Problems solved by technology

[0013] However, since the devices or devices described in Patent Documents 1 to 3 cannot accept a predetermined input operation when the driving environment is in a certain state, when the predetermined state used as the judgment standard cannot be properly set, excessive restrictions will be caused. Input operation, I have to say lack of simplicity of use
[0014] In addition, the display control device for a vehicle described in Patent Document 4 does not completely prohibit the driver's input operation even when the driving environment is in a predetermined state, but does not clearly indicate how to omit which function in which vehicle-mounted device is executed. Which menu item is selected, so that it cannot judge its operability

Embodiment Construction

[0050] The best mode for implementing the present invention will be described below with reference to the drawings.

[0051] figure 1 It is a block diagram showing a configuration example of the in-vehicle information retrieval device of the present invention. The in-vehicle information retrieval device 100 retrieves information (e.g., the location of the destination) corresponding to those inputs (e.g., destination name) based on the operator’s hand input or voice input ) And output (for example, display a surrounding map or route), which is composed of a control unit 1, a hand input unit 2, a voice input unit 3, a driving environment state detection unit 4, a storage unit 5, a display unit 6, and a voice output unit 7. .

[0052] The control unit 1 is a computer equipped with a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), a speech recognition processor, etc., for example, the ROM stores corresponding fuzzy tolerance determination units 10, T...

Abstract

An on-vehicle information detection device (100) searches for information according to a word inputted by an operator manual operation or via a voice input. The device (100) includes: travel environment state detection means (4) for detecting a travel environment state; ambiguity allowance decision means (10) for deciding the allowance for ambiguity of the inputted word according to the travel environment state detected by the travel environment detection means (4); and information search means (11) for searching for information in accordance with the allowance decided by the ambiguity allowance decision means (10).

Description

Technical field [0001] The present invention relates to an in-vehicle information retrieval device that retrieves and displays information corresponding to an operator's hand input or voice input, and more particularly relates to an in-vehicle information retrieval device that changes tolerance to the ambiguity of those inputs according to the state of the driving environment. Background technique [0002] In the past, in-vehicle electronic devices that restrict allowable input operations and display information according to the driving environment, or change the reading speed of voice guidance have been known (for example, refer to Patent Document 1). [0003] This in-vehicle electronic device, for example, is unable to accept the hand input that has been accepted until the vehicle speed increases, or no longer displays the information that has been displayed before, or reduces the reading of the voice guidance output instead of the information that has been displayed before. The ...
