Vehicle control device

Abstract

Provided is a vehicle control device capable of improving safety and availability by determining, in response to a failure of a core, a core to which the software is to be moved, determining whether there is a contention in the timings of execution based on software operations after the software is moved to another core, and making an arbitration when there is a contention. The vehicle control device has a CPU 11 that executes a plurality of tasks in clock-synchronization, the vehicle control device including a failure detecting unit 121 that detects a failure of a core 10 on the CPU 11, and an execution timing arbitration unit 124 that allocates a task having been executed by a failed core 10 to a non-failed core 10. When the task having been executed by the failed core 10 is allocated to the non-failed core 10, the execution timing arbitration unit 124 shifts the execution time slot in a manner making the task being executed by the non-failed core 10 executable, thereby setting time slots in which the plurality of tasks are executable.

Dependencies are inferred from the claim text.
