Abstract
A computer system for vehicles is provided in which the functions are partitioned among the computers of the computer system. A first computer takes over the driving-related functions, while a second computer having greater computing power takes over entertainment-specific functions.

10. A computer system in a vehicle, comprising:
-
a first processing unit in the vehicle, configured to perform critical driving-related functions, wherein the first processing unit is substantially closed from end-user modifications; a second processing unit in the vehicle, configured to perform an auxiliary set of functions, wherein the second processing unit is configurable by the end-user; and a data transfer connection between the first and second processing units; wherein the system is configured to distribute critical driving-related functions to the first processing unit and the second processing unit, based at least in part on an availability of the respective processing units and on how processing-intensive the functions are, wherein the first processing unit gives processing-intensive tasks to the second processing unit and the first processing unit executes the processing-intensive tasks if the second processing unit is not available, and wherein the system is configured to distribute the auxiliary set of functions exclusively to the second processing unit. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
