Description
DRIVER ANTI-BLINDING SYSTEM
TECHNICAL FIELD
This invention relates to a vehicle fitted with an anti-glare (ant-blind) system to reduce the effects of glare from outside light sources into the face and eyes of the driver. It has particular but not exclusive application to preventing glare from headlights of oncoming vehicles.
BACKGROUND OF THE INVENTION
Currently on the market there is no system which prevents a driver of a vehicle being blinded by the light from headlights from oncoming vehicles i.e. opposite light sources. This occurs mainly at night but also when the outside light is bad due to clouds or bad weather. On coming vehicles often have long range/full beam lights turned on and undipped, or the headlights are incorrectly arranged. In all these cases this results in the situation that too much light is shone on the driver. This limits the driver visibility, safety and comfort of the driving.
It is an object of the invention to overcome this problem.
SUMMARY OF THE INVENTION
In one aspect is provided a system adapted to prevent a driver and/or front passenger of a vehicle being glared from oncoming light, said system comprising a vehicle, the front windscreen of which is adapted to be controllably dimmed over a selective areas thereof, and including one or more camera or sensors mounted on the vehicle adapted to provide an output signal to a controller, said controller adapted to select an area of the windscreen to be dimmed based on said camera output, and control said dimming of the front windscreen based on the selected area.
The system may include an externally-pointing camera arranged with a directivity pointing outside the vehicle in a direction to the front of the vehicle.
The system may include an internally- pointing camera arranged inside the vehicle and generally arranged so as to detect light inside the vehicle.
The system may include means to determine, from the output of said externally-pointing camera, parameters indicative of the intensity and/or distribution of oncoming light hitting the front windscreen.
The system may include means to determine, from the output of said internally-pointing camera , parameters indicative of the distribution and or intensity of light incident inside of the vehicle.
The system may include means to determine, from the output of said internally-pointing camera , parameters indicative of the distribution and or intensity of light on the drivers head or face, or the position of the driver’s and/or passenger’s head, face or eyes.
The selected areas of dimming and/or the degree of dimming in selected areas is based on one or more of these parameters.
Said windscreen may include a chromatic or translucent LCD layer; selective areas of which can be controlled to provide said selective dimming.
The degree of dimming may be is configured to be varied within sub-regions of said selective area.
The system may include radar adapted to detect the extent to which an oncoming vehicle is in position where the headlights thereof may glare the driver and/or passenger.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention is now described by way of example with reference to the accompanying drawings in which:
Figure la and lb shows views of a front windscreen used in examples;
Figure 2a, 2b and 2c shows views of a front windscreen used in examples; Figure 3 shows a vehicle equipped with a system according to examples; Figure 4 shows a plan view of a vehicle having a system according to aspects travelling along a road;
Figures 5a and b show examples of the windscreen of figures la/b before and after oncoming light is detected by systems according to the invention; Figures 6a and 6b show examples of the windscreen of figures 2a/b before and after oncoming light is detected by systems according to the invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
In one aspect a system, in an example, may comprise a vehicle having mounted thereon one or more cameras or sensors which detect the light strength, directivity and/or area of light hitting the vehicle e.g. the vehicle windscreen and/or the driver. As a result selective areas of the front windscreen are darkened or provided with reduced permittivity of light dependent on the output of the cameras or sensors.
Thus the vehicle may be equipped with a windscreen (front) with the ability to reduce the incoming light (to the driver) or darken over a particular i.e. selective area of the windscreen. The area (i.e. zone/region) is selected dependent on the output of the cameras or sensors. Thus in other words the selective area is dependent on one or more factors such as the drivers head position, the intensity of oncoming light and its distribution (all determined by cameras or sensors) . So the selected area of the windscreen is adapted to darken or pass less light through it.
Such windscreens may be formed in one example as shown in figure la which shows a windscreen 1. This windscreen is shown in cross section in figure lb, which shows the windscreen having an electrochromic layer 2 sandwiched between two glass windshield layers 3. One or more conductive layers 4 are located between the glass layers and the photochromic layer, and comprise e.g. thin wires 5 arranged in e.g. horizontal and vertical directions which divides the windscreen into sections 6 such as small rectangular or square fields/cells seen in figure la. The wires are connected to a controller (not shown). The permittivity of light through, or darkness of, the fields can be adjusted based on the applied voltage throught the respective wires. Thus particular (so selective) regions of windscreen can be darkened or adapted to let less light through; and can be controlled appropriately by applying the respective voltage with respect to the particular cells or fields.
Figures 2a and 2b shows a view and cross sectional view of an alternative design where the windscreen (windshield) 7 may be formed of an (outer) windscreen/windshield (e.g. glass) layer 8 on the outside and on the inside by a layer of translucent LCD 9. The permittivity of light/darkness through selected areas of the windscreen, and thus the brightness of incoming light from the driver’s perspective in the selected area, may be adjusted by an LCD controller (not shown). LCD control methodology is known and the skilled person would be aware of such methods and so will not be detailed here. Figure 2c shows an alternative design where an LCD layer 9 is sandwiched between two glass layers 8. Alternatively there may be two glass layers on the outside and an LCD layer on the inside.
