Control device, control method, and recording medium

A control method for controlling vibrations generated by a vibration device mounted on a driving manipulation element of a vehicle, the control method comprising:

• decomposing, by a computer, vibrations reproduced at a predetermined point on the driving manipulation element into frequency components;
• performing, by the computer, a filtering process corresponding to at least one of a vibration characteristic of the vibration device and a vibration transmission characteristic of the driving manipulation element from the vibration device to the predetermined point on the frequency components into which the vibrations are decomposed;
• synthesizing, by the computer, the frequency components on which the filtering process has been performed;
• and
• causing, by the computer, the vibration device to generate vibrations corresponding to the synthesized frequency components.

A computer-readable non-transitory recording medium recording a program for causing a computer to

• decompose vibrations reproduced at a predetermined point on a driving manipulation element of a vehicle into frequency components,
• perform a filtering process corresponding to at least one of a vibration characteristic of a vibration device mounted on the driving manipulation element and a vibration transmission characteristic of the driving manipulation element from the vibration device to the predetermined point on the frequency components into which the vibrations are decomposed,
• synthesize the frequency components on which the filtering process has been performed, and
• cause the vibration device to generate vibrations corresponding to the synthesized frequency components.
