And the vehicle information acquisition means 12 outputs the information regarding the direction change of the vehicle from the direction detection part 12A, and the information regarding the speed and travel distance from the vehicle speed detection part 12B to the control part 24 as travel information. Further, the parking brake detection unit 12C of the vehicle information acquisition unit 12 detects that the parking brake of the vehicle has been operated and transmits this to the control unit 24.

  As the direction detection unit 12A of the vehicle information acquisition unit 12, a known angular velocity sensor such as a gyro sensor is used. In particular, a vibration gyro sensor is preferably used from the viewpoint of price. Further, as the vehicle speed detection unit 12B of the vehicle information acquisition means 12, a vehicle speed pulse acquisition unit, a vehicle speedometer wire attached to a vehicle speedometer and its speed and travel distance from its rotation, and a vehicle tire are installed. For example, a well-known vehicle speed sensor can be used such as one that acquires the speed and travel distance by rotating the tire. The vehicle information acquisition unit 12 may be a 3D gyro that is a combination of a vibration gyro sensor, an acceleration sensor, and a vehicle speed sensor.

  As the parking brake detection unit 12C of the vehicle information acquisition means 12, it is preferable to use a connection terminal of a parking brake switch provided in advance in the vehicle. However, the parking brake detection unit 12C is connected to a parking brake drive system, operation system or control system and turned on. -You may make it detect OFF.

  As the map data section 14, it is preferable to use an optical recording medium such as a DVD on which predetermined map data is recorded in advance, a recording medium such as a hard disk or a nonvolatile memory. Moreover, if it is set as the structure which acquires map data via a radio | wireless from a base station etc., map data can be updated completely or partially without going through a recording medium.

  As the advertisement data unit 16, a recording medium in which predetermined advertisement data is recorded in advance may be used as the advertisement data unit 16, or advertisement data is also recorded in a recording medium in which map data is recorded, and this is used as the advertisement data unit 16. Also good. In this case, if the selling price of the map data is reduced by the advertisement fee of the recorded advertisement data, the user can purchase the latest map data at a low price, and the advertiser can update the latest price each time. Advertisement information can be provided. Furthermore, if the advertisement data is obtained wirelessly from a base station, an information center or the like, the advertisement data can be updated as needed, and the user can always obtain new advertisement information. Further, when the vehicle enters an arbitrary area, the recording capacity required for the advertisement data unit 16 can be reduced if the advertisement data related to the area is obtained and updated.

  The input unit 18 inputs a destination, a search method, and other instruction commands to the navigation device 50 to the navigation device 50, and uses a well-known input device such as a voice input device or a button input device including a touch panel. Can do.

  The route guidance means 20 guides and guides a user (driver) to drive the vehicle along a set route, and displays a color liquid crystal or an organic EL display capable of displaying a vehicle position and a map. And a voice output for performing route guidance by voice are generally used. In addition to the route guidance, the route guidance means 20 can output the advertisement information on the screen and / or by sound when a predetermined condition described later is satisfied.

  Next, the operation of the navigation device according to the present invention will be described. Note that the navigation device 50 according to the present invention is characterized by the advertisement information providing method, and thus detailed description of operations not directly related to the present invention is omitted.

  First, the navigation device 50 is activated. Then, the position information acquisition means 10 receives radio waves from a plurality of (usually three or four) GPS satellites and acquires the position and distance of each GPS satellite. Then, the current position of the vehicle on which the navigation device 50 is mounted is specified from the positions and distances of the plurality of GPS satellites, and this is output to the control unit 24 as vehicle position information. The control unit 24 performs a map matching process between the position information from the position information acquisition unit 10 and the map data stored in the map data unit 14, and displays a map screen including the vehicle position on the display unit of the route guidance unit 20. .

