MOBILITY FOR MEGACITIES: AUDI AI:ME
>> Vision of an autonomous city car of the future
>> Small traffic area, maximum spatial comfort
>> High-tech refuge during rush hour
At Auto Shanghai, Audi introduced a visionary mobility concept for the megacities of the future: The showcar, known as the Audi AI:ME, offers compact dimensions, a spacious, futuristic interior, and the ability to drive autonomously at level 4. This allows the occupants to do what they like with their time on board. The Audi AI:ME offers a broad range of high-tech features for communication, entertainment, or simply relaxation.
The body line of the Audi AI:ME demonstrates how emotion and spatial economy can form a perfect synthesis in an electrically driven compact car. There is a reason that the name AI:ME emphasizes the relation to the Audi AIcon, the study of automated long-distance operation introduced in 2017. The affinity of the body line and the concept of these two cars will become evident in Shanghai, as the AIcon will flank the world premiere on the stage of the Audi booth at Auto Shanghai .
Audi AI:On our way to automated mobility
Audi AI:ME and Audi AIcon: two concept cars whose very names refer to the new, two-letter abbreviation under which Audi is bundling an entire cluster of innovative mobility technologies. Audi AI is the cipher for a variety of electronic systems that relieve strain on drivers and simultaneously offer them new possibilities to use the time spent in the car. To this end, Audi AI also uses strategies and technologies from the field of artificial intelligence and machine learning. Audi AI also combines vehicle intelligence, which makes automated driving possible in the first place, and interaction intelligence, which turns the vehicle into the occupants’ partner. The name of the Audi AI:ME thus already makes the connection between AI and the users themselves.Audi AI systems are capable of learning and thinking, while also being proactive and personal. Thanks to Audi AI, models bearing the four rings will be both intelligent and empathetic in the future. They will be able to continually interact with their surroundings and passengers, and thus adapt themselves in a better way than ever before to the requirements of those on board.
Automated driving at level 4: Relax while gliding through the city
What is long established in rail transportation and even aviation is at the threshold of a breakthrough in automotive transportation—automated driving. The Audi AI:ME is designed for use in the city and for driving at what is known as level 4. This is the second-highest level on a standardized international scale for increasing automation. Although systems with level 4 do not require any assistance on the part of the driver, their function is limited to a specific area—such as highways or a specially equipped area in inner cities. In these places, the driver can completely transfer the task of driving to the system. The driver needs to resume the task only when the car leaves the area defined for fully automated driving. By contrast to the Audi AIcon, a vehicle with level-5 function that is always fully autonomous, the Audi AI:ME is therefore equipped with the traditional steering wheel and pedalry control elements in addition.
This means that the car, as well as the remaining road users, will drive automatically in a defined traffic area equipped with the corresponding infrastructure in the future. Self-regulating and self-controlling flows of traffic allow the vehicle to glide along calmly, avoiding heavy longitudinal or lateral acceleration. This is an important requirement for the occupants of the car to be able to detach themselves mentally from the traffic around them.
Luxurious refuge and high-tech control center: the interior
Audi AI fundamentally changes how automobiles are used and significantly enhances the time spent on board. The car is increasingly becoming a “third living space” alongside our homes and workplaces. It is thus only consistent that the Audi designers did not subordinate the interior of the Audi AI:ME to the shape of the body. On the contrary. They prioritized the interior and made it the core of the whole vehicle. The focus here is less on the traditional connection between driver and vehicle—steering wheel, instruments, pedals—and more on the time spent in the automated vehicle. This is why these control elements are retracted with an elegant and sophisticated choreography and are then almost fully concealed by a stowage compartment with a surface made of open-pore walnut wood.
The vehicle and as the communication and interaction systems are operated by means of eye tracking, voice input, and touch-sensitive fields in the door rail. They are positioned perfectly in terms of ergonomics and are normally integrated into the surface, making them invisible. The lighting is activated only when approached, and guides the user’s gaze to the functional surfaces.
There is a multifunctional, three-dimensional OLED monitor that runs below and along the entire length of the windshield and is used primarily in dialogue with eye-tracking control. Terminologically coded function menus, for example for navigation or infotainment, can be activated with the eye and then open up further levels that move from the background into the sharp view mode on the 3D monitor.
There are VR goggles on board for the visual output of the infotainment system. They turn Internet use, watching movies, or even interactive gaming into a fascinating experience for the passengers. Audi demonstrated the possibilities that await us in the future with the Holoride system at the CES 2019 in Las Vegas. Here, the vehicle’s own movement is detected by a sensor system and then integrated interactively into the visual course of a game. Passengers feel like they are literally in the midst of the action.
The occupants experience the interior of the Audi AI:ME not simply as a means of transport, but as a luxurious atmosphere with numerous high-tech features. It also literally acts as a filter that keeps out the omnipresent traffic all around. The high-quality audio system is coupled with noise compensation that can completely suppress the outside noise level by means of active noise control. This allows occupants to enjoy meditative silence or listen to music in concert-hall quality in the Audi AI:ME.
See and be seen—the lighting
With the self-driving cars of the future, headlights will have a part-time job at best because the driver will be concerned with other things most of the time and will rarely need the road to be brightly illuminated. It is another function of the lighting that takes on a more important role here: communicating with other road users. The Audi AIcon already demonstrated how digital matrix luminous surfaces can use moving graphics to output clearly understandable signals relating to the driving condition and, of course, also to mark the vehicle itself.
The Audi AI:ME takes this approach one step further: As road users come even closer in the city, the traditional positions of the front and rear lights are often not visible. Because of this, Audi lighting designers integrated LED elements in the body in an unusually high position above the wheel wells, where they are visible from all angles. This 360-degree communication is an important additional safety feature for pedestrians or cyclists.
