Vibration control apparatus, vibration control method, control system, and vibration apparatus

A vibration control method, comprising:

• selecting a target vibration signal that is a target vibration waveform;
• generating a drive signal to be output to a vibration apparatus in order for the vibration apparatus that comes into contact with a vehicle and vibrating the vehicle from outside to vibrate the vehicle with the target vibration signal;
• obtaining a vehicle body vibration signal that is a vibration signal of the vehicle vibrated by the vibration apparatus;
• generating an adjustment vibration signal for making the vehicle body vibration signal coincide with the target vibration signal;
• and
• updating the drive signal on a basis of the adjustment vibration signal so that the vibration apparatus vibrates the vehicle with the target vibration signal.

A control system, comprising:

• a vibration apparatus that comes into contact with a vehicle and vibrates the vehicle from outside;
• and
• a vibration control apparatus including
• a vibration signal selection unit that selects a target vibration signal that is a target vibration waveform, and
• a drive signal generation unit that
• generates a drive signal to be output to a vibration apparatus in order for the vibration apparatus to vibrate the vehicle with the target vibration signal,
• obtains a vehicle body vibration signal that is a vibration signal of the vehicle vibrated by the vibration apparatus,
• generates an adjustment vibration signal for making the vehicle body vibration signal coincide with the target vibration signal, and
• updates the drive signal on a basis of the adjustment vibration signal so that the vibration apparatus vibrates the vehicle with the target vibration signal.
