摘要： Method for detecting a first operating state of a handheld power tool, wherein the handheld power tool has an electric motor. In this case, the method comprises the steps of: (S1) determining a signal of an operating variable of the electric motor; (S2) comparing the signal of the operating variable with at least one model signal waveform typical of the state, wherein the model signal waveform typical of the state is assigned to the first operating state; (S3) deciding whether the first operating state is present, wherein the decision at least partially depends on whether the model signal waveform typical of the state is identified in the signal of the operating variable in step S2. Additionally disclosed is a handheld power tool, particularly an impact driver, with an electric motor and a control unit, wherein the control unit is designed to execute a method according to the disclosure.

摘要： A method for operating a hand-held power tool is disclosed, with the hand-held power tool including an electric motor. The method includes step (S1) providing comparative information, having the steps of (S1a) providing at least one model signal waveform, said model signal waveform being assignable to the work progress of the hand-held power tool, and (S1b) providing a threshold of a match. The method further includes step (S2) ascertaining a signal of an operational variable of the electric motor. The method also includes step (S3) analyzing the comparative information and the signal of an operational variable, having the steps of (S3a) comparing the signal of the operational variable with the model signal waveform and ascertaining a match signal from the comparison, and (S3b) ascertaining a match evaluation, said match evaluation being carried out at least partly using the threshold of the match and using the match signal. In addition, the method includes step (S4) detecting the work progress at least partly using the match evaluation ascertained in step S3, said comparative information being provided at least partly on the basis of an automatic evaluation of the match signal. An associated hand-held power tool is also disclosed.

摘要： A method is for operating a hand-held power tool that includes an electric motor. The method includes determining a signal of an operating parameter of the electric motor; determining an application class at least partly on the basis of the signal of the operating parameter; and providing comparative information at least partly on the basis of the application class including (i) providing at least one model-signal form, and (ii) providing a threshold value for correspondence. The model-signal form can be assigned to an established state in the progress of the work performed by the hand-held power tool. The method further includes comparing the signal of the operating parameter with the model-signal form and determining a correspondence evaluation from the comparison. The correspondence evaluation is at least partly based on the threshold value for correspondence.
