Description

  The present invention relates to a vehicle navigation apparatus that guides a route to a destination, and more particularly to a vehicle navigation apparatus that can control the operation of a child proof mechanism.

  As the vehicle travels, the current position is detected by GPS (Global Positioning System), etc., and the current position is displayed on a display device together with a road map, and an appropriate route from the starting point to the destination The vehicle navigation device that guides the vehicle using a display device, a voice output device, or the like contributes to efficient and safe driving for the user.

  In recent years, there are some vehicle navigation devices that improve user convenience in cooperation with other in-vehicle devices. For example, when there are many crimes, accidents, etc. and the user cannot go to the destination unless he / she passes through the avoidance area, the door lock device is driven when the door is in the avoidance area. Has been devised (see Patent Document 1).

  In addition, a child proof mechanism that prevents the elderly and children from accidentally opening the door has been widely used. The child proof mechanism cannot open the door from the inside of the vehicle, but can open the door from the outside of the vehicle. For example, an automatic door lock device for a vehicle has been devised in which a door is automatically locked by a child proof mechanism when the vehicle is stopped (see Patent Document 2).

  On motorway roads such as highways, there is a possibility of being released outside the vehicle when the door is opened. Also, in the service area or the parking area, since the vehicle is traveling at a relatively high speed, it is not desirable to open the door. With the above configuration, it is possible to prevent an elderly person / child from accidentally opening the door while the vehicle is running.

  In addition, the child proof mechanism operation control means in the vehicle navigation apparatus of the present invention can be configured to operate the child proof mechanism when the current position of the vehicle is in a parking lot.

It can also be configured to be set as a door.

  It does not make sense to activate the child proof mechanism of the seat door where no occupant is sitting. With the above-described configuration, it is possible to automatically set the child proof mechanism to operate only the door that is necessary.

  In addition, the vehicle navigation device of the present invention can also be configured to include an operation release unit that automatically releases the operation of the child proof mechanism when a predetermined condition is satisfied.

Next, in order to check whether or not the seat is a target for detecting an occupant, the detection target setting information stored in advance in the database 21d or the like is referred to (S32). For example, in the default state, the detection target setting information is set so that occupant detection is performed only for the rear seat. It is also possible to change the setting information by a user operation. However, not all seats can be detected.

  If it is a seat to be detected by the occupant (S33: Yes), it is determined whether or not the occupant is seated in the seat. If the occupant is seated (S34: Yes), the nearest door of the seat Is set so that the child proof mechanism operates (S35). Then, if there is another seat for which an occupant is to be detected (S36: Yes), the processes after step S34 are repeated.

That is, a command signal for not operating the child proof mechanism is sent from the navigation device 100 to the door lock ECU 400 via the in-vehicle LAN 27. Receiving the command signal, the door lock ECU 400 sends a command to each actuator 111 from the arithmetic processing unit 414 to release the child proof mechanism so that the door can be opened from the inside of the vehicle.

(Child proof mechanism operation control process 2)
Another example of the child proof mechanism operation control process will be described with reference to FIG.

Other in-vehicle devices acquire airbag operation information as necessary, and perform control based on the information.

  Next, when it is determined that the airbag is activated based on the acquired airbag activation information (S112: Yes), the child proof mechanism is not activated (S113). The operation release of the child proof mechanism is the same as in FIG. If it is not determined that the airbag has been activated (S112: No), child proof mechanism activation processing (described later) for activating the child proof mechanism may be executed.

  The airbag ECU 300 uses a well-known acceleration sensor (not shown) to determine that a collision occurs when the value of the acceleration sensor exceeds a predetermined value and activates an airbag (not shown) ( In this configuration, when the acceleration information is acquired from the acceleration sensor and the acceleration information exceeds a predetermined acceleration threshold value, the child proof mechanism is not operated.

For example, when the vehicle speed falls below a predetermined threshold such as 5 km / h and it is determined that the vehicle 101 is stopped (S152: Yes), image information captured by the camera group 32 is acquired (S153). The camera group 32 may always shoot or may shoot only when the vehicle 101 is stopped.

Next, reference is made to the setting information about the individual door in the operating door setting information (S132). When the door is set as the child proof mechanism operation target (S133: Yes), the child proof mechanism of the door is operated (S134).

  That is, the navigation device 100 sends a command signal for operating the child proof mechanism by designating the door position to the door lock ECU 400 via the in-vehicle LAN 27. Upon receiving the command signal, the door lock ECU 400 sends a command from the arithmetic processing unit 414 to each actuator 111 to operate the child proof mechanism 110 of the corresponding door so that the door cannot be opened from the inside of the vehicle.

  And the process from step S132 to S134 is performed about all the seats (S135).

  In addition, any one of the child proof mechanism operation control processes 1 to 5 described above may be used, or two or more of them may be used in combination.

  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.
