Force-applying input device
First Claim
Patent Images
1. A force-applying input device comprising:
- an operating unit;
a position sensor which detects an operational state of the operating unit and outputs a position signal;
an actuator which applies an external force to the operating unit; and
a controller which outputs an actuator drive signal on the basis of the position signal to control the actuator, wherein the controller calculates a current position and a current speed of the operating unit on the basis of the position signal and determines a first component of the actuator drive signal, the first component corresponding to the current position, by multiplying a sum of the current position and a product of the current speed and a coefficient by an elastic modulus.

Abstract
A force-applying input device has a controller which calculates a torque component of an actuator drive signal corresponding to a current position by multiplying the sum of the current position and the product of a current speed and a coefficient by an elastic modulus. In addition, the controller also calculates a torque component of the actuator drive signal corresponding to the current speed by multiplying the current speed by a coefficient of viscous friction.
