  By the way, after the driver of the vehicle goes to the destination to send the second party, such as a family, to the destination, the second person gets on the vehicle in which the driver is on board. When the second person who gets into the vehicle feels heat or cold, the second person must switch the seat air conditioner or main air conditioner to an air conditioning mode that makes the second person comfortable. There was a problem that the switching operation was troublesome. In addition, since the air conditioning mode for the second party is switched after the second person gets in, it takes time until the effect of the air conditioning mode can be realized, and the second person cannot feel comfort immediately after boarding. .

  A method of detecting the second person's seating position with a seating sensor or the like and automatically switching to an air conditioning mode that is optimal for the detected seating position region is also conceivable. However, with this method, the troublesome operation of switching the air-conditioning mode can be eliminated, but there still remains a problem that it takes time until the second party feels comfortable.

  In addition, the pre-air-conditioning technology described in Patent Literature 1 and the like solves the above-described problem because it assumes air-conditioning in a scene where no one is on the vehicle, that is, air-conditioning before the driver gets on the vehicle. It is not possible.

  The present invention has been made in view of the above problems, and a second person who gets into the vehicle on which the driver is on board feels comfort immediately after boarding without having to switch the air-conditioning mode himself. It is an object of the present invention to provide a vehicular air conditioning system that can be used.

In order to solve the above-mentioned problem, in the vehicle air conditioning system of the present invention, a second party other than the driver of the vehicle is approaching the vehicle in order to get on the vehicle stopped by the driver. Proximity detection means for detecting
When the approach detection means detects the approach of the second party, air conditioning means for air conditioning the vehicle interior in an air conditioning mode for the purpose of improving the comfort of the second party;
It is characterized by providing.

  According to the present invention, when it is detected that the second person is approaching the vehicle on which the driver is on board, the vehicle interior is air-conditioned in the air conditioning mode for the purpose of improving the comfort of the second party. Therefore, the air conditioning mode for the second party can be switched in advance before the second party gets into the vehicle. Therefore, the second party does not need to switch to the air-conditioning mode, and when the second person gets in, the air-conditioning mode for the second party is already in operation. You can feel comfortable immediately after boarding.

FIG. It is a block diagram of the sheet | seat air conditioner. It is a flowchart of the process in the scene which goes to send a second party. It is a flowchart of the process in the scene which goes picking up a second party.

  Hereinafter, an embodiment of a vehicle air-conditioning system according to the present invention will be described with reference to the drawings. FIG. 1 shows a configuration of a vehicle air-conditioning system 1 according to the present embodiment. The vehicle air-conditioning system 1 performs two-way communication between a vehicle-side device and an electronic key, and an electronic key system 2 (so-called smart entry system) that permits locking / unlocking of the door lock and engine starting based on the communication result. And a main air conditioner 7 that performs comprehensive air conditioning in the passenger compartment and a seat air conditioner 8 that is provided for each seat of the vehicle and performs local air conditioning on the area of each seat.

  First, the electronic key system 2 will be described. The electronic key system 2 includes, as a vehicle side device, a vehicle interior transmitter 42, a vehicle exterior transmitter 43, a tuner 44, a push switch 45, a door ECU 46, an engine ECU 47, seating sensors 61 to 64, and a verification ECU 4 to which they are connected. I have. The electronic key system 2 also includes a master key 31 carried by the driver and a spare key 32 carried by a second party other than the driver as electronic keys.

  The vehicle interior transmitter 42 transmits a request signal for confirming the presence or absence of the electronic keys 31 and 32 to an area covering the vehicle interior. As shown in FIG. 2, the outside-vehicle transmitter 43 is provided for each door of the vehicle 100, and each vehicle has an area outside the vehicle (for example, an area of about several meters from each door), that is, around the vehicle 100. Send the request signal to the area. The request signal is, for example, an LF radio wave (eg, a 134 kHz radio wave).

