Method and device for recognizing raised wheels of a vehicle
First Claim
1. A method of detecting a transverse-dynamically hazardous operating state of a vehicle, comprising:
- determining a variable describing a rotational speed of at least one wheel on an axle;
determining a first variable describing a vehicle transverse dynamics from at least the variable describing the rotational speed;
determining at least one second variable describing the vehicle transverse dynamics from a sensor signal;
detecting a transverse-dynamically hazardous operating state at least as a function of the first variable and the second variable, the transverse-dynamically hazardous operating state corresponding to one of when the at least one wheel on the axle lifts off a roadway and when an imminent danger of the at least one wheel lifting off the roadway is present;
determining the transverse-dynamically hazardous operating state as a function of an engine torque acting upon the axle; and
while determining the transverse-dynamically hazardous operating state, determining whether the axle is one of driven and non-driven.

Abstract
A method of detecting a transverse-dynamically hazardous operating state of a vehicle, where a variable describing the rotational speed of at least one wheel on an axle is determined; a first variable describing the vehicle transverse dynamics is determined from at least the one variable describing the wheel rotational speed; at least one second variable describing the vehicle transverse dynamics is determined from sensor signals; and the transverse-dynamically hazardous state is detected at least as a function of the first variable describing the vehicle transverse dynamics and the second variable describing the vehicle transverse dynamics. The transverse-dynamically hazardous operating state is defined by this wheel on the axle lifting off the roadway or by an imminent danger of this wheel lifting off the roadway; and the transverse-dynamically hazardous operating state is detected as a function of the engine torque (Mmot) acting upon this axle.
