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 accompanying drawings.

[0051] figure 1 It is a block diagram showing a configuration example of the vehicle-mounted information retrieval device of the present invention. The vehicle-mounted information retrieval device 100 retrieves information (such as the position of the destination) corresponding to those inputs (such as the name of the destination) based on the operator's hand input or voice input. ) and output (such as displaying a surrounding map or a route) 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), a RAM (Random Access Memory), a ROM (Read Only Memory), a speech recognition processor, etc., and stores, for example, ROMs corresponding...

Abstract

An onboard information retrieval apparatus 100 for retrieving information based on a word inputted via manual or voice input by an operator includes a travel environment condition detecting unit 4 for detecting a travel environment condition; an ambiguity tolerance determination unit 10 for determining a tolerance level for ambiguity in the inputted word based on the travel environment condition detected by the travel environment detecting unit 4; and an information retrieval unit 11 for retrieving the information in accordance with the tolerance level determined by the ambiguity tolerance determination unit 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 ambiguity of those inputs according to the driving environment state. Background technique [0002] Conventionally, in-vehicle electronic devices are known that limit allowable input operations and display information, or change the reading speed of voice guidance according to the driving environment (for example, refer to Patent Document 1). [0003] This vehicle-mounted electronic device, for example, cannot accept the hand input that has been accepted until now with the increase of the driving speed of the vehicle, or no longer displays the information that has been displayed until now, or reduces the reading of the voice guidance that has been output instead of the information t...
