Method and apparatus for influencing the transverse dynamics of a vehicle
Abstract:
In a method and apparatus for influencing transverse dynamics of a vehicle, for a chassis intervention is carried out when an intervention condition is met. The intervention condition is met when the value of a determined transverse dynamics disturbance variable is higher than a disturbance variable threshold value, and when one or a group of the following criteria is met: the longitudinal speed of the vehicle is higher than a longitudinal speed threshold value of the vehicle; the sensorially detected actual yaw rate is lower than or equal to a calculated current yaw rate; a braking torque variable describing a braking torque and caused by braking by the driver is lower than or equal to a braking torque threshold value; a spring variable describing the current spring path of a chassis spring of a vehicle wheel is lower than or equal to a spring path threshold value; a differential spring variable describing the difference between the current spring paths of the two chassis springs of a vehicle axle is lower than or equal to a differential spring path threshold value; and a slip difference variable describing the slip difference between two vehicle wheels is lower than or equal to a slip differential threshold value.
