In the future, it might be possible to drive a washboard dirt road and barely feel the bumps. Some cars already have some of this functionality. In fact, you can have a suspension that responds perfectly to road bumps, potholes and other problems because it knows they are there, either from the map or from the laser scanner which measured the geometry of the road. Softer suspensionĪt a far simpler level than a banking passenger compartment, a robocar doesn't need the tight, driver-oriented suspension that lets you feel the road. The ability to see that while staring at your device could help. I don't think people will want those for working, but you could but in screens to make parts of the body seemingly transparent, or simply provide an artificial horizon like these glasses. I've seen concept cars with screens all over the doors. This might be able to train the brain to get a different channel of information (through the inner and outer ear rather than the middle.) More likely, it could provide an unconscious signal that "it's time to look up now" so people pause in their reading before the turn. In spite of this, the noise would make subtle changes in tone when there are upcoming or current accelerations. I would like to experiment with making a quiet background noise - perhaps so quiet you are not consciously aware of it. It can also know about upcoming bumps in the road and some of the need for braking. Provide audible cuesĪgain, the car knows how it plans to turn. And robocars will be great at roundabouts, always judging their merge perfect and thus rarely slowing down much except when they are fairly busy. Driving at high speed through roundabout after roundabout could make anybody sick. This would definitely be valuable in places where roundabouts are common, like much of Europe. You would need to make sure nobody could get their hand under the seat. Moving the whole passenger cabin is hard, it would be better if you just had to tilt the seat. In fact, if you want a narrow stance vehicle for single people, there is no choice but to lean in order to maintain stability. This might combine with a vehicle that has independent wheel suspension so the whole vehicle is able to "lean" in turns, as a motorcycle does. Done perfectly, a ball placed on the seat would not roll during any of these turns.īecause a robocar knows the geometry of all planned turns perfectly, it could make this adjustment. In other words, they would never feel the car tilt, accelerate or brake, they would only feel themselves get lighter or heavier, like you do in an elevator. Done right, you could tilt the passenger so that the "net force" is always only up or down from their perspective. This would allow the vehicle to tilt the passenger left or right, or forward or backward, depending on how much the car is turning or accelerating.

Here are some other thoughts I have had over the years on addressing this problem: Bank the car and the seatsĪ robocar might be made with a passenger compartment - or just a passenger seat - mounted on hydraulic actuators like a simulator pod. While they have to make them look better, the idea is an interesting one, and those who really suffer from this may not mind looking uncool, especially in a solo car. Similar glasses have been used at sea for some time. These make an artificial horizon in two dimensions, no matter where you are looking.
They gave people some very geeky looking glasses with circular liquid "levels" both in front, and to the sides. I've been pondering this for a while, and recently came upon an interesting effort from a team at French automaker Citroën. Of course it happens on ships due to the waves and rarely on trains which make few turns and don't bounce much. Looking out at the horizon puts your eyes and balance in agreement, and makes it better, but on a winding road, even that can be not enough. Looking down at your book, your eyes see it and the interior of the car not moving, but your motion sensors remind you that you really are. Motion sickness generally results when your eyes and inner ear (balance) tell you different things.

Drivers usually don't feel this much, but in the robocar world, everybody's a passenger. Not everybody gets this, but it's enough to be a big issue for the robocar world. For a lot of people, being a passenger in a car can easily lead to motion sickness, particularly if they try to do something like looking down to read a book or stare at a phone.
