  • Publication number: 20150244994
    Abstract: The present invention relates to a shock sensing device for vehicle and method for controlling thereof. The present invention comprises, at least one shock sensing sensor installed in a vehicle, at least one camera wherein rotates to a predetermined direction when shock sensing signal is generated from the shock sensing sensor and installed to film at least one direction of front or back of a vehicle, an image processing unit wherein recognizes front and back direction of a crashed vehicle and crash point where crash occurred based on image information collected from the rotating camera and, a control unit wherein senses filming direction of the camera and stops the camera when the camera's filming direction is directed and controls to store image information regarding crash vehicle.
