  In this automobile of the present invention, the margin temperature is set so as to increase as the difference between the outside air temperature and the set temperature in the passenger compartment increases, and the air conditioner is turned on with the external power supply means connected to the external power source. When the passenger compartment is heated, the compressor stops driving when the passenger compartment temperature is lower than the heating high-side control temperature, which is the set temperature plus the margin temperature, and then exceeds the heating high-side control temperature. The air conditioning drive means and the external power supply means are controlled so that the secondary battery is charged, and the temperature of the passenger compartment is reduced from the set temperature to the lower control temperature during heating, which is lower than the set temperature by the margin temperature. The air conditioning drive means and the external power supply means are controlled so that the compressor is driven when the temperature falls below the side control temperature, and the air conditioner is turned on while the external power supply means is connected to the external power source, and the occupant When the temperature of the passenger compartment decreases from the set temperature by the margin temperature to a temperature lower than the low control temperature during cooling and below the low control temperature during cooling, the compressor is stopped and The air conditioning drive means and the external power supply means are controlled so that the secondary battery is charged, and the temperature of the passenger compartment is lower than the cooling high side control temperature obtained by adding the margin temperature to the set temperature to the cooling high side control temperature. The air-conditioning drive means and the external power supply means are controlled to drive the compressor when the above is reached. Here, the margin temperature is set so as to increase as the difference between the outside air temperature and the passenger compartment set temperature increases, because the compressor drive duty increases as the temperature difference up to the set temperature increases. This is to reduce the rate of time for driving the compressor. Therefore, the compressor is adjusted for air conditioning using the high and low control temperatures obtained from the margin and set temperatures that tend to increase as the difference between the outside air temperature and the passenger compartment setting temperature increases.

The required air conditioning ratio setting means for setting the required air conditioning ratio, and the required charging completion time setting for setting the required charging completion time by adding the time corresponding to the set required air conditioning ratio to the set required charging time Means and a notifying means for notifying the set required time for completion of charging. If it carries out like this, a passenger | crew can be notified of the charge completion required time which completes charge of a secondary battery with air conditioning.

  Furthermore, the automobile of the present invention further comprises a battery connection release means for connecting and releasing the connection between the secondary battery and the battery power system, and the charge-time charging air-conditioning control means is configured to operate when the compressor is driven. It may be a means for controlling the battery connection release means so that the connection between the secondary battery and the battery power system is released. If it carries out like this, electric power at the time of driving the compressor with which an air-conditioner is provided can be ensured enough. In this case, when the secondary battery reaches a predetermined power storage state, the charge-time air conditioning control means at the time of charging, the secondary battery and the battery regardless of the temperature difference between the passenger compartment temperature and the set temperature. It may be a means for controlling the battery connection release means so that the connection with the power system is released. In this way, it is possible to avoid making the secondary battery into a storage state exceeding a predetermined storage state.

  Further, in the automobile of the present invention, the charging-time charging air-conditioning control means is configured such that, even if a condition for driving the compressor is satisfied, when the time for continuously charging the secondary battery is less than a predetermined time, the secondary battery Means for controlling the air-conditioning drive means and the external power supply means so that the secondary battery is charged without driving the compressor until the time for continuously charging the battery reaches the predetermined time or longer. There can be. If it carries out like this, a secondary battery can be charged over a predetermined time at least continuously, and it can control that the charge of a secondary battery and the drive of a compressor are switched frequently.

