Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a rear-end collision prevention warning brake light that informs following vehicles of the distance and speed between the own vehicle and the vehicle in front while the vehicle is running.

(Prior Art) Due to the proliferation of cars in recent years, there is little hope of reducing car accidents, and the rate of rear-end car accidents is extremely high. Generally, in the case of a rear-end collision,
When driving at high speed and not keeping a proper distance from the vehicle in front, the vehicle in front suddenly stops and the vehicle behind cannot stop, resulting in a rear-end collision. If I was only careful enough, I would end up shortening the following distance or driving too fast, so I tried using millimeter-wave radar, sonic radar, and other methods to measure the distance between the vehicle and the vehicle in front. A system has been devised that uses optical sensors to notify the driver.

(Problem that the invention aims to solve) However, all of these methods use radar to check the distance between your vehicle and the vehicle in front of you, so although it is possible to alert you to the vehicle in front of you, The most terrifying type of rear-end collision is a head-to-head collision, in which the driver only pays attention to the vehicle in front of him, and is unable to determine the distance between the vehicle in front of him and the vehicle in front of him. A major problem remained, as the sudden stop of a vehicle often resulted in a rear-end collision with the vehicle in front of it, which in turn led to a rear-end collision with the own vehicle.

The present invention has been developed in view of the above points, and by notifying the vehicle behind the vehicle of the distance and speed relationship between the vehicle in front and the vehicle in front, it is possible to set an appropriate distance between the vehicle and the vehicle behind the vehicle. To provide a warning brake light for preventing a rear-end collision of a motor vehicle, which warns drivers to stop and brake the vehicle freely.

(Means for Solving the Problems) The gist of the present invention to achieve the above object is that a sensor 1 is provided at the front of the vehicle 3 to sense and measure the distance between the vehicle and the vehicle ahead. A warning brake light for preventing a rear-end collision of a motor vehicle is characterized in that it is connected to a speedometer and also linked to a warning brake light 2 provided at the rear of a vehicle 3.

(Function) As described above, if each vehicle 3 is equipped with the rear-end collision prevention warning brake light of the present invention, the sensor 1 measures the inter-vehicle distance to the vehicle in front, and the warning brake light 2 at the rear of the vehicle 3 is sent to the rear vehicle. It can be confirmed by
In the unlikely event that your vehicle suddenly stops due to the sudden stop of the vehicle in front, the vehicle behind you will always be aware of the driving conditions of the two vehicles in front of you, so there is no need to worry about rear-end collisions. There is no need to worry about this.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a perspective view showing the front side of the vehicle, FIG. 2 is a perspective view showing the rear side of the vehicle, and FIG. 3 is a side view showing the state of use.

In the drawing, 1 is a sensor that is installed in front of a car 3 and measures the distance between the car and the car in front.It transmits radio waves, ultrasonic waves, light, etc. from the front of the car 3 and reflects them back to the car in front. Depth finders (sonars) are commonly used water depth finders (sonars) that measure the round trip distance by receiving and sensing the arrival time, etc.
The principle is the same as that of altimeters and altimeters. The sensor 1 is connected to a speedometer to measure the speed of the vehicle ahead, but on the contrary, it can be set so that the sensor 1 does not operate below the speed of the vehicle. 2 is a warning brake light that is linked to sensor 1 and displays information obtained by sensor 1 (vehicle distance,
This is to automatically notify the vehicle behind you of the vehicle speed.For example, several types of colored lamps are arranged, and the difference in the following distance and speed is distinguished by color, or the lights are turned on. Measures can be taken such as setting each stage according to the number of flashing lamps, but there is no particular limitation, and the point is that when three cars are running in succession, the driving state of the two cars in front As long as the display method is such that the rear-end vehicle can understand the information, it is acceptable to use a digital display rather than a lamp display. In addition, in case of traffic jams or when parking in a garage, please check the vehicle in front (or an obstacle).
Although the distance between the vehicle and the brake light is very narrow, the risk of a rear-end collision is low, so the sensor 1 and warning brake light 2 may not operate at low speeds (for example, the activation start speed may be changed to 30Km
, and if the safe following distance is set to 30m, sensor 1 will be activated when car 3 reaches a speed of 30km/h or more, and warning brake light 2 will turn on when the distance from the vehicle in front becomes less than 30m. The light shall be turned on to notify the vehicles behind. ), and since the traveling speed and safe inter-vehicle distance differ between ordinary roads and expressways, setting values may be set for each and switched as appropriate to operate in accordance with each type of road. Of course, in addition to the display for the vehicle behind, there is also a display section in front of the driver's seat that displays the distance from the vehicle in front.
It is also possible to incorporate a device or control device that issues an alarm when the following occurs.

(Effects of the invention) As explained above, according to the invention, it is possible to not only know the distance between the vehicle in front of the vehicle, but also to know the driving status of the vehicle in front and the vehicle in front by using the warning lights at the rear of the vehicle in front. (The driving condition between the vehicle in front and the own vehicle can be confirmed by the warning brake light at the rear of the vehicle.) Therefore, the driver of each vehicle traveling in succession can check the driving condition of the vehicle in front of the vehicle in front. This allows the user to drive while checking the vehicle's condition, allows the user to drive with ample time without having to leave an unnecessarily large gap between the vehicle and the vehicle in front, and is effective in preventing rear-end collisions.
