Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is equipped with an automobile telephone, and on a road or the like in which a traveling motor is driven by an on-vehicle battery (hereinafter, also simply referred to as a battery) having a nominal voltage of 240V or the like. The present invention relates to a telephone control system for an electric vehicle, which is suitable for application to an electric vehicle that travels on a road.

[0002]

2. Description of the Related Art Recently, there has been proposed an electric vehicle configured to supply power from a battery to a motor inverter and drive the traveling motor by the motor inverter.

In such an electric vehicle, the battery is charged by using an external power source while the vehicle is parked.

When charging is performed by an AC power supply at home or business, for example, as an external power source, charging is performed at each parking lot, but when the driver (user) performs an operation for charging or the charging state. When I checked, I had to go to the parking lot each time. In addition, it takes a maximum of about 8 to 12 hours to fully charge the battery. Therefore, it is extremely troublesome to check the charging state during this time.

In addition, since the capacity of a battery that can be installed in an electric vehicle, that is, the battery capacity is limited, a power source for charging is currently installed in a shopping center or a public parking lot in order to extend the mileage. Consideration to establish it is also in progress.

Under such circumstances, it is expected that the electric vehicle will be charged frequently and for a long time when the vehicle is parked at home, in the office, or on the road.

An electric vehicle differs from a general gasoline vehicle in that an air conditioner also uses an electric compressor (hereinafter, an air conditioner using an electric compressor is referred to as an electric air conditioner. The electric air conditioner is also simply referred to as an air conditioner. Since it can be operated independently of the traveling motor, it can be operated by using not only the electric power of the battery of the own vehicle but also the electric power of the external power source.

Therefore, during parking, it is possible to comfortably air-condition the vehicle interior by operating the electric air conditioner at the same time as charging by an external power source or independently.

From this point of view, the vehicle air conditioner is operated by the vehicle-mounted timer while the electric vehicle is being charged, and the cool-down during cooling and the heat during heating are preliminarily set at the boarding time without reducing the capacity of the battery. A pre-air conditioning (hereinafter referred to as "pre-air conditioner") system that can be upgraded is proposed (Japanese Patent Laid-Open No. 5-15)
No. 5233).

During operation of the above-mentioned pre-air-conditioning system, the vehicle is separated from the vehicle by a radio wave transmission / reception device dedicated to the vehicle and having a liquid crystal display, a so-called remote control key, in other words, a remote control device. A device in which the charging state by the charger is displayed on the liquid crystal display at the position is also conceivable (Japanese Patent Application No. 6-92562).
See the specification).

[0011]

However, in the above-mentioned prior art, since the remote control key is exclusively used for the vehicle, the remote control key is always carried in order to execute the pre-air conditioning function. There was the inconvenience of having to do it.

Also, with this remote control key, the wireless output is limited because it is direct communication between the transceiver installed in the vehicle and the transceiver built in the remote control key, and the remote control while the vehicle is visible is limited. There is an inconvenience that it cannot be used in a place where the communication environment is not good, such as a position far from the vehicle, a building, etc., because the control is limited.

The present invention has been made in view of the above problems, and manages (confirms and controls) the charging state and / or the air conditioning state, etc. even in a position far away from a vehicle, in a building, etc. It is an object of the present invention to provide a telephone control system for an electric vehicle, which is capable of including the above.

In the present invention, basically, the function of the control panel 50 and the function of the remote controller key 45 for controlling the electric air conditioner 31 are controlled by an external telephone connected to a general public line network (for example, at home). It is intended to achieve this by using a telephone or public telephone) 76 or a commercially available mobile telephone 75.

Therefore, in this embodiment, a car telephone 70 is arranged in the electric car 11. The car telephone 70 includes a telephone controller 28 connected to the charging controller 15, the air conditioner controller 21, and the like, a telephone 71, a wireless device 72, and an antenna 73, which are wirelessly connected to the telephone controller 28 in the vehicle, for example, wirelessly. Composed of. Then, the data from the telephone controller 28 is radiated as a radio wave through a modem (not shown), the wireless device 72 and the antenna 73, and this radio wave is transmitted to the mobile telephone 75 through the repeater 74, and also the telephone through the public line network. Sent to 76. Here, the repeater 74 is conceptually shown as one constituent element including a wireless base station, a wireless line control station, a car telephone exchange station, a public line network exchange station, and the like.

