Description

  The present invention relates to vehicle control, and more particularly to control of a hybrid vehicle including a battery that can be externally charged.

  Conventionally, a hybrid vehicle using a power source of at least one of an engine and a motor that operates with electric power supplied from a battery has been put into practical use. In a hybrid vehicle having a battery that can be externally charged, the engine is operated only as an auxiliary, and normally, the engine should not be operated and only a motor without exhaust gas should be operated to travel. That is, it is desirable not to operate the engine except under special circumstances, such as when the vehicle travels only by operating the motor during normal traveling and the vehicle cannot travel without operating the engine without external charging equipment. However, in such a hybrid vehicle, it is possible to run by the engine, so there is a risk that the driver may rely on the running by the engine, and the original purpose of the hybrid vehicle to extend the travelable distance while obtaining the effect of suppressing air pollution We are concerned that we cannot achieve. A technique for solving such a problem is disclosed in, for example, JP-A-8-19114 (Patent Document 1).

  The fuel use-restricted hybrid electric vehicle disclosed in this publication includes a battery that can be charged by an external charging means, a driving motor that can drive wheels by electric power from the battery, and a power generation that can supply power to the driving motor. An internal combustion engine for driving the machine, a detection means for detecting a change in parameter according to the amount of fuel used by the internal combustion engine after the battery is charged by the external charging means, and for controlling the operation of the electric motor and the internal combustion engine Control means. The control means includes means for restricting at least one of the output of the electric motor and the internal combustion engine when the change in the parameter reaches a predetermined value from the detection result of the detection means.

According to the fuel use-restricted hybrid electric vehicle disclosed in this publication, the battery can be charged by the external charging means. When the remaining capacity of the battery is reduced, the internal combustion engine is operated to The wheel can be driven while the generator is driven and the electric power generated by the generator is supplied to the drive motor. However, when the change of the parameter corresponding to the amount of fuel used is detected by the detection means and the change in the parameter reaches a predetermined amount, the control means limits at least one of the output of the electric motor and the internal combustion engine. That is, if the vehicle continues to run while using fuel without external charging, the output of the electric motor or internal combustion engine is limited when the amount of fuel used reaches a certain level, and the driver is charged externally. It encourages them to do so. As a result, even a hybrid electric vehicle can promote traveling without relying on the internal combustion engine, and in the event of an emergency, the hybrid electric vehicle can suppress the air pollution that the hybrid electric vehicle originally intended, while leaving room for the internal combustion engine to travel. Will be able to get enough.
JP-A-8-19114

  In the hybrid electric vehicle disclosed in Patent Document 1, a driver who is prompted to perform external charging can perform external charging by stopping the vehicle at a place having an external charging facility. However, when a fuel refueling facility is further provided in the vicinity of the external charging facility at the stop location, it is conceivable that the external charging operation and the fuel refueling operation are performed simultaneously. In this case, it may be considered that the operator is distracted by the fuel refueling work and cannot concentrate on the external charging work, and overcharges the battery.

The control device is provided between the connector and the power storage mechanism, and switching means for switching the state of the connector and the power storage mechanism to either the electrically connected state or the electrically disconnected state, Detection means for detecting a state relating to refueling and control means for controlling the switching means based on the state relating to refueling are included. The control method according to the eighth invention has the same requirements as the control device according to the first invention.

  According to the first or eighth invention, a state relating to refueling in the vehicle is detected, and based on the detected state, the state of the connector and the power storage mechanism is either an electrically connected state or an electrically disconnected state. Can be switched to. Thereby, for example, when a state in which refueling is performed is detected, the connector and the power storage mechanism can be electrically disconnected. If it does in this way, even if charging / discharging operation | work and oil supply operation | work are performed simultaneously, charging / discharging of an electrical storage mechanism will not be performed. As a result, the internal combustion engine, the fuel filler port to which the fuel supply facility outside the vehicle is connected when fuel for the internal combustion engine is connected, the power storage mechanism, and the power source and electricity outside the vehicle when charging or discharging the power storage mechanism A control device capable of preventing overcharging and overdischarging of a power storage mechanism even when charging / discharging operation and refueling operation are performed at the same time in a vehicle including a connector to which one of loads is connected, and A control method can be provided.

