Description

  The present invention relates to a charge control device for a hybrid vehicle.

  Conventionally, in the stage before the start of traveling of the vehicle, the vehicle interior is warmed or cooled using an air conditioner (pre-traveling air conditioning operation). In this way, a safe and comfortable drive can be performed from the time of departure without leaving the vehicle in an extremely uncomfortable situation in the morning or summer in winter.

  By the way, in a hybrid vehicle using an engine and an electric motor as a driving source for the vehicle, the air conditioner is operated by the electric energy of the battery for the electric motor. However, when the charge amount of the battery is small, the engine starts automatically. Some batteries are designed to store electricity in the battery.

  Thus, in order to operate the air conditioner before the start of traveling of the vehicle, if electric energy for operation is generated by the engine, fuel is consumed, resulting in a decrease in fuel consumption.

  In view of the above points, the present invention aims to reduce the necessity of starting an engine and generating electric energy for operating an air conditioner even when the air conditioner is operated before the vehicle starts to travel. To do.

  In order to achieve the above object, the invention according to claim 1 is a charge amount control for controlling a charge amount of a battery for the motor in a hybrid vehicle that travels using an engine that is an internal combustion engine and a motor that is an electric motor as drive sources. The device is a device that records a registered place in a storage medium (23) as a place for performing a pre-travel air conditioning operation in which an air conditioner is actuated in advance to bring the vehicle interior to an appropriate temperature before traveling the hybrid vehicle. Learning means (200) for recording, in the storage medium (23), the time at which the hybrid vehicle is parked at the registration location as a registration time B before performing the pre-travel air conditioning operation at the registration location; The time zone including the registration time B is calculated based on the fact that the vehicle enters from outside the area within a predetermined set distance from the Judging means (320, 330, 340) for judging whether or not an approach time when the vehicle enters from outside the area within the predetermined set distance from the registered place is within the calculated time zone; When the determination means determines that the entry time is within the time zone, the charge amount of the motor battery is controlled so as to be within a predetermined first range. And a control means (350) for controlling the charge amount of the battery to fall within a second range in which an upper limit and a lower limit are larger than the first range.

  In this way, a place where there is a high possibility of performing the pre-travel air-conditioning operation is recorded as a registered place, and the time at which the vehicle is parked at the registered place before performing the pre-travel air-conditioning operation at the registered place is recorded as the registered time B. Then, when the hybrid vehicle approaches the registration location and the approach time is within a time zone including the registration time B, the charge amount control device performs air conditioning before traveling after the hybrid vehicle is parked at the registration location. It is predicted that the operation will be performed, and control is performed so that the charge amount of the battery for the motor falls within the second range in which the upper limit and the lower limit are larger than the first range.

  In this way, even if the air conditioning operation before traveling is performed next time at the registration location, the charge amount of the battery is larger than usual, so the engine is started at that time and the air conditioner is operated. The need to generate electrical energy for use is reduced.

  Further, in the invention according to claim 2, the learning means further records a time at which the pre-travel air conditioning operation is performed at the registration place as a registration time A in the storage medium (23), and the determination means (320, 330). 340) is a time based on the registration time A, starting from a time based on the registration time B based on the hybrid vehicle entering from outside the area within a predetermined set distance from the registration location. The charge amount control device according to claim 1, wherein a time zone having an end point as a destination is calculated, and it is determined whether or not the entry time is within the calculated time zone.

  In this way, the time at which the pre-travel air-conditioning operation is performed at the registration location is recorded as the registration time A, and the time zone starting from the time based on the registration time B and ending at the time based on the registration time A is defined as the entry time. It comes to compare.

  According to the inventor's study, even if the vehicle returns to the registration location at a time that is too much of the registration time B that is assumed to park the hybrid vehicle at the registration location before performing the pre-travel air conditioning operation at the registration location, If the time is around the registration time A where the pre-travel air-conditioning operation is supposed to start or before the registration time A, the possibility of performing the pre-travel air-conditioning operation at the departure is also high. Therefore, the charge amount can be controlled more efficiently by doing in this way.

  According to a third aspect of the present invention, the time when the pre-travel air-conditioning operation is performed, the position of the hybrid vehicle at the time, and the IG off time immediately before the pre-travel air-conditioning operation are performed, respectively. The learning is provided with a pre-travel air-conditioning operation recording means (100) that repeatedly executes a process of recording in the storage medium (23) as one pre-travel air-conditioning operation record as the operation time, the pre-travel air-conditioning operation location, and the immediately preceding off time. The means (200) includes a plurality of pre-travel air conditioning operation records recorded in the storage medium (23) by the pre-travel air conditioning operation recording means (100) repeatedly executing the pre-travel air conditioning operation recording process. Based on the above, a plurality of pre-travel air-conditioning operation records in which the pre-travel air-conditioning operation location and the pre-travel air-conditioning operation time are concentrated over a predetermined standard are extracted and extracted. The representative position of the pre-travel air conditioning operation location in the plurality of pre-travel air conditioning operation records is recorded in the storage medium (23) as the registered location, and the representative time of the immediately preceding off time in the extracted pre-travel air conditioning operation records The charge amount control apparatus according to claim 1 or 2, wherein a time range centering on the time range is set and a past boundary of the time range is recorded in the storage medium (23) as the registered time B. is there.

  Thus, based on the time when the actual air conditioning operation before traveling is performed, the position of the hybrid vehicle at the time, and the IG off time immediately before performing the air conditioning operation before traveling, the registration location and the registration time are statistically calculated. Since B is calculated, the driver does not have to input the location and time as the registration location and registration time B by himself / herself, and the convenience is increased accordingly.

