Device for data transmission between vehicle sensors and a processor in a controller

摘要

A device is proposed 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 will then transmit the SPI data telegrams to the processor of the control unit. By using an alter bit, it is possible for the processor of the control unit to retrieve either 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, the interface module supplementing missing data if necessary. By counting out the edges, it is possible for the interface module to recognize the data telegrams from the sensors.