  The tuner 44 receives radio waves (for example, radio waves in the RF band (300 to 400 MHz band)) of the response signal transmitted from the electronic keys 31 and 32 in response to the request signal, demodulates the response signal, and collates the ECU 4. Output to. The push switch 45 is provided on an instrument panel of the vehicle 100 (see FIG. 2), and is a switch for instructing to turn on an accessory power source and an ignition power source and instructing an engine start and an engine stop. An operation signal of the push switch 45 is input to the verification ECU 4. The door ECU 46 is an ECU that controls the locking and unlocking of each door. The engine ECU 47 is an ECU that controls the engine. The ECUs 4, 46, and 47 are connected to each other so as to be able to communicate with each other through an in-vehicle LAN or direct connection (direct line).

  The seating sensors 61 to 64 are sensors that are provided for each seat and detect seating on each seat. That is, as shown in FIG. 2, the seating sensor 61 provided in the driver's seat 101 detects the seating in the driver's seat 101, and the seating sensor 62 provided in the passenger's seat 102 detects the seating in the passenger's seat 102. The seat sensor 63 provided on the right rear seat 103 detects the seating on the right rear seat 103, and the seat sensor 64 provided on the left rear seat 104 detects the seating on the left rear seat 104. The seating sensors 61 to 64 are load sensors that detect loads on the seating surfaces of the seats 101 to 104, or infrared sensors (matrix IR sensors) that detect the temperature distribution of the areas of the seats 101 to 104. , Or a sensor that detects the presence or absence of a seat belt provided in each of the seats 101 to 104.

  The verification ECU 4 includes a CPU, a ROM, a RAM, and the like, and executes various processes related to the smart entry system. Specifically, the verification ECU 4 causes the outside transmitter 43 to intermittently transmit a request signal when the vehicle 100 is parked. Thereafter, when the response signal from the electronic keys 31 and 32 is received via the tuner 44, the verification ECU 4 uses the ID code included in the response signal and the ID code stored in its own memory 41. Match. When the collation is possible, the collation ECU 4 instructs the door ECU 46 to permit the door to be locked or unlocked.

  Further, when the push switch 45 is operated, the verification ECU 4 transmits a request signal to the vehicle interior by the vehicle interior transmitter 42 in order to confirm whether or not the electronic keys 31 and 32 are present in the vehicle interior. . After that, the verification ECU 4 receives the response signals from the electronic keys 31 and 32 in response to the request signal, and when the ID code can be verified, turns on the accessory power source and the ignition power source, Instruct and start the engine. On the other hand, when the response signal from the electronic keys 31 and 32 cannot be received, or when the response signal is received but the ID code cannot be verified, the verification ECU 4 determines that the regular electronic keys 31 and 32 are Do not allow power on (engine start) because it is not in the room.

  As will be described later, each of the master key 31 and the spare key 32 is assigned a unique ID, and transmits response signals including different ID codes. The memory 41 stores a first ID code for collating the master key 31 and a second ID code different from the first ID code for collating the spare key 32. When the response signal is received, the verification ECU 4 performs both verification of the ID code included in the response signal and the verification of the first ID code stored in the memory 41 and the verification of the second ID code. Based on the comparison result, it is determined whether the master key 31 or the spare key 32 exists in the communication area of the vehicle interior or exterior transmitter 43. In other words, the verification ECU 4 determines that the master key 31 exists when verification with the first code is possible, and determines that the spare key 32 exists when verification with the second code is possible.

  Further, the verification ECU 4 executes a process for causing the second party other than the driver to feel comfortable when the second party gets into the vehicle. Since the processing is a feature of the present invention, it will be described in detail later.

  The master key 31 and the spare key 32 have the same configuration except for the ID code included in the response signal. The configuration will be described using the spare key 32 as a representative. The spare key 32 includes a control unit 321, a memory 322, and a transmission / reception unit 323. In a memory 322 such as a ROM or a RAM, an ID included in a response signal is stored in addition to a program for processing executed by the control unit 321. As described above, the ID is an ID unique to the spare key 32 that is different from the ID of the master key 31.

  The transmission / reception unit 323 modulates the antenna that transmits / receives wireless data, the modulation data received by the antenna, that is, the demodulation circuit that demodulates the request signal from the vehicle side device, and the data from the control unit 321, that is, the response signal, to the antenna. It consists of a modulation circuit for output.