As is well known, the portable telephone 75 has key switches (push-buttons) such as numeric keys "0" to "9", "*" and "#" symbol keys, and "function" keys. A switch) and an LCD 77 or the like serving as display means are arranged.

Next, the operation of the above embodiment will be described with reference to the flowchart relating to the telephone controller 28. In this case, the operation using the mobile phone 75 will be described, and the operation using the external telephone 76 will be omitted since it is substantially the same except that the external telephone 76 is not equipped with a liquid crystal display. Further, the control based on the flowchart described below is basically that the electric vehicle 11 is parked, no one is in the electric vehicle 11, and the AC power source is connected through the plug 26. , Or the charger 62 is connected through the connector 60, and the contactor 24 is in a state of being connected to the desired side.

FIG. 3 is a flow chart showing the whole process. First, the whole operation will be briefly explained.

First, the telephone controller 28 is in a standby state (standby mode) for monitoring the states of the charging controller 15, the motor controller 27 and the air conditioner controller 21. Then, based on a predetermined control program, when trying to convey some information (such as information on abnormal charging determination as described in detail later) to the user of the mobile phone 75, the car telephone 70 is configured. The telephone number of the mobile telephone 75 is automatically dialed through the telephone 71 and the wireless device 72, and a call signal is automatically transmitted, so-called automatic transmission is performed. If there is no automatic transmission item, the mobile phone 75 waits for the encrypted input from the mobile phone 75 and proceeds to the next step (step S1).

A driver (a driver, who is an electric vehicle who is a driver who wants to operate the electric air conditioner 31 before the boarding time by a pre-air conditioner function, at a position physically separated from the position of the electric vehicle 11 being parked. 11 users)
Is a personal identification number (encryption), for example, an identification number, that is,
A so-called ID number is input (step S2). In addition,
This cipher input may be input by a tone signal using a key switch on the mobile phone 75 or may be voice input by the user himself. In the case of voice input, the user's voice recognition device and voice discrimination device may be incorporated in the telephone controller 28 in advance. A voice synthesizing device is incorporated in the telephone controller 28 so that a predetermined voice message can be sent from the telephone controller 28 side to the mobile phone 75 side.

When the code entered in step S2 is correct, the charging state of the battery 12 by the charger 25 or the charger 62 from the telephone controller 28, the current operating state of the electric air conditioner 31, that is, the air conditioner state (described later). .) Is displayed on the LCD 77 which is the display means of the mobile phone 75 (step S).
3). This display can also be replaced with a voice message. In the following description, transmission of information from the mobile phone 70 to the mobile phone 75 is performed by a voice message and / or a display on the LCD 77, while the information from the mobile phone 75 to the mobile phone 70 is transmitted unless otherwise specified. The transmission shall be done by a voice message and / or a tone signal by the input of a key switch.

Next, a command such as an instruction to start the pre-air conditioner function is input from the mobile phone 75 (step S4).

Next, the telephone controller 28 determines the content of this command input (step S5).

In the case of control of the air conditioner, control of the air conditioner based on the contents of the input, for example,
Immediately operate the electric air conditioner 31 with the pre-conditioner,
Alternatively, control such as operation with a timer pre-air conditioner is performed (step S6).

If the control is related to charging in step S5, control such as start / stop of charging by the charger 25 and the charger 62 is performed based on the input contents (step S7).

Further, if it is determined in step S5 that the operation mode based on the command input is related to acquisition of information (for example, acquisition of temperature information in the compartment of the electric vehicle 11), the process returns to step S3. .

