How Do Self-Driving Cars Actually Work? (Tesla, Volvo, Google)


[Music] imagine that you’re driving in the road when all of a sudden a big SUV cuts you off there was no warning and you could have gotten into a bad accident but you were too busy reading your newsfeed to notice and rather than giving bad drivers a honk in a middle finger your automated car might just send a strongly worded letter of ones and zeros to the offending vehicle it’s crazy to think about but the future is now after years of hard work and research we’re finally on the brink of a revolutionary new form of transportation and with the hub as your GPS we will let weird distractions and funky rumors throw you off course this is how self-driving cars actually work as we get moving don’t forget to click on the subscribe button the hub will show you how of other things work too software and hardware self-driving cars are equipped with state-of-the-art software to make sure they can function as best as possible without human intervention after many years of testing the cars use top-of-the-line laser based radar systems called lidar lidar short for light detection and ranging functions in tandem with state-of-the-art GPS and inertial measurement unit sensors or IMU to pinpoint the location of the car down to a quarter of an inch an additional radar control will kick in whenever an obstacle comes within about 15 to 30 feet of the vehicle these sensors exist to keep the car running and to keep you safe but in order to be convenient and efficient the cars brain uses deep learning technology to review cameras and GPS data to predict the fastest routes to your destination with special algorithms always running between the computerized parts in and around the car’s engine the vehicle can also calculate the probability of actions to be taken by other drivers in the chance of natural occurrences as you speed down the road that said it’ll be a long time before fully autonomous cars are available for public consumption and even then the human passengers will need to stay somewhat alert in case the car has sensory or technical difficulties cost one of the biggest perks of this technology is that considering the service that offers it’s not too expensive in a standard self-driving automobile the extra sensitive global positioning system needed for these cars which would utilize internal altimeter z’ gyroscopes and tachometers for accuracy ranges between 80 to 6,000 American dollars video cameras mounted on the roof range between a hundred and twenty-five dollars to two hundred dollars radar sensors on the bumpers reach a combined total of around one hundred and fifty dollars the lidar device towering on top of the car is the most expensive at a max of eight thousand dollars and central computers which start steer and the car can average out to three times the sensor cost as calculated by Boston Consulting Group cars with the ability to put on autopilot mode would reach an extra five thousand five hundred dollars more than the asking price and $10,000 for the machinery to go entirely driverless that may seem like a good chunk of change but it’s pretty affordable when you think about how quickly a science-fiction vehicle like this could be at your neighbors fingertips safety and communication features to make sure your boss’s Robo car and your neighbor’s 1995 Corolla are able to share the road in perfect harmony government agencies like the United States National Highway Traffic Safety Administration have stepped in they’re analyzing the data to see what roadway prep is needed for self-driving cars big debut and with their new suggestions and regulations certain futuristic features may already be included on the cars in your driveway nowadays many new models include rear mounted backup cameras and as of May 1st 2018 this is a required feature by the NHTSA according to the administration they believe this development will annually save 69 additional lives forward collision avoidance is another requirement and whether you’ve noticed it or not it’s been in several different makes and models since 2003 this helpful feature applies extra pressure to the brakes when the car is approaching an obstacle at too great a speed there’s still an even bigger computerized factor in our daily commutes and that’s Lane detection some cars currently on the road have computerised autopilot on standby it kicks in when the human driver isn’t moving fast enough and the cars need to swerve into a new lane and researchers believe that the next level in road safety weather cars are fully driverless or not relies on a type of vehicle to vehicle communication this way cars regardless of where they are made would have some Universal set of signals that could be transmitted to avoid accidents and keep the commuters safe car companies but who’s involved in making all this happen well everybody once upon a time our nation was facing off against the Soviet Union in a bitter space race now Silicon Valley is teaming up with car companies in a competition to come up the most bankable self-driving car it’s what you call a race race Tesla believes they’ll have a model ready to hit the pavement by 2018 whether the Department of Transportation is ready for them or not Google Toyota Honda and Nissan think they’ll be road ready by 2020 with Google’s prototypes already having logged 1.8 million miles as of July 2016 now known as way moe Google’s self-driving car project unleashed a fleet of a hundred modified Chrysler minivans with empty driver’s seat throughout the streets of Phoenix Arizona Volvo on the other hand not only expects to have driverless cars on the market by 2020 they go so far as to say their version will be death Proof a whopping 81 percent of car accidents are caused by human error alone but the Swedish car manufacturer expects their cars to reach a full hundred percent accident survival rate thanks to their hard work manufacturing materials and steep testing regulations Volvo is known