The sensor device (S) uses at least one ultrasonic transmission element and at least one ultrasonic reception element with respective directional characteristics, each of which is coupled to an electronic signal processing circuit, controlling both elements and evaluating the reflected ultrasonic signals. The sensor device is positioned within the passenger space along the central longitudinal axis of the vehicle behind a sliding roof opening surface. The sensor device may be positioned adjacent the centre point of the roof of the passenger space. |
