ETSI TS 101 556-2 provides a specification of the communication system required to support the requirements of Tyre Information System (TIS) application, TPG (Tyre Pressure Gauge) application and TPG operator application.

The TIS application has the objective to monitor in real time the pressure of the vehicle tyres, to advise the driver and to support him for the tyre(s) refilling if one or several tyre(s) are not at the recommended pressure. TPG application and TPG operator application have the objective to notify the TPG to road users and provide tyre pressure refilling service to vehicles, either manually, or automatically. Consequently, the communication system specification considers the various phases of the driver support process starting with the provisioning of available Tyre Pressure Gauge (TPG) locations, pairing the vehicle with a selected TPG and ensuring the data elements exchange required for the selected TPG to refill the concerned tyre(s) until reaching recommended pressure(s).

The present document is developed in accordance with requirements defined in CEN EN 16661 [1].
