New cars will become smarter, safer, more efficient – and able to drive themselves.
On a sunny day in January last year, people flocked to Las Vegas to zip around the parking lot of small cars, looking more like eggs than ordinary cars. The car was electric, two wheels instead of four, with only two passengers. Because of their small size, six cars will fit the parking space. If the idea of parking such a small car makes you nervous, don’t worry: these cars can park themselves.
And pass a button on the phone back to their host.
This car is called en-v (pronounced like jealousy). It is built by general motors or general motors, and points out what the future might look like. One day, this small electric car can travel safely around people, especially in crowded cities.
Scientists and engineers are looking for new ways to make cars safer, smarter, more efficient, or use less energy. A new car may help you track your health by reminding you to take it. If it is an electric car, your car may send a text to remind you to insert it. The car will communicate with other cars, computers, mobile phones and any other device. They will help drivers save energy, pay attention to other drivers and avoid pedestrians.
This is the future of cars: safer, smarter, more energy efficient. As an added bonus, they can even drive on the highway or through the city. You can sit down and enjoy the journey.
Who needs a driver?
Google is famous for its Internet search engine, but last year it hit a highway. It sent six self-driving cars into the world. Everyone wore a device at the top, which looked like a small metal headband with a small rotating cylinder on top. People do it in there, but just give directions and make sure that the vehicle is running properly.
The cars zip around northern California, driving a bend in the Pacific Coast Highway, a narrow road that hugs the rugged California coastline. They crossed the golden gate bridge and twisted around the eight corners of San Francisco’s Lombardy street, one of the craziest streets in the world. All in all, the cars were 22,530,000 km (140,000 miles).
Companies aren’t just showing off. Google researchers think of the safety of the computer programs behind these cars to make roads safer. They say computerised cars won’t be distracted by phones or ipods. Using cameras, radar sensors and lasers, cars detect other cars and obstacles, which can help avoid collisions. Every year, more than one million people are killed and more than 50 million injured in traffic accidents around the world.
Google self-driving car project manager, engineer and computer scientists Sebastian, Aaron (Sebastian Thrun) said: “see our technical people to understand the potential of its driving more safety and reduce traffic.
Until recently, the idea of driving a car was found in science fiction. In the early 1980s, the TV knight rider gave a special speech, thought, and bullet-proof car named KITT. After the episode, the protagonist jumps into the car, gives some instructions, and then they go to fight crime and solve the mystery.
In the real world, security is the name of the game. Andrew platzer, a computer scientist at Carnegie Mellon university in Pittsburgh, points out that driverless trains have been running safely for years. Since 1987, in Detroit, automatic trains have been shuttling around the city center. In airports like Denver international airport, automatic trains take passengers to airplanes. In some ways, trains are easy: they can only move forward or back, accelerate or brake. Building automated cars is a more complex project.
“A car has a lot of decisions, not just forward and backward,” Platzer said. “You can always swing, or sway a little or more. There were other cars, and then there were pedestrians, and suddenly the traffic lights turned red and so on. ”
Driving your own car must know what other cars are doing, which means managing a lot of information. At Carnegie Mellon, Platzer and his colleagues wrote computer programs to test the safety of self-driving cars. He says self-driving cars may not be able to buy and use in the next few years, but they are approaching. Some new cars are equipped with automatic braking systems and warnings to alert drivers to dangerous situations.
Parking? Self-driving cars are also covered. Ford, BMW, Toyota, lexus, Lincoln and mercury have provided vehicles that can control the wheels to help drivers parallel parking.
One piece of driverless technology is coming, Platzer says. “We need to get some experience, build some security technology and make sure people can rely on that,” he said. “If I want to sit in the car, read newspaper, drink coffee, don’t look at road, so only I have enough trust in the system, to the reliable and safe way to deal with all the different situations in the environment.”
My car, my friend, my nurse.
Companies like GuGe are making cars smarter, safer, more independent and friendlier. Future cars may know the people who ride.
At the Massachusetts institute of technology or the Massachusetts institute of technology in Cambridge, scientists designed AIDA, which represents intelligent driving assistants. AIDA is a small white robot, sitting on the dashboard, emitting a blue light and watching the driver. The robot gives instructions and USES a camera to watch your face and identify your emotions. When you’re in a bad mood, it tries to cheer you up. AIDA also communicates with the outside world to help you choose your route to avoid traffic jams or accidents.
The ford motor company hopes cars will help people stay healthy. Onboard computers will communicate with medical devices, such as glucose monitors worn by diabetics. People with diabetes must pay attention to what they eat because their bodies struggle to maintain a balance of sugar or glucose. If the blood sugar level is too low, a person may lose direction and even faint. Soon, ford may help drivers track their body chemistry.
Other cars are being designed to respond to owners’ habits. One of the owners was Nick Pudar, who lives near Detroit. When he got home, he had to remember to charge his cell phone. He must also remember to charge his car.
“I haven’t gotten into the habit,” said Pudar, a vice President of business strategy at OnStar, which helps gm build cars and world wireless communications. Pudar drives the Chevrolet Volt, which is powered mainly by electricity rather than gasoline. If Pudar forgets to plug in his car, call him at 10 p.m. That way, the next morning he won’t have a battery.
Our lives have been powered by household appliances, computers and gadgets. If everyone plugs into a car at the same time, the network of power suppliers and operators may be overloaded and malfunctioning. There is only so much electricity at any given time.
When we flip a switch, when the light is on, we don’t think about the source of energy. ‘the power supply is like a box,’ he says. ‘it makes the rope, a little piece of string hanging on one side.’ When you use electricity, it’s like pulling a rope. The more you need, the faster you pull the rope, the harder it is to supply ropes.
“Each box has a limit, if you pull it too fast, it’s too hard, it can’t keep up,” says Pudar. “It’s a blackout.”
Later this year, onstar will test a program that will help ge electric cars. When the car is plugged in, it does not need to be recharged, and the car will use information from the power company and charge it on its own at the lowest or cheapest cost. Generally speaking, people use less electricity in the middle of the night, so this may be the best time to recharge. Electric cars need to be able to “talk” to power companies and vice versa, so they can all be smarter about energy, says Mr Pudar.
Along the ride
In 2009, Platzer climbed into a self-driving Chevy Tahoe called Boss. The car was designed by a colleague at Carnegie Mellon university. Two years ago, it won a race to drive on a city street, bringing the researchers $2 million in prize money. Mr Prazer describes himself as “the right man” and believes he is a little nervous about his machine.
“After the signal started, the Boss hit the gas and ran forward. I felt a bit like a roller coaster. Only those are safe, because they’re just tracking, “he said. “The boss didn’t track anything… . The curve was getting closer, but the Boss still had no brakes. Actually, it didn’t stop until I had a long time. It’s a rather strange feeling. ”
He trusted his colleagues, so he wasn’t too worried. Still, he says, scientists have a lot of work to do before driving safely to the streets. But he was excited about the future, just as the crowd in Las Vegas was quietly sliding in the parking lot. It’s coming. It’s fast.
“Will today’s kids have their driver’s license test first, or will the robotic car take the driving test first?” Platzer said. “I don’t know, but I’m testing a robot driver’s license. This is difficult. ”
