SUSPENSION CONTROL DEVICE AND SUSPENSION CONTROL METHOD

A suspension control device that is connected to a sensor that acquires information regarding a vehicle or surrounding information of the vehicle, and calculates a suspension control value for controlling a suspension of the vehicle based on the information acquired by the sensor includes: a reached vibration generation unit that generates a reached vibration reaching the vehicle based on the information acquired by the sensor; a sampling processing unit that samples a vibration waveform of the reached vibration by changing a time width for sampling the vibration waveform of the reached vibration according to a frequency of the reached vibration generated by the reached vibration generation unit; and a control value calculation unit that calculates the suspension control value based on a sampling value of the vibration waveform sampled by the sampling processing unit.
