Screen display rearview mirror system
The invention belongs to the technical field of automobile interactive control, relates to a rear view display system for replacing an inner rear-view mirror, and particularly relates to a display screen rear-view mirror system.
The inside rearview mirror is a plane mirror and reflects the real distance behind the vehicle. When the inner rear-view mirror causes the outer rear-view mirror to receive influence when driving the vehicle to overtake, change lane, emergency brake and part of severe weather, the inner rear-view mirror can help the driver to observe road condition information behind the vehicle, judge the distance with the object behind the vehicle and avoid driving accidents.
The automobile inner rear-view mirror is divided into 3 types: 1. a manual anti-glare rearview mirror; 2. automatic anti-glare rearview mirrors; 3. streaming media rearview mirror. Dazzling is generally when driving at night, and the car light of rear vehicle shines interior rear-view mirror surface, reflects people's eyes, leads to the driver night blindness, and the light source disappears in time, also can make driver's eyes residual image appear, reduces driver's reflection time, brings great driving accident risk. The manual antiglare principle is to suppress the occurrence of glare by an optical principle. There is the lens angle modulation pole on the manual anti-dazzle mesh interior rear-view mirror, its lens is an about 10 wedge prism, the thickness ratio of lens top is bigger than the lower extreme, under the general state, the surface of rear-view mirror formation of image gets into eyes after the coating film refraction at lens back, it is the same with ordinary level crossing imaging principle, after the angle modulation pole was pulled anti-dazzle mesh state, whole lens can upwards adjust about 10, at this moment, light can reflect people's eye formation of image through the semi-permeable coating film euphotic layer on the lens, refraction to light is lower, reach anti-dazzle mesh effect. The automatic anti-dazzle inner rear-view mirror is characterized in that a photosensitive diode is arranged behind a mirror surface, when the diode senses strong light, a control circuit applies voltage to an ionized layer of the mirror surface, a lens becomes dark under the action of the voltage to achieve the anti-dazzle purpose, the automatic anti-dazzle inner rear-view mirror can prevent dazzling, when the automobile backs from a garage, the light at the back of the automobile is strong, the light at the front of the automobile is weak, at the moment, the rear-view mirror is not beneficial to seeing the situation behind the automobile when the automobile backs due to the fact that the light at the back of the automobile is dark, and therefore some automobiles can be designed to automatically cancel the anti-dazzle function when the automobile is in a reverse. The stream media rearview mirror combines the function of a camera with the traditional inside rearview mirror by using a real-scene display technology, and projects real-time real-scene images behind a vehicle on a mirror surface. The system has the advantages that the visual range of the traditional inside rearview mirror is greatly improved, the safety of driving and parking is facilitated, and the streaming media rearview mirror can also integrate multiple functions of navigation, a driving recorder, backing images, entertainment information display and the like. The problem that the rear-row passengers or the headrest blocks the view of the rearview mirror can be avoided.
The prior art has the following disadvantages
1. The inner rearview mirror occupies partial space of the car roof and shields the front view to a certain extent;
2. although the anti-glare rearview mirror is very popular, the anti-glare effect is limited, even if the mirror shell of the streaming media rearview mirror is dazzled, the rearview mirror cannot completely avoid dazzling;
3. for the common inner rear-view mirror, different drivers need to adjust different positions, and each driver cannot be directly matched in design
4. The more rearview mirrors with more functions, the more required equipment is, and the situation of rearview mirror shaking occurs in the driving process of a vehicle to influence the functions of the rearview mirrors;
5. when observing the inside rear-view mirror, the driver needs to leave the front temporarily, the attention of the driver is influenced, and potential safety hazards exist.
Disclosure of Invention
In order to overcome the above problems of the prior art, the present invention provides a rear view display system which replaces an interior rear view mirror; the problem that the observation of the inside rear-view mirror is realized to leave the front view field is solved, meanwhile, the space requirement of the rear-view mirror is saved, the shape and the front view field are improved, and meanwhile, the dazzling problem of the rear vehicle light is not required to be considered; the road condition information behind the vehicle is collected through the streaming media camera and displayed on a display screen of a windshield right in front of a driver.
The invention is realized by adopting the following technical scheme:
a screen display rearview mirror system is characterized by comprising a streaming media camera, a display screen and a wind window display controller, wherein the streaming media camera is arranged below a rear windshield of a vehicle, the display screen is a display element embedded in the front windshield of the vehicle or a film display screen pasted on the inner surface of the front windshield of the vehicle, the wind window display controller is arranged in the vehicle and connected with a power supply controller in the vehicle, and the streaming media camera and the display screen are both connected with the wind window display controller.
The further technical scheme is as follows:
the stream media camera adopts a camera with the waterproof performance of IPV6, the field angle of 80 degrees +/-10 degrees in the horizontal direction and 20 degrees +/-10 degrees in the vertical direction.
Compared with the prior art, the invention has the beneficial effects that:
the streaming media camera starts to work when a vehicle is started, information behind the vehicle is collected immediately, and the view field angle (the angle between the enveloping surface of the camera view field and the direction right behind the vehicle) is horizontal: 80 ° ± 10 °, perpendicular: the visual field is 5 times of that of a common optical rearview mirror at 20 +/-10 degrees, so that the lane behind the vehicle is completely covered, and a larger rear visual field can be provided; the waterproof performance of the camera is IPV6, the working performance is still not influenced under the condition of heavy rain, and the surface of the camera is not influenced by rain.
The air window display screen is air window glass capable of displaying image information, the display function is realized by embedding the display screen function on the air window glass or pasting a film display screen on the inner surface of the glass, and the position of the display area of the rearview mirror can be adjusted according to the driving habits of a driver, so that the rearview mirror meets the comfortable observation angle of the driver, the sight line is not moved away from the front view, and the driving safety is guaranteed.
The air window display controller can display the image collected by the streaming media camera to the display area of the air window display screen in real time, and supply power to the streaming media camera and the air window display screen, so that the rear view display system can work normally.
Fig. 1 is a schematic diagram of a position where a streaming media camera is arranged in the present invention.
Fig. 2 is a schematic view of the arrangement positions of the windshield display and the windshield display controller in the present invention.
