Abstract
Two markers or lines are located on a side view mirror and function to inform the driver of a leading vehicle equipped with the side view mirror when it is safe to change lanes. The space between the markers is such that if the image of a trailing vehicle in a lane to which the driver of the leading vehicle wishes to move, when viewed by only one of the eyes of driver, is wholly confined within the markers, then the driver can move safely to the lane. If however, the image of a trailing vehicle is partly outside the markers, then the trailing vehicle is too close for the driver of the leading vehicle to move safely into that lane.
Description
This invention relates to side-view mirrors for motor vehicles and more particularly to a side-view mirror which informs a driver of a leading vehicle in one lane of a two or more lane highway that a trailing vehicle in an adjacent lane is sufficiently far behind to allow the driver to move safely to the adjacent lane.
One of the precautions which the driver of a motor vehicle must take when he wishes to move from one lane to a second lane in a multi-lane highway is to ensure that any vehicle in the second lane is far enough back to ensure a safe lane change. In general, a vehicle in the second lane should not be closer than about 1 '/2 to 2 vehicle lengths to the rear of the lane-changing vehicle.
One precaution that the driver of a leading vehicle can take when he wishes to change lanes is to ensure that the whole of the trailing vehicle in the lane to which the driver of the leading vehicle wishes to change is visible in his centre-mounted rear-view mirror. However this view may be obstructed by items in the storage area in front of the rear window or people in the back seat. In most trucks, there is not a centre-mounted rear-view mirror at all.
Another precaution that the driver of a leading vehicle can take is to look at the trailing vehicle in his side-view mirror. However a reliable estimate of the distance that a trailing vehicle is behind the leading vehicle is difficult at the best of times and particularly difficult when the trailing vehicle is only visible in the side-view mirror on the passenger's side of the leading vehicle. That is because the curvature of the side view mirror makes the trailing vehicle look farther away that it actually is.
I have found a way in which a driver of a leading vehicle can estimate when it is safe for him to change lanes with considerably more reliability than the means described above. In this connection, I have found that if a side-view mirror having two vertical lines is positioned in a leading vehicle such that the image of the front of a trailing vehicle is visible to the driver of the leading vehicle and if the image of the front of the trailing vehicle is entirely within the lines, it is in most cases safe for the driver to change lanes to the lane occupied by the trailing vehicle. This is so provided that the distance between the lines is permanently fixed such that the image of the front of a trailing vehicle no closer than about 1 '/2 to 2 vehicle lengths behind the leading vehicle is entirely within the lines. In addition the image of the trailing vehicle must be viewed by the driver of the leading vehicle with one eye closed or blocked.
The side-view mirror is equally effective on either side of the vehicle, whether on the driver's side or on the passenger's side.
Briefly the side-view mirror of my invention informs a driver of a leading vehicle in one lane of a two or more lane highway that a trailing vehicle in an immediately adjacent lane is sufficiently far behind the leading vehicle to allow the driver of the leading vehicle to move safely to such adjacent lane. The side-view mirror includes: (i) a mirror having means for attachment to the leading vehicle such that the image visible to the driver of the leading vehicle is of the adjacent lane, and (ii) a pair of markers on the mirror. The markers are spaced apart a predetermined

3 Like reference characters refer to like parts throughout the description of the drawings.
With reference to Figure 1, a conventional side-view mirror, indicated generally 10, consists of a conventional frame 12 within which a mirror 14 is mounted. The upper and lower edges of the mirror where they meet the upper and lower walls of the frame are marked 14a,b, respectively while the side edges of the mirror where they meet the side walls of the frame are marked 14c,d.
A conventional bracket 16 functions to interconnect the side-view mirror and the side wall of a motor vehicle (not illustrated).
Two vertical markers 20a,b appear on the mirror. The markers may be located anywhere on the face of the mirror by the method described with reference to Figure 4.
The markers may be permanently painted or etched on the mirror in which case they are immovable.
Alternatively, the markers may be movable.
