Patent ID: 7148648

Claim:
A controller for controlling an actuator device which is installed on a vehicle and operated by a motor, said controller comprising: 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 said target value on the basis of at least one wave-intensity characteristic, wherein each of said at least one 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, and wherein said target-value determining portion sets said target value at a value corresponding to a wave-intensity-bottom-value establishing output value in said output index which establishes a bottom value in said propagated wave intensity.
