Power window apparatus for vehicle
First Claim
1. A power window apparatus for a vehicle, comprising:
- a drive motor for raising and lowering a window glass;
an operation switch comprising a raising contact which outputs a window raising command when the raising contact is set at on-state and a lowering contact which outputs a window lowering command when the lowering contact is set at on-state; and
a controller coupled to the drive motor and the operation switch, the controller being arranged, to execute a manual operation during a time period from a start moment at which the operation switch starts outputting one of the window raising and lowering commands to a first moment at which a first predetermined time period elapses from the start moment, to execute an automatic operation during a time period from the first moment to a second moment at which a second predetermined time period elapses from the start moment, and to execute the manual operation from the second moment.

Abstract
A power window apparatus for a vehicle is comprised of an operation switch which includes a raising contact for outputting a window raising command when set at on-state and a lowering contact for outputting a window lowering command when set at on-state, and a controller which is arranged to execute a manual operation during a time period from a start moment at which the operation switch starts outputting one of the window raising and lowering commands to a first moment at which a first predetermined time period elapses from the start moment, to execute an automatic operation during a time period from the first moment to a second moment at which a second predetermined time period elapses from the start moment, and to execute the manual operation from the second moment.

8. A method of controlling a drive motor for raising and lowering a window glass, comprising:
-
executing a manual operation during a time period from a start moment at which an operation switch outputs one of a window raising and lowering commands to a first moment at which a first predetermined time period has elapsed from the start moment;
executing an automatic operation during a time period from the first moment to a second moment at which a second predetermined time period has elapsed from the start moment, and executing the manual operation from the second moment.

9. A power window apparatus for vehicle, comprising:
-
driving means for raising and lowering a window glass;
switch means for outputting one of a window closing command and a window opening command according to an intent of a vehicle occupant;
first execution means for executing a manual operation during a time period from a start moment at which the operation switch outputs one of the window raising and lowering commands to a first moment at which a first predetermined time period has elapsed from the start moment, second execution means for executing an automatic operation during a time period from the first moment to a second moment at which a second predetermined time period has elapsed from the start moment, and third execution means for executing the manual operation from the second moment.

10. A power window apparatus for a vehicle, comprising:
-
a drive motor for raising and lowering a window glass;
an operation switch outputting a window closing command when a vehicle occupant turns on the operation switch;
a rotation detector attached to the drive motor and detecting a rotation speed of the drive motor; and
a controller coupled to the drive motor, the operation switch and the rotation detector, the controller being arranged, to operate the drive motor so as to raise the window glass from a start moment at which the operation switch outputs the window raising command, to count an elapsed time from the start moment, to calculate a load applied to the drive motor on the basis of the rotation speed of the drive motor, to stop operating the drive motor when the load is greater than a predetermined load, to operate the drive motor so as to lower the window glass when the operation switch stops outputting the window raising command before the elapsed time reaches a predetermined time period and when the load is greater than the predetermined load, to restart the operation of the drive motor to raise the window glass from a moment at which the elapsed time reaches the predetermined time period and when the operation switch continues outputting the window raising signal. - View Dependent Claims (11)
