<p>PROBLEM TO BE SOLVED: To perform the warm-up operation in accordance with the condition of an internal combustion engine and a transmission. SOLUTION: The warm-up control device includes a cooling water sensor 105 to sense the temperature of cooling water in the internal combustion engine 10 and an oil temperature sensor 107 to sense the oil temperature in the transmission 11, and the warm cooling water stored warm in a heat accumulation tank 101 during the engine being in operation is distributed in accordance with the sensed temperature of the cooling water and the sensed temperature of the oil. When the engine temperature remains low, the warm cooling water is supplied only to the engine until the cooling water temperature attains the specified value so as to make early warm-up of the engine, and after the cooling water temperature has attained the specified value, the warm cooling water is supplied to a heat-exchanger 109 to heat the transmission oil so as to warm up the transmission. In case the temperature of the transmission oil is over the second specified value, the warm cooling water is not supplied to the transmission even if the cooling water temperature is over the mentioned specified value, and the supply of the warm cooling water to the engine is continued.</p> |
