Definitions
- the present invention relates to a hybrid vehicle that can switch between an EV mode that travels only by a motor without using an engine and an HV mode that travels by using both the engine and the motor.
- the EV mode usage ratio (the ratio of the HV mode and EV mode usage time) in which only the motor is used without using the engine is also increasing.
- a motor alone cannot produce a large output, and there are still situations where the HV mode using both the engine and the motor is used.
- Patent Documents 1 to 3 propose techniques related to increasing the usage ratio of the EV traveling mode.
- Patent document 1 is disclosing one technique which suppresses that acceleration performance is impaired in EV mode.
- the hybrid vehicle control device can travel in EV until the accelerator opening further increases by a predetermined amount dACC.
- the EV mode is switched to the HV mode.
- the EV mode can be maintained without suppressing the accelerator opening, and the acceleration performance in the EV mode is rarely impaired.
- Patent Document 2 discloses a technique for displaying an accelerator opening degree at which the EV mode is switched to the HV mode. The user can adjust the accelerator opening so as to maintain the EV based on the display.
- Patent Document 3 discloses a technique for increasing the usage rate of the EV mode by suppressing engine driving for warming up the engine and exhaust gas catalytic converter.
- the hybrid vehicle control device is programmed to switch to the HV mode when the output is insufficient with the motor alone or when the remaining battery level (SOC: State Of Charge) is below a predetermined lower limit. . In the latter case, power is generated by the driving force of the engine and the battery is charged.
- SOC State Of Charge
- the control device of the hybrid vehicle determines the driving force mainly according to the vehicle speed and the accelerator opening.
- this driving force is the driving force desired by the driver, it will be referred to as required torque. Accordingly, when the accelerator opening increases, the control device switches from the EV mode to the HV mode. A user who knows this empirically adjusts the accelerator opening so as not to switch to the HV mode as much as possible.
- the control device places a limit on the output of the battery.
- the control device determines the limit value of the battery output based on the remaining battery level (SOC: State Of Charge) and the battery temperature.
- the control device may limit the output of the motor.
- the control device determines the motor output limit value based on hardware requirements and the motor temperature.
- the above limit values are provided to prevent overheating, such as battery temperature and motor temperature.
- the control device provides an upper limit value (battery output upper limit value) for doubled output or a motor output upper limit value (motor output upper limit value) under the restrictions of the above limit values to prevent battery deterioration and improve fuel efficiency. ) As appropriate.
- the technology disclosed in this specification changes the battery output upper limit value and the motor output upper limit value according to the situation, and suppresses deterioration of the battery. Note that the technology disclosed in this specification can suppress the deterioration of the battery by changing the upper limit value of the required torque described later instead of the battery output upper limit value and the motor output upper limit value.
- the hybrid vehicle control device is programmed to switch to the HV mode when the required torque cannot be satisfied by the motor alone. Therefore, it is conceivable to increase the motor output upper limit value and increase the motor output range in order to increase the EV mode usage rate.
- the motor output upper limit value is increased, the battery output upper limit value is also increased, and the deterioration of the battery such as overheating of the battery is accelerated.
- the present specification provides a technique for suppressing battery deterioration in a situation where the usage rate of the EV mode is expected to increase.
- the novel hybrid vehicle disclosed in the present specification includes a control device capable of switching between an EV mode that travels using only a motor and an HV mode that travels using both an engine and a motor.
- the control device limits the use range of the battery in the EV mode when there is an EV mode execution request for the vehicle by external information input to the vehicle, compared to the EV mode when there is no execution request.
- the information input from the outside includes, for example, an operation of the EV switch by the driver, a signal from the navigation device, or a signal from the infrastructure.
- a suitable example of limiting the usage range of the battery is to limit the output power from the battery. That is, lowering the battery output upper limit value. Another example is to limit (lower) at least one of the battery output upper limit value, the upper limit value of the required torque calculated based on the accelerator opening and the vehicle speed of the driver, and the motor output upper limit value. .
- the control device may be programmed to limit the use range of the battery by increasing the engine start remaining amount threshold of the battery.
- the hybrid vehicle disclosed in this specification limits the battery usage range when the EV mode usage rate is expected to increase, thereby suppressing battery deterioration.
