KR960013819A - Vehicle Collision Hazard Alarm - Google Patents

Abstract

The present invention relates to a vehicle collision risk warning device. The apparatus of the present invention calculates the distance from a plurality of scan-type radars for measuring the distance to the surrounding vehicles, at least a plurality of CCD sensors for photographing the surrounding vehicles, an acoustic alarm for generating an alarm sound, and a measurement signal. And a control unit for driving the sound alarm by determining whether the calculated distance exists in the collision danger zone, a display unit for displaying the calculated distance or a photographing signal, and a display mode selection unit for selecting a display menu. Therefore, the present invention is not limited to the blind spot of the driver, but can look at the state difference existing anywhere in the vicinity of the own vehicle, and if the surrounding vehicle is present in the collision danger zone by generating an alarm sound to warn the driver in advance to prevent the collision in advance. It provides an effect that can be done.

Claims (8)

An apparatus for preventing a collision risk with relative vehicles in the vicinity of the vehicle, the apparatus comprising: distance measuring means mounted at an appropriate position of the vehicle and measuring a distance to the surrounding vehicle; A photographing means mounted at an appropriate position of the vehicle and configured to photograph surrounding vehicles; Calculate the distance to the surrounding vehicle from the measurement signal of the distance measuring means, determine whether the calculated there exists in the preset collision risk zone, drive the acoustic alarm according to the determination result, and supply the calculated distance to the display unit A control unit for performing; A display unit for displaying the calculated distance applied from the controller and a photographing signal applied from the photographing means; And an acoustic information device driven by the controller and configured to generate an alarm sound. The vehicle collision risk warning device according to claim 1, further comprising a display mode selection unit connected to the control unit for selecting whether to display the calculated distance from the surrounding vehicle with respect to the vehicle on the display unit. . According to claim 1 or 2, wherein the distance measuring means comprises a plurality of step motor driven by the control unit; And a plurality of scan-type radars for measuring the time when the beam is reflected while the step motor is driven and the beam is reflected. The vehicle collision risk warning device according to claim 3, wherein the scan radar is installed at the front, rear, left, and right positions of the vehicle. The vehicle collision risk warning device according to claim 1, wherein the photographing means is a plurality of CCD sensors. The vehicle collision risk warning device according to claim 5, wherein the CCD sensor is installed in conjunction with the scan radar. The apparatus of claim 2, wherein the controller converts the calculated distance into polar coordinates and supplies the converted distance to the display unit according to the display mode selection unit. The method of claim 7, wherein the control unit alerts by driving the acoustic alarm when the distance calculated by presetting a danger zone in which the vehicle may collide due to a lane change or a speed change is included in the danger zone. Vehicle collision hazard warning system. ※ Note: The disclosure is based on the initial application.
