Problems solved by technology
[0003] In the existing technical solution, if the intelligent lawn mower encounters a relatively narrow area during the mowing operation, the intelligent lawn mower cannot enter the next operation area through the difficult area according to the current path planning scheme. Thus affecting the operating range of smart lawn mowers

Embodiment 1
[0032] This embodiment proposes a control method for improving the operating coverage of an intelligent lawn mower, such as figure 1 As shown, the control method includes:
[0033] Step 1, make the smart lawn mower drive out from the charging station and move along the perimeter line, and obtain the distance value between the surrounding environment obstacles and the smart lawn mower at preset time intervals during the driving process;
[0034] Step 2, selecting the corresponding position parameter when the distance values are greater than the preset threshold value, and recording the perimeter position corresponding to the position parameter as the entry point;
[0035] Step 3, repeat the operation from step 1 to step 2 to determine all the entry points in the perimeter area;
[0036] Step 4: When the intelligent lawn mower completes the mowing operation in the first operation area in the fenced area, and judges based on the known path that the second operation area in the...

The invention provides a control method for improving the operation coverage rate of an intelligent lawn mower, and belongs to the field of navigation. The method comprises the following steps: acquiring barrier-free coordinate points without known obstacles within a preset distance; when the intelligent lawn mower completes the mowing operation in a first operation area, judging a difficult passing area that is needed to pass through to reach a second operation area based on a known path, allowing the intelligent lawn mower to drive along a boundary line to a nearest target barrier-free coordinate point to the second operation area, and allowing the intelligent lawn mower to drive into the second operation area for mowing through the target barrier-free coordinate point. By determining the barrier-free coordinate points, the intelligent lawn mower can accurately cut into the next operating area for mowing in virtue of the obstacle-free coordinate points of the boundary line after completing the mowing operation in the previous operation area in the face of a narrow path with accurate driving errors, so that the continuous mowing operation is guaranteed, the boundary bypass distance is shortened, the lack of operation area caused by large-scale bypass is avoided, and the coverage rate of mowing operations is ensured.
Description
technical field [0001] The invention belongs to the field of navigation, in particular to a control method for improving the operation coverage of an intelligent mower. Background technique [0002] When the current intelligent lawn mower performs weeding operations in the operation area, once the power is insufficient, it needs to drive out of the operation area to the charging station for charging. When the charging is completed, it will drive into the operation area to continue weeding operations. [0003] In the existing technical solution, if the intelligent lawn mower encounters a relatively narrow area during the mowing operation, the intelligent lawn mower cannot enter the next operation area through the difficult area according to the current path planning scheme. Thereby affecting the scope of work of the intelligent lawn mower. Contents of the invention [0004] In order to solve the shortcomings and deficiencies in the prior art, the present invention provide...