With reference to Figure 2, where the markers are movable, they consist of thin rods of steel, plastic or other rigid material 26a,b having lower edges which slide in a horizontal U-shaped track formed in an upwardly opening groove in the lower segment 28 of the frame The markers may be black for daytime use but not for nighttime. The markers may be illuminated by a light within the side-view mirror or they may be illuminated by the headlights of the trailing vehicle in which case the colour of the markers should be one that is visible by reflection from the headlights of the trailing vehicle such as yellow, red or white.

4 The upper edges of the markers are each attached to a separate horizontal rack 30, 32 having teeth which engage a pinion 34. The position of the markers may be adjusted manually by causing one marker to move in one direction with resulting like movement of the other marker but in an opposite direction.
In Figure 1 the markers are continuous and unbroken from the lower edge 14b of the mirror to its upper edge 14a. By contrast, marker 40 in Figure 3 is broken into two vertical segments, an upper segment 40a which extends downward from the upper edge 42a of the mirror and a lower segment 40b which extends upward from the lower edge 42b of the mirror.
With reference to Figure 4, a side-view mirror 50 of the invention is attached to the driver's side of a leading motor vehicle 52. The vehicle is travelling in the direction of arrow 54 in the inside lane "IL" of a four lane highway. A trailing vehicle 56 is travelling behind the leading vehicle in the outside or passing lane "OL" of the highway.
The field of vision reflected by the mirror when viewed by the driver of the leading vehicle is bounded by broken lines 60a and 60b and includes the trailing vehicle and portions of the out-side lane OL on both sides of the trailing vehicle.
The markers in side-view mirror 50 function to inform the driver of the leading vehicle when the trailing vehicle is far enough behind the leading vehicle to allow the driver to safely change lanes from the inside lane IL to the outside lane OL. A safe distance is usually about 1 '/2 or 2 vehicle lengths from the back of the leading vehicle to the front of the trailing vehicle and is referred to in the explanation which follows as the "safe distance".
With reference to Figure 5, for the markers to indicate a safe distance to the driver of the leading vehicle, the positions of markers 70 on the mirror are set so that they touch or are very close to the side edges of the image 72 of the front of the trailing vehicle when the trailing vehicle is a safe distance behind the leading vehicle. In Figure 4, image 72 is bounded by the solid lines which extend out from the markers on the mirror. As is previously pointed out, the "image" is what is visible to the driver with one eye open.
The markers may be set by means of two vehicles and a tape measure. One vehicle which is to be the leading vehicle can be parked on an area of pavement at least two lanes wide of a standard multi-lane highway and three vehicle lengths long. The vehicle is parked on the right side corner of the pavement in what can be considered an inside lane while the other vehicle which is to be the trailing vehicle is located so that it is in the position that it would be if it were behind the leading vehicle in an outside lane and about 1 '/2 to 2 vehicle lengths behind the leading vehicle.
The mirror on the leading vehicle is then adjusted until it reflects an image of the trailing vehicle and portions of the outside lane on both sides of the trailing vehicle to a driver of the leading vehicle. The markers on the mirror are then adjusted until one marker is adjacent to the image of one side edge of the front of the trailing vehicle while the other marker is adjacent to the image of the other side edge of the front of the trailing vehicle. The mirror and the markers are then in a position to indicate to the driver of the leading vehicle whether it is safe to move from the inside to the outside lane of a highway.
If the driver of the leading vehicle shifts his head slightly at right angles to the line of view, the trailing vehicle can easily be centred between the two markers.
Alternatively, the driver can shift his head to bring the image of one side of the trailing vehicle exactly to the corresponding marker.
An unambiguous determination of when it is safe to change a lane depends on the driver of the vehicle equipped with the subject side view mirror covering or closing one eye because if both of his eyes are open and the driver focuses on the trailing vehicle, he will see two sets of lines on the mirror because the light from any point on the vehicle to the driver's eye via the mirror strikes a different point on the mirror depending on which eye the light comes to.
Because what one eye is blocked from seeing by a line can be seen by the other eye, the image of a line as seen defused out until it is barely visible and consequently very difficult to use in the distance measurement. It is therefore a part of this invention that only one eye be used for side view mirrors as currently installed. but either eye can be used, preferably the one that requires the least head movement to centre the image of the vehicle between the lines.