At the time when the air conditioning control in step S6 or the charging control in step S7 is completed, the telephone controller 28 monitors whether or not the mobile telephone 75 is on-hook.
Return to step S4 to wait for the input of the next command, while
If on-hook, the control is terminated (step S8).

Next, in the overall flow chart of FIG.
Detailed operation of the standby state of step S1 will be described with reference to the flowchart of FIG.

First, initial setting (switch, contactor setting, initial value setting of routine, etc., not shown), transmission destination telephone number setting and automatic transmission item setting are performed (step S1 (1)). In this case, the telephone number of the mobile phone 75 is set in the RAM in the telephone controller 28 as the destination telephone number. Further, in this standby state, the automatic transmission item sets three items of charging completion, charging abnormality and mischief detection. Therefore, the control programs related to these are stored in the ROM of the telephone controller 28, and the related control programs are also stored in the ROMs of the other charging controller 15, the air conditioner controller 21, and the motor controller 27.

Next, the charge controller 15 makes a charge abnormality detection determination including a mischief detection determination (step S1).
(2)) and whether the end of charging is detected (step S1 (3)) are continuously performed. The order of these determinations is arbitrary.

FIG. 5 shows a list of automatic transmission item flags related to these judgments.

FIG. 6 shows charging abnormality determination (step S1).
The detailed contents of (2)) are shown.

In FIG. 6, first, the charge controller 1
In order to confirm whether or not an abnormality of the charging system has occurred according to 5, the confirmation of the charging system is performed (step S1 (2-1)). Then, based on the confirmation result of the charging system, it is confirmed whether or not an abnormality has occurred in the charging system (step S1 (2-2)).

That is, in the system check in step S1 (2-1), as shown in FIG. 5, the charger 25 itself or the charging stand 61 itself is out of order, the voltage sensor 14 and the current sensor 13 are abnormal, and the contactor 24.
Etc., a voltage abnormality of the battery 12, an abnormality in which the hydrogen gas concentration of the battery 12 is high, etc. are set, the charge abnormality flag is set to "1" (step S1 (2-
3)), if it is normal, it remains "0", that is, it is reset. Note that these flags are provided in the charging controller 15, and the contents thereof are transferred to the telephone controller 28 and stored in the RAM.

After the system abnormality is detected, the power supply voltage is detected (step S1 (2-4)). Then, based on the detection result of the power source voltage, it is determined whether or not the AC power source is connected to the charger 25 or the charger 62 (step S1 (2-5)). Whether or not this AC power source is connected is determined in step S1 (2-
4) the detection result of the power supply voltage indicating whether the AC power is supplied between the input terminals of the charger 25, the charger 62
The determination can be made based on the detection result of the power supply voltage indicating whether or not a predetermined voltage is generated at the output side connector 60, and further, whether the plug 26 or the like is disconnected or a power failure has occurred can be determined, for example. , A micro switch or the like is embedded in the plug 26, and the plug 26 has an outlet 29.
It suffices to configure the micro switch to be in the closed state only when the micro switch is inserted into the battery, and to monitor the opening and closing of the micro switch by the charge controller 15.

In this way, when the power supply voltage on the input side of the charger 25 becomes zero volts, if the micro switch is in the closed state, there is a power failure, and if the micro switch is in the open state, the plug 26 is removed. Can be determined.

Also in connection with the charger 62, the charger 6
Whether the AC power supplied to 2 is a power failure, the connector 6
It can be determined whether 0 is off or not by measuring the impedance at the contact 60e point in the connector 60. Connector 6 when impedance is close to zero
0 is connected, and when the impedance is infinite, the connector 60 is disconnected. If the output voltage of the charger 62 becomes zero volts when the impedance is close to zero value, it is determined that there is a power failure, and if the impedance becomes infinite when the output voltage of the charger 62 becomes zero volts. It can be determined that the connector 60 is disconnected.

