Abstract: An object of the present invention is to provide a vehicle control device and a vehicle control system capable of further reducing system cost in failure mitigation. The vehicle control device includes a master ECU and one or more client ECUs. The master ECU generates a safety process list on a basis of a predetermined failure operation pattern and transmits the safety process list to each of the client ECUs when detecting a failure of any one of the client ECUs, the safety process list includes one or more safety processes and an execution start time limit corresponding to each of the safety processes, each of the client ECUs switches an operation mode from a normal mode to a failure operation mode in response to reception of the safety process list, and starts execution of each of the safety processes by a corresponding execution start time limit, the failure operation pattern is configured such that each of the safety processes is executed by a client ECU having a memory capacity capable of executing the safety process, and the failure operation pattern is configured such that the same safety process is not executed by a plurality of client ECUs.

Abstract: Provided is a technology capable of adding a new function by updating a program of an in-vehicle computer system. An in-vehicle computer system includes a plurality of ECUs. Each ECU is able to communicate with at least one other ECU via a communication bus. An in-vehicle computer system includes a measurement means that measures an ECU state for the ECUs, an estimation means that estimates a vehicle state based on the ECU state and a connection configuration of a communication bus, and a management means that acquires an update program and execution conditions of the update program. The management means selects a first ECU that is to execute the update program based on the vehicle state and the execution conditions. The first ECU executes the update program. The management means determines whether or not an output delay constraint of the update program is satisfied. The management means terminates execution of a redundancy program redundant to the update program.