  When the vehicle travels, the direction detection unit 12A of the vehicle information acquisition unit 12 senses a change in the vehicle direction due to a curve or a left / right turn. Moreover, the vehicle speed detection part 12B of the vehicle information acquisition means 12 acquires the information regarding the speed and the travel distance of a vehicle. And the vehicle information acquisition means 12 outputs the information from these direction detection parts 12A and the vehicle speed detection part 12B to the control part 24 as driving information. In parallel with this, the position information from the position information acquisition means 10 is also input to the control unit 24 as needed.

  The control unit 24 performs a map matching process from the position information from the position information acquisition unit 10, the travel information from the vehicle information acquisition unit 12, and the map data stored in the map data unit 14, so that the route guidance unit 20 The screen display is changed to follow the progress of the vehicle. These processes are continuously performed as needed while the navigation device 50 is in operation.

  When making the navigation device 50 perform route guidance to the destination, the user first inputs the destination to the route search unit 26 of the control unit 24 via the input unit 18 (FIG. 2, step S100).

  When the destination is input to the route search unit 26, the route search unit 26 specifies the destination from the map data stored in the map data unit 14, and searches the route from the current position to the destination according to a predetermined algorithm. (Step S101). At this time, if the user inputs conditions such as whether to use a relay point or a toll road on the way, the route search unit 26 searches for a route that satisfies the conditions.

  While the route search unit 26 searches for a route, the navigation device 50 according to the present invention displays predetermined advertisement information stored in the advertisement data unit 16 on the screen display of the route guidance means 20 and / or voice output. Provide (step S102). The provision of the advertisement information is continuously performed during the route search operation, and is stopped when the route search operation ends (step S103). Thereafter, the control unit 24 of the navigation device 50 performs the following operation process (step S104).

  Note that a general navigation device cannot input a destination while the vehicle is traveling from the viewpoint of traffic safety. Therefore, it is necessary to input the destination when the vehicle is stopped, and the vehicle is often stopped during the subsequent route search operation. Therefore, by providing the advertisement information during the waiting time during the route search operation, the user can concentrate on viewing the advertisement information without being distracted by driving. Furthermore, if the tourist guide and store information in the vicinity of the input destination and its route are provided as advertisement information, the user is more interested than being provided with the advertisement information while driving the vehicle, and has a very high advertising effect. Obtainable.

  When the route search operation is completed and a route to the destination is set, the navigation device 50 starts a guidance and guidance operation so that the user can drive the vehicle along the route. The route may be set by the route search unit 26 outputting a plurality of routes as candidates and the user selecting them.

  For example, when the vehicle reaches a predetermined guidance point such as an intersection, the route guidance means 20 performs guidance guidance such as turning right, turning left, or going straight on the screen and / or by voice. . Further, when the vehicle is traveling off the set route, guidance guidance for returning to the original route, or new route setting is performed and guidance guidance is performed along the guidance.

  Here, when the vehicle is stopped by a stop signal, a break or the like and the parking brake is operated, the parking brake detection unit 12C of the vehicle information acquisition unit 12 detects this and the control unit detects that the parking brake has been operated. 24. When the control unit 24 confirms the operation of the parking brake (FIG. 3, step S200), the control unit 24 provides predetermined advertisement information stored in the advertisement data unit 16 on the screen display of the route guidance means 20 and / or voice output (both) Step S201). The provision of this advertisement information is continued during the parking brake operation, and stops when the parking brake operation is released (step S202). Thereafter, the control unit 24 of the navigation device 50 returns to a predetermined operation (step S203). The advertisement information providing operation described above may be performed not only during the guidance and guidance operation but also whenever the parking brake is operated while the navigation device 50 is in operation.

  Since the parking brake is operated when the vehicle is stopped, providing advertisement information during the operation of the parking brake allows the user to watch the advertisement information without being distracted by driving. In addition, it is possible to obtain a higher advertising effect than during driving.

