Description

  The present invention relates to a hybrid vehicle, and more particularly to a hybrid vehicle capable of supplying power from a battery to the outside of the vehicle.

  In recent years, since the capacity of the battery of a hybrid vehicle is relatively large, when using electric equipment for camping and outdoor work, or in a power station, a substation, and a transmission station due to a natural disaster such as an earthquake or a tsunami. A technology has been proposed that allows power to be supplied to the outside using this hybrid vehicle, for example, in the event of an emergency where power is no longer supplied due to a failure in power supply equipment such as electric wires.

  Conventionally, as this kind of hybrid vehicle, for example, one disclosed in Japanese Patent Application Laid-Open No. 2017-210178 is known. In this method, a battery is charged from the outside via a charging connector, and is driven using the power of the battery.A recess which can be opened and closed with a lid is formed outside the body, and the recess is charged in the recess. A connector is provided. In addition, in this recess, a plug connected to various electric devices is inserted separately from the charging connector, and a power outlet that is wired to the battery and supplies power to the battery is provided. When using the power outlet, the lid is opened, plugs connected to various electric devices are inserted into the power outlet, and power is supplied from a battery to be used.

JP 2017-210178 A

  However, in this conventional hybrid vehicle, since the battery is charged from the outside via the charging connector, only the power of the battery can be used for power supply. . By the way, in a hybrid vehicle, there is a type in which a generator is driven by operating a gasoline engine to generate electric power, and the electric power is stored in a battery for use. If the power outlet as described above is provided, power can be supplied by further using the power generated by operating the engine, so that power supply for a relatively long time can be expected as compared with the type of charging from outside. However, even in this type, the power supply available time is not always sufficient because it depends on the amount of gasoline supplied to the gasoline tank. For example, in the event of an emergency where power is no longer supplied due to the failure of power supply facilities such as power stations, substations, and transmission lines due to the effects of natural disasters such as earthquakes and tsunamis as described above, It is not always enough to limit use.

  The present invention has been made in view of such a problem, and an object of the present invention is to provide a hybrid vehicle in which the power supply available time of the external power supply is significantly increased.

  In order to achieve such an object, the inventors of the present application have focused on a bifuel type automobile. In recent years, for example, gas-fueled vehicles using gas fuels such as LPG and LNG have been widely used mainly for business vehicles such as taxis because the fuel unit price is lower than gasoline fuel and the cost is advantageous. I have. On the other hand, a gas-fueled vehicle may be inferior to a gasoline vehicle in engine operability when the engine is started or in an early stage of running, particularly when the outside air temperature is low, or during an overload operation. Therefore, in order to solve this problem, vehicles equipped with a bi-fuel type fuel supply device capable of switching between gas fuel and gasoline fuel have been widely used (for example, Japanese Patent Application Laid-Open No. 2017-40334). ).

The hybrid vehicle of the present invention has been made with a focus on this bifuel type vehicle, and in order to achieve the above object, a liquid fuel tank storing liquid fuel in a vehicle body, and a liquid fuel tank supplied from the liquid fuel tank. An engine operable by burning liquid fuel and operating by burning gaseous fuel, a generator for generating power by the power of the engine, and a high-voltage battery for storing electricity generated by the generator. An electric motor operated by electricity supplied from the high-voltage battery, and a hybrid vehicle that runs the vehicle body using the power of the engine and the electric motor as a power source.
On the vehicle body, a gas fuel cylinder for storing gaseous fuel, and a fuel supply unit for switching and supplying liquid fuel from the liquid fuel tank and gaseous fuel from the gaseous fuel cylinder to the engine, respectively,
A power supply circuit is provided on the outside of the vehicle body so as to expose a power outlet into which an electric plug connected to an external electric device can be inserted, and a power supply circuit for supplying power of the high-voltage battery to the power supply outlet is provided in the vehicle body. The configuration is provided.

That is, in the present invention, a hybrid vehicle using power of an engine that operates by burning liquid fuel and an electric motor that is obtained from the power of the engine and is operated by electricity stored in a high-voltage battery is used as a power source. In addition, a gas fuel cylinder is mounted, and a fuel supply unit for switching and supplying the liquid fuel from the liquid fuel tank and the gas fuel from the gas fuel cylinder to the engine, respectively, is mounted, and is configured as a bifuel type hybrid vehicle. A bi-fuel hybrid vehicle is provided with a power outlet capable of supplying electricity from a high-voltage battery to the outside via a power supply circuit.
Here, examples of the liquid fuel include gasoline, light oil, alcohols (methanol, ethanol, and the like). Examples of the gaseous fuel include liquefied natural gas (LNG) and liquefied petroleum gas (LPG). An engine that can handle both liquid fuel and gaseous fuel is mounted.

