Abstract
A controller for controlling an actuator device which is installed on a vehicle and operated by a motor. The controller includes: a motor control portion operable to control the motor on the basis of a target value; and a target-value determining portion operable to determine the target value on the basis of a wave intensity characteristic. The wave intensity characteristic is represented by a relationship between (A) a propagated wave intensity indicative of an intensity of a wave which is generated as a result of activation of the actuator device and which is propagated to occupant of the vehicle, and (B) an output index indicative of an amount of an output of the motor. Also disclosed is a wave-intensity-characteristic obtainer for obtaining the wave intensity characteristic by measuring the intensity of the wave.