  According to a fourth aspect of the present invention, the pre-travel air conditioning operation recording means (100) keeps the hybrid vehicle stopped for a set time or more after the IG is turned on in the pre-travel air conditioning operation recording process, and Based on the fact that the air conditioner of the hybrid vehicle is operating and the difference between the set temperature of the air conditioner and the outside air temperature outside the hybrid vehicle is greater than or equal to a reference value, the hybrid when the IG is on The vehicle position, the time when the IG is turned on, and the time when the IG is turned off immediately before the IG is turned on are the air conditioning operation place before traveling, the air conditioning operation time before traveling, and the immediately off time, respectively. The pre-air conditioning operation time and the immediately preceding off time are recorded in the storage medium (23) as one pre-travel air conditioning operation record. Claims 1 a charge amount control apparatus according to any one of the three.

  Thus, based on the time when the actual air conditioning operation before traveling is performed, the position of the hybrid vehicle at the time, and the IG off time immediately before performing the air conditioning operation before traveling, the registration location and the registration time are statistically calculated. Since B is calculated, the driver does not have to input the location and time as the registration location and registration time B by himself / herself, and the convenience is increased accordingly.

  According to a fifth aspect of the present invention, the determination means (320, 330, 340) is based on the hybrid vehicle entering from outside the area within a predetermined set distance from the registered location. The estimated time required for arrival of the hybrid vehicle at the registered location is calculated, and the time that is traced back by the estimated time required for arrival with respect to the registration time B as the starting point, and within the time zone with the registration time A as the end point. The charge amount control device according to claim 1, wherein it is determined whether or not an approach time has been entered. In this way, charging control can be performed with higher accuracy by calculating the start point of the time zone in consideration of the estimated time required for arrival at the registered location of the vehicle.

  According to a sixth aspect of the present invention, there is provided a program used for a charge amount control device for controlling a charge amount of a battery for a motor in a hybrid vehicle that travels using an engine that is an internal combustion engine and a motor that is an electric motor as drive sources. Then, the charge amount control device records the registration location in the storage medium (23) as a location for performing the pre-travel air conditioning operation for operating the air conditioner in advance to bring the vehicle interior to an appropriate temperature before traveling the hybrid vehicle. Further, a learning means (200) for recording in the storage medium (23) as a registration time B a time when the hybrid vehicle is parked at the registration location before performing the pre-travel air conditioning operation at the registration location, A time zone including the registration time B is calculated based on entering from outside the area within a predetermined set distance from the registration location. Judgment means (320, 330, 340) for judging whether or not the approach time when the hybrid vehicle enters from outside the area within the predetermined set distance from the registered place is within the calculated time zone. ), And when the determination means determines that the entry time is within the time period, from the state where the amount of charge of the battery for the motor is controlled to be within a predetermined first range, This is a program that functions as control means (350) for controlling the amount of charge of the motor battery to fall within a second range in which the upper limit and the lower limit are larger than the first range.

  The first embodiment of the present invention will be described below. FIG. 1 schematically shows an example of the configuration of a hybrid vehicle to which the present embodiment is applied. The hybrid vehicle includes an engine 1, a generator 2, a motor 3, a differential device 4, tires 5a, tires 5b, an inverter 6, a DC link 7, an inverter 8, a battery 9, an HV control unit 10, a position detector 11, An air conditioner ECU 12, an air conditioner 13, an outside air temperature sensor 14, and a charge amount control device 20 are mounted.

  This hybrid vehicle runs using the engine 1 and the motor 3 as power sources. When the engine 1 is used as a power source, the rotational force of the engine 1 is transmitted to the tires 5a and 5b via a clutch mechanism and a differential device 4 (not shown). When the motor 3 is used as a power source, the DC power of the battery 9 for operating the motor 3 is converted into AC power via the DC link 7 and the inverter 8, and the motor 3 is operated by the AC power. The rotational force of the motor 3 is transmitted to the tires 5a and 5b via the differential device 4.

  The rotational force of the engine 1 is also transmitted to the generator 2, and the generator 2 generates AC power by the rotational force, and the generated AC power is converted into DC power via the inverter 6 and the DC link 7. The DC power may be stored in the battery 9 in some cases. Such charging of the battery 9 is charging by the operation of the engine 1 using fuel. Hereinafter, this type of charging is referred to as internal combustion charging.

  Further, when the hybrid vehicle decelerates by a braking mechanism (not shown), a resistance force at the time of deceleration is applied to the motor 3 as a rotational force, and the motor 3 generates AC power by this rotational force. It is converted into direct current power via the DC link 7, and the direct current power is stored in the battery 9. Hereinafter, this type of charging is referred to as regenerative charging.

  The HV control unit 10 controls the generator 2, the motor 3, the inverter 6, the inverter 8, and the battery 9 so that the amount of charge of the battery 9 (that is, the remaining amount, the same shall apply hereinafter) falls within the range from the lower limit value to the upper limit value. Control execution / non-execution of such operations. The HV control unit 10 may be realized using a microcomputer, for example, or may be hardware having a dedicated circuit configuration for realizing the following functions.

  More specifically, the HV control unit 10 stores three values of an upper limit SOC, a lower limit SOC, and a current SOC, and performs an operation based on the upper limit SOC, the lower limit SOC, and the current SOC. The SOC (Status of Charge) is an index representing the amount of charge of the battery, and the higher the value, the greater the amount of charge. The current SOC indicates the current SOC of the battery 9. The HV control unit 10 repeatedly updates the current SOC value by sequentially detecting the state of the battery 9.

  Further, the HV control unit 10 keeps the current SOC within the range from the upper limit SOC to the lower limit SOC while the hybrid vehicle is traveling. The vehicle is driven by the engine 1, the vehicle is driven by the motor 3, the internal combustion charging, and the regenerative charging. Switching between execution and non-execution for each of.

