A digital chassis twin for predictive driving functions and component status updates
Every new generation of Porsche benefits from the improved performance of its integrated sensors, networking and data processing capabilities, which in turn uncovers new possibilities for effectively using these capabilities. One of these possibilities is known as a ‘digital twin’.
The digital twin of a vehicle comprises not only the operating data it collects but also any related data, such as information collected during planned maintenance work and unexpected repairs. Elements of this digital twin already exist in control unit memories and in the databases maintained at Porsche Centres.
Centralised intelligence system for data
Conclusions that benefit every single vehicle and therefore every individual customer can be drawn from data relevant to an entire field. For example, an algorithm can compare big data against sensor data from a specific vehicle's powertrain and chassis to identify a customer's driving style. This data makes it possible to customise service intervals and allow servicing for specific components as needed, based on how the customer uses their vehicle.
High importance of the chassis
The reason for focusing on chassis components is clear: on a Porsche, the chassis is subjected to the highest loads, particularly when the vehicle is used on racing circuits. Sensor technology in the vehicle and the intelligent neural algorithms used for centralised analysis allow the load on the chassis to be detected within the vehicle and conveyed to the driver. This intelligent use of data makes the vehicle safer for its passengers because any specific faults are identified immediately, even before the driver or the workshop notices a problem signified by noise or vibration.
The data is evaluated and transferred via Porsche Connect to the central backend system. This system continuously compares the data from each vehicle against the fleet data.
Artificial intelligence and data privacy
Data privacy during the testing phase and after the series production launch is the top priority so customers are prompted via the PCM to provide their consent to data being collected anonymously.
The first version of the digital twin will be launched next year and only sensor data directly from mechatronic components will be evaluated. For example, if multiple vehicles require adjustments to their wheel alignment or a track rod replacement and multiple sensors have already detected corresponding deviations, this information can indicate a pattern. If the same data is then identified on a further vehicle, the driver will accordingly be told to visit a Porsche Centre.
