    The sensor unit 16 includes at least one first sensor element 20, which is provided for detecting the at least one operating and / or environmental parameter of the handheld power tool device 10. The first sensor element 20 is provided for detecting a spatial position of the hammer mechanism unit 12 of the handheld power tool device 10.

The first sensor element 20 is formed by an acceleration sensor. The first sensor element 20 is formed by a triaxial acceleration sensor. However, it is also conceivable that the first sensor element 20 is formed by a MEMS sensor. Alternatively or additionally, the sensor unit 16 for detecting the angular acceleration may also comprise at least one rotation rate sensor.
    The sensor unit 16 includes at least one further sensor element 22, which is provided for detecting at least one further operating and / or environmental parameter of the handheld power tool device 10. The further sensor element 22 of the sensor unit 16 is provided to detect an environmental parameter of the percussion unit 12. The further sensor element 22 of the sensor unit 16 is provided for detecting an ambient air pressure of the percussion unit 12. The further sensor element 22 of the sensor unit 16 is formed by a pressure sensor.
    The hand-held power tool device 10 comprises the hammer mechanism unit 12, a shock detection unit 32 which is provided to detect a translational drive state of the insertion tool 14 by the impact mechanism unit 12, and a blockage detection unit 34 which is provided for angular acceleration of the hand tool machine 36 about the machining axis 30 of FIG Insert tool 14 and the percussion unit 12 to capture. The impact detection unit 32 is provided to detect a linear acceleration that is parallel to a machining axis 30 of the insertion tool 14. The impact detection unit 32 includes a sensor element 20, which is provided for detecting the translational drive state of the insertion tool 14. The sensor element 20 is provided for detecting the linear acceleration in the axial direction 50 in the hammer operating state and in the hammering operating state. The blockage recognition unit 34 forms an anti-rotation system. The blockage recognition unit 34 comprises a sensor element 20, which is provided for the detection of the angular acceleration. The impact detection unit 32 and the blockage detection unit 34 of the handheld power tool device 10 are formed at least partially in one piece. The impact detection unit 32 and the blockage detection unit 34 are at least partially formed integrally with the sensor unit 16. The impact detection unit 32 comprises the first sensor element 20 of the sensor unit 16. The blockage detection unit 34 likewise comprises the first sensor element 20 of the sensor unit 16.
    The hand-held power tool device 10 further has a control and / or regulating unit 18, which is provided for controlling and / or regulating the impact mechanism unit 12 as a function of the operating and / or environmental parameter detected by the sensor unit 16. The control and / or regulating unit 18 is provided for controlling and / or regulating the percussion unit 12 as a function of the spatial position of the percussion unit 12, the linear acceleration and / or the angular acceleration. The control and / or regulating unit 18 is designed as a control unit 52 and is provided for controlling the striking mechanism unit 12 via the drive unit 46. Alternatively or additionally, it is also conceivable that the control and / or regulating unit 18 is designed as a control unit and is provided for a regulation of the hammer mechanism unit 12. The control unit 52 is provided for controlling the percussion unit 12 in dependence on the operating parameters detected by the first sensor element 20 of the sensor unit 16. The control unit 52 is also provided for controlling the percussion unit 12 as a function of the environmental parameter detected by the further sensor element 22 of the sensor unit 16. Alternatively or additionally, it is also conceivable for the control unit 52 to be provided for manual control, for example by means of an operator-actuatable adjustment knob or dial.
    The control unit 52 comprises a microcontroller. The control unit 52 is electronically coupled to the sensor unit 16. The parameters detected by the sensor elements 20, 22 of the sensor unit 16 are forwarded to the control unit 52.
    The control unit 52 evaluates the parameters detected by the sensor unit 16, compares the parameters detected by the sensor unit 16 with predetermined limit values stored in the control unit 52, and controls the percussion unit 12 according to a control algorithm stored in the control unit 52. If the detected parameters reach or exceed a predetermined maximum value and / or if the detected parameters reach or fall below a predefined minimum value, the control unit 52 changes an output control parameter which is forwarded to the drive unit 46 or to the percussion unit 12.
    The weight force acting on the movably mounted components of the percussion unit 12, affects the operation of the percussion unit 12. In the space position in which the machining axis 30 of the insertion tool 14 is arranged parallel to the direction of the weight and a transmission direction of the pulse from the striker to the insert tool 14 in the hammer operating state or in the Schlagbohrbetriebszustand the effective direction of the gravitational force, the moving components of the percussion unit 12 are accelerated against the weight. On the other hand, the movable members of the percussion mechanism unit 12 in the space position in which the processing axis 30 of the insertion tool 14 parallel to the effective direction of the weight and the transmission direction of the pulse from the striker to the insert tool 14 in the hammer operating state or in the Schlagbohrbetriebszustand the effective direction of the weight force rectified is additionally accelerated by the weight. In the spatial position in which the machining axis 30 of the insert tool 14 is arranged perpendicular to the effective direction of the weight force, the weight force affects the movable components of the percussion unit 12 comparatively only insignificantly. The intermediate spatial positions in which the machining axis 30 of the insertion tool 14 and the effective direction of the weight include an angle which is between 0 0 and 90 °, the output control parameters must be adjusted by the control unit 52 accordingly. The output control parameters are formed by a speed or torque of the drive unit 46 or other parameters that appear reasonable to those skilled in the art. As a result, an optimal processing result can be achieved in any spatial position.
