  FIG. 3 is a flowchart showing a temperature control processing procedure when boarding. The control unit 11 performs the following regular processing until the prime mover of the vehicle C is not started and the vehicle C door is locked, or until a fixed time elapses after the user gets on the vehicle. First, the control unit 11 receives the signal transmitted from the portable communication device A at the reception unit 16 (step S11). Next, the control unit 11 determines whether or not the signal is a boarding notice signal (step S12). When it determines with it being a boarding announcement signal (step S12: YES), the control part 11 starts the air conditioner 2 by transmitting a control signal to air conditioner ECU21 (step S13). Subsequently, the control part 11 controls the target temperature which concerns on operation | movement of the air conditioner 2 (step S14).

  FIG. 4 is a flowchart showing a processing procedure related to control of the target temperature in the vehicle. The control unit 11 detects the temperature outside the vehicle with the vehicle outside thermometer 5 (step S31). And the control part 11 acquires the preset temperature of the air conditioner 2, ie, the temperature which the user set to the air conditioner 2, from air conditioner ECU21 (step S32). Next, the control unit 11 determines whether or not the temperature difference between the set temperature in the vehicle set by the user and the temperature outside the vehicle detected in step S31 is equal to or less than a predetermined temperature (step S33). The storage unit 13 stores a predetermined temperature. Hereinafter, the temperature difference between the vehicle interior temperature set by the user and the vehicle exterior temperature detected by the vehicle exterior thermometer 5 is appropriately referred to as an interior / external temperature difference. When it determines with it being below predetermined temperature (step S33: YES), the control part 11 determines a user's preset temperature as target temperature (step S34), and complete | finishes a process.

  When it is determined that the internal / external temperature difference is not less than or equal to the predetermined temperature (step S33: NO), the control unit 11 determines whether or not the temperature outside the vehicle detected in step S31 is higher than the set temperature of the user. (Step S35). When it is determined that the temperature outside the vehicle is higher than the set temperature of the user (step S35: YES), the control unit 11 determines the temperature obtained by subtracting the predetermined temperature from the temperature outside the vehicle as the target temperature ( Step S36), the process is finished. When it is determined that the temperature outside the vehicle is lower than the temperature set by the user (step S35: NO), the control unit 11 determines the temperature obtained by adding the predetermined temperature to the temperature outside the vehicle as the target temperature. (Step S37), the process ends. The control unit 11 controls the operation of the air conditioner 2 by transmitting information such as the target temperature determined in the process of step S36 or step S37 and the temperature detected by the in-vehicle thermometer 4 to the air conditioner ECU 21. Then, control is performed so that the temperature inside the vehicle matches the target temperature.

  Returning to FIG. 3, the processing after step S14 will be described. When the process of step S14 is completed or when it is determined in step S12 that the boarding advance notice signal has not been received (step S12: NO), the control unit 11 determines whether the user has boarded (step S12). S15). The determination in step S15 does not determine whether or not the vehicle is in a steady state, but determines whether or not there is a change from the state in which the user is not in the boarding state. For example, the control unit 11 may be configured to detect the open / close state of the vehicle door by monitoring the on / off state of the door switch 6 and to determine that the user has boarded when the vehicle door is opened / closed. In addition, a seating sensor may be provided on the vehicle seat, and a user's boarding may be detected based on a signal input from the seating sensor to the input unit 14. The seating sensor is, for example, a sensor having a piezoelectric element that generates electricity by the pressure of a user seated on a seat. Furthermore, it may be configured to detect the user's boarding by using an attachment / detachment sensor that detects attachment / detachment of the seat belt. When a tongue is inserted into the buckle of the seat belt, it is possible to detect the user's boarding based on a signal input to the input unit 14 from the attachment / detachment sensor. Furthermore, when the smart entry system is mounted on the vehicle C, the user's boarding may be detected by determining whether or not the portable device constituting the smart entry system is in the vehicle.

  When it determines with the user having boarded (step S15: YES), the control part 11 starts time measurement by the time measuring part 17 (step S16). By the process of step S16, the time measuring unit 17 measures the elapsed time after the user gets on.

