Electronic device and method of protection against overturning for agricultural, forestry and public works vehicles

electronic device for protection against overturning for agricultural, forestry and public works composed of a protective structure (2) vehicles, inverted U-shaped or T, which follows a circular from the lowered position (29) to the position movement of work. The movement occurs when the electronic control unit of the anti-roll system (26) detects danger of accident based on the data supplied by a set of sensors, including two or more accelerometers (11) and a triaxial inclinometer (12), in combination with data provided by the vehicle communication system (1) and rear implements and front (3) and (4). When the electronic control unit of the anti-roll system (26) detects the risk of accident automatically activates the electromagnet (8) which allows the spring action trigger (7) of the security structure.
