[0033]
The navigation control unit 29 obtains the shortest route between each point based on the designated two points such as the current position and the destination and the map data, and based on the obtained route and the current position obtained from the GPS signal. Route guidance is performed while displaying a map, a route, and the like around the position on the display unit 24. At that time, when GPS signals cannot be received as when traveling inside the tunnel, route guidance is assisted by autonomous navigation based on the vehicle speed and traveling direction obtained by the vehicle speed sensor 22 and the gyro sensor 23. Can do.
[0034]
FIG. 2 is a flowchart showing a processing procedure by the navigation control unit 29. In the figure, the process from when the designation of the parking lot around the destination by the driver is accepted until the driver performs parking and the anti-theft setting is shown. In the following description, the “effective area” means an area or a parking lot where the radio wave condition with the radio wave transmission base is good and there is no problem in theft information transmission. The “invalid area” means an area or a parking lot where there is a problem in theft information transmission due to poor radio wave conditions. The “unknown area” means an area or a parking lot where it is unknown whether there is a problem with the transmission of theft information.
[0035]
When the designation of the parking lot around the destination is accepted in step 31, the designated parking lot (hereinafter referred to as “the parking lot in the past” based on the information about the parking lot of the effective area used in the past stored in the memory 27 in step 32 is accepted. It is determined whether the designated parking lot is a parking lot of an effective area used in the past or an unknown area. In addition, designation | designated reception of a parking lot can be performed by displaying and selecting the parking lot around the designated destination with the map around the destination, for example.
[0036]
If it is determined in step 32 that the parking area is an effective area used in the past, the process proceeds to step 33 to provide route guidance to the designated parking area. When the vehicle is parked in the designated parking lot, the process proceeds to step 34, and theft prevention is set. The anti-theft setting can be performed, for example, based on a user instruction or based on a detection signal indicating that the parking brake has been operated for parking. The anti-theft setting is performed by instructing the anti-theft control unit 12 to shift to the anti-theft mode. Upon receiving this instruction, the anti-theft control unit 12 shifts to an anti-theft mode, and when the vehicle is stolen due to a change in the current position of the vehicle, the theft information is sent to the security company or the driver via the communication means 11. Will be sent to the user.
[0037]
If it is determined in step 32 that the designated parking area is an unknown area, the process proceeds to step 35, where the designated parking area is a parking area in the effective area based on the information related to the parking area in the effective area stored in the memory 27. It is determined whether there is an unknown area. The information regarding the parking area of the effective area in this case includes, for example, information regarding the parking area of the effective area included in the map data or parking of the effective area acquired using the communication means 11 via the anti-theft control unit 12. Information about parking lots is applicable.
[0038]
In step 35, when it is determined that the designated parking lot is a parking lot in the effective area, the process proceeds to step 36, and the route guidance to the designated parking lot is performed as in step 33. When the vehicle is parked in the designated parking lot, the process proceeds to step 37, and the anti-theft setting is performed in the same manner as in step 34.
[0039]
In step 35, when it is determined that the designated parking lot is an unknown area, the process proceeds to step 38, and route guidance to the designated parking lot is performed. Next, in step 39, it is determined whether the parking lot where the vehicle is currently located is an effective area or an invalid area. This determination can be made based on the strength of the radio wave received by the communication unit 11 via the anti-theft control unit 12.
[0040]
If it is determined in step 39 that the area is an effective area, the process proceeds to step 40. When it is confirmed that the vehicle is parked based on a signal from the parking brake, the anti-theft setting is performed in the same manner as in step 34. . At this time, information indicating that the parking lot where the vehicle is currently located is in the effective area is added to the information regarding the parking lot of the effective area used in the past in the memory 27.
[0041]
If it is determined in step 39 that the area is an invalid area, the process proceeds to step 41 where a voice indicating that there is a problem with the transmission of theft information and the antitheft function does not operate normally, such as “This location is a radio wave. The anti-theft device will not work because the area is not reachable ”is output by the audio output unit 25. Further, in step 42, the selection of whether or not to change the parking lot is accepted.
[0042]
If it is selected in step 42 that the parking lot is not changed, the process proceeds to step 43, and the anti-theft function is not set even if the vehicle is parked.
[0043]
If it is selected in step 42 that the parking lot is to be changed, the routine proceeds to step 44, where it is determined that there is a high possibility of being an effective area, and the parking lot where the vehicle is currently located is the most. Search for a parking lot that is near or within a predetermined distance. In this case, whether or not the area is an effective area is determined by checking whether it is within a predetermined distance from the radio wave transmission base, whether the view is good, whether there is an obstacle such as a large building or mountain nearby, and the like. This can be done based on the information stored as map data or the like.
[0044]
Next, in step 45, route guidance to the searched parking lot is performed. Thereafter, the process returns to step 39, and the same processing is repeated again until parking is performed.
[0045]
According to this embodiment, when trying to park in an invalid area, the driver is notified of that fact (step 41), so the driver parks without knowing that the driver is in an invalid area. Can be prevented. In addition, when the designated parking lot is an invalid area, route guidance is made to a parking lot that is determined to be likely to be another valid area according to the driver's instruction (steps 42 and 44). 45), parking in the effective area can be easily performed.
[0046]
In addition, it is determined whether or not the area is an effective area, information on the parking area of the effective area used in the past stored in the memory 27, map data, information on the parking area of the effective area obtained by communication, actual radio wave status, etc. Therefore, parking in the effective area can be performed reliably. Moreover, since the function of the navigation system 2 is utilized, the cost of the in-vehicle antitheft device 1 can be reduced.
[0047]
In addition, this invention is not limited to the said embodiment, It can deform | transform and implement suitably. For example, in the above, when a parking lot is designated, route guidance to the designated parking lot is unconditionally performed. If the parking lot is designated, whether the parking lot is an invalid area or not Is determined based on past parking history and other information, and if it is determined to be an invalid area, the driver is informed so to prevent route guidance to the invalid area. It may be. Moreover, when it determines with it being an effective area or an unknown area in step 32 and 35, you may make it notify a driver | operator immediately of the determination result. Moreover, when it determines with it being an invalid area or an unknown area, you may enable it to specify a parking lot again.
[0048]
In the search of the parking lot in step 44, the search is performed with reference to the distance from the radio wave transmission base and the presence or absence of obstacles. Instead of this, or in addition to this, step 32 or You may make it refer to the information regarding the parking lot of the effective area memorize | stored in the memory 27 referred by 35. FIG.
[0049]
