- the vehicle operation signal determination unit 84 determines whether or not a vehicle operation signal (i.e., a signal to rotate the rotor 26 of the fan motor 22) output from an ECU (Electronic Control Unit, not shown) mounted on the vehicle has been input to the CPU 74.
- the vehicle operation signal is output from the ECU, for example, when the temperature of the radiator 14 rises and reaches a specified temperature.
- the vehicle operation signal may be output from the ECU at a predetermined fixed time interval.
- the vehicle operation signal may also be output from the ECU, for example, when raindrops are detected by a rain sensor (not shown).
- the vehicle operation signal may also be output from the ECU when the water level detected by a water level sensor (not shown) provided around the fan motor 22 rises and reaches a specified water level.
- the motor trial operation control unit 86 trial operates (i.e., performs a trial run) the fan motor 22 when the vehicle operation signal determination unit 84 determines that a vehicle operation signal has been input to the CPU 74.
- the rotation speed of the fan motor 22 when trial operating the fan motor 22 may be set to the rotation speed when the fan motor 22 is normally operated (hereinafter referred to as the "normal rotation speed") as described below, or may be set to a rotation speed lower than the normal rotation speed.
- the abnormality determination unit 88 determines whether or not there is an abnormality in the fan motor 22 based on the current value and rotation speed of the fan motor 22. Specifically, the abnormality determination unit 88 first determines whether or not the current value supplied to the stator 28 exceeds a predetermined reference current value (i.e., whether or not there is an overcurrent).
- the reference current value is set, for example, to the upper limit of the current value when the fan motor 22 is operating normally without any foreign matter entering the inside of the fan motor 22 or the fan motor 22 being submerged in water.
- the abnormality determination unit 88 determines whether the current value supplied to the stator 28 exceeds the reference current value, it determines whether the rotation speed of the fan motor 22 is equal to or higher than a specified rotation speed.
- the specified rotation speed is set to a rotation speed higher than the rotation speed (e.g., zero rotation speed) in a state in which the rotor 26 is locked due to the intrusion of a foreign object into the fan motor 22, for example.
- the rotation speed of the fan motor 22 will be greater than or equal to the specified rotation speed. Therefore, it is possible to determine whether the rotor 26 is locked or whether the fan motor 22 is submerged based on the rotation speed of the fan motor 22.
- the abnormality determination unit 88 determines that the fan motor 22 is submerged. On the other hand, if the current value supplied to the stator 28 exceeds the reference current value but the rotation speed of the fan motor 22 is not equal to or greater than the specified rotation speed, the abnormality determination unit 88 determines that the rotor 26 is locked.
- the motor stop control unit 90 stops the fan motor 22 if the abnormality determination unit 88 determines that the fan motor 22 is submerged in water.
- the motor stop control unit 90 also stops the fan motor 22 if the abnormality determination unit 88 determines that the rotor 26 is locked.
- the specified time determination unit 92 determines whether the time that has elapsed since the fan motor 22 was stopped by the motor stop control unit 90 (hereinafter referred to as the "elapsed time") has exceeded a predetermined specified time.
- the specified time is set, for example, to the time required from when the fan motor 22 is no longer submerged in water until water drainage from the inside of the fan motor 22 is completed when the fan motor 22 is no longer submerged in water. Even if the fan motor 22 is no longer submerged in water, water will remain inside the fan motor 22 if the elapsed time is within the specified time. On the other hand, if the elapsed time exceeds the specified time after the fan motor 22 is no longer submerged in water, water drainage from the inside of the fan motor 22 will be completed.
- the motor trial control unit 86 again trials the fan motor 22 when the specified time determination unit 92 determines that the elapsed time has exceeded the specified time. Even if the fan motor 22 is submerged, if the elapsed time exceeds the specified time after the submersion of the fan motor 22 is resolved, water is discharged from inside the fan motor 22. Therefore, when water is discharged from inside the fan motor 22, the current value supplied to the stator 28 is equal to or less than the reference current value if the rotor 26 is not locked (i.e., there is no abnormality in the fan motor 22). In this case, the abnormality determination unit 88 determines that the current value supplied to the stator 28 does not exceed the reference current value (i.e., the fan motor 22 is no longer submerged).
- the submersion history determination unit 94 determines whether there is a history of the fan motor 22 being submerged in water in the most recent determination process by the abnormality determination unit 88.
- the history of the abnormality determination unit 88 determining that the fan motor 22 is submerged in water is stored in the RAM 78, for example.
- the motor operation control unit 96 operates the fan motor 22 for a predetermined specified time.
- FIG. 4 shows an example of how water droplets 100 attached to the rotor 26 are scattered by the centrifugal force of the rotor 26.
- the specified time is set, for example, to the time required for the water droplets 100 attached to the rotor 26 of the fan motor 22 to be scattered by the centrifugal force of the rotor 26.
- a water scattering operation is performed on the fan motor 22 to scatter the water droplets 100 attached to the rotor 26 by the centrifugal force of the rotor 26.
- the rotation speed of the fan motor 22 when the water scattering operation is performed may be set, for example, to the upper limit value of the rated rotation speed of the fan motor 22.
- the motor operation control unit 96 stops the fan motor 22 after operating it for the specified time.
- the motor operation control unit 96 starts operation of the fan motor 22 at the rotation speed specified by the vehicle operation signal. This causes the fan motor 22 to perform an air blowing operation in the air blowing mode. The air blowing operation is performed, for example, until a motor stop signal is input from the ECU to the CPU 74.
