Description

  The present invention relates to an in-vehicle device control apparatus, and more specifically, in addition to charging an in-vehicle battery using an external power source, other in-vehicle electric devices can be operated using the power of the external power source. The present invention relates to a control device.

  An electric vehicle (EV) and some hybrid vehicles (HEV) that run by driving a driving motor using electric power in a high-voltage on-vehicle battery are connected to an on-board charger connected to an external power source. The cruising distance greatly depends on the remaining charge of the in-vehicle battery.

  In addition, since the exhaust heat and power of the internal combustion engine cannot be used at all times in an electric vehicle or the like, as in a vehicle that constantly operates the internal combustion engine, an electric heater or cooling system that uses the electric power in the in-vehicle battery is used. Equipped with an air conditioner to improve comfort in the passenger compartment. For this reason, especially in summer and winter when the air conditioner is used, the power consumption of the in-vehicle battery increases, and the cruising distance tends to be shortened.

  By the way, the reservation air-conditioning function (pre-air-conditioning function) that improves the comfort in the vehicle interior by operating the air-conditioning device before getting on the vehicle when the use start time is decided like commuting, etc. In-vehicle device control apparatus equipped with a) is put into practical use. However, when this reservation air conditioning function is used, the power in the charged in-vehicle battery is consumed by the air conditioner, and the cruising range is shortened.

  In order to eliminate this inconvenience, the in-vehicle device control device determines the maximum output current value that can be output from the charger based on the output voltage of the external power supply, and changes the current value distributed to the in-vehicle battery and air conditioner This is proposed in Patent Document 1.

Japanese Patent No. 3450906

However, in the in-vehicle device control apparatus as described in Patent Document 1, when the maximum output current value of the external power source is small, the amount of power supplied to the air conditioner is suppressed. In this case, the air conditioner cannot function sufficiently, and the passenger compartment cannot be prepared in a comfortable environment before boarding.
Then, this invention aims at providing the vehicle equipment control apparatus which can charge a vehicle-mounted battery, ensuring the operation | movement of the vehicle-mounted electrical equipment required for the preparation before boarding.

  A first aspect of the present invention is an in-vehicle device control apparatus that operates by supplying electric power to an in-vehicle battery of an in-vehicle device mounted on the vehicle and another in-vehicle electric device from an external power source installed outside the vehicle. A supply power detection unit that detects a power consumption amount of the external power supply and a power consumption acquisition unit that acquires a power consumption amount of the in-vehicle electric device, and the supply power detection unit detects The power amount supplied from the external power source to the in-vehicle battery and the in-vehicle electrical device is adjusted based on the power amount and the power consumption amount acquired by the power consumption acquisition unit, and the in-vehicle electrical device is given priority from the external power source. It is characterized by supplying power.

The first aspect of the present invention, when said supply power amount to be detected of the supply power detector exceeds the power consumption for obtaining the power consumption acquiring unit, the surplus from the external power source of the supply power amount The portion is supplied to the in-vehicle battery for charging .
Furthermore, the first aspect of the present invention, wherein when the supply power amount to be detected of the supply power detector is less than the power consumption amount for obtaining the power consumption acquiring unit stops the charging of the vehicle battery, The on-board electrical device is configured to supply power from the external power source with the amount of power supplied .

As a second aspect of the present invention, a remaining amount detection unit for detecting the remaining charge amount of the in-vehicle battery is provided, and the remaining charge amount detected by the remaining amount detection unit is equal to or greater than a preset limit value. Sometimes it is preferable to stop charging the in-vehicle battery.
As a 3rd aspect of this invention, it has the remaining amount detection part which detects the charge remaining amount of the said vehicle-mounted battery, and the charge remaining amount which the said remaining amount detection part detects is less than the preset limit value. Sometimes, it is preferable to stop the power supply to the in-vehicle electric device.

As a 4th aspect of this invention, the operation start part which starts operation | movement of the said vehicle-mounted electrical equipment at the preset time is provided, and it is preset before reaching the operation start setting time of the said vehicle-mounted electrical apparatus. It is preferable to start charging the in-vehicle battery from a certain time.
As a fifth aspect of the present invention, it is preferable to shut off the main relay when the charging of the in-vehicle battery is stopped.

