Title:
POWER WINDOW DEVICE
Document Type and Number:
Japanese Patent JP3917803
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power window device with a less erroneous action by certainly detecting a clamping-in during the time until a stable action is carried out from the time of motor activation starting.
SOLUTION: The power window device is provided with a pulse generator 15 for generating a repeat pulse corresponding to a rotation of a motor 11; and a control part 14 for judging a clamping-in. The control part 14 is adjusted to a characteristic at the time of activation of the power window device to divide it to three periods, i.e., a first period until a window starts to ascend/ descend; a second period until a constant speed action is carried out; and a third period after the second period. The control part 14 compares one period immediately before the repeat pulse with a subsequent half period at the first and second periods and compares a half period immediately before with a subsequent half period at the third period to judge the clamping-in.
