11. A method of traffic sign recognition in a driver assistance system of a motor vehicle driving along a road, wherein the driver assistance system includes a camera, said method comprising the following steps performed in the driver assistance system: a) with the camera, recording image data of at least one image of a vehicle environment outside of the vehicle that includes a main sign and an auxiliary sign associated with the main sign; b) evaluating the image data and thereby recognizing a presence of the main sign and classifying main sign information of the main sign; c) evaluating the image data and thereby recognizing a presence of the auxiliary sign; d) performing pattern recognition on the image data and thereby recognizing and classifying any available pattern information of the auxiliary sign; e) performing text recognition on the image data and thereby reading and interpreting textual information of the auxiliary sign; f) obtaining situational information regarding the motor vehicle, a current operation of the motor vehicle, or a condition of the vehicle environment; g) automatically assessing a relevance of the main sign by comparing the situational information with the interpreted textual information of the auxiliary sign and with any available classified pattern information of the auxiliary sign, and thereby determining whether that the main sign is relevant only when the situational information falls within a scope of the interpreted textual information of the auxiliary sign and the available classified pattern information of the auxiliary sign; and h) in response to the step g) having determined that the main sign is relevant, activating a driver assistance feature of the driver assistance system based on the classified main sign information of the main sign.

The method according to claim 11 , wherein the driver assistance feature comprises searching for an upcoming further sign in subsequent image data recorded by the camera at a subsequent time, in response to the situational information at the subsequent time falling within the scope of the interpreted textual information and the available classified pattern information of the auxiliary sign at a previous time.
