Abstract

The invention discloses a control method and a control device for a grass mower, and the grass mower using the same. The method comprises the following steps: acquiring a first displacement signal ofa left walking wheel and a second displacement signal of a right walking wheel; calculating a target rotating speed of a grass cutter on the basis of the first displacement signal and the second displacement signal; and generating a first control instruction according to the target rotating speed so as to control a motor to rotate at the target rotating speed. The invention solves the problems ofnonuniform rotating speed and low grass-cutting efficiency of a grass hobbing cutter due to manpower limitation of the grass cutter of a hand-push type roller grass mower.

Description

Technical field [0001] This specification relates to the technical field of lawnmowers, in particular to a lawnmower control method and control device, and a lawnmower using the lawnmower. Background technique [0002] There are many types of roller lawnmowers on the market, mainly including hand-push roller lawnmowers and electric roller lawnmowers. The hand-push roller lawnmower relies on human power to push two traveling wheels to rotate, and the traveling wheels drive gears and other mechanisms to rotate, and then drive the mowing hob to rotate to trim the lawn; this hand-push roller lawnmower is mainly driven by manpower Therefore, the rotation rate of the lawn mower is limited by the size of the manpower, and the rotation speed of the lawn mower is uneven, and the cutting efficiency is low. In addition, because the two ends of the cutting hob are connected to two walking wheels, when the hand-push roller mower is cutting the grass forward, the rotation speed of the two wal...
