Abstract: A method for monitoring an image sensor, the image sensor having a communication interface for communicating with an external monitoring unit. In the method, a request signal generated by the monitoring unit is read in via the communication interface, a test pattern generated by the image sensor is modified using the request signal, and the modified test pattern is output to the communication interface, in order to have the modified test pattern evaluated by the monitoring unit.

Abstract: A method for operating a data processing unit of a driver assistance system, the unit including main and slave computers. The main computer ascertains surroundings data from a surroundings detection system by using a processing specification. The slave computer operates a communication interface of the data processing unit, using a communication instruction. The method includes initializing, a first testing, a carrying out, a second testing and a forwarding. In initializing, the main computer, in response to a signal, is initialized by performing an initialization instruction on the main computer. In the first testing, the slave computer, in response to the signal, is initialized by performing a self-test instruction on the slave computer. In the carrying out, the communication instruction is performed on the slave computer to send and/or receive data via the communication interface, when the slave computer is tested and while the main computer is initialized.

Abstract: In a method for testing an image sensor having (i) regular pixels and test pixels, of which each is interconnected with one of two predefined voltage values, and (ii) a signal processing unit for providing digital signal values for output voltages of the pixels and test pixels, the following steps are performed: receiving digital signal values of the test pixels; and using the signal values of at least one proper or improper subset of the test pixels for testing the image sensor, all test pixels of the subset being interconnected with a first of the two voltage values. Using the test pixels for testing allows testing during ongoing operation, i.e., during reception of regular image signals.

Abstract: A night vision device for a vehicle is provided, in which a travel path that is set or is to be set is inserted in an image recorded by a camera, the travel path being determined from an evaluation of a location-finding or travel direction sensor.

Abstract: A display unit for representing a steering-wheel angle, to be modified, of a vehicle is provided, which has a multitude of adjacently arranged indicator elements. One or more of these indicator element(s) is/are illuminated to indicate a modification in the steering-wheel angle and possibly the steering direction.

Abstract: An apparatus is described for assisting driving of a vehicle having at least two driver assistance systems and having an output device or element for communicating information items of at least one of the driver assistance systems to a driver of the vehicle. To relieve the strain on the driver, a control device or element, configured as an information coordinator and connected at its input side to the driver assistance systems and at its output side to the output device is provided for controlling information items of the driver assistance systems to be communicated to the driver.

Abstract: The present invention relates to a method and a device for transforming an object image, e.g., using a rotation and/or scaling, for showing it on a display unit having a matrix-shaped array of target image points. In order to achieve a rapid and exact representation of the rotated object at relatively low expenditure, the present invention provides, for at least a portion of the target image points, determining source image points by an inverse transformation, and comparing the source image points to pre-stored object image points. From this comparison, the target image point data of the target image points are ascertained. Furthermore, a suitable image of such a transformation is created.

Abstract: Proposed is a method for transmitting data in a vehicle, and a driver-information device, where an output unit is connected to processing devices by a data bus. This allows an output for all of the processing devices connected to the data bus to occur centrally in the output unit, whereby, on one hand, only one output unit is necessary for a plurality of processing devices, and on the other hand, processing devices of different manufacturers can be connected to one output unit, when a common data-bus protocol is present.