- EV mode may be further divided into multiple modes.
- One is a mode in which the hybrid system is controlled so that the usage rate of the EV mode increases, and is referred to as a CD mode in this specification.
- the control device automatically switches between the CD mode and the non-CD mode according to the vehicle running state.
- the first EV mode the case where there is no EV running execution request for the vehicle by external information input
- the second EV mode the case where there is a request
- the control device can switch between the CD mode and the non-CD mode.
- the control device can run the EV more than in the first EV mode. It is preferable to limit the use range of the battery inside.
- a system block diagram of a hybrid vehicle is shown.
- An example of a graph for determining the required torque is shown. It is a graph (relationship between accelerator opening and output) for explaining the difference between two EV modes. It is a graph which shows the example of the mode switching in a different vehicle speed. It is a figure explaining the difference of the transition from EV mode to HV mode, and the transition from HV mode to EV mode. It is a graph explaining EV / HV mode switching processing according to demand torque. It is a flowchart figure of EV mode switching process. It is a graph which shows mode switching (modification) in different vehicle speed.
- the hybrid vehicle 100 of the embodiment will be described with reference to the drawings.
- the hybrid vehicle 100 travels while automatically switching between an EV mode that travels using only the motor 12 and an HV mode that travels using both the motor 12 and the engine 19.
- an EV mode that travels using only the motor 12
- an HV mode that travels using both the motor 12 and the engine 19.
- there are two types of EV mode (a first EV mode and a second EV mode).
- the hybrid vehicle 100 includes two motors (a first motor 12a and a second motor 12b) and an engine 19 as drive sources.
- the output torques of the two motors 12 a and 12 b and the engine 19 are appropriately distributed / combined by the power distribution mechanism 14 and transmitted to the axle 15.
- the axle 15 is interlocked with the drive wheel 17 via a differential 16.
- the second motor 12b is driven together with the engine 19 (HV mode).
- the first motor 12a is mainly used as a starter and a generator.
- the first motor 12a is driven together with the second motor 12b by the power of the battery.
- driving forces are combined by the power distribution mechanism 14 and transmitted to the drive wheels 17 via the axle 15.
- a large driving force is not required, for example, when traveling at a constant speed, the engine 19 is stopped and the vehicle travels only with the second motor 12b (EV mode).
- the remaining capacity of the main battery 5 decreases, the engine 19 is started, and the torque of the engine 19 is distributed to the axle 15 and the first motor 12a by the power distribution mechanism 14. While driving the driving wheel 17 by the driving force of the engine 19, the first motor 12a is driven to generate electric power.
- the axle 15 is directly connected to the motors 12a and 12b, and the motors 12a and 12b are reversely driven from the output shaft side by the kinetic energy of the vehicle to generate electricity. That is, the hybrid vehicle 100 converts the kinetic energy of the vehicle into electric energy and charges the main battery 5 with the electric power.
- the first motor 12a also functions as a starter that starts the engine 19 when shifting from the EV mode to the HV mode.
- the power distribution mechanism 14 is a planetary gear, its sun gear is connected to the first motor 12 a, its planetary carrier is connected to the engine 19, and its ring gear is engaged with the axle 15.
- the second motor 12b is engaged with the axle 15 via another gear.
- the motors 12 a and 12 b and the engine 19 are controlled by the control device 4.
- control device 4 the hybrid vehicle 100 actually includes a large number of control devices provided for each function, and the large number of control devices cooperate to function as a single vehicle system.
- control device 4 the control devices are physically divided into a plurality of control devices, they are collectively referred to as “control device 4”.
- Electric power for driving the first motor 12a and the second motor 12b is supplied from the main battery 5.
- the output voltage of the main battery 5 is, for example, 300 [V].
- Main battery 5 is connected to first converter 8 via system main relay 7.
- the system main relay 7 is a switch that connects or disconnects the main battery 5 and the vehicle drive system.
- the system main relay 7 is switched by the control device 4.
- the first converter 8 boosts the voltage of the main battery 5 to a voltage suitable for driving the motor (for example, 600 [V]).
- the output of the first converter 8 is sent to the first inverter 9a and the second inverter 9b.
