Abstract

PROBLEM TO BE SOLVED: To provide an initial-flashing-type brake pedaling indicator that can improve a visual warning recognizing function of a driver of a following vehicle by driving brake lamps with two kinds of dynamical and static signals that continue over time, and can certainly prevent collision accident.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an initial flashing type brake depression display device which can be used as an alarm device for preventing a rear-end collision of an automobile or the like.

[0002]

2. Description of the Related Art Conventionally, in an alarm device used for the above-mentioned application, a brake depression switch is closed when a brake is depressed, and a brake lamp provided at a rear portion of a vehicle, for example, is shut down based on the closing signal. It lights up continuously or continuously, and statically conveys to the following vehicle an intention to stop the preceding vehicle to perform a stop operation.

[0003]

However, in such a conventional alarm device, since the lighting of the brake lamp is static, the effect of giving a warning to the human visual recognition is small, and the driver of the following vehicle has a problem. The driver sometimes overlooked the brake pressing operation of the vehicle ahead, which caused a collision accident. SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and by driving a brake lamp with two types of signals, which are continuous in time, dynamic and static, a visual warning of a driver of a following vehicle is provided. Can improve the recognition function,
An object of the present invention is to provide an initial flashing type brake depression display device which can surely prevent a collision accident or the like.

[0004]

According to a first aspect of the present invention, there is provided an initial blinking type brake depression display device for achieving the above-mentioned object. It is characterized by having a brake lamp that lights. In order to achieve the above-mentioned object, an initial blinking type brake depressing display according to a second invention is provided.
A brake depression switch, a pulse generation circuit and a pulse delay circuit that are driven based on an output signal of the brake depression switch, a drive circuit that performs a logical sum operation of the pulse generation circuit and an output signal from the pulse delay circuit, A brake lamp that performs a blinking operation initially based on an output signal of the driving circuit, and then performs stationary lighting.
With the above-described configuration, when a driver performs a brake operation, a brake depression switch that is closed in conjunction with the brake operation operates to drive a pulse generation circuit and a pulse delay circuit. The drive circuit 4 performs a logical OR operation of the signals from these two circuits, blinks the brake lamp 5 initially to perform dynamic lighting, and then continuously lights up to perform stationary lighting.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; First, a description will be given of an initial flashing type brake depressing display according to the present embodiment with reference to FIG. 1. A step-down switch 1, a pulse generating circuit 2 and a pulse delay circuit 3 driven based on an output signal of the brake step-down switch 1, and a logical sum operation of output signals from the pulse generating circuit 2 and the pulse delay circuit 3 And a brake lamp 5 that performs a flashing operation initially based on an output signal of the drive circuit 4 and then performs stationary lighting.

Next, the operation of the initial flashing type brake depressing display device having the above-described configuration will be described with reference to FIG. FIG. 2 is a timing chart showing the operation of each component with the passage of time, where the higher part of the waveform is the on state of the brake lamp 5 and the lower part is the off state. When the driver performs a brake operation, a brake depression switch 1 that is closed in conjunction with the brake operation operates to drive a pulse generation circuit 2 and a pulse delay circuit 3.
As a result, the pulse generation circuit 2 generates pulses intermittently, and the pulse delay circuit generates continuous pulses with a certain delay. Then, the drive circuit 4 performs a logical OR operation of the signals from the pulse generation circuit 2 and the pulse delay circuit 3, and based on the logical OR signal, blinks the brake lamp 5 initially and performs dynamic lighting. After that, the lighting is continuously performed to perform the stationary lighting.

At this time, the pulse generation circuit 2 adjusts the pulse period so as to maximize the visual warning effect on humans. Further, the delay time of the pulse delay circuit 3 is adjusted so as to be an optimum value for switching from dynamic blinking to static lighting in relation to a normal one-time brake pressing time. As described above, in the present embodiment, based on the brake operation by the driver, the brake lamp 5 is initially turned on and off to perform dynamic lighting, and then continuously turned on to perform stationary lighting. Thus, the function of visually recognizing the driver of the following vehicle can be improved, and a collision accident or the like can be reliably prevented. In addition, the blinking operation was performed only in the initial stage, and after that, continuous lighting was performed as in the past,
It is possible to reliably prevent the driver of the following vehicle from erroneously recognizing that the direction indicator lamp has blinked.

Although the present invention has been described with reference to an embodiment, the present invention is not limited to the above-described embodiment. Alternatively, the portion of the brake depression switch may be connected to both ends of the terminal of the existing brake lamp that performs a static operation.

As described above, the present invention focuses on the fact that human vision responds to a dynamic blinking warning signal more highly than a static warning signal, and focuses on braking by a driver. Based on the operation, the brake lamp flashes dynamically at the beginning and performs dynamic lighting, and then continuously lights to perform stationary lighting, so that the driver of the following vehicle can brake the front vehicle faster. In addition, the vehicle can be recognized accurately, and a car accident such as a rear-end collision can be prevented.
