Abstract: A method for detecting lost image information via a lighting device and an optical sensor. The lighting device and the optical sensor are controlled so as to be chronologically aligned with each other. A visible spacing region in an observation region of the optical sensor is determined from the chronological alignment of the control of the lighting device and the optical sensor. A recording of the observation region with the optical sensor is generated via the aligned control. Image information is identified in the recording in regions outside of the spacing region visible in the image, so as to make the identified image information accessible.

Abstract: A method for operating an internal combustion engine. The internal combustion engine has multiple cylinders and the cylinders are assigned a respective exhaust valve and intake valve. The internal combustion engine has a crankshaft, an intake camshaft, and an exhaust camshaft. Initially, the internal combustion engine is operated in a first operating state. A second operating state of the internal combustion engine is set by the intake camshaft being adjusted late relative to the crankshaft in comparison to the first operating state and the exhaust camshaft being adjusted early relative to the crankshaft in comparison to the first operating state. To set the second operating state, the intake camshaft is adjusted late by a first value which is in a range from 50-120 crank angle degrees and the exhaust camshaft is adjusted early by a second value which is in a range of 1-35 crank angle degrees.

Abstract: A method for tracking an object. A first coordinated control of a lighting device and an optical sensor is assigned to a first visible distance range. A first recording of the first visible distance range while illuminated by the lighting device is recorded with the optical sensor. If the object is detected in the first recording within the first visible distance range, a distance between the detected object and the optical sensor is determined. A second coordinated control of the lighting device and the optical sensor and an assigned, second visible distance range are determined such that the object detected in the first recording is located in a center of the second visible distance range. A second recording of the second visible distance range while illuminated by the lighting device is recorded with the optical sensor by the second coordinated control.

Abstract: A method for locking and releasing a securing device of a vehicle coupling of a vehicle includes switching the securing device between a locked state and a released state by a control command output by an authorization unit where the authorization unit outputs the control command after receiving an initiation command transmitted to the authorization unit by an interface and where a wireless communication interface and a local physical interface are useable as the interface.

The initiation command is transmitted to the vehicle by the control center via the wireless communication interface as a function of the sensor data. When there is no communication connection between the control center and the vehicle, it is only possible to output the initiation command via the local physical interface.
