Title: DEVICE AND METHOD FOR GENERATING A HAPTIC MOMENT AT AN ACTUATOR
Abstract:
The invention relates to a device (1) for generating a haptic moment at an actuator (10), comprising an unbalance motor (2), a sensor for sensing activation of the actuator (10) and a processor (3) for generating an actuation signal for the unbalance motor (2) as a function of signals of the sensor, wherein the processor (3) is embodied in such a way that, when activation of the actuator (10) is sensed, said processor (3) generates a first actuation signal (S1(D)) and generates a second actuation signal (S2(D)), wherein the first actuation signal (S1(D)) is configured in such a way that the unbalance motor (2) is accelerated in a first rotational direction (DR1) without reaching more than two revolutions, and the second actuation signal (S2(D)) is configured in such a way that the unbalance motor (2) is braked without the unbalance motor (2) starting to move in the second rotational direction.
