DUAL FUNCTION TOUCH SWITCH WITH HAPTIC FEEDBACK
First Claim
1. A control interface system in a vehicle comprising:
- an input device that receives input of a user to control a plurality of systems of the vehicle;
a plurality of dual function sensors disposed along a surface of said input device, each of the dual function sensors having a first circuit that is sensitive to contact of the user with the surface of said input device and a second circuit sensitive to pressure exerted upon the surface of the input device exceeds a predetermined threshold, wherein the dual function sensor generates a first signal indicating contact of the user with the surface of the input device and generates a second signal indicating that pressure exerted upon the surface of the input device exceeds the predetermined threshold; and
a processing unit which receives the first and second signals and controls the plurality of systems within the vehicle based upon the received signals.

Abstract
A control interface system is disclosed. The system comprises an input device that receives input of a user to control a plurality of systems of the vehicle and a plurality of dual function sensors interposed along a surface of said input device. Each of the dual function sensors includes a first circuit that is sensitive to contact of the user with the surface of said input device and a second circuit sensitive to pressure exerted upon the surface of the input device greater than a predetermined threshold. The dual function sensors generate a first signal when the first circuit senses the contact of the user and generate a second signal when the second circuit senses the pressure exerted upon the surface of the input device. The system further includes a processing unit which receives the first and second signals and controls the plurality of systems within the vehicle based upon the received signals.

15. A user input device for controlling a plurality of adjustable settings of one or more systems in a vehicle comprising:
-
a plurality of dual function sensors disposed along a frontal surface of said device, each of the dual function sensors having a contact sensitive circuit, a pressure sensitive circuit, and a feedback circuit, wherein for each of the plurality of dual function sensors; the contact sensitive circuit is configured to generate a first signal indicating contact between a user and the dual function sensor and a location thereof; the pressure sensitive circuit is configured to generate a second signal indicating that an amount of pressure exceeding a predetermined threshold is being applied to the dual function sensor; the feedback circuit is configured to generate feedback to the user indicating that at least one of the contact sensitive circuit and the pressure sensitive circuit of the dual function sensor has been activated; a central processing unit configured to receive the first signals and the second signals from the plurality of dual function sensors and to determine a location and type of user input based on the received signals, wherein said user input controls a current adjustable setting of the plurality of adjustable settings. - View Dependent Claims (16, 17, 18, 19, 20, 21)