    The control unit 52 is further provided for a shutdown of the drive unit 46 and thus the percussion unit 12 in the Schlagbohrbetriebszustand or in Bohrbetriebszustand when the detected by the blocking detection unit 34 and the first sensor element 20 of the sensor unit 16 angular acceleration reaches or exceeds a predetermined maximum value. High angular acceleration about the machining axis 30 of the insert tool 14 in the hammering operating state or in the drilling operating state may indicate an uncontrolled stalling event in which the deployment tool 14 is blocked and the rotational motion is transmitted to the handheld power tool 36. By switching off the drive unit 46 and thus the percussion unit 12 in this uncontrolled blocking case, an advantageously high operator safety can be achieved. The first sensor element 20, which is formed by the three-axis acceleration sensor, detects the angular acceleration over two of the three measuring axes. The three measuring axes of the three-axis acceleration sensor are each arranged perpendicular to each other. The two measuring axes of the three-axis acceleration sensor, which are provided for detecting the angular acceleration about the machining axis 30 of the insert tool 14, are arranged perpendicular to the machining axis 30 of the insert tool 14.
    The impact detection unit 32 or the first sensor element 20 of the sensor unit 16, which is formed by the three-axis acceleration sensor, detects the linear acceleration over the measuring axis of the three-axis acceleration sensor which is parallel to the machining axis 30 of the insert tool 14 and perpendicular to the other two measuring axes of the three-axis acceleration sensor , which are arranged to detect the angular acceleration about the machining axis 30 of the insert tool 14 is arranged. The three-axis acceleration sensor records the spatial position with all three measuring axes.
    The handheld power tool device 10 also has an output unit 24, which is provided for a perceptible by the operator of the power tool 36 output of the at least one operating and / or environmental parameter. The output unit 24 is electronically coupled to the control unit 52 and thus also to the sensor unit 16. The output unit 24 is provided for outputting the spatial position detected by the first sensor element 20 of the sensor unit 16. The output unit 24 is provided for a visual output of the detected spatial position. Alternatively or additionally, an acoustic, a haptic and / or another output that appears appropriate to a person skilled in the art is also conceivable. In addition, it is also conceivable that the output unit 24 is provided for outputting the detected angular acceleration, the detected linear acceleration and / or another parameter which appears expedient to a person skilled in the art. The output unit 24 includes a display. However, it is also conceivable that the output unit 24 comprises, alternatively or additionally, individually arranged LEDs, a loudspeaker or other output elements which appear expedient to a person skilled in the art. The output unit 24 is embedded in the housing 48 of the power tool 36. The output unit 24 can be provided to assist an operator by outputting the current spatial position in a targeted orientation of the power tool 36, such as in a horizontal or in a vertical position. For example, on the display of the dispensing unit 24, arrows may be displayed which indicate to an operator in which direction he must turn or tilt the hand tool 36 about the horizontal or vertical position of the machining axis 30 of the insert tool 14 or otherwise useful to one skilled in the art to reach the apparent position. Thus, by means of the sensor unit 16, the control unit 52 and the output unit 24, a vertical and / or horizontal drilling function can be achieved.
    The handheld power tool device 10 further has an interface unit 26, which is provided for exchanging an operating and / or environmental parameter data record with an external information unit 28. The external information unit 28 can be coupled to the handheld power tool device 10 of the handheld power tool 36 via the interface unit 26. In a coupled state of the handheld power tool device 10 of the handheld power tool 36 with the external information unit 28, the operating and / or environmental parameter data set comprising, for example, information on an environment of the handheld power tool 36 having the handheld power tool 10, from the external information unit 28 to the control unit 52 of the power tool device 10 are passed. The external information unit 28 is formed by a smartphone. However, other embodiments of the external information unit 28 which appear sensible to a person skilled in the art are also conceivable. The external information unit 28 is connected via a cable, not shown, in particular via a data cable, with the hand tool device 10 of the power tool 36. The interface unit 26 has a connector element, not shown in detail, in particular a USB slot, which is embedded in the housing 48 of the power tool 36. However, it is also conceivable that the external information unit 28, in particular non-contact, a radio signal such as Bluetooth, WLAN, IR or another, as a skilled person he seems useful technology with the hand tool device 10 of the power tool 36 is connected. An operator may, for example, hold his smartphone forming the external information unit 28 against an inclined wall surface such as a roof slope to be worked with the portable power tool 36 so as to detect an inclination of the wall surface. For this purpose, the external information unit 28 may have an app or another program. The detected inclination of the wall surface to be processed can then or at the same time be forwarded via the interface unit 26 to the handheld power tool device 10 of the hand tool 36, where the control unit 52 their output control parameters, especially for the vertical and / or horizontal drilling function, on this detected inclination of the wall surface to be processed adapts.
