Porsche is developing a digital twin, a service that centrally collects data from in-vehicle sensors and converts it into big data to quickly detect individual vehicle failure signs and alert users.
If the current car is properly inspected regularly so that it does not break down suddenly, it is possible to know in advance when to replace consumables. However, this is an indication of a failure that cannot be detected unless it is time for an inspection. For example, it is only after a certain period of time has passed that it is known that failures or signs that occur frequently in the same model can be detected by inspection.
The digital twin function being developed by Porsche creates individual body digital twins using sensor data from the car. In addition, the AI algorithm derives a recommended inspection service suitable for driving style and driving history by matching it with big data collected from other vehicles running in large quantities.
For example, a person who runs long distances for daily commuting will increase the consumption around the engine, and for a person who drives a lot of sports on a circuit, the surrounding environment such as suspension will be intense. As the deterioration state of each part naturally appears in the data, it is possible to quickly recognize them with a big data combination and predict failures. If the prediction is accurate, the likelihood of a user being in an accident or any danger due to a sudden breakdown is reduced, and consequently the repair cost is not increased.
The official announcement of the digital twin function is expected after 2022. The service will be launched using sensor information collected from the Porsche Taycan. Currently, half of Taycan owners are anonymously participating in the data offering, and are conducting pilot tests that measure car acceleration from suspension data. If there is a vehicle body whose data exceeds a certain threshold, an inspection prompt notification is sent to the owner.
When this system is deployed on a large scale, automakers will be able to provide inspection notices or advice at appropriate times for each vehicle rather than in the form of regular inspections. In addition, even if the vehicle is passed to another owner, since the data on how the vehicle has been handled in the past is left as data, transparency from the buyer’s point of view will increase, making it easier for the seller of the used car to set the price or extended warranty.
