The system from US corporation Goodyear consists of a sensor-equipped car tire that constantly reports its condition and ID via mobile telephony to a cloud server, where the data is evaluated by newly developed algorithms. This makes it possible to access information on tread wear, temperature and inflation pressure at any time. Goodyear is primarily targeting the model at fleet operators such as car-sharing providers, allowing them to make optimum use of their vehicles’ tires and accurately plan workshop visits. This should prevent accidents due to bald tires, and increase mileage through continuous monitoring of air pressure.
The corresponding development from Italian tire manufacturer Pirelli is called Cyber Car . In this case the sensors deliver tire data to an app and to the vehicle systems. Cyber Car is capable of stepping in and activating systems such as ABS and stability control on the basis of the transmitted data. By reading the tire ID, the vehicle can change certain settings to improve safety and comfort. The collected data also includes vertical load – which is important for electric cars, as this allows the remaining range to be calculated more accurately.
Both tires are currently still prototypes, but are already nearly production-ready.