  When the transmission / reception unit 323 receives a request signal from the vehicle side device (transmitters 42 and 43), the control unit 321 encrypts the ID stored in the memory 322 and includes the encrypted ID code. The transmission / reception unit 323 is caused to transmit a response signal radio wave (a radio wave in an RF band (for example, 300 to 400 MHz band)).

  Next, the configuration of the main air conditioner 7 will be described. FIG. 3 is a block diagram showing the configuration of the main air conditioner 7.

Further, a left rear seat outlet 724 for introducing conditioned air into the area of the left rear seat 104 is provided mainly in the vicinity of the left rear seat 104 (specifically, in front of the left rear seat 104).

  The air conditioning unit 72 includes various configurations for generating desired conditioned air in addition to the air outlets 721 to 724. Specifically, the air conditioning unit 72 includes an inside / outside air damper that switches between an outside air mode in which conditioned air is generated by air taken from the outside and an inside air mode in which air in the vehicle compartment is taken in to generate conditioned air. The air conditioning unit 72 is disposed in a duct through which conditioned air flows, and is a blower fan for adjusting the air volume of the conditioned air, and an evaporator disposed downstream from the blower fan to cool the air and generate cold air. A heater core that is arranged downstream of the evaporator to raise the temperature of the air to generate warm air, an air mix damper that is arranged between the evaporator and the heater core and determines the mixing ratio between the cold air cooled by the evaporator and the warm air heated by the heater core, etc. It has.

  In the present embodiment, the areas of the seats 101 to 104 (see FIG. 2) can be controlled independently of each other. That is, the contents (air temperature, air volume) of the conditioned air introduced from the air outlets 721 to 724 can be made different among the air outlets 721 to 724. Therefore, a blower fan and an air mix damper of the air conditioning unit 72 are provided for each of the air outlets 721 to 724. Moreover, the heater core and the evaporator may be provided for each of the outlets 721 to 724, or may be provided one by one for the front seat and the rear seat.

And a left rear seat operation unit 744 for setting an air conditioning condition in the area of the left rear seat 104. The driver's seat operation unit 741 and the passenger seat operation unit 742 are provided at positions that can be operated by the passengers in the front seats 101 and 102, specifically, for example, at the central instrument panel. The right rear seat operation unit 743 and the left rear seat operation unit 744 are provided at positions that can be operated by the occupants of the rear seats 103 and 104. Specifically, for example, a position between the right rear seat 103 and the left rear seat 104 ( 2) (positions where the air outlets 723 and 724 are provided).

  The air conditioner ECU 71 is configured as well-known computer hardware including a CPU, a ROM, a RAM, an I / O that is a signal input / output circuit, a communication I / F that is a communication interface of an in-vehicle LAN, and the like. The air conditioner ECU 71 controls the operation of the air conditioning unit 72 (for example, opening the air mix damper) while considering the sensor signal input from the air conditioning sensor group 73 so as to satisfy the air conditioning condition input from the operation unit 74. Adjust the degree, and adjust the blower fan speed). At this time, when the air conditioning conditions are individually set from the operation units 741 to 744, for example, when the air conditioning conditions are set from the passenger seat operation unit 742, the air conditioner ECU 71 sets the conditioned air according to the air conditioning conditions. Is introduced from the passenger seat outlet 722 (see FIG. 2).

  Note that the air conditioner ECU 71 determines that the air conditioning condition is not set from the passenger seat operation unit 742, the right rear seat operation unit 743, and the left rear seat operation unit 744, according to the air conditioning conditions set by the driver seat operation unit 741. The entire area is air-conditioned. The air conditioner ECU 71 is connected to the verification ECU 4 so as to be able to communicate with each other by an in-vehicle LAN or a direct connection (direct line).

  Next, the configuration of the seat air conditioner 8 in FIG. 1 will be described. FIG. 4 is a block diagram showing the configuration of the seat air conditioner 8. In the present embodiment, a seat air conditioner 8 is provided for each of the seats 101 to 104. The seat air conditioner 8 includes a Peltier module 82, a blower fan 83, a heater 84, a power switch 85, a temperature setting switch 86, and a seat air conditioning ECU 81 to which they are connected.

