方法および装置を提供することにある。However, the conventional oil temperature control of the above-described transmission is a control based on only the oil temperature.
Depending on the relationship between the temperature of the engine cooling water and the temperature of the oil from the automatic transmission, bypassing the oil cooler may delay warm-up of the automatic transmission, resulting in poor transmission efficiency and poor fuel economy. is there. Also, in conventional oil temperature control of a general transmission, when traveling at light load and high speed, the traveling wind promotes cooling at the radiator, the degree of opening of the thermostat is small, and the flow rate of the radiator circulating cooling water is reduced. The surrounding water temperature becomes low, the temperature of the transmission becomes lower than the appropriate temperature, the viscosity of the oil becomes high, and the operation is performed with low transmission efficiency, which may lead to deterioration of fuel efficiency. An object of the present invention is to provide an oil temperature control method and apparatus capable of improving efficiency of a lubricated machine (for example, a transmission) and suppressing deterioration of fuel efficiency by controlling an engine cooling water side.

の悪化が防止される。In the oil temperature control methods of (1) and (2) and the oil temperature control devices of (3) and (4), the temperature of the cooling water around the oil heat exchanger in the oil heat exchanger arrangement portion is reduced. Since the temperature is controlled based on the vehicle operating condition, the temperature of the cooling water around the oil heat exchanger is prevented from rising or almost falling, so that even if the oil is circulated through the oil heat exchanger, The temperature does not decrease, the oil viscosity does not increase, and the efficiency of the lubricated machine does not decrease, thereby preventing deterioration of fuel efficiency. In particular, during engine warm-up, the temperature of the engine cooling water around the oil heat exchanger rises by circulating the cooling water from the engine, which is rising in temperature, around the oil heat exchanger, thereby increasing the oil temperature. In addition, warming up of the lubricated machine can be promoted. If the temperature of the cooling water in the radiator drops excessively due to the wind during running at light load and high speed after the engine is warmed up, either prevent the engine cooling water from flowing around the oil heat exchanger or allow the engine cooling water to be excessive at the radiator. By preventing the temperature of the engine cooling water around the oil heat exchanger from becoming too low, the oil viscosity is prevented from increasing and the efficiency of the lubricated machine is prevented from lowering, and deterioration in fuel efficiency is prevented.

Also, when the radiator body cooling water temperature control means is provided in the oil heat exchanger arrangement portion and comprises a partition which can be opened and closed according to the water temperature, when the engine is warmed up at a light load at a high speed, the radiator Even if the internal cooling water temperature is excessively lowered, the water cooled by the radiator does not hit the oil heat exchanger by the partition. As a result, the oil heat exchanger is not excessively cooled by cold water, the oil temperature can be appropriately maintained, the oil viscosity does not increase and the transmission efficiency does not decrease, and deterioration of fuel efficiency is prevented. Further, when the radiator body cooling water temperature control means comprises a shutter, the shutter operates during light load high-speed running after the engine is warmed up,
The cooling wind in the radiator is prevented from being excessively lowered by the traveling wind. As a result, the oil heat exchanger is not excessively cooled by cold water, the oil temperature can be appropriately maintained, the oil viscosity does not increase and the transmission efficiency does not decrease, and deterioration of fuel efficiency is prevented. In the oil temperature control method of the above (10) and the oil temperature control device of the above (11), the temperature of the engine cooling water around the transmission oil heat exchanger in the transmission oil heat exchanger arrangement portion is prevented from rising or almost falling. Therefore, even if the transmission oil is circulated through the transmission oil heat exchanger, the oil temperature does not decrease due to the engine cooling water, the oil viscosity does not increase and the transmission efficiency does not decrease, and deterioration in fuel efficiency is prevented. You. In particular, during warming-up of the engine, the temperature of the engine coolant around the transmission oil heat exchanger rises by circulating the rising coolant from the engine around the transmission oil heat exchanger, thereby increasing the oil temperature. And the warm-up of the transmission can be promoted. If the cooling water temperature inside the radiator drops excessively due to the wind during running at light load and high speed after the engine is warmed up, either prevent the flow of the engine cooling water around the transmission oil heat exchanger or allow the radiator to cool the engine cooling water. By preventing the temperature of the engine cooling water around the transmission oil heat exchanger from becoming excessively low, the oil viscosity is prevented from decreasing and the transmission efficiency is reduced, and the deterioration of fuel efficiency is suppressed. Is prevented. In the oil temperature control device of the above (12), since the engine cooling water temperature control means around the transmission oil heat exchanger comprises the third engine cooling water inlet / outlet and the partition, during engine warm-up, from the engine or from the engine. From the heater through the heater to the transmission oil heat exchanger placement area, and also suppresses mixing of hot and cold water in the radiator, and positively raises the engine cooling water temperature around the transmission oil heat exchanger. The transmission can be quickly warmed up. In the oil temperature control device of the above (13), the engine cooling water temperature control means around the transmission oil heat exchanger includes the third engine cooling water inlet / outlet and a valve or a thermostat. Hot water from the engine via the heater can flow to the transmission oil heat exchanger arrangement portion, the engine cooling water temperature around the transmission oil heat exchanger can be positively increased, and the transmission can be quickly warmed up. In the oil temperature control device of the above (14), the engine cooling water temperature control means around the transmission oil heat exchanger comprises a partition provided in the transmission oil heat exchanger arrangement portion and capable of opening and closing according to the water temperature. Even when the cooling water temperature in the radiator is excessively lowered by the traveling wind during light-load high-speed running after the warm-up, the water cooled by the radiator does not hit the transmission oil heat exchanger due to the partition. As a result, the transmission oil heat exchanger is not excessively cooled by cold water, the oil temperature can be maintained properly, the oil viscosity does not increase and the transmission efficiency does not decrease, and deterioration of fuel efficiency is prevented. . In the oil temperature control device of the above (15), since the engine cooling water temperature control means around the transmission oil heat exchanger comprises a shutter, the shutter operates during light load high-speed running after the engine is warmed up, and the inside of the radiator is cooled by running wind. The water temperature is prevented from dropping excessively.
As a result, the transmission oil heat exchanger is not excessively cooled by cold water, the oil temperature can be maintained properly, the oil viscosity does not increase and the transmission efficiency does not decrease, and deterioration of fuel efficiency is prevented. .

