Abstract

PROBLEM TO BE SOLVED: To provide an in-vehicle guidance device by which an atmosphere in a cabin is kept, and no important guidance is missed by changing a content and voice quality of a guidance to be output according to a situation in the cabin.SOLUTION: Output conditions of a voice guidance are changed according to set sound volume of output sound of an in-vehicle device.

Description

  The present invention relates to an on-vehicle guidance device.

  In conventional in-vehicle guidance devices, the output volume of the guidance output from the speaker is always constant, despite the fact that the conditions inside the vehicle have changed in various ways, and in-vehicle such as TV (Television), radio, audio, etc. When watching sports or listening to rock on a device, there was a problem of missing important guidance. For this reason, a microphone for collecting the output sound of the in-vehicle device is provided at a place where the sound of the in-vehicle device is output, and the output volume of the guidance is automatically changed according to the volume of the output sound collected by the microphone. (For example, refer to Patent Document 1).

Japanese Patent Laid-Open No. 11-55055

  Conventional in-vehicle guidance devices only change the volume of the guidance, and since the guidance is always output with fixed contents and voice color, watching sports on in-vehicle devices such as TV, radio, audio, etc., and locking When the atmosphere in the vehicle is exciting, such as when listening, the guidance is unexpectedly output with a quiet and calm voice, and there is a problem that water is poured into the corner atmosphere. In addition, the guidance output volume is changed according to the volume of the output sound of the in-vehicle device, and other environmental sounds in the car are not taken into account. There was a problem that it was sometimes missed.

  The present invention has been made to solve the above-described problems, and by changing the content and voice color of the guidance to be output according to the conditions in the vehicle, it is important not to give water to the atmosphere in the vehicle. An object of the present invention is to obtain an in-vehicle guidance device that does not miss the guidance.

  The in-vehicle guidance device according to the present invention is characterized in that the output condition of the voice guidance is changed according to the set volume of the output sound of the in-vehicle device.

  According to the present invention, since the guidance output condition is changed according to the situation inside the vehicle, there is an effect that the guidance can be efficiently transmitted to the passenger without putting water into the atmosphere inside the vehicle.