The detection means includes means for detecting the open / closed state of the lid portion for the fuel filler opening. The control means includes means for controlling the switching means based on the open / closed state. The control method according to the ninth aspect has the same requirements as those of the control apparatus according to the second aspect.

  According to the 2nd or 9th invention, a switching means is controlled based on the opening-and-closing state of the cover part for fueling openings. Thereby, for example, when the lid portion for the fuel filler opening is in the open state, it is determined that the fuel filler operation is being performed, and the connector and the power storage mechanism can be electrically disconnected.

  In the control device according to the third aspect of the invention, in addition to the configuration of the second aspect of the invention, the control means controls the switching means so as to be in a shut-off state when the lid portion for the fuel filler is in the open state. Means for. The control method according to the tenth invention has the same requirements as the control device according to the third invention.

  According to the third or tenth aspect of the invention, the connector and the power storage mechanism are electrically disconnected when the fuel filler lid is open. As a result, even if the charging / discharging operation and the refueling operation are performed simultaneously, the connector and the power storage mechanism are electrically disconnected when the lid portion for the refueling port before the refueling operation is opened. Therefore, it is possible to reliably prevent overcharging and overdischarging of the power storage mechanism.

  In the control device according to the fourth aspect of the invention, in addition to the configuration of the second aspect of the invention, the vehicle is further provided with a connector lid that can be opened and closed outside the connector. The control means includes means for controlling the switching means so as to be in a shut-off state regardless of the open / closed state of the connector lid when the fuel filler lid is open.

  According to the fourth or eleventh invention, when the lid portion for the fuel filler opening is in an open state, the connector and the power storage mechanism are electrically disconnected regardless of the open / closed state of the connector lid portion. As a result, even if the operator opens the connector lid and then connects the power supply or electrical load outside the vehicle to the connector to perform charging / discharging work, the fuel filler lid is still open. The connector and the power storage mechanism are electrically disconnected. Therefore, even if the operator is distracted by the refueling operation, charging and discharging of the power storage mechanism is not performed, and overcharging and overdischarging of the power storage mechanism can be reliably prevented.

  In the control device according to the fifth aspect of the invention, in addition to the configuration of the second aspect of the invention, the control means controls the switching means so as to be in the connected state when the lid for the fuel filler is in the closed state. Means for. The control method according to the twelfth invention has the same requirements as the control device according to the fifth invention.

  According to the fifth or twelfth invention, the connector and the power storage mechanism are electrically connected when the fuel filler lid is closed and the fueling operation is not performed. As a result, when the connector and the power storage mechanism are electrically connected, the operator can concentrate on the charge / discharge work, so that overcharge and overdischarge of the power storage mechanism can be prevented.

  In the control device according to the sixth aspect of the invention, in addition to the configuration of the second aspect of the invention, the vehicle is further provided with a connector lid that can be opened and closed outside the connector. The control device further includes means for detecting the open / closed state of the connector lid. The control means includes means for controlling the switching means so as to be connected when the connector lid is in an open state, in addition to when the fuel filler lid is in a closed state. The control method according to the thirteenth aspect has the same requirements as the control device according to the sixth aspect.

  According to the sixth or twelfth invention, the connector and the power storage mechanism are electrically connected when the filler opening lid is in the closed state and the connector lid is in the open state. When the connector and the power storage mechanism are electrically connected, the operator can concentrate on the charging / discharging operation, so that overcharging and overdischarging of the power storage mechanism can be prevented. Furthermore, when the lid portion for the fuel filler opening is closed and the lid portion for the connector is open, the connector and the power storage mechanism are electrically connected. Therefore, when the connector lid is closed and charging / discharging operation is not performed, the connector and the power storage mechanism are electrically disconnected. Thereby, when charging / discharging work is not performed, for example, when the vehicle is traveling, it is possible to suppress leakage of current from the power storage mechanism via the switching means and the connector.

The control means includes means for controlling the switching means so as to enter the shut-off state when the state is estimated to stop. The control method according to the fourteenth invention has the same requirements as those of the control device according to the seventh invention.

  According to the seventh or fourteenth invention, the connector and the power storage mechanism are electrically disconnected when the vehicle is estimated to stop at a place where the fuel supply facility is provided. For this reason, a power supply and an electric load outside the vehicle are provided in a place where the fuel supply facility is provided, and even if charging / discharging work and refueling work are performed simultaneously, the vehicle is provided in a place where the fuel supply equipment is provided. Since the connector and the power storage mechanism are already electrically disconnected when it is estimated to stop, the power storage mechanism is not charged or discharged. Therefore, overcharging and overdischarging of the power storage mechanism can be reliably prevented.

