Safety device for vehicles using multi-channel audio system
First Claim
1. A safety device for a vehicle, comprising:
- a multi-channel audio system including a plurality of speakers, a display unit and an audio circuit;
a plurality of sound wave sensors mounted on front and rear parts and left and right sides of the vehicle, each of which includes a sound wave generator for generating sound waves directed towards objects and a receiver for receiving sound waves reflected from the objects;
a plurality of A/D converters for converting analog signals of the reflected sound waves which are output from the sound wave sensors to digital signals; and
control means receiving the digital signals from the A/D converters to determine the presence of an obstacle and its location within a danger area around the vehicle, said control means providing output signals indicative of such obstacles and their location to the multi-channel audio system to generate warning sounds which differ depending on the location of the obstacle and to display information regarding the location of the obstacle on the display unit.

Abstract
The present invention relates to a safety device for a vehicle using a multi-channel audio system. The safety device of the present invention comprises a plurality of speakers, a display unit and an audio circuit. It further comprises a plurality of sound wave sensors mounted on front and rear parts and left and right sides of the vehicle, a plurality of A/D converters for converting analog signals of the reflected sound waves from the sound wave sensors to digital signals, and a control means for converting the information on the location of obstacles to speaker output signals if the obstacle is in the danger area such that sounds are generated by the speakers. Information on the location of the obstacle also may be displayed on the display unit.

2. A safety device for a vehicle, comprising:
-
a plurality of exterior proximity sensors disposed on the vehicle configured to sense obstacles;
a plurality of audio speakers disposed around the vehicle interior;
a controller communicating with said sensors and speakers, said controller receiving signals from said sensors indicative of at least obstacle locations and generating signals output to said speakers to cause said speakers to emit sounds representative of a sensed obstacle and its location. - View Dependent Claims (3, 4, 5, 6, 7)