  The power switch 85 is a switch for switching on / off of the seat air conditioning, for example, provided on the side surface of the cushion portion of each of the seats 101 to 104. The temperature setting switch 86 is, for example, a switch that is provided on the side surface of the cushion portion of each of the seats 101 to 104 and inputs a set temperature when performing seat air conditioning.

  Ducts through which conditioned air flows are formed inside each of the seats 101 to 104 (inside the seat cushion portion and inside the backrest portion). One end of this duct opens into the passenger compartment, and the other end is connected to an outlet for introducing conditioned air into the area of each of the seats 101-104. This blower outlet is provided in the form which introduces conditioned air from each skin of the cushion part and backrest part of each seat 101-104.

  The Peltier module 82 and the blower fan 83 are provided in the duct. The Peltier module 82 has a well-known Peltier element that is DC-energized in the thickness direction so that one surface is an endothermic surface and the other surface is a heat-dissipating surface. A metal heat block placed in close contact with the surface to be the side, and a metal heat sink placed in close contact with the surface to be the air conditioning heat exchange side. Has a well-known configuration integrated.

  The blower fan 83 is disposed upstream of the Peltier module 82, sucks air into the duct from one end opened in the passenger compartment of the duct, and sends air into the Peltier module 82.

  The heater 84 is provided in each of the cushion part and the backrest part of each seat 101-104, and warms a seat surface at the time of heating. The heater 84 is constituted by a heating wire, for example, and the seat surface is warmed by passing a current through the heating wire.

  The seat air conditioning ECU 81 is configured as well-known computer hardware including a CPU, a ROM, a RAM, an I / O that is a signal input / output circuit, a communication I / F that is a communication interface of an in-vehicle LAN, and the like. The seat air conditioning ECU 81 drives the blower fan 83 when the power switch 85 is turned on, and also sets the set temperature θ set by the temperature setting switch 86, the detected value T of the internal air temperature sensor 731 (see FIG. 3), and the like. A PWM signal corresponding to the above is generated, and the PWM signal is applied to the Peltier module 82. At this time, the seat air-conditioning ECU 81 energizes and drives the Peltier module 82 with different polarities when using cooling and when using heating. Thereby, warm air or cold air having a temperature corresponding to the PWM signal applied to the Peltier module 82 is introduced into the seat area from the air outlet.

  In addition, the seat air conditioning ECU 81 drives the heater 84 during heating to warm the cushion portion and the backrest portion. A switch for driving the heater 84 may be provided separately, and the heater 84 may be driven only when the switch is operated. The seat air conditioning ECU 81 is connected to the verification ECU 4 so as to be able to communicate with each other by an in-vehicle LAN or a direct connection (direct line).

  Further, the seat air conditioning ECU 81 performs seat air conditioning for the second party in advance before the second party other than the driver gets into the vehicle 100. This seat air conditioning will be described later.

  In the vehicle air-conditioning system 1 of FIG. 1 having the above-described configuration, a special pick-up process is performed when a second party other than the driver (such as the driver's family) is picked up by the vehicle 100. Details of this pick-up process will be described below. In the pick-up process, it is assumed that the second person to be picked up carries the spare key 32 (see FIG. 1). FIG. 5 is a flowchart showing a process when the second party is sent to the destination in the pick-up process. The process of the flowchart of FIG. 5 is a process executed by the verification ECU 4 and starts, for example, simultaneously with the engine start of the vehicle 100.

  When the process of FIG. 5 is started, the verification ECU 4 first transmits a request signal from the vehicle interior transmitter 42 to the vehicle interior, and performs vehicle interior verification to determine whether or not the spare key 32 is present in the vehicle interior. (S11). Specifically, when the tuner 44 receives a response signal after transmitting a request signal from the vehicle interior transmitter 42, the ID code included in the response signal and the spare key 32 stored in the memory 41 are used. Collation with the second ID code is performed.

