    摘要： A cooling system includes a cooling portion for flowing a coolant therethrough, a coolant sensitive sensor portion detecting a temperature of the coolant, a heat exchanging device using a heat of the coolant, a circulation flow varying device for varying a circulation flow, a circulation path for flowing the coolant therethrough, and a controller for regulating the circulation flow by controlling the circulation flow varying device while referring to the temperature of the coolant upon a receipt of a request for a requested flow from the heat exchanging device. The controller determines a condition for warming-up when the warming-up of the engine is performed in accordance with the temperature of the coolant, controls the circulation flow varying device for warming-up the engine without circulating the coolant, and increases the circulation flow to the requested flow for a predetermined period of time when the requested flow is requested during the warming-up.

    摘要： The invention relates to a cooling system in which the fan output is determined by an output control from the characteristic curves of the fan motor, the operating parameters of the cooling system and the reference input variables predetermined in the form of temperature levels. Different characteristic curves for the activation of the fan motor are here assigned to the different set temperature levels. If the reference input variable for the control changes, this also results in a change of the characteristic curves for activation of the fan motor. In order to prevent the fan motor starting to howl, in the event of a change in the reference input variable for the fan control the operation of the fan motor is kept constant for an adjustable minimum waiting time. During this minimum waiting time, switching over of the cooling circuit may have caused the operating parameters of the cooling system to adjust to the new reference input variable to such a degree that howling of the fan motor is no longer of concern.

    摘要： An electronically controlled thermostat control method is obtained which makes it possible to eliminate the response delay from the time that the required cooling water temperature is set to the time that the actual cooling water temperature reaches the set water temperature by controlling the flow rate, and to realize high cooling water temperature tracking characteristics with a high degree of precision at a low cost.The method of the present invention is characterized in that in an electronically controlled thermostat which is used to control the cooling water temperature of an engine, and which comprises an actuator that can arbitrarily vary the degree of valve opening without depending only on the actual cooling water temperature, the actuator is controlled by the control controller, which has means for calculating the elapsed time from the powering of the actuator to the variation of the water temperature for predicting the water temperature after the elapsed time when the cooling water temperature is controlled to an arbitrarily set water temperature, and the actuator is controlled in advance in accordance with the above-described predicted water temperature.

    摘要： A method for controlling an electronically controlled thermostat provided in a cooling system of an internal combustion engine includes predicting a thermal radiation amount of a radiator when a water temperature of engine cooling water is stabilized at a second set temperature or at a first set temperature without detecting the water temperature not to cause temperature hunting, when the water temperature is controlled from a first set temperature to the second set temperature lower than the first set temperature or from the second set temperature to the first set temperature. The electronically controlled thermostat is controlled in accordance with the predicted thermal radiation amount.

    摘要： A system for diagnosing operation of a cooling system for an internal combustion engine includes a coolant temperature sensor producing a temperature signal corresponding to coolant fluid temperature, means for determining either an engine load or a throttle percentage, and a control computer configured to diagnose operation of the cooling system as a function of the temperature signal, either the engine load or throttle percentage, and a fuel delivery command for controllably supplying fuel to the engine. After expiration of a diagnostic period, the control computer diagnoses the cooling system as normally operating if the diagnostic period ended by the temperature signal meeting or exceeding a predefined temperature and if a total energy used by the engine during the diagnostic period is less than an estimated energy, and diagnoses the cooling system as failing if the total energy used during the diagnostic period otherwise meets or exceeds the estimated energy.
