Abstract

The invention discloses a virtual display system of a front shield for reversing scenes. The virtual display system comprises a reversing radar (3), a gear operating lever (5), a vehicle-mounted computer (9), a connecting wire and an imaging display system, wherein the imaging display system mainly comprises a front windshield (1) and a display screen (2); the front windshield (1) consists of two pieces of common glass (6) between which a PVB (Poly Vinyl Butyral) middle film (7) is arranged; and the display screen (2) is embedded between the PVB middle film (7) and the common glass (6). The virtual display system disclosed by the invention has the advantages that due to adoption of the technical scheme, by a method of embedding the display screen into the front windshield, the vision of the front windshield of a vehicle is fully utilized, so that the action of the head of a new driver for observing a rearview and the reversing radar in a reversing process is reduced, and convenience is brought for the reversing operation of the driver.

Description

Shelves screen virtual display system before a kind of reversing scene

Technical field

The present invention relates to a kind of automotive front baffle screen virtual display system.

Background technology

Traditional reversing automobile safety method is divided into mirror field of view improvement technology, reversing aid system and three kinds of technology of intelligent parking technology.The former two is devoted to expand the chaufeur reversing visual field, cleaning backsight blind area, and last a kind of technology is to pay close attention to vehicle when specified low speed driving, can intelligent automation finds the intelligent use of parking space aspect.

Current mirror field of view improves technology, mainly for the design improvement to rear-vision mirror face, comprise plane mirror, spherical mirror, variable curvature minute surface, combination minute surface etc., all kinds of minute surfaces also respectively have merits and faults, though for example plane mirror can guarantee that imaging is undistorted, but there is larger blind area, limited driver's seat; And spherical mirror is on the contrary, cleaning but cannot guarantee that imaging is undistorted in the time of blind area; Though variable curvature minute surface and combination minute surface can solve the problem that first two minute surface exists, and still can not make reversing more intuitively convenient, still need chaufeur to possess certain experience to the operation of back mirror, just can accurately judge.

Compare mirror field of view improvement technology, reversing aid system technology is also used rather widely in current reversing automobile field, and what know the most is many appearance and application for Reverse Sensor.Reverse Sensor, at present just towards the future development of image conversion, can more get information about the various situations of rear view of vehicle while making chaufeur reversing, but various product location differs, and causes accuracy and economy to differ, and price even can differ several times.Simultaneously due to the screen size restriction of trailer-mounted radar, the driving directly perceived still can not be when normally travelling while making chaufeur reversing.And Intelligent parking system is due to its complicated sensor placement and high cost, it can only be present in a large amount of high-grade cars and use, and due to technical reason, most of Intelligent parking system also can only be realized S. A. and independently stop.

Summary of the invention

The object of the invention is that the visual field is limited in order to overcome in above-mentioned prior art, image fault, driving intuitively do not provide a kind of reversing effect virtual display system intuitively.

The present invention's shelves screen virtual display system before scene of moveing backward, comprise Reverse Sensor 3 that can inspection vehicle obstruction, control the gear position operation bar 5 of working state of monitor and accept the detection signal of Reverse Sensor 3 and be translated into image vehicle-mounted computer 9, connect wire and imaging display system.

Described imaging display system mainly consists of front windshield 1 and read-out 2; Described front windshield 1 is comprised of two blocks of simple glasses 6, is provided with to take the PVB intermediate coat 7 that polyvinyl butyral is main component between described simple glass 6, and described read-out 2 is embedded between PVB intermediate coat 7 and simple glass 6.

Described connection wire is all-transparent wire 4, adopts all-transparent wire can not affect driver and crew's sight line, and described all-transparent wire 4 one end are connected in read-out 2, and the other end connects vehicle-mounted computer 9.

Described read-out 2 is LCDs, and section thickness is 1-2mm, is of a size of 14 inches, is positioned at the lower left corner of front windshield 1, is positioned at the visual dead ahead of chaufeur.

When gear position operation bar 5 hangs over reverse gear position, the mode of operation of read-out 2 in showing, read-out 2 shows after Reverse Sensor detects, the image after vehicle-mounted computer transforms; When gear position operation bar 5 is hung on the position of the gear that normally travels, read-out 2 is in off-position.The virtual image of described read-out 2 interior demonstrations matches with wheel steering is same.

Adopt technical scheme of the present invention by embed the method for read-out in front windshield, take full advantage of the visual field of vehicle front windshield, reduced and driven the headwork of observing side mirror and Reverse Sensor when new hand moves backward, facilitated the car backing operation of chaufeur, reduce the feared state of mind that chaufeur causes because reverse action is unskilled, the loss of time and vehicle damage, also improved safety and the Driving of vehicle backing.The principle triggering according to reverse gear, has avoided the false triggering of this system, and while also effectively avoiding normal vehicle operation, screen mistake shows the interference in the visual field and hidden danger that driving safety is brought.

The specific embodiment

Below in conjunction with accompanying drawing, for specific embodiments of the invention, be described further.

As shown in Figure 2, virtual image front windshield 1 adopts pairglass design, by two blocks of simple glasses 6 and press from both sides between simple glass 6 into one deck and take the PVB intermediate coat 7 that polyvinyl butyral is main component, this PVB intermediate coat has good cohesiveness to unorganic glass, can be by glass 6 molding bondeds.

As shown in Figure 1, position, the lower left corner at Windshield 1, the LCDs 2 of one 14 inches of left and right is settled in the position, the visual field that is operating seat front side, read-out 2 is embedded between PVB film 7 and glass 6, its section thickness 1-2mm, periphery connects by all-transparent wire 4, and all-transparent wire 4 ends are connected to vehicle-mounted computer 9 terminals.

When before reversing scene, shelves screen virtual display system is worked, be that gear operating lever 5 hangs over reverse gear, trigger read-out 2, read-out 2 energisings, realization gathers with vehicle-mounted computer 4 and processes the demonstration of automobile rear image later in read-out 2 through Reverse Sensor 3, when joystick is hung on while normally travelling gear, remove demonstration read-out 2 power-off of read-out 2, thereby it is only just in running order when driver hangs reverse gear or reversing to realize read-out.

When in running order when middle, chaufeur just in face of shelves glass in read-out 2, shown is the virtual image of rear view of vehicle road conditions and scenery, and the coordinating in the same way of realization and chaufeur wheel steering, when chaufeur reversing is turned left, what experience is to be similar to the vehicle experience that just row turns left, the other parts of while windshield 1, and the apparent area of removing outside telltale 8 normally shows vehicle dead ahead road conditions and scenery.
