Description

Deformable vehicle auxiliary braking light and auxiliary braking system including the same

The present invention relates to a deformable auxiliary braking light for a vehicle and an auxiliary braking system including the same.

In general, a braking light is provided at the rear of the vehicle to notify the following vehicle of the braking situation of the vehicle. In addition, a separate auxiliary brake light may be further provided to increase discrimination and cognitive ability.

These auxiliary brake lights are driven in the same way as the brake lights. Specifically, when the driver presses the brake for deceleration of the vehicle, it is configured to be turned on by sensing the pressure of the brake. However, since the conventional auxiliary braking lamp as described above is turned on only when the brake is operated, there is a problem that it is difficult for the following vehicle to recognize that the vehicle is decelerated when the vehicle is decelerated without the brake operation.

In general, a vehicle driver recognizes the deceleration of the preceding vehicle, but mainly visually relies on the brake lights of the preceding vehicle, so if the brake lights do not light even when the preceding vehicle slows down, they cannot quickly recognize the deceleration of the preceding vehicle and collide. It can lead to an accident. In addition, since the lighting of the auxiliary braking lamp is constant regardless of the difference between the degree of deceleration and the case of sudden, it is difficult for the driver of the vehicle to recognize the degree of deceleration of the preceding vehicle. There is a difficult problem.

In particular, on the highway, the vehicle travels at a speed of 100 km/h or more, so momentary alertness leads to an accident, and once an accident occurs, it often leads to a major accident. In emergency situations (breakdowns, traffic accidents, etc.) that require parking and stopping, necessary measures, such as moving the car to a place other than highways, must be taken in accordance with Article 66 of the Road Traffic Act, and a red flashing signal that can be identified at 500m in all directions. Necessary measures, such as installing electric lanterns or spark signals, and/or safety tripods, should be taken.

However, according to the regulations on the installation of the safety tripod, the driver must get off to install the safety tripod, and during the time between getting off and the installation of the safety tripod, the driver may collide with a subsequent vehicle, that is, a secondary accident. You are exposed to risks as they are, and these risks can be significantly aggravated depending on the time of day and climatic conditions.

The present invention is to solve the problems of the prior art, and an object of the present invention is to allow the driver of the preceding vehicle to visually recognize that the preceding vehicle is in an emergency parking stop state to the driver of the following vehicle during emergency parking and stopping of the preceding vehicle.

5 is a schematic diagram of an auxiliary braking lamp according to another embodiment of the present invention. Referring to FIG. 5, the auxiliary brake light includes a housing and a luminous body mounted inside the housing, and in the emergency parking and stopping state of the vehicle, the housing may be transformed into a two-dimensional shape by a chemical means or a combination of a chemical means and an electrical means. I can. The chemical means may be illustrated as a case where the housing includes a shape memory material, but is not limited thereto.

The shape memory material has a property of recovering to its original shape when an external stimulus of the same shape, which is deformed and fixed by an external stimulus, is secondarily applied. As the shape memory material, a shape memory alloy such as nitinol or a polyurethane shape memory polymer is widely known. While the shape memory alloy is expensive, it has problems such as low strain recovery and low transition temperature. On the other hand, shape memory polymers are light, easy to process, and excellent in deformation recovery.

The housing may include a shape-memory material synthesized to have a specific shape in a specific external stimulus, and the external stimulus may be a physical condition such as temperature, pressure, and vibration. It can be provided by an electrical signal that occurs when placed. In this case, the electric signal may be generated manually by the driver, automatically generated by an electronic device such as a sensor or a radar, or may be generated semi-automatically by the driver and the electronic device.

The emergency parking and stopping state and/or the flashing and lighting patterns of the light emitter according to the electrical signal may be provided through various methods and paths. As used herein, the term “lit” refers to a state in which light is continuously emitted from a light source for a certain period of time or longer, and “blinking” refers to a state in which light intermittently blinks from a light source at a certain period.

As described above, the electrical signal may be generated manually by the driver, automatically generated by an electronic device such as a sensor or a radar, or may be generated semi-automatically by the driver and the electronic device.

6 is a schematic diagram of an auxiliary braking system according to another embodiment of the present invention. Referring to FIG. 6, the auxiliary braking system includes an input unit 300 for acquiring information by recognizing an emergency parking and stopping state of the vehicle; A control unit 400 for providing an electric signal to an auxiliary braking lamp for a vehicle according to the information received from the input unit; And the auxiliary brake light for the vehicle driven by the electric signal.