If it is detected in step S1 (2-5) that the plug 26 or the connector 60 is disconnected, that is, if the determination in step S1 (2-5) is not established, the battery 12 It is determined whether or not the current flowing out from the so-called carry-out current is larger than a predetermined current (step S1 (2-6)). If it is larger than the predetermined current, the vehicle is parked and the plug 2
6. Despite the disconnection of the connector 60, a relatively large current is consumed, so it is determined that someone is mischievous with the electric vehicle 11 such as the start of the traveling motor 38. And set the mischief flag to "1". on the other hand,
If the current is smaller than the predetermined current, the power supply connection flag simply indicating that the power supply connection has been disconnected is set to "1". Since the power supply connection flag can be distinguished from each other as described above, the power supply connection flag is managed separately as the plug / connector connection flag and the power failure flag.

FIG. 7 shows the detailed contents of the charge end determination (step S1 (3)) in the standby mode flowchart.

First, two-stage constant current charging of a lead battery will be described as an example. It is confirmed whether or not the control of the charger 25 by the charge controller 15 is in the second stage charge control state (step S1 (3-1)). The second-stage charge control state means that when the battery 12 is charged, the battery 12
Control of the charge controller 15 such that charging is performed with a relatively large first-stage charging current value until the capacity of 80% becomes about 80%, and thereafter, full charge is performed with a relatively small current value. Of these, the state of charge with a relatively small current value.

In consideration of the minimum operating current value specification of the electric air conditioner 31, the pre-air conditioner function is normally operable when the second-stage charging state is reached, and the margins of the chargers 25 and 62 are sufficient. It is possible to supply the output current that is to the electric air conditioner 31. In the first-stage charging state, almost all of the output currents of the chargers 25 and 62, in particular, the vehicle-mounted charger 25 are used for charging the battery 12, and the operating minimum current value of the electric air conditioner 31 (the above-mentioned minimum operating current) is used. In general, the electric current value corresponding to the value use cannot be secured, and the electric air conditioner 31 cannot be operated.

If the determination in step S1 (3-1) is not established, that is, if the second-stage charging control state is not established, it is determined that the first-stage charging control state is in effect and charging has not ended. Then, the process proceeds to step S1 (4) in the flow of the standby mode.

On the other hand, if it is determined in step S1 (3-1) that the second-stage charge control state is set, it is determined whether or not the voltage of the battery 12 becomes equal to or higher than the set voltage (step S1). (3-2)). At this time,
You may detect also the ratio of the time change of a battery voltage. This is because at the end of the second-stage charging, the rate of temporal change in the battery voltage has a characteristic of becoming steeper than in the previous state. Further, as the set voltage, an appropriate value that differs depending on the battery temperature is selected. This is because the battery voltage value in the fully charged state changes depending on the battery temperature.

When the determination in step S1 (3-2) is established, the charging end flag indicating that charging is completed is set (set to "1") and the flow returns to the standby mode (step S1 (3-)). 4)). When the charging is also controlled by the timer of the charging controller 15, even if the determination in step S1 (3-2) is not established, the charging is completed when the predetermined time has elapsed. As a matter of course (the determination in step S1 (3-3) is established), similarly, the charging end flag is set (step S1 (3-4)), and the process returns to the flow of the standby mode and before the time has elapsed (step S1 ( If the determination in 3-3) is not established), the flow returns to the standby mode without setting the charging end flag.

In the flow of the standby mode in FIG. 4, when the charging abnormality determination (including step S1 (2) and mischief determination) and the charging end determination (step S1 (3)) are completed, the automatic transmission item is set. It is determined whether it has occurred (step S1 (4)). In this case, the telephone controller 28 confirms whether or not there is a flag set in the automatic transmission item flag shown in FIG.

If the flag is set, the message corresponding to the set flag is selected from the ROM of the telephone controller 28 (step S1).
(6)).

