Abstract
The invention relates to a method for transmitting sensor signals, comprising the following steps: a first sensor (4), in particular a rotational speed sensor, supplies an alternating signal, which is present in the form of a sequence of sensor pulses (50) and pulse pauses (52) of predetermined duration, wherein in the pulse pauses (52) additional data (54) is transmitted as a bit sequence and wherein the bit sequence contains at least one free bit (56); a binary information sequence (60) comprising data from at least one further sensor (12, 14, 22, 30, 38a, 38b, 38c) is generated, which has a transmission length of a plurality of bits; and the data of the first sensor (4) and of the at least one further sensor (12, 14, 22, 30, 38a, 38b, 38c) is transmitted through a common data line (18) in that a processing unit (20) distributes the information sequence (60) to a plurality of chronologically sequential bit sequences and the at least one free bit (56) of the additional data (54) is assigned at least one bit of the information sequence (60). The information sequence (60) is thus reliably transmitted, even when it contains more bits than there are free bits available in the addition…
