Method for Determining a Remaining Service Life of a Hand-Held Power Tool as well as Hand-Held Power Tool

Abstract

A method for determining a remaining service life of a hand-held power tool includes, in an operating mode detection step, detecting an operating mode of the hand-held power tool by an alignment of operating data of the hand-held power tool with a comparative value table stored on the hand-held power tool and/or by a switch position detection function of an operating mode selection switch. In a computing step, the remaining service life of the hand-held power tool is calculated via at least the operating mode and its operating time and output to a user of the hand-held power tool in an outputting step.

Description

Claims

1. A method for determining a remaining service life of a hand-held power tool, the method comprising: detecting an operating mode of the hand-held power tool based on an alignment of operating data of the hand-held power tool with a comparative value table stored on the hand-held power tool and/or based on a switch position detection function of an operating mode selection switch;calculating the remaining service life of the hand-held power tool via at least the detected operating mode and an operating time; andoutputting the remaining service life to a user of the hand-held power tool.

2. The method according to claim 1, wherein: the detecting of the operating mode, the calculating of the remaining service life, and the outputting of the remaining service life are performed at each power-on of the hand-held power tool;the method further comprises storing all of the operating data, detected operating modes, and/or the operating times in a memory unit of the hand-held power tool.

3. The method according to claim 1, further comprising: detecting the operating data of the hand-held power tool.

4. The method according to claim 1, further comprising: verifying the switch position of the on/off switch.

5. The method according to claim 1, further comprising: classifying an average and a slope of a current value of ongoing operation of the hand-held power tool.

6. The method according to claim 1, further comprising: classifying an average and a slope of an acceleration value of ongoing operation of the hand-held power tool.

7. The method according to claim 1, further comprising: classifying an average and a slope of a speed value of ongoing operation of the hand-held power tool.

8. The method according to claim 1, further comprising: creating the comparative value table based on an operating mode measurement.

9. The method according to claim 1, further comprising: updating the comparative value table at a regular time interval.

10. The method according to claim 1, wherein, the outputting of the remaining service life further comprises displaying feedback regarding at least the remaining service life, the operating modes, and the operating times to the user via at least one of a human-machine interface and wireless transmission to a terminal device.

11. A hand-held power tool comprising: at least one electronic apparatus comprising: a memory unit;an evaluation unit; anda sensor unit; anda human-machine interface configured to: detect an operating mode of the hand-held power tool based on an alignment of operating data of the hand-held power tool with a comparative value table stored on the hand-held power tool and/or based on a switch position detection function of an operating mode selection switch;calculate the remaining service life of the hand-held power tool via at least the detected operating mode and an operating time; andoutput the remaining service life to a user of the hand-held power tool.

12. The method according to claim 2, wherein the memory unit is a flash drive.

13. The method according to claim 3, wherein the detecting of the operating data further comprises detecting, as the operating data, a switch position of an on/off switch and/or at least a current, acceleration, or speed value of ongoing operation of the hand-held power tool.

14. The method according to claim 8, wherein the creating of the comparative value table is performed prior to the production of the hand-held power tool and during a development phase.