  In this automobile control method of the present invention, the margin temperature is set so as to increase as the difference between the outside air temperature and the passenger cabin set temperature increases, and the air conditioner is connected with the external power supply means connected to the external power source. When the passenger compartment is turned on and the passenger compartment temperature is lower than the heating high side control temperature, which is equal to the set temperature plus the margin temperature, the compressor is driven when it reaches the heating high side control temperature or higher. The air conditioning drive means and the external power supply means are controlled so that the secondary battery is charged and the temperature of the passenger compartment is reduced from the set temperature by the margin temperature from the state above the low control temperature during heating. The air conditioning drive means and the external power supply means are controlled so that the compressor is driven when the temperature becomes lower than the lower control temperature during heating, and the air conditioner is turned on with the external power supply means connected to the external power supply. When the passenger compartment is being cooled, the compressor is driven when the passenger compartment temperature is lower than the lower control temperature during cooling from the condition higher than the lower control temperature during cooling, which is the margin temperature reduced from the set temperature. Controls the air-conditioning drive means and external power supply means to stop and charge the secondary battery, and at the time of cooling from the state where the temperature of the passenger compartment is lower than the high-side control temperature at the time of cooling when the margin temperature is added to the set temperature. The air-conditioning driving means and the external power supply means are controlled to drive the compressor when the temperature reaches the high side control temperature or higher. Here, the margin temperature is set so as to increase as the difference between the outside air temperature and the passenger compartment set temperature increases, because the compressor drive duty increases as the temperature difference up to the set temperature increases. This is to reduce the rate of time for driving the compressor. Therefore, the compressor is adjusted for air conditioning using the high and low control temperatures obtained from the margin and set temperatures that tend to increase as the difference between the outside air temperature and the passenger compartment setting temperature increases. By driving or stopping, charging of the secondary battery and air conditioning of the passenger compartment can be performed more appropriately.

  Next, the form for implementing this invention is demonstrated using an Example.

  FIG. 1 is a configuration diagram showing an outline of the configuration of a hybrid vehicle 20 as an embodiment of the present invention. The hybrid vehicle 20 according to the embodiment includes an engine 22 that uses gasoline, light oil, or the like as fuel, and a drive shaft that has a carrier connected to the crankshaft 26 of the engine 22 and is connected to drive wheels 39a and 39b via a differential gear 38.

Comprising the use electronic control unit 70.

  The battery 50 is configured as a lithium ion secondary battery, and a power line 54 is connected to the inverters 41 and 42 via a system main relay 56. The power line 54 is connected to a DC / DC converter 90 that converts the voltage of the DC power and supplies it to the battery 50. The DC / DC converter 90 is connected to a commercial power source outside the vehicle (for example, for home use). An AC / DC converter 92 that converts AC power supplied from a power source (AC 100 V, etc.) via a power plug 94 to DC power is connected. Therefore, by connecting the power plug 94 to the commercial power source and controlling the AC / DC converter 92 and the DC / DC converter 90, the battery 50 can be charged with the power from the commercial power source.

  The air conditioner 60 includes a compressor 64 driven by an inverter 65 connected to an electric power line 54 to which the battery 50 is connected, a refrigeration cycle 62 including a condenser, an expansion valve, and an evaporator (not shown), and an evaporator of the refrigeration cycle 62. A blower 66 that blows air cooled by heat exchange or heated air to the outlet 21 a of the passenger compartment 21 and an operation panel 67 attached to the passenger compartment 21 are provided. The air conditioner 60 is controlled by an air conditioning electronic control unit (hereinafter referred to as an air conditioning ECU) 68. The air conditioning ECU 68 is set to an ON / OFF signal from a blower switch 67a that is attached to the operation panel 67 and operates to turn on and off the air conditioning, and a setting from a set temperature switch 67b that is also attached to the operation panel 67 and sets the temperature in the passenger compartment 21. A temperature Tin *, an occupant room temperature Tin from a temperature sensor 67c that is attached to the operation panel 67 and detects the temperature in the occupant room 21 are input, and an air conditioner ECU 68 receives an inverter 65 for driving the compressor 64, A drive signal or the like to the blower 66 is output. The air conditioning ECU 68 drives and controls the air conditioner 60 (such as the compressor 64 and the blower 66) based on the input signal so that the passenger room temperature Tin becomes the set temperature Tin *. The air conditioning ECU 68 is in communication with the hybrid electronic control unit 70, and transmits data related to the state of the air conditioner 60 to the hybrid electronic control unit 70 as needed, or control from the hybrid electronic control unit 70. Receive signals.