  In the program according to the fifteenth aspect, a computer is caused to execute the control method according to any of the eighth to fourteenth aspects. A recording medium according to a sixteenth invention records a computer-readable program for causing a computer to execute the control method according to any of the eighth to fourteenth inventions.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

<First Embodiment>
With reference to FIG. 1, a hybrid vehicle 100 equipped with a control device according to the present embodiment will be described. In the present embodiment, the case where the control device according to the present invention is applied to a hybrid vehicle that can be charged from an AC power supply outside the vehicle will be described. However, the control device according to the present invention is applied to an electric load outside the vehicle. The present invention is also applicable to a hybrid vehicle that supplies power. The vehicle to which the control device according to the present invention can be applied is not limited to the hybrid vehicle 100 shown in FIG. 1, and may be a hybrid vehicle having another aspect.

  Hybrid vehicle 100 includes an engine 10, motor generators 20 </ b> A and 20 </ b> B, a power split mechanism 30, a drive shaft 40, drive wheels 50, a fuel tank 200, a battery 300, and an ECU 400.

  The engine 10 is connected to the fuel tank 200. The fuel tank 200 stores fuel for the engine 10 such as gasoline, ethanol (liquid fuel), propane gas (gaseous fuel), etc., and is supplied to the engine 10.

  The fuel tank 200 is connected via a fuel pipe 240 to a fuel supply port 230 to which fuel is supplied from an external fuel supply device (not shown). The fuel filler port 230 is covered with a fuel lid 210 provided on the vehicle outer side than the fuel filler port 230. The fuel lid 210 is controlled to be opened and closed by a fuel lid actuator 220 that is operated by a control signal from the ECU 400. Further, fuel lid actuator 220 detects the open / close state of fuel lid 210 and transmits a signal representing the detection result to ECU 400.

  Motor generator 20 </ b> A is coupled to engine 10 via power split mechanism 30 and mainly generates power. Motor generator 20 </ b> B has a rotating shaft connected to power split mechanism 30.

  Power split device 30 has first to third rotation shafts. The first rotating shaft is connected to engine 10, the second rotating shaft is connected to motor generator 20A, and the third rotating shaft is connected to motor generator 20B. A drive shaft 40 is connected to the third rotation shaft, and the second rotation shaft drives the drive shaft 40 to transmit power to the drive wheels 50.

  Power split device 30 plays a role of splitting power between engine 10 and motor generators 20A and 20B. That is, if the rotation of two of the three rotation shafts of the power split mechanism 30 is determined, the rotation of the remaining one rotation shaft is forcibly determined. Therefore, the vehicle speed is controlled by controlling the power generation amount of the motor generator 20A and driving the motor generator 20B while operating the engine 10 in the most efficient region, thereby realizing an overall energy efficient vehicle. Yes.

  Battery 300 is a secondary battery such as nickel hydride or lithium ion, for example, and is an assembled battery including a plurality of battery units B0 to Bn connected in series. Battery 300 is disposed at the rear of the vehicle.

  Between battery 300 and motor generators 20A and 20B, a boosting unit 302 and inverters 304A and 304B are provided.

  Boost unit 302 boosts the DC voltage received from battery 300 and supplies the boosted DC voltage to inverters 304A and 304B. Inverters 304A and 304B convert the supplied DC voltage into AC voltage and drive-control motor generators 20A and 20B when the engine is started. Further, after the engine is started, AC power generated by motor generators 20A and 20B is converted to DC by inverters 304A and 304B, and is converted to a voltage suitable for charging battery 300 by boosting unit 302 to charge battery 300. .

  Inverters 304A and 304B drive motor generators 20A and 20B. The motor generator 20B assists the engine 10 to drive the drive wheels 50. During braking, the motor generator performs a regenerative operation and converts the rotational energy of the wheels into electric energy. The obtained electrical energy is returned to the battery 300 via the inverters 304A and 304B and the boost unit 302.

