Description

The autocontrol method to the headlight corresponding to illumination and speed {The autocontrol method to the headlamp & taillamp for automobile}

The present invention is an automatic lighting control device that automatically controls the headlights and taillights according to the change in the brightness level (brightness) of the surroundings and the driving speed of the vehicle to operate the lights appropriate to the driving situation, thereby improving safety driving and convenience of driving.

Various lighting devices mounted on a vehicle are installed to be used as a means for safe driving, but since they are not effectively used at the appropriate time, safe driving is not guaranteed and threatens pedestrian safety. In order to use the lighting device for the purpose of safe driving, the driver has to operate a large number of light switches depending on the driving environment even during the daytime, and it is very troublesome. Most drivers rarely use equalization during the day because of the uncomfortable cases of discharge.

Accordingly, the present invention provides equalization suitable for the driving situation according to the change of the illumination and the speed of the vehicle according to the change of weather and the time, even at high illumination during daytime as well as night driving which requires the lighting even if the driver does not operate the light switch. It is an auto-lighting method of the automobile corresponding to the illumination and the speed that was invented for the purpose of promoting the safe driving and improving the convenience by effectively controlling the vehicle automatically.In particular, the headlights and taillights are turned on and off according to the speed change of the vehicle. It is to provide a means for automatic control.

Although many methods have been known in the prior art for the automatic lighting of automobiles, some conveniences have been improved in the results, but they are not suitable for the purpose of equalization for the purpose of safe operation. Technology could not be utilized.

Accordingly, the inventors have invented an automatic equalization method corresponding to illuminance and speed as a method for automatically controlling the lighting suitable for the driving environment in the daytime operation as a means for promoting safe operation as well as automatic control in night operation.

Conventionally known auto lighting means for vehicles detect irradiance (light brightness) of the driving environment regardless of the driving speed of the vehicle, set the automatic control level, and then set the illuminance level according to the degree of illumination change. In the following, a method of performing auto-lighting has been used, and on the other hand, a convenient means for detecting the starting and stopping states of the vehicle and automatically controlling the headlights with the light switch on regardless of the illumination level is known. Means for the automatic control of a combination of the two methods are known, but in the method of automatically controlling the equalization by setting the illumination level, all of the known methods detect the set illumination change and automatically control the equalization below the set illumination level. Will be provided.

The conventionally known means as described above could be used as a useful method at dawn, evening, and night operation, but automatic lighting according to the change of weather and the speed of the vehicle in daytime operation could not be realized. In other words, for safe driving, even in daytime driving, lighting is required according to the driving environment and timing. When the illumination level is changed to automatic control condition as in the conventional means, the illumination is much higher than the illumination of the lighting time of the everyday evening. Even on sunny days, cloudy days, rainy days, and sunny days, it is not possible to use automatic control of equalization as a means to clarify the identification of vehicles by changing the amount of sunshine and the change of sunshine. .

Accordingly, in order to solve the conventional problems as described above and effective automatic equalization for safety, there is a need for a method capable of automatically controlling the equalization even at high illumination.

The present invention is to solve all the problems of the prior art by providing a method different from the conventional method in which the change in the illumination level is a condition of automatic control in the automatic control of the equalization of the vehicle. The present invention provides a method for automatically controlling the equalization of a vehicle even when a driver does not use a light switch while driving a vehicle by using a change in the vehicle's driving speed as a condition of automatic control.

Various lighting devices mounted on the car can be used as a means of preventing accidents in the daytime operation as well as for the purpose of safety at night, and during the daytime operation, most drivers do not use the lights for various reasons. It is a way to technically solve what is causing the problem.

As an automatic control method of lighting to achieve the object of the present invention as described above, the range of auto-lighting and off-time of lighting is selected by changing the illumination level in a normal driving environment of a vehicle and controlling the change of driving speed. As a control means, it is possible to control the taillights and headlights suitable for the driving environment according to the speed change, and to change the level of illuminance used as a comparison condition to perform effective equalization according to the change of weather and timing in daytime operation. According to the present invention, a means for dividing the speed control range into each stage is provided, and each stage constituting the speed control range is provided with means for separating the operation level of the tail light and the headlight, respectively, so that the headlight and the tail light are independently controlled. In addition, the lighting turns on automatically when driving at a higher speed than the set auto lighting speed. And, it is the accomplishment of the automatic equalization method corresponding to the vehicle speed and the roughness, characterized in that comprises a means that is automatically turned off when the deceleration below the auto-off speed set by providing.

At this time, the illuminance level of each step of selecting the speed control range as a method for satisfying all the conditions of the normal driving situation is classified into the lowest illuminance level during the night driving step by step and according to the change of the speed. In the vehicle speed range of each stage that controls the equalization, the lower the illuminance is, the automatic control timing due to the change of the vehicle speed is set to the lower speed range. On the contrary, if the illuminance is changed high, the automatic equalization is performed in the high speed range over the set speed. Speed control range selected by illuminance level to enable automatic lighting at high speed even at the maximum illuminance on a clear day, and automatic lighting at the same time as vehicle starts at minimum illuminance at night without any lighting. In the taillights and headlights is characterized in that it is automatically controlled.

An embodiment of the present invention having the features as described above will be described in detail with reference to the accompanying drawings.