  The hybrid electronic control unit 70 is configured as a microprocessor centered on the CPU 72, and in addition to the CPU 72, a ROM 74 for storing processing programs, a RAM 76 for temporarily storing data, an input / output port and communication not shown. And a port. The hybrid electronic control unit 70 drives signals from various sensors that detect the operating state of the engine 22 (for example, a crank position of the crankshaft 26 of the engine 22 from a crank position sensor not shown), and drives the motors MG1 and MG2. Signals necessary for control (for example, the rotational position of the rotors of the motors MG1, MG2 from a rotational position detection sensor (not shown), the phase current applied to the motors MG1, MG2 from a current sensor (not shown)), the battery 50 (For example, voltage between terminals of the battery 50 from a voltage sensor (not shown), charge / discharge current of the battery 50 from a current sensor (not shown), battery temperature Tb from the temperature sensor 51, etc.), ignition switch Ignition signal and shift lever operation Shift position SP from the shift position sensor that detects the position, accelerator opening Acc from the accelerator pedal position sensor that detects the amount of depression of the accelerator pedal, brake pedal position BP from the brake pedal position sensor that detects the amount of depression of the brake pedal The vehicle speed V from the vehicle speed sensor, the outside air temperature Tout from the outside air temperature sensor 82 that detects the outside air temperature, and the like are input via an input port (not shown). Further, from the hybrid electronic control unit 70, a control signal for controlling the operation of the engine 22, a control signal for the inverters 41 and 42, a drive signal for the system main relay 56, and a display 80 provided in the vicinity of the driver's seat. A display signal, a control signal to the AC / DC converter 92, a control signal to the DC / DC converter 90, and the like are output via an output port (not shown). The hybrid electronic control unit 70 communicates with the air conditioning ECU 68 via a communication port (not shown). The hybrid electronic control unit 70 calculates the rotational speed of the crankshaft 26, that is, the rotational speed Ne of the engine 22 based on the crank position from the crank position sensor, and rotates the motors MG1 and MG2 from the rotational position detection sensor. The rotational speeds Nm1 and Nm2 of the motors MG1 and MG2 are calculated based on the rotational position of the child, and the charged amount SOC is calculated based on the integrated value of the charge / discharge current of the battery 50.

  The hybrid vehicle 20 of the embodiment configured as described above calculates a required torque to be output to the drive shaft 32 based on the accelerator opening Acc and the vehicle speed V corresponding to the depression amount of the accelerator pedal by the driver, and this required torque. The engine 22, the motor MG 1, and the motor MG 2 are controlled to be operated so that the required power corresponding to is output to the drive shaft 32. As operation control of the engine 22, the motor MG1, and the motor MG2, the operation of the engine 22 is controlled so that power corresponding to the required power is output from the engine 22, and all of the power output from the engine 22 is transmitted to the planetary gear mechanism 30. Torque conversion is performed by the motor MG1 and the motor MG2 and output to the drive shaft 32. The torque conversion operation mode for driving and controlling the motor MG1 and the motor MG2 and the required power and the power required for charging and discharging the battery 50 are met. Operation of the engine 22 is controlled so that power is output from the engine 22, and all or part of the power output from the engine 22 with charge / discharge of the battery 50 is transmitted to the planetary gear mechanism 30, the motor MG1, and the motor MG2. So that the required power is output to the drive shaft 32 with torque conversion by the motor. Charge-discharge drive mode for driving and controlling the G1 and the motor MG2, there is a motor operation mode in which operation control so as to stop operation of the engine 22 to output power to meet the required power from the motor MG2 to the drive shaft 32. Both the torque conversion operation mode and the charge / discharge operation mode are modes in which the engine 22 and the motors MG1, MG2 are controlled so that the required power is output to the drive shaft 32 with the operation of the engine 22. Since there is no difference in the control, both are hereinafter referred to as the engine operation mode.

