Abstract
During operation of the engine for a time period from a system-on operation to a system-off operation, the vehicle causes the warming-up determination parameter to be subject to addition when an engine is not in a flow path heat release state where an amount of heat released in the supply flow path is expected to be larger than an amount of heat received in the supply flow path, while causing the warming-up determination parameter to be subject to subtraction when the engine is in the flow path heat release state and a duration time of the flow path heat release state is equal to or longer than a first predetermined time period.
