Problems solved by technology

The reversing radar is currently developing in the direction of graphics, so that the driver can understand the various situations behind the vehicle more intuitively when reversing. However, the positioning of various products is different, resulting in different accuracy and economy, and the price can even several times different
At the same time, due to the limitation of the screen size of the vehicle radar, the driver cannot drive as intuitively as when driving in reverse
Due to its complex sensor layout and high cost, the intelligent parking system can only be used in a large number of high-end cars, and due to technical reasons, most intelligent parking systems can only realize semi-automatic self-parking

Embodiment Construction

[0017] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 2 As shown, the virtual imaging front windshield 1 adopts a laminated glass design, and a layer of PVB interlayer film 7 with polyvinyl butyral as the main component is sandwiched between two pieces of ordinary glass 6 and the ordinary glass 6. The PVB The interlayer film has good adhesion to inorganic glass, and can bond and shape glass 6.

[0019] Such as figure 1 As shown, a liquid crystal display screen 2 of about 14 inches is arranged at the lower left corner position of the windshield 1, that is, the field of view at the front side of the driver's seat, and the display screen 2 is embedded between the PVB film 7 and the glass 6. The thickness is 1-2mm, and the periphery is connected by a fully transparent wire 4, and the end of the fully transparent wire 4 is connected to the terminal 9 of the on-board computer...

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

technical field [0001] The invention relates to a virtual display system of an automobile front shield screen. Background technique [0002] Traditional car reversing safety technology is divided into three technologies: rearview mirror vision improvement technology, reversing assistance system and intelligent parking technology. The first two are dedicated to expanding the driver's reversing field of vision and eliminating blind spots in the rear, while the last technology focuses on intelligent applications that can intelligently and automatically find parking spaces when the vehicle is running at a rated low speed. [0003] The current field of view improvement technology for rearview mirrors is mainly aimed at the design and transformation of rearview mirrors, including plane mirrors, spherical mirrors, variable curvature mirrors, combined mirrors, etc. Each type of mirror has its own advantages and disadvantages. For example, although a plane mirror can ensure that the ...