  In addition, in the hybrid vehicle 20 of the embodiment, the vehicle 50 is running so that the stored amount SOC of the battery 50 is low enough to start the engine 22 sufficiently when reaching the home or a preset charging point. The charging / discharging control of the battery 50 is performed, and after stopping the vehicle at home or at a preset charging point, the power plug 94 is connected to a commercial power source to control the DC / DC converter 90 and the AC / DC converter 92. Thus, the battery 50 is fully charged or in a predetermined charging state lower than the full charging (for example, a state where the storage amount SOC is 80% or 85%) by the electric power from the commercial power source. When the system is started after the battery 50 is charged, the threshold value Shv (for example, the charge amount SOC of the battery 50 is set so that the engine 22 can be started except when the power required for the vehicle is large). The motor travels in the motor operation mode until 25% or 30%.

  Next, the operation of the hybrid vehicle 20 of the embodiment thus configured, particularly the operation when the battery 50 is charged using the commercial power supply while the passenger compartment 21 is air-conditioned by the air conditioner 60 will be described. FIG. 2 is a flowchart showing an example of a heating charge control routine executed by the hybrid electronic control unit 70, and FIG. 3 is a flowchart showing an example of a cooling charge control routine executed by the hybrid electronic control unit 70. is there. These routines are executed when the power plug 94 is connected to a commercial power supply and the air conditioner 60 is turned on with the hybrid vehicle 20 stopped.

  When the heating control routine is executed, the CPU 72 of the hybrid electronic control unit 70 first performs heating such as the outside air temperature Tout from the outside air temperature sensor 82, the set temperature Tin * in the air conditioner 60, and the storage amount SOC of the battery 50. A process of inputting data necessary for control when charging the battery 50 is performed (step S100). Here, the set temperature Tin * in the air conditioner 60 is input by the occupant from the air conditioning ECU 68 by communication through the set temperature switch 67b of the operation panel 67. The storage amount SOC of the battery 50 is input by reading the value stored in a predetermined area of the RAM 76, which is calculated based on the integrated value of the charge / discharge current of the battery 50.

  When the data is input in this manner, a difference between the value Sref set in advance as the storage amount SOC when the charging of the battery 50 is completed (for example, 80% or 85% as the storage amount SOC) and the input storage amount SOC of the battery 50. Based on the charged amount difference ΔSOC (ΔSOC = Sref−SOC), a required charging time Tchg as a time required for charging the battery 50 is set (step S110). In the embodiment, the required charging time Tchg is obtained by previously obtaining the relationship between the charged amount difference ΔSOC and the required charging time Tchg through experiments and stored in the ROM 74 as a required charging time setting map, and the charged amount difference ΔSOC is given. And the corresponding required charging time Tchg is derived from the map. An example of the required charging time setting map is shown in FIG. The required charging time setting map of the embodiment is set so that the required charging time Tchg increases as the charged amount difference ΔSOC increases, as shown in the figure. This is based on the fact that it takes a longer time as the amount of power to be stored in the battery 50 is larger before the charging of the battery 50 is completed.

