Abstract: The invention relates to a method for detecting an object in an opening area of a first door (5) of a motor vehicle (1) using at least one first distance sensor (9, 10, 11), the at least one first distance sensor (9, 10, 11) being arranged in and/or on the first door (5) and having a detection area (17, 18, 19), in which a current opening angle (?2) of the first door (5) is detected and the detection area (17, 18, 19) is adapted on the basis of the detected opening angle (?2), a state variable of at least one component of the motor vehicle (1) which differs from the first door (5) being determined, the state variable describing a position and/or an operational setting of the at least one component, and the detection area (17, 18, 19) of the at least one first distance sensor (9, 10, 11) additionally being adapted on the basis of the determined state variable.

Abstract: The invention relates to a sensor system for distance measuring for a motor vehicle, comprising at least one ultrasonic sensor with a sensor housing and at least one membrane with a membrane diameter that is capable of being electrically stimulated into vibrations and a control unit for controlling the at least one membrane as well as for detecting vibrations of the at least one membrane, wherein the control unit is configured to stimulate in a measuring mode the at least one membrane into vibrations with a measuring frequency and a measuring amplitude. The control unit is configured to stimulate the at least one membrane in a cleaning mode into such vibrations that the sensor housing is set into vibrations with a housing amplitude that amounts to at least 1% of the membrane diameter. Further, the invention relates to a motor vehicle and a method for cleaning an ultrasonic sensor.
