A motor vehicle includes a communication device for transmitting and receiving data packages. The communication device has at least one wired interface for transmitting a first data package to a base station external to the motor vehicle and at least one receiving device for wirelessly receiving a second data package. The receiving device is designed to receive the second data package from at least one mobile device external to the motor vehicle. The communication device is designed to transmit the wirelessly received second data package as the first data package in a wired manner.

A method and device for identifying contamination on a protective screen of a lidar sensor may involve determining a sector background noise in a particular sector of a detection region of the lidar sensor and a detection region background noise is determined in a remaining detection region or the entire detection region. Contamination in the sector in question is then determined if the sector background noise is significantly lower than the detection region background noise. Alternatively, or additionally, a sector background noise is determined in the sector in question at different sensitivities of a receiver of the lidar sensor, and contamination in the sector in question is then determined if a sector background noise determined with a higher sensitivity is not significantly higher than a sector background noise determined with a lower sensitivity.

A method for transmitting a data packet from a central electronic computing device to a mobile terminal device using a network system involves transmitting the data packet to an electronic computing device of a motor vehicle of the network system using a mobile telecommunications network. The transmitted data packet is transmitted locally from the electronic computing device using a local network, which is created by the electronic computing device, to the at least one mobile terminal device.

Calibrating a camera and/or a lidar sensor of a vehicle or a robot involves a camera capturing images of a vehicle or robot environment. The lidar sensor emits a real pattern into the vehicle or robot environment in at least one portion of a detection range of the camera, and the real pattern is captured by the camera. A virtual pattern generated in a coordinate system of the lidar sensor is projected onto a virtual plane in the vehicle or robot environment by the lidar sensor. Laser radiation emitted by the lidar sensor penetrates the virtual plane and the real pattern correlating with the virtual pattern is generated on a real projection surface. The real pattern captured by the camera is recalculated onto the virtual plane based on a surface profile of the real projection surface. A rectified virtual pattern is generated in a coordinate system of the camera and the camera and/or lidar sensor is/are calibrated by comparing the virtual pattern and the rectified virtual pattern.

A method for identifying a change of a range of a lidar sensor involves a lidar sensor receiving a reference noise level of infrared radiation. A signal-to-noise ratio of infrared radiation reflected on the reference target and received by the lidar sensor are identified in a reference measurement having a reference target located at a predetermined distance to the lidar sensor. In a driving operation measurement, a current noise level of received infrared radiation is identified and a theoretical distance to a position where the reference target ought to be if, at the current noise level, the same signal-to-noise ratio applies as in the reference measurement is identified from the current noise level. A change in range calculation identifies a difference between the predetermined distance and the theoretical distance. The difference corresponds to the change of the range of the lidar sensor compared to its range during the reference measurement.

A method and a device for detecting the opening state of a garage door or the like, such as a door that restricts entry by a vehicle are provided. A control apparatus generates a predetermined light pattern. A headlight apparatus projects the predetermined light pattern onto the door, while a camera apparatus detects the light pattern projected onto the door. The control apparatus compares the light pattern detected by the camera apparatus with the predetermined light pattern and outputs information signals according to the differences between the detected light pattern and the predetermined light pattern. The differences determine the opening state of the door.
