Sensor system for vehicles, in particular motor vehicles, for detecting the vehicle speed, the vehicle level and/or the state of the vehicle suspension, arrangement for such a sensor system and vehicle having such a sensor system

A sensor system for motor vehicles, for detecting a vehicle speed, a vehicle level and/or a state of the vehicle suspension, the system comprising:

• at least one first sensor for measuring a level of a point on a body of the vehicle;
• at least one second sensor for measuring an acceleration of a point on the vehicle perpendicular to a reference plane on the vehicle;
• and
• an evaluation unit, configured to determine a vehicle speed from a distance between axles of the vehicle and a signal curve, determined over a period of time, of a level signal supplied by the at least one first sensor and/or a signal profile, determined over a period of time, of an acceleration signal supplied by the at least one second sensor, wherein the vehicle speed is determined by correlating the distance between the axles of the vehicle and a time interval between two similar sections of the signal curve of the level signal and/or a time interval between two similar sections of the signal curve of the acceleration signal.