In either case the portions/regions of the chromatic layer/translucent LCD can be activated by a control unit to selectively reduce the light passing through the selected area/region or darken it. Hereinafter the term “dimming” should be construed as this. Furthermore the degree of dimming within sub-regions (such as the cells in the figure la) of the screens may be varied.
In an example, the vehicle 10 may be equipped, as shown in figure 3, with one camera 11 which detects the driver head 13 position and /or measures ambient light in the car, and a one camera 12 which is directed outside the car to detect light sources and provide a measure of the intensity/distribution of the light directed from outside sources such as light from an oncoming direction/vehicle. Optionally or alternatively there may be one or more sensors inside the car that measure the ambient light inside instead of a camera. The vehicle 10 may be equipped with radar 14 to enable detection of objects in front of the car, and also distinguish and detect oncoming vehicles.
In the methodology, one or more of the cameras or sensors measures constantly the ambient light inside and/or outside the car. The signals of the cameras may be processed to provide data on the intensity of light and its distribution, either inside or outside the car respectively. The output of the cameras and sensors is thus fed to a control unit which determines as a result of the cam era/sensor output, which selective areas of the front windscreen are to be dimmed or reduce light passing through. The term camera is to be interpreted as a camera or other optical sensor.
Example 1:
In one example a camera arranged pointing with directivity outside the vehicle in a direction in front of the vehicle may be provided. The camera may comprise a charged coupled device (CCD) as is well known. Dependent on the intensity of the light hitting the camera and/or the distribution thereof such as the light incident on selected portions of the field of view thereof, the controller may dim a certain predetermined area of the screen.
In preferred embodiments the selected zone of the windscreen that is dimmed is varied and is also dependent on the light intensity hitting different or particular regions of the field of view. So in other words the light intensity over particular pixels of the captured image is determined and processed and dependent on this, the zone of the windscreen dimmed is selected. So in a example if an oncoming vehicle has a narrow thin spotlight beam, this is detected over a certain specific area of the camera image e.g. specific elements (and hence pixels) of a CCD for example, and the controller will recognize this and the selected area if the windscreen dimmed is made relatively small and in the affected appropriate area. In advanced embodiments, the areas dimmed by the controller can be dimmed to varying degrees.
Example 2:
In this example a camera is arranged insides the vehicle and generally arranged so as to detect light in the vehicle in particular in the region of the drivers face.
The camera may optionally or alternatively detect the relative position of the drivers head/face. The camera output will be sent to a controller and similar to Example 1, the selective area of the windscreen dimmed will be dependent on the output of the camera; the output again in examples may determine the intensity of the light hitting in certain regions in the vehicle, in particular the drivers head/or face.
Example 3:
In this example there is provided both a camera to detect light inside the vehicle and a camera pointing outside the vehicle looking toward the front, so cameras as in examples 1 and 2. Both cameras monitor the respective light intensity and distribution outside (oncoming) and inside the vehicle.
If the outside pointing camera detects increasing light or a situation where the outside light (or in one or more a particular region of the field of view) increases (e.g. above a threshold) then the inside camera (and optionally also a radar unit to detect the position of an oncoming vehicle), determines if a situation exists where the driver could be blinded. In this case e.g. then inside camera may determines the driver head position. Based on the inputs from both cameras (and optionally the radar) the controller determines which specific area of the windscreen is to be dimmed and sends corresponding control signals to the windscreen via e.g. an electrochromic/LCD control unit. Further in examples, the controller also vary the degree of dimming of specific (sub-)areas of the region of the windscreen selected for dimming.
In examples the radar may be used to detect that vehicle are oncoming in a general direction towards the vehicle equipped with the system; the radar may be adapted with the system so as to determine if an oncoming vehicle is in position that could blind the driver.
Figure 4 shows a plan view of a vehicle 10 having a system according to aspects travelling along a road in the direction of the arrow A and an oncoming vehicle 15 is travelling in the opposite direction shows by arrow B. The area where light is incident from the headlights of vehicle 15 is shown by shaded region 16. The camera field of view and radar range is shown by reference numerals 17 and 18 respectively.
Figures 5a and b and figures 6a and b shows an example of the windscreen in figures la/b and 2a/b respectively before and after oncoming light is detected by systems according to the invention. Components have the same reference numerals. A controller 19 is shown which is adapted to control the area or zones of the windscreen that are to be dimmed - these zones are shown by reference numeral 20. For the windscreen 1, the trigger bars and where the voltage is applied are shown by reference numerals 21 and 22 respectively.
It is to be noted that embodiments may also be provided which prevent glare to the front passenger in a similar way. Either the externally pointing camera or internally pointing camera may determine also the incident light hitting the front passenger’s face/head /eyes and the portion of windscreen which is dimmed is selected based on this to. Alternatively an additional camera may be provided for this purpose.
