Abstract
The present device relates to a system and method for controlling the driving stability of a vehicle utilizing variables that characterize a driving situation of the vehicle and are detected in a process. The system and method include determining an expected future behavior of the vehicle, checking the expected future driving behavior with respect to a critical driving situation and executing a vehicle intervention during stable driving conditions to prevent the vehicle from entering a critical driving situation. The intervention may include a brake intervention or an engine intervention.

26. A method for controlling driving stability of a vehicle using variables that characterize a driving situation of the vehicle, the method comprising:
-
determining driver actions from detected variables;
determining an expected future driving behavior of the vehicle based on the determined driver actions;
checking the expected future driving behavior with respect to a critical driving situation; and
executing at least brake interventions or engine interventions during stable driving behavior when a critical driving situation is expected in the future. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)

45. A system for controlling driving stability of a vehicle including sensors (1-5) measuring variables that characterize driving behavior of the vehicle, the system comprising:
-
a unit (8) for evaluating the measured values of the variables;
a device for generating control signals for controlling at least one of a brake intervention or an engine intervention;
a device for determining a driver action from the values of the measured variables;
a device for determining values of variables that characterize a driving dynamics of the vehicle and can be derived from the measured variables and vehicle constants (I, EG), wherein the determined values are values expected in the future due to the determined driver action;
a comparator for comparing the values of these variables to be expected with threshold values for these variables; and
a controller for controlling brake and/or engine interventions depending on the result of the comparison. - View Dependent Claims (46, 47, 48, 49, 50, 51, 52)