The content of this message is, in this embodiment, "Abnormality has occurred in the charger or the like (in the charging system, depending on the content of the detected abnormality, for example, the voltage sensor or switch is changed). . "," The power supply was disconnected because the plug was unplugged, etc. "," The power supply was disconnected due to a power outage. "," Mischief occurred. ", And" Charging ends. " I did. " As described above, the message may be voice, and the mobile phone 7
5 may be displayed on the LCD 77. These can be determined in advance and can be changed on the way. In addition, although it is limited to a voice message to the telephone 76 under the present circumstances, it is needless to say that the message may be displayed when the telephone 76 also employs an indicator. When a facsimile is connected to the telephone set 76, the user may be notified by facsimile. Further, in the future, when the telephone set 76 is connected to the television, it may be displayed on the screen of the television together with the voice. This is convenient, for example, when charging outdoors in a place other than one's own site, for example, in a parking lot where a garage certificate is obtained. This is because it is considered that watching television at the time of charging frequently occurs. Note that a sub screen for displaying information can be displayed on the television by interruption.

Next, in order to immediately convey these messages to the user, the telephone controller 28 performs an automatic dial operation on the mobile telephone 75, and the wireless device 7
2, the mobile phone 75 through the antenna 73 and the repeater 74
A read-out signal is sent to (step S1)
(7)).

At this time, the telephone controller 28 detects off-hook without receiving a busy tone (step S1 (8) not established), and outputs a voice from the user such as "Yes" or "Hello". When it is recognized (step S1 (9) is not established), in other words, the response from the driver (the driver who is the user of the electric vehicle 11) who has detected the ringing sound or vibration based on the read signal by the mobile phone 75. When detected, the above message is notified (step S1 (13)).

After that, the automobile telephone 70 is automatically on-hook to end the message transmission (step S1).
(14)).

Then, as indicated by the path of the connector, the control from the charging abnormality determination in step S1 (2) is repeated.

On the other hand, if the call is busy in the determination in step S1 (8) and there is no response in the determination in step S1 (9), the number of redials is 5
It is determined whether or not it is the first time (step S1 (1
0)), if not, the telephone controller 2
After activating the delay timer of 8 and waiting for 5 minutes ((step S1 (12)), automatic dialing is again performed in the path of the connector (step S1 (7)). This is to inform the user, in other words, to increase the possibility that the user will know.

When the number of redials exceeds 5, the determination in step S1 (10) is established, the transmission of the message by automatic dialing and voice transmission is abandoned, and the automatic voice transmission item is stored in the memory (RAM). It is deleted (step S1 (11)). In addition, until the data is updated,
The data before that may be stored without being deleted. After that, the process returns to step S1 (2) along the path of the connector.

If it is determined in step S1 (4) that there is no automatic transmission item, the portable telephone 75
It is determined whether or not the call signal is sent from the side, that is, the call signal is received by the telephone controller 28 (step S1 (5)). Even if there is no reception, the process returns to step S1 (2) through the path of the connector.

When the telephone controller 28 receives the call signal from the portable telephone 75 in the determination at step S1 (5), the process proceeds to the cipher input step S2 in the entire flowchart.

FIG. 8 is a detailed flowchart of the cipher input step S2.

In this case, first, the voice and / or the display message "Please input the identification number (so-called ID number)" from the car telephone 70 side is reproduced on the mobile telephone 75 side (step. S2 (1)).

In response to this instruction, it is determined whether or not the identification number is actually input (step S2 (2)), and if not input, it is determined whether or not the mobile telephone 75 is on-hook. (Step S2
(3)). If it is on-hook, the process returns to step S1 of the standby mode, and if it is not on-hook,
It is again confirmed whether or not the identification number has been input (again, step S2 (2)).

When the input of the tone signal is confirmed in step S2 (2), it is recognized as the identification signal by the tone signal (step S2 (4)), and when the voice is input, it is recognized as the identification signal by the voice. (Step S2 (5)).

FIG. 9 shows an example of a cipher input mode. That is, the input start is represented by "Angou" in voice input, and in tone signal input, in this example, whether or not the "#" key in the mobile phone 75 is pressed. Then, the input of the personal identification number is performed by inputting a four-digit number, and the identification of the personal identification number is from 0 to 9 in the case of voice input, for example, "Sango na Nana" = 35.
It is recognized in the order in which the names such as 77 are made, and in the tone signal, it is recognized in the order in which the dial keys 0 to 9 are pressed, for example, the order in which the key input such as "3577" is made.