  Next, based on the result of the vehicle interior collation in S11, it is determined whether or not there is a spare key 32 in the vehicle interior (S12). Specifically, when collation with the second ID code is possible, it is determined that there is a spare key 32 in the vehicle interior, while when collation is impossible, it is determined that there is no spare key 32 in the vehicle interior.

  If it is determined that there is no spare key 32 in the passenger compartment (S12: No), the process of the flowchart of FIG. If it is determined that there is a spare key 32 in the passenger compartment (S12: Yes), the seating position of the second party is detected as a scene where the second party is sent to the destination (S13). Specifically, the seating sensors 62 to 64 provided in the seats 102 to 104 other than the driver's seat 101 are operated, and the detection signals of the seating sensors 62 to 64 are acquired. When only the second person who is the person to be picked up is riding other than the driver, one of the detection signals of the seating sensors 62 to 64 is a seating presence signal, and the other two are seating no signals. On the other hand, when a third party other than the second person is also on board, the plurality of seating sensors 62 to 64 detect the seating. Therefore, in S13, all the seat positions where the seating is detected are temporarily stored in the memory 41.

  Next, a request signal is transmitted from the vehicle interior transmitter 42 to the vehicle interior to try to verify the interior of the spare key 32 to determine whether the spare key 32 has been taken out of the vehicle (S14). The process of S14 is a process of determining whether or not the second party has exited the vehicle 100 after arriving at the destination. Further, the process of S14 may be executed constantly while the engine is operating regardless of whether the vehicle 100 is traveling or stopped, or may be executed only when the vehicle 100 is stopped, or the vehicle 100 may be It may be executed when the vehicle stops and the door is opened.

  In S14, when the vehicle interior verification with respect to the spare key 32 is possible (S14: No), the spare key 32 is present in the vehicle interior, and the determination in S14 is performed again, assuming that the second party is being sent. On the other hand, when the vehicle interior verification with respect to the spare key 32 is not possible (S14: Yes), the seating sensors 62 to 64 detect the seating on the assumption that the spare key 32 has been taken out of the vehicle by the arrival at the destination. The seating position changed from “No” to “No” is stored in the memory 41 as the seating position where the second person was seated (S15). Specifically, in S15, the seating sensors 62 to 64 are operated again, and the detection signals (sitting positions) of the seating sensors 62 to 64 are acquired. Then, by comparing the seating position stored in S13 with the seating position acquired in S15, the seating position that has changed from sitting to unsitting is specified.

  Thereby, even if a plurality of people other than the driver are on board, it is possible to carry the spare key 32 and accurately specify the position where the second person (person to be picked up) was sitting. If there are other people who are picked up with the person carrying the spare key 32, that is, when picking up a plurality of people, in S15, the plurality of seating positions are changed from being present to being absent. Become. In this case, a plurality of sitting positions are stored in the memory 41.

  Next, processing in a scene where the second party is sent and then the second party is picked up will be described. FIG. 6 is a flowchart showing processing in a scene where the second party is picked up. In the processing of the flowchart of FIG. 6, S21 to S23 are executed by the verification ECU 4, and S24 is executed by the seat air conditioning ECU 81 (see FIG. 4). The process of the flowchart of FIG. 6 is executed while the vehicle 100 is stopped on the assumption that the sitting position is stored in S15 of FIG. Moreover, the process of the flowchart of FIG. 6 is started at the same time when the vehicle 100 changes from the running state to the stopped state, for example.

  Before S21 in FIG. 6, the verification ECU 4 transmits a request signal from the vehicle interior transmitter 42 (see FIG. 1) to check whether the master key 31 (see FIG. 1) exists in the vehicle interior. Then, it may be confirmed whether or not the driver is in the passenger compartment. Then, when the driver is in the passenger compartment, the process of FIG. 6 is started. When the driver is not in the passenger compartment, the process of FIG. Anyway.

  When the processing of FIG. 6 is started, the verification ECU 4 first transmits a request signal from the vehicle interior transmitter 43 (see FIGS. 1 and 2) to determine whether or not the spare key 32 is present in the peripheral area of the vehicle 100. Car interior verification is performed for this purpose (S21). Next, based on the collation result of S21, it is determined whether or not the second person carrying the spare key 32 is approaching the vehicle 100 (S22). Specifically, when the collation result of S21 is not collated, it is determined that the second person has not approached the vehicle 100, while when collation is possible, it is determined that there is an approach.