- the first inverter 9a converts the DC power output from the first converter 8 into AC power having a predetermined frequency and supplies it to the first motor 12a.
- the second inverter 9b converts the DC power output from the first converter 8 into AC power having a predetermined frequency and supplies it to the second motor 12b.
- the hybrid vehicle 100 can charge the main battery 5 with regenerative power.
- the output of the main battery 8 is also sent to the second converter 37.
- the second converter 37 is a step-down DCDC converter that steps down the output voltage (for example, 600 [V]) of the first converter 8 to a voltage (for example, 12 [V]) suitable for driving other electronic devices.
- the second converter 37 supplies power to a device (low power device) driven at a low voltage of 12 [V]. Examples of the low power device include a room light, a car audio, a car navigation 24, and the like.

That is, in a range where the accelerator opening is smaller than the switching opening Psw, the control device 4 determines that the target output commanded to the motor is the motor output upper limit Fout when the calculated target output Ftgt exceeds the motor output upper limit Fout. Limit to. In the example of FIG.

- EV mode 1 and EV mode 2 are switched by a mode selection switch 22 (see FIG. 1) provided in the driver's seat. That is, the EV mode 1 and the EV mode 2 are switched according to the user's intention.
- the EV mode 1 and the EV mode 2 can also be switched by a signal from the car navigation 24. For example, since economical driving is desired in an urban area, if the current position of the vehicle is an urban area, the car navigation 24 transmits a signal requesting to select the EV mode 2 to the control device 4. Based on the signal from the car navigation 24, the control device 4 switches from the EV mode 1 to the EV mode 2 if the state of another vehicle (for example, the SOC of the battery) permits.
- the state of another vehicle for example, the SOC of the battery
- FIG. 7 shows a flowchart of the EV mode switching process.
- the control device 4 first checks whether or not there is a request to continue EV travel (S2). In the case of the present embodiment, several “requests for continued EV travel” are assumed. One is a signal from the mode selection switch 22 provided in the driver's seat. Selection of the EV mode 1 by the driver corresponds to one of “EV travel continuation request”. The EV mode 2 selection signal from the navigation also corresponds to one of “EV travel continuation request”.
- the control device 4 selects EV mode 2 (S3) when there is a request to continue EV travel (S2: YES), and selects EV mode 1 (S13) otherwise.
- the control device 4 starts the torque-dependent engine start process described above (S14), and sets Fout1 as the motor output upper limit value in the EV mode (S15).
- the control device 4 stops the torque-dependent engine start process (S4), and sets Fout2 as the motor output upper limit value in the EV mode (S5).
- Fout2 ⁇ Fout1.
- the control device 4 After raising the motor output upper limit value, the control device 4 starts the engine (S8). The control device 4 repeats the process of FIG. 7 every predetermined control cycle.
- FIG. 8 shows the relationship between the accelerator opening P and the target output Ftgt in the modification.
- the vehicle speed Sp1
- dP2 ⁇ dP1. That is, when the accelerator opening reaches the motor output upper limit Fout2 at the first opening Pr1, the control device 4 increases the accelerator opening from the first opening Pr1 to the switching opening Psw2a to be switched to the HV mode.
- the first increment dP1 is set and the motor opening upper limit Fout2 is reached at the second opening Pr2 where the accelerator opening is larger than the first opening Pr1, the accelerator from the second opening Pr2 to the switching opening Psw2b
- a second increment dP2 smaller than the first increment dP1 is set as the opening increment.
- the EV mode 2 increases the switching opening degree Psw for shifting to the HV mode and lowers the motor output upper limit value Fmax as compared with the EV mode 1.
- the motor output upper limit value Fmax generally corresponds to the output upper limit value Wmax of the main battery 5. That is, lowering the motor output upper limit value from Fout1 to Fout2 leads to lowering the output upper limit value Wmax of the main battery 5. Therefore, in the EV mode 2, the output of the motor can be suppressed low, but the power consumption of the main battery 5 can also be suppressed. Therefore, the EV mode 2 has an advantage of suppressing deterioration of the main battery 5.
- the output upper limit value of the motor (or the output upper limit value of the battery) is increased so that a large driving force can be obtained.
