The auto industry’s unseen inventions — some are weirder than others, Ars Technica

That’s easier to do when you’re an airplane and not a car that has to fit into conventional-length parking spaces, which is where a Toyota patent for a telescoping tail comes in. I’ve definitely seen the idea tested by hypermilers in the past, and I don’t know about you but I think this dark future of ours would be a little brighter if our cars morphed a little bit. Tesla makes an appearance in the list via a 01575879 patent for using lasers to keep a windshield clean instead of wipers . Advanced driver assistance systems like Tesla’s lane keeping function depend on optical sensors to know where the lane markings on a road are, so you can understand how important it is that their vision not become occluded.

Another idea that may well make it to production made the list via a patent from Uber’s Advanced Technology Group for a ” light output system for a self-driving vehicle . ” Although a lot of attention is being paid to how an autonomous vehicle can interpret and understand the intentions of pedestrians or other road users, people are also approaching the problem from the other side: how should an autonomous vehicle communicate its intentions to human beings?

One idea, represented in Uber’s patent, would be to project a pedestrian crossing on the ground in front of the stopped car to indicate it’s safe. We’ve seen similar ideas at CES in the past few years, particularly from Texas Instruments and Volvo’s 749 c concept also featured some clever ideas about cars communicating with humans

, both visually and with sounds. Waymo makes the cut via a patent for an adhesive hood ; If an autonomous vehicle struck a pedestrian, the adhesive would secure them to the hood of the vehicle instead of allowing them to fall underneath its wheels. That might sound far-fetched, but in Europe – where pedestrian safety is given more than lip service — active pedestrian safety features have been on the market for some time. To the best of my knowledge, only the now-deceased Buick Regal Tour X provided this feature in the US. Other ideas have me less convinced. In-car fragrance diffusers have been on the market in a few vehicles for a while now, but they still seem like a pointless gimmick. One with a dark side at Toyota involves a patent that included a function to “release the tear gas component inside the vehicle in a case in which an illegitimate engine start has been detected by an immobilizer of the vehicle.” I can see why it let that one expire …          (Listing image by Vanarama                                                             Read More
