The present invention and its embodiments will be described below based on the preferred examples shown in the drawings. The present invention is not limited to these examples.

[0020]

1 and 2, a notification device 1 of this example mounted on an automobile has a traveling speed detecting means 2 for detecting a traveling speed V of the automobile and various reference speeds, in this example. The generation means 3 capable of generating the speed limit VR for the traveling road, the comparison means 4 for comparing the travel speed V received from the travel speed detection means 2 with the speed limit VR received from the generation means 3, and the comparison means 4 are received. And a voice signal generating means 5 for generating a voice notifying that the traveling speed V exceeds the speed limit VR based on the comparison result.

The traveling speed detecting means 2 is provided with a so-called tachogenerator for detecting the rotational speed of the axle of the automobile, etc., and generates the detected rotational speed as an electric signal. The traveling speed detecting means 2 is not limited to one equipped with such a tachogenerator and the like, and may be another one using laser light or the like.

The generating means 3 capable of generating various speed limits VR as an electric signal is equipped with an operation panel having numerical keys arranged on an operation panel of an automobile, and by operating such numerical keys, The generated speed limit VR can be set externally by the driver of the vehicle. For example, the generating means 3 sets the speed limit VR to 60 k.
When m / H is set by operating the numeric keys, etc., the speed limit V
An electric signal indicating 60 km / H is generated as R, and when a speed limit VR of 80 km / H is set by operating a numeric key or the like, the speed limit VR is set to 8
The electric signal indicating 0 km / H is generated.

The comparison means 4 electrically compares the traveling speed V and the speed limit VR received during the traveling of the automobile, and indicates that the traveling speed has risen from below the speed limit VR to above the speed limit VR. The result and the running speed are the speed limit V
A comparison result indicating that the speed becomes equal to or higher than R and equal to or lower than the speed limit VR is generated as an electric signal.

The voice signal generating means 5 generates the voices to be generated based on the storage device 11 storing various voices as electric signals, the comparison result received from the comparing means 4 and the speed limit VR from the generating means 3. The determination / reader 12 that determines and reads from the storage device 11 and the speaker 13 that generates the sound read by the determination / reader 12 are provided.

The storage device 11 stores, for example, "a speed limit of 60 k.
"m / H exceeded", "speed limit exceeded 80 km / H" or "speed limit exceeded" and "speed limit exceeded 60 km / H", "speed limit 8"
Voices such as "exceeding 0 km / H" or "exceeding speed limit" are stored in advance as electric signals.

The determination / reader 12 determines that the traveling speed V is from the speed limit VR = 60 km / H or less to the speed limit VR = 60 km / H when the generating means 3 is generating the speed limit VR of 60 km / H. When the comparison result indicating the above is received from the comparison means 4, the storage device 1
From 1 to a voice notifying that the traveling speed V exceeds the speed limit VR, for example, "exceeding the speed limit 60 km / H"
Of the voice is read out from the storage device 11, and this voice is read by the speaker 1.
3 and send it from the speaker 13 to the "speed limit 60 km / H
Is exceeded. Also, for example, when the generation means 3 generates 80 km / H as the speed limit VR, the traveling speed V is the speed limit VR.
= 80 km / H or less and the speed limit VR = 80 km / H or more is received, when the comparison result is received from the comparison unit 4, the traveling speed V is the speed limit V from the storage device 11.
A voice notifying that R = 80 km / H has been exceeded, for example, a voice saying "The speed limit has exceeded 80 km / H" is read out from the storage device 11, and this voice is sent to the speaker 13 to output "speed limit 80 km" from the speaker 13. / H has been exceeded "is produced, and voices corresponding to other speed limits VR are similarly produced.

Further, the determining / reading device 12 determines that the traveling speed V is from the speed limit VR = 60 km / H or less to the speed limit VR = 60 km when the generating means 3 generates 60 km / H as the speed limit VR. / H is received and a voice notifying that the traveling speed V exceeds the speed limit VR = 60 km / H based on the comparison result, that is, "the speed limit 60 km / H is exceeded. Did"
When the same comparison result is received from the speaker 13 and before the predetermined time T1 elapses after the reception of the comparison result, the same comparison result is ignored. Further, for example, when the generating means 3 generates 60 km / H as the speed limit VR, it shows that the traveling speed V has changed from the speed limit VR = 60 km / H or less to the speed limit VR = 60 km / H or more. In the case where the speaker 13 issues a voice notifying that the traveling speed V exceeds the speed limit VR = 60 km / H based on the comparison result, and even after the comparison result is received. The traveling speed V is the speed limit VR = 60 km / H
When the comparison result indicating the above is continuously received, while the comparison result continues, the fact that the traveling speed V exceeds the speed limit VR = 60 km / H at every elapse of the predetermined time T2, That is, "the speed limit exceeds 60 km / H" or that the speed limit VR is exceeded, that is, "the speed limit is 60 k
The sound "M / H is exceeded" is read from the storage device 11, and the read sound is generated from the speaker 13. The speed limit VR is 80 km /
The same applies when the generating means 3 is generating H or the like.

Therefore, in the example of the traveling speed V of the vehicle shown in FIG. 2, the decision / reader 12 determines that the times t1 and t
From 3 to t8, sound is generated from the speaker 13, while at time t2, sound is not generated from the speaker 13.

It should be noted that the traveling speed V is integrated to obtain the traveling amount of the automobile, and instead of the predetermined times T1 and T2, the same operation as the predetermined times T1 and T2 is determined by traveling a predetermined amount.
It may be performed in the reader 12.

In the notification device 1 described above, the voice signal generating means 5 generates a voice notifying that the traveling speed V exceeds the speed limit VR of the traveling road.
Even if visual confirmation of the speed indicated by the speedometer of the automobile is neglected, it is possible to surely know that the speed limit VR has been exceeded, concentrate on visual confirmation outside the vehicle, and safely drive the automobile. Since various speed limits VR can be generated, for example, 40 km / H, 50 km /
H and 60 km / H and 80 km / H, etc. can be compared in accordance with the speed limits VR of various general roads and highways, so that it is possible to reliably know that the speed limit VR of the traveling road is exceeded. it can.

Further, in the notification device 1, the generation means 3 can be operated by the driver of the vehicle so that the generated speed limit VR can be set from the outside by the operation of the numeric keys or the like. It is possible to select a speed limit VR that is less than or equal to the optimum legal speed limit in relation to the degree of driving skill, and to know if the selected speed limit VR is exceeded, and to perform safer driving. When the vehicle speed increases or decreases the speed limit VR within the predetermined time T1, the traveling speed V becomes the speed limit VR.
It is possible to prevent the sound that announces that the
Therefore, it is possible to avoid the troublesome occurrence of meaningless repeated voices, and even when the voice notifying that the traveling speed V exceeds the speed limit VR is generated, it is still possible after a predetermined time has elapsed or a predetermined amount has traveled. If the traveling speed is continuously equal to or higher than the speed limit VR, the driver is instructed to generate a voice notifying that the traveling speed exceeds the speed limit VR or exceeds the speed limit VR. It is possible to repeatedly call out excesses and expect more safe driving.

In the notification device 1 described above, the speed limit VR can be set by the driver of the vehicle.
