Driverless Car Is Taught How To Do High-speed Turns Without Crashing
A driverless car can make high-speed turns using a machine learning algorithm that studied footage of similar manouevres. The type of artificial intelligence is called a neural network and is loosely based on how our brains work. More than 200,000 motion samples taken from test drives on an icy track near the Arctic circle to train the self-driving system not to spin out of control. It observed its motion from previous fractions of a second to adjust its steering to provide accurate motion predictions on different road surfaces. The team from Stanford University in California equipped a Volkswagen GTI with the algorithm and tested it on an oval-shaped race track. Driving as fast as physically possible and having learned from watching previous tests, the car adjusted its steering and acceleration to turn successfully. For autonomous vehicles to operate safely, they need control systems that can rapidly brake, accelerate or steer in critical situations.
This allows them to drive safely at the limits of friction - just before the tyres stop gripping the road and the car spins out.

Christian Gerdes, a professor of mechanical engineering and senior author of the paper. Professor Gerdes said his system could help in emergency situations, where sudden swerves are needed. The results were encouraging, but the researchers stress that their neural network system does not perform well in conditions outside the ones it has experienced.

Professor Gerdes said that one challenge of the neural network is a lack of insight into how it works. If you give it a set of conditions it hasn't seen before, it may extrapolate in ways that are completely wrong,' resulting in potentially dangerous steering controls, he said. The team are continuing to develop the system and vehicles that have seen thousands of times more interactions than we have, we can hopefully make them safer. The researchers are now building safety features into the system to check its decisions are reasonable. The research was published in Science Robotics.
COMPARISON: 2018 Honda Civic Type R vs. 2018 Honda Civic Type R vs. 2018 Volkswagen Golf GTI - Civic Type R is one of the most popular racing cars by fans. This car is not only fast and nimble, but also still rely on front wheel drive. With a power engine that reaches 306 horsepower makes Civic Type R difficult to find a suitable opponent. Previously we had given Civic Type R comparative versus. Ford Focus RS and now we will provide a comparison between Civic Type R with Volkswagen Golf GTI. You certainly already know the ability of each of these cars. We will give you a fair comparison and the best option we leave it to you. The choice is in your hand. You certainly already know the engine performance offered by the Civic Type R. By being the fastest in the Nurburgring circuit (breaking the previous record) makes Honda more confident. R which will provide a different driving sensation.
While the 2018 Volkswagen Golf GTI also uses the same capacity 2.0-liter TSI, 6-speed automatic DSG with Tiptronic capable of kicking more than 210 horsepower and you can control through 6-speed automatic. This car is also equipped with DCC adaptive chassis control that gives you drive mode Normal, Sport, Individual and Comfort. By choosing one of the drive modes then the perceived suspension also changed. If you look at engine performance, the Civic Type R is a bit superior to being able to provide greater power, but for comfort and driving pleasure, you are entitled to determine. If speaking exterior design, then speak the true taste that has been determined by the fans of Honda and Volkswagen. Civic Type R offers a basic body Hatchback is very sporty and modern, giving the impression of aggressive better. While Volkswagen Golf GTI also offers a unique exterior design, indicating that this car was born from the Volkswagen family, a car that has a unique and modern character. 2018 Volkswagen Golf GTI also offers exterior design that is very charming, unique and modern like a daily hatchback.