  Thus, according to said 1st aspect, since electric power is preferentially supplied to an in-vehicle electric device according to the amount of electric power supplied from the external power source, the in-vehicle electric device is operated with priority over the charging of the in-vehicle battery. You can complete the preparations before boarding.

According to the first aspect, when the power supply amount of the external power source is less than or equal to the power consumption amount of the in-vehicle electrical device, the entire power supply amount of the external power source is supplied to the in-vehicle electrical device and operated. The vehicle-mounted electric device can be operated with priority over the charging of the vehicle-mounted battery.
According to said 1st aspect, when the power supply amount of an external power supply exceeds the power consumption amount of a vehicle-mounted electrical apparatus, a vehicle-mounted battery can be charged with the surplus of the power supply amount of the external power supply, It is possible to charge the on-vehicle battery while preparing before boarding.

According to said 2nd aspect, when the charge remaining amount of a vehicle-mounted battery is more than a setting limit value, since charge of a vehicle-mounted battery is stopped, consumption in a vehicle-mounted electrical device changes suddenly, and vehicle-mounted battery It is possible to avoid overcharging when the output power of the external power supply is supplied to the side, and to prevent the vehicle battery from being damaged in order to charge the vehicle battery while operating the vehicle electric device. it can.
According to the third aspect described above, when the remaining charge of the in-vehicle battery is less than the set limit value, the power supply to the in-vehicle electric device is stopped and the in-vehicle battery is charged. Despite the fact that the amount has dropped to the remaining charge level that needs to be charged, it is possible to avoid the timing when the vehicle-mounted electrical device is operated and the vehicle-mounted battery cannot be charged and the use starts. Thus, it is possible to reliably charge the in-vehicle battery with a small remaining charge.

According to the fourth aspect described above, the in- vehicle battery can be charged using the entire amount of power supplied from the external power supply before the in-vehicle electric device starts operating, and thereafter the in-vehicle electric device is The in-vehicle battery can be charged with the amount of power corresponding to the amount of power supplied while operating.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1-6 is a figure which shows the vehicle equipment control apparatus which concerns on 1st Embodiment of this invention.
(First embodiment)
In FIG. 1, a vehicle 100 is constructed by mounting a high voltage battery system 110, a traveling motor 120, an air conditioner (on-vehicle electric device) 150, a charging system 160, and an operation unit 170.

  The vehicle 100 is an electric vehicle (EV) that travels by rolling the driving wheel 130 by driving the traveling motor 120 using the electric power in the high voltage battery (vehicle battery) 111 of the high voltage battery system 110. Function. In the present embodiment, the case where the vehicle 100 is constructed as an electric vehicle will be described as an example. However, the present invention is not limited to this. The hybrid vehicle (HEV) includes an internal combustion engine as a driving source in addition to the traveling motor 120. It goes without saying that it may be applied to the above).

  Further, in the vehicle 100, an air conditioner 150 and a charging system 160 are connected to a high voltage line DH that electrically connects a high voltage battery 111 so that power can be supplied to the traveling motor 120. The air conditioner 150 performs cooling, heating, dehumidification, etc. of the passenger compartment using the electric power in the high voltage battery 111 according to various conditions set from the operation unit 170. Similarly, the charging system 160 is configured to charge the high-voltage battery 111 by receiving power supply from the external power source 200 according to various setting conditions.

  The high voltage battery system 110 connects the high voltage battery 111 to the high voltage line DH via the main relay 112. In the high voltage battery system 110, the battery controller 115 controls connection / disconnection of the main relay 112, thereby supplying the traveling motor 120 with the DC power stored in the high voltage battery 111.

  The traveling motor 120 is configured to rotate the drive shaft 121 by converting the DC power in the high-voltage battery 111 into three-phase AC power by the inverter 125 and supplying the three-phase AC power via the gear box 126. The driving wheel 130 is rolled by transmitting the rotational driving force of the driving shaft 121 to the axle 131.

