The present invention relates to a navigation device that displays a map and a current position of a moving object, and also displays a position of another moving object.
[0002]
[Problems to be solved by the invention]
Conventionally, as this type of device, there is a device that displays the current position of the own vehicle on a map, receives other vehicle position information from another vehicle, and also displays the position of another vehicle on a map (particularly, JP-B-5-12644).
However, in the above-described device, there is a problem that only the position of another vehicle is displayed, and other information cannot be notified to each other.
[0003]
An object of the present invention is to solve the above problems.
[0004]
[Means for Solving the Problems]
According to the first aspect of the present invention, a voice of an occupant is recognized, voice data indicating the recognized voice is transmitted to another mobile body, and voice data transmitted from the other mobile body is received to perform voice recognition. The message is displayed on the display unit together with information indicating from which mobile the voice message was transmitted. When receiving voice data from another mobile, if another voice message is already displayed, the message is received. Since the voice data is stored and the voice message is switched and displayed based on the stored voice data by the call operation of the occupant, the voice messages are sequentially switched to effectively use the display space .
[0005]
Therefore, any information can be notified to another mobile using voice recognition. In this case, information transmitted from the other mobile is displayed as a voice message together with the position of the other mobile. Thus, auxiliary information on the position of another moving object can be obtained.
According to the second aspect of the present invention, since the voice message is displayed together with the reception time, the validity of the voice message can be determined.
[0006]
In the invention of claim 3, means for displaying the voice message is characterized by displaying a voice message on the display means from the oldest audio data among the audio data memorized.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows an overall configuration of an apparatus according to an embodiment of the present invention.
The navigation device according to the present embodiment includes a GPS receiver 1, a gyro 2, and a vehicle speed sensor 3 as current position detection means for detecting a current position (travel position) of a vehicle. The GPS receiver 1 receives a radio wave from an artificial satellite and outputs a signal indicating the current position of the vehicle. The gyro 2 outputs a signal according to the horizontal angular velocity of the vehicle. The vehicle speed sensor 3 outputs a signal corresponding to the running speed of the vehicle.
[0008]
The map data storage device 4 includes a storage medium such as a CDROM for storing map data, and outputs the map data to the control device 6. The input device 5 is operated by an occupant and outputs an input signal necessary for navigation.
The control device 6 includes computer means such as a microcomputer, and has a current position obtained by a self-contained navigation based on signals from the gyro 2 and the vehicle speed sensor 3 and a current position obtained from a signal from the GPS receiver 1. Based on the above, the current position of the vehicle is accurately detected, the map data is read from the map data storage device 4, and the display device 7 displays the current position of the vehicle and a road map. When a destination is set by operating the input device 5, a destination route from the current position to the destination is set, the route is highlighted on the display device 7, and the sound generation device 8 is set. , Guidance information for route guidance is generated by voice.
[0009]
The communication device 9 transmits position information such as the current position obtained by the control device 6 to another vehicle, and receives other vehicle position information transmitted from the other vehicle. In this case, communication between the own vehicle and another vehicle is performed by specifying the vehicle code. The control device 6 causes the display device 7 to display the other vehicle position based on the received other vehicle position information. That is, the other vehicle also has a navigation device having the same configuration as that shown in FIG. .
[0010]
The voice recognition device 10 recognizes the voice of the occupant and outputs the voice to the control device 6 as voice data (data indicating the recognized voice). When receiving the voice data from the voice recognition device 10, the control device 6 causes the communication device 9 to transmit the voice data as auxiliary information of the own vehicle position to another vehicle. When the communication device 9 receives voice data from another vehicle, the control device 6 sounds the buzzer 11 and causes the display device 7 to display a voice message based on the received voice data.
[0011]
The operation of the above configuration will be described.
The control device 6 repeatedly executes the processing shown in FIG. 2 when an operation for performing the group traveling is performed on the input device 5 in the navigation control described above.
