An intelligent combination of different technologies enhances the safety, comfort and efficiency of the new Audi A5 Coupé. At the same time, Audi is also taking the next step toward piloted driving. The broad choice of innovative driver assistance systems sets new standards in the segment. Compared with the previous model, nearly all of the systems are either completely new or have been extensively updated. Some of the solutions are standard features, whereas the options can be chosen individually or are available in the packages “Parking,” “City” and “Tour.”
Greater safety: Audi pre sense
The A5 Coupé comes standard with the safety system Audi pre sense city. At speeds of up to 85 km/h (52.8 mph), the system scans the road for other vehicles and pedestrians using a windshield-mounted front camera with a range of over 100 meters (328.1 ft). If it detects an impending collision, the driver receives a series of warnings, and if necessary the car initiates maximum braking. At speeds up to 40 km/h (24.9 mph) accidents can be avoided completely within the system limits. At higher speeds (up to 85 km/h (52.8 mph)), warnings and brake intervention reduce the impact velocity.
The optional Audi pre sense basic uses information from a variety of different vehicle systems. Once it detects an unstable driving condition, it initiates preventive measures to protect the occupants. The front seat belts are tightened electrically, and the windows and the sunroof close. The hazard flashers are also activated. If a collision cannot be avoided and an accident is detected on the basis of contact, the multicollision brake assist system supports the driver with controlled application of the brakes. This can help to prevent the car from skidding, which in turn prevents additional collisions.
Fewer traffic tickets
thanks to the speed limiter
Another standard feature in the new Audi A5 Coupé is attention assist. A component of the driver information system, it analyzes driver behavior and issues a warning when it detects that the driver is becoming inattentive.
The adjustable speed limiter, a standard feature, can be set to a particular speed ranging from 30 to 250 km/h (18.6 to 155.3 mph) – a very helpful tool for maintaining speed within city limits, in construction sites, and so on.
Adaptive cruise control (ACC) Stop&Go
including traffic jam assist
A highlight among the optional systems is the adaptive cruise control (ACC) Stop&Go including traffic jam assist. It relieves the driver and is a major plus with respect to convenience and safety. The ACC maintains a specified distance between the new Audi A5 Coupé and the car ahead; the driver can choose one of five distances and use Audi drive select to adjust the rate of acceleration and control dynamics.
The system, which relies primarily on the signals from the two front radar sensors and the camera, interacts with the S tronic and the tiptronic to cover the full range of speeds from 0 to 250 km/h (155.3 mph); with manual transmissions, it starts at 30 km/h (18.6 mph).
The Stop&Go function of the ACC (in conjunction with automatic transmissions) brakes the new A5 Coupé* to a full stop and lets it resume driving again at the driver’s request. When the system is deactivated, the distance display shows the distance to the car ahead and warns drivers when they are tailgating. Its operating range is at speeds of 60 km/h (37.3 mph) and above.
In combination with automatic transmission, an extension of the ACC called traffic jam assist can take over steering at speeds of up to 65 km/h (40.4 mph) on well-developed roads when traffic is congested. The system uses the radar and ultrasound sensors as well as the front camera, guiding the car by gently adjusting the steering and following the traffic ahead within system limits. The traffic jam assist orients itself to the lane markings and the other vehicles on the road.
When traffic jam assist reaches its system limits – such as when the traffic thins out or there is a sharp curve ahead – the driver has to take over again. If the driver does not, the system warns the driver in several stages. As a final measure, it safely and autonomously brings the Audi A5 Coupé to a full stop.
ACC Stop&Go including traffic jam assist means that the Audi pre sense front safety system is also on board. It can prevent rear collisions or help minimize their consequences. In dangerous situations, the system prompts the driver to apply the brakes according to a complex warning concept – with visual and acoustic signals as well as a sharp tap on the brakes. If the driver does not respond, the car first starts to brake while simultaneously closing the windows and the sunroof as well as activating the hazard flashers. The A5 Coupé is the only car in its class to perform maximum breaking thereafter. The system also tightens the seat belts at this point.
the predictive efficiency assistant
Also included in the Tour assistance package is the predictive efficiency assistant. Unique in its class, the system works in close conjunction with the Audi adaptive cruise control (ACC), the Audi navigation system and the camera-based recognition of traffic signs. When ACC is active, the system predictively and automatically adjusts the preselected speed to conditions – the route topography, speed limits and the traffic ahead.
Regardless of whether route guidance is active or not, the predictive efficiency assistant uses the route data to alert the driver about situations that call for lower speeds. The system recognizes curves, traffic circles, intersections, gradients, city limits and speed limit signs – in many cases long before the driver sees them. A corresponding warning appears in the instrument cluster and/or the Audi virtual cockpit and head-up display. If the assistant screen is active, detailed graphics can be seen.
