A freight transport vehicle comprising: - a frame defining a loading area and having a longitudinal median axis lying on a vertical median plane; - a plurality of independent steering trolleys forming two rows, of trolleys, arranged on opposite sides of said vertical median plane in a position spaced from the vertical median plane; each trolley having at least one wheel rotating about a rolling axis and designed to roll in contact with a rolling surface, and being rotatably hinged to the frame about a respective vertical hinge axis orthogonal to said rolling axis; - for each of said trolleys, a respective steering motor for rotating said trolley with respect to said frame about the respective vertical hinge axis; and - a drive and control unit of said motors to drive the frame with reference to a reference trajectory along said rolling surface; said drive and control unit comprising detection means to detect a deviation of the vehicle from said reference trajectory during the progress of the vehicle and a processing and control unit configured to control said motors in response to detection signals received from said detection means; characterized in that said detection means comprising two independent optical detectors; each of said optical detectors being designed to send a respective deviation signal with respect to a reference condition to said processing and control unit; said optical detectors being both crossed by said vertical median plane and mutually spaced along said median symmetry axis; said processing and control unit being configured to process the received deviation signals and determine a centre of instantaneous rotation of the vehicle and to control at least part of the motors and rotate the relative trolleys, each about its own vertical hinge axis, so that all the rolling axes intersect in said centre of instantaneous rotation. - a frame defining a loading area and having a longitudinal median axis lying on a vertical median plane; - a plurality of independent steering trolleys forming two rows, of trolleys, arranged on opposite sides of said vertical median plane in a position spaced from the vertical median plane; each trolley having at least one wheel rotating about a rolling axis and designed to roll in contact with a rolling surface, and being rotatably hinged to the frame about a respective vertical hinge axis orthogonal to said rolling axis; - for each of said trolleys, a respective steering motor for rotating said trolley with respect to said frame about the respective vertical hinge axis; and - a drive and control unit of said motors to drive the frame with reference to a reference trajectory along said rolling surface; said drive and control unit comprising detection means to detect a deviation of the vehicle from said reference trajectory during the progress of the vehicle and a processing and control unit configured to control said motors in response to detection signals received from said detection means; characterized in that said detection means comprising two independent optical detectors; each of said optical detectors being designed to send a respective deviation signal with respect to a reference condition to said processing and control unit; said optical detectors being both crossed by said vertical median plane and mutually spaced along said median symmetry axis; said processing and control unit being configured to process the received deviation signals and determine a centre of instantaneous rotation of the vehicle and to control at least part of the motors and rotate the relative trolleys, each about its own vertical hinge axis, so that all the rolling axes intersect in said centre of instantaneous rotation.
