With its diverse range of new driver assistance systems, the Audi A3 raises the bar in the premium compact class even higher. Some of these systems, such as the attention assist, are even standard equipment. Optional solutions are available separately or as assistance packages.
In town and country: more safety
From a speed of 65 km/h (40.4 mph), Audi active lane assist helps the driver to stay in the driving lane. Its signal source is the front camera that recognizes markings on the road. Once the new Audi A3 approaches a lane marking without the turn signal being operated, the system assists the driver by means of a slight intervention in the electromechanical steering system, and steers the car back into its lane. By means of the MMI system the driver can choose whether this support should take place at an early stage or only shortly before crossing the line. If the driver opts for early intervention, the system will also guide the car to the center of the lane. In addition, the driver can set a steering wheel vibration as a warning signal.
Audi pre sense front
The optional Audi pre sense front system, including predictive pedestrian protection, scans the road for other vehicles through the entire speed range and up to 65 km/h (40.4 mph) for pedestrians. On threat of a collision, the system warns the driver according to a graduated concept: If necessary, it initiates automatic partial braking, and depending on the situation full deceleration as well. Depending on the situation, a brake intervention can either completely avoid an accident or mitigate its severity thanks to a lower collision speed. If necessary, Audi pre sense basic also kicks in, initiating preventive measures to protect the occupants. The front seat belts are electrically tensioned, and the windows and the sunroof are closed.
Traffic jam assist
In slow-moving traffic at speeds of less than 65 km/h (40.4 mph), the optional traffic jam assist takes over not only the following distance but if necessary also the steering. Based on the data acquired from radar sensors and the front camera, the assist drives the car within the system limits, if adaptive cruise control is active. The traffic jam assist positions itself using the road markings and the preceding vehicles, among other things.
The emergency assist (only with S tronic) is enabled if, despite warnings with braking jolts, acoustic signals and flashing, no steering activity by the driver is detected. If the driver continues not to respond, the system initiates braking up to a safe stop through slight decelerations, if adaptive cruise control is enabled.
The optional adaptive cruise control (ACC) Stop&Go driver assistance system keeps the new Audi A3 at a safe distance from the preceding vehicle. The driver can then choose between five distances and adjust acceleration and dynamics in the control system via Audi drive select. Utilizing the signals from the front radar sensor and in interplay with the S tronic, the system covers the full speed range from 0 to 200 km/h (124.3 mph); with manual transmission coverage begins at 30 km/h (18.6 mph).
The Stop&Go function of the ACC (only with S tronic) brakes the new A3 up to a full stop and lets it start off again automatically at the driver’s request. If the system’s distance control function is disabled, the distance indicator shows the time gap to the preceding vehicle as of 65 km/h (40.4 mph) and warns the driver about approaching too closely.
The camera-based recognition of traffic signs completes the lineup of driver assistance systems. It detects many different kinds traffic signs, including digital displays and auxiliary signs, and presents them to the driver as graphics in the instrument cluster. In addition, the driver can opt for a visual warning if the sign-based speed limit is exceeded. A design-related maximum speed for trailer operation can be set.
The new cross traffic assist rear is enabled when the parking system is activated. In this case, the cross traffic assist rear warns the driver of approaching vehicles it deems critical when slowly reversing, as when pulling out of a perpendicular parking spot. The warning occurs in graduated form – visually and if necessary acoustically as well as with a warning jolt. The data from the rear radar sensor serve as the basis.
The systems for convenient parking are headed by the park assist. Its twelve ultrasonic sensors can detect obstacles anywhere surrounding the new Audi A3. The park assist relieves the driver’s steering work when entering parking spaces; if necessary it also intervenes in multiple stages – and now also moves the vehicle forward into perpendicular spaces. The rearview camera (with trailer towing hitch in trailer mode) is a useful supplement in spots with obstructed views.
