Method for detecting a slip clutch release event, and power tool

A method for detecting whether a slip clutch release event has taken place in a power tool (1), the power tool (1) comprising:

• a motor (3) as a drive for the power tool (1);
• a control device (4);
• a gear device (5);
• a first sensor (10) for sensing a first speed of the gear device (5);
• a second sensor (20) for sensing a second speed of the motor (3);
• a third sensor (30) for sensing a current value;
• and
• a slip clutch (12);
• and comprising the steps of:
• a) determining the first speed of the gear device (5) by the first sensor (10);
• b) determining the second speed of the motor (3) by the second sensor (20);
• c) determining the current value by the third sensor (30);
• d) determining a state of the power tool (1) by using the first and second speeds and the current value;
• e) determining a state of the gear device (5) in dependence on the current value by the control device;
• f) ascertaining a state of activity of the slip clutch (12) in dependence on the first and second speeds by the control device;
• and
• g) ascertaining by the control device by a combination of the state of the gear device (5) and the state of activity of the slip clutch (12) whether the slip clutch release event has taken place.
