Embodiment Construction
[0019] Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in application to the details of construction and the arrangement of components set forth in the following description or shown in the following drawings. The invention has other embodiments and can be practiced or carried out in various ways.
[0020] figure 1 An interior component or trim panel 20 is shown installed within a vehicle (not shown). In the illustrated construction, the trim panel 20 is an armrest adjacent to one or more seating positions within the vehicle. However, the interior panel 20 can also be replaced with other structural forms. The trim panel 20 has an integral pressure sensing interface 24 ( image 3 ), the pressure sensing interface 24 will be described in further detail below.
[0021] The interior trim panel 20 includes a substrate 28 and a covering layer or covering 32 . Covering layer 32 may cover all or a portion ...

Abstract
A vehicle control system for receiving touch-based inputs for controlling one or more vehicle systems or components. A pressure sensing interface includes first and second non-conductive layers and an intermediate layer that is interposed between the first and second non-conductive layers and which exhibits a variable electrical resistance in response to applied pressure. The interface further includes a sensor grid including a first set of conductive strips between the first non-conductive layer and the intermediate layer, and a second set of conductive strips between the intermediate layer and the second non-conductive layer. A controller is operable to identify a user input within the sensor grid by monitoring the electrical resistance between the first and second sets of conductive strips.
Description
[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 61 / 865,001, filed August 12, 2013, and U.S. Provisional Patent Application No. 61 / 865,450, filed August 13, 2013, the entire contents of both Incorporated into this case by reference. Background technique [0003] The present invention relates to automotive interiors, and more particularly to user interfaces within vehicles. [0004] A traditional automotive interior includes many switches, buttons, dials, and other physical controls that receive input from the occupant. These control elements are coupled with corresponding mechanisms and systems including entertainment systems, information systems, climate controls, door locks, window regulators, seat position adjusters, cruise control, mirror positions Adjusters, headlights, steering wheel adjusters, and more. Therefore, a typical car interior requires a lot of hardware to enable the driver...