  For example, when the current SOC falls below the lower limit SOC, the internal combustion charging is used to convert the fuel energy into electric power energy, which is stored in the battery 9. When the current SOC exceeds the upper limit SOC, the hybrid vehicle is driven using the power of the motor 3 as a main power source, thereby reducing the charge amount of the battery 9.

The initial values of the upper limit SOC and the lower limit SOC are recorded in a non-volatile storage medium (for example, ROM) of the HV control unit 10, and after the operation of the HV control unit 10 starts, the upper limit SOC and the lower limit SOC are Unless an instruction to change the lower limit SOC is received, these initial values are used as the upper limit SOC and the lower limit SOC. (Initial values of the upper limit SOC and the lower limit SOC are, for example, 70% and 30%, assuming a fully charged state as 100%)
However, when receiving the change command for the upper limit SOC and the lower limit SOC from the charge amount control device 20, the HV control unit 10 changes the upper limit SOC and the lower limit SOC according to the contents of the change command.

  The position detector 11 is a well-known sensor group for specifying the current position of the vehicle, the traveling direction, the traveling speed, and the like, such as a GPS receiver, a vehicle speed sensor, an acceleration sensor, and a gyro sensor.

  The air conditioner ECU 12 is a device that controls the air conditioner 13 for cooling and heating the passenger compartment of the hybrid vehicle. The air conditioner ECU 12 controls the air conditioner 13 so that the air temperature in the vehicle interior maintains the set temperature. The set temperature may be acquired by a method of receiving a user input using a temperature setting operation unit (not shown) (for example, a button), or may be automatically determined by another method. The air conditioner ECU 12 is configured to repeatedly output the current set temperature to the charge amount control device 20 periodically (for example, every second) as to whether or not the air conditioner 13 is in operation. .

  The outside air temperature sensor 14 is a sensor that detects the temperature outside the hybrid vehicle (around the hybrid vehicle) (that is, the outside air temperature) and outputs the detected outside air temperature as a detection signal.

  The charge amount control device 20 outputs an instruction to change the upper limit SOC and the lower limit SOC to the HV control unit 10 as necessary based on signals received from the position detector 11 and the air conditioner ECU 12, thereby charging the battery 9 It is a device that controls.

  As shown in FIG. 2, the charge amount control device 20 includes a RAM 21, a ROM 22, a storage medium 23 for storing data and a control unit 24. The storage medium for storage 23 is a storage medium that can continue to hold data even when the main power supply of the charge amount control device 20 is stopped. For example, the storage medium 23 is a non-volatile storage medium such as a hard disk, flash memory, or EEPROM. Any one of the backup RAMs can be employed.

  The control unit 24 executes the program read from the ROM 22 or the storage medium for storage 23, reads information from the RAM 21, the ROM 22, and the storage medium for storage 23 when executing the program, and stores the information into the RAM 21 and the storage medium for storage 23. Information is written, and signals are exchanged with the HV control unit 10, the position detector 11, the air conditioner ECU 12, the air conditioner 13, and the outside air temperature sensor 14. Specifically, the control part 24 implement | achieves processes, such as a pre-travel air-conditioning driving | operation recording process 100, the learning process 200, and the monitoring process 300, by running a predetermined program.

  First, the pre-travel air conditioning operation recording process 100 will be described. The charge amount control device 20 operates by receiving power supply from a battery (the battery 9 or another battery may be used) even when the IG and ACC of the vehicle are turned off. During operation, the pre-travel air conditioning operation recording process 100 is always executed.

  FIG. 3 shows a flowchart of the pre-travel air conditioning operation recording process 100. First, in step 110, the control unit 24 determines whether or not the IG of the hybrid vehicle has changed from on to off, and if it determines that the IG of the hybrid vehicle has not changed from on to off, the control unit 24 proceeds to step 130, where the IG It is determined whether or not it has changed from off to on, and if it is determined that it has not changed from off to on, the process returns to step 110. Therefore, as long as IG does not change, the determination processing of step 110 and step 130 is repeated.

  For example, when the hybrid vehicle travels to the driver's home at night and arrives at the home and the IG is turned off by the driver's operation, it is determined in step 110 that the IG has been turned off from on, and then the process proceeds to step 120. In step 120, the current time is recorded in the storage medium for storage 23 as the IG off time, and the process proceeds to step 130.

  Subsequent to step 120, the determination processing of step 130 and step 110 is repeated until IG changes from off to on. For example, the next morning, the driver gets on the vehicle and turns on the IG. Then, the control unit 24 determines in step 130 that the IG has changed from off to on, proceeds to step 140, and starts counting time.

  Subsequently, in step 150, based on the signal from the position detector 11, it is determined whether the vehicle speed of the hybrid vehicle is greater than 0 km, that is, whether the vehicle is traveling. If it is determined that it is greater than 0 km, the process returns to step 110.

  If it is determined that the vehicle speed is not greater than 0 km (that is, the hybrid vehicle is stopped), the routine proceeds to step 160. In step 160, it is determined whether or not the set time has elapsed since the start of time counting in step 140. If it is determined that the time has not elapsed, the process returns to step 150.

  Here, the set time is a time for determining whether or not the hybrid vehicle has stopped for about the time normally required to perform the pre-travel air conditioning operation after the IG is turned on, for example, 10 minutes.

  The air conditioning operation before traveling means that the air conditioner 13 is operated in advance to bring the interior of the vehicle to an appropriate temperature before traveling the hybrid vehicle. For example, a pre-travel air conditioning operation (warm-up operation) may be performed at a low temperature such as in the winter morning, and a pre-travel air conditioning may be performed at a high temperature such as in the summer. May drive.

  As a method for performing the air conditioning operation before traveling, for example, an air conditioning operation start method by an operation in the passenger compartment may be used, or an air conditioning operation start method by a remote operation outside the passenger compartment may be used.

