  • Cooling system controller for vehicle
    Patent number: 6591174
    Abstract: 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.
