Abstract

Motor vehicle electric window regulator antilock control function enabling a motor vehicle operator to belatedly close any vehicle windows inadvertently remaining open subsequent to usual ignition key withdrawal and electrical system lockup of the motor vehicle without necessitating the inconvenient reinsertion of the ignition key to reactivate the electric window regulator system. Post-exit closure of windows may also be provided whereby any inadvertently left-open windows may be closed after the operator has exited from and even locked-up the vehicle. In another setting in a vehicle using electric door locks, lock-up is denied if any windows are left open. Still another arrangement brings about automatic window roll-up whenever certain acts occur, such as when the ignition key is turned-off, the driver'"'"'s door is opened, or electric locks are set to lock the vehicle.

Claims

1. An accessory control method extending at least temporary electric window regulator operability in a motor vehicle for a limited extent of time immediately following ignition system switch lockup and usual accessory electrical system disablement, comprising steps of:

initiating an onset of an elapse of the limited extent of time in immediate response to the ignition system switch lockup;

deferring disablement of a portion of the accessory electrical system which determines said electric window regulator operability for the limited extent of time;

thereby maintaining operability of at least a driver or operator accessible set of electric window regulator controls for the limited extent of time and enabling an inadvertently left-open window to be conveniently closed by the operator of the motor vehicle without a necessitous unlocking of the ignition system switch.

2. The accessory control method of claim 1 wherein the motor vehicle may include an electric door lock system and comprise further steps of:

enabling the electric door lock system to LOCK and UNLOCK utilizing an operator controlled and momentarily activated selectable mode door-lock switch having at least LOCK and UNLOCK finger activated actuator buttons;

staging at least one of the door lock switch said LOCK and UNLOCK said actuator buttons to express at least two levels of operation;

incrementing the staged said actuator button to a first level which is partially depressed, and

incrementing the staged said actuator button to a second level which is fully depressed;

whereby, the first level of the staged said actuator button depression enables actuation of the electric door lock system, and the second level of the staged said actuator button depression determines said electric window regulator operability for the limited extent of time and enables at least one-way said window regulator operability by the operator.

3. The accessory control method of claim 1 wherein the motor vehicle may include an electric door lock system and comprise further steps of:

sensing window position set by the electric window regulator; and

,

disabling electric lock-up of at least a driver position said electric door lock system whenever the set window position is sensed to be other than about closed.

inserting a key into a tumbler portion of an exterior lockset device ordinarily utilized for manual door lock-up subsequent to an operator'"'"'s exit from the motor vehicle,

maintaining the key and the tumbler in a designated relational position for a prolonged period of time; and

,

enabling the electric window regulator operation to produce at least a window closure when the prolonged period of time exceeds a predetermined time interval of several seconds duration.

7. An electric window control method for at least temporarily enabling a predetermined extent of electric window regulator operation subsequent to ignition system lock-up and a disablement of a substantial portion of a motor vehicle'"'"'s accessory electrical circuits and therefor comprising steps of:

opening at least one of the fully closed windows to a limited extent preferably less than about one inch, thereby permitting partial ventilation of the motor vehicle.

10. The electric window control method of claim 7 comprising a further step of:

predetermining the electric window regulator to include an automatic closure mode which immediately closes otherwise inadvertently left-open windows of the motor vehicle during the first period of time.

11. The electric window control method of claim 7 which, during a period of said maintained operability of the accessory electrical circuits and subsequent to an operator'"'"'s exiting from and locking the motor vehicle'"'"'s access door, comprises further steps of:

maintaining the key and the tumbler in a predetermined position for at least a second period of time of less time duration than the first period of time; and

,

enabling the electric window regulator to produce at least closure control of inadvertently left-open windows following an elapse of the second period of time.

12.
