Display system of hydraulic shovel, and control method therefor

A display system in a hydraulic shovel having a work machine including a bucket and a main body to which the work machine is attached, the display system comprising:

• a position detector unit configured and arranged to detect information pertaining to a current position of the hydraulic shovel;
• a storage unit configured and arranged to store positional information for a design surface indicating a target shape for a work object;
• a calculation unit configured to calculate a position of a blade edge of the bucket based on the information pertaining to the current position of the hydraulic shovel, and to calculate a distance between the design surface and a position closest to the design surface among positions of the blade edge in a widthwise direction of the blade edge of the bucket based on positional information for the blade edge and the design surface;
• and
• a display unit configured and arranged to display a guidance picture including an image showing a positional relationship between the design surface and the blade edge of the bucket and information indicating the distance between the design surface and the position closest to the design surface.