  The air conditioner 150 includes a PCT (Positive Temperature Coefficient) heater 151, a compressor 152, and an A / C (Air Conditioning) controller 155, and is constructed so that “pre-air conditioning” described later can be performed. . The PCT heater 151 generates heat by supplying electric power in the high-voltage battery 111 and heats the conditioned air blown out by a fan (not shown) into the vehicle interior. The compressor 152 is driven by supplying electric power in the high-voltage battery 111 and cools the conditioned air with heat of vaporization generated by jetting (expanding) the refrigerant into an evaporator (not shown) after compressing the refrigerant. The A / C controller 155 adjusts the degree of air conditioning in the vehicle interior by individually operating the above-described fan, a damper (not shown), etc. together with the PCT heater 151 and the compressor 152.

  The charging system 160 includes a charging port 161, a charger 162, a charging relay 163, and a DC / DC converter 169, and is constructed so that “night charging” to be described later can be performed. The charging port 161 is prepared so that the charging plug 210 of the external power source 200 can be electrically connected. The charger 162 adjusts the power source power supplied via the charging port 161 to a DC power having a voltage that can charge the high voltage battery 111 and outputs it to the high voltage line DH. The charging relay 163 is connected to the external power source 200 side by a controller (not shown) built in the charger 162 or is controlled by the vehicle controller 180 according to an input operation in the operation unit 170 described later, thereby allowing the charging port Connection / disconnection between 161 (external power source 200) and charger 162 is executed. The DC / DC converter 169 receives high-voltage DC power from the high-voltage battery 111 or the charger 162 via the high-voltage line DH, converts it to low-voltage DC power, and outputs it to the 12V battery 119.

The operation unit 170 includes an input unit 171, a display panel 172, and an operation controller 173. The input unit 171 is operated by an occupant of the vehicle 100 to input various conditions. The display panel 172 displays input conditions for the input unit 171 and the like. The operation controller 173 stores and holds various information necessary in a memory (not shown) in accordance with an input operation from the input unit 171 and causes the display panel 172 to display and output the input operation status.
In the operation unit 170, the operation controller 173 executes display processing for selecting and inputting from the input unit 171 so that control processing such as “pre-air conditioning” of the air conditioner 150 and “night charging” of the charging system 160 is performed at the set time. Various parameters necessary for control processing such as “pre-air conditioning” and “night charging” are set in the memory of the vehicle controller 180. As will be described later, the vehicle controller 180 appropriately executes a control process preset in the memory.

The high-voltage battery system 110 to the operation unit 170 of each part of the vehicle are controlled by the vehicle controller 180, and the vehicle controller 180 constitutes an operation start unit.
The vehicle controller 180 includes a battery controller 115 of the high voltage battery system 110, an inverter 125 of the traveling motor 120, an A / C controller 155 of the air conditioner 150, a charger 162 and a DC / DC converter 169 of the charging system 160, and an operation unit. It is connected to an operation controller 173 of 170 via a CAN (Controller Area Network) communication line DC and exchanges various signals with each other. Each of the units 115, 125, 155, 162, 169, 173, 180 for exchanging various signals is constructed by mounting a computer unit in which a CPU, a memory, and the like are modularized, and the CPU stores in advance in the memory. In accordance with the control program to be executed, the function is made based on the stored information in the memory and various received signals.

  In particular, the vehicle controller 180 responds to information stored in the memory and signals received from the battery controller 115, the A / C controller 155, and the charger 162 according to the charge air conditioning control program stored in advance in the memory by the CPU. By returning a control signal, the operation of the air conditioner 150 and the operation of the charger 162 are controlled. That is, the vehicle controller 180 constitutes an in-vehicle device control device.

Specifically, as shown in FIG. 2, the vehicle controller 180 receives various request signals including start / stop of the system input by operating the input unit 171 from the operation controller 173 of the operation unit 170. Various control processes are executed, and various conditions input by operating the input unit 171 are received and stored (set) in the memory.
Further, the vehicle controller 180 receives a remaining charge SOC (state of charge) in the high voltage battery 111 from the battery controller 115 of the high voltage battery system 110 and executes various control processes using the stored power. That is, the battery controller 115 constitutes a remaining amount detection unit. The battery controller 115 has a configuration for detecting the remaining charge SOC in the high voltage battery 111 based on detection information of a sensor for detecting the charge / discharge current value of the high voltage battery 111, and functions as a remaining amount detection unit. To do.

