Abstract
The present invention relates to a method of controlling operation of a vibratory roller (1) comprising a roller drum (3) and a vibratory mechanism (2) having at least two amplitude settings. The method comprises operating the vibratory mechanism (2) in one of said at least two amplitude settings; maintaining a predefined phase angle by controlling the vibration frequency of the vibratory mechanism (2); monitoring a bouncing indication value (BIV), said bouncing indication value being calculated based on an acceleration signal indicative of the vertical acceleration of the roller drum (3); and turning off the vibratory mechanism (2) upon detection of a resonance meter value (BIV) that exceeds a predetermined bouncing value (BV), thereby preventing the vibratory roller from operating in a bouncing mode of operation.
