Abstract
A method and a device are provided for detecting a tendency of a vehicle to tip about a vehicle axis oriented in the longitudinal direction of the vehicle. To this end, a variable is ascertained describing the dynamics of the vehicle linear motion. The detection strategy used for detecting the tendency of the vehicle to tip is selected from at least two detection strategies at least as a function of the variable describing the dynamics of the vehicle linear motion and/or the detection strategy used for detecting a tendency of the vehicle to tip is adapted, at least as a function of the variable describing the dynamics of the vehicle linear motion, to the dynamics of the vehicle linear motion existing at any one time.
Claims21
A method for detecting a tendency of a vehicle to tip about a vehicle axis oriented in a longitudinal direction of the vehicle, comprising the steps of:
- ascertaining a variable for describing dynamics of a vehicle linear motion;
- and performing at least one of:
- (A) selecting a detection strategy from at least two detection strategies, the at least two detection strategies being strategies for detecting the tendency of the vehicle to tip about the vehicle axis oriented in the longitudinal direction of the vehicle, the step of selecting being performed at least as a function of the variable for describing the dynamics of the vehicle linear motion;
- and
- (B) adapting a detection strategy to the dynamics of the vehicle linear motion existing at any particular time, the step of adapting being performed at least as a function of the variable for describing the dynamics of the vehicle linear motion, the adapted detection strategy being a strategy for detecting the tendency of the vehicle to tip about the vehicle axis oriented in the longitudinal direction of the vehicle.
A device for detecting a tendency of a vehicle to tip about a vehicle axis oriented in a longitudinal direction of the vehicle, comprising:
- means for ascertaining a variable for describing dynamics of a vehicle linear motion;
- and
- at least one of (A) means for selecting a detection strategy from at least two detection strategies, the at least two detection strategies being strategies for detecting the tendency of the vehicle to tip about the vehicle axis oriented in the longitudinal direction of the vehicle, the selecting being at least a function of the variable for describing the dynamics of the vehicle linear motion and (B) means for adapting a detection strategy to the dynamics of the vehicle linear motion existing at any particular time, the adapting being at least a function of the variable for describing the dynamics of the vehicle linear motion, the adapted detection strategy being a strategy for detecting the tendency of the vehicle to tip about the vehicle axis oriented in the longitudinal direction of the vehicle.
