  However, Patent Document 1 does not describe any method for generating electric power by operating an internal combustion engine. In addition, in the power supply method described in Patent Document 2, no consideration is given to the remaining amount of fuel for operating the internal combustion engine. Therefore, in the power supply methods described in Patent Documents 1 and 2, there is a problem that if the internal combustion engine is operated to supply power, the fuel may run out during power supply. In addition, when the fuel runs out and the charging rate is low, there is a problem in that the electric vehicle that has supplied electric power cannot run on its own.

  Therefore, the present invention is an invention made under the state of the prior art as described above, and is capable of supplying electric power to the outside and running out of fuel necessary for the operation of the internal combustion engine of the vehicle that supplies the electric power.

However, the scope of the present invention is not limited to the following embodiments. The dimensions, materials, shapes, relative arrangements, and the like of the components described in the following embodiments are merely illustrative examples and are not intended to limit the scope of the present invention only unless otherwise specified. Moreover, in the following description, although the case where a series system vehicle is used as a hybrid vehicle will be described, the present invention is not limited to this system.

FIG. 1 is a schematic diagram showing a state in which electric power is supplied from an electric vehicle (passenger car) in which the charging rate of the battery is lowered and becomes unable to self-run from the hybrid vehicle according to the embodiment of the present invention.
As shown in FIG. 1, electric power is supplied by connecting a discharging cable 2 of a hybrid vehicle 1 to a charging socket (not shown) of an electric vehicle 4 for rescue. In the following embodiment, the case where electric power is supplied from the hybrid vehicle 1 to the electric vehicle 4 will be described, but the supply destination of electric power is not limited to the electric vehicle 4.

FIG. 2 is a block diagram showing the configuration of the hybrid vehicle 1.
As shown in FIG. 2, the hybrid vehicle 1 includes a storage battery 6, a control unit 8 for controlling the storage battery 6, a motor 10 (electric motor) that operates by discharging from the storage battery 6, and a charging rate of the storage battery 6. An engine 12 (internal combustion engine) that is operated when the engine pressure is reduced, and a generator 14 that is operated by the engine 12.

  The hybrid vehicle 1 is a so-called series-type vehicle that operates the engine 12 and the generator 14 to charge the capacitor 6 when the charging rate of the capacitor 6 decreases and continues the motor running.

  The control unit 8 includes an arithmetic unit (not shown) including an inverter 16, a charge rate detection unit 18, a storage battery determination unit 20, a storage battery discharge unit 22, a DC / DC converter 24, an AC / DC converter 25, and a CPU. And). Further, the control unit 8 has a storage unit (not shown) such as a ROM and a RAM in which software programs for realizing these means are recorded, and an arithmetic unit is stored in the storage unit as necessary. The following means are realized by reading and executing the program.

  During normal traveling, the electric power of the battery 6 is converted from direct current to alternating current by the inverter 16 and supplied to the motor 10 for traveling the hybrid vehicle 1.

The charging rate detection unit 18 of the control unit 8 detects the charging rate of the battery 6 and outputs the detected charging rate to the battery determination unit 20.
Receiving the charging rate output from the charging rate detection unit 18, the battery determination unit 20 determines that electric power can be supplied to the electric vehicle 4 when the charging rate is equal to or higher than a preset second threshold value.
Then, when determining that the electric power can be supplied to the electric vehicle 4, the battery determination unit 20 outputs the determination result to the battery discharge unit 22.
On the other hand, if the storage battery determination unit 20 determines that electric power cannot be supplied to the electric vehicle 4, the storage battery determination unit 20 outputs the determination result to the fuel determination unit 42 described later.

When receiving the determination result that the electric power can be supplied from the electric storage device determination unit 20, the electric storage device discharging unit 22 discharges the electric power from the electric storage device 6 and supplies the electric vehicle 4 with electric power. At this time, the electric power discharged from the battery 6 is converted into a voltage capable of charging the electric vehicle 4 by the DC / DC converter 24 and supplied to the electric vehicle 4 via the supply means 26.
Next, the supply means 26 will be described.

The supply means 26 includes a charge / discharge connector 28 connectable to a charging socket of the electric vehicle 4, a discharge cable 2 having one end connected to the charge / discharge connector 28 and the other end connected to the control unit 8, And a relay switch 30 provided in the middle of the discharging cable 2.
The storage battery discharging means 22 controls the on / off state of the relay switch 30, whereby the power from the storage battery 6 can be supplied to the electric vehicle 4. The initial state of the relay switch 30 is an off state. When the storage battery discharging unit 22 receives the determination result indicating that the power can be supplied from the storage battery determination unit 20, the storage battery discharge unit 22 controls the relay switch 30 to be in an ON state.

The discharge cable 2 is provided with an ammeter 34, and the current value is always measured while supplying electric power to the electric vehicle 4. The measured current value is output to the power supply stopping unit 46 described later.
By the way, when charging of the electric storage device on the electric vehicle 4 side is completed, no current flows through the discharging cable 2. Therefore, by measuring the current flowing through the discharge cable 2 with the ammeter 34, it is possible to detect the completion of charging of the battery of the electric vehicle 4.