  And the control part 11 determines whether the air conditioner 2 is operating by inquiring to air conditioner ECU21 (step S17). If it is determined that the air conditioner 2 is not operating (step S17: NO), the control unit 11 starts the air conditioner 2 (step S18) and controls the target temperature related to the operation of the air conditioner 2 ( Step S19). The processing content of step S18 and step S19 is the same as that of step S13 and step S14.

  When the process of step S19 is completed, when the user's boarding is not detected in step S15 (step S15: NO), the control unit 11 determines that the air conditioner 2 is operating in step S17 (step S15). (S17: YES), the time measuring unit 17 is referred to and it is determined whether or not the first predetermined time has elapsed since the boarding (step S20). The storage unit 13 stores the first predetermined time.

  When it determines with the 1st predetermined time not having passed since boarding (step S20: NO), the control part 11 complete | finishes a process. When it determines with the 1st predetermined time having passed since the time of boarding (step S20: YES), the control part 11 determines a user's preset temperature as target temperature (step S21), and complete | finishes a process. The control unit 11 transmits information such as the target temperature determined in the process of step S21 and the temperature detected by the in-vehicle thermometer 4 to the air conditioner ECU 21 to control the operation of the air conditioner 2, thereby Control is performed so that the temperature matches the target temperature.

  FIG. 5 is a flowchart showing a temperature control processing procedure when the user gets off the vehicle. When the navigation device 3 is executing control for guiding the vehicle to the destination, the control unit 11 periodically executes the following processing. The control unit 11 inquires and obtains the time required for arrival at the destination from the navigation device 3 (step S51). Then, the control unit 11 determines whether or not the time required for arrival at the destination is less than the second predetermined time (step S52). The storage unit 13 stores the second predetermined time. When it determines with the said required time not being less than 2nd predetermined time (step S52: NO), the control part 11 finishes a process. When it determines with required time being less than 2nd predetermined time (step S52: YES), the control part 11 controls the target temperature which concerns on operation | movement of the air conditioner 2 (step S53), and complete | finishes a process. The process of step S53 is the same as the process of step S14. By the process of step S53, the operation of the air conditioner 2 is controlled so that the temperature difference between the outside of the vehicle and the inside of the vehicle is equal to or lower than a predetermined temperature.

  FIG. 6 is a timing chart showing how the temperature inside the vehicle is controlled when the temperature outside the vehicle is high. The horizontal axis represents time, and the vertical axis represents the temperature inside and outside the vehicle. For example, the case where the user notifies the temperature control device 1 of a boarding notice signal using the portable communication device A will be described. The set temperature inside the vehicle set by the user in the air conditioner 2 is lower than the temperature outside the vehicle by a predetermined temperature or more. In this case, the temperature control device 1 sets the target temperature in the vehicle so that the temperature difference between the temperature outside the vehicle and the temperature inside the vehicle is equal to or less than a predetermined temperature regardless of the user's set temperature, and the air conditioner 2 is started. For example, the temperature control device 1 determines a temperature that is a predetermined temperature lower than the temperature outside the vehicle as the target temperature, and transmits the determined target temperature to the air conditioner 2.

  As described above, even when the set temperature of the user is considerably lower than the temperature outside the vehicle, the temperature difference between the temperature inside the vehicle and the temperature outside the vehicle is controlled to be equal to or lower than a predetermined temperature. Therefore, when the user gets on, it is possible to prevent the user from losing physical condition due to a sudden temperature change inside and outside the vehicle.

  Next, when the temperature control device 1 detects the user's boarding, the temperature inside the vehicle, the temperature outside the vehicle, and the temperature outside the vehicle are set for the first predetermined time after the user gets on, regardless of the set temperature of the user. The temperature inside the vehicle is controlled so that the temperature difference between the two becomes a predetermined temperature or less. The first predetermined time is a time required for the user to get used to the temperature inside the vehicle.

  The temperature control device 1 controls the operation of the air conditioner 2 according to the set temperature of the user when the first predetermined time has elapsed since the user got on. Therefore, after the first predetermined time has elapsed since the user got on the vehicle, that is, after the user has become accustomed to the temperature inside the vehicle, the temperature inside the vehicle is controlled to become the set temperature of the user. .

