Patent ID: 8395491

Claim:
Method for controlling driving stability of a vehicle, comprising: establishing by means of detection devices a current steering angle and a current lateral acceleration; determining a model-based stable limit speed of the vehicle, wherein the model-based stable limit speed is determined based on the current steering angle and the current lateral acceleration wherein a driving speed is compared to the model-based stable limit speed of the vehicle, and based on a result of comparison, the driving speed is adapted to the limit speed when the driving speed exceeds the limit speed; and wherein the model-based stable limit speed is determined according to the recursive relation v limit = l * a q δ - Δδ tol - a q * EG where δ is a steering angle of the steering wheel at the front wheels ξ is wheel base EG is a self-steering gradient of the vehicle α G is a vehicle lateral acceleration υ lim it is a stable limit speed Δδ tol is a tolerated steering angle deviation compared to the linear case.
