Abstract (en)
[origin: WO2013000854A1] The invention describes a vehicle unit and a method for controlling vehicle functions with a microprocessor and connected memory, on which a main operating system which forms the hardware interface for application programs and user interactions is implemented. Provision is made for the microprocessor to be constructed in a microkernel architecture with separate partitions for a main operating system unit (1), a cryptographic unit (4) and a supervision unit (2), wherein the main operating system is set up in the main operating system unit (1), wherein software certificates are stored in the cryptographic unit (4) and a verification program for verifying certificates and software packages is set up therein, and wherein a monitoring program for monitoring the operation of the other partitions of the microkernel architecture is provided in the supervision unit (2).
