[0007]

In the above-described conventional car navigation system with a remote control, radio waves or infrared rays are transmitted arbitrarily by operating the operation panel of the car navigation or operating the buttons of the remote control to receive the car navigation. The department received this and performed the necessary operations. Therefore, when trying to perform a car navigation operation while driving a car, not only the movement of the line of sight but also the cumbersomeness of the operation and the like overlap, which often leads to an accident.

The present invention solves such disadvantages of the prior art and is easy to operate, especially when used for car navigation.
The purpose is to provide a remote control device that ensures safety.

[0009]

In order to achieve the above object, a first means is to process input signals from various switch groups by a main microcomputer, and to transmit an electric signal or an infrared signal from a transmission unit to be controlled. In a remote control device that irradiates a light toward a receiving unit of the device, the remote control device includes a microphone that converts a voice of an operator into an electric signal, and a voice recognition device that has a voice recognition LSI that identifies and processes a specific word from the electric signal. It is a feature.

The second means is the first means,
The microphone is a built-in microphone or a detachable external microphone.

The third means is the first means,
The device to be controlled is a car navigation device.

As described above, since the remote controller of the present invention has a voice recognition function,
It does not require manual operation and can be operated by voice. If this remote control with a voice recognition function is applied to a car navigation system, both hands can concentrate on driving operation even when operating the car navigation system while driving.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a conceptual diagram showing a use state of a car navigation system according to an embodiment of the present invention, FIG. 2 is an external configuration diagram of a remote controller according to an embodiment of the present invention, and FIG. FIG. 4 is an external configuration diagram of a remote controller according to a modification, and FIG. 5 is an external configuration diagram of a remote controller according to another modification.

As shown in FIG. 1, a car navigation system 3 mounted on an automobile 1 is electrically connected to an image display device 4 and an antenna 5 by connection cords 3a and 3b. The image display device 4 is installed in front of the driver 2. Remote control 7
Controls the main body function of the car navigation system 3, and is fixedly or movably installed at an arbitrary place according to the preference of the driver 2.

As shown in FIG. 2, a remote control 7 has a cursor control lever 7a, various switches,
A switch group 7b such as various mode switches is provided.
Of course, a radio wave or infrared irradiation unit is provided, and a part of the image display device 4 connected to the car navigation system 3 is irradiated with radio wave or infrared light to control the function of the car navigation system.

In the present invention, the remote controller 7 has a microphone 8, and the microphone 8
The sound generated by the driver 2 (for example, “up”, “up”, “down”
"Hidari""gasstation""chizukaiten", etc.
Specially predetermined words) are efficiently absorbed,
It is designed to convert to an electrical signal.

As shown in FIG. 3, a voice recognition LSI 9 is connected to the microphone 8, and the sound generated by the driver 2 is converted into an electric signal by the microphone 8, and the electric signal is converted into a specific word by the voice recognition LSI 9. Is recognized and processed. The output signal (recognized electric signal) from the voice recognition LSI 9 is processed by the main microcomputer 7c via the I / O port, and is transmitted to the transmission unit 7d.
As a result, the infrared signal 7e is radiated to a receiving unit (not shown) of the image display device 4.

If the remote controller 7 with the voice recognition function is used for the car navigation 3 as described above, the driver 2 can arbitrarily generate his / her desired place, destination, direction, and the like in the above-mentioned predetermined words. Only with this, the car navigation 3 can be easily operated. That is, the generated sound is the microphone 8
Recognition LSI having a conversion function as an input signal from the
The signal is processed by the CPU 9 and input to the main microcomputer 7c via the I / O port.

The main microcomputer 7c transmits an operation signal required for operating the car navigation system 3 to the transmitting unit 7d, and the infrared signal 7e from the transmitting unit 7d is arranged in a part of the image display device connected to the car navigation system 3. The car navigation 3 is remotely controlled.

The modification shown in FIG.
a is detachably mounted on the remote controller 7 in a jack-plug structure (in this case, of course, the built-in microphone 8 does not function electrically). The external microphone 8a can be arranged near the mouth where the sound generated by the driver 2 can be easily heard.

The output of the built-in microphone 8 or the external microphone 8a or the voice recognition LSI 9 can be cut off and used as a conventional remote controller.

The modified example shown in FIG. 5 eliminates the cursor control lever 7a (see FIG. 4) to provide a simple remote controller 7 having a microphone 8 and a switch group 7b, which is inexpensive and easy to operate and has an audio function. Things.

[0023]

According to the present invention, since the remote control has the voice recognition function, the target device can be operated by voice without the need for manual operation. If you apply this remote control with voice recognition to car navigation,
Even when operating the car navigation system while driving, both hands can concentrate on the driving operation only, which can contribute to ensuring safety. Further, if the microphone is an external microphone, it is possible to arrange the generated sound at the mouth which is easy to hear.
