MOTOR CONTROL DEVICE AND SEAT CONTROL DEVICE FOR VEHICLE
First Claim
1. A motor control device comprising:
- an acceleration portion for increasing a target number of rotations of a motor every predetermined calculation cycle until the target number of rotations of the motor reaches an upper limit number of rotations, which is set on the basis of a reached position of a driven object from a reference position, the driven object being driven by the motor so that a position of the driven object is changed;
a deceleration portion for decreasing the target number of rotations of the motor every calculation cycle after the target number of rotations reaches the upper limit number of rotations; and
a main control portion for controlling a drive of the motor on the basis of the target number of rotations.

Abstract
A motor control device includes an acceleration portion for increasing a target number of rotations of a motor every predetermined calculation cycle until the target number of rotations of the motor reaches an upper limit number of rotations, which is set on the basis of a reached position of a driven object from a reference position, the driven object is driven by the motor so that a position of the driven object is changed, a deceleration portion for decreasing the target number of rotations of the motor every calculation cycle after the target number of rotations reaches the upper limit number of rotations, and a main control portion for controlling a drive of the motor on the basis of the target number of rotations.

14. A motor control device comprising:
-
an acceleration portion for increasing a target number of rotations of a motor every predetermined calculation cycle until the target number of rotations of the motor reaches an upper limit number of rotations, which is set on the basis of a reached position of a driven object from a reference position, the driven object is driven by the motor so that a position of the driven object is changed; a deceleration portion for decreasing the target number of rotations of the motor every calculation cycle after the target number of rotations reaches the upper limit number of rotations; and a main control portion for driving and controlling the motor on the basis of the target number of rotations, wherein the upper limit number of rotations is set as a value, which decreases as a displacement amount of the driven object from the reference position increases and includes a final steady number of rotations as a minimum value, by which the motor is rotated in a constant speed, and the deceleration portion decreases the target number of rotations on the basis of the upper limit number of rotations.