For example, in the normal control process, the vehicle controller 180 supplies a charging power value (supplied power) sent from the external power source 200 via the charger 162 when the charging plug 210 is connected to the charging port 161 of the charging system 160. Quantity). Vehicle controller 180 also sends to charger 162 an instruction for the maximum charging power value to be supplied to external power supply 200. Then, the vehicle controller 180 executes various control processes for receiving the remaining charge SOC in the high voltage battery 111 from the battery controller 115 and charging the high voltage battery 111. That is, the charger 162 constitutes a supply power detection unit.
Here, the charging power maximum value of the power source power sent to the external power source 200 and instructed is limited from the vehicle controller 180 side (high voltage battery 111 side) by setting it to a value larger than the charging power value received from the external power source 200. Without receiving the full power of the external power supply 200, the charging process can be performed. Note that charging to the 12V battery 119 may be performed by supplying necessary power from the high-voltage battery 111 or the charger 162 via the DC / DC converter 169 when charging during running is insufficient.

Further, in the normal control process, the vehicle controller 180 receives the request for operating the air conditioner 150 and executing the air conditioning process in the vehicle interior, and the maximum output air conditioning power consumption sent from the A / C controller 155. Receives the value (power consumption). Further, the vehicle controller 180 sends the A / C controller 155 to specify the air conditioning power consumption limit value for operating the air conditioner 150 and activates the air conditioner 150 with the power in the high voltage battery 111 to set the vehicle interior. Execute the air conditioning control process to make the temperature. That is, the A / C controller 155 constitutes a power consumption acquisition unit.
Here, the air conditioning power consumption limit value that is sent to the air conditioner 150 (A / C controller 155) and specified is set to a value larger than the air conditioning power consumption value received from the air conditioner 150, whereby the vehicle controller 180 side (high voltage battery). 111 side), air conditioning processing that consumes the full capacity of the air conditioner 150 can be performed.

At this time, as shown in FIG. 3, the vehicle controller 180 has a case where the remaining charge SOC (%) in the high-voltage battery 111 has reached a preset full charge determination value C1 (%). In this case, zero (W) is sent to the charger 162 as the charging power maximum value of the power source power of the external power source 200. That is, when the remaining charge SOC in the high voltage battery 111 is equal to or higher than the full charge determination value C1, the vehicle controller 180 stops the charging process to the high voltage battery 111 and the external power source 200 of the air conditioner 150 Allow operation with power supply.
At this time, if the remaining charge SOC is lower than the predetermined limit value C2 (%) that needs to be charged, the vehicle controller 180 air-conditions the air conditioner 150 (A / C controller 155). Zero (W) is sent as the power consumption limit value. That is, when the remaining charge SOC is less than the charge requirement determination value C2, the vehicle controller 180 stops the operation of the air conditioner 150 and charges the high voltage battery 111 with the power of the external power source 200. .

  Then, when “night charge” for charging the high voltage battery 111 with inexpensive midnight power is set from the operation controller 173 of the operation unit 170, the vehicle controller 180 sets a preset charge start time. During the elapsed time period, the night charge control process for charging the high voltage battery 111 with the power of the external power source 200 is executed. Here, in this embodiment, a case where a night time zone is set as the charging time will be described as an example. However, the present invention is not limited to this, and needless to say, it may be arbitrarily set according to a vehicle non-use time zone. Yes.

  At this time, when the vehicle controller 180 sets a so-called “pre-air-conditioning (reserved air-conditioning)” in which the vehicle interior is kept in a comfortable environment at the boarding time preset from the operation controller 173 of the operation unit 170. The air-conditioning control processing for starting the air-conditioning device 150 with the stored power in the high-voltage battery 111 or the power source power of the external power source 200 to bring the passenger compartment to a set temperature is executed at the preset pre-air-conditioning start time. . Here, in the present embodiment, a case where the passenger compartment is comfortably air-conditioned before the commuting time will be described as an example, but the present invention is not limited to this, and it is needless to say that it may be arbitrarily set according to the use start time of the vehicle. .

