Abstract
A device may include a piezoelectric actuator and a processor. The piezoelectric actuator is configured to: generate a first electric signal in response to a first user contact associated with the switchpack; and generate a haptic feedback based on a control signal. The processor is configured to: determine, based at least in part on the first electric signal, that the first user contact indicates a first user operation; and generate the control signal based on the first user operation.
Claims20
A switchpack for a vehicle, comprising:
- a piezoelectric actuator configured to:
- generate a first electric signal in response to a first user contact associated with the switchpack;
- and
- generate a haptic feedback based on a control signal;
- and
- a processor configured to:
- determine, based at least in part on the first electric signal, that the first user contact indicates a first user operation, and
- generate the control signal based on the first user operation.
A steering wheel for a vehicle, comprising:
- a steering wheel switch, comprising:
- a sensor configured to:
- generate a first electric signal in response to a first user contact associated with the steering wheel switch;
- and
- generate a haptic feedback based on a control signal;
- and
- a processor configured to:
- determine, based at least in part on the first electric signal, that the first user contact indicates a first user operation;
- and
- generate the control signal based on the first user operation.
A method for calibrating a steering wheel switch of a vehicle, the method comprising:
- setting a scroll wheel to a first discrete angular position;
- pressing the scroll wheel to change the scroll wheel from an unpressed state to a pressed state;
- and
- determining a first 3D magnetic field difference associated with the unpressed state and the pressed state at the first discrete angular position.
