DYNAMIC CONTROL OF VEHICLE DRIVETRAIN MODES OPERATED IN RESTRICTED EMISSION TRAFFIC ZONES, BASED ON REAL-TIME AIR QUALITY MEASUREMENTS

A computer-implemented method for establishing at least one low or zero emission traffic zone and for controlling and monitoring a momentarily operated drivetrain of hybrid vehicles (402) passing through the at least one established low or zero emission traffic zone is provided. The method includes: acquiring (202, 210) data from air quality-sensitive sensors (510) placed within a region (604) including the at least one low or zero emission traffic zone to be established; operating a cloud-based service for evaluating (200) the acquired data regarding air quality; wirelessly transmitting signals (302) representative of a location and a shape of the at least one low or zero emission traffic zone to hybrid vehicles (402); operating (308) vehicle-based mode transition means (408) for at least initiating a change of a drivetrain mode of the hybrid vehicle (402) to electric mode; generating (310) a blockchain data block including data regarding the current position and the momentarily operated drivetrain of the hybrid vehicle (402); and adding (312) the generated blockchain data block to a blockchain residing in a blockchain system (508).