  Further, at this time, when the vehicle controller 180 executes “pre-air conditioning” and “night charging” at the same time, the external power source 200 adds the air-conditioning power consumption value (power consumption amount) of the air-conditioning device 150 to the high-voltage battery 111. When power cannot be supplied with a charging power value sufficient for charging, power distribution is adjusted to give priority to “pre-air conditioning” over “night charging”.

  For example, when the charging power value of the external power source 200 is less than the air conditioning power consumption value of the air conditioner 150, the vehicle controller 180 ensures the operation of only the air conditioner 150. At this time, since there is no surplus power for charging the high voltage battery 111 due to the operation of the air conditioner 150, the charging of the high voltage battery 111 is stopped. In addition, when the charging power value of the external power source 200 exceeds the air conditioning power consumption value of the air conditioner 150, the vehicle controller 180 secures operation by supplying the air conditioning power consumption value to the air conditioning apparatus 150, Charging is performed to supply the high voltage battery 111 with a surplus with respect to the air conditioning power consumption value of the air conditioner 150 in the charging power value of the external power source 200.

  Specifically, as shown in the flowchart of FIG. 4, the vehicle controller 180 is activated when the ignition is turned on (step S <b> 11), and then checks whether there are various setting requests stored in the memory from the operation unit 170. Confirm (step S12). When “night charging” and “pre-air conditioning” are confirmed in the various setting requests (step S13), the standby state of the air conditioning control during charging is maintained, for example, at midnight when the electricity rate is low (for example, Check whether or not the pre-air conditioning start time has been reached by subtracting the time required for air conditioning in the passenger compartment (for example, 15 minutes) from the commuting time (for example, 7:00 am) in the time zone from midnight to 7:00 am (Step S14).

In step S14, when it is confirmed that the pre-air conditioning start time in the midnight time has been reached, it is confirmed whether or not the charging plug 210 of the external power source 200 is connected to the charging port 161 of the charging system 160. (Step S15) If it is not connected, the control process is terminated. If the connection of the charging plug 210 to the charging port 161 is confirmed in step S15, the charging system 160 and the air conditioner 150 are activated (step S16), and the high voltage generated by the charger 162 and the external power supply 200 is activated. The air conditioning control process by the air conditioner 150 is started together with the charging control process for the battery 111 (step S17).

  Thereafter, it is confirmed whether or not the commuting use start time set as the “pre-air conditioning” is reached (step S18), and the charging process and the air conditioning process are continued until the commuting time is reached. In this case, the charging control process is stopped and the air conditioning control process is also temporarily stopped (step S19). Subsequently, a stop process of the charging system 160 and the air conditioner 150 is performed, and a grounding process is performed so that the charging plug 210 of the external power source 200 can be safely detached from the charging port 161 of the charging system 160. This control process is terminated (step S20).

At this time, when starting the air conditioner 150 in step S17, the vehicle controller 180 first starts in the high voltage battery 111 as shown in the flowchart of FIG. It is confirmed whether or not the remaining charge SOC is less than the full charge determination value C1 (step S171). If the remaining charge SOC is equal to or greater than the full charge determination value C1, the power supply of the external power supply 200 is supplied only to the air conditioner 150 to operate without power limitation (step S172). Specifically, zero (W) is sent to the charger 162 as the charging power maximum value of the power supply power, and the charging control itself stops (stops), and the A / C controller 155 corresponds to the maximum output air conditioning power consumption value. The air conditioning power consumption limit value Pa (W) is sent. At this time, the charger 162 inhibits the charging of the high voltage battery 111 by sending a signal for limiting the charging to the battery controller 115 and shutting off the main relay 112.
Thereby, it can avoid that the high voltage battery 111 will be further charged from the state charged more than full charge determination value C1, and will be in an overcharge state. For example, the consumption of in-vehicle electrical equipment such as the air conditioner 150 suddenly changes and the amount of charge to the high voltage battery 111 increases momentarily, which causes the high voltage battery 111 to be overcharged and damaged. Can be prevented in advance.

