It is possible to switch the conditioned air by blowing the conditioned air from the instrument panel outlet 33 when necessary.

  FIG. 3 shows a flowchart during pre-air-conditioning by the control unit 20 of the vehicle air-conditioning apparatus. The control part 20 of this vehicle air conditioner will start the process shown in FIG.

  First, it is determined whether a pre-air conditioning request has been received from the remote transmitter 1 (S100). Specifically, it is determined whether or not the signal received by the transmission / reception unit 10 is a signal instructing a start request for pre-air conditioning from the remote transmitter 1.

  Here, when the signal received by the transmission / reception unit 10 is not a signal for instructing a start request for pre-air-conditioning, the determination in S100 is NO and the process is terminated.

  Moreover, when the signal received by the transmission / reception part 10 is a signal which instruct | indicates the start request | requirement of pre air conditioning, determination of S100 becomes YES and next acquires a sensor output (S102). Specifically, a signal output from the inside air temperature sensor 11, a signal output from the outside air temperature sensor 12, and a signal output from the solar radiation sensor 13 are acquired.

  Next, air conditioning control determination is performed (S104). That is, it is determined whether to control cooling or heating the passenger compartment. In this embodiment, the vehicle interior set temperature is specified from the set temperature set by the user's air conditioner switch operation or remote operation, the vehicle interior air temperature is identified based on the signal output from the interior air temperature sensor 11, and the vehicle When the inside air temperature of the vehicle is higher than the threshold, the cooling control is performed. When the inside air temperature of the vehicle is lower than the threshold, the heating control is performed. The cooling and heating thresholds are determined based on the cabin interior set temperature. When the vehicle interior set temperature is high, the cooling determination threshold is increased, and when the vehicle interior set temperature is low, the heating determination threshold is set low.

  Here, when the inside air temperature of the vehicle is high and the determination result of S104 is cooling control, it is next determined whether or not the amount of solar radiation irradiated to the vehicle is equal to or greater than a predetermined reference value (A). (S106). The amount of solar radiation irradiated on the vehicle can be specified based on a signal output from the solar radiation sensor 13.

  Here, when the amount of solar radiation irradiated to the vehicle is less than a predetermined reference value (A), such as when the vehicle is in an underground parking lot or in the shade, the determination in S106 is NO, and the entire vehicle interior is Air conditioning control is performed (S108). Specifically, the electric fin 31a provided in the face air outlet 31 of the vehicle is operated so that the air blown out from the face air outlet 31 is directed to the entire vehicle interior, and the seat is seated from the seat seat surface or the seat back. Air-conditioning air is prevented from being blown out from the seat outlet 32 that blows out air toward the occupant and the instrument panel outlet 33 that blows out air toward the surface of the instrument panel 43. In addition, by preventing the conditioned air from being blown out from the seat blowout port 32 and the instrument panel blowout port 33 in this way, it becomes possible to blow out stronger conditioned airflow from the face blowout port 31.

  Thus, even when the determination result of S104 is cooling control, if the amount of solar radiation irradiated to the vehicle is small, the entire vehicle interior is cooled to control the entire vehicle interior, so that comfort is improved. It is trying to improve.

  If the amount of solar radiation irradiated to the vehicle is equal to or greater than a predetermined reference value (A), the determination in S106 is YES, and switching is performed so that the specific interior goods 40 are concentratedly controlled for cooling (S110). ). Specifically, the electric fin 31a provided in the face air outlet 31 of the vehicle is operated so that the cool air blown from the face air outlet 31 is directed to the vehicle handle 41, and the seat is seated from the seat seat surface or the seat back. The mode is switched to a mode in which cool air is blown out from the seat outlet 32 that blows out air toward the occupant and the instrument panel outlet 33 that blows out air toward the surface of the instrument panel 43.

  Thus, in this embodiment, when it is determined that the vehicle interior is controlled to be cooled and the amount of solar radiation irradiated to the vehicle is determined to be equal to or greater than a predetermined reference value, the vehicle handle 41 that is likely to have heat is used. The air conditioner is determined to be in a specific situation where the air conditioning control should be performed with priority given to the interior parts 40 of the seat 42 and the instrument panel 43, and the air conditioning air is switched so as to control the cooling of the interior parts 40 in a concentrated manner. We are trying to improve.

  If the inside air temperature of the vehicle is equal to or lower than the threshold value and the determination result in S104 is heating control, it is next determined whether or not the amount of solar radiation irradiated to the vehicle is equal to or greater than a predetermined reference value (B). Determine (S114). The amount of solar radiation irradiated on the vehicle can be specified based on a signal output from the solar radiation sensor 13.

  Here, when the amount of solar radiation with which the vehicle is irradiated is equal to or greater than a predetermined reference value (B), the determination in S114 is YES, and the entire vehicle interior is air-conditioned (S108). Specifically, the electric fin 31a provided in the face air outlet 31 of the vehicle is operated so that the air blown out from the face air outlet 31 is directed to the entire vehicle interior, and the seat is seated from the seat seat surface or the seat back. Air-conditioning air is prevented from being blown out from the seat outlet 32 that blows out air toward the occupant and the instrument panel outlet 33 that blows out air toward the surface of the instrument panel 43. In addition, by preventing the conditioned air from being blown out from the seat blowout port 32 and the instrument panel blowout port 33 in this way, it becomes possible to blow out stronger conditioned airflow from the face blowout port 31.

  As described above, even when the determination result of S104 is heating control, when the amount of solar radiation irradiated to the vehicle is large, the entire vehicle interior is heated to control the entire vehicle interior in order to warm the vehicle. I try to improve.

  Moreover, when the amount of solar radiation with which the vehicle is irradiated is less than a predetermined reference value (B), the determination in S114 is NO, and switching is performed so that the specific interior goods 40 are centrally controlled for heating (S110). ). Specifically, the electric fin 31a provided in the face outlet 31 of the vehicle is operated so that the warm air blown out from the face outlet 31 is directed to the handle 41 of the vehicle, and from the seat seat surface or the seat back. The mode is switched to a mode in which warm air is blown from the seat blowout port 32 that blows out air toward the seated passenger and the instrument panel blowout port 33 that blows out air toward the surface of the instrument panel 43.

  Thus, in this embodiment, when it is determined that the vehicle interior is controlled to be heated and the amount of solar radiation applied to the vehicle is less than a predetermined reference value, the vehicle handle 41, seat 42, and The interior panel 40 of the instrument panel 43 is determined to be in a specific situation in which air conditioning control is to be given priority, and the conditioned air is switched so as to control the heating of the interior products 40 in a concentrated manner to improve comfort. I am doing so.

  In S112, it is determined whether or not pre-air conditioning has been completed in accordance with a user operation. Here, when the end of the pre-air conditioning is not instructed by the user operation, the determination in S112 is NO, the process returns to S102, and the above process is repeatedly performed. If the end of pre-air conditioning is instructed by a user operation, the determination in S112 is YES and the process ends.

  According to the above-described configuration, when there is a pre-air-conditioning start request from the remote transmitter 1, the vehicle surroundings should be controlled with priority given to at least one interior component of the vehicle handle, seat, and instrument panel. When it is determined whether or not the vehicle is in a specific situation, and it is determined that the surrounding environment of the vehicle is a specific situation where air conditioning control should be given priority to the interior parts, the air conditioning Since it is switched, it is possible to improve comfort during pre-air conditioning.
