Abstract

PURPOSE: A vehicle instrument board information display unit is provided to promote safety in driving without being hindered in concentrating driver's attention forward. CONSTITUTION: In a vehicle instrument board information display unit, an analog instrument displays an output signal converting a speed meter signal(12), a tachometer signal(14), a fuel gauge signal(16), or a coolant thermometer signal(18) into digital signals through an A/D converter circuit(10). A digital instrument board displays an output signal converting the speed meter signal, the tachometer signal, the fuel gauge signal, or the coolant thermometer signal into such digital numbers as a segment and a dot matrix not through the A/D converter circuit or shows by a diagram of a graph type in proportion to the input signal value, and indicates on a display(8) with a transparent background. A right and left rotation signal(20,22) or an alarm or indicator signal(24) is converted into a digital signal and the output signal is shown by a diagram and indicated on the display with a transparent background installed to a front window. Therefore, operating information is given to a driver without being hindered in a field of vision of the front window.

Description

Vehicle instrument panel information display {Display device for driving information}

The present invention is to display the information of the instrument panel on the front window side in the vehicle to check the information of the instrument panel during operation of the vehicle by installing a display having a transparent background characteristics on the front window of the driver's seat and confirming the information of the instrument panel displayed on the display The present invention relates to a driving information perspective device that realizes safe driving by securing a forward field of view by allowing a driver to check the contents without turning his view to check the instrument panel during driving.

The dashboard of a conventional vehicle is in the downward position in front of the steering wheel, so if the contents of the instrument panel (speed, engine speed, fuel level, coolant temperature, left and right turn signals, other warnings) need to be checked, the driver's gaze can Since it is necessary to move downward to the instrument panel, there is a problem that there is a risk of accident at all times while not recognizing the rapidly changing traffic situation while searching for information on the instrument panel.

In addition, the vehicle is operated without checking the information on the instrument panel during operation, so it is not confirmed that various indicators and warning lights (oil pressure warning lamp, charging warning lamp, engine maintenance indicator lamp, etc.) are turned on, which may be a dangerous factor for the safe operation of the vehicle and also the change of direction. Not knowing that the indicator lights or emergency warning lights are turned on, which may cause a misbehaving signal to other vehicles, causing traffic accidents.

Accordingly, the present invention is invented to improve the problem of the conventional instrument panel of the vehicle, a display installed on the front window of the vehicle by converting the information of the vehicle instrument panel into a digital signal (the display itself has a characteristic of a transparent background display It is an object of the present invention to provide a means for promoting safe driving without being obstructed to focus on the front view by looking through the (to be able to observe the foreground outside the vehicle front window through).

The present invention for realizing the above object is to collect the information provided on the instrument panel of the vehicle input unit and the conversion unit for converting the input analog signal into a digital signal and an output signal suitable for the display device It is made to be sent to the display drive circuit to be generated and the combat against the background display installed in the front window of the vehicle.

Hereinafter will be described in detail with respect to the configuration and operation effects based on the accompanying drawings.

First, the circuit function will be described as follows.

The terminal unit 2 serves to provide an input signal of the conversion unit 4 in connection with a signal provided to the instrument panel of the vehicle.

The converting unit 4 converts a signal of the instrument panel input from the terminal unit 2 so as to be suitable for the display drive circuit 6. In this case, in the case of the analog instrument panel, a speed meter signal 12 is applied. And a tachometer (engine speed indicator) signal 14, fuel gauge signal 16, and coolant thermometer signal 18 are converted into digital signals through an A / D converter (analog-to-digital converter) 10 circuit. Input to the circuit 6.

The turn signal 20 and the right turn signal 22 and other warning lights and indicator signals 24 are converted into digital signals to be suitable for the display drive circuit 6 and input to the display drive circuit 6.

In addition, other warning lights or indicator lights 24 are connected to the common alarm signal (multiple warning light input signals (e.g. coolant temperature warning, door open warning, low oil pressure warning, charging warning light) via logic circuits (OR, NOR). , When one or more signals of an engine maintenance warning lamp, etc. are inputted, one output signal is generated) and the output signal is provided to the display drive circuit 6.

The display drive circuit 6 receives the output signal of the converter 4 and outputs it in the form of a segment or a digital number of a dot matrix so as to be suitable for display on the transparent background display 8, or in the form of a graph proportional to the output signal value. Or, the signal is converted to be displayed in the form of an indicator corresponding to the input signal to output to the transparent background display (8).

The transparent background display 8 is composed of a see-through LCD or a transparent glass light emitting device for a smart window. The transparent background display 8 receives an output signal of the display drive circuit 6 and displays the display signal in a form that is easily recognized by the driver. Background display (8) has the characteristics of the transparent display itself, so that you can observe the foreground of the front window 26 through the display and the frame and the support is also made of a transparent material in the front view due to the display installation It is not an obstacle.

The function of the above circuit is explained by dividing by signal type as follows.

Speed meter signal 12, tachometer (engine speed indicator) signal 14, fuel gauge signal 16, coolant thermometer signal 18, A / D converter (analog to digital converter) circuit 10 When the digital signal is converted into a digital signal and input to the display drive circuit 6, the display drive circuit 6 displays the signal in the form of a segment, a digital number of a dot matrix, or a graphic so that the value according to the output can be plotted. Is converted and the output signal is displayed on the transparent background display (8).

The turn indicators left and right turn signals 20 and 22 are converted into digital signals by the converter 4 and the output signals are graphically displayed on the transparent background display 8 through the display drive circuit 6.

The input signal 24 of the warning light indicator is output as a common alarm signal through a logic circuit, and the output signal is graphically displayed on the transparent background display 8 through the display drive circuit 6.

In the case of a digital instrument panel, the speedometer signal 12, tachometer signal 14, fuel gauge signal 16, and coolant thermometer signal 18 may be transferred to the display drive circuit 6 without passing through the A / D converter circuit 10. Let the user enter it manually.

When it is necessary to check the contents of the conventional instrument panel, the driver's gaze moves downward from the road situation outside the front window to the instrument panel and solves the problem of not recognizing the rapidly changing traffic situation while searching for information on the instrument panel. It is not possible to confirm that the warning lamp (oil pressure warning lamp, charging warning lamp, engine maintenance indicator lamp) is lit or not to turn on the turn signal or emergency warning lamp and thus to send a wrong signal to another vehicle. have.

Therefore, the present invention can implement the safe driving by ensuring the front field of view by allowing the driver to check the contents while viewing the road situation without turning the field of view to check the conventional instrument panel while driving the vehicle.
