UNIT CONSISTING OF AN UNDERGROUND POWER SUPPLY SYSTEM AND AN ELECTRIC VEHICLE UNIT CONSISTING OF AN UNDERGROUND POWER SUPPLY SYSTEM AND AN ELECTRIC VEHICLE

摘要

This assembly, which comprises a conductive type floor feeding system (10), comprising conductive tracks (11, 12, 13) disposed on a roadway (2), and an electric vehicle (1), sensing a electrical energy from said tracks as it moves on the roadway, is characterized in that the supply system (10) comprises a ground antenna (52.i), shaped so as to have a constant radiation pattern according to a longitudinal axis (X) of the roadway and emitting a positioning signal, and in that the electric vehicle (1) comprises an on-board antenna (171, 172) and an on-board module (175) connected to the on-board antenna and adapted to determine a lateral position of a center (C1, C2) of the on-board antenna relative to the longitudinal axis (X) from the positioning signal picked up by the on-board antenna.