When the current value measured by the ammeter 34 is equal to or lower than a preset first threshold value, the power supply stopping unit 46 determines that the charging of the battery on the electric vehicle 4 side has been completed, and sends a charge completion signal to the battery discharging unit. 22 to output.
When receiving the charging completion signal from the power supply stopping unit 46, the battery discharging unit 22 controls the relay switch 30 to be turned off to stop the power supply from the battery 6.

  Next, a description will be given of a method of supplying the electric vehicle 4 with electric power generated by operating the generator 14 by the engine 12 when the charging rate of the battery 6 is less than the second threshold.

The hybrid vehicle 1 includes a fuel tank 36 for storing fuel for operating the engine 12, fuel detection means 38 for detecting the remaining amount of fuel in the fuel tank 36, and an ECU 40 for controlling the engine 12 and the like. Are further provided.
The fuel detection means 38 outputs the detected remaining amount of fuel to the fuel determination means 42 in the ECU 40.

  The ECU 40 includes a fuel determination unit 42, an internal combustion engine drive unit 44, and a power supply stop unit 46.

When the fuel determination unit 42 receives the determination result that the electric power cannot be supplied from the electric storage unit 6 as a result of the determination by the electric storage unit determination unit 20, the fuel determination unit 42 based on the remaining amount of fuel detected by the fuel detection unit 38. It is determined whether or not electric power can be supplied to the electric vehicle 4 by operating the electric motor 14 with the driving force.
The fuel determination unit 42 determines that electric power can be supplied when the remaining amount of fuel is equal to or greater than a preset third threshold value.

When the fuel determination unit 42 determines that electric power can be supplied to the electric vehicle 4, the fuel determination unit 42 outputs the determination result to the internal combustion engine drive unit 44.
On the other hand, if the fuel determination means 42 determines that power cannot be supplied to the electric vehicle 4, the fuel determination means 42 turns on the warning lamp 48. In this embodiment, the case where the warning lamp 48 is turned on has been described as a method for notifying that power cannot be supplied. However, the present embodiment is not limited to this, and the empty lamp of the hybrid vehicle 1 is used. It is good also as making it light.

  When the internal combustion engine drive means 44 of the ECU 40 receives the determination result indicating that the electric power can be supplied from the fuel determination means 42, the internal combustion engine drive means 44 operates the engine 12 and the generator 14, and sets the relay switch 30 on / off. It controls and supplies electric power to the electric vehicle 4. Specifically, the internal combustion engine drive unit 44 controls the relay switch 30 to be in an ON state upon receiving a determination result indicating that electric power can be supplied from the fuel determination unit 42.

At this time, the electric power supplied from the generator 14 is converted into direct current by the AC / DC converter 25 in the control unit 8 and supplied to the electric vehicle 4 through the supply means 26.
In the present embodiment, the case where the electric power generated by operating the generator 14 is supplied to the electric vehicle 4 via the AC / DC converter 25 of the control unit 8 has been described. However, the present invention is not limited to this. The electric power generated by operating the generator 14 may be temporarily charged in the battery 6 and then discharged from the battery 6 to supply the electric power to the electric vehicle 4.

  When the charging of the electric storage device of the electric vehicle 4 is completed and no current flows through the discharging cable 2 and the current value measured by the ammeter 34 is equal to or lower than the first threshold value, the power supply stopping unit 46 A charge completion signal is output to the internal combustion engine drive means 44 on the assumption that charging of the battery of the automobile 4 has been completed.

  When the internal combustion engine drive unit 44 receives the charge completion signal from the power supply stop unit 46, the internal combustion engine drive unit 44 stops the engine 12 and controls the relay switch 30 to be turned off to stop the power supply from the generator 14.

  A method for charging the battery of the electric vehicle 4 using the hybrid vehicle 1 having the above-described configuration will be described below with reference to a flowchart.

  First, the hybrid vehicle 1 is stopped near the electric vehicle 4 to be rescued, and the discharging cable 2 of the hybrid vehicle 1 is connected to the charging socket of the electric vehicle 4.

  Next, the charging rate detection means 18 of the control unit 8 detects the charging rate Ba of the battery 6 of the hybrid vehicle 1 (step S1). Subsequently, the charging rate detection unit 18 outputs the detected charging rate Ba to the capacitor determination unit 20.

Upon receipt of the charging rate Ba output from the charging rate detection unit 18, the battery determination unit 20 determines whether or not the charging rate Ba is equal to or greater than the second threshold value Bth (step S3).
The storage battery determination unit 20 determines that power can be supplied from the storage battery 6 to the electric vehicle 4 when the charging rate Ba is equal to or greater than the second threshold value Bth.
If it is determined that electric power can be supplied from the battery 6 to the electric vehicle 4, the battery determination unit 20 outputs the determination result to the battery discharge unit 22.
On the other hand, when it is determined that power cannot be supplied from the battery 6 to the electric vehicle 4, the battery determination unit 20 outputs the determination result to the fuel determination unit 42.