  Further, the hybrid vehicle is provided with a connector 330 that is connected to an AC power supply outside the vehicle when the battery 300 is charged. Connector 330 is a charging connector for supplying electric power from an external AC power source to battery 300. Connector 330 is connected to main relay 340, and main relay 340 is connected to each neutral point of motor generators 20A and 20B via power lines 342A and 342B, respectively. The electric power supplied from the external AC power source to the connector 330 is supplied to the motor generators 20A and 20B via the main relay 340 and the power lines 342A and 342B, converted into direct current by the motor generators 20A and 20B, and then boosted. The voltage is stepped down by the unit 302 and the battery 300 is charged.

  The main relay 340 is ON / OFF controlled by the ECU 400, and switches the state between the connector 330 and the power lines 342A and 342B (that is, the battery 300) between an electrically connected state and an electrically disconnected state. When main relay 340 is turned on, connector 330 and power lines 342A and 342B (that is, battery 300) are electrically connected. When main relay 340 is turned off, connector 330 and power lines 342A and 342B are electrically disconnected.

  The connector 330 is covered with a connector lid 310 provided on the vehicle outer side than the connector 330. The connector lid 310 is controlled to be opened and closed by a connector lid actuator 320 that operates according to a control signal from the ECU 400. Furthermore, connector lid actuator 320 detects the open / close state of connector lid 310 and transmits a signal representing the detection result to ECU 400.

  Further, a system main relay (SMR) 350 is provided between the battery 300 and the boost unit 302. SMR 350 is controlled by ECU 400, and electrically connects battery 300 and boosting unit 302 when the hybrid system is activated.

  The ECU 400 is connected to a fuel lid opening / closing switch 402 and a connector lid opening / closing switch 404 via a harness or the like.

  The fuel lid opening / closing switch 402 is a switch for the driver to select whether the fuel lid 210 is opened or closed. When fuel lid on / off switch 402 is on, fuel lid on / off switch 402 transmits to ECU 400 a signal indicating that the driver has selected to open fuel lid 210. When fuel lid open / close switch 402 is off, fuel lid open / close switch 402 transmits a signal to ECU 400 indicating that the driver has selected to open fuel lid 210.

  The connector lid opening / closing switch 404 is a switch for the driver to select whether the connector lid 310 is to be opened or closed. When connector lid opening / closing switch 404 is on, connector lid opening / closing switch 404 transmits a signal to ECU 400 indicating that the driver has selected to open connector lid 310. When connector lid opening / closing switch 404 is turned off, connector lid opening / closing switch 404 transmits a signal to ECU 400 indicating that the driver has selected to open connector lid 310.

  ECU 400 controls the devices so that the vehicle is in a desired running state based on signals sent from each sensor, a map and a program stored in a ROM (Read Only Memory).

  With reference to FIG. 2, a functional block diagram of the control device according to the present embodiment will be described. As shown in FIG. 2, the control device includes an oil supply determination unit 410 and a main relay control unit 420.

  The fuel supply determination unit 410 determines whether or not there is a possibility of fuel supply based on a signal from at least one of the fuel lid open / close switch 402 and the fuel lid actuator 220.

  The main relay control unit 420 transmits a control signal corresponding to the determination result of the fuel supply determination unit 410 to the main relay 340.

  The control device according to the present embodiment having such functional blocks is read from a CPU (Central Processing Unit) and a memory and a memory included in the ECU 400 even with hardware mainly composed of a digital circuit or an analog circuit. It can also be realized by software mainly composed of programs executed by the CPU. In general, it is said that it is advantageous in terms of operation speed when realized by hardware, and advantageous in terms of design change when realized by software. Below, the case where a control apparatus is implement | achieved as software is demonstrated. Note that a recording medium on which such a program is recorded is also an embodiment of the present invention.

  With reference to FIG. 3, a control structure of a program executed by ECU 400 which is the control apparatus according to the present embodiment will be described. Note that this program is repeatedly executed at a predetermined cycle time.

  In step (hereinafter, step is abbreviated as S) 100, ECU 400 detects the state of fuel lid 210 based on a signal from at least one of fuel lid opening / closing switch 402 and fuel lid actuator 220.

  In S102, ECU 400 determines whether or not fuel lid 210 is in an open state. If it is in the open state (YES in S102), the process proceeds to S104. Otherwise (NO in S102), the process proceeds to S106.

