摘要:
An apparatus for protecting a vehicle occupant that triggers a restraint means as a function of the vehicle occupant's motion in the context of an accident. The motion is predicted in that by using an occupant detection system and an impact sensor system, a height of the center of mass of the vehicle occupant and a force action on the vehicle occupant are determined, and the motion of the vehicle occupant is thereby predicted.
摘要:
A method for triggering restraint devices is provided, in which the restraint devices are triggered as a function of a collision signal. The method is launched, however, when the collision signal exceeds a noise threshold. Now a time required for the collision signal to exceed the noise threshold is taken into account in determining the triggering time for a specific restraint device.
摘要:
Filtration media (5) containing natural fiber and a flocculant are effective to flocculate fine particles from runoff in sloped land, ditches, gullies, and construction sites. The filtration media may be in the form of a substantially planar mat product (8), e.g. an erosion control mat, or in tubular form (6).
摘要:
Fiber filtration tubes containing flocculant are produced by winding a preformed mat of natural fibers about a mandrel. The tubes may be joined end to end to produce products of significant length, and are highly suitable in removing even very fine sediment during use in erosion control.
摘要:
A method for triggering an occupant protection device in a vehicle including the steps: detecting a first measured variable and simultaneously generating a corresponding first signal for indicating a necessity for triggering at least one occupant protection device; detecting an acceleration value in the z direction and simultaneously generating a corresponding second signal; calculating a trigger signal for triggering at least one occupant protection device as a function of the first and second signals, and triggering the at least one occupant protection device as a function of the calculated trigger signal. An appropriate device is also described.
摘要:
Proposed is a device for triggering a restraining system in a vehicle, the device triggering the restraining system as a function of a mass estimate of an impact object. In this context, the device is configured such that it performs mass estimates as a function of at least one pre-crash signal, at least one vehicle datum, the own vehicle speed, and at least one impact signal.
摘要:
A device is provided for triggering a restraint means, e.g., a two-stage deployment airbag, the device triggering a second airbag stage as a function of a criterion, derived from the acceleration signal, and the closing velocity. The criterion is, in particular, the deployment time for the first airbag stage. As a function of the deployment time of the first airbag stage and the closing velocity, triggering classes are established which in turn define the deployment time for the second airbag stage.
摘要:
A device for determining the instant a vehicle makes contact with an impact object. The device determines the instant of contact by approximating a signal derived from an acceleration signal using a function.
摘要:
A method for activating a restraint system in a vehicle, in which the restraint system is activated as a function of a speed, an activation characteristic, and at least one quantity derived from an acceleration signal, and in which the at least one quantity exceeds a threshold function that is set as a function of the impact speed and a required activation time. The activation characteristic of a particular accident type runs linearly to a first impact speed value. The activation characteristic runs with a second slope between the first impact speed and a second impact speed value, the first and the second impact speed value depending on the particular vehicle type.
摘要:
A method and a device for activating a restraining arrangement, in which the restraining arrangement is triggered as a function of the crash type and/or the crash severity. The crash type is derived from a signal characterizing the crash. The crash type is ascertained by analyzing signal and slope values of the signal characterizing the crash using threshold values. The crash severity is derived from the crash type and information about the velocity of vehicle.
