Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a driving guide display device for an automobile that guides the destination of the automobile and facilitates rational driving.

Conventionally, this kind of driving guidance display device for automobiles did not exist, and the driver of the automobile drove to the destination using a compass, road signs, etc. as cues. Therefore, depending on the area where the vehicle is being driven for the first time, road conditions, etc., the vehicle may travel in a direction different from the destination, and the driver often travels in a detour. As a result, the time it took to reach the destination was significantly longer than planned, and there were times when it was impossible to complete the tasks at the destination ◇Furthermore, fuel was wasted significantly due to unnecessary driving, so it was necessary to drive rationally. In the worst case scenario, this could lead to a situation where the vehicle ran out of fuel, causing problems such as the inability of the vehicle to run.

The present invention has been developed to solve the above-mentioned problems.The present invention uses a display or the like to display the general direction in which the vehicle should travel to its destination, and the driver is directed to drive in the direction indicated on the display. The object of the present invention is to provide a new driving guidance display device for a motor vehicle that enables rational driving.

Hereinafter, an embodiment of an automobile driving guide display device according to the present invention will be described in detail based on the drawings.

The converter 4a is connected to the output side of the second integration circuit 3a, and the A/D converter 4b is connected to the output side of the second integration circuit 3b. The A/D converters 4a, 4b have the function of converting the analog signals from the second integration circuits 3a, 3b into digitizer signals. 5 is a drive computer, which is connected to the output side of the A/'D converters 4a, 4b.

Reference numeral 6 denotes a display device connected to the output side of the drive computer/speed controller 5. The display 6 is mounted on a panel near the driver's seat, for example, and can be a one-sided display that combines the shape of the car and a destination, or a dot matrix display that displays the current location and destination. Now, the operation of the automobile driving guide display device according to the present invention will be explained.

When the car starts traveling from the starting point, the X-axis direction impact sensors 1a and
The axial impact sensor 1b always operates and derives an acceleration signal.The first integration circuit 2a integrates the acceleration signal from the X-axis impact sensor 1b and converts it into a speed signal.The first and second integration circuits 3a 1 integrates the speed signal from the integrating circuit 2a and converts it into a distance signal.

This distance signal is an analog signal, and the A/D converter 4a
This digital signal is converted into a digital signal by the drive computer. On the other hand, the first integrating circuit 2b integrates the acceleration signal from the X-axis impact sensor 1a and converts it into a speed signal. The second integrating circuit 3b integrates the speed signal from the first integrating circuit 2b and converts it into a distance signal. This distance signal is an analog signal, and is converted into a digital signal by the Φ converter 4b. This digital signal is input to the drive computer 5.

In this way, the output signals from the X-axis impact sensor 1b and the X-axis impact sensor 1a are transferred to the drive computer 5.
The drive computer 5 performs counting operations and derives display signals. The display 6 is operated by a display signal from the drive computer 5 and displays the destination position of the automobile. For example, the display 6 may be configured to digitally display the horizontal and vertical distances from the current location to the destination to be traveled, clearly indicating the direction of travel of the vehicle, or may display a blinking destination point based on longitude and latitude using a graph or the like. Alternatively, there are devices that have a lighting display.

As described above, according to the travel guidance display device for a car according to the present invention, the display can accurately and clearly display the distance the car should travel from the starting point to the destination point, and the distance to the destination point can be reached without waste. A car can be driven rationally. This reduces bone fractures for the driver and makes driving more comfortable.

In addition, there is no wastage of fuel, and the inability to drive due to fuel exhaustion can be avoided.Furthermore, the present invention provides a high-quality driving guide display device for automobiles, which is composed of electronic components, is lightweight, and can be made into a single unit. There are various effects such as being able to
