The disclosure relates to a hand-held power tool comprising a percussion mechanism, especially a rotary hammer and/or percussion hammer. According to the disclosure, at least one sensor unit comprising at least sensor for at least one mechanical measurement variable is provided for detecting at least one percussion parameter.

Hand-held power tool

Percussion unit, especially for a rotary hammer and/or percussion hammer, comprising a control unit which is designed for controlling a pneumatic percussion mechanism. According to the disclosure, the control unit comprises at least one load estimation device.

Percussion unit

Percussion unit, especially for a rotary hammer and/or percussion hammer, comprising a control unit which is designed for open-loop and/or closed loop control of a pneumatic percussion mechanism, and at least one operating condition sensor unit. According to the disclosure, the control unit is designed to detect at least one percussion mechanism parameter depending on measurement values of the operating condition sensor unit.

A percussion unit for a rotary hammer and/or percussion hammer includes a control unit that is configured for open-loop and/or closed loop control of a pneumatic percussion mechanism. In at least one operating state in which the control unit changes from an idle mode to a percussion mode, the control unit is configured to adjust at least one operating parameter temporarily to a starting value.

The disclosure relates to an electric tool, particularly a hand-held power tool, comprising a control unit which has control software with control parameters, and is provided for the purpose of controlling a drive unit. According to the disclosure, said electric tool comprises an interface unit that is provided to fundamentally update and/or modify the control software and/or the control parameters.
