Hand-held power tool
A power tool includes a housing in which a drive unit is arranged, and a tool holder for the detachable holding of a tool insert. The tool insert is configured to be driven percussively and/or rotationally. A sensor unit is configured to detect at least one movement variable, and electronics are configured to control or regulate the power tool. The electronics have a percussion detection unit configured to determine a percussion mode based on at least one movement variable and/or a rotation detection unit configured to determine a rotation of the housing. The electronics control the drive unit based on the determined percussion mode and/or the determined rotation of the housing. The electronics have at least two parameter sets for the percussion detection unit and/or at least two parameter sets for the rotation detection unit. The electronics are configured to select one of the at least two parameter sets.
1. A hand-held power tool comprising:
a drive unit;
a housing in which the drive unit is mounted;
a tool receiver configured to detachably receive an insert tool, the insert tool configured to be driven at least one of percussively and rotationally by the drive unit;
a sensor unit configured to sense at least one motion variable; and
an electronics system configured to:
control at least the drive unit by open-loop or closed-loop control;
automatically select a parameter set from at least two parameter sets;
determine a percussion mode of the hand-held power tool using the selected parameter set from the at least two parameter sets and based on the at least one motion variable; and
control the drive unit based on the determined percussion mode of the hand-held power tool,
wherein the at least two parameter sets are configured such that determination of the percussion mode by use of a first parameter set from the at least two parameter sets differs from determination of the percussion mode by use of a second parameter set from the at least two parameter sets.
2. The hand-held power tool as claimed in claim 1 , wherein a first parameter set and a second parameter from the at least two parameter sets set differ at least in a threshold.
3. The hand-held power tool as claimed in claim 1 , wherein the at least two parameter sets are configured such that control of the drive unit based on the determined percussion mode by use of a first parameter set from the at least two parameter sets differs from control of the drive unit based on the determined percussion mode by use of a second parameter set from the at least two parameter sets.
4. The hand-held power tool as claimed in claim 1 , wherein a first parameter set and a second parameter set from the at least two parameter sets differ at least in a percussion frequency.
5. The hand-held power tool as claimed in claim 1 , further comprising:
an operating switch configured to manually control the drive unit; and
an operating-switch position unit operably connected to the operating switch and configured to determine a position of the operating switch and to provide the determined position to the electronics system.
6. The hand-held power tool as claimed in claim 5 , further comprising:
a battery pack,
wherein a battery-pack operating parameter is configured to be provided to the electronics system.
7. The hand-held power tool as claimed in claim 6 , wherein the electronics system is configured to select the selected parameter set from the at least two parameter sets based on at least one of the operating switch position, an instantaneous rotational speed of an electric motor of the drive unit, a weight parameter, and the battery-pack operating parameter.
8. A hand-held power tool comprising:
a drive unit;
a housing in which the drive unit is mounted;

an electronics system configured to:
control at least the drive unit by open-loop or closed-loop control;
automatically select a parameter set from at least two parameter sets;
determine a percussion mode of the hand-held power tool using the selected parameter set from the at least two parameter sets and based on the at least one motion variable; and
control the drive unit based on the determined percussion mode of the hand-held power tool,
wherein the at least two parameter sets are configured such that control of the drive unit based on the determined percussion mode by use of a first parameter set from the at least two parameter sets differs from control of the drive unit based on the determined percussion mode by use of a second parameter set from the at least two parameter sets.
9. A hand-held power tool comprising:
a drive unit;
a housing in which the drive unit is mounted;