  Further, when the destination is set in the navigation device 3, the temperature control device 1 acquires the time information required for the vehicle C to arrive at the destination from the navigation device 3. Then, at the stage when the vehicle C arrives at the second predetermined time before the arrival at the destination, the temperature control device 1 sets the target temperature so that the temperature difference between the temperature inside the vehicle and the temperature outside the vehicle becomes a predetermined temperature or less. Set and control the operation of the air conditioner 2.

  Therefore, even when the user gets off the vehicle, the temperature difference between the temperature inside the vehicle and the temperature outside the vehicle is below a predetermined temperature, and the user is prevented from losing physical condition due to a sudden temperature change inside and outside the vehicle. Can do.

  FIG. 7 is a timing chart showing how the temperature inside the vehicle is controlled when the temperature outside the vehicle is low. As in FIG. 6, the horizontal axis represents time, and the vertical axis represents temperatures inside and outside the vehicle. The set temperature in the vehicle set by the user in the air conditioner 2 is higher than the temperature outside the vehicle by a predetermined temperature or more. In this case, the temperature control device 1 sets the target temperature in the vehicle so that the temperature difference between the temperature outside the vehicle and the temperature inside the vehicle is equal to or less than a predetermined temperature regardless of the user's set temperature, and the air conditioner 2 is started. For example, the temperature control device 1 determines a temperature that is higher than the temperature outside the vehicle by a predetermined temperature as the target temperature, and transmits the determined target temperature to the air conditioner 2.

  In this way, even when the set temperature of the user is considerably higher than the temperature outside the vehicle, the temperature difference between the temperature inside the vehicle and the temperature outside the vehicle is controlled to be equal to or lower than a predetermined temperature. Therefore, when the user gets on, it is possible to prevent the user from losing physical condition due to a sudden temperature change inside and outside the vehicle.

  Next, when the temperature control device 1 detects the user's boarding, the temperature inside the vehicle, the temperature outside the vehicle, and the temperature outside the vehicle are set for the first predetermined time after the user gets on, regardless of the set temperature of the user. The temperature inside the vehicle is controlled so that the temperature difference between the two becomes a predetermined temperature or less.

  The temperature control device 1 controls the operation of the air conditioner 2 according to the set temperature of the user when the first predetermined time has elapsed since the user got on.

  Further, when the destination is set in the navigation device 3, the temperature control device 1 determines whether the temperature inside the vehicle and the temperature outside the vehicle at the stage when the vehicle C arrives at the destination before the second predetermined time. A target temperature is set so that the temperature difference is equal to or lower than a predetermined temperature, and the operation of the air conditioner 2 is controlled.

  Therefore, even when the user gets off the vehicle, the temperature difference between the temperature inside the vehicle and the temperature outside the vehicle is below a predetermined temperature, and the user is prevented from losing physical condition due to a sudden temperature change inside and outside the vehicle. Can do.

  According to the temperature control system and the temperature control device 1 configured as described above, the target temperature in the vehicle can be determined so that the temperature difference between the inside and outside of the vehicle when getting on or off the vehicle is equal to or lower than a predetermined temperature. It is possible to prevent the user from losing physical condition due to a sudden temperature change inside and outside the vehicle at the time of getting off or getting off.

  The timer 17 measures the elapsed time after detecting the user's boarding, and the control unit 11 detects the temperature inside the vehicle and the outside of the vehicle until the first predetermined time elapses after getting on. The target temperature in the vehicle is determined such that the temperature difference from the temperature of the vehicle is equal to or less than a predetermined temperature. Therefore, the temperature inside the vehicle does not drop abruptly compared to the temperature inside the vehicle, and the user can be prevented from losing physical condition.

  Furthermore, the control part 11 determines the target temperature in a vehicle based on the preset temperature set to the air conditioner 2 by the user, when 1st predetermined time passes after boarding. Therefore, it is possible to control the temperature inside the vehicle so as to achieve a set temperature desired by the user while avoiding a rapid temperature change in the temperature inside and outside the vehicle.

  Furthermore, when the boarding notice signal is received, the control unit 11 starts the air conditioner 2 and determines the target temperature in the vehicle so that the temperature difference between the temperature inside the vehicle and the temperature outside the vehicle becomes a predetermined temperature or less. To do.
