At the Consumer Electronics show in Las Vegas, cruise discount celebrity Audi AG presented technologies for networking the car with its environment, with a particular focus on future piloted driving and mobile communications. Piloted driving i.e., the use of drive assistance systems that are able to assume the complete driving task for a limited period of time, if so desired by the driver will be technically feasible before the decade is out, Audi says.
In congested traffic at speeds cruise discount celebrity up to 60 km/h (37 mph), Audi's piloted driving helps the driver to steer the car within certain limits. It also accelerates and brakes the vehicle autonomously. In future, piloted driving will also be able to maneuver the vehicle autonomously into and out of parking spaces such as in tight roadside parking spaces, in garages, or even in parking garages.
Current driver assistance systems as foundation for piloted driving. Currently, Audi offers a range of integrated driver assistance systems. Adaptive cruise control (ACC) with Stop & Go serves cruise discount celebrity as the core component of these Audi driver assistance cruise discount celebrity systems. This system regulates the speed and the distance from the vehicle in front over a range of zero to 250 km/h (zero to 155 mph).
The ACC Stop & Go function employs one or two rear-mounted radar sensors depending on the configuration. The sensors cruise discount celebrity transmit radar waves in order to detect objects up to 250 meters (820 ft) ahead of the vehicle. The driver can vary the distance to the vehicle ahead and the control dynamics in multiple levels from sporty to comfortable.
"At Audi you'd be hard pushed to find an innovation that isn't related to electronics cruise discount celebrity nowadays. These enable us to implement full networking. A defining feature of the last decade was that we integrated all the functions in the car. This decade will see us network the car seamlessly with the environment, under the Audi connect banner with the driver, the Internet, the infrastructure, and with other vehicles." Ricky Hudi, Head of Electrics/Electronics cruise discount celebrity Development
In stop & go traffic cruise discount celebrity the system slows down the car to a standstill. After a brief stop, such as at a traffic light, it automatically drives off and follows the vehicle ahead; after a longer stop, the driver must tap the accelerator pedal or briefly activate the control stalk.
Audi adaptive cruise control with Stop & Go function interacts closely with other driver assistance systems; it utilizes the data from almost cruise discount celebrity 30 control units to analyze all of the vehicle's surroundings. The system uses this broad knowledge base to recognize complex scenarios and offer anticipatory support to the driver. Because cruise discount celebrity it works in conjunction with the MMI Navigation plus, it knows which route lies ahead and can use this information to control the vehicle's speed.
Virtually all the innovations that Audi brings cruise discount celebrity to automotive applications are intrinsically linked with progress in microelectronics. cruise discount celebrity Semiconductors are finding their way into virtually all areas of the vehicle and functions, right down to controlling the door locks, seat adjustment and lights. cruise discount celebrity More than 6,000 chips are now used in the large Audi models.
Audi is actively promoting progress in semiconductor technology; the PSCP (Progressive Semi Conductor Program) is a key factor in future innovations. Audi places stringent requirements on the chips, particularly regarding criteria such as long-term quality, integration and weight saving.
In the past, automakers limited themselves to commissioning a system supplier to develop a control unit, handing over a great deal of the responsibility for the associated contents. Audi has abandoned this structure in the PSCP, which was launched at the end of 2010. The system supplier remains an important contact, but Audi's engineers now also talk directly to the semiconductor manufacturers. Seven of them now have the status cruise discount celebrity of strategic partners.
Audi offers a number of versions of adaptive cruise discount celebrity cruise control for different model series, including without the Stop & Go function. The individual versions differ slightly in their mode of operation due to the different degrees of networking and configurations.
cruise discount celebrity Audi active lane assist is available cruise discount celebrity for most model lines which feature electromechanical power steering. It detects the road markings at a distance of over 50 meters (164 ft) and a scanning angle of about 40 degrees using a camera mounted in front of the rearview mirror. Software detects the lane markings and the car's actual course between them. If the vehicle approaches a line without the turn signal being activated, the system helps the driver to steer back into the lane by intervening discretely in the steering.
The driver uses the MMI to set how soon the intervention cruise discount celebrity should occur and whether it should be combined with vibration feedback in the steering wheel. If the driver opts for early intervention, the system keeps the car centered cruise discount celebrity in the lane.
