These servo motors 71 to 74 are controlled to rotate by the air conditioner ECU 101, detect information such as the rotation position and rotation speed of the rotor, and feed back to the air conditioner ECU 101. Specifically, the drive circuits 131 to 134 receive the drive command signal from the air conditioner ECU 101 and drive the corresponding servo motors 71 to 74.

  As shown in FIG. 4, a rear seat duct 151 branched from a duct 28 (which may be on the driver's seat side, the passenger seat side, or on the upstream side thereof) is provided, for example, below the center console 150, Are provided with a rear-seat right face air outlet 152 which is the air outlet on the right side of the vehicle interior rear seat and a rear seat left face air outlet 153 which is the air outlet on the left side of the vehicle interior rear seat. Each air outlet is provided with a damper (152a, 153a) and an actuator (not shown) for opening and closing the air outlet.

  In addition, swing grills 45a, 46a, 152b, and 153b are attached to the driver's seat face outlet 45, the passenger seat face outlet 46, the rear seat right face outlet 152, and the rear seat left face outlet 153, respectively. (See FIGS. 3 and 4). The swing grill includes a vertical louver in which a plurality of elongated plates extending in the vehicle width direction are arranged in a row in the vehicle width direction, and a horizontal louver in which a plurality of elongated plates extending in the vehicle width direction are arranged in a row in the vehicle height direction. These louvers are swung within a predetermined range by driving a step motor in response to a command from the air conditioner ECU 101, and the direction in which the conditioned air is blown out changes from side to side or up and down. The configuration and operation of the swing grill are described in detail in, for example, Japanese Patent Application Laid-Open No. 2006-264485.

  Returning to FIG. 2, the air conditioning sensor 120 connected to the air conditioner ECU 101 includes an inside air temperature sensor 121 that detects the inside temperature of the vehicle, an outside air temperature sensor 122 that detects the outside temperature of the vehicle, and an evaporator that detects the temperature of the air immediately after passing through the evaporator. It is configured to include known sensors such as a rear sensor 123, a solar radiation sensor 124 that detects the amount of solar radiation, and a humidity sensor 125 that detects the humidity inside the vehicle.

  The air-conditioning operation unit 140 connected to the air-conditioner ECU 101 is provided on an air-conditioner panel provided in the center of the front of the instrument panel that can be operated by the driver and the passenger on the front passenger seat. It includes switches such as a switch, an air outlet changeover switch (MODE switch), an inside / outside air changeover switch, a defroster switch, an A / C switch, and an independent / collective control changeover switch (DUAL switch).

  The air conditioner ECU 101 has a known configuration including a CPU, a ROM, a RAM, and the like, and drives and controls the air conditioning drive unit 130 based on operation states of various air conditioning operation units 140 and detection results of the various air conditioning sensors 120. Thus, well-known air conditioning control such as blowout temperature control, air volume control, inside air / outside air intake switching control, and outlet switching control is executed. These air conditioning controls are executed in such a manner that the CPU of the air conditioner ECU 101 executes an air conditioning control program stored in its own ROM. The air conditioner ECU 101 corresponds to the air conditioning control unit of the present invention.

  The pre-air conditioning control process in the vehicle air conditioning system 1 will be described with reference to FIG. This process is included in the control program stored in the ROM included in the control ECU 201, and is repeatedly executed by the CPU together with other processes included in the program.

  First, the user instructs the start of pre-air conditioning by operating the operation unit 302 of the portable device 300 (S11). When pre-air conditioning start is instructed, a pre-air conditioning start instruction signal is transmitted from the RF communication device 304. When the control ECU 201 receives the pre-air conditioning start instruction signal via the RF communication device 211, the control ECU 201 determines whether the pre-air conditioning start condition is satisfied. For example, when it is determined that the vehicle is parked, it is determined that the pre-air conditioning start condition is satisfied.

