  • COOLING FAN CONTROL METHOD FOR VEHICLE
    Publication number: 20190168568
    Abstract: A cooling fan control method for a vehicle is provided. The method includes turning on a starting of the vehicle and sensing a stack temperature. A first required speed of first and second cooling fans required by the stack radiator is set and a temperature of an electrical equipment is sensed to set a second required speed of the first cooling fan. When an air conditioner is operated; an air conditioner pressure is sensed and a second required speed of the second cooling fan required by the condenser is set. The method then compares the required speeds as well as a resonance frequency RPM to determine different setting conditions of the fans. The operation of the fans is complete when the coolant temperature and an air conditioner pressure of the stack and the electrical equipment are within a predetermined setting value.
