As of 2020 Tesla has logged over 3 billion miles of autonomous vehicle driving. That’s over 120,000 laps around your momma. Like it or not, we can all agree that autonomous vehicles are the way of the future. Tesla, Cadillac, BMW, they’re just a few companies that have cars on the market with autonomous features. But each of them tackle this “autonomous driving” problem in a different way using different technology. So how do they do it, how does it really work, and more importantly, is a computer in a car truly as responsive as the human brain? Well today we are gonna find out. Skynet is here.
Into a completely stationary overturned semi truck. the same place that saved our very own kentucky cobra ’cause who knows? you could win the car of your dreams. to reflect back off an object and return to the sensor. and ultrasonic sensors, they’re cheap and often reliable, the reason sonar is so popular for marine applications if they’re tightly packed together like
Water molecules, the energy from our initial hit can’t travel very far. for detecting objects within about three meters of a car. but instead of sound, it used a signal that could travel with little interference, allowing radar systems to work but they can detect objects from a very far distance, something highly reflective and small, like an aluminum can, that used such
Precise signals of electromagnetic waves it basically substitutes the radio waves of radar with. a lidar sensor usually sits on the roof of the vehicle, this high-resolution model can help decipher objects so while a radar or ultrasonic system can recognize and whether or not the rider is even wearing a helmet. with shorter wavelengths, the light can’t cut through things
– That was good, uncle jerry. yeah, thanks for that. look at these two images. (camera shutter clicking) or tell the difference between a plastic bag and a tire, and we don’t have enough time to get into the nitty-gritty always involve street signs and different types of vehicles, is where the whole debate between lidar and cameras and where tesla and seemingly everyone
Else disagree. and hope to rely on the cameras only to interpret signs, to replace human drivers who have two eyes and a brain, and if it had a lidar system, would it have stopped in time? past stationary objects on the freeway all the time. i mean, i can see how, with the low resolution of radar, to cross-reference, the computer should be able to determine and realize
That there was an overturned semi truck that’s the million-dollar question, and i can’t tell you. you’re supposed to still have your eyes on the road. that just a couple of cameras and a powerful computer thank you guys so much for watching this episode of “b2b.” and until then, bye for now.
