摘要:
A passenger protection device in a motor vehicle includes at least one airbag, at least one gas generator for filling the airbag, an airbag control device for activating the airbag, means for acquiring the deployment speed of the airbag, and means for regulating the filling quantity of the airbag, taking into account its deployment speed. In order for the passenger protection device to implement a controlled filling of the airbag dependent on its deployment speed, at least one flow-off valve is provided that is situated between the gas generator and the airbag. In addition, controllable actuating means are provided for the sealing of the flow-off valve.

An occupant-protection system for vehicles, including: at least one sensor, which detects the surrounding area of the vehicle and generates sensor signals therefrom; an evaluation device, which analyzes the sensor signals, detects an approaching hazardous situation in advance according to an algorithm for the early detection of a hazardous situation and generates a trigger signal in this case; a seat-adjustment device having at least one actuator for adjusting a seat, the seat-adjustment device having a first speed for a comfort adjustment of the seat and a second, higher speed for the seating adjustment of the seat in response to triggering by the trigger signal. Also provided is a method for activating an occupant-protection system for vehicles.
摘要:
An intrusion sensor which includes a first light guide arrangement and a second light guide arrangement for detecting the severity of an accident in a vehicle. An interval having a width is positioned between the two light guide arrangements. In this case, the first light guide arrangement is positioned in the direction of an intrusion side. The second light guide arrangement is positioned in the direction of the vehicle interior side.

A radar sensor platform for clearance measurement in a vehicle has at least four radar sensors, an input being entered if necessary using an input device indicating that a width measurement of a parking space is desired and the four radar sensors then enlarging their horizontal beam angle and the arrangement for acoustic and/or visual output emitting a signal as a function of the measurement of the parking space width. This signal is, for example, the parking space width or a warning. The horizontal beam angle for the parking space measurement is at least 170°. The side clearances of the vehicle in the parking space may also be displayed. Furthermore, centered parking is possible using the acoustic and visual aids. The radar sensor platform may be installed either in the front and/or rear of the vehicle.
摘要:
A collision prevention method for motor vehicles is provided, in which method obstacles in front of the vehicle are detected by an on-board positioning system, a collision probability is calculated from the position data, and one or more responses to prevent a collision are triggered as a function of the collision probability. At least one of the responses is a preparatory measure accelerating the implementation of a command, which may be output later, to decelerate the vehicle, without the preparatory measure itself having any significant decelerating effect on the vehicle.
摘要:
In a method and a device for driver assistance, traffic elements that point to potential danger zones are detected on the road, using a camera. If such potential danger zones are detected, at least one headlight of the vehicle is controlled in such a way that the potential danger zone is illuminated.
摘要:
A method and a device for bi-directional transmission of data are provided such that an interface for digital communication on a signal line is obtained which is suited for automotive use. In accordance with the present invention, the following are provided: at least one switchable load unit, the load unit of the temporary transmitter being able to be deenergized prior to transmission of the data; and being able to be reenergized after transmission of the data; in each case at least one switchable current-source unit is assigned to the load unit, the current-source unit of the transmitter being able to be clocked to generate the signals to be transmitted via the communication path; and in each case at least one comparator unit is assigned to the load unit, corresponding output signals being generated at the comparator unit of the receiver from the signals transmitted via the communication path.
摘要:
A data transmission method and a transmission/reception device are described, the data transmission taking place via intermediate memories without the transmitter receiving direct feedback from the receiver regarding the success of the data transmission. Furthermore, at least one transmission and/or reception device is described which forms an interface between at least two control units and has intermediate memories.
摘要:
A method and a device for activating and/or deactivating distributed control units is described, the microcomputer of a central control unit delivering corresponding activation or deactivation commands to the decentralized control units over an interface module as part of a point-to-point link.
