Abstract
A method is described for generating an item of information for indicating an airborne state for a vehicle. The method has a step of receiving a rotational speed signal which represents a rotational speed of at least one drive wheel of the vehicle. The method also has a step of generating the information for indicating an airborne state based on a comparison of a profile of the rotational speed signal with at least one reference profile for the rotational speed signal.

A computer-implemented method, comprising:
- generating, by a sensor arrangement, an electronic rotational speed signal, which represents a rotational speed of at least one drive wheel of a vehicle;
- receiving, by a processor, the electronic rotational speed signal from the sensor arrangement;
- generating, by the processor, a first electronic item of information indicating an airborne state of a vehicle (a) based on a comparison of a profile of the rotational speed signal with at least one reference profile for the rotational speed signal, and (b) without determining an acceleration of the vehicle;
- receiving, by the processor, a further signal;
- generating, by the processor, a second item of information for indicating the airborne state based on a comparison of a profile of the further signal with at least one reference profile for the further signal, the further signal indicating that fewer of particular components act on a structure of the vehicle compared with the at least one reference profile for the further signal;
- and
- combining, by the processor, the further signal for indicating the airborne state with the first electronic item of information for indicating the airborne state in order to generate an airborne state signal;
- wherein:
- (a) the structure of the vehicle is at least one seat of the vehicle, the further signal is a seat occupancy signal that represents a seat occupancy of the at least one seat, and the particular components are forces other than gravity;
- (b) the structure of the vehicle is at least one tire of the vehicle, the further signal is a tire load signal that represents a tire load of the at least one tire, and the particular components are loads;
- or
- (c) the structure of the vehicle is at least one shock absorber of the vehicle, the further signal is a shock absorber load signal that represents a shock absorber load of the at least one shock absorber, and the particular components are loads.
