In addition, the information generated by the transmission information generation unit 45 includes information that instructs the stop of the vibration motor 24.

[Action]
An example of the guidance process using the small receiving terminal 20 according to the present embodiment as described above will be described with reference to the explanatory diagram of FIG. 2 and the flowcharts of FIGS. 3 shows processing in the navigation device N, and FIG. 4 shows processing in the small receiving terminal 20. First, the user places the small receiving terminal 20 in a place where vibration such as a breast pocket can be detected. When the user operates the input / output unit 10 to set a destination and instruct a route search, the route setting unit 42 calculates a route based on the coordinates of the current location. When the user starts traveling of the vehicle, route guidance is performed by the map display control unit 43 and the guidance control unit 44 based on the calculated route (step 301).

  During such route guidance, when the distance from the current position to the intersection to be guided reaches a preset distance (step 302), it is judged from the set route, and the intersection goes straight. If it is necessary to turn right or left instead of (step 303), information about the distance and information about right / left turn are generated by the transmission information generation unit 45 and transmitted from the RF transmission / reception unit 15 (step). 304).

  On the other hand, in the small receiving terminal 20 that has received this (step 401), the information received by the control unit 22 is analyzed based on the setting in the setting unit 23, and is not 10 meters before the intersection (step 402). ) When making a right turn (step 403), the vibration motor 24 is operated once (step 404). When making a left turn (step 403), the vibration motor 24 is operated twice (step 405).

  Thereby, the user senses any of the above vibrations at short intervals as the distance to the intersection becomes shorter, for example, 700 m before, 300 m before, 100 m before, 50 m before, 30 m before the intersection, You can know whether you should turn right or left at the previous intersection. Further, the information received by the control unit 22 is analyzed, and when it is 10 meters before the intersection (step 402), the control unit 22 continuously operates the vibration motor 24 (step 406). Thereby, the user can determine that it is immediately before entering the intersection.

  Thereafter, in the navigation device N, when it is determined that the vehicle has entered the intersection and moved a predetermined distance after the right / left turn is completed (step 305), the transmission information generation unit 45 instructs to stop the vibration motor 24. Information to be generated is transmitted from the RF transceiver 15 (step 306).

  On the other hand, in the small receiving terminal 20 that has received this (step 407), the control unit 22 stops the vibration motor 24 (step 409). In addition, for example, when stopping by a signal or the like before the intersection, the stop signal is not transmitted for a long time, and the vibration motor 24 continues to rotate. Therefore, the user presses the operation button 25 of the small receiving terminal 20. The vibration motor 24 can also be stopped (steps 408 and 409).

[effect]
According to the present embodiment as described above, even if the voice guidance is difficult to hear or difficult to hear, information on the distance to the intersection and the right / left turn can be obtained by the vibration of the small receiving terminal 20, The convenience of the navigation device is improved. In particular, as the current position approaches the intersection, the vibration interval becomes shorter, so that the approach to the intersection can be intuitively known.

In addition, this invention is not limited to the said embodiment, Other embodiments which are illustrated below are included. For example, at the time of single-shot information such as VICS update, the user can be notified of information provision by operating the vibration motor three times based on the information transmitted from the navigation device side. As a result, the user can know the information provision content in a timely manner by looking at the screen displayed on the display device of the car navigation device, and can obtain more guidance information.

  Thus, the information notified to the user from the navigation device via the small receiving terminal is free, and is not limited to the information regarding the right / left turn. That is, the variation of the vibration mode can be increased, and not only the right / left turn but also the advancement in the straight direction and the diagonal direction, various information that should be noted in advance, and the like can be distinguished and notified. The points to be guided are not limited to intersections, and any point on the map (including facilities and natural objects) can be targeted. Thus, for example, when a certain distance is approached to a certain facility, it is notified by one or more predetermined number of vibrations, and as it gets closer, the predetermined facility is intermittently repeated at short intervals, thereby becoming the target facility. The approach to can be notified.

  The setting of which distance to notify of the distance to the point and the setting of the vibration mode by the vibration motor are not limited to the above embodiment. For example, the distance to the intersection may be notified at equal intervals. When the number of operations of the vibration motor is plural, the setting of the operation time and stop interval for each vibration is also free. You may set not with the frequency | count of operation but with the rotation speed and the continuous operation time length. The rotational speed of the motor can be made variable so that the vibration level can be changed, and the information to be notified can be distinguished based on the strength level.

  Moreover, as shown in FIG. 5, the small receiving terminal 20 can also be integrated with the keyless entry system of a motor vehicle. In other words, by embedding this embodiment in the key-side unit used in the keyless entry system, you can use various functions such as unlocking, engine starting, and navigation simply by putting this in your chest pocket. Can be convenient.

  Moreover, the form of a small receiving terminal can also be devised. For example, as shown in FIG. 6, a pair of small receiving terminals 20 are provided on the left and right sides of the headset, and the left is vibrated when turning left, and the right is vibrated when turning right. You can also. As shown in FIG. 7, this can also be realized by incorporating a small receiving terminal 20 in each of a pair of separable units and putting them in left and right pockets. When such a pair of small receiving terminals 20 is used, a right or left turn can be notified by simple vibration.

  Various settings as described above may be performed on the recording medium on the navigation device side or on the recording medium on the small receiving terminal side. A small receiving terminal equipped with a USB connector and connected to a navigation device, personal computer, etc., or by wirelessly transmitting / receiving information to / from the navigation device, personal computer, etc. It can also be set as the structure which can change the setting of a terminal. The antenna can also be reduced in size by being configured with a pattern on a printed wiring board, but sensitivity can also be increased using a coil exposed to the outside. Any wireless frequency band, modulation, and data transmission method used in the present invention can be used at present and in the future.