for their high safety standards but their xc90 model is a precursor to the upcoming fully driverless models and that cars key components are going to be expanded upon going forward first it has an ultra-thin steel frame that’s five times more powerful than a limit of this along with the new placement of the cars engine gives the car stronger support and a lower center of gravity to protect the passengers when paired with smart self-driving technology that can stay on the right side of the roads without lanes and steer along treacherous dirt paths Volvo might be the brand to beat taxis and trucks it takes years and years of development but businesses are expecting a huge payoff cheaper labor costs and cheaper goods for consumers something factoring into these profits however is that a truck drivers pay tends to account for a third of transportation costs what’s good for the companies may be bad for the people who need the work in Logan the most recent Wolverine movie set in 2029 robot trucks speed down freeways without tractors the only part needed is the trailer it’s more of an additional detail to communicate the time period to the audience rather than a part of the plot since the future in Logan is a pretty bleak place we can assume the filmmakers are using this as one other oddly familiar yet creepily different element of a not-too-distant time ahead like the other companies mentioned earlier Dame ler which manufactures mercedes-benz expects robot controlled big rigs to start traveling across the highway starting in 2020 with these changes in store they’ll need to be a new set of jobs for the drivers replaced by machines taxi drivers might also be replaced as companies like uber and lyft hop on board uber paired with Volvo in the Carnegie Mellon University robotics department to test vehicles do the streets of Pittsburgh in 2016 on the other side of the u.s. lyft teamed up with DRI a I in San Francisco to test its latest vehicles with human passengers and see just how the time of day and weather can mess with the cars fussy sensory equipment pros and cons the auto industry has been moving in this direction for a long time but it’s still a controversial idea of the positives the most important is the increase in road safety and the easing of drivers daily commutes since vehicles would no longer need to rely on human operation they could likely move at faster speeds avoiding traffic and simplifying parking although the general shapes of the cars we know and love might eventually change into a form that’s totally unrecognizable we’d be trading the look of cars for much more comfortable road trips imagine how boring a movie like national lampoon’s vacation would be if the family was able to take their living room shape talking car there’d be no drama but at least everyday people would be able to get from point A to point B without honking the horn or yelling at the congestion in terms of health care experts argue that the decrease in accidents would cause rising medical costs to shrink according to the US Department of Transportation every human on the road has the same value nine point two million dollars it’s always a little cold to reduce life to a number yet multiply that by the amount of people injured or worse in accidents each year and you’ll see the physical and financial toll that accidents can cost the country each year on a more positive note disabled individuals and the elderly often need to use trains or buses to travel from place to place with a car at their disposal they’d be given much more time and freedom to go where they want to go and do what they want to do plus a chain reaction of cause and effect would free up law enforcement with humans no longer a hundred percent responsible for driving speeding and DUI charges would go down then the police could spend more time focusing on matters impacting the community and two other issues would be dealt with involving the DMV and insurance companies with less drivers on the road that means less of a line at the Department of Motor Vehicles and less of a need for car insurance as the website auto dot Loan proposes car insurance may become extinct since eventually the computer will be making all the decisions perhaps the premium will be paid by the car manufacturer instead of the driver for each Pro here are some of the more shady cons to be worried about some experts warn that with the increased energy needed to power the additional devices on board increased fuel emissions could lead to more pollution outside of the smog effect and the larger price tag governments transportation departments need to come up with new regulations and licensing to make sure there’s an international standard for these cars and that doesn’t even account for the simple tactical concern that impacts all of our computers tablets and cell phones what if our car gets a virus if someone hacks into the new Ford Update could they mess with the GPS could they control the direction in which as cars traveling could they track someone’s location in real time those prospects can seem pretty scary there’s a lot we don’t know when looking ahead yet we learned from the Terminator franchise that the future is not set there’s no fate but what we make for ourselves as with all the other advances of this crazy modern social metropolitan world we’re living in will unfortunately need to wait to see whether the good outweighs the bad financial experts at Forbes say that the safety benefits of computerized cars can give six hundred and forty two billion dollars per year back to the US economy alone despite the unknowns self-driving cars just might actually work to solve our problems but we won’t know for sure until we actually see them all in action until then Volk speed ahead this was how self-driving cars actually worked since nobody’s invented self viewing YouTube content just yet roll on through the hub again soon because these videos aren’t going to watch themselves see you next time [Music]
