Abstract
A control device for preventively actuating a vehicle safety device, comprises a decision stage which issues a triggering decision the vehicle safety device if travel behavior of the vehicle which is critical for safety is detected, based on dynamic translational movement parameters. In addition, a plausibility checking stage checks the triggering decisions, evaluates it as implausible (and prevents triggering of the vehicle savety device) if an evaluation of the time profile of parameters which are sensed in the vehicle, such steering angle, activation of pedals, yaw rate or lateral acceleration, reveals that the travel behavior which is critical for safety corresponds, within predefinable limits, to a desired travel behavior. A travel behavior which is brought about in a deliberate and controlled fashion is considered to be a desired travel behavior.

9. Control apparatus for a motor vehicle, for preventively actuating a vehicle safety device for protecting vehicle occupants and/or road users, said apparatus comprising:
-
a decision stage which generates a triggering decision for the vehicle safety device if a travel behavior of the vehicle which is critical for safety is determined, based on dynamic vehicle movement parameters; and
a plausibility checking stage for checking plausibility of the triggering decision;
wherein,the plausibility checking stage evaluates the triggering decision as implausible and prevents actuation of the vehicle safety device if an evaluation of time profile of parameters that are sensed in the vehicle reveals that the travel behavior which is critical for safety corresponds, within predefinable limits, to a desired travel behavior, which is brought about in a deliberate and controlled fashion by a vehicle operator. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for preventively actuating a vehicle safety device in a motor vehicle, said method comprising:
-
generating a triggering decision for the vehicle safety device only if a travel behavior of the vehicle which is critical for safety is detected, based on dynamic vehicle movement parameters;
evaluating time profiles of parameters that are sensed in the vehicle;
determining the triggering decision is implausible, if, based on said evaluating, it is concluded that the critical travel behavior corresponds, within predefinable limits, to a desired travel behavior, which is brought about by the driver in a deliberate and controlled fashion;
prevent actuation of the vehicle safety device in response to a determination that the critical travel behavior corresponds within said limits, to said desired travel behavior.

18. A method for controlling operation of a vehicle safety device, said method comprising:
-
determining dynamic behavior of the vehicle based on vehicle movement parameters;
detecting occurrence of a critical dynamic behavior of the vehicle based on said determined dynamic behavior;
generating a trigger signal for actuating the vehicle safety device upon detection of said critical dynamic behavior;
determining a desired travel behavior based on vehicle control parameters that have values or profiles that are indicative of deliberate vehicle control activity by a vehicle driver;
comparing said detected critical dynamic behavior of the vehicle with the desired travel behavior; and
inhibiting a triggering of said vehicle safety device when said critical dynamic behavior corresponds within specified limits to said desired traveling behavior.