  In the former case, the driver gets on the hybrid vehicle, turns on the IG, operates a predetermined air conditioning operation unit (not shown), and gives the air conditioning ECU 12 an operation start command and set temperature of the air conditioning device 13. Input to the air conditioner ECU 12. Then, the air conditioner ECU 12 starts the operation of the air conditioner 13 and controls the air conditioner 13 so as to bring the passenger compartment closer to the set temperature.

  In the latter case, the driver operates a wireless communication device (not shown) outside the passenger compartment (for example, indoors), and transmits an operation start command and set temperature of the air conditioner 13 to the air conditioner ECU 12 having a wireless communication function. Receiving this, the air conditioner ECU 12 starts the operation of the air conditioner 13 and controls the air conditioner 13 so as to bring the passenger compartment closer to the set temperature.

  The air conditioner 13 operates by receiving power supply from the battery 9. Therefore, the HV control unit 10 monitors the current SOC of the battery 9 so that the battery 9 does not decrease excessively, and starts the engine 1 when the current SOC falls below a predetermined reference value (for example, 30%). When the engine 1 is started, the HV control unit 10 performs control for maintaining the battery 9 between the upper limit SOC and the lower limit SOC, so that the charge amount of the battery 9 is stabilized.

  However, if the engine 1 is operated in order to operate the air conditioner 13, fuel is consumed, resulting in a reduction in fuel consumption. Further, if the engine is operated while the hybrid vehicle is stopped, exhaust gas, noise, and the like increase the risk of adversely affecting the surroundings of the hybrid vehicle. Therefore, in the pre-travel air conditioning operation, it is not desired to operate the engine 1 as much as possible.

  Returning to the description of steps 150 and 160 in FIG. After IG is turned on, the processes of steps 150 and 160 are repeated until the vehicle starts running or until a set time elapses after IG is turned on.

  When the hybrid vehicle does not perform the pre-travel air conditioning operation, the hybrid vehicle almost always starts traveling before the set time elapses. In such a case, the process returns from step 150 to step 110.

  In addition, even if the hybrid vehicle is not performing the pre-travel air conditioning operation, if the set time has elapsed with the hybrid vehicle stopped for other reasons, and the hybrid vehicle is performing the pre-travel air conditioning operation, the hybrid vehicle is If the set time has passed with the operation stopped, the process proceeds from step 160 to step 170.

  In step 170, based on the above-mentioned signal from the air conditioner ECU 12, whether or not the air conditioner 13 is operating and the current set temperature are specified. Further, by acquiring a detection signal from the outside air temperature sensor 14, the outside air temperature outside the hybrid vehicle and around the hybrid vehicle is specified.

  Subsequently, in step 180, it is determined whether or not the condition that “the air conditioner 13 is operating and the absolute value of the difference between the set temperature and the outside air temperature is equal to or greater than a predetermined threshold temperature difference (for example, 10 degrees)” is satisfied. . And when it determines with satisfy | filling, it progresses to step 190, and when it determines with not satisfy | filling, it returns to step 110.

  When the pre-travel air conditioning operation is not performed, the difference between the set temperature and the outside air temperature is almost not large even if the air conditioner 13 is not operating or is operating. On the other hand, when the air conditioning operation before traveling is performed, the air conditioner 13 is naturally operating, and the difference between the set temperature and the outside air temperature is mostly large. Therefore, most of the cases proceeding from step 180 to 190 are when the pre-travel air conditioning operation is being performed.

  In step 190, the position of the hybrid vehicle when the IG is turned on, the time when the IG is turned on, and the time when the IG is turned off immediately before the IG is turned on. The time is additionally recorded in the storage medium 23 for storage as one pre-travel air conditioning operation record.

  As the position of the hybrid vehicle when the IG is turned on this time, the current position of the hybrid vehicle specified based on the signal from the position detector 11 at the time of step 190 is adopted. The time when the IG is turned on may be the time when it is determined in step 130 that the IG is turned on, or the current time at the time of step 190 may be adopted. This is because the accuracy of the IG-on time is about 10 minutes. As the IG off time immediately before the IG on, the IG off time recorded on the storage medium 23 for storage last is employed. After step 190, the process returns to step 110.

  Thus, in the pre-travel air conditioning operation recording process 100, the hybrid vehicle remains stopped for a set time after the IG is turned on (steps 150 and 160), the hybrid vehicle air conditioner is in operation, and Based on the fact that the difference between the set temperature of the air conditioner and the outside air temperature outside the hybrid vehicle is greater than or equal to a reference value (step 180), the position of the hybrid vehicle when the IG is on, the time when the IG is on , And the IG OFF time immediately before the IG ON is recorded in the storage medium 23 for storage as one pre-travel air conditioning operation record as the pre-travel air conditioning operation location, the pre-travel air conditioning operation time, and the immediately prior OFF time, respectively ( Step 190). Each time the hybrid vehicle performs an operation of parking → IG on → pre-travel air conditioning operation, the processes of steps 110 to 190 are repeated, and one pre-travel air conditioning operation record is additionally recorded. As a result, a plurality of pre-travel air conditioning operation records are stored in the storage medium 23 for storage. The pre-travel air conditioning operation record includes the date and time when the pre-travel air conditioning operation record was recorded.

  Next, the learning process 200 will be described. FIG. 4 shows a flowchart of the learning process 200. The control unit 24 executes the learning process 200 periodically (for example, at intervals of two weeks).