Next, it is judged whether or not the identification number thus input matches the personal identification number stored in advance in the telephone controller 28, that is, whether or not it matches (step S (6)). ).

When the matching of this cipher input is non-matching,
The process returns to step S2 (1) again and prompts the user to enter a code.
At this time, the message "The entered personal identification number is wrong. Please enter the correct personal identification number again." May be changed. On the other hand, if they match, the vehicle information display step S3 in the overall flowchart
Move to.

FIG. 10 shows a display step S of this vehicle information.
Display contents in 3 (hereinafter, unless otherwise specified, the display contents also represent voice message contents)
Shows an example of. Actually, in the vehicle information display step S3, the temperature of the battery 12, the scheduled charging start time, the amount of charge, the room temperature of the vehicle, and the operation mode of the electric air conditioner 31 are checked. , Here, in order to avoid complexity, the steps of importing such information are omitted.

Then, this vehicle information display step S3
Then, in connection with the detection of the abnormal state in the above-mentioned charging abnormality determination step S1 (2), "the power source has not been connected, it has stopped.", "It has stopped due to a system error." A mischief has occurred against. "Etc. is displayed.

Regarding the detection of the charge state, "Because the battery temperature is high, the battery is waiting for charging. Currently, the charge amount is X%.", "Because it is before the scheduled charging start time, it is waiting for charging. Amount of charge is X%, estimated time to complete charging is Y. ”,“ Charging is in progress. Amount of charge is X%, expected time to complete charging is Y. ”,“ Charge completed ”is displayed. I do. Note that the scheduled charging start time is set when the battery is charged using late-night power, which is inexpensive, or when the battery is charged on holidays, the capacity decreases due to self-discharge after full charge. This is because it is desired to complete the charging just before the boarding time when it is desired to prevent the above, or when it is desired to prevent the capacity from decreasing due to a decrease in the temperature of the battery 12 (battery temperature) after charging in cold weather.

Further, regarding the detection of the air conditioner state,
"Room temperature is Z °. Air conditioner is waiting by pre-air conditioner timer.", "Room temperature is Z °. Air conditioner is operating.", "Room temperature is Z °. Air conditioner is stopped." Display the displayed contents.

When the display of the display contents of the vehicle information is completed, the process proceeds to the next command input step S4 in the entire flowchart.

FIG. 11 shows a detailed flowchart of the command input step S4, and FIG. 12 shows a list of the commands, that is, commands.

In this command input step S4, first, the telephone controller 28 instructs the portable telephone 75 to input a command by voice or tone signal. * 0 for vehicle information (in case of voice input Enter the "asterisk zero"), * 1 for charge management, * 2 for air conditioner management. Message is sent (step S4 (1)), and it is monitored whether there is a command input from the user (step S4).
(2)). If there is no command input, it is monitored whether or not it is on-hook (step S4 (3)), and if it is not on-hook, it waits for command input (again,
In step S4 (2)), if it is on-hook, the process returns to the standby mode in step S1.

In step S4 (2), when there is a command input, it is recognized if it is a tone signal (step S4 (4)), and if it is a voice, it is recognized. (Step S4 (5)).

Then, it is confirmed whether the recognized tone signal or voice agrees with the contents of the command input previously stored in the memory of the telephone controller 28 (step S4 (6)), and until it agrees, Step S4
(1) to step S4 (6) are repeated. If the contents match the command input stored in the memory, the operation proceeds to the next operation mode determination step S5. Although not shown in the figure because the flow chart becomes complicated, the number of determinations for confirming the match with the command input content in step S4 (6) is set to a predetermined number, and the predetermined number of times and the command input content do not match. In such a case, the user is notified to return to the standby mode and then returns to the standby mode.

