“We want to always show our customers an honest indication of the remaining range that they can easily reach driving in their own style. That’s why our smart calculation system takes all eventualities into account – whether daylight savings and bumper-to-bumper vacation traffic or winter weather and the demands of increased heating. Reliability and honesty in terms of range are the key prerequisites to dispel reservations about e-mobility and permanently relieve range anxiety. This is the approach our remaining range display follows so that drivers can rest assured that they will reach their destination as planned,” says Audi Head of Product Marketing Christiane Zorn.
Consumption historical past, outdoors temperature, and different parameters make for a practical calculation
Predictive, reliable, and dynamic: Audi e-tron fashions give drivers the selection between two totally different choices to calculate the vary, one with and one with out the route planner as a part of the Audi Multi Media Interface (Audi MMI). Without the technical help of the satnav and the route planner, the calculation of the remaining vary rests on current consumption values. The system additionally displays driver-specific properties, akin to an particularly sporty or economical driving type. Isolated particular elements, akin to energy-intensive passing maneuvers, are reliably averaged out, making certain a practical calculation.
In addition to consumption knowledge from the drive and onboard energy techniques, the automobile’s distribution level and electrical nervous system, remaining vary calculation additionally elements in thermal administration knowledge (heating or AC) or the usage of further consolation options akin to seat or steering wheel heating. Also thought of are the chosen driving mode, particular person automobile configuration, load, and climactic situations. In this fashion, the vary display represents the newest consumption knowledge and tasks them into the long run, with out further knowledge from the route planer.
Clever algorithms acknowledge the distinction between laid-back nation driving and winding roads
For route-based vary calculation, the current consumption knowledge is supplemented with further knowledge from the route planner, which is obtainable in all e-tron fashions. This means the system considers the topography alongside the deliberate route in addition to divides the deliberate route into sections for calculation functions. Each stage of the route is then assigned an anticipated driving velocity. This effective division into small sections facilitates extremely exact calculation. Other parameters used embody the likelihood of open freeway alongside the route and anticipated congestion. Urban visitors, visitors jams, blocked visitors, velocity limits, and major via roads all have a dwell affect on the calculation. Unlike retrospective vary display, route-based calculations are able to differentiating, from the second a journey begins, whether or not it’s a laid-back drive down nation roads at a mean of 80 km/h and summer time temperatures or a journey to your subsequent ski trip on highways and winding roads in a frosty atmosphere with the warmth on full blast.
No exterior knowledge connection: Calculation takes milliseconds proper in the car
Data evaluation highlights embody dynamic adjustment of the remaining vary that takes exterior and vehicle-related elements under consideration. External elements embody real-time congestion knowledge, which is gathered repeatedly and instantly mirrored in the calculation.
Examples of vehicle-related elements embody adjustments in utilization conduct associated to consolation options or sudden adjustments in driving conduct. If, for instance, the heating or air con is switched on or off, the remaining vary is instantly recalculated, usually ensuing in seen changes to the vary display. This lets drivers see, at a look, how their conduct impacts the vary. With the computing energy being positioned instantly in the car in Audi e-tron fashions, knowledge calculation takes solely a few milliseconds. This eliminates the necessity for a connection to an exterior knowledge processor. As a outcome, the system capabilities autonomously and isn’t depending on ample cellular knowledge protection.
The Audi e-tron route planner is a new software program improvement that was first used in all-electric fashions in the MIB 2+ era of the modular infotainment toolkit. Since 2020, the third era of the modular infotainment toolkit (MIB 3) has introduced even higher performance to the e-tron route planner with ten instances the computing energy. The on a regular basis utility of the superior route planner is additional elevated by a new algorithm: Daily up to date knowledge on charging factors and different routes, each optimized for the necessities of e-vehicles, lend drivers improved help. Examples of every day up to date knowledge embody detailed info akin to fee and authentication choices, exact operator knowledge, and any entry restrictions.
Time-optimized route planning favors high-power charging
When trying for appropriate charging factors alongside the route, Audi makes certain there’s all the time a reliable basis for planning with the route planner. To make sure the shortest potential journey time, solely as many charging stops are instructed as are mandatory to succeed in the vacation spot safely. If the route or consumption change, for instance as a consequence of unexpected visitors jams or the use or deactivation of consolation options, potential or mandatory charging stops are additionally adjusted. For instance, two quick stops to cost at a station with high-power charging factors can save time in comparison with one lengthy cease at a charging station with lower-power charging factors. Alternative routes with higher charging infrastructure are additionally thought of when calculating the ideal whole journey time. The Audi e-tron route planner favors HPC (high-power charging) charging stations.
