Abstract

A method for operating a data processing unit of a driver assistance system, the unit including main and slave computers. The main computer ascertains surroundings data from a surroundings detection system by using a processing specification. The slave computer operates a communication interface of the data processing unit, using a communication instruction. The method includes initializing, a first testing, a carrying out, a second testing and a forwarding. In initializing, the main computer, in response to a signal, is initialized by performing an initialization instruction on the main computer. In the first testing, the slave computer, in response to the signal, is initialized by performing a self-test instruction on the slave computer. In the carrying out, the communication instruction is performed on the slave computer to send and/or receive data via the communication interface, when the slave computer is tested and while the main computer is initialized. In the second testing, the main computer is tested by performing a test instruction on the slave computer, when the main computer is initialized. In the forwarding, the surroundings data are forwarded via the communication in…