In the accompanying drawings, Figure 1 is a block diagram illustrating the means according to the present invention, Figure 2 is a first step of the control range setting step, even if the vehicle is stopped after the taillights are turned on at the same time as the initial start of night driving Fig. 3 is a block diagram illustrating a means for preventing the taillights from turning off, and Fig. 3 is a means for configuring a control range setting step except for the first step, and each control sets the illumination level and the speed control range in different ranges. This section describes the basic structure of one step.

As shown in FIG. 1 of the accompanying drawings, the auto equalization method of a vehicle corresponding to the illuminance and speed of the present invention is configured as follows.

The control range setting step 30 according to the present invention comprises a first step 31, a second step 32, a third step 33, and a fourth step 34 which set different control ranges. Each stage receives two input signals, that is, the illumination signal and the vehicle speed signal, and separates the control output signals of the taillights and the headlights according to the control range set in each stage so that the taillights and the headlights are controlled separately.

In this case, the control range setting step 30 is connected to the illumination signal input and the vehicle speed signal input, and the tail light output and the headlight output of each stage in parallel, respectively. After the branch input and the two outputs are configured, the illuminance signal input is connected to the output of the illuminance signal conversion step 20 which converts the illuminance change into a control signal, and the illuminance of each step constituting the control range setting step 30. Supply the same signal to the signal input.

The illuminance signal conversion step 20 converts the illuminance change detected by the optical sensor 10 into an electrical signal that can utilize the control signal, so that an output proportional to the illuminance change is generated.

Accordingly, the signal of the same level as that of the output of the illuminance conversion step 20 is supplied to the illuminance signal input of each step constituting the control range setting step 30, and the control range setting step 30 is according to the level of the signal. Make sure that one step of each step is selected.

On the other hand, the vehicle speed signal input of the control range setting step 30 is connected to the output of the band setting step 80 for converting different output signals to the same signal according to the type of the vehicle speed sensor 70, the control range setting step 30 The same signal is supplied to the vehicle speed signal input of each step constituting the circuit.

The band setting step 80 is a means for preventing the vehicle speed control range from being changed by generating a different signal according to the type and characteristics of the vehicle speed sensor 70 and converting the output signal of the vehicle speed sensor into a constant frequency change to the vehicle speed. Causes proportional output to occur.

Accordingly, the same signal as the output of the band setting 80 is supplied to the vehicle speed signal input of each step constituting the control range setting step 30, and at each step of the control range setting step 30 in accordance with this signal. The tail and headlights are turned on and off in the set speed range.

It is supplied to the tail light control setting step 132, and outputs the headlight control signal in the minimum speed range set after the output of the tail light control signal to be supplied to the vehicle speed signal input of the first headlight control setting step 135.

At this time, when the vehicle starts and the vehicle speed signal is output, the output signal of the first tail light control setting step 132 is formed, and the tail light is turned on immediately, and the tail light speed canceling step 133 is operated by this signal to set the first tail light control setting. In step 132, the tail light does not go out even when the vehicle is stopped and the vehicle speed signal is not supplied.

On the other hand, the headlight after the taillight is automatically turned on, when the speed of the vehicle reaches the minimum speed set by the vehicle speed input signal of the first headlight control setting step (135) is supplied with the output is formed and automatically lights up when the vehicle stops It is automatically turned off when the vehicle speed input signal is blocked.

Since the second step 32, the third step 33, and the fourth step 34 of the control range setting step configured as shown in FIG. 3 do not have the taillight speed cancellation 133 means of the first step of FIG. The taillight is automatically turned off at the speed below the minimum speed.

In the illumination level setting 136 of each step, the speed control range is selected at the corresponding illumination level, and the automatic control ranges of the taillights and the headlights are performed at low speed in the illumination at dawn and evening and the daytime illumination at very cloudy days. In the third stage 33, which is higher than the second stage 32 and the second stage illuminance, and the infinity illuminance during the day, the fourth stage 34 controlling according to the driving speed of the vehicle is selected.

On the other hand, in the vehicle speed signal separation step 138 of each stage, the taillight control signal and the headlight control signal are separately outputted so as to separately control the lighting time and the lighting time of the tail light and the headlight according to the change of the vehicle speed, and thus the vehicle speed. Is accelerated to above the set speed, the taillight is turned on first, and then the headlight is turned on when the vehicle speed is further accelerated.If the headlight is decelerated below the set speed, the headlight is turned off first and then the taillight is turned off. It is.

The taillight control output of the control range setting step 30 is connected to the taillight control 40 step to control the taillight relay 50 of the vehicle's equalizer 130 and to operate in parallel with the vehicle's light switch 120. Control the taillight 60, the headlight control output is connected to the headlight control (90) stage to control the headlight relay 100 of the vehicle's lighting device 130 and operate in parallel with the vehicle's light switch 120 The headlight 110 is controlled so that the lighting is automatically controlled by means of the present invention when the light switch 120 of the vehicle is turned off. The existing light switch 120 installed in the vehicle is controlled. The function of is to be used in parallel together.

When the vehicle is started at the beginning of night driving by the action of the present invention configured as described above, the tail light and the headlight are not turned on, the tail light is automatically turned on as soon as it starts, the headlight is automatically turned on when the minimum speed range is reached, and the tail light is temporarily stopped. It will stay on and the headlight will turn off automatically.

In low light, automatic control is performed at low speed. As the light intensity increases, automatic control is performed in the high speed range, so that auto-lighting can be performed even during the day, and automatic control when the light switch is OFF. If the light switch is set to ON, the automatic control function is lost and operated manually.
