In a braking maneuver using a braking assistant () in a motor vehicle (), the braking assistant () initiates an automatic braking maneuver when an actual distance (a) between the motor vehicle () and an object () located ahead of the motor vehicle () becomes less than a specified minimum distance (a). Then an acceleration of the decelerating vehicle () is ascertained during the braking maneuver, and if the acceleration is positive then the braking maneuver initiated by the braking assistant () is automatically interrupted.

Method for performing a braking maneuver using a vehicle braking assistant

A device for increasing the precision of the distance and the relative velocity of a camera-based sensor with the aid of longitudinal acceleration for use in vehicles, e.g., in passive safety applications. In a first arithmetic unit of the inventive device, a correction of a slowly repeated camera-based measurement of the distance to an object is performed with the aid of an internal, longitudinal acceleration signal sampled at a much higher rate, wherein the inventive correction may be performed within an arithmetic unit of the camera, within a passive safety system or in a unit outside the camera and outside the safety system in the vehicle.

The invention relates to a method for adapting the signal processing of at least one sensor device arranged behind a window in a motor vehicle, wherein the adaptation of the signal processing comprises changing at least one detection threshold value if a probability of ice being on the window is detected on the basis of a determined temperature, characterized in that a temperature signal of at least one temperature sensor integrated in the sensor device is used to detect the probability of ice on the window.

Conventional airbag apparatuses have a very large volume for offering the greatest possible protection for the passenger, and therefore block the driver's view of the traffic situation and preclude further steering actions. Additionally, the passenger is endangered if he is in an atypical sitting position. Multi-stage airbag systems permit an adaptation of the degree of deployment to the size and/or position of the passenger, but are very complicated and slow. Proposed is a passenger-protection apparatus having a first airbag for a first stage of deployment, and a second airbag for a second stage of deployment, which occurs after and independently of the first, with the shape of the first airbag and the quantity of gas supplied to it being determined such that, when filled with this quantity of gas, the first airbag has a collision zone that corresponds to the diameter of the steering wheel, and has a short expansion length in the direction of the passenger, in relation to the distance between the collision zone and the passenger. A second airbag, which can be deployed independently, laterally surrounds the first airbag, partially or preferably completely, in the manner of a hose in the filled state, and compresses the first airbag, so the expansion length of the first airbag increases. Whereas the first airbag is deployed early and independently of the position of the passenger, the second airbag can be filled afterward with different quantities of gas when a second acceleration threshold is exceeded, as a function of the position and/or size of the passenger, by a controllable gas source, which can preferably be deployed in stages, thereby establishing the shape of the two airbags and the deformation of the first airbag.
