Embodiment Construction

[0024] The device 1 for generating a tactile moment at an actuator 10 comprises an unbalanced motor 2 , a processor 3 , a driver 4 and a pressure sensor 5 . The pressure sensor 5 is connected to the processor 3 and evaluates whether the actuator 10 is actuated or pressed. For this, it is checked, for example, whether the pressure signal of the pressure sensor 5 exceeds a threshold value. In this respect, the processor 3 generates a first actuation signal S1 (D) and a second actuation signal S2 (D), which are amplified by the driver 4 and supplied to the unbalanced motor 2 . The actuation signals S1(D), S2(D) are here PWM signals, preferably 100% PWM signals. The % value of the PWM signal can be adjusted here, at what speed the unbalanced motor 2 runs. The higher the PWM value, the higher the speed or acceleration into the direction of rotation. By means of the control input S, the actuation signal at the drive 4 can be reversed so that the direction of rotation of the unbal...

Abstract

The invention relates to a device (1) for generating a tactile moment at an actuator (10), comprising an unbalanced motor (2), a sensor for acquiring the manipulation of the actuator (10) and a The signal of the sensor generates a processor (3) for the actuation signal of the unbalanced motor (2), wherein the processor (3) is designed in such a way that it generates a first actuation signal when the actuator (10) is actuated (S1(D)) and the second actuation signal (S2(D)), wherein the first actuation signal (S1(D)) is designed such that the unbalanced motor (2) does not achieve more than two revolutions Acceleration into the first direction of rotation (DR1), wherein the second actuation signal (S2(D)) is designed such that the unbalanced motor (2) is not activated in the second direction of rotation without the unbalanced motor (2) down is braked.

Description

technical field [0001] The invention relates to a device and a method for generating a haptic moment at an actuator. Background technique [0002] Increasingly, actuators such as mechanical switches are replaced by touch-sensitive switch surfaces. In this case, however, tactile moments are lacking as feedback for the user. This can lead to user uncertainty as to whether the manipulation of the actuator was successful. [0003] Vibration devices are known in various embodiments for warning the user. A very compact and inexpensive design of an oscillating device is an unbalanced motor, which is designed, for example, as a stepper motor. Such a vibration device is described, for example, in DE 10 2013 001 323 B3. [0004] Vibration as a tactile torque on the actuator is generally undesirable, however, since this does not correspond to the desired feedback. Contents of the invention [0005] The technical problem underlying the invention is to create a device for generati...