Like in the AIcon, the LED units at the front and the micro matrix projectors can use easily identifiable symbols to signal to pedestrians when the AI:ME is letting them cross the road, for example. The graphics can be projected onto the road or a wall. This function is also used to illuminate the door area to ensure that occupants can enter or exit the vehicle safely and also to mark the vehicle for other road users. The matrix projectors can also provide additional safety to other road users with weaker lighting by automatically illuminating their surroundings.
The Audi AI:ME features a further innovation: It can interpret signals from other vehicles and use its own lighting technology to amplify them if this benefits the surroundings. Example: A vehicle driving in front indicates danger with faint hazard warning flashers. The AI:ME can detect this signal and amplify it with projections and the LED units on the body so that it is clearly visible to all road users.
As a level 4 vehicle, the Audi AI:ME is equipped with bright LED headlights and perfectly visible brake and tail lights for all those situations in which drivers take the wheel themselves. When driving actively, being able to see is just as important by night as it is by day in the future, too.
Mobile for hours: the drive architecture
Audi took a targeted approach to tailoring the specifications of the AI:ME to the scope of use of a city car. This means that extreme acceleration values and top highway speeds are just as obsolete as high cornering speeds and ranges that are suitable for driving long distances. An automobile like the AI:ME will drive predominantly in the speed range between 20 and 70 km/h (12.4 and 43.5 mph) and will often have to remain mobile for hours at a time without charging. However, long ranges in terms of kilometers are less relevant than the ability to make good use of the operating time.
The engineers therefore drew on a comparatively simple, yet light, basic configuration. A battery unit with a storage capacity of 65 kilowatt hours is sufficient for meeting these requirements. A permanently excited synchronous motor that can mobilize 125 kW (170 metric hp) if necessary operates in the area of the rear axle of the AI:ME. A fraction of this is usually sufficient for keeping up with the flow of city traffic. Thanks to brake energy recuperation and its comparatively low weight, the Audi AI:ME exhibits extremely low energy consumption even in city traffic.
The axles and other components of the suspension are found in the portfolio of compact sister models of the Audi portfolio. The tried and tested combination of adaptive dampers and small unsprung masses ensures good ride comfort in the city. The body is made of a light-weight multi-material compound consisting of high-tech steel, aluminum, and plastic components, particularly in the attachments.
Audi on request: innovative offer concepts
After the Audi AIcon, which debuted at the International Motor Show in 2017, and the radical Audi PB 18 sports car, which was introduced in the summer of 2018, the Audi AI:ME is now the brand’s third vision vehicle to present an offer for use in clearly defined areas (“use cases”). While the Audi AIcon offers the qualities of a business jet for long-distance drives, the PB 18 is a vehicle for the occasional trip to the race track. The Audi AI:ME is the perfect companion for use in conurbations. A fourth vision vehicle will complete the concept quartet at the International Motor Show in September.
The top priority given in the specifications for these test mules is not to design an all-rounder for the versatile and long-term spectrum of use of a heterogeneous clientele. These are highly specialized premium automobiles that can be ordered as needed and with extensive possibilities for individualization as part of an on-demand offer. This approach is based on the requirement profile of many customers, especially in urban areas, which is undergoing a transition. Automobiles are to be available and ready for use upon request and should ideally be custom tailored, but they need not pass into permanent personal ownership. However, premium customers still demand that they can order their automobiles with as many individual features as possible—and, of course, with the same high quality they are used to and expect—from the Audi.
Customers who book a vehicle will then not only get their desired vehicle, but can also have it configured to suit their personal preferences as far as possible. The color, interiors, and technical options can be pre-configured online with the app or via the driver details stored in the “myAudi” system. Even drivers’ preferred interior temperature, the perfect ergonomical seat adjustment, and their personal music library are already activated when they get into the car.
This offer is accessible and easy to use via an app that connects the vehicle order, personal preferences of the user, and numerous options that can be used while driving. Users make use of this app to order their Audi AI:ME and can preorder the car with two or more seats, and even a child’s seat, as required. They will find the AI:ME at the requested time and in the agreed-upon place and can simply park it somewhere after using it. In zones with the appropriate equipment, the vehicle can even travel between the depot and the customer’s address without a driver.
The app, which is operated via a smartphone and in the car itself, also serves as an assistant and intermediary for many other services. For example, it can be used for spontaneous communication with friends via the Internet or social media. Users can take selfies on board and share them in social networks. They can access the entire Internet for the purposes of entertainment, research, and service. Users can order food on the way and make a quick, automated stop at a restaurant to have it delivered to the car, and then enjoy their meal in the vehicle on their way home.
The connection between the user’s home network and the Audi AI:ME even allows users to continue watching a movie using the VR goggles in the car, picking up where they left off at home. On their way home from work, they can close their eyes, enjoy the silence on board, and relax.
The Audi AI:ME becomes a fixed point in its user’s personal digital biotope. The tedious daily journey from A to B turns into an enjoyable ride with free time. After they have arrived at their destination, the users can get out of the car, relaxed and in good spirits, and do not even have to look for a parking spot or charging station. The Audi AI:ME will find its own way back to the depot.
“Audi on demand” is available in metropolises on several continents and is already the perfect example of the future expansion of Audi’s offer into a global mobility service provider. With the simultaneous expansion and specialization of the vehicle fleet, this program will become even more attractive to customers with high demands in the future. The premium vehicle offer itself and the digital integration of the automobile and living environment will give the Audi brand a head start in this segment, too: Vorsprung durch Technik.