In this step S4, step S4
The command input (command input) in (2) is, as shown in FIG. 12, in the case of a command input related to information display when it is desired to display information on the mobile phone 75,
"Jhoho" voice input or "* 0" key input,
That is, it is an input by a tone signal, in the case of a command input related to charging, it is a voice input such as "Juden" or a key input such as "* 1", and in the case of a command input related to an air conditioner, Voice input such as "air conditioner" or key input of "* 2".

Next, step S5 of the overall flow chart.
Then, if the operation mode is determined based on the determination result of the command match determination (step S4 (6)) and the command input is that the vehicle information display is desired, step S3 is performed.
Returning to the vehicle information display step, if the command is input to the air conditioner controller 21, step S
If the command is input to the charging controller 15, the process proceeds to the air conditioning control of No. 6, and the process proceeds to the charging control step of step S7.

FIG. 13 is a detailed flowchart of the air conditioner control in step S6.

Therefore, first, information on the air conditioner is displayed (step S (1)). This display content is shown in FIG.
Of the vehicle information displays shown in, it relates to the air conditioner. Specifically, as mentioned above, "Room temperature is Z °.
The air conditioner is waiting by the timer. , "Room temperature is Z °
is. The air conditioner is working. "The room temperature is Z °."
The air conditioner is stopped. The display contents of "" are displayed.

Based on the display of this information, the user inputs an appropriate command from the mobile phone 75. Prior to the command input, the input method is indicated by a voice message or display (step S6 (2 )). Specifically, "Please input the command by voice or tone signal. To start the operation, use the voice input of" Kaishi "or the key input of" 1 ", and to stop the operation, If you want to operate "Shi" voice input or "2" key input, and if you want to operate in the air conditioning priority mode, enter "Yusen mode" voice input or "3" key input. Is displayed. In the air conditioner priority mode, the output current of the charger 25 or the like is set to the battery 1
The electric air conditioner 31 is operated so as to be preferentially distributed to the electric air conditioner 31 rather than being charged to the second electric charge. The operation is such that it is operated (see Japanese Patent Application No. 6-201164). When controlled in this way, the electric air conditioner 31 can be operated even in the first-stage charge control state described above.

Next, it is monitored which command is input (step S6 (3)). If there is no command input and the device is not on-hook, the monitoring of whether or not there is a command input is continued, and if it is on-hook, the process returns to step S1 of the standby mode (step S6 (4)).

When there is a command input by voice, the content of the voice is recognized (step S6 (5)), and when there is a command input by the tone signal, the content of the tone signal is recognized. (Step S6 (6)).

Thereafter, when the content of the command input does not match the content set in the telephone controller 28 in advance (step S6 (7) is not established), the step S6 is executed again.
6 (1) to step S6 (7) are repeated, and if they match (step S6 (7) is established), a voice message “air conditioner” is given based on the contents of the match, that is, air conditioner start, air conditioner stop, and air conditioner priority. Has started. ”(Step S6 (8)),“ air conditioner stopped. ”(Step S6 (9)) or“ changed to air conditioner priority mode ”(step S6 (10)). The electric air conditioner 3
1 operation start (step S6 (11)), operation stop (step S6 (12)) or switching to the air conditioner priority mode (step S6 (13)) is performed, and the process proceeds to the next step S7 in the overall flowchart. To do.

FIG. 14 is a detailed flowchart of the charge control in step S7.

First, the charging information is displayed (step S7 (1)). This display content relates to charging in the vehicle information display shown in FIG. 10, and specifically,
As mentioned above, "The battery temperature is high, waiting for charging. Currently, the amount of charge is X%.", "I am waiting for charging because it is before the scheduled start time of charging. The amount of charge is X%, estimated time of completion of charging. Is Y. "," Charging is in progress. The amount of charge is X%, the scheduled charging completion time is Y. "," Charge is completed. "

Based on the display of this information, the user inputs an appropriate command. Before inputting this command,
The input method is indicated by a voice message or display (step S7 (2)). Specifically, "Please input the command by voice or tone signal. To start the operation, use the voice input of" Kaishi "or the key input of" 1 "to stop the operation. Please enter the voice input of "ishishi" or the key input of "2". The display content of "" is displayed.

