Abstract

A capacitive switch assembly for controlling power windows of an automotive vehicle has a plurality of window select capacitive sensors with a respective window select capacitive sensor for selecting a respective power window to be opened or closed. The capacitive switch assembly also includes a capacitive actuator including gesture responsive capacitive sensors responsive to an open gesture and a close gesture made by a user with a finger on a gesture pad of the capacitive actuator. The gesture responsive capacitive sensors are located at locations on the gesture pad so that the open and close gestures mimic the way in which a user moves an actuator of a mechanical switch to open and close a window. The capacitive switch assembly may include a hot button that enables and disables the power windows.

Claims

1. A capacitive switch assembly for controlling power windows of an automotive vehicle, comprising

a plurality of window select capacitive sensors with a respective window select capacitive sensor for selecting a respective power window to be opened or closed;

and

a capacitive actuator including gesture responsive capacitive sensors responsive to an open gesture and a close gesture made by a user with a finger on a gesture pad of the capacitive actuator, the gesture responsive capacitive sensors located at locations on the gesture pad so that the open gesture is a mimic open gesture that mimics the way in which a user moves a mechanical switch to open a window and the close gesture is a mimic close gesture that mimics the way in which a user moves a mechanical switch to close a window;

a controller responsive to the window select capacitive sensors and the gesture responsive capacitive sensors and actuating the selected power window to open that power window in response to the gesture being an open gesture and to close that power window in response to the gesture being a close gesture; and

a hot button wherein the controller is responsive to each actuation of the hot button to toggle between an enable and a disable state wherein when in the disable state, the controller disables actuation of the power windows in response to a signal from any of the gesture responsive capacitive sensors.

2. The capacitive switch assembly of claim 1 wherein the gesture responsive capacitive sensors include window open capacitive sensors and window close capacitive sensors.

3. The capacitive switch assembly of claim 2 wherein the gesture pad includes a recess in which the open and close gestures are made.

4. The capacitive switch assembly of claim 1 wherein the controller is responsive to an express open or close gesture to fully open or close the selected power window regardless of whether the user holds the gesture on the gesture pad at the completion of the gesture and responds to a tap of the user'"'"'s finger on the gesture pad by stopping movement of the selected power window, and is responsive to a manual open or close gesture by actuating the power window to open or close it as long as the user is holding the finger making the gesture on the finger pad at the completion of the gesture and stops actuation of the selected power window in response to the user releasing the gesture by removing the finger making the gesture from the gesture pad.

5. The capacitive switch assembly of claim 1 wherein the hot button is spaced from the window select capacitive sensors and capacitive actuator at least 60 mm.
