Anyone who believes that only Google and Co. are busy collecting data is wrong. Meanwhile, tire manufacturers are working hard to ensure that their tires also transmit important information. This has some advantages, but it also clearly scratches the data protection rights in this country.
Of course, the driver doesn't notice anything from the little detectives in the tire. (Photo: Continental) Tires are not just round and black. They establish contact between the vehicle and the road, so they are an important safety factor. But tires can do more than just provide grip, short braking distances or a dynamic driving experience. They collect data for the communication of Car-2-Car and Car-2 infrastructure (Car2X) using sensors and transmit it to the traffic control center. Tires thus make an important contribution to a networked mobility world, which is necessary for future autonomous driving. Sensors are already used in car tires today. With a direct measuring tire air pressure control system, they check tire pressure and temperature in each wheel. The wheel sensor sends the data and an identification code to a control unit. A pressure loss can thus be displayed for each individual wheel. But the sensors can do even more. For example, the new Porsche 911 Turbo S has a sensor system that provides very precise information about whether the tires are already warm enough for certain driving maneuvers deliver paid for a long time. (Photo: Michelin) A topic that has long been established in motorsport. For two years now, tire manufacturer Michelin has been using the "Track Connect" app in combination with the Pilot Sport Cup 2 UHP tire to enable racing enthusiasts to analyze their driving profile and adapt the air pressure to the conditions on the racetrack. Here, too, sensors are integrated into the tire that collect data such as temperature and air pressure. These are continuously compared with the values entered in advance for the racetrack, road and weather conditions and signal the driver, if necessary, to adjust the air pressure in order to increase his performance. In addition, the driver can call up additional information about the vehicle, for example about oversteer or understeer behavior depending on the tire pressure at the front or rear wheels. If the driving app is more about driving fun, the sensors and their data are used in logistics. and transport industry to reduce costs and prevent tire-related failures and thus vehicle downtime. Advantages for truck and bus fleets Truck tires will also provide data for logistics in the future. (Photo: Michelin) For the truck and bus fleets, the data-based evaluation of the tires is about to be standardized. Air pressure, temperature, tire tread and tire condition are checked in real time. Vehicle and tire manufacturers such as Goodyear or Michelin as well as service providers offer software solutions to transmit this relevant tire data to fleet managers, so that in an emergency not only the driver receives information about the critical condition of his tires, but also the fleet manager. Possible damage due to incorrect tire pressure can be recognized earlier, worn or damaged tires can be replaced before they burst on the track. Fuel consumption can also be reduced with correctly filled tires. Car tires can also report Of course, car tires should also be used as communication talents. Tire monitoring using sensors and cloud-based algorithms also enables the analysis of tread wear, temperature fluctuations and tire pressure that is too high or too low. Of course, the driver's driving style and its influence on tire wear can also be analyzed in this way. What the sensors can transmit is astonishing. (Photo: Michelin) Such a system also has advantages for car sharing providers. You can order a vehicle to the petrol station for air refilling in good time or get a spare tire that will be installed at the next stop. The RFID chip can be used to digitally arrange a tire change appointment with the vehicle owner. The RFID chip Another option to generate data are so-called RFID chips. RFID stands for radio frequency identification. Such a chip weighs less than a gram and does not require a battery. Michelin, for example, plans to add such a chip to every tire by 2023. RFID enables tires to be identified by the vehicle. The car's on-board computer recognizes whether winter or summer tires are fitted and can adapt the vehicle's maximum speed to the requirements. ABS, ESP and other safety systems can also be adapted to the tires. The tire pressure can be checked very easily. (Photo: Continental) For example, mechanics, tire dealers and wholesalers can improve their logistics processes with tires that have an RFID chip. Receiving, order validation, warehouse management or even a customer assignment can be organized more easily and precisely. The tire manufacturer can track the entire life of the tire using RFID. It is used from the identification of the tires during their manufacture to the documentation of the recycling. Of course, it must be noted that a large number of data can be transmitted here that extend into the driver's personal rights. In this respect, even if these systems are finally installed in tires and vehicles, the consent of the owner or the driver must be obtained as to whether the data collected may be transferred anywhere.
