DRIVING ASSIST DEVICE FOR VEHICLE
First Claim
1. A driving assist device for a vehicle which is equipped with plural speakers for a driver, comprising:
- an object detecting means to detect an object existing around the vehicle;
a danger-degree detecting means to detect a degree of danger of collision or contact of the object detected by said object detecting means with the vehicle;
a direction detecting means to detect a direction of the object which has a critical state in the degree of danger of collision or contact with the vehicle which is detected by said danger-degree detecting means;
a distance detecting means to detect a distance of the object existing around the vehicle from the vehicle;
an alarm-sound creating means to create an alarm sound according to the distance of the object which is detected by said distance detecting means and the direction of the object which is detected by said direction detecting means;
a reference sound creating means to create a reference sound which enables the driver to recognize the distance of the detected object from the vehicle when the driver hears the alarm sound created by said alarm-sound creating means, comparing with the reference sound; and
a sound generating means to generate the alarm sound created by said alarm-sound creating means and the reference sound created by said reference sound creating means at the same time or a different timing via the speakers for the driver.

Abstract
An alarm sound according to the distance of a dangerous object exiting around a vehicle is created. A reference sound which enables a driver to recognize the distance of the dangerous object when the driver hears the alarm sound, comparing with the reference sound, is created. The alarm sound and the reference sound are generated at the same time or a different timing. It is preferable that the sound volume of the alarm sound be greater than that of the reference sound. Accordingly, the driver can be warned precisely of the distance of the dangerous object from the vehicle with the sound.
