Description

  The present invention relates to a vehicle control module that controls an electric device provided in a vehicle.

  As this type of vehicle control module, for example, a control device included in a construction machine described in Patent Document 1 is conventionally known. In the construction machine, which is a vehicle described in Patent Document 1, a radiator and an oil cooler are separately arranged with respect to the engine of the construction machine, and these are cooled by blowing air from a cooling fan.

  The oil cooler is installed on the downstream side of the radiator with respect to the air flow generated when the cooling fan is reversely rotated. Further, the cooling fan stops, rotates normally, or reverses when a hydraulic motor connected to the cooling fan is controlled by an electromagnetic switching valve of the fan drive circuit. The electromagnetic switching valve is automatically switched by a control device having a plurality of temperature sensors.

  In the construction machine configured as described above, the control device corresponding to the vehicle control module reverses the cooling fan when the coolant temperature is equal to or higher than the set temperature and the hydraulic oil temperature is lower than the set temperature. As a result, the working oil in the oil cooler is warmed by the warm air that has passed through the radiator, and dust that is clogged in the radiator and the like is discharged by the reverse wind.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following embodiments including other embodiments described later, the same or equivalent parts are denoted by the same reference numerals in the drawings.

(First embodiment)
FIG. 1 is a schematic diagram illustrating a schematic configuration of an airflow management system 10 in the present embodiment. FIG. 1 is a view of the engine room 14 viewed from the left side toward the front of the vehicle. Further, arrows DRx and DRy in FIG. 1 indicate the direction of the vehicle on which the airflow management system 10 is mounted. That is, the double-ended arrow DRx in FIG. 1 indicates the vehicle longitudinal direction DRx, and the double-ended arrow DRy indicates the vehicle vertical direction DRy.

  The airflow management system 10 in FIG. 1 is a system that controls the air flow in the engine room 14, and is provided in the engine room 14.

  The engine room 14 is a space in which the engine 12 as a driving power source for traveling is arranged, and is a front engine room provided in front of the vehicle with respect to the passenger compartment (that is, the vehicle compartment) of the vehicle. The engine room 14 is opened to the outside of the engine room 14 so that traveling wind flows in front of the vehicle in the engine room 14.

  As shown in FIG. 1, the airflow management system 10 includes a main fan 16, a main fan motor 18, an air guide duct 20, a subfan 22, a subfan motor 24, a shutter 26, a shutter motor 28, and a temperature sensor 30. And a vehicle control module 32 (hereinafter referred to as a control module 32).

  The main fan 16 is, for example, an axial flow type fan, and is provided in the engine room 14. Specifically, the main fan 16 is disposed in the engine room 14 at the front of the vehicle with respect to the engine 12, and is disposed at the rear of the vehicle with respect to the condenser 34 and the radiator 36. That is, the condenser 34, the radiator 36, and the main fan 16 are arranged in the order of the condenser 34, the radiator 36, and the main fan 16 from the front of the vehicle.

  The condenser 34 is a constituent element of an air conditioner that air-conditions the passenger compartment. The condenser 34 includes a refrigeration cycle apparatus that circulates refrigerant contained in the air conditioner together with a compressor, a pressure reducing valve, and an evaporator. In detail, the capacitor | condenser 34 is an outdoor heat exchanger as a heat radiator which radiates the heat | fever of the high pressure refrigerant | coolant discharged from a compressor to outside air, and condenses the high pressure refrigerant | coolant.

  The radiator 36 is an engine cooling heat exchanger for cooling the engine 12. Specifically, the radiator 36 cools the engine 12 by dissipating heat of engine cooling water as a heat medium circulating in the engine 12 to the outside air.

  Air passing through the condenser 34 and the radiator 36 is guided to the main fan 16 by a shroud (not shown). The main fan 16 generates an airflow passing through the condenser 34 and the radiator 36 as the main fan 16 rotates.

  The main fan motor 18 is connected to the main fan 16 and rotates the main fan 16. Specifically, the main fan motor 18 is a three-phase brushless motor. The main fan motor 18 rotates the main fan 16 in either the forward direction or the reverse direction in accordance with a control signal from the control module 32. The main fan motor 18 is a motor that detects the rotor position so that the main fan motor 18 itself can be switched between forward rotation and reverse rotation. The normal rotation of the main fan 16 is a rotation direction in which the main fan 16 blows air from the front of the vehicle toward the rear of the vehicle. On the other hand, the reverse rotation of the main fan 16 is a rotation direction in which the main fan 16 blows air from the rear of the vehicle toward the front of the vehicle.

  The air guide duct 20 is an air guide pipe that guides air from the front of the engine 12 to the rear of the engine 12 in the engine room 14. In order to guide the air in this way, the front opening 201 which is one opening end portion of the air guide duct 20 is formed in, for example, a shroud that guides air from the radiator 36 to the main fan 16, and in the air flow of the shroud An opening is provided between the radiator 36 and the main fan 16. On the other hand, the rear opening 202 which is the other opening end of the air guide duct 20 is opened behind the engine 12. Further, the air guide duct 20 is disposed so as to pass through, for example, the upper side of the engine 12 in the engine room 14.

