Abstract

The invention relates to a front backup scene virtual display system achieving forward-direction backup of vehicles. The display system comprises front windshield glass, a liquid crystal display screen, a backup radar and a vehicle-mounted computer. The liquid crystal display screen is located right ahead of a driver visually seeing and is embedded in the front windshield glass. According to the method, the display screen is embedded in the front windshield glass, front windshield visual fields of vehicles are sufficiently utilized, head motions of a driving green hand observing rearview mirrors and the backup radar when the driving green hand backs up are reduced, backup operation of drivers is facilitated, fighting fear, time loss and vehicle damage caused by unskilled backup motions of the drivers are reduced, and backup safety and driving joy for the vehicles are also improved. According to the reverse gear triggering principle, false triggering of the system is avoided, and disturbance on the visual fields due to wrong indications of the screen and hidden dangers brought to driving safety when the vehicles run normally are also effectively avoided.

Description

A kind of preposition reversing scene virtual display system

Technical field

The present invention relates to a kind of preposition reversing scene virtual display system that is, realize the forward reversing of vehicle.

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, energy intelligent automation is found 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 is at present just towards the future development of image conversion, be can more get information about the various situations of rear view of vehicle during chaufeur reversing, but various product location differs, and causes accuracy and economy to differ, 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

1. technical matters to be solved

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 scene virtual technique of display and forward backing method intuitively.

2, technical scheme

The invention provides the virtual technique of display of a kind of preposition reversing scene, comprise front windshield, LCDs, Reverse Sensor, vehicle-mounted computer, LCDs is positioned at the visual dead ahead of chaufeur, is embedded in the middle of front windshield.

3, beneficial effect

The present invention by embedding 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.

Accompanying drawing explanation

Fig. 1 is the three-dimensional structure diagram of virtual image front of the present invention.

Fig. 2 is the position schematic diagram of read-out 2 on front windshield 1 in Fig. 1.

System flowchart when Fig. 3 is this system operation.

In figure: 1. front windshield; 2,8. read-out; 3. Reverse Sensor; 4. all-transparent wire; 5. gear operating lever; 6. simple glass; 7.PVB intermediate coat; 9. vehicle-mounted computer.

The specific embodiment

As shown in Fig. 2 (lateral plan), virtual image front adopts pairglass design, there are two blocks of simple glasses 6, between simple glass 6, adding one deck presss from both sides into one deck and take the PVB intermediate coat 7 that polyvinyl butyral is main component, and in the position, the visual field of operating seat front side, settle the LCDs 8 of one 14 inches of left and right, read-out 8 is embedded between PVB film 7 and glass 6, its section thickness 1-2mm, periphery connects by all-transparent wire, and wire end is connected to vehicle-mounted computer 9 terminals.

When the present invention works, be that gear operating lever 5 hangs over reverse gear, trigger 8 energisings of read-out 8(read-out), realization gathers with vehicle-mounted computer 4 and processes the demonstration of automobile rear image later in read-out 8 through Reverse Sensor 3, when joystick is hung on while normally travelling gear, remove the demonstration (read-out 8 power-off) of read-out 8, 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 8, 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, and the other parts (removing the apparent area outside telltale 8) of windshield 1 normally show vehicle dead ahead road conditions and scenery simultaneously.

Claims
