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. In the second testing, the main computer is tested by performing a test instruction on the slave computer, when the main computer is initialized. In the forwarding, the surroundings data are forwarded via the communication interface by performing the communication instruction on the slave computer, when the main computer is tested.

An interface and a method for image data transmission that is used for data transmission through a plurality of data lines is described, the correctness of the transmitted data being checked by reference to control data. The checking capability is achieved in that at least one item of control data is transmitted through each data line.

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.