  Receiving the determination result indicating that power can be supplied from the storage battery determination unit 20, the storage battery discharge unit 22 controls the relay switch 30 of the supply unit 26 to be turned on (step S5). Thereby, the electric power from the battery 6 can be supplied to the electric vehicle 4. At this time, the electric power discharged from the battery 6 is converted into a voltage capable of charging the electric vehicle 4 by the DC / DC converter 24 and supplied to the electric vehicle 4 via the supply means 26.

On the other hand, the fuel determination means 42 that has received the determination result indicating that power cannot be supplied from the battery determination means 20 detects the remaining amount of fuel Fa by the fuel detection means 38 (step S7).
Subsequently, the fuel determination unit 42 determines whether or not the remaining amount Fa of the fuel detected by the fuel detection unit 38 is equal to or greater than the third threshold value Fth (step S9). The fuel determination unit 42 determines that electric power can be supplied to the electric vehicle 4 by operating the generator 14 with the engine 12 when the fuel remaining amount Fa is equal to or greater than the third threshold value Fth.

When the fuel determination unit 42 determines that electric power can be supplied to the electric vehicle 4, the fuel determination unit 42 outputs the determination result to the internal combustion engine drive unit 44.
On the other hand, if the fuel determination means 42 determines that power cannot be supplied to the electric vehicle 4, the fuel determination means 42 turns on the warning lamp 48 (step S11).

The internal combustion engine drive unit 44 that has received the determination result indicating that the electric power can be supplied from the fuel determination unit 42 controls the relay switch 30 to the ON state and operates the engine 12 and the generator 14 to generate electric power. Supply to the automobile 4 (step S13).
At this time, the electric power supplied from the generator 14 is converted into direct current by the AC / DC converter in the control unit 8 and supplied to the electric vehicle 4 via the supply means 26.

  When the electric discharge generated from the battery 6 or the electric power generated by the generator 14 is supplied to the electric vehicle 4, the current value Ia flowing through the discharging cable 2 is measured by the ammeter 34 (step S15).

And the electric power supply stop means 46 determines whether the electric current value Ia measured with the ammeter 34 is below 1st threshold value Ith (step S17).
When the current value Ia measured by the ammeter 34 is larger than the first threshold value Ith, it is determined that charging of the electric vehicle 4 is not completed, and step S1 for detecting the charging rate of the battery 6 is performed again. To do.
On the other hand, if the current value Ia measured by the ammeter 34 is less than the first threshold value Ith, it is determined that the charging of the electric vehicle 4 has been completed, and the fact that the charging has been completed is indicated by the capacitor discharging means 22 or the internal combustion engine driving means. 44. At this time, the power supply stopping means 46 outputs to the capacitor discharge means 22 when power is supplied from the battery 6, and outputs to the internal combustion engine drive means 44 when power is supplied from the generator 14. To do.

  Receiving the output indicating that charging of the electric vehicle 4 has been completed from the power supply stopping unit 46, the battery discharger 22 or the internal combustion engine drive unit 44 controls the relay switch 30 to be in the OFF state, and discharges from the battery 6 or The engine 12 is stopped and power supply is stopped (step S19).

  As described above, according to the hybrid vehicle 1 according to the present embodiment, it is possible to supply electric power by operating the generator 14 with the battery determination unit 20 that determines whether or not the battery 6 can be discharged and the engine 12. And the fuel determination means 42 for determining whether or not the remaining amount of fuel is equal to or greater than the third threshold when the charge rate of the capacitor 6 is equal to or greater than the second threshold or even when the charge rate of the capacitor 6 is less than the second threshold. In some cases, electric power can be supplied to the electric vehicle 4. Therefore, when the charging rate of the battery 6 is low and the fuel is low, power is not supplied. As a result, it is possible to prevent the hybrid vehicle 1 from running out of fuel due to power supply and being unable to run on its own.

  When the charging of the battery of the electric vehicle 4 is completed, almost no current flows through the discharging cable 2. For this reason, it is possible to detect the completion of charging of the battery of the electric vehicle 4 by measuring the value of the current flowing through the supply means 26 with the ammeter 34. And since the electric power supply stop means 46 which stops the electric power supply from the generator 14 or the electrical storage 6 is provided when the ammeter 34 becomes less than a 1st threshold value, when the engine 12 is operated, for example, the engine 12 Can be stopped. Thereby, useless fuel consumption can be suppressed.

  Moreover, the storage battery determination means 20 can prevent overdischarge of the storage battery 6 by determining that electric power can be supplied to the electric vehicle 4 when the charging rate of the storage battery 6 is equal to or greater than the second threshold. Thereby, it can prevent that the hybrid vehicle 1 becomes self-propelled. Moreover, deterioration of the battery 6 can be suppressed.

And the fuel determination means 42 can prevent running out of fuel by determining that electric power can be supplied to the electric vehicle 4 when the remaining amount of fuel is equal to or greater than a preset third threshold value.
Further, by setting the third threshold value to an amount that allows the vehicle to travel to a fuel supply location that is set in advance by operating the engine 12, the vehicle that has consumed fuel by the operation of the engine 12 self-travels to the fuel supply location. can do. As a result, it is possible to prevent the hybrid vehicle 1 after being rescued from running out of fuel and being unable to run on its own.