  In each learning process 200, the pre-travel air-conditioning operation record recorded in the storage medium 23 is a predetermined period from the present (for example, two weeks, one week, or one month). Only the pre-travel air-conditioning operation records recorded after the date and time of retrogress are extracted as targets, and the processing of steps 210 to 240 is performed. Therefore, in the following description of the learning process 200, the pre-travel air-conditioning operation record refers to a pre-travel air-conditioning operation record recorded after the date and time that has been traced back for a predetermined period from the present.

  First, in step 210, as shown in FIG. 5, for each of a plurality of geographic areas (4 × 4 = 16 geographic areas in FIG. 5) partitioned by about 10 meters in length and width, the one geography If the number of pre-travel air-conditioning operation records having the pre-travel air-conditioning operation location in the area is calculated and the calculated number is equal to or more than a predetermined first set number of times (for example, 4 times), the pre-travel in the one geographical area The pre-travel air-conditioning operation records having the air-conditioning operation place equal to or more than the first set number of times are extracted as a record group in the same area.

  For example, in the example of FIG. 5, a white circle represents one pre-travel air-conditioning operation record, and there are four pre-travel air-conditioning operation records 31 a to 31 d having a pre-travel air-conditioning operation location in the geographic area 31. These pre-travel air conditioning operation records 31a to 31d are extracted as a group of records in the same area. Further, since there are four or more pre-travel air-conditioning operation records having the pre-travel air-conditioning operation location in the geographic area 32, these pre-travel air-conditioning operation records are one and the same, separately from the pre-travel air-conditioning operation records 31a to 31d. Extracted as a group of records in the area.

  Subsequently, in step 220, for each of the same-area record groups extracted in step 210, a pre-travel air-conditioning operation record having a pre-travel air-conditioning operation time within a certain time zone is stored in the same-area record group. When there are two set times (for example, four times) or more, the pre-travel air conditioning operation records having the pre-travel air conditioning operation time within the one time zone and the second set times or more are recorded in the same region / time zone. Extract as an internal record group.

  For example, with respect to the group of records in the same area corresponding to the extracted section 32 in FIG. 5, a time zone of one hour unit is set by equally dividing 24 hours into 24, and each of the time zones 1 The number of pre-travel air-conditioning operation records having the pre-travel air-conditioning operation time within the time zone is calculated within the same area record group. As a result, for example, as shown in FIG. 6A, when there are 11 pre-travel air-conditioning operation records 35a to 35k having the pre-travel air-conditioning operation time in the time zone 35 (which is equal to or greater than the second set number of times). Extracts the 11 pre-travel air conditioning operation records as a group of records in the same region / time zone.

  By executing the processing of steps 210 and 220, a plurality of pre-travel air conditioning operation records in which the pre-travel air conditioning operation location and the pre-travel air conditioning operation time are concentrated more than a predetermined reference are recorded in the same area / time zone record. Can be extracted as a group. There may be one record group or two or more record groups within the same region / time zone that can be extracted.

  Subsequently, in step 230, for each record group in the same region / time zone extracted in step 220, a representative position of the pre-travel air conditioning operation location in the pre-travel air conditioning operation record belonging to the same region / time zone record group is calculated. To do. For example, the center-of-gravity position (corresponding to positions 31e and 32a in FIG. 5) of the pre-travel air-conditioning operation place in the record group in the same region / time zone may be used as the representative position, or One of them (for example, the pre-travel air-conditioning operation location in the last recorded pre-travel air-conditioning operation record) may be used as the representative position.

  At the same time, in step 230, for each record group in the same region / time zone extracted in step 220, the representative time of the pre-travel air conditioning operation time in the pre-travel air conditioning operation record belonging to the same region / time zone record group is calculated. To do. For example, the average time of the pre-travel air conditioning operation time in the pre-travel air conditioning operation record belonging to the same area / time zone record group may be used as the representative time.

  Alternatively, taking the same area / time zone record groups 35a to 35k as an example, as shown in FIG. 6B, the time zone 35 corresponding to the same area / time zone record groups 35a to 35k is further detailed. Subdivided into small time zones (for example, time zones in units of 15 minutes), and for each of the small time zones, the same number of pre-travel air conditioning operation records having the pre-travel air conditioning operation time included in the small time zone The calculation is performed within the area / time zone record groups 35a to 35k. The central time 36a of the small time zone 36 in which the number of air-conditioning operation records before traveling is the largest may be used as the representative time.

  In step 230, the calculated representative position is recorded on the storage medium for storage 23 as a registration location, and the calculated representative time is recorded on the storage medium for storage 23 as a registration time A.

  Subsequently, in step 240, for each of the record group in the same region / time zone extracted in step 220, the registration time B based on the immediately preceding off time in the pre-travel air conditioning operation record belonging to the record group in the same region / time zone. Is calculated and recorded in the storage medium 23 for storage.

  For example, taking the record groups 35a to 35k in the same area / time zone of FIG. 6 as an example, as shown in FIG. 7, a time zone is set in which 24 hours are equally divided into 24 × 4 = 96 in 15-minute units. Then, for each of the time zones, the number of pre-travel air-conditioning operation records having the immediately preceding off time included in the time zone is calculated within the same area / time zone record groups 35a to 35k. And the time range 38 centering on the central time 37a of the time slot | zone 37 with the largest number of the air-conditioning operation records before driving | running | working is set, and the past boundary 39 of the said time range is set to the storage medium 23 for storage as the registration time B. Record. Here, the length of the time range 38 is set to a larger value as the variation in the immediately preceding off time in the record group 35a to 35k in the same region / time zone increases, for example, three times the standard deviation σ of the immediately preceding off time. Or a length corresponding to a significance level of 20%. The central time 37a may be an average value of off times in the same area / time zone record groups 35a to 35k.

  Note that the registration location, registration time A, and registration time B calculated in steps 230 and 240 in this way are stored for each record group in the same area / time zone that is the source of the calculation, and a storage medium for storage 23. After step 240, one learning process 200 is completed.

