Abstract

PURPOSE:To reduce opportunity to detach hands from a handle in operation during driving and to improve safety by providing an automatic input switching part to judge the classification of an inputted signal, to automatically switch the signal and to supply the signal to an operation input control part. CONSTITUTION:A driver arbitrarily input operation instruction information with a key or a sound. For example, when the input is executed with the key, the key input is executed from a key input part 24 and a key input signal is supplied to an automatic input switching part 11. Then, the automatic input switching part 11 judges the classification of the inputted signal and supplies the inputted key input signal to an operation input control part 12. After that, the key input signal is converted to a key code with the operation input control part 12 and stored to a memory part 33. For example, when the input is executed with the sound, the sound input is executed from a sound input part 25 and sound recognition processing is executed with a sound recognition part 26. Then, the sound data of a matched result are supplied to the automatic input switching part 11 and the automatic input switching part 11 judges the classification of the inputted signal. After that, the inputted sound data are supplied to the operation input control part 12. Thus, manual operation for switching is eliminated and the safety can be secured.

Next, the operation of the conventional in-vehicle navigation device will be explained.

First, the driver switches the changeover switch of the operation input control section 29 depending on whether the driver inputs operation instruction information by key input or by voice. For example, in the case of key input, the key input is performed from the key input section 24, and the key code converted by the key input control section 28 is stored in the memory section 33 via the operation input control section 29. Further, in the case of voice input, for example, voice input is performed from the voice input section 25, and the voice data that is the result of voice recognition performed by the voice recognition section 26 and matched is converted into a key code by the voice input control section 27. Further, the key code is stored in the memory section 33 via the operation input control section 29. Then, the information processing section 30 reads desired map data from the map file section 23 according to the key code, which is operation instruction information stored in the memory section 33, and stores it in the memory section 33. The map data is then supplied to the display section 22 via the display control section 31, and the map desired by the driver is displayed on the display section 22.

(Problem to be Solved by the Invention) However, in the conventional device described above, switching between key input and voice input was performed manually, so manual operation while driving a car poses a safety problem. there were.

The present invention is intended to solve this problem, and aims to provide an in-vehicle navigation device that ensures safety.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a key input unit for instructing operation by key input in an in-vehicle navigation device that displays information necessary for driving a car etc. on a display. a voice input section that gives operation instructions through voice input; a voice recognition section that recognizes input voice; an operation input control section that converts input signals from key input or voice input; an automatic input switching unit that determines the type and automatically switches and supplies the input signal to the operation input control unit; a storage unit that stores various information;
The present invention is characterized in that it includes an information processing section that reads desired information from the storage section according to the code converted by the operation input control section and supplies it to the display as display data.

(Function) According to the present invention having the above-described configuration, first, the driver arbitrarily uses either the key input unit for giving operation instructions by key input or the voice input unit for giving operation instructions by voice input. Carry out the operation for 1 hour. Then, the automatic input switching section determines the type of the input signal, and automatically switches and supplies the input signal to the operation input control section. The operation input control section converts input signals from key input or voice input into codes. The information processing section reads out desired information from the storage section in which various information such as map display data is stored, and supplies it to the display as display data, according to the operation input control section number and the code obtained by conversion.

Desired information is displayed on the display.

Therefore, the present invention can solve the above problems and provide an in-vehicle navigation device that ensures safety.

(Example) Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows the configuration of an embodiment of the present invention.
It is a diagram of r>i. In this figure, the same reference numerals as in FIG. 2 indicate the same components. The different components are 1
Reference numeral 1 is composed of a multiplexer, etc., and determines the type of each signal, automatically switches the signals from the key input section 24 or the voice input section 25, and the voice recognition section 26, and supplies the signals to the operation input control section 12, which will be described later. Input automatic switching section, 1
Reference numeral 2 denotes an operation input control section that converts a signal input through the automatic input switching section 11 into a key code.

Next, the operation of the in-vehicle navigation device of this embodiment will be explained.

First, the driver inputs operation instruction information either by key input or by voice. For example, in the case of key input, the key input is performed from the key input section 24, and a key input signal is supplied to the automatic input switching section 11. The automatic input switching section 11 determines the type of the input signal and supplies the input key input signal to the operation input control section 12 . The operation input control unit 12 converts the key input signal into a key code and stores it in the memory unit 33. Further, in the case of voice input, for example, voice input is performed from the voice input section 25 , and the voice data is subjected to voice recognition processing by the voice recognition section 26 and matched, and the resulting voice data is supplied to the automatic input switching section 11 . The automatic input switching section 11 determines the type of the input signal and supplies the input audio data to the operation input control section 12 . Operation input control section 1
2 converts the audio data into a key code and stores it in the memory section 33; Then, the information processing section 30 reads desired map data from the map file section 23 according to the key code, which is operation instruction information stored in the memory section 33, and stores it in the memory section 33. The map data is then supplied to the display section 22 via the display control section 31, and the map desired by the driver is displayed on the display section 22.
