摘要:
A control device and a method for triggering a passenger protection arrangement for a vehicle are provided, at least two acceleration signals being provided by at least two acceleration sensors oriented in different spatial directions. The orientations are angled in relation to a coordinate system oriented toward the vehicle longitudinal direction. The at least two acceleration signals are transformed on at least two axes of the coordinate system. The triggering signal is generated as a function of the comparison of the at least two acceleration signals and the transformed acceleration signals. The passenger protection arrangement is triggered as a function of the triggering signal.
摘要:
In a method for triggering a passenger protection arrangement for a vehicle, a feature vector including at least two features is determined, the two features being derived from at least one signal of an accident sensor system. The feature vector is classified as a function of a comparison with at least one class boundary. The passenger protection arrangement is triggered as a function of the classification. A confidence measure is determined as a function of a position of the at least one feature vector in relation to the at least one class boundary. The triggering of passenger protection arrangement takes place as a function of this confidence measure.

A vehicle dynamics behavior reproduction system capable of describing accurately behavior of a motor vehicle in a lateral direction even for nonlinear driving situation includes a vertical wheel force arithmetic module (105), a lateral wheel force arithmetic module (110), a cornering stiffness adaptation module (115), a state space model/observer unit (120), a selector (130), a delay module (135), and a tire side slip angle arithmetic module (125). Vertical wheel forces (FZij) and tire side slip angles (αij) are determined by using sensor information and estimated values while lateral wheel forces (FYij) are determined in accordance with a relatively simple nonlinear approximation equation. The lateral wheel force (FYij) and the tire side slip angle (αij) provide bases for adaptation of cornering stiffnesses at individual wheels. Vehicle motion is accurately described to a marginal stability by using adapted cornering stiffnesses (Cij) and other information.

A method for activating at least one safety device that has a first step of acquiring at least two features from at least one signal of a crash sensor system in order to form a feature vector from the features acquired. In a second method step, the formed feature vector is subsequently classified with the aid of a classifier based on the statistical learning theory in order to classify the feature vector in one of at least three possible feature classes. As a third method step, the safety devices are activated in accordance with an activation instruction for the feature class in which the feature vector was classified.
摘要:
In a method and a control unit for triggering passenger protection devices, at least one characteristic is extracted from at least one variable. A crash is classified on the basis of this at least one characteristic, and the crash classification results in the making of a triggering decision. The passenger protection devices are then triggered as a function of the triggering decision. The triggering decision is made by providing a sequence control which, as a function of at least one progression variable, activates or deactivates a plurality of functions for the crash classification and/or defines which at least one characteristic is used for the particular function.
