Syndrome values are employed as a mechanism for synchronization and consistency in a distributed data processing environment. The methods effectively enhance or optimize throughput received by each destination router under node traffic constraints such as power, scheduling and flow constraints that apply to each link between each of a plurality of nodes within the mesh network. During the fuel cutoff control, the ECU performs throttle opening increase control as necessary to set the opening degree of a throttle valve greater than a usual target opening degree that is set when an acceleration pedal is not depressed.
