[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle rear-end collision prevention device.

[0002]

2. Description of the Related Art A conventional vehicle only warns a following vehicle in order to prevent a rear-end collision by a display warning during braking that lights up a brake light when the brake is depressed. For this reason, a vehicle running at a speed lower than the set speed (low-speed driving state) and at the time of deceleration driving during medium-speed or high-speed driving does not have a means for giving a preliminary warning to the following vehicle. On the other hand, the permissible practical traveling speed of a car is increased by improving the performance of the car itself and maintaining road roads, driving signs, etc.Especially, repeated collisions on the highway suggest the necessity of the above warning warning. ing.
However, the actual implementation of this kind of warning device is delayed, and there are many end-to-end accidents.

[0003]

SUMMARY OF THE INVENTION The present invention was devised for the purpose of solving the above-mentioned problems of the prior art and eliminating any rear-end collision accidents. When the vehicle is in a low speed operation state below a set speed, , and medium speed exceeds the low speed operation, when in the decelerating operation state even during high-speed operation, the brake lights or tail lights some
I use the brake lights and tail lights as warning lights ( hereinafter called warning lights )
It flashes or lights continuously to inform the following vehicle that it is in a rush, low-speed driving state, or a deceleration driving state during medium-speed or high-speed driving, or both, and alerts the following vehicle to warn of a rear-end collision. It is an object of the present invention to provide a device that can prevent such a situation from occurring.

This invention SUMMARY OF THE INVENTION In order to achieve the problems described above, as shown in FIG. 1, driving a car switch
Turn on when the engine is started with the switch on, switch off
Te When the engine is stopped and the contact 1 to be OFF, the car fast
If the degree is below the set speed, it will be ON, and if it exceeds the set speed, it will be OFF.
The made contact 2 connected, either via the flasher 4, not through
Together it can be connected flashing lighting circuit warning lamp 5, Accession
It will be ON when you release your foot from the cell, and OFF when you step on the accelerator.
Contact 3 and ON during normal operation, and during automatic constant speed running operation
The contact 6 that turns off and turns on when the automatic constant-speed running operation is canceled
Connect them in series by connecting them in parallel to the contact 2 and step on the brake.
The contact 7 that turns on when it is turned off and turns off when you release your foot is the contact 2
The contact 3 connected in parallel to the contact 2 Contact and the contact 6
Rear-end collision prevention for automobiles connected in parallel to the series connection circuit
The device is the means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. In the figure, 1 is a contact point that is turned on when the driving switch of the vehicle is turned on and the engine is started, and is turned off when the engine is stopped and the engine is stopped, and 2 is when the speed of the vehicle is below a set speed (for example, 25 km / hr). O
N is a contact that is turned off when the vehicle speed exceeds the set speed, 3 is a contact that is turned on when the accelerator pedal is released, and is turned off when the accelerator is stepped on, 4 is a blinker, and 5 is a warning light. 6 is ON for normal operation, OFF for automatic constant-speed traveling operation, and ON for cancellation of automatic constant-speed traveling operation, 7 is ON when the brake is depressed,
It is a contact that turns off when you release your foot.

In implementing the present invention, in addition to the blinking lighting by the blinker 4 in the above example, a continuous point is excluded except the blinker 4.
May be as light, also as a warning lamp 5 is control Doto only Also
Not only turn on the tail lights only, but
May be flashing lights or continuous lighting when.

[0007]

According to the present invention, when the engine is started by turning on the operation switch of the car, the contact 1 is turned on, and the contact 3 is on until the accelerator is depressed. When the accelerator is pressed for starting, the contact 3 is turned on. It turns off, but contact 2 is on until the speed of the car that has started reaches the set speed, so current flows to contact 1, contact 2, blinker 4, and warning light 5 and blinks ( flasher 4 is turned on). When the vehicle speed exceeds the set speed, the contact 2 is turned off and the lighting is stopped and the warning to the following vehicle is stopped.

When the vehicle speed falls below the set speed due to the slow running before crossing the pedestrian crossing or the intersection stop line during traveling, the contact 2
Or initiate a warning to following vehicles continuously lit lights flashing ON and warning light 5 again. When the front confirmation is completed or the signal becomes a progress signal and you step on the accelerator to start the vehicle, contact 3 turns off, but until the vehicle speed reaches the set speed, contact 2 is on Light 5 blinks
When the vehicle speed exceeds a set speed, the contact 2 is turned off and the lighting is stopped to stop the warning to the following vehicle.

When the vehicle decelerates by releasing the accelerator pedal during high speed operation while the speed exceeds the set speed, the contact 3
Is turned on, the warning light 5 blinks or lights continuously to start a warning to the following vehicle, and when the deceleration operation state is canceled by depressing the accelerator to exceed the acceleration state or the constant speed operation, the contact 3 is turned off. If the vehicle speed at that time is not less than the set speed, the contact 2 is also OFF, so the warning lamp 5
Flashing or continuous lighting will stop and the warning to the following vehicles will be stopped.

Next, in the case of normal operation, the contact 6 is ON. Therefore, when the vehicle is decelerated by releasing the foot from the accelerator during medium speed or high speed operation exceeding the set speed, the contact 3 is turned ON.
The warning light 5 will continue to blink even if you do not press the brake.
Others begin a warning to the following vehicles and continuous lighting. However, when the automatic constant speed running operation is set, the contact 6 is turned off, and the warning lamp 5 is not turned on during the automatic constant speed operation even if the contact 3 is turned on by releasing the foot from the accelerator. Further, in the case of normal operation can be achieved by setting the automatic constant speed running operation when stepping on the brake, a warning to the prior art and the contact 7 is turned ON warning light 5 similar flashing lights or continuous lights to following vehicles First, when you release your foot from the brake, the warning light 5 will blink and light up.
Or, the continuous lighting is stopped and the warning to the following vehicles is stopped.

[0011]

Since the device of the present invention utilizes the above-mentioned action produced by the above-mentioned means, it is not only necessary to simply press the brake on the following vehicle to start the braking, but also the low speed operation or the deceleration operation. Even in this state, the warning light starts blinking or lights continuously to notify the following vehicle of the deceleration condition before braking in advance, so there is no rear-end collision in this driving state. Has a great effect, and its ripple effect is also extremely large.
