<P>PROBLEM TO BE SOLVED: To provide a control unit of an opening and closing body for a vehicle, which can detect pinching at an early stage, and which enables a detection load for the determination of the pinching to be set small. <P>SOLUTION: In this control unit (power window drive unit) of the opening and closing body for the vehicle, an estimated load computing portion 13 computes an estimated load fo of a motor from the rotational speed, rotational acceleration and drive voltage of the motor. A vibration load computing portion 15 computes a vibration load fp of the motor, from a detected signal of an acceleration sensor attached to the vehicle (e.g. a control board of the motor and an ECU). Additionally, a vibration elimination load computing portion 17 corrects the computed value of the estimated load fo, computed by the estimated load computing portion 13, by a computed value of the vibration load fp computed by the vibration load computing portion 15. As a result, the vibration load fp due to vibration disturbance is excluded from the estimated load fo of the motor. <P>COPYRIGHT: (C)2011,JPO&INPIT |
