KR-20260067027-A - System for preventing vehicle collisions when a front object is moving backwards

Abstract

The present invention relates to a vehicle collision prevention system when a front object is reversing, which may include a distance measuring sensor for measuring the distance to a front object; a vehicle speed sensor for measuring the driving speed of the vehicle; a front light for emitting light toward the front of the vehicle; a horn for generating a horn sound; and a vehicle control unit that, when the vehicle driving speed is decelerated to a level below a preset threshold, calculates the probability of collision with a front object based on the distance to the front object, and if there is a probability of collision, performs a warning operation using at least one of the front light and the horn.

Claims (3)

1. A distance measuring sensor that measures the distance to a forward object; A vehicle speed sensor that measures the driving speed of the vehicle; Front light emitting light toward the front of the vehicle; A horn that produces a horn sound; and A vehicle collision prevention system for a vehicle when a vehicle moves backward, comprising a vehicle control unit that calculates the possibility of collision with a forward object based on the distance to the forward object when the vehicle driving speed is decelerated to below a preset threshold, and performs a warning operation using at least one of the forward light and the horn if there is a possibility of collision.
2. In paragraph 1, the vehicle control unit A vehicle collision prevention system for a vehicle when a front object is reversing, characterized by driving the front light when the distance to the front object is less than or equal to a preset first distance, and additionally driving the horn in addition to the front light when the distance to the front object decreases to a second distance shorter than the first distance.
3. In paragraph 1, the vehicle control unit A vehicle collision prevention system for a front object reversing, characterized by accumulating the warning execution time until the distance to the front object increases beyond a preset first distance when a warning operation is initiated, and increasing the warning intensity as the warning execution time elapses.

Description

System for preventing vehicle collisions when a front object is moving backwards The present invention relates to a vehicle collision prevention system for a front object reversing to reduce the likelihood of a traffic accident caused by rearward inattention of the front object. Generally, a collision avoidance device refers to a safety device designed to prevent or avoid a vehicle collision. Recently, various safety technologies are being developed to prevent automobile accidents. However, these technologies are designed to minimize casualties in the event of an accident and cannot prevent accidents beforehand. Accordingly, a Forward Collision-Avoidance Assist (FCA) system was proposed, which recognizes the distance to a preceding vehicle or pedestrian through distance sensing sensors and alerts the driver to the risk of collision. However, this forward collision avoidance assist system warns the driver of the risk of collision, but it does not warn vehicles or people in front of the collision risk situation. Consequently, there is a limitation in that if a vehicle or person in front reverses toward the vehicle when the driver can no longer reverse due to accident prevention, a traffic accident is inevitably bound to occur. Referring to FIG. 1, the present invention relates to a vehicle collision prevention system when a front object reverses according to one embodiment of the invention. FIGS. 2 and FIGS. 3 are drawings for explaining a vehicle front collision prevention method according to an embodiment of the present invention. FIG. 4 is a drawing illustrating a vehicle front collision prevention method according to another embodiment of the present invention. Before specifically describing the present disclosure, the method of description in the specification and drawings is described. First, the terms used in this specification and claims have been selected based on general terms considering their functions in the various embodiments of this disclosure. However, these terms may vary depending on the intent of those skilled in the art, legal or technical interpretations, and the emergence of new technologies. Additionally, some terms have been arbitrarily selected by the applicant. Such terms may be interpreted according to the meanings defined in this specification; in the absence of specific definitions, they may be interpreted based on the overall content of this specification and common technical knowledge in the relevant field. In addition, the same reference numbers or symbols described in each drawing attached to this specification represent parts or components that perform substantially the same function. For convenience of explanation and understanding, the same reference numbers or symbols are used to describe different embodiments. That is, even if components having the same reference number are all depicted in multiple drawings, the multiple drawings do not imply a single embodiment. Additionally, in this specification and claims, terms including ordinal numbers, such as "first," "second," etc., may be used to distinguish between components. These ordinal numbers are used to distinguish identical or similar components from one another, and the meaning of the terms should not be limited by the use of such ordinal numbers. For example, the order of use or arrangement of components combined with such ordinal numbers should not be restricted by the number. If necessary, each ordinal number may be used interchangeably. In this specification, singular expressions include plural expressions unless the context clearly indicates otherwise. In this application, terms such as "comprising" or "consisting of" are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. In the embodiments of the present disclosure, terms such as "module," "unit," "part," etc. are used to refer to a component that performs at least one function or operation, and such component may be implemented in hardware or software, or a combination of hardware and software. Additionally, a plurality of "modules," "units," "parts," etc. may be integrated into at least one part or chip and implemented as at least one processor, except where each needs to be implemented in specific individual hardware. Furthermore, in the embodiments of the present disclosure, when a part is described as being connected to another part, this includes not only a direct connection but also an indirect connection through another medium. Additionally, the meaning that a part includes a certain component implies that, unless specifically stated otherwise, it does not exclude other components but may include additional components.
