[Embodiment 1]
FIG. 1 is a diagram showing a schematic arrangement of components of an automobile 100 according to Embodiment 1 of the present invention.

  Referring to FIG. 1, automobile 100 includes a passenger compartment 25 in which a passenger such as a driver rides, an engine 23 disposed in a front portion in front of passenger compartment 25, a motor generator 24, and an air conditioner. .

  The engine 23 and the motor generator 24 drive the wheels 21. The air conditioner is specifically an air conditioner, and the inside / outside heat exchanger 4, the compressor 5, the electric compressor 6, and the heat exchanger 7 correspond to the “air conditioner”. As the “air conditioner”, a heater heated by engine cooling water may be used.

  The inside / outside heat exchanger 4, the compressor 5, the electric compressor 6, and the heat exchanger 7 are connected by a refrigerant passage 27, and while the engine 23 is operating, the refrigerant is compressed by the compressor 5 and the engine 23 is stopped. The refrigerant is compressed by the electric compressor 6 and circulates in the refrigerant passage.

  At the time of heating, the refrigerant compressed by the compressor 5 or the electric compressor 6 returns from the heat exchanger 7 to the compressor 5 or the electric compressor 6 via the inside / outside heat exchanger 4, so that heat is pumped into the vehicle. Can be put. Further, at the time of cooling, the refrigerant compressed by the compressor 5 or the electric compressor 6 returns to the compressor 5 or the electric compressor 6 via the heat exchanger 7 from the vehicle interior / exterior heat exchanger 4, thereby Is discharged.

  The automobile 100 is a hybrid automobile that drives the vehicle using the engine 23 and the motor generator 24 together. Therefore, automobile 100 further includes battery 1, motor generator 24 and an inverter (not shown). As the battery 1, for example, a nickel metal hydride battery is preferably used.

  Motor generator 24 receives electric energy from battery 1 during powering operation to drive wheel 21, and returns electric energy generated by rotational energy received from wheel 21 to battery 1 during regenerative operation. The inverter mutually converts the direct current of battery 1 and the alternating current of motor generator 24.

  The automobile 100 further includes a wheel 22 that is a rear wheel of the non-driving wheels, a trunk room 18 provided at the rear of the vehicle, a fan 16 that sucks air for adjusting battery temperature from a suction port at the rear of the passenger compartment 25, and a fan 16 The temperature sensor 15 provided in the ventilation path from the battery 1 to the battery 1 and the temperature sensors 11 to 14 attached to the battery 1 are included. As the temperature sensors 11 to 15, for example, thermistors can be used. The air heated or cooled by the heat exchanger 7 is guided to the passenger compartment 25 through the ventilation path 26.

  The battery 1 has an optimum temperature, and when the battery temperature is low at the start-up in an environment where the temperature of outside air is low such as in winter, it is desirable to warm up quickly. For this reason, warm air from the heat exchanger 7 of the air conditioner is directly given to the battery through the passenger compartment. Heat is applied to the battery 1 from warm air through the heat exchange fins 8 formed on the surface of the battery 1.

  Further, in an environment where the temperature of the outside air is high, such as in summer, the air conditioner is operated for cooling, and the cool air from the heat exchanger 7 is directly given to the battery 1 through the passenger compartment. Heat is radiated from the battery 1 through the heat exchange fins 8 formed on the surface of the battery 1 by the cold air.

  FIG. 2 is a block diagram showing a configuration for explaining control of automobile 100.

  Referring to FIG. 2, an automobile 100 includes a battery 1 that uses the air conditioner illustrated in FIG. 1 that air-conditions a passenger compartment 25 for temperature adjustment, and a temperature sensor 15 that operates as a detection unit that detects an operating state of the air conditioner. And an electric device that charges or discharges the battery 1 and a control unit 30 that sets a limit value for the amount of charge or discharge of the battery 1 according to the operating state of the air conditioner.

  The electric device includes an inverter 32 that receives power supply from the battery 1, and a motor 33 and a generator 34 that perform a power running operation or a regenerative operation by the inverter 32. The motor 33 and the generator 34 correspond to the motor generator 24 of FIG.

  The generator 34 receives power from the engine 2 via the planetary gear 36 and generates power. The motor 33 receives the AC output from the inverter 32 and drives the wheels 21 during powering operation. During regenerative operation, the motor 33 generates power by receiving power from the rotation of the wheels 21 or power from the engine 2 via the planetary gear 36.

  The control unit 30 sets a limit value of the output of the motor 33 for the inverter 32. Further, the control unit 30 sets a limit value of the power generation amount of the motor 33 and the generator 34 for the inverter 32.