If the driver wishes, the system can control the freewheeling of the automatic transmission under defined parameters. This form of coasting is only activated if it can last for at least five seconds. When it ends, the car automatically accelerates to the speed the driver has selected provided the ACC is activated. The predictive efficiency assistant can reduce fuel consumption on country roads by up to 10 percent.
in the Tour assist package
From a speed of 65 km/h (40.4 mph), Audi active lane assist – part of the Tour assist package and also available separately – helps drivers stay in their lanes. It receives its signals primarily from the front camera, which detects lane markings. If the new Audi A5 Coupé approaches a marking without the turn signal being activated, the system makes a gentle adjustment to the electromechanical power steering to bring the car back into its lane.
Using the Audi MMI system, drivers can decide whether this support should be active at all times or only take place before the lane marking is crossed. If the driver opts for early intervention, the system guides the car to the center of the lane. There is also the optional setting of making the steering wheel vibrate.
The collision avoidance assist is yet another high-end feature in the Tour assistance package. It activates when an obstacle must be avoided to prevent an accident. Within fractions of a second, it uses data from the front camera, the ACC and radar sensors to calculate the distance of the car ahead as well as its width and degree of offset. Its first warning is a tap on the brakes to alert drivers to the potential danger. As soon as the driver starts steering, the system offers support with the necessary lane changes with controlled interventions in the power steering.
Another Audi innovation is turn assist, which at speeds between 2 and 10 km/h (1.2 – 6.2 mph) monitors oncoming traffic when turning left. In dangerous situations, it brings the car to a complete stop. The system becomes active in the background as soon as the driver turns on the left turn signal.
Camera-based recognition of traffic signs rounds out the Tour assist package. This is also available outside the Tour assist package in combination with one of the two Audi navigation systems and the color DIS. It detects numerous traffic signs, including digital displays and supplemental signs, and presents them to the driver as graphics in the head-up display and instrument cluster. In addition, the driver can opt for a visual warning if the sign-based speed limit is exceeded.
City assist package
The City assist package includes the lane-changing feature Audi side assist, which is also available separately. At speeds of 15 km/h (9.3 mph) and above, it uses the two rear radar sensors with a scanning range of some 70 meters (229.7 ft) to support drivers when changing lanes. If a vehicle approaches rapidly or is located in the blind spot, a warning LED in the housing of the respective exterior mirror lights up. If the driver activates the turn signal anyway, the LED flashes brightly several times in succession.
Audi pre sense rear warns about potential collisions from behind and takes preventive measures, such as activating Audi pre sense basic. The hazard lights also flash rapidly as a warning to traffic behind the car. It remains active in the background at every speed even if the Audi side assist is turned off, unless a trailer is in use.
The new cross traffic assist rear is enabled when the parking system is activated. When this occurs, drivers who are slowly driving backwards, such as when leaving a parking spot at right angles to the road, are warned about approaching vehicles in critical range. There are different levels of warnings: visual, acoustic and a short jolt of the brakes. The back radar sensors provide the necessary data.
The exit warning helps the new Audi A5 Coupé move more safely through urban traffic. It is activated when the car comes to a stop. If other vehicles are approaching from behind, it warns occupants as they open the doors. The system warns drivers by means of LED light guides above the inside door handles (contour lighting). In situations that are assessed as dangerous, special high-output red LEDs blink and light up. The exit warning stays on for approximately three minutes after the ignition is turned off.
Additional systems round out the City assist package: the reversing camera as well as the acoustic and visual parking system plus. They activate automatically when an obstacle is detected while maneuvering. Both solutions are also available separately.
A fully equipped new Audi A5 Coupé has some 90 control units on board, all of which exchange data with each other. This high degree of networking, especially among the driver assistance systems, would not be possible without a brand new approach to the car’s electronic architecture.
The new FlexRay bus system connects multiple control units with each other and guarantees extremely fast and reliable data transfer. The most important components are the engine, the automatic transmission, the central chassis control unit, electronic stabilization control (ESC), the power steering control unit, adaptive cruise control Stop&Go including traffic jam assist, the image processing control unit and the safety computer, which controls the safety systems.
There are other data networks in addition to the FlexRay bus. CAN (controller area network) buses are the standard networking technology. CAN is used for such things as the air conditioning, convenience electronics and assistance systems (Audi side assist). Furthermore, CAN is used for communication between the infotainment system and the central display and control components, such as MMI and Audi virtual cockpit.
LIN (local interconnect network) buses complement the CAN buses by operating less complex integrated systems such as interior lighting. The 3D Bang & Olufsen Sound System, the TV tuner and the Audi virtual cockpit use MOST (media oriented systems transport) technology.
The electrical system also contributes to lightweight construction in the new A5 Coupé: enhanced topology, new aluminum cables and a fleece battery lower the weight by six kilograms (13.2 lb) compared with the previous model.