  As described above, in steps 230 and 240, for each record group in the same region / time zone, a registered place is recorded as a place assumed to perform the pre-travel air conditioning operation, and the pre-travel air conditioning operation is performed at the registered location. The assumed time is recorded as registration time A, and the time assumed to park the hybrid vehicle at the registration location immediately before performing the pre-travel air conditioning operation at the registration location is recorded as registration time B.

  When the learning process 200 is executed a certain time, the registration location, registration time A, and registration time B recorded in the storage medium for storage 23 when the previous learning process 200 is executed are all deleted. By doing so, the possibility that the registration location, the registration time A, and the registration time B are too old as information and do not match the actual situation is reduced.

  Next, the monitoring process 300 will be described. The control unit 24 always executes the monitoring process 300 while the vehicle is traveling. FIG. 8 shows a flowchart of the monitoring process 300.

  First, in step 310, it is determined whether or not learning is completed. Specifically, it is determined whether or not one or more sets of registration location, registration time A, and registration time B are recorded in the storage medium 23 for storage. While the learning is not completed, step 310 is repeated, and if it is determined that the learning is completed, the process proceeds to step 320.

  In step 320, based on the signal from the position detector 11, the radius centered on one of the registered locations recorded in the storage medium for storage 23 is set from the outside to the inside of the circle having the set distance (for example, about 2 km). It is determined whether or not a hybrid vehicle has entered. If not, the process of step 320 is repeated. If it is determined that the hybrid vehicle has entered, the process proceeds to step 330.

  For example, as shown in FIG. 9, when a location at home is recorded as the registration location 31 e, the hybrid vehicle 40 enters from the outside of a circle 42 whose radius centered on the registration location 31 e is a set distance 41. Then, it is determined in step 320 that the process has entered, and the process proceeds to step 330.

  The set distance corresponds to the travel distance required to increase the charge amount of the battery 9 from the current lower limit SOC to the target SOC (the lower limit SOC of the second range described later) by internal combustion charging. Therefore, the set distance is determined according to the performance of the engine 1, the performance of the battery 9, and the like. Further, the set distance may be changed according to the current outside air temperature.

  Subsequently, in step 330, an expected arrival time for the hybrid vehicle to the registered place is calculated. As the estimated arrival time, a result obtained by dividing a linear distance from the current position to the registered place by a predetermined speed (for example, 30 km / h or an average value of the vehicle speed of the hybrid vehicle in the past 10 minutes) may be adopted. If the charge amount control device 20 stores the road map data for the navigation device, the route from the current position to the registered location is calculated based on the road map data, and the calculated route is along the calculated route. A result obtained by dividing the distance by the predetermined speed may be adopted.

  Subsequently, in step 340, a control target time is set. Specifically, as shown in FIG. 10, the time zone starting from the time 44 that is back by the expected arrival time 45 with respect to the registration time B (49) as the start point and the time zone having the registration time A (36a) as the end point is controlled. The target time is 46.

  Further, in step 340, whether or not the time when the hybrid vehicle has entered from outside the area (inside the circle) within a predetermined set distance from the registered location (that is, the entry time) is within this control target time 46. If YES in step 350, the flow advances to step 350. If not, the flow returns to step 320 and waits until the ball enters a circle from outside the registration center.

  In step 350, charge control is performed. FIG. 11 shows a flowchart of this charging control. In the charge control, first, in step 351, the target control range of the charge amount of the battery 9 is changed. Specifically, an upper limit SOC and lower limit SOC change command is output to the HV control unit 10. The changed upper limit SOC included in the change command is larger than the initial value upper limit SOC in the HV control unit 10, and the changed lower limit SOC included in the change command is the initial value lower limit SOC in the HV control unit 10. Bigger than. For example, the changed upper limit SOC and lower limit SOC are 90% and 50%, respectively.

  When such a change command for the upper limit SOC and the lower limit SOC is output to the HV control unit 10, the HV control unit 10 determines the current upper limit SOC and lower limit SOC (that is, the upper limit SOC and the lower limit SOC of the initial value) Change to the upper limit SOC and lower limit SOC after the change included in the change command. Thereby, as shown in FIG. 12, the range 61 from the upper limit SOC to the lower limit SOC of the initial value is the target control range. By receiving the change command, from the upper limit SOC after the change to the lower limit SOC. The range 62 becomes a new target control range.

  And as already demonstrated, since the HV control part 10 performs control for maintaining the charge amount of the battery 9 in the new target control range 62, the battery is charged before the hybrid vehicle arrives at the registration location. The charging amount of 9 increases and enters the new target control range 62.

  Subsequent to step 351, the process proceeds to step 353, where it is determined whether or not the hybrid vehicle has come out of a circle having a set distance centered on the registered location. If it is determined that it has come out, the process proceeds to step 359. If it is determined that it has not come out, the process proceeds to step 355.

  In step 355, the registration time A paired with the registration location is compared with the current time to determine whether or not the current time has passed the registration time A, and if it is determined that the time has passed, step 359 is continued. If it is determined that it has not passed, the process proceeds to step 357.

  In step 357, the current position calculated based on the signal from the position detector 11 is compared with the position of the registered place, and it is determined whether or not the hybrid vehicle has arrived at the registered place. The process proceeds to step 359, and if it is determined that it has not arrived, the process returns to step 353.

  In step 359, the target control range of the charge amount of the battery 9 is changed. Specifically, an upper limit SOC and lower limit SOC change command is output to the HV control unit 10. This change command includes an instruction to return to the upper limit SOC and the lower limit SOC before the last change.

