Abstract

A device for data transmission between vehicle sensors and a control unit, which is used to decode data telegrams having sensor data from the vehicle sensors and to reformat them into SPI (serial peripheral interface) data telegrams. Furthermore, an interface module of the control unit transmits the SPI data telegrams to the processor of the control unit. By using an alter bit, the processor determines whether to retrieve the newest sensor data or the preceding sensor data. The interface module converts the sensor data in each case into a 10-bit data field of an SPI data telegram, into which the interface module may supplement missing data. By counting out the edges, it is possible for the interface module to recognize the data telegrams from the sensors.
