  • Patent number: 12314498
    Abstract: An input apparatus includes an operating unit on which an input operation is performed by an operator, a detecting unit configured to detect the input operation performed on the operating unit, an actuator configured to impart vibration to the operating unit, and a control unit configured to supply a drive signal to the actuator according to a result of detection performed by the detecting unit. The control unit supplies, as the drive signal, a single pulse signal including a triangular wave or a sine wave and having a signal waveform in which a rising interval and a falling interval are asymmetric about a peak position to the actuator.

  • Patent number: 10930445
    Abstract: A rotary operating device includes an operation part that is rotatable according to an operation by an operator, a rotation angle sensor that detects a rotation angle of the operation part, a torque applier that applies application torque to the operation part along a rotation direction of the operation part, a frictional force applier that applies a frictional force to the operation part, and a processor programmed to change the application torque and the frictional force according to the rotation angle.

  • Patent number: 10095364
    Abstract: An in-vehicle input device includes a touch panel including a lower electrode, an upper electrode, and a spacer, and is capable of detecting a capacitance between the lower electrode and the upper electrode. The device has an operation surface located above the upper electrode. The operation surface includes a plurality of operation areas. The spacer has a plurality of openings that coincide with the operation areas in plan view. The device further includes a suppression layer that is disposed between the operation surface and the upper electrode or disposed on an upper surface of the operation surface. The suppression layer eliminates or reduces formation of a capacitance between the upper electrode and an operator. The device detects an input operation based on a change in distance between the lower electrode and the upper electrode in response to pressing any of the operation areas by the operator.
