Abstract
A control system and method for operating an automobile window to provide anti-trap protection in an AUTO UP mode, wherein a switch assembly communicates switch signals representative of operator commands by disposition in distinct positions. A sensor that detects when an object is trapped between the window and the frame, and transmits an anti-trap signal representative thereof. A logic circuit receives the switch signals and the anti-trap signal and controls the drive assembly for the window in response thereto. The switch assembly includes a switch to override the anti-trap sensor for closing the window even when an obstruction is sensed during the closing operation.
Claims15
A control system for an automobile window including anti-trap protection in an UP mode, comprising:
- a motorized drive assembly for drive assembly for driving the automobile window between open and closed;
- a sensor disposed to detect when an object is present between the automobile window and an automobile window frame and to transmit an anti-trap signal representative thereof, wherein the sensor is positioned adjacent a seal of the window frame;
- a switch assembly for communicating switch signals representative of commands from an operator by disposition of the switch assembly in selected distinct modes comprising positions or time intervals;
- and,
- a logic circuit disposed to receive the switch signals and the anti-trap signal and control the drive assembly in response thereto, wherein the switch assembly comprises at least a first switch moveable to said distinct modes comprising an OFF mode, a MANUAL DOWN mode, an AUTO DOWN mode, an AUTO UP mode with the anti-trap protection enabled, and a MANUAL UP mode with the anti-trap protection disabled.
A control system for an automobile window including anti-trap protection in an UP mode, comprising:
- a motorized drive assembly for drive assembly for driving the automobile window between open and closed;
- a sensor disposed to detect when an object is present between the automobile window and an automobile window frame and to transmit an anti-trap signal representative thereof;
- a switch assembly for communicating switch signals representative of commands from an operator by disposition of the switch assembly in selected distinct modes comprising positions or time intervals;
- and,
- a logic circuit disposed to receive the switch signals and the anti-trap signal and control the drive assembly in response thereto, wherein the switch assembly comprises a switch moveable to said distinct modes, said distinct modes comprising an OFF mode, a MANUAL DOWN mode, an AUTO DOWN mode, an AUTO UP mode with the anti-trap protection enabled, a MANUAL UP mode with the anti-trap protection enabled and a MANUAL UP mode with the anti-trap protection disabled.
A method of operating a switch assembly for an automobile window to implement an override of an anti-trap system when closing the window, the method comprising steps of:
- disposing the switch assembly to have a plurality of distinct positions representative to an operator of distinct window operations comprising an OFF mode, a first UP mode with anti-trap enabled and a second UP mode with anti-trap disabled,
- first moving the switch from the OFF position to the first UP position to initiate closing of the window, and,
- second moving the switch from the first UP position to the second UP position to continue closing the window wherein the anti-trap system is disabled.