  When such a change command for the upper limit SOC and the lower limit SOC is output to the HV control unit 10, the HV control unit 10 changes the current upper limit SOC and lower limit SOC to the upper limit SOC and lower limit SOC before the last change. (In other words, the upper limit SOC and the lower limit SOC of the initial value are restored). Thereby, the control range of the charge amount of the battery 9 returns to the range 61 before the change.

  In addition, since it is used when returning the upper limit SOC and the lower limit SOC, the HV control unit 10 stores the upper limit SOC and the lower limit SOC immediately before the change whenever the upper limit SOC and the lower limit SOC are changed. Yes.

  In this way, by returning the current upper limit SOC and lower limit SOC to the upper limit SOC and lower limit SOC before the last change, unnecessary increase of the battery 9 can be prevented.

  In the example of FIG. 9, if the registration time A is 7 am and the registration time B is 10 pm, the vehicle enters the circle 42 at 10:30 pm and then exits the circle 42. If it arrives at the registration location 31e within 10 minutes, the control range of the battery 9 is restored by exiting the loop of step 353 → 355 → 357 → 353 and proceeding to step 359. However, at this time, the charged amount of the battery 9 is already within the target control range 62 before returning to the original state.

  And the next morning, when the hybrid vehicle starts the pre-travel air conditioning operation (for example, warm-up operation), the charge amount of the battery 9 is higher than normal, so even if the charge amount of the battery 9 decreases due to the pre-travel air conditioning operation, The possibility of starting the engine 1 is low. When the hybrid vehicle starts traveling after the pre-travel air conditioning operation, the target control range has already been restored, so the battery 9 is not maintained at an unnecessarily high charge amount.

  In the example of FIG. 9, if the registration time A is 7:00 am and the registration time B is 10 pm, the vehicle enters the circle 42 at 6:30 am and then exits the circle 42. If it is past 7 am without arriving at the registration location 31e, the possibility that the air conditioning operation before traveling will be performed is low even if the hybrid vehicle subsequently arrives at the registration location 31e. Therefore, in such a case, the loop of step 353 → 355 → 357 → 353 is exited from step 355 and the process proceeds to step 359 to restore the target control range of the battery 9.

  In addition, in the example of FIG. 9, if the registration time A is 7:00 am and the registration time B is 10 pm, the vehicle must enter the registration place 31e after entering the circle 42 at 11:00 am If the player goes out of the circle 42 again at 11:10 pm, it is considered that he / she has just passed through the vicinity of the registration location 31e, not to the registration location 31e. Therefore, in such a case, the loop of step 353 → 355 → 357 → 353 is exited from step 353 and the process proceeds to step 359 to return the target control range of the battery 9 to the original.

  As described above, the charge amount control device 20 of the present embodiment records the registered place as the place where the pre-travel air-conditioning operation is performed in the learning process 200, and also before performing the pre-travel air-conditioning operation at the registered place. The time at which the hybrid vehicle is parked at the registration location is recorded as registration time B.

  Further, based on the fact that the hybrid vehicle has entered from outside the area within a predetermined set distance from the registered location, a control target time zone 46 including the registered time B is calculated, and the hybrid vehicle is determined from the registered location. It is determined whether or not the entry time that has entered from outside the area within the predetermined set distance is within the control target time zone 46 (320, 330, 340).

  When it is determined that the entry time is within the control target time zone 46, the control is performed so that the charge amount of the battery 9 is within a predetermined initial target control range 61 (corresponding to an example of the first range). From this state, control is performed so that the amount of charge of the battery falls within a target control range 62 (corresponding to an example of a second range) whose upper limit and lower limit are larger than the initial target control range 61.

  In this way, a place where there is a high possibility of performing the pre-travel air-conditioning operation is recorded as a registered place, and the time at which the vehicle is parked at the registered place before performing the pre-travel air-conditioning operation at the registered place is recorded as the registered time B. Then, when the hybrid vehicle approaches the registration location and the approach time is within a time zone including the registration time B, the charge amount control device performs air conditioning before traveling after the hybrid vehicle is parked at the registration location. It is predicted that the operation will be performed, and control is performed so that the charge amount of the battery for the motor falls within the second range in which the upper limit and the lower limit are larger than the first range.

  In this way, even if the air conditioning operation before traveling is performed next time at the registration location, the charge amount of the battery is larger than usual, so the engine is started at that time and the air conditioner is operated. The need to generate electrical energy for use is reduced.

  In addition, in the learning process 200, the control unit 24 records the time at which the pre-travel air conditioning operation is performed at the registration location as the registration time A, and the hybrid vehicle is out of the area within a predetermined set distance from the registration location. Based on having entered, a time zone starting from the time based on the registration time B and ending at the time based on the registration time A is calculated, and whether or not the entry time is within the calculated time zone Determine whether.

  In this way, the time at which the pre-travel air-conditioning operation is performed at the registration location is recorded as the registration time A, and the time zone starting from the time based on the registration time B and ending at the time based on the registration time A is defined as the entry time. It comes to compare.

  According to the inventor's study, even if the vehicle returns to the registration location at a time that is too much of the registration time B that is assumed to park the hybrid vehicle at the registration location before performing the pre-travel air conditioning operation at the registration location, If the time is around the registration time A where the pre-travel air-conditioning operation is supposed to start or before the registration time A, the possibility of performing the pre-travel air-conditioning operation at the departure is also high. Therefore, the charge amount can be controlled more efficiently by doing in this way.

  In addition, in the pre-travel air conditioning operation recording process 100, the control unit 24 sets the time when the pre-travel air conditioning operation is performed, the position of the hybrid vehicle at the time, and the IG off time immediately before performing the pre-travel air conditioning operation, respectively. The process of recording in the storage medium (23) as one pre-travel air-conditioning operation record as the pre-travel air-conditioning operation location, the pre-travel air-conditioning operation time, and the immediately preceding off time is repeatedly executed.