  Next, the battery 50 is charged while heating based on the temperature difference ΔT (ΔT = | Tin * −Tout |) which is the difference between the set temperature Tin * and the outside air temperature Tout in the air conditioner 60 and the required charging time Tchg. A margin temperature α for setting a permissible range from the set temperature Tin * of the passenger compartment 21 at the time is set (step S120). In the embodiment, for the margin temperature α, the relationship between the temperature difference ΔT, the required charging time Tchg, and the margin temperature α is obtained in advance by experiments and stored in the ROM 74 as a margin temperature setting map. When the time Tchg is given, it is set by deriving the corresponding margin temperature α from the map. An example of the margin temperature setting map is shown in FIG. As shown in the figure, the margin temperature setting map of the embodiment is set so that the margin temperature α increases as the temperature difference ΔT increases, and the margin temperature α increases as the required charging time Tchg increases. As will be described later, when the temperature Tin of the passenger compartment 21 becomes lower than the low-side control temperature Tlow (Tin * -α) obtained by subtracting the margin temperature α from the set temperature Tin *, the margin temperature α is set. When the passenger compartment 21 is heated by driving the compressor 64 and the temperature Tin of the passenger compartment 21 becomes higher than the high-side control temperature Thi (Tin * + α) obtained by adding the margin temperature α to the set temperature Tin *. In addition, it is used for control to stop the driving of the compressor 64 of the air conditioner 60. Therefore, when the margin temperature α is small, the passenger compartment 21 is accurately maintained at the set temperature Tin *, but the compressor 64 of the air conditioner 60 is frequently driven and stopped, and when the margin temperature α is large. The passenger compartment 21 is maintained at the set temperature Tin * with low accuracy, but the frequency of driving and stopping the compressor 64 of the air conditioner 60 is reduced. Further, when the compressor 64 is frequently driven and stopped, the load between the compressor 64 and the compressor 64 is relatively small because the difference between the temperature Tin of the passenger compartment 21 and the set temperature Tin * is small. However, if the frequency of driving and stopping of the compressor 64 is lowered, the difference between the temperature Tin of the passenger compartment 21 and the set temperature Tin * increases, so that the load when the compressor 64 is driven becomes relatively large. Therefore, in the embodiment, the larger the temperature difference ΔT, the larger the margin temperature α is because the longer the temperature difference ΔT is, the shorter the driving time of the compressor 64 is and the charging time of the battery 50 is secured. The margin temperature α is increased as the required charging time Tchg increases, while the driving time of the compressor 64 is shortened as the required charging time Tchg increases, while heating the passenger compartment 21 when the required charging time Tchg is large. This is to shorten the time required to complete charging when charging the battery 50. In the embodiment, the margin temperature α is set, for example, within a range of 3 ° C. or 5 ° C. or less.

  Further, the battery is heated while heating the passenger compartment 21 based on the temperature difference ΔT (ΔT = | Tin * −Tout |) which is the difference between the set temperature Tin * and the outside air temperature Tout in the air conditioner 60 and the set margin temperature α. The required air conditioning ratio Dair, which is the ratio of the time required to drive the air conditioner 60 per unit time when charging 50, is set (step S130). In the embodiment, the required air conditioning ratio Dair is obtained by previously obtaining the relationship between the temperature difference ΔT, the margin temperature α, and the required air conditioning ratio Dair through experiments or the like and stored in the ROM 74 as an air conditioning required ratio setting map. When the margin temperature α is given, it is set by deriving the corresponding required air conditioning ratio Dair from the map. An example of the air conditioning necessary ratio setting map is shown in FIG. As shown in the figure, the air conditioning required ratio setting map of the embodiment is set so that the air conditioning required ratio Dair increases as the temperature difference ΔT increases, and the air conditioning required ratio Dair decreases as the margin temperature α increases. The reason why the required air conditioning ratio Dair is increased as the temperature difference ΔT increases is based on the fact that the energy necessary for air conditioning in the passenger compartment 21 increases as the temperature difference ΔT increases. As the margin temperature α increases, the required air conditioning ratio Dair decreases because the compressor 64 is driven and stopped at a relatively low load frequently when the margin temperature α is small. When the margin temperature α is large, the frequency of driving and stopping the compressor 64 due to a relatively high load is low, and therefore the driving time of the compressor 64 per unit time is shortened.

  Subsequently, charging as the time required to complete the charging of the battery 50 while heating the passenger compartment 21 at the set temperature Tin * by multiplying the required air conditioning ratio Dair plus the value 1 by the required charging time Tchg Completion required time Tcomp is calculated (step S140), and the calculated charge completion required time Tcomp is displayed on display 80 (step S150). Thereby, the passenger can know the time required to complete the charging of the battery 50.

