The method may also include detecting the surroundings in a second detection region by an optical camera. The first detection region and the second detection region may at least overlap each other. An optical sensor in the camera may be exposed at least twice within one period of the laser scanner. A first exposure time for a first exposure of the at least two exposures of the optical sensor may be chosen and synchronized with the laser scanner so that the first exposure occurs within a first time window, in which the laser scanner scans the first detection region.

Abstract: A connection arrangement for fixing a lid to a filter housing and to a filter element, by which an insertion opening in the filter housing can be closed, includes a holding element on the filter element and a locking element on the lid. The holding element can be fixed by a contact surface for contacting the locking element in a recess of the filter housing. The holding element has a latching geometry with which it can be latched in the recess of the filter housing. The locking element is a shaft with a bolt rod and a handle part. The shaft is guided through the lid such that the lid and the filter element in the latching position can, by the bolt rod and a contact surface formed as a ramp on the holding element, which engage with one another by turning the locking element, be spanned against each other.

Abstract: A mounting direction determination device and a mounting direction determination method of an acceleration sensor which can automatically determine the direction of the acceleration sensor mounted on a vehicle. The mounting direction determination device determines a mounting direction, relative to a vehicle, of the acceleration sensor that is capable of detecting a first acceleration in a first direction and a second acceleration in a second direction. A mounting direction determination unit determines the mounting direction by comparing values actually measured by the acceleration sensor with determination reference data. The determination reference data specifies a combination of the detection results of the first acceleration and the second acceleration and the mounting directions.

Abstract: A device and a method for controlling a shading system of vehicle windows. A camera system detects image data of the head of a driver. The image data is evaluated to determine a gaze direction of the driver either as a function of a current pose of the head or body position of the driver ascertained based on the image data or as a function of eye positions of the driver determined based on image data. The shading system is controlled when the determined current gaze direction is looking in an interior rear view mirror, in the direction of the rear window, in the direction of one of the side windows, a reverse gear of the vehicle is set/activated, and the vehicle is in operation/activated. The control involves suspending or switching off a current shading/darkening of the rear window or of the side window in the gaze direction of the driver.

Abstract: Methods are disclosed for detecting and lessening fuel starvation conditions in an operating fuel cell system. The fuel cell systems comprise a solid polymer electrolyte fuel cell with a regulating apparatus for regulating the pressure of fuel supplied to the anode inlet of the fuel cell, in which the outlet pressure from the regulating apparatus oscillates during operation. The methods involve monitoring an electrical output of the fuel cell during operation, determining the amplitude of oscillation in the electrical output, and then, if the determined amplitude of oscillation in the electrical output exceeds a predetermined amount thereby indicating a fuel starvation condition, taking a remedial action to lessen the fuel starvation condition.
