Volkswagen is testing anti-vomit technology for autonomous cars

VW’s solution is better than a barf bag, but testing continues on the perfect solution to a messy problem.

One-third of all people are highly susceptible to motion sickness, according to the National Institutes of Health.

It tends to get worse when that susceptible person is a passenger instead of a driver, which will be the case more often as self-driving cars and semi-autonomous driving features enter the mainstream.

Volkswagen is testing solutions to carsickness in self-driving cars that involve such features as red and green LED lights and movable seats.

Forget the technical and safety challenges facing self-driving cars’ march toward the mainstream: good old-fashioned carsickness is coming up as a worthy consideration for automakers designing autonomous vehicles. Volkswagen has announced that it has set scientists in Wolfsburg, Germany, on the task of studying motion sickness in autonomous cars and developing anti-puke solutions (our term, not VW’s).

One set of Volkswagen’s tests uses large strips of LEDs inside a car that glow red or green in concert with the car’s slowing and acceleration to help occupants gain a sense of anticipation for a self-driving car’s moves. (Carsickness often is brought on by passengers’ not knowing or being able to predict the driver’s next moves, hence the proposed feedback loop’s value.) To combat illness relating to a mismatch in an occupant’s perception of a vehicle’s movement and the movement itself, another common source of carsickness, VW is playing around with the idea of movable seats. So far, the science fair going on in Wolfsburg hasn’t produced concrete solutions along the lines of, say, Citroën’s Willy Wonka–style anti-emetic glasses.

To evaluate these ideas, VW is running tests that place subjects in a self-driving car, rigs them up with skin-temperature and heart-rate sensors as shown above (as well as cameras that evaluate skin tone), and makes them ride through 20 minutes of stop-and-go movement behind a lead car. To mimic a future in which autonomous cars are so trustworthy that you could watch a movie while in command of one, the test also involves a tablet display mounted to the dashboard that plays a video of fish swimming (to negate emotional impact on the sensor array from a comedy or drama film). Unsurprisingly, without any countermeasures in place, the occupants often experience illness.

It might not seem newsworthy to announce that Volkswagen is considering ways to keep you from barfing in a self-driving car, rather than a real, production-ready solution to keep you from barfing in a self-driving car, but then again autonomous cars aren’t yet commercially available. When—or if—they do get there in this lifetime, you’ll likely appreciate the work Volkswagen and other automakers are putting into carsickness solutions.
