BMW shows off camera technology for improved rear vision and safety at CES 2016


Remove mirrors, insert cameras. Now if it were only possible to get rid of the selfie sticks they are attached to.

BMW i is presenting BMW i8 Mirrorless at the CES 2016 in Las Vegas. This is the first time a camera monitor system has been launched that offers BMW drivers a pioneering form of rear view with the potential to replace conventional exterior mirrors. Although different versions of driver assistance cameras are used, there has so far been no digital use of the rearview mirror which can be deployed in series vehicles. The BMW Group has also provided a demonstration with the BMW i3 Extended Rearview Mirror of how camera display systems can extend the field of vision in conjunction with existing rearview mirrors and as a result further enhance safety.

Cameras instead of rearview mirrors, a display replaces the interior mirror.
BMW i8 Mirrorless incorporates two insignificant looking cameras, accommodated in aerodynamically optimised holders, which replace the existing exterior mirrors. They are supplemented by a third camera mounted on the upper edge of the rear windscreen. All images are merged and displayed as a single image on a high-resolution display suspended in the position of the rearview mirror. The image of the traffic behind the car covers a greater viewing angle than could be observed using the interior and exterior mirrors. No adjustment of the cameras is necessary. Even relatively small and very dynamic road users like motorcyclists are recorded either by the camera or directly in vision from the side window. Dangerous blind spots have been consigned to the past.

When there are hazards: warning alerts in the display.
The display is around 300 millimetres wide and 75 millimetres high. This is rather bigger than the holder of a standard modern interior mirror today but it has a more appealing look. The casing is rounded at the side and this conveys a natural panoramic perception of the traffic behind the car. A further special feature of this system is that it evaluates the camera images and responds situatively to imminent hazards. If, for example, drivers signal with their indicator that they are about to overtake, although a car is coming up behind which is travelling much faster, a striking yellow warning icon immediately flashes on the display and this increases in size as the hazard intensifies. Or if a driver is about to turn right at traffic lights, the system recognises that the vehicle is turning a corner by the indicators flashing or the steering wheel being turned sharply, and the image in the display automatically swivels further to the right and extends the area being displayed. If a cycle rider approaches from the rear, a warning signal is illuminated in the display as well.


Passengers also benefit from the mirrorless system.
However, the mirrorless camera display system also offers additional advantages. The cameras replacing the exterior mirrors are smaller than the existing wing mirrors and permit a more open view to the front and side of the car. The display prevents the driver from being subject to direct glare and the contrast can be optimally adjusted to suit the light conditions. Overlaid trajectory lines also provide support for drivers when they are parking. Moreover, passengers can similarly use the new mirrorless system. Like the driver, they can always see the traffic in the display, and when they are getting out they can see whether pedestrians or cyclists are in danger before they open the door.

Optimised aeroacoustics reduce wind noise.
The cameras mounted at the sides of the BMW i8 Mirrorless record the traffic travelling behind the car and they are positioned in wing-like holders at the same height as conventional exterior mirrors. The holders are optimised aerodynamically and aeroacoustically so BMW i8 Mirrorless not only has a cw value like a BMW i8 without exterior mirrors – with the equivalent positive effects on consumption – but also generates a similarly low amount of wind noise. Moreover, the holders channel rainwater round the side windows. The lens of the two side cameras is made of Gorilla Glass Type 2, a thin and robust glass which is frequently used for displays of electronic devices with touchscreens and features particularly high scratch resistance and braking strength. The protective glass on the camera lens is provided with a dirt- repellent coating, is heatable and does not require servicing so as to be able to always provide a reliably high image quality under all traffic conditions, during any weather and in all lighting conditions. The holders are also designed so that spray water is conducted around the lens. The absence of an exterior mirror reduces the overall width of the BMW i8 Mirrorless to 1,942 millimetres because the camera holders finish at the width of the rear wings of the BMW i8.


BMW i3 Extended Rearview Mirror: improved rear view.
Camera display systems can also be used in conjunction with conventional exterior mirrors to improve the view behind the car. This is demonstrated by the BMW i3 Extended Rearview Mirror. The interior mirror is particularly important in this vehicle. It overlays the usual mirror view with very precise images from a camera in the antenna foot on the roof of the vehicle. This mix of mirror and camera view significantly extends the driver’s field of vision to the rear. At the same time, the reference to the surroundings is retained and it is easier to assess the extent to which other vehicles are still far away or how quickly they are approaching.

Mirrorless concept car

I like this a lot. Unfortunately, nobody in the United States will have one anytime soon. Just as in the case of laser headlights, regulations do not allow it. NHTSA requires rear view mirrors and the language does not make room for substitutes, even superior ones. So it will be a while before we'll see this. Regulations have to catch up tob the technology.

At least the FDA isn't involved like they are with laser lights! FWIW, they are the ones that have put the major hurdle in laser lights...they say nobody but the military and medical need lasers that powerful; regardless that the lasers excite phosphors, and don't directly light the road.

Mirrorless car and FDA

It is entirely appropriate for the FDA to be involved. An accident can uncover the lasers and someone can be seriously injured. BMW has installed a power cutoff to deal with that, but it is appropriate and desirable that the FDA, which regulates lasers, vet that system before it hits the road. I think we can complain that the FDA takes too long to get its work done, but part of that is budget for the agency, and part of that is agency culture. The Volkswagen/Audi/Porsche debacle teaches us that we want effective regulation - but with a process that keeps up a little better with technology.
