Force-sensor for use in control device placed in e.g. facade, of motor vehicle for controlling functions of motor vehicle body during night driving, has reference resistor deposited at outer side of touch zone in dead zone of control device

摘要

The force-sensor (1) has a touch zone (ZT) comprising multiple of sensitive resistance sections (2a-2d) for pressure variations. A reference resistor (3) is deposited at an outer side of the touch zone away from the sensitive resistance sections during a deposition of resistors for the sensitive resistance sections in a dead zone (ZM) of a control device. The reference resistor comprises a resistive ink that is deposited by a screen printing during a same screen printing process of resistive inks of the sensitive resistance sections. Independent claims are also included for the following: (1) a control device comprising a processing unit for deriving a corrected resistance (2) a method for measuring a touch support on a force sensor.