  Thus, when using the power outlet, the power outlet is exposed to the outside of the vehicle body, and an electric plug connected to an electric device is inserted into the power outlet. Then, power is supplied from the high-voltage battery through the power supply circuit, and the battery is used. In this case, the electricity stored in the high-voltage battery is electricity generated by the generator by the motive power of the engine, but the engine is supplied with the liquid fuel from the liquid fuel tank and the gas from the gaseous fuel cylinder through the fuel supply unit. Gaseous fuel is switched and supplied. Therefore, not only the liquid fuel in the liquid fuel tank but also the gas fuel in the gas fuel cylinder can be used as an energy source, so that the power supply available time of the external power supply can be greatly increased.

  That is, in the case of only the liquid fuel, the power supply available time depends on the amount of the liquid fuel supplied to the liquid fuel tank, and thus is not always sufficient, but in the present invention, the gas fuel of the gas fuel cylinder is also used as an energy source. Because it can be used, it can be twice as long. For example, the power supply facilities such as power plants, substations, and transmission lines are damaged by the effects of natural disasters such as earthquakes and tsunamis. In the event of an emergency in which supply is no longer available, the time required for rescue and the like can be extra, which is extremely useful.

  And, if necessary, the power supply circuit converts the high-voltage DC current from the high-voltage battery into a low-voltage DC current to transmit power, and converts the low-voltage DC current from the converter into a low-voltage AC current to convert the power supply into a low-voltage AC current. An inverter for transmitting power to the outlet is provided. Thereby, for example, the working voltage of the power outlet can be set to 100 V of general electric equipment, and the versatility can be increased.

  Further, if necessary, a control unit for controlling the inverter is provided, and a voltage sensor for detecting a voltage in a power supply circuit downstream of the inverter is provided. The control unit is configured to control the inverter based on a detection result of the voltage sensor. Is provided with an inverter control means for controlling the inverter so as to output a power of a predetermined supply voltage value from the power supply. Thus, it is possible to supply a stable voltage, for example, a power of 100 V AC. . The supply voltage value may be a voltage value having a certain width.

  Further, if necessary, an alarm device which is activated by the vehicle body to generate an alarm is provided, and a current sensor for detecting a current is provided in a power supply circuit on the downstream side of the converter, and the control unit has a predetermined rating. Rated current value storage means for storing a current value; rated current value determination means for determining whether the current value detected by the current sensor is equal to or less than the rated current value stored by the rated current value storage means; An abnormal signal sending means for sending an abnormal signal when the rated current value judging means judges that the rated current value has been exceeded; and an alarm device which operates the alarm device when the abnormal signal is sent from the abnormal signal transmitting device. And an alarm generating means for generating an alarm. Thereby, for example, when the electric equipment connected to the power outlet is used exceeding the rated current and becomes overcurrent, the abnormal signal is transmitted from the abnormal signal transmitting means, and the alarm generating means outputs the alarm signal. Will issue an alert. Therefore, excessive use of electric equipment can be suppressed, and safety can be achieved.

  In this case, the control unit is configured to stop the operation of the alarm device when the rated current value determination unit determines that the current value is equal to or less than the rated current value while the alarm generation unit is operating the alarm device. It is effective to have the means. Thereby, for example, when the electric device connected to the power outlet is used in excess of the rated current, when a notice of the alarm of the alarm device is noticed, and the use of the electric device is suppressed and addressed, Since the alarm stops, safety can be confirmed.

  Further, if necessary, the control unit may further include a dangerous current value storage unit that stores a dangerous current value higher than the predetermined rated current value and a rated current value determining unit that determines that the rated current value has exceeded the rated current value. Dangerous current value determining means for determining whether the current value detected by the current sensor is equal to or less than the dangerous current value stored in the dangerous current value storage means, and the dangerous current value determining means exceeds the dangerous current value. And a shut-off means for shutting off the function of the inverter when it is determined that the inverter has failed. Thus, when dangerous use of an electric device that greatly exceeds the rated current value is performed, the power supply itself can be stopped, so that safety can be further ensured.

