Motor vehicle with a safety system with a preventive action
In a motor vehicle, such as a passenger car, a preventive-action protection system is provided which includes safety devices that are actuated as a function of information detected by a driving-state sensor system and evaluated in a data evaluation and control device, which compares the detected information with at least one threshold value. When a critical condition of the driving state is detected, the data evaluation and control device actuates at least one safety device assigned to this driving state. Here, a theoretical, lateral-dynamics critical condition is detected and triggering of at least one assigned safety device occurs if a threshold value is exceeded when a current steering angle speed is logically combined with a parameter which represents the current driving-dynamics situation.