In step S171, when the remaining charge SOC is less than the full charge determination value C1, the vehicle controller 180 continues to determine whether the remaining charge SOC in the high voltage battery 111 is less than the determination required value C2. (Step S173). If the remaining charge SOC is less than the charge determination value C2, only the high voltage battery 111 is supplied with power from the external power source 200 and charged (step S174). More specifically, zero (W) is sent as the maximum output air conditioning power consumption value to the A / C controller 155 to stop the air conditioning control, and the charger 162 is charged as the maximum charge power value of the external power supply 200. A charging power value Pc (W) corresponding to the capability is sent.
As a result, it is possible to prevent the air conditioning of the passenger compartment from starting even though the high voltage battery 111 needs to be preferentially charged in a state of less than the charge requirement determination value C2, When traveling, it can be avoided that the amount of charge of the high-voltage battery 111 is insufficient at an early stage.

In step S173, if the remaining charge SOC is less than the full charge determination value C1 and equal to or greater than the charge necessity determination value C2, the vehicle controller 180 charges the high voltage battery 111 with the activation of the air conditioner 150. However, the power supply that gives priority to the operation of the air conditioner 150 over the charging of the high voltage battery 111 is performed (step S175).
In this step S175, when the vehicle controller 180 starts up the air conditioner 150 together with charging of the high voltage battery 111, the air conditioning consumption of the air conditioner 150 is determined from the charged power value of the external power source 200 as shown in the flowchart of FIG. An arithmetic process for subtracting the power value is performed (step S271).

  It is confirmed whether or not the calculation result (difference) in step S271 is zero or negative (step S272). If the calculation result is zero or negative, the power supply power of the external power source 200 is supplied only to the air conditioner 150. To operate without power limitation (step S273). More specifically, zero (W) is sent to the charger 162 as the maximum charging power value to stop the charging control itself, and the A / C controller 155 uses the entire amount of supplied power to the air conditioning power consumption limit value Pa ( W) is sent to operate the air conditioner 150. At this time, the charger 162 inhibits the charging of the high voltage battery 111 by sending a signal for limiting the charging to the battery controller 115 and shutting off the main relay 112.

  If the calculation result (difference) in step S271 does not become zero or negative, the air conditioner 150 is preferentially operated and the high voltage battery 111 is charged with a surplus (step S274). Specifically, the air conditioning power consumption limit value Pa (W) is sent to the A / C controller 155 to operate the air conditioner 150 without power limitation, and the difference power value Pc (W) of the calculation result that is the surplus is sent. Control is sent to the charger 162 to charge the high voltage battery 111.

  As a result, while the air conditioner 150 is sufficiently operated to perform the air conditioning process in the vehicle interior, the charging process to the high voltage battery 111 can also be performed in excess, and the amount of power necessary for traveling Can be charged into the high voltage battery 111 and the passenger compartment can be made comfortable when riding. In addition, when there is no surplus to charge the high voltage battery 111, only the air conditioner 150 can be operated to make the passenger compartment a comfortable environment when boarding.

  Thus, the vehicle controller 180 sets “night charge” and “pre-air conditioning” when the received remaining charge SOC is in a charge state between the full charge determination value C1 and the charge necessity determination value C2 or more. In the case of (requested), the surplus power is supplied at the same time that the air conditioner 150 is preferentially operated at the required air conditioning power consumption limit value Pa by receiving the supply of electric power with full capacity from the external power source 200. The high voltage battery 111 can be charged with the amount of electric power.

