Vibration Roller Control Device, Control Method, and Vibration Roller

A control method for controlling a vibrating roller that generates vibration on a drum by rotating a vibration exciting shaft including an eccentric weight provided inside one or both of a front wheel and a rear wheel with respect to a proceeding direction by a vibration exciting motor, the control method comprising:

• calculating a front wheel vibration start timing for starting vibration of the front wheel and calculating a rear wheel vibration start timing for starting vibration of the rear wheel, the front wheel vibration start timing and the rear wheel start vibration timing representing a time width required from the start of vibration of each of the front wheel and the rear wheel until a desired vibration frequency is obtained at a time before the front wheel and the rear wheel reach a boundary position of a road surface to be constructed;
• starting vibration of the drum, which is the front wheel, so as to provide vibration a predetermined number of times to the road surface to be constructed per unit length;
• starting vibration of the front wheel based on the calculated front wheel vibration start timing;
• starting vibration of the rear wheel based on the calculated rear wheel vibration start timing;
• calculating a timing at which the drum, which is the front wheel, starts vibration and the drum, which is the rear wheel, is able to vibrate the road surface to be constructed the predetermined number of times per unit length;
• starting vibration of the drum, which is the rear wheel, at the calculated timing;
• and
• set timings at which the front wheel and the rear wheel pass the same position on the road surface to be constructed.
