Technology Field

[0001] The present invention relates to a method and device for indicating an accident in a vehicle, and more specifically, to a method and device for indicating an accident in a vehicle that sprays a marking material onto a road surface to prevent secondary accidents caused by subsequent vehicles and to indicate the exact accident vehicle and accident location on the road surface when a car collision or the like occurs. Background Technology

[0002] Conventionally, when an accident occurs while driving on a road, the driver installs a triangle or similar device at a certain distance behind the accident site to prevent secondary accidents caused by subsequent vehicles, thereby allowing the driver to recognize that an accident has occurred.

[0003] However, in the event of an accident at night in environments where vehicles travel at high speeds, such as highways, a problem arises where the driver is exposed to danger while moving along the road to set up a warning triangle.

[0004] In addition, even if a driver installs a tripod, there is a problem in that it is difficult for a vehicle moving at high speed to identify a tripod installed on the road surface due to the limited size of the portable tripod.

[0005] In particular, there is a problem in that it is more difficult to perceive this in dark places such as at night or in tunnels.

[0112] In addition, the accident indicator device (100) of a vehicle according to one embodiment of the disclosed invention has the effect of preventing secondary accidents by utilizing a indicator material that is more visible than a conventional tripod in a dark place or at night where visibility is poor.

[0113] In addition, the accident indicator device (100) of a vehicle according to one embodiment of the disclosed invention has the advantage of being able to easily distinguish the location of the accident and the location where the accident vehicle (200) moved due to the collision using a indicating material, thereby facilitating the analysis of the accident scene.

[0114] In addition, the accident indicator device (100) of a vehicle according to one embodiment of the disclosed invention has the advantage that other vehicles (200) can easily recognize that an accident has occurred on the road by spraying a marking material onto the road surface at the time of the accident, even if the driver does not move the road to install a triangle.

[0115] In addition, the accident indicator device (100) of a vehicle according to one embodiment of the disclosed invention has the advantage of preventing the injection of a marking material in unnecessary situations where no accident, such as a simple sudden stop, occurs, by initiating the injection of a marking unit only when an impact greater than a set amount of impact is applied to the vehicle (200) and the speed of the vehicle (200) changes by a set rate of change of speed or more.

[0116] In addition, the accident indicator device (100) of a vehicle according to one embodiment of the disclosed invention has the advantage of being able to spray a indicator material with improved visibility depending on the environment by implementing different types of indicator materials sprayed during the day and at night.

Claims

Claim 1 An accident indicator device for a vehicle, comprising: a sensor unit configured to detect the amount of impact applied to the vehicle and the rate of change of speed of the vehicle; a marking unit mounted on the vehicle and configured to spray a marking material; and a processor that controls the marking unit based on information detected from the sensor unit; wherein the marking unit comprises a plurality of receiving portions for receiving different types of marking materials and a plurality of spraying portions each connected to the plurality of receiving portions, and wherein the plurality of receiving portions include a first receiving portion for receiving a first marking material sprayed onto the road when an accident occurs during daytime hours; and a second receiving portion for receiving a second marking material sprayed onto the road when an accident occurs during nighttime hours. Claim 2 delete Claim 3 delete Claim 4 An accident indicator device for a vehicle according to claim 1, characterized in that the plurality of injection parts comprises: a first injection part connected to the first receiving part and including a pump and a nozzle; and a second injection part connected to the second receiving part and including a pump and a nozzle. Claim 5 A vehicle accident indicator device according to claim 1, characterized in that the processor drives the marking unit when it is determined that the amount of impact applied to the vehicle detected by the sensor unit and the rate of change of speed of the vehicle per second are greater than or equal to a preset standard. Claim 6 A vehicle accident indicator device according to claim 5, wherein the sensor unit and the marking unit are composed of a plurality and are respectively positioned on the front, rear, left side, and right side of the vehicle, and the processor drives the marking unit positioned on the opposite side from the sensor unit to which the impact was applied. Claim 7 A method for indicating an accident in a vehicle, comprising: a step in which a sensor unit detects the amount of impact applied to the vehicle and the rate of change of speed of the vehicle; a step in which a marking unit sprays a marking material onto the road; and a step in which a processor controls the marking unit based on information detected from the sensor unit; wherein the marking unit comprises a plurality of receiving portions for receiving different types of marking materials and a plurality of spraying portions each connected to the plurality of receiving portions, and wherein the plurality of receiving portions include a first receiving portion for receiving a first marking material sprayed onto the road when an accident occurs during daytime hours; and a second receiving portion for receiving a second marking material sprayed onto the road when an accident occurs during nighttime hours.