First, in step 100, control processing similar to the above-described navigation control is performed. That is, the current position of the vehicle is detected based on the signals from the gyro 2 and the vehicle speed sensor 3 and the signal from the GPS receiver 1, and the map data is read out from the map data storage device 4. Display the location and road map. When a destination is set by operating the input device 5, a destination route is set, the route is highlighted on the display device 7, and a route guidance is provided from the voice generating device 8. Generate guidance information by voice. Thereafter, the navigation process of step 100 is repeatedly executed together with the transmission process of step 200, the reception of step 300, and the other vehicle position display process.
[0012]
FIG. 3 shows a specific process of step 200. First, it is determined whether it is necessary to transmit own vehicle position information to another vehicle (step 201). For example, it is assumed that it is necessary to transmit the own vehicle position information when the traveling direction of the own vehicle changes significantly. When it becomes necessary to transmit the own vehicle position information to another vehicle, the communication device 9 causes the other vehicle to transmit the own vehicle position information (step 203). Also, when there is a transmission request from another vehicle, the communication device 9 causes the other vehicle to transmit own vehicle position information (steps 202 → 203).
[0013]
When it is determined that the voice data has been output from the voice recognition device 10 (step 204), the voice data is transmitted from the transmission device 9 to another vehicle (step 205).
FIG. 4 shows a specific process of step 300. First, it is determined whether or not the communication device 9 has received other vehicle position information from another vehicle (step 301). When the other device position information is received, the other vehicle position is displayed on the display device 7 based on the other vehicle position information. (Step 305). FIG. 5A shows an example of the display. A is a vehicle position mark, and B is another vehicle position mark. When the other vehicle position is located outside the area of the map displayed on the display device 7, the other vehicle position mark B is displayed in a direction in which the other vehicle position exists outside the area.
[0014]
Further, even when the other vehicle position information is not received from another vehicle, when it is determined that a predetermined time or more has elapsed since the previous reception of the other vehicle position information (step 303), a transmission request is made to the other vehicle, and the other vehicle is transmitted. The other vehicle position information is received (step 303), and the other vehicle position is displayed on the display device 7 (step 305).
When the communication device 9 determines that voice data has been received from another vehicle (step 305), the buzzer 11 first generates a buzzer sound for a certain period of time (step 306). Next, it is determined whether a voice message is being displayed on the display device 7 at the time of this reception (step 307). When the voice message is not displayed, the voice message is displayed on the display device 7 by the received voice data (step 308). For example, when another vehicle is in the parking lot and receives voice data of “third from the back of the parking position” from the other vehicle, a voice message is displayed as shown in FIG. The displayed voice message is automatically deleted after a predetermined time, or is deleted by an occupant's deletion operation.
[0015]
If a voice message is displayed when receiving voice data, the received voice data is stored together with the reception time (step 309).
Thereafter, if it is determined that a call operation (operation for displaying a voice message) by the occupant has been performed on the input device 5 (step 310), the voice message is received using the earliest received voice data among the stored voice data. The display is switched and displayed on the display device 7 together with the time (step 311).
[0016]
Therefore, according to the above embodiment, the group traveling is enabled by displaying the position of the other vehicle, and the voice message from the other vehicle is displayed as the auxiliary information, so that the auxiliary information can be used more effectively. Group driving can be performed.
Also, when another voice message is already displayed when receiving voice data from another vehicle, the received voice data is stored, and a voice message based on the stored voice data is displayed by an occupant's calling operation. Therefore, the display space can be effectively used by switching and displaying the voice message. If the display space does not matter, a voice message may be displayed in parallel each time it is received.
[0017]
In the above-described embodiment, one other vehicle has been described. However, the position of each other vehicle may be displayed for a plurality of other vehicles. Preferably, a voice message is displayed along with information indicating whether the message has been transmitted from the Internet.
Further, the present invention is not limited to vehicles, but can be applied to other moving objects such as ships.
