FIG. 7 is a characteristic diagram for explaining the operation of the receiving device.

In FIG. 1, reference numeral 1 denotes a broadcasting device including a text multiplex broadcasting device for FM broadcasting.
Is a receiving device 2 for receiving and displaying character information, a transmitting device 3 for wirelessly transmitting information to the receiving device 2, and an input device 5 for inputting traffic information and the like to the transmitting device 3 through a telephone line 4 or the like. It has.

The transmitting device 3 receives, for example, data in a format shown in FIG. 2 from the input device 5 as character information. The data includes a header 8 for designating the source and characteristics of the information. And the body 9 of the information.

The receiving device 2 includes a display 6 for displaying the received character information. The display 6 displays the header 8 and the text 9 in three lines. The information display page, display position, display time, and the like can be arbitrarily changed.

The receiving device 2 includes an operation function key 11, a direction key (cursor key) 12 for moving a cursor, etc., an operation confirmation key 13, and a speaker 14 for outputting an audio signal. ing.

The receiving device 2 includes an antenna 16 and a tuner 18 as character information receiving means for receiving a text broadcast signal transmitted from the transmitting device 3, and a demodulation for demodulating FM multiplexed data from the received signal. A section 19 and a CPU (sound output control means) 20 for controlling reception by the tuner 18 and controlling output of character information by sound, and the like.

The CPU 20 has a storage device RO
M23 and RAM 24 are connected, and predetermined data is input and output. In addition, the voice conversion unit 2 is a voice conversion unit that converts the received character information into a voice signal.
The audio signal is amplified by an amplifier 27 and output from a speaker (audio output means) 14.

The CPU 20 receives the running speed of the vehicle from the vehicle speed sensor 32 and the inter-vehicle distance sensor 33 provided outside via I / Fs 30 and 31 as inter-vehicle speed input means and inter-vehicle distance input means. The inter-vehicle distance to the car is input. When the inter-vehicle distance to the preceding vehicle becomes equal to or less than a predetermined inter-vehicle distance set according to the vehicle speed, the CPU 20 stops outputting sound from the sound output means.

Next, the operation of the receiving apparatus 2 of the above embodiment will be described based on the flowcharts of FIGS.

First, if there is no hold data scheduled to be read aloud by voice, and there is received data of character information when voice reading is instructed by the operation switches 11 to 13 (steps S1 to S3), the I / O F30, 31
Then, the vehicle speed data of the own vehicle and the inter-vehicle distance data to the preceding vehicle are read via (steps S4, S5).

If there is any pending data in step S1, the process proceeds to step S4. If the predetermined switch operation is not detected in step S2, or if the reception of character data is not detected in step S3, The process moves to step S1.

From the input vehicle speed and inter-vehicle distance, it is not necessary to suspend the voice output in the current driving condition. That is, when it is determined that the voice output is possible, the reading of the suspended data and the reception data is performed. It is started (steps S6, S7). Further, when the suspension of the voice output is instructed from the vehicle speed and the inter-vehicle distance, that is, when it is determined that the voice output is not performed, the data to be read out is stored as the suspension data (steps S6 and S8).

Here, the determination as to whether or not to output a sound in step S6 is made based on the vehicle speed data and the inter-vehicle distance data input via the I / Fs 30 and 31, for example, as shown in FIG.
As shown in the figure, the distance between vehicles is 10m while driving at 10km / h.
In case 1, a voice output is performed. In case 2, the vehicle is traveling at 100 km / h and the inter-vehicle distance is 3 m.
At 3, control is performed to output audio.

As described above, the text-to-speech reading of the character information receiving device 2 is stopped in accordance with the running condition of the vehicle. Therefore, when the driver concentrates on the driving operation or when the driver needs to concentrate on the driving operation. Since the output of the text broadcast by voice can be stopped, the voice output can be reliably transmitted to the driver by preventing the voice output in a situation where it is difficult for the driver to recognize the text broadcast.

The sound output may be stopped when the vehicle speed is higher than a predetermined value.

[0023]

As described above, in the information receiving apparatus according to the present invention, the voice output is stopped in accordance with the running condition of the own vehicle. When it is necessary to output the character information by voice, the voice output can be reliably transmitted to the driver.