  The sub fan 22 is, for example, an axial flow type fan, and is disposed in the front opening 201 of the air guide duct 20. The sub fan 22 blows air through a wind guide duct 20 to a predetermined position in the engine room 14, that is, to the rear of the engine 12. That is, unlike the main fan 16, the sub fan 22 rotates in one direction, and blows air from the front of the vehicle toward the rear of the vehicle by rotating in the one direction.

  The sub fan motor 24 is connected to the sub fan 22 and rotates the sub fan 22 in one direction in accordance with a control signal from the control module 32. Specifically, the sub fan motor 24 is configured by a brushless motor. The sub fan motor 24 is a position sensorless motor (that is, a position sensorless brushless motor) in which the rotational position of the motor rotor is not detected by the position sensor. For example, in a positionless sensorless brushless motor, the rotational position of the motor rotor is estimated by a known method based on the motor voltage and current.

  The temperature sensor 30 detects the temperature in the engine room 14. For example, the temperature sensor 30 is provided at the rear opening 202 of the air guide duct 20 or in the vicinity thereof, and detects the temperature behind the engine 12 in the engine room 14. Detection signals from the temperature sensor 30 are sequentially sent to the control module 32.

  The shutter 26 is an opening / closing device that blocks an air flow flowing into the engine room 14 from the front of the vehicle. The shutter 26 is disposed in front of the vehicle with respect to the condenser 34 in the engine room 14. When the shutter 26 is opened, air can flow into the engine room 14 from the front of the vehicle, and when the shutter 26 is closed, air is prevented from flowing into the engine room 14 from the front of the vehicle.

  The shutter motor 28 is connected to the shutter 26 and opens and closes the shutter 26 in accordance with a control signal from the control module 32. Specifically, the shutter motor 28 is a stepping motor. Since it is assumed that the shutter 26 is locked due to, for example, freezing due to snow or foreign object pinching, the shutter motor 28 is composed of a stepping motor (in other words, a stepper motor). That is, the shutter motor 28 which is a stepping motor is configured to prevent mechanical damage to the shutter 26 by stepping out when the shutter 26 is locked.

The input filter 44 distributes the power supplied from the battery to the input circuit 40, the communication circuit 42, the central processing unit 46, and the control circuits 48, 50, 52. At that time, the input filter 44 removes power supply noise. A power supply circuit (not shown) is provided between the input filter 44 and the communication circuit 42 and the central processing unit 46, and the power supply circuit is connected to the communication circuit 42 and the central processing unit for the output voltage of the input filter 44.

  For example, the main fan motor control circuit 48 drives or stops the main fan motor 18 in accordance with a command signal from the CPU 46. When the main fan motor control circuit 48 drives the main fan motor 18, the main fan motor control circuit 48 controls the direction of rotation of the main fan motor 18 (that is, normal rotation and reverse rotation) in accordance with the command signal, and the number of rotations is also controlled. Control.

  The sub fan motor control circuit 50 is connected to the sub fan motor 24 via an electric wire and is installed away from the sub fan motor 24. The sub fan motor control circuit 50 is an electric circuit that functions as a sub motor drive unit that drives the sub fan motor 24.

  The sub fan motor control circuit 50 drives or stops the sub fan motor 24 according to a command signal from the CPU 46, for example. Further, when the main fan motor 18 is driven, the sub fan motor control circuit 50 controls the rotation speed of the sub fan motor 24 in accordance with the command signal.

  The shutter motor control circuit 52 is connected to the shutter motor 28 via an electric wire and is installed away from the shutter motor 28. The shutter motor control circuit 52 is an electric circuit that functions as a shutter motor driving unit that drives the shutter motor 28.

  The shutter motor control circuit 52 drives or stops the shutter motor 28 in accordance with a command signal from the CPU 46, for example. Specifically, the shutter motor control circuit 52 controls the rotation direction and the rotation amount of the shutter motor 28 according to the command signal.

  The module case 54 forms the outer shell of the control module 32. As shown in FIG. 2, the module case 54 houses the input circuit 40, the communication circuit 42, the input filter 44, the CPU 46, the main fan motor control circuit 48, the sub fan motor control circuit 50, and the shutter motor control circuit 52. ing.

The module case 54 houses a main fan motor control circuit 48, a sub fan motor control circuit 50, and a shutter motor control circuit 52. Therefore, each control circuit 48, 50, and 52 does not need to be individually provided with a structure required in the engine room 14, such as a heat resistant structure, a waterproof structure, and a vibration resistant structure. Therefore, it is possible to suppress an increase in the number of components due to the provision of other control circuits 50 and 52 in addition to the main fan motor control circuit 48.