Whether or not the vehicle is parked is determined using at least one of the following.
When it is determined that the door courtesy SW 212 of all the doors is in an extinguished state (that is, all the doors are closed), the parking state is determined.
When it is detected that the door lock motors 213 of all doors are locked, it is determined that the vehicle is in the parking state.
-When the state of the IG relay 214 is an off state (that is, the engine is stopped), it is determined that the vehicle is in the parking state.
-When the state of ACC relay 215 is an OFF state (namely, engine stop state), it determines with it being in a parking state.
When the shift position detected by the shift sensor 216 is the “parking” position, it is determined that the vehicle is in the parking state.
When the vehicle speed detected by the vehicle speed sensor 217 is 0 km / h, it is determined that the vehicle is parked.

  When it is determined that the pre-air conditioning start condition is satisfied (S12: Yes), a pre-air conditioning start command is transmitted to the air conditioner ECU 101 so as to start the pre-air conditioning. When receiving the pre-air-conditioning command, the air-conditioner ECU 101 drives and controls the air-conditioning drive unit 130 so as to be in an AUTO mode that is a predetermined air-conditioning mode (first pre-air-conditioning). The AUTO mode corresponds to the automatic mode of the present invention. For example, “the set temperature is 25 ° C., the face outlets of all seats: open, the air volume: automatic”.

  Next, an outlet opening / closing control process is performed when the user gets on (S14, second pre-air conditioning, details will be described later).

Next, it is determined whether or not the pre-air conditioning stop condition is satisfied. The pre-air conditioning stop condition uses at least one of the following.
When the state of the IG relay 214 is changed from the off state to the on state (that is, the engine start state), it is determined that the pre-air conditioning stop condition is satisfied.
-It is determined that the pre-air-conditioning stop condition is satisfied when a predetermined time threshold value such as 3 minutes is exceeded after the pre-air-conditioning start condition is satisfied.
-It determines with pre air conditioning stop conditions having been satisfied, when predetermined time, such as 3 minutes, has passed since the start of 1st pre air conditioning.
-It determines with pre air-conditioning stop conditions having been satisfied, when predetermined time, such as 2 minutes, has passed since the start of 2nd pre air-conditioning.
When the user operates the operation unit 302 of the portable device 300 to instruct the pre-air conditioning stop and the RF communication device 211 receives the pre-air conditioning stop instruction from the portable device 300 (RF communication device 304), the pre-air conditioning stop condition Is determined to have been established.

  When it is determined that the pre-air conditioning stop condition is satisfied (S15: Yes), a pre-air conditioning stop command is transmitted to the air conditioner ECU 101 so as to stop the pre-air conditioning (S16). When the air conditioner ECU 101 receives the pre-air-conditioning stop command, the air-conditioner ECU 101 stops driving the air-conditioning drive unit 130.

The air outlet opening / closing control process (second pre-air conditioning according to the present invention) corresponding to step S14 of FIG. 5 will be described with reference to FIG. First, the presence / absence of the user's intention to board is determined using at least one of the following (S30).
-When a door changes from a closed state to an open state, it determines with a user having a boarding intention. For example, when the door courtesy SW 212 transitions from the unlit state to the lit state, or when the door lock motor 213 operates to unlock the door, it is considered that the door has transitioned from the closed state to the open state.
When it is detected that the user has operated the door knob SW220, it is determined that the user has an intention to get on.
When it is detected that the user has approached the vehicle, it is determined that the user has an intention to board.
When configured as the above-described smart keyless entry system, it is determined that the user has an intention to get on the vehicle when the above-described collation is correctly performed through communication between the portable device 300 and one of the antennas of the door antenna group 210a.

  Since the door courtesy SW 212, the door lock motor 213, the door knob SW 220, and the door antenna are provided in each door, it is possible to specify from which door the user gets on (that is, which seat to get on).

