摘要： An engine cooling system is described that uses the same actuator to adjust both fan speed and coolant pump speed based on operating conditions of the engine and vehicle. The airflow and coolant flow are thus dependent, however, they are independent from engine speed.

摘要： The present invention removes the problem conventionally confronted by electronically controlled thermostats that implementation of improved fuel consumption is difficult, and implements high cooling-water temperature controllability, improved fuel consumption, and an improvement of the heater function and so forth with high accuracy and at low cost. The electronically controlled thermostat 21 comprises a heater element, which is an actuator that can be used for cooling-water control of the engine 1 and that is capable of optionally varying the valve-opening ratio, and an engine control unit that computes a target temperature by means of various engine parameters and distributes the power distribution amount required to operate the heater element so that the cooling water temperature reaches the target temperature. The current value distributed to the heater element is determined by monitoring only the actual water temperature of the cooling water. The current value is obtained by reading the difference in the cooling-water temperature variation per unit time and then predicting the cooling-water temperature according to this difference.

摘要： Method and apparatus for controlling a cooling fan in a vehicle engine compartment, such as a tractor or combine. A fan control receives inputs from sensors and uses the sensor inputs in determining fan speeds which meet cooling needs while limiting fan energy consumption. Sensor data include at least one of PTO and transmission settings, throttle command and engine speed, and fan speed and air conditioner settings. Sensor data is received and processed in the fan control, which sends the greatest determined fan speed to a fan actuator. When the PTO is activated and the transmission is in park, fan speed can be controlled according to an alternate coolant temperature table. When throttle command is zero and engine speed is above a maximum, fan speed is set at maximum. When air conditioning is activated, fan speed is set at least at a predetermined minimum speed.

摘要： A method for cooling a motor vehicle engine consists in regulating the volume and the flow rate of a coolant fluid in a hydraulic circuit provided with a degassing bypass hose equipped with an electronically controlled proportional actuator and with means forming direct return of fluid or bypass. The method comprises a step of determining the temperature of the cooling liquid, a step of comparing the temperature of the cooling liquid with a first and second threshold temperature, and a step of controlling the opening of the actuator such that, when the fluid temperature is between the first and the second threshold temperatures, the degree at which the actuator is opened is at least temporarily proportional to the cooling fluid temperature. The invention also concerns a device for cooling a motor vehicle engine.

摘要： A cooling system controller for a vehicle includes a radiating rate measurement unit measuring the radiating rate of a radiator, a heating rate estimation unit estimating the heating rate of a heat generating device such as an engine, transmission and brake, a heat balance comparing unit calculating a heat balance error quantity by comparing the radiating rate measured by the radiating rate measuring unit with the heating rate estimation forecasted by the heating rate estimating unit, and calculating a radiating rate follow-up value in order to achieve a heat balance with the heating rate estimate, an adaptive control unit learning state changes of the radiating device and the heat generating device and adaptively-controlling the cooling system according to the heat balance comparison by the heat balance comparing unit, and a cooling fan control unit controlling the operation of a cooling fan in order to meet the radiating rate follow-up value calculated by the heat balance comparing unit. The cooling system controller is capable of improving the cooling efficiency of the radiator by maintaining the coolant temperature as high as possible, and minimizing the required power for the cooling fan by maintaining the cooling fan speed as low as possible.

摘要： A system and method of controlling airflow within an air delivery system. The method begins by identifying and measuring a particular air conditioning system's blower characteristics. A mathematical relationship for finding a particular CFM based on torque and speed is developed utilizing several discrete airflows within regions or bins within a designated range. The mathematical model is employed by a controller of the air conditioning system for controlling CFM. Additionally, the method may optionally change from an airflow control mode to a blower speed or torque control mode when restrictions are placed upon the air conditioning system.