  When there is no approach of the second party (S22: No), the process returns to S21, and the vehicle exterior comparison is performed again to continue the determination of whether the second party is approaching. If there is an approach of the second party (S22: Yes), the second party is assumed to be seated at the same position as the seating position for the destination, that is, at the seating position stored in the memory 41 in the previous S15. Assuming that the user is seated, the seat air conditioner 8 (seat air conditioning ECU 81) provided at the seating position is notified of the approach of the second party (S23). When a plurality of seating positions are stored in the previous S15, the approach of the second party is notified to each seat air conditioner 8 provided at these seating positions.

  Receiving the notification, the seat air-conditioning ECU 81 operates the Peltier module 82, the blower fan 83, and the heater 84 (during heating) so as to provide a comfortable cabin space for the second person who is about to get in (S24). That is, the air conditioning mode for the purpose of improving the comfort of the second party is performed. At this time, for example, the seat air conditioning ECU 81 acquires the detection value of the outside air temperature sensor 732 from the main air conditioner 7, and determines whether to perform cooling or heating based on the acquired detection value (vehicle outside temperature). Alternatively, it is determined whether cooling or heating is performed based on the current air conditioning mode setting value in the passenger compartment. Then, the seat air conditioning ECU 81 controls the energization of the Peltier module 82 so that cold air is introduced from the air outlet when it is determined to cool, and when it is determined to be heated, the Peltier module 82 is configured so that warm air is introduced from the air outlet. Energize the module. Further, the seat air conditioning ECU 81 may operate the heater 84 when it is determined to be heating.

  Further, the seat air conditioning ECU 81 determines the energization amount (temperature of the conditioned air) energized to the Peltier module 82 and the rotation speed of the blower fan 83 based on the interior temperature and the exterior temperature detected by the interior temperature sensor 731 and the exterior temperature sensor 732. adjust. Specifically, for example, when the outside temperature of the vehicle indicates a high temperature (summer temperature), the higher the outside temperature, the lower the temperature of the conditioned air and the stronger the air volume, so that the Peltier module 82 and the blower fan 83 are increased. To control. Further, for example, when the outside temperature of the vehicle indicates a low temperature (winter temperature), the Peltier module 82 and the blower fan 83 are controlled so that the temperature of the conditioned air becomes higher and the air volume becomes stronger as the outside temperature becomes lower. .

  The seat air conditioning ECU 81 may control the operations of the Peltier module 82, the blower fan 83, and the heater 84 so that the temperature is set in advance by the temperature setting switch 86.

  As a result, local air conditioning can be automatically performed in advance before the second person gets into the vehicle 100, so that the second party does not need to bother switching the air conditioning mode after getting on, and is comfortable immediately after boarding. I can feel it. In addition, by storing the seating position of the second party when going to the feed, it is sufficient to operate only the minimum required seat air conditioner 8 in the scene of picking up. That is, it is not necessary to operate all the seat air conditioners 8. In addition, when a plurality of persons acting together are picked up, the seat air conditioner 8 on which each person is seated operates in advance before boarding, so that the operation burden on each person can be reduced and each person can get on the board. You can feel comfort immediately. Further, in the above embodiment, since the approach of the second party is detected using the spare key that is originally provided in the electronic key system, the configuration is added or changed in order to detect the approach of the second party. Can be suppressed as much as possible.

  In addition, this invention is not limited to the said embodiment, A various change is possible to the limit which does not deviate from description of a claim. For example, in the above embodiment, the vehicle interior verification of the spare key 32 is performed in FIG. 5 (S11 to S14), but they may be omitted. In other words, the seating position where the seating detection by the seating sensors 62 to 64 has changed from “present” to “no” may be stored as the seating position used in the processing of FIG. As a result, the processing can be simplified.

  In the above embodiment, there is one spare key. However, a plurality of spare keys may be provided, and the processes shown in FIGS. 5 and 6 may be executed for each spare key. Thus, even when a plurality of people are picked up and moved to different places, it is possible to cope.

