VEHICLE CONTROL SYSTEM

One or more first processors are configured to execute a process including: performing generation of instruction information indicating a control value for the control target; performing a reset process of resetting the control value for the control target to an initial value when a specific condition is satisfied in a calculation state in which various calculations including the generation of the instruction information are executable; returning to the calculation state after the reset process; generating a reliability flag indicating reliability of the instruction information; and transmitting the generated instruction information and the generated reliability flag to the second control unit. One or more second processors are configured to execute a process including executing control of the control target, based on the received instruction information and the received reliability flag.
