ABSTRACT:
A sensor arrangement for detecting the influence of cross wind on the handling of a motor vehicle comprising pressure measuring points situated on opposite sides of the vehicle for the measuring of the air pressure existing in the area of the outer skin of the vehicle body. The pressure measuring points are constructed as bores in the outer skin of the vehicle body. A differential pressure sensor, which detects the differential pressure (Dp) between two vehicle sides, is arranged centrally between two pressure measuring points, and is connected with the two bores by way of hoses or lines which, if possible, should have the same length. For detecting the vehicle's entry into and emergence from a cross wind gust, the sensor filters the detected values of the wind cross force by means of a low pass filter and compares them with the filtered values that were detected immediately before. When the difference between the amounts of the filtered values rises, entry into a cross wind gust is recognized, and when the values fall, emergence form a cross wind gust is recognized.