  Next, the low temperature control temperature Tlow (Tin * −α) is set by subtracting the margin temperature α from the set temperature Tin *, and the high temperature control temperature Thi (Tin * + α) is set by adding the margin temperature α to the set temperature Tin *. Is set (step S160), the compressor 64 is driven (step S170), and the control (steps S180 to S270) for charging the battery 50 while heating the passenger compartment 21 at the set temperature Tin * is started. Here, the compressor 64 controls the AC / DC converter 92 and the DC / DC converter 90 by the hybrid electronic control unit 70 to convert electric power from the commercial power source into DC electric power, and the air conditioning ECU 68 switches the inverter 65. The element can be driven by switching control. Accordingly, the compressor 64 is driven by outputting a control signal for driving the compressor 64 from the hybrid electronic control unit 70 to the air conditioning ECU 68 and driving the AC / DC converter 92 and the DC / DC converter 90. Is output. At this time, the system main relay 56 is in an off state, so that the battery 50 is not charged. For this reason, the electric power from the commercial power source can be sufficiently used for driving the compressor 64.

  In the control for charging the battery 50 while heating the passenger compartment 21 at the set temperature Tin *, first, the CPU 72 of the hybrid electronic control unit 70 inputs the temperature Tin of the passenger compartment 21 and the charged amount SOC of the battery 50 (step). In step S180, a process of determining whether or not the input power storage amount SOC is less than a value Sref that completes charging is executed (step S190). Here, the temperature Tin of the passenger compartment 21 is detected by the temperature sensor 67c of the operation panel 67 and input from the air conditioning ECU 68 by communication.

  When the charged amount SOC of the battery 50 is less than the value Sref, it is determined whether or not the system main relay 56 is turned on (step S200). When the system main relay 56 is turned off, the temperature Tin of the passenger compartment 21 is high. It is determined whether or not the temperature is equal to or higher than the side control temperature Thi (step S250). When the temperature Tin of the passenger compartment 21 is lower than the high side control temperature Thi, the current state, that is, the system main relay 56 is off and the compressor 64 is driven. The process returns to the process of inputting the temperature Tin of the passenger compartment 21 and the charged amount SOC of the battery 50 in step S180. When step S180 and subsequent steps are executed for the first time after executing this heating charge control routine, the system main relay 56 is off and the compressor 64 is in a driving state, and the temperature Tin of the passenger compartment 21 is lower than the high-side control temperature Thi. Thus, the above-described processing is performed.

  When the charged amount SOC of the battery 50 is less than the value Sref, the system main relay 56 is off and the compressor 64 is driven, and the temperature Tin of the passenger compartment 21 reaches the high side control temperature Thi or higher, the driving of the compressor 64 is stopped. (Step S260), the system main relay 56 is turned on (Step S270), and the process returns to the process of inputting the temperature Tin of the passenger compartment 21 and the charged amount SOC of the battery 50 in Step S180. The drive of the compressor 64 is stopped by transmitting a control signal to that effect to the air conditioning ECU 68, and the air conditioning ECU 68 that has received this control signal shuts out the inverter 65 that drives the compressor 64. When the system main relay 56 is turned on, AC power from the commercial power source is converted to DC power by the operation of the AC / DC converter 92 and the DC / DC converter 90, and charging of the battery 50 by this DC power is started. Therefore, the voltage adjustment of the power line 54 by the DC / DC converter 90 may be performed so that the voltage is suitable for charging the battery 50.