In relation to the above explanation, the vehicles used for determining the location of the markers should be of average width and have headlights which are of average distance from its side walls. Assuming that the vehicles are average in these respects, the markers should be correct-ly positioned in the side-view mirror no matter what the actual size of a particular vehicle is and what the actual distance of the headlights from its side walls is. Small differences in vehicle size and headlight position in various makes of vehicles will make little difference to the correct location of the markers. The situation however is somewhat different at night.
At that time, the glare of the headlights of oncoming traffic tends to obscure the exact location of the vehicles and for that reason the driver of the leading vehicle should ensure that the image of the headlights of a trailing vehicle is well within the markers before assuming that what he perceives to be the image of the entire front end of the trailing vehicle is in fact what appears to be within the markers.
It should also be noted that a shoulder check is always necessary before a lane change occurs to ensure that there is no vehicle forward of the field of view of a side-view mirror.
With reference to Figure 6, the subject side-view mirror 80 is attached to the front pass-enger's front door. The mirror is curved as is conventional so that the trailing vehicle 82 in the inside land is closer to the leading vehicle 84 than its image appears in the mirror. The two markers on the mirror cannot be in the same location on the mirror as the markers in the side-view mirror 86 on the driver's side of the vehicle. As a result, a separate procedure for setting the location of the markers on the passenger's side must be carried out. The procedure is the same as that described above except that the leading vehicle must be parked in a location on a paved area that will leave enough room on the passenger's side for a separate lane in which the trailing vehicle can be positioned.
It will be understood, of course, that modifications can be made in the side-view mirror of the invention without departing from the scope and purview of the invention as set out in the ap-pended claims. For example of modifications that can be made is that in the future, when video cameras might be used instead of side and rear view mirrors, two or more cameras might be conveniently located for the driver to view to the rear and to the left and right sides without turning his head. In such event, lines on the monitor which displayed the images from the cameras, might be viewed by a driver with both eyes.
In Figure 1 the markers are continuous and unbroken from the lower edge 14b of the mirror to its upper edge 14a. By contrast, marker 40 in Figure 3 is broken into two vertical segments, an upper segment 40a which extends downward from the upper edge 42a of the mirror and a lower segment 40b which extends upward from the lower edge 42b of the mirror.
With reference to Figure 4, a side-view mirror 50 of the invention is attached to the driver's side of a leading motor vehicle 52. The vehicle is travelling in the direction of arrow 54 in the inside lane "IL" of a four lane highway. A trailing vehicle 56 is travelling behind the leading vehicle in the outside or passing lane "OL" of the highway.
The field of vision reflected by the mirror when viewed by the driver of the leading vehicle is bounded by broken lines 60a and 60b and includes the trailing vehicle and portions of the out-side lane OL on both sides of the trailing vehicle.
The markers in side-view mirror 50 function to inform the driver of the leading vehicle when the trailing vehicle is far enough behind the leading vehicle to allow the driver to safely change lanes from the inside lane IL to the outside lane OL. A safe distance is usually about 1 '/2 or 2 vehicle lengths from the back of the leading vehicle to the front of the trailing vehicle and is referred to in the explanation which follows as the "safe distance".
With reference to Figure 5, for the markers to indicate a safe distance to the driver of the leading vehicle, the positions of markers 70 on the mirror are set so that they touch or are very close to the side edges of the image 72 of the front of the trailing vehicle when the trailing vehicle is a safe distance behind the leading vehicle.

The markers on the mirror are then adjusted until one marker is adjacent to the image of one side edge of the front of the trailing vehicle while the other marker is adjacent to the image of the other side edge of the front of the trailing vehicle. The mirror and the markers are then in a position to indicate to the driver of the leading vehicle whether it is safe to move from the inside to the outside lane of a highway.
If the driver of the leading vehicle shifts his head slightly at right angles to the line of view, the trailing vehicle can easily be centred between the two markers.
Alternatively, the driver can shift his head to bring the image of one side of the trailing vehicle exactly to the corresponding marker.
