Porsche is developing digital twin technology, Provide early maintenance warnings to car owners, remind car owners to pay attention to dangerous road conditions in advance, and even help car owners get the most benefits when selling or changing cars.
Simply put, a digital twin is a virtual copy of an existing object. Whether it is a vehicle, a system or a component, the user can monitor, diagnose, and even perform data-driven analysis on it, without interacting with the physical car or component. . Porsche has been developing digital twin technology for its Taycan all-electric car for three years. So far, the focus of the car manufacturer is the chassis, which is the most important part of the car, and it has to withstand continuous high loads.
The development of the digital twin is managed by Cariad, an independent software company of the Volkswagen Group that focuses on automobiles. In view of its relationship with this large organization, Porsche can obtain information from all vehicles of the Volkswagen Group, which increases the amount of data it can use by 20 times. Digital twin technology can realize maintenance alert. After hitting a pothole, the vehicle can predict that one of its shock absorbers may need to be replaced in the next two weeks. This judgment is made by data collected by the body acceleration sensor. The car can then warn the driver of an impending failure, and even remind the owner’s preferred dealer so that they can prepare the relevant parts for a seamless service experience.
Porsche Taycan’s air suspension system is already undergoing such monitoring, and about half of the car owners choose to participate in a pilot project. Data about body acceleration is collected and sent to a back-end system that compares this information with other vehicles in the fleet. If the threshold is exceeded, the driver will be reminded to inspect their car to determine whether there is potential damage. Privacy is very important to Porsche. Car owners must choose to share any data, and all data is anonymous. The data is preprocessed in the car to minimize the amount of transmission, but the owner can disable this information transmission at any time. Safety is Porsche’s top priority.
The same thing can be done on the power system. By comparing the data collected from the owner’s vehicle with the information collected from other drivers’ vehicles, the owner’s driving style can be determined. This information can be used to customize service cycles and even remind technicians to check specific parts, which can save time, improve safety, and prevent future maintenance problems.
Getting digital twins can also help technicians diagnose intermittent problems. If the suspension clanging only occurs somewhere in a specific parking lot, the digital twin can show what input caused the noise, at what steering angle and vehicle speed it might occur. With this additional information, service providers can more easily identify and fix stubborn problems.