  When it is determined that the user has an intention to board, the second pre-air conditioning is performed. That is, when the user is about to get on the D seat (S31: Yes), a command is sent to the air conditioner ECU 101 to open the driver's seat side face outlet 45 (S32). When the user is about to get on the P seat (S33: Yes), a command is sent to the air conditioner ECU 101 to open the passenger seat side face outlet 46 (S34). At this time, if the opening and closing of the two face outlets in each seat can be individually controlled by the damper, a command is sent to the air conditioner ECU 101 so that only the door side outlet is opened. Further, when the above-described swing grill (45a, 46a) is provided at each outlet, a command is sent to the air conditioner ECU 101 to adjust the angle of the swing grill so as to blow out air to the door side of each seat.

  When the user is about to get into the RR seat (S35: Yes), a command is sent to the air conditioner ECU 101 to open the rear seat right face outlet 152 (S36). When the user is about to get on the RL seat (S37: Yes), a command is sent to the air conditioner ECU 101 to open the rear seat left face outlet 153 (S38). Further, when the above-described swing grill (152b, 153b) is provided at each outlet, a command is sent to the air conditioner ECU 101 to adjust the angle of the swing grill so as to blow air to the door side of each seat.

  The air conditioner ECU 101 performs opening / closing control of each outlet based on the command sent from the control ECU 201. The air volume from the outlet may be a predetermined air volume or an air volume set based on the above-mentioned AUTO mode.

  When there is no intention of boarding from any of the doors, pre-air conditioning (first pre-air conditioning) in the AUTO mode is continued.

  With reference to FIG. 7, another example of the pre-air conditioning control process in the vehicle air conditioning system 1 will be described. Since this process is a modification of the process of FIG. 5, the same number is assigned to the same process step, and a detailed description thereof is omitted here.

  When the control ECU 201 receives a pre-air conditioning start instruction signal from the portable device 300 via the RF communication device 211 (S11), the control ECU 201 determines whether the pre-air conditioning start condition is satisfied. When it is determined that the pre-air conditioning start condition is satisfied (S12: Yes), the charging state of the battery 219 is acquired from the power supply state monitoring unit 218, and the remaining battery level (that is, charging power) is determined (S120).

  When the charging power of the battery 219 exceeds a predetermined first threshold C1 (S121: Yes), normal mode processing in pre-air conditioning is executed (S122, described later).

  The normal mode process corresponding to step S122 in FIG. 7 will be described with reference to FIG. First, air conditioning is performed in the AUTO mode as the first pre-air conditioning (S51). Since this is the same as step S13 in FIG. 5, a detailed description thereof will be omitted. Next, an outlet opening / closing control process (second pre-air conditioning) when the user gets on is executed (S52). Since this is the same as the processing of FIG. 6, a detailed description thereof is omitted here.

  The battery reduction mode 1 process corresponding to step S124 in FIG. 7 will be described with reference to FIG. First, pre-air conditioning is started in the D seat FACE mode as the first pre-air conditioning (S71). This instructs the air conditioner ECU 101 to blow out air only from the driver's seat side face outlet 45. At this time, when the above-described swing grill (45a) is provided at the driver's seat side face outlet, the air conditioner ECU is instructed to adjust the angle of the swing grill so that the air blown to the D seat (2D) is applied. Send. In addition, a command may be sent to the air conditioner ECU 101 to adjust the angle of the swing grill so that the air blown to the steering handle 8 is hit.

  Next, the air outlet opening / closing control process (second pre-air conditioning) when the user gets on is executed (S72). Since this is the same as the processing of FIG. 6, a detailed description thereof is omitted here.

  The battery reduction mode 2 process corresponding to step S126 of FIG. 7 will be described using FIG. In this process, even if the pre-air conditioning start condition is satisfied, the first pre-air conditioning is not performed, and only the air outlet opening / closing control process (second pre-air conditioning) when the user gets on is executed (S91). Since this is the same as the processing of FIG. 6, a detailed description thereof is omitted here.

  Although the embodiments of the present invention have been described above, these are merely examples, and the present invention is not limited to these embodiments, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims. Various modifications based on this are possible.
