Abstract: The invention relates to a method for operating a driver assistance system (2) for a motor vehicle (1), in which a driver-specific blind spot (3) in the surroundings (4) of the motor vehicle (1) is determined, wherein at least one boundary edge (8, 9) of a driver-specific field of vision (5) of a motor vehicle driver is determined as a function of a movement behavior of the motor vehicle driver's head and/or as a function of the visual faculty of the motor vehicle driver, and the dimension (a2) and/or a local position of the driver-specific blind spot (3) in the surroundings (4) of the motor vehicle (1) is determined as a function of the determined boundary edge (8, 9) of the driver-specific field of vision (5).

Abstract: The invention concerns a method and a distance determination device for determining the distance between at least one sensor device and an object in the detection region of the sensor device. A conventional method of this type is further developed in accordance with the invention in order to decide whether or not there is the danger of collision due to a relative motion between the object and the sensor device. This danger of collision is determined in accordance with the invention by means of a threshold value comparison between the change of a relative speed determined by the sensor device between the object and the sensor device and a predetermined change threshold value.

Abstract: A process for determining the distance between a distance sensor and an object, wherein an analog input signal is directed to a transmitter of the distance sensor. The transmitter emits a wave which is reflected by the object. A receiver of the distance sensor receives the reflected wave and thereupon emits an analog output signal whose level is dependent upon the distance and/or the type of object. The output signal is amplified by a subsequently added amplifier. The amplifier signal is directed to an analog/digital converter and is converted into a digital signal. The digital signal is directed to an evaluation circuit for the computation of a distance value. The signal amplification of the amplifier is controlled in an adaptively dependent manner on the level of the output signal and/or in a manner dependent on the signal value of an amplification signal made available by the evaluation circuit which is characteristic of an anticipated distance range.
