METHOD FOR OPERATING A TOUCH-SENSITIVE CONTROL SYSTEM AND DEVICE HAVING SUCH A CONTROL SYSTEM

摘要

The invention relates to a method for operating an operating system (10), in particular of a motor vehicle, having the steps: detecting by means of a pressure detection device whether an operating field (14) of the operating system (10) has been exposed by means of an actuating element (12) to a greater pressure than a predetermined pressure threshold value; if it is detected that the operating field (14) is exposed to a greater pressure than the pressure threshold value: outputting of at least one confirmation signal by means of the operating field (14); wherein by means of a detection device, the size of a contact area (22, 22′) of the actuating element (12) that touches the operating field (14) is detected; the confirmation signal is output only if, during the pressure exertion on the operating field (14), it is detected that the contact area (22, 22′) of the actuating element (12) has been changed by a predetermined factor. The invention furthermore relates to a unit with an operating system (10).

1. Method for operating an operating system (10), in particular of a motor vehicle, having the steps:
detecting by means of a pressure detection device whether an operating field (14) of the operating system (10) has been exposed by means of an actuating element (12) to a greater pressure than a predetermined pressure threshold value; if it is detected that the operating field (14) is exposed to a greater pressure than the pressure threshold value: outputting of at least one confirmation signal by means of the operating field (14), wherein by means of a detection device, the size of a contact area (22, 22′) of the actuating element (12) that touches the operating field (14) is detected, the confirmation signal is output only if, during the pressure exertion on the operating field (14), it is detected that the contact area (22, 22′) of the actuating element (12) has been changed by a predetermined factor; wherein the detection of the change of the contact area (22, 22′) is used to protect against undesired erroneous triggering.