- step ST10 the vehicle operation signal determination unit 84 determines whether or not a vehicle operation signal output from an ECU mounted on the vehicle has been input to the CPU 74. If a vehicle operation signal has been input to the CPU 74 in step ST10, the determination is positive, and the motor control process proceeds to step ST12. If a vehicle operation signal has not been input to the CPU 74 in step ST10, the determination is negative, and the motor control process executes the process of step ST10 again.
- step ST12 the motor trial operation control unit 86 trial operates the fan motor 22. After the processing of step ST12 is executed, the motor control processing proceeds to step ST14.
- step ST14 the abnormality determination unit 88 determines whether the current value supplied to the stator 28 exceeds the reference current value (i.e., whether there is an overcurrent). If the current value supplied to the stator 28 exceeds the reference current value in step ST14, the determination is affirmative, and the motor control process proceeds to step ST16. If the current value supplied to the stator 28 does not exceed the reference current value in step ST14, the determination is negative, and the motor control process proceeds to step ST24.
- the reference current value i.e., whether there is an overcurrent
- step ST16 the abnormality determination unit 88 determines whether the rotation speed of the fan motor 22 is equal to or greater than a specified rotation speed. If the rotation speed of the fan motor 22 is equal to or greater than the specified rotation speed in step ST16, the determination is affirmative, and the motor control process proceeds to step ST18. If the rotation speed of the fan motor 22 is not equal to or greater than the specified rotation speed in step ST16, the determination is negative, and the motor control process proceeds to step ST20.
- step ST18 the motor stop control unit 90 stops the fan motor 22. After the processing of step ST18 is executed, the motor control processing proceeds to step ST22.
- step ST20 the motor stop control unit 90 stops the fan motor 22. After the processing of step ST20 is executed, the motor control processing proceeds to step ST22.
- step ST22 the specified time determination unit 92 determines whether the time that has elapsed since the fan motor 22 was stopped by the motor stop control unit 90 has exceeded the specified time. If the elapsed time has exceeded the specified time in step ST22, the determination is affirmative, and the motor control process proceeds to step ST12. If the elapsed time has not exceeded the specified time in step ST22, the determination is negative, and the motor control process executes the process of step ST22 again.
- step ST24 the submersion history determination unit 94 determines whether or not there is a history of the fan motor 22 being determined to be submerged in water by the most recent determination process by the abnormality determination unit 88. If there is a history of the fan motor 22 being determined to be submerged in water in step ST24, the determination is affirmative, and the motor control process proceeds to step ST26. If there is no history of the fan motor 22 being determined to be submerged in water in step ST24, the determination is negative, and the motor control process proceeds to step ST28.
- step ST26 the motor operation control unit 96 operates the fan motor 22 for a specified time. As a result, the water droplets 100 adhering to the rotor 26 are scattered by the centrifugal force of the rotor 26. The motor operation control unit 96 stops the fan motor 22 after operating it for the specified time. After the processing of step ST26 is executed, the motor control processing proceeds to step ST30.
- step ST28 the motor operation control unit 96 starts operation of the fan motor 22 at the rotation speed specified by the vehicle operation signal. This causes the fan motor 22 to perform air blowing operation in the air blowing mode. After the processing of step ST28 is performed, the motor control processing proceeds to step ST30.
- step ST30 the CPU 74 determines whether a condition for terminating the motor control process (i.e., a termination condition) is met.
- a termination condition is a condition in which a motor stop signal is input from the ECU to the CPU 74. If a motor stop signal is input to the CPU 74 while the fan motor 22 is operating, the operation of the fan motor 22 is stopped. If the termination condition is not met in step ST30, the determination is negative, and the motor control process proceeds to step ST14. If the termination condition is met in step ST30, the determination is positive, and the motor control process ends.
- the CPU 74 determines whether the fan motor 22 is submerged, and if it determines that the fan motor 22 is submerged (step ST16: YES), it operates the fan motor 22 (step ST26) after the fan motor 22 is no longer submerged (step ST14: NO). This makes it possible to prevent water droplets from remaining inside the fan motor 22 after the fan motor 22 is no longer submerged.
- the CPU 74 also determines whether the fan motor 22 is submerged based on the current value and rotation speed of the fan motor 22. Therefore, for example, it is possible to determine whether the fan motor 22 is submerged without using a water level sensor, etc., and therefore the number of parts can be reduced compared to when a water level sensor, etc. is used.
- step ST14 NO
- the CPU 74 operates the fan motor 22 until the water droplets 100 adhering to the rotor 26 of the fan motor 22 are scattered (step ST26). Therefore, by scattering the water droplets 100 adhering to the rotor 26, it is possible to prevent the water droplets 100 from remaining inside the fan motor 22.
- the object to be cooled by the fan 24 is, as an example, the radiator 14, but it may be something other than the radiator 14.
- the object to be cooled may be a condenser of an air conditioner, a battery of a hybrid vehicle (HV), or a battery of an electric vehicle (EV), etc.
- the cooling system 10 is applied to a vehicle such as a passenger car, but may also be applied to a special vehicle such as an amphibious vehicle.
- control circuit 34 is provided in the fan motor 22, but it may be provided separately from the fan motor 22.
- the control circuit 34 may be part or all of the ECU.
- control circuit 34 includes a computer 72 including a CPU 74, a ROM 76, and a RAM 78, but instead of the computer 72, a device including an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), and/or a PLD (Programmable Logic Device) may be applied. Also, instead of the computer 72, a combination of a hardware configuration and a software configuration may be applied.