  In the learning process 200, a plurality of pre-travel air-conditioning operation records in which the pre-travel air-conditioning operation location and the pre-travel air-conditioning operation time are concentrated more than a predetermined standard are recorded based on the recorded records of the pre-travel air conditioning operation for a plurality of times. The representative position of the pre-travel air-conditioning operation place in the extracted plurality of pre-travel air-conditioning operation records is recorded as a registered place, and the time centered on the representative time of the immediately preceding off time in the extracted multiple pre-travel air-conditioning operation records The range is set, and the past boundary of the time range is recorded as the registration time B.

  Thus, based on the time when the actual air conditioning operation before traveling is performed, the position of the hybrid vehicle at the time, and the IG off time immediately before performing the air conditioning operation before traveling, the registration location and the registration time are statistically calculated. Since B is calculated, the driver does not have to input the location and time as the registration location and registration time B by himself / herself, and the convenience is increased accordingly.

  In the pre-travel air-conditioning operation recording process 100, the charge amount control device 20 keeps the hybrid vehicle stopped for a set time or longer after the IG is turned on in the pre-travel air-conditioning operation record process, and the hybrid vehicle air-conditioner operates. And the difference between the set temperature of the air conditioner and the outside air temperature outside the hybrid vehicle is equal to or greater than a reference value, The IG OFF time immediately before IG ON is recorded as one pre-travel air conditioning operation record as the pre-travel air conditioning operation location, the pre-travel air conditioning operation time, and the immediately prior OFF time, respectively.

  Thus, based on the time when the actual air conditioning operation before traveling is performed, the position of the hybrid vehicle at the time, and the IG off time immediately before performing the air conditioning operation before traveling, the registration location and the registration time are statistically calculated. Since B is calculated, the driver does not have to input the location and time as the registration location and registration time B by himself / herself, and the convenience is increased accordingly.

  Further, the control unit 24 calculates an expected arrival time of the hybrid vehicle to the registered location based on the fact that the hybrid vehicle enters from outside the area within a predetermined set distance from the registered location, A determination is made as to whether or not the entry time is within the time zone starting from the time required for the expected arrival time with respect to the registration time B as a starting point and ending with the registration time A as an end point. In this way, charging control can be performed with higher accuracy by calculating the start point of the time zone in consideration of the estimated time required for arrival at the registered location of the vehicle.

In the above embodiment, the control unit 24 is
By executing the learning process 200, it functions as an example of a learning unit, and by executing steps 320, 330, and 340 of the monitoring process 300, it functions as an example of a determination unit and by executing step 350 of the monitoring process 300. It functions as an example of control means.

(Other embodiments)
As mentioned above, although embodiment of this invention was described, the scope of the present invention is not limited only to the said embodiment, The various form which can implement | achieve the function of each invention specific matter of this invention is included. It is. For example, the following forms are also acceptable.

  In the above embodiment, the hybrid vehicle remains stopped for a set time after the IG is turned on, the air conditioner of the hybrid vehicle is operating, and the set temperature of the air conditioner and the outside air temperature outside the hybrid vehicle Based on the difference being equal to or greater than the reference value, it is determined that the pre-travel air conditioning operation is being performed, and the pre-travel air conditioning operation record is recorded. However, it may be determined that the pre-travel air conditioning operation is performed by another method.

In the above embodiment, the charge amount control device 20 automatically determines that the pre-travel air conditioning operation is being performed, and records the pre-travel air conditioning operation record. However, the pre-travel air conditioning operation record may be recorded by another method. For example, every time the pre-travel air-conditioning operation is performed, the driver manually operates the operation unit to input information on the pre-travel air-conditioning operation record, and the control unit 24 selects the pre-travel air-conditioning operation record based on the input information. It may be recorded.

  In the above embodiment, the charge amount control device 20 automatically creates and records the registration times A and B and the registration place for the pre-travel air conditioning operation based on the pre-travel air conditioning operation record. Yes. However, the registration times A and B and the registration location may be recorded by another method. For example, the driver manually operates the operation unit to input a registered place as a place where the pre-travel air conditioning operation is assumed to be performed, and the time when the driver is assumed to perform the pre-travel air conditioning operation at the registered location is registered time. As A, the time when the hybrid vehicle is parked at the registration location immediately before performing the pre-travel air conditioning operation at the registration location is input as the registration time B, and the control unit 24 inputs the registration time A, B. The registration location may be recorded.

  Moreover, in the said embodiment, the time slot | zone 46 which makes the starting point the time 44 which goes back by the estimated required arrival time 45 on the basis of the registration time B as a reference | standard, and uses the registration time A as the end point is employ | adopted as control object time. The control target time is not necessarily limited to this, and may be a time zone in which it is assumed that if the hybrid vehicle approaches the registration location within the control target time, the air conditioning operation before traveling will be performed later at the registration location. That's fine.

  For example, the end point of the control target time may be a time that is back from the registration time A by the expected arrival time. Further, for example, the end point of the control target time may be set one hour after the registration time B. That is, the start point may be the time around the registration time B based on the registration time B, and the start point may be the time around the registration time A based on the registration time A.

  The charge amount control device 20 has road map data, calculates a route from the current position to the destination based on the road map data, and uses the calculated route (using an image display device and a sound output device). It may be a navigation ECU for guiding.

  Moreover, in the said embodiment, although the detection signal of the outside temperature sensor 14 is directly output to the charge amount control apparatus 20, the detection signal of the outside temperature sensor 14 is output to the air conditioner ECU 12, and the air conditioner ECU 12 The detection signal may be output to the charge amount control device 20.

  In the above embodiment, each function realized by the control circuit 24 executing the program is realized by using hardware having those functions (for example, an FPGA capable of programming the circuit configuration). You may come to do.
