Abstract

The autonomous working apparatus is adapted to perform at least one working task in a working area. A control method includes: obtaining at least one working parameter when the autonomous working apparatus performs a current working task; determining, according to the at least one working parameter, whether the autonomous working apparatus needs to return to a preset parking position located outside the working area, and if a determining result is yes, controlling the autonomous working apparatus to travel to a preset position to wait for a user operation to be applied, where the preset parking position is different from the preset position; and enabling the autonomous working apparatus to return to the preset parking position based on the applied user operation, and switching to a state of waiting to perform a next working task or shutting down.

First claim

What is claimed is:

1 . A method for controlling an autonomous working apparatus, the autonomous working apparatus adapted to perform at least one working task in a working area, the method comprising:
obtaining at least one working parameter when the autonomous working apparatus performs a current working task; determining, according to the at least one working parameter, whether the autonomous working apparatus needs to return to a preset parking position located outside the working area, and if a determining result is yes, controlling the autonomous working apparatus to travel to a preset position to wait for a user operation to be applied, wherein the preset parking position is different from the preset position; and enabling the autonomous working apparatus to return to the preset parking position based on the applied user operation, and switching to a state of waiting to perform a next working task or shutting down.

2 . The method according to claim 1 , wherein position data of the preset position comprises position data of an entry position when the autonomous working apparatus enters the working area.

3 . The method according to claim 2 , wherein the position data of the entry position comprises position data of a position at which course calibration is completed after the autonomous working apparatus enters the working area.

4 . The method according to claim 1 , before the autonomous working apparatus performs a working task, further comprising obtaining map data of the working area, wherein the map data comprises position data of the preset position.

5 . The method according to claim 4 , wherein the obtaining the map data of the working area comprises:
acquiring position data of a boundary of the working area and the position data of at least one preset position; and generating the map data according to the acquired position data.

6 . The method according to claim 4 , wherein the obtaining the map data of the working area comprises:
acquiring position data of a boundary of the working area and position data of a guide line or a guide area for guiding the autonomous working apparatus to travel into the working area from outside the working area, wherein the position data of the guide line or the guide area comprises the position data of at least one preset position; and generating the map data according to the acquired position data.

7 . The method according to claim 1 , wherein the preset position is located inside and/or at a boundary of the working area.

8 . The method according to claim 1 , wherein the preset parking position is located on a moving tool near the working area, and the moving tool is configured to transport the autonomous working apparatus to a different working area to perform a working task.

9 . The method according to claim 1 , wherein the at least one working parameter comprises an execution progress of the current working task.

10 . The method according to claim 9 , wherein the enabling the autonomous working apparatus to travel to the preset parking position based on the applied user operation comprises:
receiving an instruction entered by a user to return to the preset parking position; and controlling the autonomous working apparatus based on the instruction to return to the preset parking position.

11 . The method according to claim 9 , wherein the enabling the autonomous working apparatus to travel to the preset parking position based on the applied user operation comprises:
receiving an instruction entered by a user to switch to a manual mode; and controlling the autonomous working apparatus based on the instruction to switch to the manual mode, wherein in the manual mode, the autonomous working apparatus returns to the preset parking position based on control of the user.

12 . The method according to claim 9 , wherein the at least one working parameter further comprises a remaining battery level of the autonomous working apparatus, and the method further comprises:
determining, according to the remaining battery level of the autonomous working apparatus, whether the autonomous working apparatus needs to replenish electricity, and if a determining result is yes, controlling the autonomous working apparatus to travel to at least one preset position to wait for a user to replenish electricity.

13 . The method according to claim 12 , wherein the method further comprises:
receiving an instruction entered by the user to end replenishment of electricity; and controlling the autonomous working apparatus based on the instruction to drive away from the at least one preset position and continue to perform the current working task.

14 . A method for controlling an autonomous working apparatus, the autonomous working apparatus adapted to perform at least one working task in a working area, the method comprising:
obtaining position data of an entry position when the autonomous working apparatus enters the working area; obtaining at least one working parameter when the autonomous working apparatus performs a current working task; and determining, according to the at least one working parameter, whether a user operation needs to be applied to the autonomous working apparatus, and if a determining result is yes, controlling the autonomous working apparatus to travel to the entry position to wait for the user operation to be applied.

15 . A method for controlling an autonomous working apparatus, the autonomous working apparatus adapted to perform at least one working task in a working area, the method comprising:
obtaining position data of a plurality of preset positions, wherein the autonomous working apparatus waits at the preset positions for a user operation to be applied; obtaining at least one working parameter when the autonomous working apparatus performs a current working task; and determining, according to the at least one working parameter, that a user operation needs to be applied to the autonomous working apparatus; and controlling the autonomous working apparatus to travel to one preset position in the plurality of preset positions to wait for the user operation to be applied.

16 . The method according to claim 15 , wherein the controlling the autonomous working apparatus to travel to one preset position in the plurality of preset positions to wait for the user operation to be applied comprises:
obtaining position data of a preset position selected by a user from the plurality of preset positions in response to a position selection instruction sent by a user terminal, and controlling the autonomous working apparatus to travel to the preset position selected by the user to wait for the user operation to be applied.

17 . The method according to claim 15 , wherein the controlling the autonomous working apparatus to travel to one preset position in the plurality of preset positions to wait for the user operation to be applied comprises:
obtaining position data of a default preset position in the plurality of preset positions, and controlling the autonomous working apparatus to travel to the default preset position to wait for the user operation to be applied.
