if it is determined that the movement signal H does not exceed the threshold value Hs (S205: Yes), the vehicle 30 is parked in the self-propelled parking lot, so that it is outside the “predetermined position or range”. As a result, the process proceeds to step S111. On the other hand, if it is determined in step S201 that the vehicle 30 is not in the parking lot (N ≠ 2) (S201: No), the process proceeds to step S111.

  On the other hand, when it is determined that the movement signal H exceeds the threshold value Hs (S205: No), the vehicle 30 is accompanied by movement upward or downward, so that the pallet-type multistory parking lot is used. It is determined that the vehicle is parked at the “predetermined position or range”, and the vehicle theft determination process is terminated because it does not correspond to the theft.

[Effects of Second Embodiment]
Since the vehicle theft determination device 1 includes a movement sensor 17 that can detect movement of the vehicle 30 upward or downward and send out movement information H based on the movement, the vehicle theft 30 can be moved upward or downward. Movement can be detected.
Therefore, even when the map information M ′ does not have a parking lot attribute that can distinguish a pallet-type multistory parking lot from other self-propelled parking lots, the vehicle 30 is in the parking lot, When the upward or downward movement is detected, the determination unit 15 can determine that the vehicle 30 is parked in the pallet type multistory parking lot. Further, when the vehicle 30 is in the parking lot and the upward or downward movement of the vehicle 30 is not detected, the determination unit 15 can determine that the vehicle 30 is parked in the self-propelled parking lot.
