Tires can do more than just provide good grip and short braking distances. Using sensors, they are able to collect and transmit important information.
For example, they can transmit data for the communication of car-2-car and car-2 infrastructure (Car2X). Tires make an important contribution to a networked mobility world, which is necessary for future autonomous driving, for example. The data analysis also helps to save costs.
Sensors are already being used in car tires today. With a directly measuring tire pressure monitoring system, you check the tire pressure and temperature in each wheel. The wheel sensor sends the data and an identification code to a control unit. A pressure loss is displayed for each wheel. But sensors can do more. The new Porsche 911 Turbo S, for example, has a sensor system that provides very precise information on whether the tires are already warm enough for certain driving maneuvers.
Connectivity established in racing
The subject of tire connectivity is already well established in motorsport. For two years now, tire manufacturer Michelin has been using the “Track Connect” app in combination with the UHP Pilot Sport Cup 2 tire to enable racing enthusiasts to analyze their driving profile and adjust the air pressure to the conditions of the race track. The system collects temperature and air pressure data via sensors integrated in the tire.
These are continuously compared with values entered in advance for the racetrack, road and weather conditions and, if necessary, signal the driver to adjust the air pressure in order to increase his performance even further. In addition, the driver can call up further information on the vehicle, for example on oversteer or understeer behavior depending on the tire pressure on the front or rear wheels.
Reducing costs in logistics
If driving fun is more in the foreground with the racing app, sensors and their data in the logistics and transport industry are used to reduce costs and prevent tire-related breakdowns and thus vehicle downtime. Data collection and evaluation for truck and bus fleets is on the way to becoming a standard. Tires that are monitored in real time by sensors (air pressure, temperature, tire profile, condition) are part of everyday fleet life. 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.
Not only does the driver receive information about a possible pressure loss, this information is also sent to the fleet manager at the same time. Possible damage due to incorrect tire pressure can be detected earlier, worn or damaged tires are recognized in good time and replaced before a tire failure can occur. By monitoring the correct air pressure, the tires last longer, and correctly inflated tires also have a positive effect on the fuel consumption of a fleet. The driving and braking style of the driver is also under observation.
Monitoring of the tire condition
Of course, car tires should also be used as communication talents. The major tire manufacturers are intensively researching the subject of sensors and their possible uses in passenger cars. Tire monitoring using sensors and cloud-based algorithms enables, for example, the analysis of tread wear, temperature and inflation pressure and a comparison of the driving style of the vehicle driver. With car sharing providers, for example, this type of monitoring can be used to order a vehicle to the gas station to refill air or to get a spare tire that can be fitted at the next stop.
For private customers, for example, the information is transmitted to the smartphone via the app and the tire dealer stored in the app is notified if a tire change should be necessary. They can make an appointment with the vehicle owner digitally to change tires.
Michelin wants to use chips
Another option for generating data are so-called RFID chips. RFID stands for Radio Frequency Identification, i.e. radio identification. Such a chip weighs less than a gram and does not require a battery. Michelin, for example, plans to provide every tire with such a chip by 2023. RFID enables the vehicle to identify tires. The car's on-board computer recognizes whether winter or summer tires are fitted and adapts the vehicle to the tires with the appropriate information on the maximum speed or adjustments to ABS, ESP and other active driving safety systems.
Fitters, tire dealers and wholesalers can, for example, improve their logistical processes with tires that have an RFID chip. Reception, dispatch order validation, warehouse management or customer assignment can be organized more easily and precisely. The tire manufacturer can use RFID to track the entire life of the tire. It serves from the identification of the tires during their manufacture to the documentation of the recycling. (SP-X)
