32 AUDI Driving System of all aspects of the dynamic driving task with the expecta- tion that the human driver will respond appropriately to a request to intervene." So the task of the driver, when the system is activated, is not to constantly monitor what's occurring, but to be able to take control of the vehicle when required. The Audi system works on divided highways (when there is a physical barrier between the two directions of travel) and at speeds of 37.3 mph (60 kph). The real purpose of the AI traffic jam pilot is simply to provide relief when, as the name implies, the car is in a traffic jam. But what, as this is about powertrain, is an autonomous driving discussion doing here? Simple. The A8 is arrayed with a suite of sensors. There are a laser scanner, long-range radar and camera in the front. Then there are 21 other sensors, including four mid-range radars at the corners, four surround cameras, 12 ultrasound sensors, and an infrared camera. All of these sensors are actively looking for lane markings, other vehicles and objects. But there is also an intelligent power- train management system. This system makes use of information including sensor input as well as navigational route data. The powertrain management system is then able to calculate such things as whether to put the car into coasting mode or to use regenerative braking to recover energy (up to 12 kW). In addition to which, the system can use the BAS system to slow the A8 should a vehicle be traveling in front of the car. That leads to additional energy gain, which Audi calculates is on the order of 0.2 U.S. gallons per 62.1 miles (or 0.7 liters per 100 km). Perhaps not much, but every drop helps. REALLY ELECTRIC While the new A8 is the first of many electrified vehicles that will be coming from Audi during the next several months, mild hybrids as well as fully The Audi A8 under the skin. Although there is a 48-volt system serving as the basis of the hybrid, there is a 12-volt system in the car, as well.
