FIELD: machine building.SUBSTANCE: group of inventions relates to automotive industry. Air guide device comprises an air guide, a support structure, a drive element, a sensor and a control unit. Air guide is made on vehicle body. Method of reducing air drag of a ground vehicle includes steps of, mounting air guide on vehicle body, supporting air guide by means of a support structure, moving air guide by drive element, measuring a parameter corresponding to force applied to support structure to support air guide, generating a signal corresponding to measured parameter, controlling drive element to move air guide in response to signal and measured parameter by a desired angle of inclination, wherein measured parameter has a minimum value.EFFECT: simplified design of guiding device and improved control of air flow.17 cl, 8 dwg |
