Method and electronic control unit for managing at least one wireless connectivity service for at least one application in a vehicle

A method for managing at least one wireless connectivity service for at least one application in a vehicle, wherein the vehicle comprises several connectivity devices configured to run at least one wireless connection, wherein the respective wireless connectivity service is based on the at least one wireless connection, wherein operating a connectivity management unit, ICMU, performs the following steps:

• operating a link quality estimator, LQE, configured to determine a respective link quality metric, LQM, of the respective wireless connection of each of the connectivity devices,
• operating a transmission, Tx, power estimator, TPE, configured to determine a respective average radiated transmission power PT, and a respective SAR level PSAR_PWR and a respective power consumption PC of each connectivity device,
• operating a Quality-of-service, QoS, estimator, QSE, configured to determine a respective QoS mode metric, QMM, that quantifies a suitability of the respective wireless connection of each of the connectivity devices to perform the respective wireless connectivity service for at least one pre-defined traffic type t,
• operating a connectivity metric generator, CMG, configured to provide a connectivity device master map, CDMM, that lists output of the LQE, the TPE, and the QSE,
• when the at least one application signals a respective demand for the respective wireless connectivity service, determining for the respective connectivity service the respective traffic type t based on a service class of the application,
• operating a connectivity mode selector, CMS, configured to select for each application at least one of the connectivity devices for which a connectivity evaluation function yields a maximized result, wherein the connectivity evaluation function maps a pre-defined data set or data sub-set of the CDMM for the determined traffic type t onto a respective evaluation value,
• establishing the respective wireless connectivity service using the respective wireless connection of each selected connectivity device.
