Autonomous Vehicles| Cars of the Future Queens NYC
Driverless cars are on the horizon, but when will they be here?
Autonomous vehicles rely on a range of sensors to interact with the world around them, with the Google Car prototype coming equipped with eight.The most noticeable is the rotating roof-top LIDAR – a camera that uses an array of either 32 or 64 lasers to measure the distance between objects, building up a 3D map at a range of 200m and allowing the car to “see” hazards. The car also sports another set of “eyes”, a standard camera that points through the windscreen. This looks for nearby hazards like pedestrians, cyclists, and other motorists, as well as reading road signs and detecting traffic lights. Speaking of other motorists, bumper-mounted radar, already used in intelligent cruise control, tracks other vehicles in front of and behind the car.
Externally, the car has a rear-mounted aerial that receives geolocation information from GPS satellites, and an ultrasonic sensor on one of the rear wheels monitors the car’s movements. Internally, the car has altimeters, gyroscopes and a tachometer (a rev-counter) to give even finer measurements on the car’s position, all of which combine to give it the highly accurate data needed to operate safely.Using these arrays, the Google Car can read the road like a human, but these sensors come with their own limitations. Autonomous cars simply replace the human eye with a camera, leaving them vulnerable to extreme sunlight, weather or even defective traffic lights. In current autonomous cars, the way this selection of pixels is analyzed could be the difference between a safe journey and death. (Cars of the Future Queens NYC)
Since Google unveiled its self-driving car, it has spun off this part of the business into a separate arm under the name Waymo. The name comes from Google’s mission to find “a new way forward in mobility.” (Cars of the Future Queens NYC)
Many believe a connection between cars and traffic infrastructure is needed to combat this problem. “Car-to-car and car-to-infrastructure communication are essential for enabling autonomous driving,” says Christoph Reifenrath, senior manager in technology marketing of Harman’s infotainment division, who supply in-car tech to the likes of Audi, BMW, and Mercedes.
To become a viable solution, these systems will be required in every vehicle, including those still used by humans. It’s likely that emergency vehicles like ambulances and police cars will continue to use human drivers, so they’ll need a method of communicating with the autonomous cars around them.“You have to know where [an emergency vehicle] comes from and when it will be there, so the information is shared between this car and your car,” adds Reifenrath.
Revealed by Google earlier this month, an incident in July was caused by a human driver’s failure to stop. While correctly waiting at traffic lights, Google’s self-driving car was hit by an inattentive driver and, despite its sophisticated array of sensors, there was little it could do to avoid the incident. Luckily, the accident only resulted in whiplash for a few of the passengers, but it’s a reminder that autonomous cars are at risk when surrounded by human road users.
Autonomous cars need to understand the way pedestrians behave, while also mimicking the behavior they’d expect from a human driver. “Everyone has an appreciation of how a human being is going to react because we are all human beings,” says computer ethics commentator Ben Byford. “So if you walk out in front of a car, and presumably the car driver knows you’re there, they’re going to react in a certain way.”
However, programming also comes with a risk. By making their behavior predictable, autonomous cars could be vulnerable to manipulation by third-parties. Byford explains: “Say that the cars always react in the same way. That being the case, I could seriously injure people by walking out in front of a car on purpose, knowing that it wouldn’t be able to hit me.”
What’s more, with each car manufacturer racing to develop its own self-driving solution, the behavior of autonomous cars is becoming more and more fragmented. If this problem isn’t tackled effectively, autonomous cars of the future will be dangerously temperamental to pedestrians.“If all the major car manufacturers have a different version of this system, it’s going to make no sense whatsoever. And things can snowball into a catastrophe when people don’t understand how these things work” warns Byford. “If there were some sort of central ethic to every car applied, then at least you knew what the outcome of a certain action could be.” (Cars of the Future Queens NYC)
Autonomous cars will pack in a more prominent range of frameworks than any time in recent memory, however the expanded tech will likewise make them more powerless against programmers. In spite of the fact that it might appear an issue for the future, auto hacking is now happening. (Cars of the Future Queens NYC)
Fiat Chrysler recently had to recall 1.4 million Jeep Cherokees after it emerged they were vulnerable to hacking. Security experts Charlie Miller and Chris Valasek were able to wirelessly control functions like acceleration, windscreen, and radio, rendering the driver powerless.In an autonomous car – which relies entirely on computer systems – the effects could be devastating. It’s why laws put forward by the UK government insisted that cars have “appropriate levels of security built into them to manage any risk of unauthorized access.” (Cars of the Future Queens NYC)
Not technically hacking, but researchers recently discovered the sensors in self-driving cars can be easily confused simply by placing stickers on road signs. Worryingly, these road signs included stop signs. Autonomous cars could be tricked into ignoring stop signs, which, of course, would cause serious and potentially fatal consequences.

The Road Ahead (Cars of the Future Queens NYC)
The way things are, autonomous technology can be utilized for minimal more than stopping or path evolving. Associated auto technology is fundamental for driverless tech and, until the point when it’s here, it won’t be alright for human-worked and autonomous cars to exist together. Until the point that we overhaul our street framework, a driverless tech will depend on error prone sensor exhibits – and still be in danger from unusual, human street clients.

However, the way driverless cars react to pedestrians is an even more critical issue and one that will take extensive research and probably millions of pounds to get right. The current generation of self-driving AI is competent, but the moral judgment and behavior of human drivers will be hard to replicate.Until these problems are solved, fully autonomous cars will pose a dangerous risk to other road users. At the moment, driverless cars are only truly safe when tested and operated around other driverless cars in a controlled environment.
For the following couple of years, we’ll advantage from fractional autonomous technology, for example, path evolving frameworks, crash-evasion, and post-mischance braking. Be that as it may, completely autonomous technology is considerably further away and should be disengaged and tried in autonomous urban communities like the one developed by the University of Michigan. It turns out even the most exceedingly terrible drivers can’t be coordinated by PCs, yet. (Cars of the Future Queens NYC)