が防止される。According to the oil temperature control method of the first and second aspects and the oil temperature control apparatus of the third and fourth aspects, the temperature of the cooling water around the oil heat exchanger in the oil heat exchanger arrangement portion is controlled by the vehicle operation. Since the temperature is controlled based on the state, by keeping the temperature of the cooling water around the oil heat exchanger from rising or hardly falling, even if the oil is circulated through the oil heat exchanger, the oil temperature will be reduced by the cooling water. The oil viscosity does not decrease, the efficiency of the lubricated machine does not decrease, and the deterioration of fuel efficiency is prevented. In particular, during engine warm-up, the temperature of the engine cooling water around the oil heat exchanger rises by circulating the cooling water from the engine, which is rising in temperature, around the oil heat exchanger, thereby increasing the oil temperature. In addition, warming up of the lubricated machine can be promoted. If the temperature of the cooling water in the radiator drops excessively due to the wind during running at light load and high speed after the engine is warmed up, either prevent the engine cooling water from flowing around the oil heat exchanger or allow the engine cooling water to be excessive at the radiator. So that it does not get cold

As a result, the oil heat exchanger is not excessively cooled by cold water, the oil temperature can be appropriately maintained, the oil viscosity does not increase and the transmission efficiency does not decrease, and deterioration of fuel efficiency is prevented. Further, when the radiator body cooling water temperature control means includes a shutter, the shutter operates during light-load high-speed running after the engine is warmed up, thereby preventing the cooling water temperature in the radiator from being excessively lowered by the running wind. As a result, the oil heat exchanger is not excessively cooled by cold water, the oil temperature can be appropriately maintained, the oil viscosity does not increase and the transmission efficiency does not decrease, and deterioration of fuel efficiency is prevented. According to the transmission oil temperature control method of the tenth aspect and the transmission oil temperature control apparatus of the eleventh aspect, the temperature of the engine cooling water around the transmission oil heat exchanger in the transmission oil heat exchanger arrangement portion rises or hardly decreases. Therefore, even if the transmission oil is circulated through the transmission oil heat exchanger, the oil temperature does not decrease due to the engine cooling water, the oil viscosity does not increase, and the transmission efficiency does not decrease. Is prevented. In particular, during warming-up of the engine, the temperature of the engine coolant around the transmission oil heat exchanger rises by circulating the rising coolant from the engine around the transmission oil heat exchanger, thereby increasing the oil temperature. And the warm-up of the transmission can be promoted. If the cooling water temperature inside the radiator drops excessively due to the wind during running at light load and high speed after the engine is warmed up, either prevent the flow of the engine cooling water around the transmission oil heat exchanger or allow the radiator to cool the engine cooling water. By preventing excessive cooling and keeping the temperature of the engine cooling water around the transmission oil heat exchanger from lowering, it is possible to prevent the oil viscosity from increasing and the transmission efficiency from lowering, thereby preventing fuel efficiency from deteriorating. Is done. According to the transmission oil temperature control device of the twelfth aspect, since the engine cooling water temperature control means around the transmission oil heat exchanger comprises the third engine cooling water inlet / outlet and the partition, during engine warm-up, Alternatively, hot water from the engine via the heater can be put into the transmission oil heat exchanger placement section, and mixing of hot and cold water in the radiator can be suppressed, and the engine cooling water temperature around the transmission oil heat exchanger can be positively increased. And the transmission can be quickly warmed up. According to the transmission oil temperature control device of the thirteenth aspect, the engine cooling water temperature control means around the transmission oil heat exchanger includes the third engine cooling water inlet / outlet and a valve or a thermostat. Or, the hot water from the engine via the heater can flow to the transmission oil heat exchanger arrangement portion, the engine cooling water temperature around the transmission oil heat exchanger can be positively increased, and the transmission can be quickly warmed up. . According to the transmission oil temperature control device of the fourteenth aspect, the engine oil cooling water temperature control means around the transmission oil heat exchanger is formed of a partition provided in the transmission oil heat exchanger arrangement portion and capable of opening and closing according to the water temperature. In addition, even when the cooling water temperature in the radiator is excessively lowered by the traveling wind during high-speed running under light load after the engine is warmed up, the water cooled by the radiator does not hit the transmission oil heat exchanger due to the partition. as a result,
