A vehicle system for an autonomous or semi-autonomous motor vehicle, comprising: a sensory system comprising a plurality of sensors for generating vehicle data packets comprising information about a surrounding environment of said motor vehicle; a localization system for generating localization data packets related to said motor vehicle, said localization data packets comprising at least one of a heading of said motor vehicle and geographical coordinates of said motor vehicle; a communication system for wirelessly transmitting and receiving data to/from at least one other motor vehicle; a control unit operatively connected to said sensory system, said localization system, and said communication system, characterized in that said control unit is configured to: retrieve a first measurement of a position of an object in said surrounding environment relative to said motor vehicle by means of said sensory system; retrieve said heading and/or said geographical coordinates of said motor vehicle; receive external vehicle data packets and external localization data packets from a different motor vehicle, said external vehicle data packets comprising a second measurement of a position of said object relative to said different motor vehicle and said external localization data packets comprising at least one of a heading of said different motor vehicle and geographical coordinates of said different motor vehicle; retrieve a position of said different motor vehicle relative to said motor vehicle by means of said sensory system; translate said external vehicle data packets to a local coordinate system by comparing said position of the different motor vehicle relative to said motor vehicle, said localization data packets and said external localization data packets; and process said translated external vehicle data packets and said vehicle data packets in order to generate a probable position of said object. a sensory system comprising a plurality of sensors for generating vehicle data packets comprising information about a surrounding environment of said motor vehicle; a localization system for generating localization data packets related to said motor vehicle, said localization data packets comprising at least one of a heading of said motor vehicle and geographical coordinates of said motor vehicle; a communication system for wirelessly transmitting and receiving data to/from at least one other motor vehicle; a control unit operatively connected to said sensory system, said localization system, and said communication system, characterized in that said control unit is configured to: retrieve a first measurement of a position of an object in said surrounding environment relative to said motor vehicle by means of said sensory system; retrieve said heading and/or said geographical coordinates of said motor vehicle; receive external vehicle data packets and external localization data packets from a different motor vehicle, said external vehicle data packets comprising a second measurement of a position of said object relative to said different motor vehicle and said external localization data packets comprising at least one of a heading of said different motor vehicle and geographical coordinates of said different motor vehicle; retrieve a position of said different motor vehicle relative to said motor vehicle by means of said sensory system; translate said external vehicle data packets to a local coordinate system by comparing said position of the different motor vehicle relative to said motor vehicle, said localization data packets and said external localization data packets; and process said translated external vehicle data packets and said vehicle data packets in order to generate a probable position of said object. retrieve a first measurement of a position of an object in said surrounding environment relative to said motor vehicle by means of said sensory system; retrieve said heading and/or said geographical coordinates of said motor vehicle; receive external vehicle data packets and external localization data packets from a different motor vehicle, said external vehicle data packets comprising a second measurement of a position of said object relative to said different motor vehicle and said external localization data packets comprising at least one of a heading of said different motor vehicle and geographical coordinates of said different motor vehicle; retrieve a position of said different motor vehicle relative to said motor vehicle by means of said sensory system; translate said external vehicle data packets to a local coordinate system by comparing said position of the different motor vehicle relative to said motor vehicle, said localization data packets and said external localization data packets; and process said translated external vehicle data packets and said vehicle data packets in order to generate a probable position of said object.