  Also, if the user inadvertently keeps the parking brake operating and keeps the vehicle running, the advertising information will continue to flow, so the user detects the abnormality and releases the parking brake. be able to. Even if the vehicle continues to run with the parking brake being operated for some reason, the provision of the advertisement information is temporarily stopped when the vehicle reaches a predetermined guidance point during the guidance guidance operation by the navigation device 50. Guide guidance is given priority.

  Also, when the vehicle travels on the road, it stops for a long time without operating the parking brake, for example, due to traffic jams, waiting for traffic lights, waiting for the train to pass, etc. Or moving at a low speed, such as frequently stopping and running at a low speed. At this time, the travel information output from the vehicle information acquisition means 12 to the control unit 24 also reflects this low speed movement. When recognizing that the vehicle is moving at a low speed from the travel information of the vehicle information acquisition means 12 (FIG. 4, step S300), the control unit 24 determines whether or not the low-speed movement has continued for a predetermined time or more. (Step S301) When it continues, the predetermined advertisement information stored in the advertisement data section 16 is provided on the screen display of the route guidance means 20 and / or voice output (Step S304). However, when the navigation device 50 is in the guidance guidance operation and the vehicle reaches a predetermined guidance point, guidance guidance is given priority (steps S302 and S303).

  The advertisement information is continuously provided until the low-speed movement of the vehicle is completed, and is stopped when the low-speed movement is completed (step S305). Thereafter, the control unit 24 of the navigation device 50 returns to a predetermined operation (step S306). The advertisement information providing operation may be performed not only during the guidance and guidance operation but also whenever the above conditions are satisfied while the navigation device 50 is in operation.

  During the low-speed movement of the vehicle as described above, it is conceivable that the user views the advertisement information for a change of mood, and a high advertisement effect can be obtained. In addition, the threshold regarding the time during the low speed movement which judges whether advertisement information is provided, and the speed of the vehicle considered as low speed movement can be set arbitrarily. Furthermore, by providing a plurality of thresholds in stages, the advertisement information to be provided can be changed, for example, a resting facility if the duration of low-speed movement is several hours or more, and an accommodation facility if it is more than a dozen hours or more. In this case, a higher advertising effect can be obtained.

  From the above, according to the navigation device 50 of the present invention, the advertisement information is provided during the route search operation of the route search unit, the parking brake operation of the vehicle, and the low-speed movement of the vehicle that continues for a predetermined time or more. Therefore, the user does not feel discomfort due to frequent advertisement information provision. In addition, while the parking brake is in operation, the route search operation is often performed while the vehicle is stopped, and during low-speed movement, the frequency and time of the vehicle stopping are long, so the user can wait for these waiting times. The advertisement information can be viewed in a relatively concentrated state. Therefore, it is possible to obtain a higher advertising effect than when advertising information is provided during driving.

  The advertisement information to be provided is preferably provided according to the traveling of the vehicle, although it is preferable to provide information related to the location where the vehicle is traveling, the set destination and the periphery of the route. In addition, advertisement information to be provided may be selected and provided according to time, vehicle continuous travel time, vehicle travel distance, and the like. For example, advertising information such as eating and drinking facilities at breakfast, lunch and dinner times, advertising information such as accommodations in the evening, and advertising information such as resting facilities when the vehicle continues running for a long time If the travel distance of the vehicle is a long distance, advertisement information such as a refueling facility can be provided more efficiently.

  In this example, the hybrid navigation type navigation device 50 has been described as an example. However, the present invention can also be applied to, for example, a portable navigation device that operates only by GPS navigation. Detection of low-speed movement in this case may be performed based on the time change of the position information obtained by the position information acquisition means 10. In this example, the route guidance unit 20 is provided with a display unit and a voice output. However, the route guidance unit 20 may be only a voice output, and the present invention departs from the gist of the present invention. It is possible to change and implement within the range not to be. Alternatively, the navigation device 50 may be configured as another device without incorporating the route guidance means 20 and output to the device. Similarly, a configuration may be adopted in which the navigation device 50 does not include the input unit 18 but is provided as another device, and input is performed by the device.
