Abstract
A steering column switch system includes a device for recording the position of the steering column switch. The device converts the switching position that has been adopted by the steering column switch into a bit pattern. A decoding unit assigns a switching function to the bit pattern of the position that has been identified. Another device recognizes errors during the detection or transmission of the bit patterns. The decoding unit modifies the assignments between the bit patterns and the switching functions to be initiated as a function of the bit pattern errors.
Claims12
A steering column switch system for a motor vehicle, the system comprising:
- a detector for detecting the position of a steering column switch and for converting detected switch positions into corresponding bit patterns;
- a decoder for assigning switch functions to the bit patterns;
- and
- an error identifier for recognizing bit pattern errors;
- wherein the decoder changes the assignments between the bit patterns and the switch functions upon the error identifier recognizing a bit pattern error.