  FIG. 3 is a flowchart for explaining the control executed by the control unit 30 of FIG. The processing routine of this flowchart from the main routine is executed every predetermined time or every time a predetermined condition is satisfied.

  Referring to FIGS. 2 and 3, when the process is started, in step S <b> 1, the control unit 30 takes in the output of the temperature sensor 15, and the intake air temperature blown to the battery 1 is measured.

  Subsequently, in step S2, the control unit 30 takes in the output of the temperature sensor 11 attached to the battery 1, and the temperature of the battery 1 is measured. In addition, as shown in FIG. 1, when the battery 1 is comprised from several battery units, the control part 30 takes in the output of the several temperature sensors 11-14 sequentially.

  Subsequently, an input / output limit value is calculated from a map predetermined for each intake air temperature in step S3. When the limit value setting process ends, the process proceeds to step S4, and the process returns to the main routine.

  FIG. 4 is a diagram for explaining the map used in step S3 of FIG.

  Referring to FIGS. 2 and 4, control unit 30 refers to maps D <b> 1, D <b> 2... In which limit values determined in advance for each operating state of a plurality of air conditioners are arranged. For example, the operating state of the air conditioner can be determined from the intake air temperature. Map D1 corresponds to an intake air temperature of 25 ° C., and map D2 corresponds to an intake air temperature of 30 ° C. Maps such as maps D1, D2,... Are prepared in advance for both the input limit value and the output limit value, and are stored in a memory inside the control unit 30.

  A map corresponding to the intake air temperature obtained in step S1 of FIG. 3 is selected from the maps D1, D2,.

  Subsequently, a limit value corresponding to the battery temperature obtained in step S2 of FIG. 3 is set.

  In this way, the limit value is set in step S3 of FIG.

  FIG. 5 is a diagram for explaining the limit values of each map shown in FIG.

  Referring to FIG. 5, temperature T3 is a usable upper limit temperature at which the battery is significantly deteriorated. The target upper limit temperature T2 is determined with a certain margin with respect to the usable upper limit temperature T3.

  In each map, the limit value is uniformly set to P1 up to the temperature T1. In the range of temperatures T1 to T3, for example, the limit value W2 when the intake air temperature is 30 ° C. is set to a smaller value than the limit value W1 when the intake air temperature is 25 ° C.

  That is, the predetermined limit value for each operating state of the air conditioner is set to a smaller value in the operating state in which the cooling capacity is lower than in the operating state in which the cooling capacity is high in the predetermined battery temperature range T1 to T3. .

  This is because the cooling capacity is smaller when the intake air temperature is 30 ° C. than when the intake air temperature is 25 ° C. Therefore, the burden on the battery 1 is reduced earlier and the battery is charged so as not to exceed the target upper limit temperature T2. This is because it is better to discharge.

  Therefore, during actual operation, the battery temperature is managed so as not to substantially exceed T2. For this reason, the limit value that is actually applied during operation is rarely a limit value of a temperature close to T3, and is a limit value that substantially corresponds to the battery temperature up to T2.

  When the limit value of the input value is set smaller than P1 between the temperatures T1 and T2, for example, the electric power by the regenerative brake collected by the motor 33 in FIG. Is done. In this case, in order to obtain the same braking force, the ratio of the friction brake (not shown) by the hydraulic pressure is controlled to be larger than when the battery temperature is T1 or less. In this case, the fuel consumption is slightly reduced, but the battery is well protected and the battery life is further extended.

  Further, when the output value limit value is set to be smaller than P1 between temperatures T1 and T2, for example, the time for performing the so-called EV running in which only the motor 33 runs without using the engine 23 is set to the battery temperature. The control is performed so as to be less than when T is less than or equal to T1.

  Another example of the case where the output value limit value is set to be smaller than P1 between temperatures T1 and T2 is, for example, assist running in which the engine 23 is assisted by the motor 33 in order to improve acceleration. Control is performed such that the frequency is lower than when the battery temperature is equal to or lower than T1.

  As a result of such control, optimal control is performed so that charging / discharging of the battery does not exceed the target upper limit temperature of the battery, and as a result, the battery life can be further extended.

  FIG. 9 is a block diagram showing a configuration for explaining control of automobile 100B.

  Referring to FIG. 9, an automobile 100B includes a battery 1 that uses the air conditioner illustrated in FIG. 8 that air-conditions the passenger compartment 25 for temperature adjustment, an air conditioner switch 7B that outputs a signal indicating an operating state of the air conditioner, It includes an electric device that charges or discharges the battery 1 and a control unit 30B that sets a limit value for the amount of charge or discharge of the battery 1 according to the operating state of the air conditioner.

  Otherwise, the switching damper 17B is switched so that the intake air from the passenger compartment 25 is guided to the fan 16.