  Further, if necessary, the control unit stores an appropriate appropriate voltage value range defined by a predetermined upper limit voltage value that is predetermined and higher than the supply voltage value and a predetermined lower limit voltage value that is lower than the supply voltage value. An appropriate voltage value range storage means, and an appropriate voltage value range determination means for determining whether the voltage value detected by the voltage sensor is within the appropriate voltage value range stored by the appropriate voltage value range storage means or outside the appropriate voltage value range. The abnormal signal transmitting means has a function of transmitting an abnormal signal when the appropriate voltage value range determining means determines that the abnormal voltage value is out of the appropriate voltage value range. For example, the load on the electric device connected to the power outlet increases, and the voltage becomes lower than the lower limit voltage, or power is supplied from the side of the electric device connected to the power outlet, and the voltage becomes higher than the upper limit voltage. When such an unexpected situation occurs, an abnormal signal is transmitted from the abnormal signal transmitting means, and an alarm is issued from the alarm device by the alarm generating means. Therefore, it is possible to respond to an unexpected situation, and safety can be further improved.

  In this case, the control unit stops the operation of the alarm device when the appropriate voltage value range determination unit determines that the voltage is within the appropriate voltage value range while the alarm generation unit is operating the alarm device. It is effective to provide an alarm stopping means. Thus, when the alarm is noticed by the alarm and the unforeseen situation is resolved, the alarm stops and the safety can be confirmed.

  Further, as required, the alarm device is configured to be at least one of a permanent hazard lamp mounted on the vehicle body and a permanent security buzzer mounted on the vehicle body. Since a device permanently installed in a vehicle is used as an alarm device, it is not necessary to separately provide an alarm device, and the efficiency of parts and wiring is extremely improved.

  Further, according to the present invention, a gas outlet to which a gas pipe connected to an external gas appliance can be exposed is provided outside the vehicle body as required, and the gas fuel cylinder is provided inside the vehicle body. And a gas pipe for supplying the above gas to the gas outlet. Thus, when using a gas outlet, the gas outlet is exposed to the outside of the vehicle body, and various gas appliances such as a stove are connected to the gas outlet via a gas pipe. In this case, the gas supplied to the gas equipment is a gas from a gaseous fuel cylinder, and can be used without preparing a separate gas source, which is extremely convenient. In particular, it becomes extremely useful in the case of an emergency in which a general gas source is lost due to a natural disaster such as an earthquake or tsunami.

  In addition, if necessary, a gas outlet to which a gas pipe connected to an external gas device can be exposed and provided outside the vehicle body, and a gas cylinder different from the gas fuel cylinder is provided inside the vehicle body. And a gas pipe for supplying the above gas to the gas outlet. The energy of the gaseous fuel cylinder is used as electricity, and another gas cylinder can be used for gas. In this case, versatility can be improved by using a gas stove for a tabletop gas stove that has been widely used in recent years.

  Further, in the present invention, if necessary, a water generator for generating water from the atmosphere is mounted on the vehicle body, and a water supply port is provided on the outside of the vehicle body so as to be exposed, and inside the vehicle body. And a water pipe for supplying water from the water generator to the water supply port. Thereby, the water generated by the water generator from the water supply port can be used. Since the water in the water generator is produced from the atmosphere, it can be used as drinking water, which is extremely useful in cases where water is not available nearby. In particular, it becomes extremely useful in the case of an emergency in which general water resources are limited due to the effects of natural disasters such as earthquakes and tsunamis.

  According to the present invention, when using a power outlet, the power outlet is exposed to the outside of the vehicle body, and an electric plug connected to an electric device is inserted into the power outlet.

  Further, the hybrid vehicle HV according to the embodiment, as shown in FIGS. 1 (a), 2, 7 and 8, is located outside the vehicle body 1 and has a liquid fuel supply port 22 and a gas fuel supply port 22.

  Therefore, when the power outlet 30 is used by the hybrid vehicle HV according to the embodiment, the cap 36 is opened to expose the power outlet 30 to the outside of the vehicle body 1, and the power outlet 30 is connected to an electric device connected to an electric device. Insert the plug 40. Then, power is supplied from the high-voltage battery 5 via the power supply circuit 50 and used for use. Referring to the flowchart shown in FIG. 6, in the power supply circuit 50, at the time of power supply, the voltage is detected by the voltage sensor 55 (S 1), the current is detected by the current sensor 56, and the current is detected by the inverter control means 61 of the control unit 60. The inverter 53 is controlled such that the inverter 53 outputs power of a predetermined supply voltage value (AC 100 V in the embodiment) based on the detection result of the voltage sensor 55 (S2).

  Then, the rated current value determining means 63 determines whether the current value detected by the current sensor 56 is equal to or less than the rated current value stored in the rated current value storage means 62 (S3). The value range determining means 71 determines whether the voltage value detected by the voltage sensor 55 is within the proper voltage value range stored by the proper voltage value range storage means 70 or outside the proper voltage value range (S4). If the determination means 63 determines that the current is not more than the rated current value (S3 Yes), and if the appropriate voltage value range determination means 71 determines that the current is within the appropriate voltage value range (S4 Yes), the power of the predetermined supply voltage value is regarded as normal. Is consumed. The inverter 53 is controlled by the inverter control unit 61 based on the detection result of the voltage sensor 55 so that the inverter 53 outputs power of a predetermined supply voltage value. For example, it is possible to stably supply 100 V AC power. it can.

