Abstract: For driver assistance for a combination (8) with a motor vehicle (9) and a trailer (10), a first camera image (19) and a second camera image (20) are generated. A combined image (21) is generated by means of a computing unit (13) by superimposing the camera images (19, 20) such that the second camera image (20) covers a subsection of the first camera image (19), wherein a hitch angle (14) of the combination (8) is determined by means of the computing unit (13). State data of the combination (8) are determined by means of a sensor system (17) and it is determined whether the combination (8) moves forward or backward. The hitch angle (14) is determined based on the state data, if the combination (8) moves forward and based on a change of time-dependent image data, if the combination moves backward. A position of the subsection is determined depending on the hitch angle (14).

Abstract: An image processing method is operable in an image acquisition system comprising a camera arranged to capture successive images with a field of view, FOV of a portion of an environment surrounding a vehicle, the FOV intersecting a window of the vehicle comprising one or more heater elements that are visible within the FOV of the camera. The method comprises: obtaining an image; determining whether one or more sequences of pixels within the image corresponds to an image of a respective heater element, each pixel within the or each sequence of pixels having a colour and an intensity within respective thresholds; correcting, within the image, the or each sequence of pixels corresponding to a respective heater element by replacing pixel values for the or each sequence of pixels with pixel values derived from pixels which do not correspond with a heater element; and displaying the corrected image.

Abstract: A method for time synchronization between a first electronic computing device of a driver assistance system of a motor vehicle and at least a second electronic computing device of the driver assistance system is disclosed. The method includes: generating, by the first electronic computing device, an interrupt signal and a first timestamp of the first clock; sending the interrupt signal to the second electronic computing device; generating, by the second electronic computing device, a second timestamp of the second clock, depending on the received interrupt signal; determining the time difference based on a difference of the two timestamps; and performing time synchronization depending on the determined time difference.

Abstract: A mirror camera system includes a camera fixed to a top of a convertible roof of a vehicle and positioned to capture image data of a scene rear of the vehicle, and a rearview mirror with an integrated display connected to the camera. The mirror camera system is switchable between a camera mode, which shows the image data captured by the camera on the integrated display, and a standard mirror mode, which shows an environment behind the vehicle on a semitransparent reflective surface of the rearview mirror. The rearview mirror includes an electronic control unit that is configured to analyze the image data output from the camera to determine a luminance value of the scene, and further configured to send a signal to switch the mirror camera system from the camera mode to the standard mirror mode when the luminance value of the scene is within a predetermined threshold range.
