It’s not enough to just allow autopilots to comply with traffic regulations. Audi recently “trained†autopilots in order to get more about the human driver’s driving behavior.
The German car manufacturer started field testing of self-driving cars a few years ago. Last year, it also used an A7 (codenamed Jack) with autonomous driving function from the ERC (Electronics Research Lab). Departing, driving 566 miles (about 906km), driving to CES in Las Vegas.
In autopilot mode, the car will control the steering wheel, throttle and brakes, and can change lanes when overtaking the vehicle ahead. Jack's name is for the prayer to arrive in Las Vegas, and is taken from the "Jackpot" which represents the jackpot in the gambling terminology.
Unlike Jack arriving in Las Vegas, it completes a long-distance high-speed journey with a car speed of more than 100 kilometers per hour. The Audi A7 self-driving car tested in Shanghai, China last year was designed for urban traffic jams. Control is under 60 km.
The above tests can basically deal with urban road conditions with closed, no traffic lights and clear ground markings. Now Audi wants to take the technology of self-driving to the next level.
Recently, Audi has let Jack open the German A9 highway. The main purpose of this test in Germany was to explore V2X communication, which means that cars connect to other vehicles and road infrastructure via wireless signals and share data about the current environment.
For example, Audi uses the system settings to let Jack automatically know the information on the closed road/lane line ahead without having to detect it with its own sensors. At the same time, through the information transmitted by other vehicles to know whether there is congestion or accident in front, Jack will reduce the driving speed by himself, and it can automatically understand whether the temporary road has been opened.
But not only does Audi use the car as a test platform, but road infrastructure suppliers are also exploring new technologies, including the identification and signage of reflected radar signals, allowing autonomous vehicles to perform better beyond longer distances. Positioning.
In addition, Audi's latest navigation system allows Jack to prioritize the route that can turn on the autopilot function for the longest time, without the shortest distance or maximum fuel efficiency as the main criterion. More interestingly, Audi is trying to make Jack better coexist with the driver on the road, making it more like human driving behavior, such as when the large vehicle passes by, it will avoid leaving more space.
In addition, Jack has some little details that are unknown:
For example, when changing lanes, not only will the turn signal be turned on, but also the edge of the current lane – this is how the human driver informs the vehicle behind him of his driving intentions;
It also switches between "driving modes" between a range of driving styles. When another car wants to be merged, Jack is accelerating or braking in response to suspension, steering, transmission and engine depending on the settings.
Computerized cars mimic human driving styles are not entirely new concepts. Audi, BMW and Mercedes-Benz's map company HERE mentioned that autonomous vehicles need to make the driving behavior of the system evolve more naturally, not so blindly to avoid passenger discomfort.
This is not just a theory. By using real-time data that was originally used to reflect traffic congestion, HERE categorizes different drivers, including when they start braking, the speed at which they turn, the lane they are in, and when they begin to accelerate. Use this type of data to let autonomous cars learn how to drive.
Although it has been a while since Audi launched a fully-automobile car, the car manufacturer has already made a "radical" commitment. They confirmed not long ago that the 2018 Audi A8, which is scheduled to be launched next year, will provide autopilot on some roads.
However, this is only the beginning. Audi CEO Rupert Stadler had predicted that by 2025 we would see a fully-automobile car on the road.