  In the above embodiment, the seating position at the time of sending is detected and stored in the process of FIG. 5, but the process of FIG. 5 is omitted, and in FIG. 6, the approach of the spare key is detected. All the seat air conditioners may be operated. This also reduces the operational burden associated with switching the air-conditioning mode of the second party who gets into the vehicle, allows the second party to feel comfortable immediately after boarding, and allows the processing in FIG. 5 to be omitted. It can be simplified. In this case, for example, for the seat air conditioner of the seat that the second party did not sit on, the seat air conditioner of the seat air conditioner manually or automatically after confirming the absence of seating with the seating sensor It is sufficient to stop the operation.

  In view of the fact that the second party often sits in the front passenger seat, the processing of FIG. 5 is omitted, and in FIG. 6, when the approach of the spare key is detected, only the front seat air conditioning device is operated. You may make it let it.

  Moreover, in the said embodiment, although seat air-conditioning was performed as an air-conditioning mode for the second party, in addition to or instead of the seat air-conditioning, the main air-conditioning device 7 uses a seat area that is estimated to be seated by the second party. The air conditioning may be performed under optimum air conditioning conditions. That is, for example, when the seating position of the passenger seat is stored in S15 of FIG. 5, the verification ECU 4 notifies the main air conditioner 7 of the seating position of the passenger seat in S23 of FIG. In S24, the main air conditioner 7 introduces conditioned air from the passenger seat outlet 722 (see FIG. 2) into the area of the passenger seat 102, and changes the contents of the conditioned air (air temperature, air volume) to other areas. Different from the contents of the conditioned air introduced from the outlet. For example, when the temperature outside the vehicle is high in the summer, conditioned air having a higher air volume and lower temperature is introduced from the passenger seat outlet 722 compared to other outlets. This also eliminates the need for the second party to bother switching from the air conditioning mode after boarding, and can feel comfort immediately after boarding, as well as impairing the comfort of drivers who are already on board. Can be prevented.

  Further, even if the main air conditioner is a type in which air conditioning control is not possible independently for each seat area, the air conditioning mode for the second party may be performed by the main air conditioner. That is, when the approach of the second party is detected, for example, when the temperature outside the vehicle is high in summer, the conditioned air is changed to a conditioned air having a higher air volume and lower temperature than the currently introduced conditioned air. According to this, although the air conditioning mode is also changed for the area of the driver who has already boarded, for the second party, there is no need to bother switching the air conditioning mode after boarding, You can feel comfortable immediately after boarding. In addition, since it is not necessary to employ a main air conditioner that can control air conditioning independently for each seating area, it is possible to reduce costs and simplify the configuration.

  In the above embodiment, the spare key is identified by having an ID different from that of the master key. However, even if the spare key has the same ID as the master key, the spare key has the following ID. Spare key can be identified. That is, in the scene of picking up a second party, it is confirmed that the electronic key (master key) is present in the passenger compartment by checking the passenger compartment, or the driver's seat is detected. After confirming that the driver is present, the electronic key to be verified in the vehicle exterior verification is determined to be a spare key.

  Moreover, in the said embodiment, although the approach of the 2nd party was detected using the smart entry system, the switch which instruct | indicates locking / unlocking of a door lock to a key is provided, and from the vehicle based on the switch operation The approach of the second party may be detected using a wireless key system that can lock and unlock the door lock from a remote location. Specifically, when a second party carries a spare wireless key, the vehicle-side device receives a radio signal (a signal for instructing unlocking of the door lock) from the spare wireless key. The person is approaching. In this case, instead of the processing of S21 and S22 of FIG. 6, a determination step of “has a signal from the spare wireless key received?” May be executed.

  In the above-described embodiment, the second party carries the spare key to detect the approach of the second party. However, the portable device other than the spare key (the portable device for detecting the approach or the second party possesses it). Mobile phone) may be carried by a second party, and the approach of the second party may be detected based on the presence or absence of communication between the portable device and the vehicle-side device. In this case, each of the portable device and the vehicle-side device has a function capable of communicating with each other in the vehicle peripheral area.
