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.