  When charging of the battery 50 is started, it is determined in step S190 that the charged amount SOC of the battery 50 is less than the value Sref, and in step S200, it is determined that the system main relay 56 is on. After such determination, the CPU 72 of the hybrid electronic control unit 70 determines whether or not a predetermined time has elapsed since the system main relay 56 was turned on (step S210), and the temperature Tin of the passenger compartment 21 is lower than the low-side control temperature. It is determined whether or not it has become less than Tlow (step S220). Even if a predetermined time has not elapsed since the system main relay 56 was turned on, or even if a predetermined time has elapsed since the system main relay 56 was turned on, the passenger compartment 21 When the temperature Tin has not reached the lower control temperature Tlow, it is determined that the charging of the battery 50 should be continued, and the current state, that is, the system main relay 56 is turned on and the compressor 64 is kept in a driving stopped state. The temperature Tin of the passenger compartment 21 in S180 and the charged amount SO of the battery 50 It returns to the process of inputting. Here, the reason for waiting for a predetermined time after the system main relay 56 is turned on is to avoid frequent on / off of the system main relay 56 and to charge the battery 50 for a predetermined time or more. Therefore, the predetermined time is set as the frequency of ON / OFF of the system main relay 56 and the time longer than the minimum time required for charging the battery 50 relatively efficiently. For example, the predetermined time is 2 minutes, 3 minutes, 5 Times such as minutes can be used.

  When a predetermined time elapses after the system main relay 56 is turned on and the temperature Tin of the passenger compartment 21 becomes lower than the low-side control temperature Tlow, the system main relay 56 is turned off (step S230), and the compressor 64 is driven. (Step S240), the process returns to the process of inputting the temperature Tin of the passenger compartment 21 and the charged amount SOC of the battery 50 in step S180. By this process, the compressor 64 is driven again until the temperature Tin of the passenger compartment 21 reaches the high side control temperature Thi or higher.

  In this way, when the storage amount SOC of the battery 50 reaches the value Sref or more while the charging of the battery 50 and the driving of the compressor 64 are alternately repeated, the system main relay 56 is turned off (step S280), and the commercial power supply Normal air conditioning control during heating by the air conditioning ECU 68 using electric power is executed (step S290), and this routine is terminated.

  Changes in the temperature Tin of the passenger compartment 21 and the amount of charge SOC and the state of the system main relay 56 when the battery 50 is charged with the power plug 94 connected to a commercial power supply and heated by the air conditioner 60 while the system is stopped. An example of this is shown in FIG. As shown in the figure, at time T1, T3, T5 when the temperature Tin of the passenger compartment 21 reaches the high side control temperature Thi or more, the driving of the compressor 64 is stopped and the system main relay 56 is turned on to start charging the battery 50. During the time when the battery 50 is being charged, the system main relay 56 is turned off at times T2 and T4 when the temperature Tin of the passenger compartment 21 has become less than the low-side control temperature Tlow. To drive. Then, at time T6 when the charged amount SOC of the battery 50 reaches the value Sref, the system main relay 56 is turned off to complete charging of the battery 50 and start normal control during heating.

  The cooling charge control routine of FIG. 3 is obtained by applying the heating charge control routine of FIG. 2 to cooling. When the charged amount SOC of the battery 50 is less than the value Sref, the system main relay 56 is turned off and the compressor 64 is turned on. When the temperature Tin of the passenger compartment 21 is lower than the low-side control temperature Tlow (step S250B) in the driving state, the compressor 64 is stopped (step S260) and the system main relay 56 is turned on (step S270). Then, charging of the battery 50 is started, and after a predetermined time has elapsed since the system main relay 56 was turned on and the temperature Tin of the passenger compartment 21 has reached or exceeded the high-side control temperature Thi (step S220B), the system main relay 56 is turned off (step S230), and the compressor Driving the support 64 (step S240). When the charged amount SOC of the battery 50 reaches the value Sref or more, the system main relay 56 is turned off (step S280), and normal air conditioning control during cooling by the air conditioning ECU 68 using electric power from the commercial power source is executed. (Step S290B), this routine ends.

