Abstract

A driving support device for a vehicle uses a right speaker and a left speaker for providing audio information useful for driving to the right ear and left ear of a driver. Among the audio information useful for driving, speech guidance with the use of a voice is provided exclusively from the right speaker to the right ear of the driver.

Claims

1. A driving support device providing audio information useful for driving to a driver of a vehicle according to speech guidance by using voice,

wherein the driving support device provides the audio information useful for driving to a left ear and a right ear of the driver by using a right speaker and a left speaker;

and

wherein the speech guidance among the audio information useful for driving is provided to the right ear of the driver exclusively from the right speaker.

2. The driving support device according to claim 1,

wherein the right speaker is an ultrasound generation device for a right ear parametric speaker that generates a reproduced sound at the right ear by irradiating ultrasound toward a right ear position of the driver sitting on a driver seat of the vehicle;

and

wherein the left speaker is an ultrasound generation device for a left ear parametric speaker that generates the reproduced sound at the left ear by irradiating ultrasound toward a left ear position of the driver sitting on the driver seat.

3. The driving support device according to claim 1,

wherein the speech guidance is made in rhythm.

4. The driving support device according to claim 1,

wherein the audio information provided to the driver includes subliminal audio information.

5. The driver support device according to claim 1,

wherein the speech guidance with different content is individually in combination in accordance with a different warning sound.