The lane change assistant Audi side assist is available for various Audi models. It monitors traffic behind the vehicle and warns the driver cruise discount celebrity of critical lane changes as necessary. The system begins to operate at a speed of about 30 km/h (18.64 mph). Two radar sensors cruise discount celebrity in the rear monitor cruise discount celebrity what is happening behind the vehicle up to a distance of 70 meters (230 ft). A computer analyzes the data from these sensors.
If a vehicle is riding in the blind spot or approaching rapidly from the rear, the information stage is activated. A yellow LED indicator lights up in the housing of the driver's exterior mirror; cruise discount celebrity the driver sees it when looking into the mirror. If the driver nevertheless activates the turn signal to change lanes, the indicator becomes brighter and flashes multiple times. The optical signals are aimed at the driver. Their brightness varies according to the ambient light level and can be set individually via the MMI.
The core component of the night vision assistant is a thermal imaging camera with a 24-degree scanning angle located at the front of the vehicle. The camera, which operates in the far infrared region (FIR), registers heat radiated by objects in the field of view. A computer converts the information from the camera into black and white images and shows them on the central cruise discount celebrity instrument display.
Far infrared technology can look up to 300 meters (984 ft) ahead far beyond the range of the high beams and it is not affected by glare from headlights or similar light sources. People cruise discount celebrity tend to be conspicuously bright and thus easy to spot in the image due to the heat they give off, whereas the cooler surroundings appear dark.
The image processing software can detect persons up to a range of approximately 100 meters (328 ft) within the system constraints. In analyzing the data, it specifically seeks out characteristics of pedestrians, e.g. their contours; any person detected is highlighted in yellow on the screen. If the system predicts a hazard for example, because a person is crossing the road in front of the car the person is marked cruise discount celebrity in red and a warning tone sounds. A warning also appears in the optional head-up display.
Audi's automatic cruise discount celebrity parking systems operate by means of either ultrasound or cameras, which display images via the onboard monitor. The park assist system performs all the necessary steering movements; it can handle both parallel parking and parking perpendicular to the street. The system finds a parking space with ultrasound sensors that scan the roadside in two dimensions while driving at moderate speed. The system notifies the driver via a message in the display once the sensors have found a space which is large enough.
If the driver wishes to park in the space, he or she shifts into reverse and the park assist system takes over the steering. The driver must accelerate, shift gears, and brake. When parallel parking, the detected space is large enough if it is about 80 centimeters (2.6 ft) longer than the vehicle itself. Park assist can perform multi-point parking maneuvers and also offers support in leaving parallel parking spaces.
Another technology cruise discount celebrity from Audi is the parking system plus with surround view cameras. Four small cameras in the single-frame grille, at the rear and in the side mirror housings record the vehicle's immediate surroundings. The driver can call up a variety of views on the large onboard monitor, including a top-down virtual view. On corners or junctions with an obstructed view, the system can analyze cross-traffic otherwise invisible to the driver in front of or behind cruise discount celebrity the vehicle.
The camera-based speed limit display shows the driver the detected maximum allowable speed in the instrument cluster or head-up display. The camera mounted behind the rearview mirror cruise discount celebrity serves as the primary sensor. Within system constraints, it detects speed limit signs posted on the side of the road, as well as digital speed signs. The system compares the signs against the data from the navigation system, the maximum permissible speeds in the respective country and information from the vehicle, such as whether the wipers are on and the current time.
Audi pre sense is a safety package that is available in several Audi model series, including in the new Audi A3, in a number of different configurations. The Audi pre sense basic system evaluates information from the ESP sensors. If they signal full braking or skidding, depending on the situation, the system cruise discount celebrity activates the hazard warning lights and begins to close the windows and sunroof; it also pretensions the front seat belts. This pretensioning process, which is initiated by small electric motors, is reversible.
The safety system's configurations are: Audi pre sense front, Audi pre sense rear and Audi pre sense plus. They work closely together with the Audi adaptive cruise control with Stop & Go function and Audi side assist driver assistance systems.
Audi pre sense front monitors cruise discount celebrity traffic in front of the car for potential collision hazards. The system provides multiple levels of driver support. The first stage consists of a visual and audible sig