The electrical signal may be provided by a control unit 400 provided separately from the auxiliary brake light for the vehicle, and the control unit 400 passively and/or automatically recognizes that the vehicle is in emergency parking or a similar state to obtain information, It may be provided at an arbitrary position between the transmitting input unit and the vehicle auxiliary braking lamp.

Flashing and/or lighting driving of the vehicle auxiliary braking lamp according to each case may be illustrated as follows, but is not limited thereto.

(1) The input unit 300 may be passively driven by a driver. In general, when the driver recognizes that the driver is in an emergency parking or stop state such as an accident or a breakdown, pressing the emergency flashing indicator button provided on the dashboard, center facia, etc. causes all the turn indicators to blink in daylight (yellow) at the same time. The conventional auxiliary brake light turns on in red (red) when the brake pedal is pressed and the brake is operated regardless of whether the vehicle is running or parked, and turns off when the brake pedal is not pressed.

In contrast, according to an embodiment of the present invention, the input unit 300 may be configured to have a structure in which the emergency flashing indicator button is pressed in two steps according to a pressing strength.

Through this structure, it is possible to cause the emergency flashing indicator to flash as in the prior art when the first step is pressurized, and when the pressure is stronger than the pressure in the first step, that is, when the second step is pressurized, the control unit ( 400), and the control unit 400 may generate an electrical signal for transforming and flashing (or lighting) the auxiliary brake light into a two-dimensional shape based on the received information.

That is, when the second stage of pressure is applied, the auxiliary brake lamp is transformed into a two-dimensional shape, and the emergency flashing lamp may maintain a flashing state. The input unit 300 may be provided as an emergency flashing indicator button of a two-stage pressurization method as well as other unrestricted operation means. In this case, the emergency flashing indicator is displayed in a state in which the auxiliary brake light is transformed into a two-dimensional shape. It can be kept blinking or turned off as needed.

In addition, the portion between the hinges of the auxiliary brake lights of Fig. 1, the first sub-structure of Figs. 2 to 4, and the auxiliary braking lights of Fig. 5 are driven in the same manner as the conventional auxiliary braking lights when the auxiliary braking lights are not in an emergency parking and stop state. It can be driven by configuring a part of a two-dimensional shape.

(2) The input unit 300 may be automatically driven by an arbitrary sensor provided in the vehicle, for example, an infrared-based speed sensor. In general, a vehicle is provided with a sensor capable of detecting specific behaviors such as sudden braking and sudden start of the vehicle, and such a sensor may act as an input unit 300 to the control unit 400. For example, when the speed sensor detects acceleration indicating that the vehicle is in a sudden braking state, the speed sensor may transmit information indicating an emergency parking and stop state to the control unit 400, and the control unit 400 is Based on the information, an electric signal for transforming and flashing (or lighting) the auxiliary brake light into a two-dimensional shape may be generated.

However, since sudden braking of a vehicle occurs very frequently compared to accidents and breakdowns, if the auxiliary brake light is transformed into a two-dimensional shape and flashes (or lights up) whenever sudden braking is performed in a general driving environment, unnecessary misunderstandings and confusion are caused by nearby drivers. Can evoke. Accordingly, in the case of a system in which the input unit 300 is automatically driven by a sensor, it may be provided so that a driver can activate/deactivate through a separate on/off switch in a driving environment where sudden braking hardly occurs.

In addition, the portion between the hinges of the auxiliary brake lamp of FIG. 1 and the first sub-structure of FIG. 2 are not in an emergency parking and stop state, specifically, the input unit is not pressurized, pressurized only up to step 1, or additional pressurized after pressurizing step 2 When the emergency parking and stopping state is released, it is driven in the same manner as a conventional auxiliary brake lamp, and in the emergency parking and stopped state, it can be driven by forming a part of a two-dimensional shape.

The above description of the present invention is for illustrative purposes only, and those of ordinary skill in the art to which the present invention pertains will be able to understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present invention. will be. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not limiting. For example, each component described as a single type may be implemented in a distributed manner, and similarly, components described as being distributed may also be implemented in a combined form.

The scope of the present invention is indicated by the claims to be described later, and all changes or modified forms derived from the meaning and scope of the claims and the concept of equivalents thereof should be construed as being included in the scope of the present invention.