Next, it is monitored whether or not an instruction is input (step S7 (3)). If there is no command input (step S7 (3) is not established) and it is not on-hook (step S7 (4)), monitoring of whether or not there is a command input is continued, and if it is on-hook (step S).
7 (4)), the process returns to step S1 in the standby mode.

When there is a command input by voice, the content of the voice is recognized (step S7 (5)), and when there is a command input by the tone signal, the content of the tone signal is recognized. (Step S7 (6)).

Thereafter, when the content of the command input does not match the content set in the telephone controller 28 in advance (step S7 (7) is not established), the step S7 is executed again.
7 (1) to step S7 (7) are repeated. If they match (established in step S7 (7)), the voice message “charging has started.” (Step S7 (8)) based on the content of the match, that is, charging start or charging stop.
Or "Charging has been stopped." (Step S7
(9)) is sent to the mobile phone 75 side, and the charging of the battery 12 by the charger 25 or the charger 62 is started (step S7 (10)) or stopped (step S7 (11)).

The on-hook of the user's mobile phone 75 is monitored by the phone controller 28 (step S
7) If not on-hook (step S7 not established)
Then, the process returns to the step S4 of inputting a command, and when the command is on-hook (established in step S7), a series of operations is ended. After this, the process returns to step S1 in the standby mode.

As described above, according to the above-described embodiment, the commercially available general-purpose portable telephone 75 or the home telephone 76 is used as the input / output operation terminal for the automobile telephone 70 of the electric vehicle 11. Therefore, even when the dedicated remote control key 45 is not carried, the charging operation and the operation of the air conditioner can be performed even in a remote place far away from the electric vehicle 11.

In this case, by adopting the cryptographic input method by the voice from the mobile phone 75 or the cryptographic input method by the tone signal, a specific operator (driver, user) can operate before the operation of the pre-air conditioner or the like is started. Since it is recognized that there is something, it is possible to prevent erroneous operations such as mischief.

Further, the operating states of the chargers 25 and 62 and the state of the battery 12 are detected to determine whether or not charging is currently being performed, whether or not charging is completed, in other words, a fully charged state. Whether the battery is present, the amount of charge of the battery 12, and the charging completion time can be known by the mobile phone 75 or the like even in a remote place.

Furthermore, the temperature inside the vehicle and the electric air conditioner 3
After confirming the operating state of No. 1, the operation of the electric air conditioner 31 can be changed and controlled from a remote place by a timer other than the timer arranged in the air conditioner controller 21 of the electric vehicle 11.

In particular, even when the scheduled boarding time is unknown at the time of parking, the electric air conditioner 31 can be operated from a remote location at a time when the scheduled boarding timing is known, even from a remote building, not in a remote location, by the so-called pre-air conditioning function. It can be operated so that it is always comfortable and air-conditioned.
You can get on 1.

Even when the charging is terminated or the charging is accidentally interrupted due to a power failure, a mischief, etc., those things can be immediately and automatically notified to the user by using the car telephone 70 by voice or display. Thereby, for example, when charging at home, the user can call a family member or an acquaintance at home to see the state of the electric vehicle 11. Further, when the housekeeper or the like sees the situation, it is possible to give an appropriate instruction, for example, "I think that the plug (26) is disconnected, so I want you to connect it if it is disconnected". If there is a power outage, the user himself / herself will use the mobile phone 75 after an appropriate time.
The charging can be restarted by.

Furthermore, when the running motor 38 is started during parking, the user can be automatically notified by telephone to inform that the electric vehicle 11 (own vehicle) is mischievous. . As a result, the user can immediately rush to the parking place of the electric vehicle 11. You can also ask over the phone to have family members rush to you.

In this case, the mobile phone 75
It is also possible to control the motor controller 27 of the electric vehicle 11 to stop the traveling, for example.

Further, the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various configurations can be adopted.
