Overall, new technologies allow the A6 to match up with its “model“ vehicle, the
3、Audi A8. Features, which were previously reserved for luxury vehicles, are now also available in the top- class segment.In combination with these diverse capabilities, the underlying technology has, of course, been enhanced considerably. The use of the most modern network technologies, such as CAN,
4、LIN, MOST and Bluetooth, and the related distributed vehicle functions signals the arrival of a new generation of vehicle electrics in this class. Some of these are safety-related features, such as the combined rain/light sensor or the pivoting cornering headlight. Comfort features of the top class,
5、 such as the MMI operating system or sophisticated functionalities for the mobile baseplate, which is available ex-works, are part and parcel of these new saloons.The new Audi A6 has everything that is needed to become the Number One model in the top-class range. It combines many different, attracti
6、ve components to form one unit. Design and performance go hand-in-hand.

10、ower supply and the battery. Open-circuit voltage historyIf the battery open-circuit voltage is less than the threshold values of 12.5 volts, 12.2 volts and 11.5 volts, an entry is written to the history data. The last four entries can always be read out.Voltage measurement starts when CAN Convenien
11、ce is in Sleep mode and terminal 15 is switched off for at least 2 hours and the vehicles power consumption is 50 mA.Current measurement ends when the current decreases or the control unit triggers Sleep mode.Breakdown analysisIf the control unit for power management detects the status “Cannot start
12、 vehicle“, an entry is written to the history data.Cut-off level historyData for the last 15 cut-off levels is stored.Steady battery dischargeThe battery condition is 100 % when the battery is charged. As soon as cut-off level 1 is activated, the MMI “Battery condition“ display drops to 90 % and the
13、n goes down to 60 % in steps. If cut-off level 1, 2 or 5 is set when the display reads 90 %, the message “Power-saving mode active“ appears for a short time on the central display of dash panel insert J285. In addition, the battery symbol in the dash panel insert indicates power-saving mode for the
14、entire load switch-off duration. As soon as cut-off level 3 is activated, the “Battery condition“ display drops to 50 % and then goes down to 20 % in steps. If the battery condition drops to 10 %, cut-off level 6 is active. In cut-off level 6, the message “BATTERY LOW“ appears in the central display