FIG. 7 shows the state of charge of the high voltage battery 111 from the pre-air conditioning start time. A broken line (1) indicates a case where the power supply power of the external power supply 200 is particularly larger than a necessary air conditioning power consumption of the air conditioner 150, and a solid line (2) indicates that the power supply power of the external power supply 200 is a required air conditioning power consumption of the air conditioning apparatus 150. The broken line (3) shows the case where the power source power of the external power source 200 is equal to the required air conditioning power consumption of the air conditioner 150. In the case of the broken line (1), the high voltage battery 111 is charged while operating the air conditioner 150. When the remaining charge SOC reaches the full charge determination value C1, the charging of the high voltage battery 111 is stopped and the air conditioner 150 Continue operation until the scheduled departure time. In the case of the solid line (2), the high voltage battery 111 is charged while operating the air conditioner 150 until the scheduled departure time. In the case of the broken line (3), the high voltage battery 111 is not charged, but the air conditioner 150 is operated until the scheduled departure time.
Therefore, as shown in FIG. 7, the air conditioner 150 is driven with sufficient power from the pre-air-conditioning start time to execute a control process for comfortably air-conditioning the passenger compartment, and at the same time, the high-voltage until the commuting use start time. The battery 111 can also be charged, and at the commuting time, the high-voltage battery 111 can be replenished with electric power necessary for traveling to make the vehicle interior comfortable. That is, when the power supply capability of the external power source 200 is insufficient, the high voltage battery 111 can be charged with a surplus while operating the air conditioner 150 with sufficient power.

(Second Embodiment)
FIG. 8 is a diagram showing an in-vehicle device control apparatus according to the second embodiment of the present invention. Here, since the present embodiment is configured in substantially the same manner as the first embodiment described above, the same reference numerals are given to the same configurations using the drawings, and the characteristic portions will be described.
Similarly to the first embodiment, the vehicle 100 of the present embodiment is constructed by mounting the high-voltage battery system 110, the traveling motor 120, the air conditioner 150, the charging system 160, and the operation unit 170 on the vehicle. In the above embodiment, an example in which “night charging” and “pre-air conditioning” are started simultaneously at the pre-air conditioning start time will be described. In this embodiment, “night charging” and “pre-air conditioning” are separately performed. Built to run on.

Specifically, as shown in FIG. 8, the vehicle controller 180 is connected to the charging system 160 after a preset charging start time (for example, midnight) in a midnight time zone when the electricity rate is low. When the connection of the charging plug 210 of the external power source 200 to the charging port 161 is confirmed, the charger 162 and the external power source 200 are activated to start the charging control process for the high voltage battery 111. When the vehicle controller 180 confirms that the pre-air conditioning start time (for example, 6:45 in the morning), which is obtained by subtracting the time required for air conditioning in the vehicle interior from the preset commuting time, the air conditioner 150 starts the air conditioning control process.

  At this time, the vehicle controller 180 receives from the battery controller 115 that, for example, after starting charging at midnight, the battery controller 115 has reached a fully charged state in which the remaining charge SOC in the high voltage battery 111 has reached the full charge determination value C1. The charging control is stopped and the power supply from the external power source 200 is stopped. After the stop of the charge control, the high voltage battery 111 is stable at the remaining charge SOC of the full charge determination value C1.

  Further, for example, after starting pre-air-conditioning at 6:45 am, the vehicle controller 180 comfortably air-conditions the interior of the vehicle and temporarily stops air-conditioning control when the commuting time comes. At this time, the power supplied from the external power source 200 is not supplied to the high voltage battery 111 but is supplied to the air conditioner 150 and consumed, and the high voltage battery 111 is overcharged. Therefore, it is possible to complete the air conditioning that makes the passenger compartment a comfortable environment at the time of commuting when traveling while maintaining a fully charged state.

Accordingly, the air conditioner 150 can be driven with sufficient power from the pre-air conditioning start time to comfortably air-condition the passenger compartment by the commuting use start time, and to the high voltage battery 111 by the pre-air conditioning start time. Can be completed by running the charge.
Here, in this embodiment, the case where “night charging” and “pre-air conditioning” are completed separately will be described as an example. However, when “pre-air conditioning” is started before “night charging” is completed. In the same manner as in the above-described embodiment, at the timing of performing “night charging” and “pre-air conditioning” in parallel, “pre-air conditioning” is preferentially processed and “night charging” is performed with surplus power.

  While embodiments of the invention have been disclosed, it will be apparent to those skilled in the art that changes may be made without departing from the scope of the invention. All such modifications and equivalents are intended to be included in the following claims.