  According to the hybrid vehicle 20 of the embodiment described above, when the battery plug 50 is charged with the power plug 94 connected to the commercial power supply while the system is stopped and the air conditioner 60 is turned on, the set temperature in the air conditioner 60 is set. The margin temperature α is set so as to increase as the temperature difference ΔT (ΔT = | Tin * −Tout |), which is the difference between the Tin * and the outside air temperature Tout, increases as the required charging time Tchg increases. By alternately performing charging of the battery 50 and driving of the compressor 64 of the air conditioner 60 in the range of the margin temperature α from *, the driving time of the compressor 64 is shortened as the temperature difference ΔT increases. The charging time can be secured, and the longer the required charging time Tchg, the more The driving time of the battery 64 can be shortened to shorten the time required to complete charging when charging the battery 50 while heating the passenger compartment 21 when the required charging time Tchg is large. That is, the charging of the battery 50 and the air conditioning of the passenger compartment 21 can be performed more appropriately. In addition, since the charging of the battery 50 is not stopped until a predetermined time has elapsed since the system main relay 56 was turned on, the on / off frequency of the system main relay 56 can be kept appropriate and the battery 50 can be charged relatively efficiently. be able to.

  Further, according to the hybrid vehicle 20 of the embodiment, the charging completion required time Tcomp when the battery 50 is charged with the air conditioner 60 turned on is calculated and displayed on the display 80, whereby the battery 50 The crew can be informed of the time required to complete charging.

  In the hybrid vehicle 20 of the embodiment, the same margin is used as long as the temperature difference ΔT, which is the difference between the set temperature Tin * and the outside air temperature Tout, and the required charging time Tchg are the same during heating and cooling. Although the temperature α is set, even if the temperature difference ΔT and the required charging time Tchg are the same during heating and cooling, different margin temperatures α may be set.

  In the hybrid vehicle 20 of the embodiment, the margin temperature α is set based on the temperature difference ΔT that is the difference between the set temperature Tin * and the outside air temperature Tout and the required charging time Tchg, and the margin temperature α is added to the set temperature Tin *. The high side control temperature Thi is set and the margin temperature α is subtracted from the set temperature Tin * to set the low side control temperature Tlow. However, the temperature difference ΔT, which is the difference between the set temperature Tin * and the outside air temperature Tout, is set. And a margin temperature .alpha. Different from the margin temperature .alpha. Based on the required charging time Tchg, and the high temperature control temperature Thi is set by adding the margin temperature .alpha. To the set temperature Tin *. Decrease margin temperature β from Tin * to set low-side control temperature Tlow, or add margin temperature β to set temperature Tin * The high side control temperature Thi may be set and the low side control temperature Tlow may be set by subtracting the margin temperature α from the set temperature Tin *.

  In the hybrid vehicle 20 of the embodiment, the system main relay 56 is turned off and the compressor 64 is not driven until the predetermined time has elapsed since the system main relay 56 was turned on. However, the predetermined time has elapsed since the system main relay 56 was turned on. Regardless of this, when the temperature Tin of the passenger compartment 21 reaches less than the low-side control temperature Tlow during heating, and when the temperature Tin of the passenger compartment 21 reaches the high-side control temperature Thi or higher during cooling, the system main relay 56 It is good also as what drives the compressor 64 by turning off.

  In the hybrid vehicle 20 of the embodiment, the charging completion time Tcomp when the battery 50 is charged with the air conditioner 60 turned on is calculated and displayed on the display 80. However, the charging completion time Tcomp is calculated. May be output by voice. Moreover, it is good also as what does not alert | report charge completion required time Tcmp. In that case, the charging completion time Tcomp may not be calculated.

The engine 22 is connected to the rotation shaft of the MG via the clutch 329, and the power from the engine 22 is output to the drive shaft via the rotation shaft of the motor MG and the transmission 330 and the power from the motor MG is changed. It is good also as what outputs to a drive shaft via the machine 330. FIG. Alternatively, as illustrated in the hybrid vehicle 420 of the modification of FIG. 11, the power from the engine 22 is output to the axle connected to the drive wheels 39a and 39b via the transmission 430 and the power from the motor MG is driven. It may be output to an axle different from the axle to which the wheels 39a, 39b are connected (the axle connected to the wheels 39c, 39d in FIG. 11).