  In this case, the electricity stored in the high-voltage battery 5 is electricity generated by the generator 4 by the motive power of the engine 3, but is supplied to the engine 3 from the liquid fuel tank 2 through the fuel supply unit 11. The liquid fuel and the gaseous fuel from the gaseous fuel cylinder 10 are respectively switched and supplied. Therefore, not only the liquid fuel in the liquid fuel tank 2 but also the gaseous fuel in the gaseous fuel cylinder 10 can be used as an energy source, so that the power supply available time of the external power supply can be greatly increased. That is, in the case of using only the liquid fuel, the power supply available time depends on the amount of the liquid fuel supplied to the liquid fuel tank 2 and thus is not always sufficient, but in the embodiment, the gas fuel of the gas fuel cylinder 10 is also not sufficient. Since it can be used as an energy source, it can be used twice as long. Therefore, for example, in the event of an emergency in which power is no longer supplied due to the failure of power supply facilities such as power stations, substations, and transmission lines due to the effects of natural disasters such as earthquakes and tsunamis, This is extremely useful because the required time can be extra.

  In this use, if the rated current value determination means 63 determines that the current value detected by the current sensor 56 exceeds the rated current value stored in the rated current value storage means 62 (S3No), the abnormal signal transmission means 64 An abnormal signal is transmitted (S5), and the alarm generating means 65 activates the alarm 57 to generate an alarm from the alarm 57 (S6). For example, when an electrical device connected to the power outlet 30 is used in excess of the rated current and becomes overcurrent, an abnormal signal is transmitted from the abnormal signal transmitting means 64 and an alarm device 65 outputs an alarm signal. An alarm is issued from 57. Therefore, excessive use of electric equipment can be suppressed, and safety can be achieved.

  If the rated current value discriminating means 63 determines that the alarm current is not more than the rated current value while the alarm generating means 65 is operating the alarm 57 (S7 Yes), the alarm stopping means 66 stops the operation of the alarm 57 (S8). ), Return to the normal power supply state, for example, when the electric device connected to the power outlet 30 is used exceeding the rated current, the alarm of the alarm device 57 notices and the use of the electric device is suppressed. If the countermeasures are taken, the alarm stops, so that safety can be confirmed and continuation of use can be ensured.

  If the rated current value determining means 63 determines that the current exceeds the rated current value while the alarm generating means 65 operates the alarm device 57 (S7 No), the dangerous current value determination is performed in this state. The means 68 determines whether the current value detected by the current sensor 56 is equal to or less than the dangerous current value stored in the dangerous current value storage means 67 (S9), and the dangerous current value determining means 68 determines If it is determined (S9 Yes), the alarm device 57 continues to operate, but if the dangerous current value determining means 68 determines that the dangerous current value has been exceeded (No in S9), the shut-off means 69 turns off the inverter 53. The function is cut off (S10). Thus, when dangerous use of an electric device that greatly exceeds the rated current value is performed, the power supply itself can be stopped, so that safety can be further ensured.

  Also, even if the rated current value determining means 63 determines that the current is not more than the rated current value (S3 Yes), if the appropriate voltage value range determining means 71 determines that the voltage is out of the appropriate voltage value range (S4 No), an abnormal signal is transmitted. An abnormal signal is transmitted from the means 64 (S11), and the alarm generating means 65 activates the alarm 57 to generate an alarm from the alarm 57 (S12). For example, the load of the electric device connected to the power outlet 30 increases and becomes lower than the lower limit voltage, or power is supplied from the side of the electric device connected to the power outlet 30 and the overvoltage exceeds the upper limit voltage. When an unexpected situation occurs, an abnormal signal is transmitted from the abnormal signal transmitting means 64, and an alarm is issued from the alarm device 57 by the alarm generating means 65. Therefore, it is possible to respond to an unexpected situation, and safety can be further improved.

  Also in this case, when the appropriate voltage value range determining means 71 determines that the alarm voltage is within the appropriate voltage value range while the alarm generating means 65 operates the alarm 57 (S13 Yes), the alarm stopping means 66 activates the alarm 57. Is stopped (S14), and the state returns to the normal power supply state. Thereby, when the alarm 57 is noticed by the alarm and the unexpected situation is resolved, the alarm stops and the safety can be confirmed.