  FIG. 10 is a flowchart for explaining the control executed by the control unit 30B of FIG. The processing routine of this flowchart from the main routine is executed every predetermined time or every time a predetermined condition is satisfied.

  Referring to FIGS. 9 and 10, when the process is started, in step S11, control unit 30B captures the output of switch 7B, and the operating state of the air conditioner is recognized by control unit 30B.

  Subsequently, in step S12, the control unit 30B takes in the output of the temperature sensor 11 attached to the battery 1, and the temperature of the battery 1 is measured. In addition, as shown in FIG. 8, when the battery 1 is comprised from a some battery unit, the control part 30 takes in the output of the several temperature sensors 11-14 sequentially.

  Subsequently, in step S13, an input / output limit value is calculated from a map determined in advance for each operating state of the air conditioner. When the limit value setting process ends, the process proceeds to step S14, and the process returns to the main routine.

  FIG. 11 is a diagram for explaining the map used in step S3 of FIG.

  Referring to FIGS. 9 and 11, control unit 30 </ b> B refers to maps D <b> 3 and D <b> 4 in which limit values determined in advance for each operating state of a plurality of air conditioners are arranged.

Maps such as maps D3 and D4 are prepared in advance for both the input limit value and the output limit value, and are stored in the internal memory of the control unit 30B.

  A map corresponding to the operating state obtained in step S11 of FIG. 10 is selected from the maps D3 and D4. Specifically, the map D3 is selected if the air conditioner switch 7B is on, and the map D4 is selected if it is off.

  Subsequently, a limit value corresponding to the battery temperature obtained in step S12 of FIG. 10 is set.

  In this way, the limit value is set in step S13 of FIG.

  FIG. 12 is a diagram for explaining the limit values of each map shown in FIG.

Referring to FIG. 12, the temperature T6 is usable upper limit temperature that degradation of the battery becomes significantly. The target upper limit temperature T5 is determined with a certain margin with respect to the usable upper limit temperature T6.

  In each map, the limit value is uniformly set to P2 up to the temperature T4. In the range of temperatures T4 to T6, for example, the limit value W4 when the air conditioner is off is set to a smaller value than the limit value W3 when the air conditioner is on.

  In other words, the predetermined limit value for each operating state of the air conditioner is set to a smaller value in the operating state in which the cooling capacity is lower than in the operating state in which the cooling capacity is high in the predetermined battery temperature range T4 to T6. .

  This is because the cooling capacity of the air conditioner is smaller when the air conditioner is turned off than when the air conditioner is turned on. Therefore, the load on the battery 1 is reduced earlier and the battery is charged / discharged so as not to exceed the target upper limit temperature T2. This is because it is better to do.

  Therefore, during actual operation, the battery temperature is managed so as not to substantially exceed T5. For this reason, the limit value that is actually applied during operation is rarely a limit value of a temperature close to T6, and is a limit value that substantially corresponds to the battery temperature up to T5.

  When the limit value of the input value is set smaller than P2 between the temperatures T4 and T5, for example, the electric power by the regenerative brake collected by the motor 33 in FIG. Is done. In this case, in order to obtain the same braking force, the ratio of the friction brake (not shown) by the hydraulic pressure is controlled to be larger than when the battery temperature is T4 or less. In this case, the fuel consumption is slightly reduced, but the battery is well protected and the battery life is further extended.

  Further, when the output value limit value is set to be smaller than P2 between temperatures T4 and T5, for example, the time for performing the so-called EV running in which only the motor 33 is run without using the engine 23 is set to the battery temperature. Is controlled to be less than when T is less than or equal to T4.

  Another example of the case where the limit value of the output value is set to be smaller than P2 between temperatures T1 and T2 is, for example, assist running in which the engine 23 is assisted by the motor 33 in order to improve acceleration. Control is performed such that the frequency is lower than when the battery temperature is T4 or less.

  As a result of such control, optimal control is performed so that charging / discharging of the battery does not exceed the target upper limit temperature of the battery, and as a result, the battery life can be further extended.

  In the second embodiment, the on / off of the air conditioner switch 7B is described as an example as information directly indicating the operating state of the air conditioner. This information may be transmitted to the control unit 30B or the switching damper 17B by an electrical signal, but the switching damper 17B may be switched by a mechanism that switches according to the physical setting of the switch. Further, for example, the limit value may be set based on information on the set temperature for the air conditioner, instead of the on / off signal.

  As described above, also in the second embodiment, optimal control is performed so that charging / discharging of the battery does not exceed the target upper limit temperature of the battery, and as a result, the battery life can be further extended.

The embodiment disclosed this time should be considered as illustrative in all points and not restrictive.
