Engineers at Ford have been working on how to keep sensors on automated vehicles clear of debris like bugs

Developing a vehicle that can drive itself takes a lot more than just some complex artificial intelligence, state of the art graphics chips and expensive sensors. At least it does if you want the vehicle to drive itself around safely and reliably in all sorts of conditions. Just as we mere humans need to be able to see through the windows in order to navigate our environment, cameras, radar and lidar need an unobstructed view of the world.

Krishnan and his team incorporated something like this in to the structure that holds the sensors on the roof of the automated vehicles being tested by Ford and Argo AI. Air is channeled from the front of the so-called “tiara” and across in front of each camera. This curtain of high speed air prevents most of the bugs from impacting the sensor. Still, those air curtains aren’t impermeable. When debris does hit the sensor, software in the AV system can detect if it has become obscured.

Will Self-Driving Cars Really Only Last Four Years?A recent claim by a major automaker suggests that true self-driving cars might only last 4 years at a time, consider the ramifications if true. Did anyone even say this? Article appears to assume that there will be as many AVs as current cars on the road. MaaS results in fewer cars on the road, but they’ll be driven more. Assuming nothing else changes, the number of cars scrapped per year will be much the same.