  In S104, ECU 400 turns off main relay 340. In S106, ECU 400 turns on main relay 340.

  The operation of ECU 400 according to the present embodiment based on the above-described structure and flowchart will be described.

  When only the charging operation is performed, fuel lid 210 is in a closed state (NO in S102), so main relay 340 is turned on (S106), and connector 330 and battery 300 are electrically connected. Thus, when an external AC power source is connected to the connector 330, power is supplied from the AC power source to the battery 300, and the operator can concentrate on the charging operation, so that overcharging of the battery 300 can be prevented.

  When fuel lid 210 is opened for refueling during such a charging operation (YES in S102), main relay 340 is turned off even if connector lid 310 is open and charging is in progress (S104). ), The connector 330 and the battery 300 are electrically disconnected. Therefore, even if the worker starts the refueling operation while continuing the charging operation, power is not supplied to the battery 300 from the external AC power source. Thereby, even if the operator is more distracted by refueling work than charging work, overcharging of the battery 300 can be reliably prevented.

  As described above, according to the control device of the present embodiment, when the fuel lid is opened for refueling, the battery and the connector to which the external power supply is connected are electrically disconnected. Thereby, even if the operator performs the charging operation and the refueling operation at the same time, no electric power is supplied to the battery, so that overcharging of the battery can be reliably prevented.

  In the present embodiment, the case where the main relay 340 switches the electrical connection state between the connector 330 and the battery 300 has been described. For example, the same control as the main relay 340 is performed on the SMR 350. Thus, the SMR 350 may have the same function as the main relay 340.

  In the present embodiment, the case where main relay 340 is provided between connector 330 and motor generators 20A and 20B has been described. However, the place where main relay 340 is provided is not limited to this. For example, as shown in FIG. 4, the main relay 340 may be directly connected to the battery 300 via power lines 1342A and 1342B, and power from an external DC power supply may be directly supplied to the battery 300. In FIG. 4, the power lines 1342A and 1342B may be connected between the boosting unit 302 and the SMR 350. Even in such a connection, the SMR 350 can have the same function as the main relay 340.

The hybrid vehicle 2100 equipped with the control device according to the present embodiment is different from the configuration of the hybrid vehicle 100 according to the first embodiment described above in that the navigation device 2090 is included. The control structure of the executed program is different. The configuration other than these is the same as the configuration of hybrid vehicle 100 according to the first embodiment described above. The same reference numerals are assigned to the same components. Their functions are the same. Therefore, detailed description thereof will not be repeated here.

  With reference to FIG. 8, a hybrid vehicle 2100 equipped with the control apparatus according to the present embodiment will be described.

  Hybrid vehicle 2100 includes navigation device 2090 as described above. The navigation device 2090 calculates current traveling position information of the hybrid vehicle 2100 based on information received from a GPS (Global Positioning System) satellite. Navigation device 2090 transmits a signal representing the calculated traveling position information to ECU 400.

  With reference to FIG. 9, a control structure of a program executed by ECU 400 which is the control apparatus according to the present embodiment will be described. In the flowchart shown in FIG. 9, the same steps as those in the flowchart shown in FIG. 3 are given the same step numbers. The processing is the same for them. Therefore, detailed description thereof will not be repeated here.

  In S400, ECU 400 detects current traveling position information of hybrid vehicle 2100 based on the signal from navigation device 2090.

  In S402, ECU 400 determines whether or not hybrid vehicle 2100 is predicted to enter the gasoline station. For example, ECU 400 determines whether or not hybrid vehicle 2100 is predicted to enter the gasoline station by comparing the detected travel position information with the previously stored gasoline station position information. If it is predicted that a gasoline station will be entered (YES in S402), the process proceeds to S104. Otherwise (NO in S402), the process proceeds to S106.

  The operation of ECU 400 according to the present embodiment based on the above-described structure and flowchart will be described.

  If it is predicted that hybrid vehicle 2100 will enter the gasoline station for refueling (YES in S402), main relay 340 is turned off (S104), and connector 330 and battery 300 are electrically disconnected. As a result, the connector 330 and the battery 300 are already electrically disconnected even if the charging operation and the refueling operation are performed simultaneously at the gasoline station where the hybrid vehicle 2100 has stopped. Therefore, as in the first embodiment described above, overcharging of battery 300 can be reliably prevented.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
