<P>PROBLEM TO BE SOLVED: To realize an opening/closing control device for a vehicle capable of easily correcting the full closing position of an opening/closing body. <P>SOLUTION: This opening/closing control device comprises a rotating sensor 6 detecting the rotation of a motor 3 driving a window 9, a voltage detection circuit 5 detecting the terminal voltage of the motor, and an estimated load calculation part calculating an estimated load (load torque) on the basis of these input signals. When the load torque when the rotation of the opening/closing body is stopped is sufficient to an original cut-off torque when the opening/closing body is fully closed, a CPU 8 corrects the full closing position according to the insufficient torque. When the displacement of the opening/closing body is detected with the counted number of pulses without using an expensive displacement sensor, and the counted number is initialized with the stop detection position when the opening/closing body is drivingly fully closed taken as the full closing position, the opening/closing body can be controllably opened and closed on the basis of the original full closing position by the correction thought the full closing position is displaced if the counted number of pulses is initialized at the stop position before that position due to the low temperature hardening of the weather strip of the power window. <P>COPYRIGHT: (C)2007,JPO&INPIT |
