Claim 0:
1. A blade control device comprising:
a blade of a work vehicle;
a corrected design surface generation unit that generates a corrected design surface connecting a first surface existing in front of the work vehicle of an initial design surface indicating a target shape of an excavation object to be excavated using the blade of the work vehicle and a second surface of the initial design surface, the second surface touching the first surface and having a different slope from a slope of the first surface on the initial design surface; and
a blade control unit that outputs a control command to control a height of the blade based on the corrected design surface,
wherein the corrected design surface generation unit generates the corrected design surface when a prescribed correction condition is satisfied, and
the correction condition is a condition that a traveling speed of the work vehicle entering the first surface is a speed threshold or more.
