“Digital twins”: Porsche’s idea to predict with AI when we will have to maintain the car

Porsche is developing an exciting new technology based on artificial intelligence and big data: the “digital twins”. In short, it is a “virtual copy of an existing object“, in this case a car, which allows analysis, monitoring and diagnosis remotely and intelligently.

The easiest way to look at it is to imagine a car full of sensors. These sensors monitor the vehicle in real time. The data obtained is crossed with those of other cars Through a centralized artificial intelligence system and, in this way, conclusions can be drawn, such as the driving style or the wear of the components and, depending on that, the optimal time to do the maintenance.

Predicting maintenance before it’s too late

As explained from Porsche, the elements of this “digital twin” are already present in the memories of the control unit and in the databases of Porsche Centers. During these last three years, the company has been working on a “chassis twin” and, in its own words, “the project now has access to those of all the Group’s models, which multiplies the information collected”.

Why focus on the chassis first? Because according to Porsche, the frame is subject to heavy loadsespecially when the car is used on the track. With this model, the firm intends to identify a possible failure in the chassis “before the driver or the workshop realizes it.”

Apparently this “digital chassis” is already being used in the Porsche Taycan. This scenario consists of monitor air suspension components collecting data on acceleration. This data is evaluated, transferred to the central intelligence system and compared with data from other similar vehicles.

Then, the algorithm calculates “thresholds based on this comparison” and, if they are exceeded, the customer is notified through the car’s communication system. This does not mean that the car has a problem, but that there may be wear that should be checked.

Regarding privacy, it will be the driver who decides if he wants to share the data or not, something that will be done anonymously. According to Porsche, the first version of the “digital twin” will be released next year and will evaluate “sensor data directly related to mechatronic components.” In the future they plan to also calculate the wear of specific components.