- the motor output upper limit (or the battery output upper limit) is increased, the main battery 5 is likely to overheat, and the number of cases where the control device is prohibited from the EV mode increases. That is, increasing the motor output upper limit (or battery output upper limit) does not necessarily lead to an increase in the EV mode usage rate.
- a mode for lowering the motor output upper limit value is prepared for a user who wants to frequently use the EV mode, contrary to the prior art. The EV mode can be maintained for a long time by lowering the motor output upper limit value and suppressing the overheating of the main battery 5.
- the EV mode 1 (first EV mode) and the EV mode 2 (second EV mode) are switched by a signal from the mode selection switch 22 provided in the driver's seat or a signal from the car navigation 24.
- the mode switching may be performed not only by them but also by a signal from the infrastructure. For example, in the future, priority may be imposed on the EV mode in a specific area such as a central area of a large city. In such a case, mode switching may be performed by a signal from a communication device (that is, infrastructure) installed outside the vehicle.
- the control device 4 reduces the motor output upper limit value Fmax. As described above, when the motor output upper limit value Fmax is lowered, the output upper limit value Wmax of the main battery 5 is also lowered. Therefore, the control device 4 may lower the output upper limit value Wmax of the main battery 5 instead of lowering the motor output upper limit value Fmax. Also, by providing an upper limit value for the required torque and lowering the upper limit value, the output of the main battery 5 can be reduced, so that the same effect as in the embodiment, that is, the effect of suppressing deterioration of the main battery 5 can be obtained. Therefore, the control device 4 may lower the upper limit value of the required torque instead of lowering the motor output upper limit value Fmax.
- control device 4 cannot arbitrarily set the motor output upper limit value.
- the settable upper limit of the motor output upper limit is determined by the hardware requirements of the hybrid system and the motor temperature.
- the control device 4 determines the motor output upper limit value Fmax in accordance with the processing of the above embodiment within a settable range.
- the settable upper limit of the main battery output upper limit is determined by the remaining battery charge SOC and the battery temperature.
- the control device 4 determines the battery output upper limit value Wmax within a settable range.
- the control device 4 of the hybrid vehicle 100 has a CD mode (ChargepleDepleting mode: battery remaining amount priority consumption mode) and a CS mode (Charge Sustaining mode: battery remaining amount holding mode).
- a CD mode ChargepleDepleting mode: battery remaining amount priority consumption mode
- a CS mode Charge Sustaining mode: battery remaining amount holding mode.
- the CD mode is a mode that prioritizes the EV mode
- the CS mode is a mode that prioritizes the HV mode.
- a mode in which the battery level SOC is easily maintained at the target value by shifting to the HV mode will be referred to as a non-CD mode.
- the CD mode is generally a mode for controlling the hybrid system so that the usage rate of the EV mode increases.
- the control device 4 performs a process for completely prohibiting engine start, a process for providing a dead zone near the engine start threshold value of the accelerator, a process for expanding the use range of the main battery, and the like.
- the threshold value is set so that EV traveling is easily sustained.
- the CD mode and non-CD mode will be explained in detail.
- the CD mode is a mode in which the engine 19 is stopped and traveling by only the second motor 12b (that is, EV mode) is prioritized.
- the non-CD mode is a mode in which the engine 19 is driven, the first motor 12a is rotated by the driving force of the engine 19 to generate power, and the remaining SOC of the main battery 5 is maintained at a predetermined amount.
- the control device 4 automatically switches between the CD mode and the non-CD mode based on the remaining amount SOC of the main battery 5. Specifically, the control device 4 selects the CD mode if the remaining amount SOC is higher than a predetermined threshold SOC, and selects the non-CD mode if the remaining amount SOC is lower than the threshold SOC. In the non-CD mode, the control device 4 controls the engine 19 and the first motor 12a so that the remaining amount SOC maintains the threshold SOC.
- the control device 4 of the embodiment switches from the first EV mode to the second EV mode, and lowers the battery output upper limit value Wmax. Further, when the mode selection switch 22 is pressed while the CS mode is selected, the control device 4 switches to the CD mode and then shifts to the second EV mode.
- the technology disclosed in the present specification is based on a case where there is an EV travel execution request for a vehicle by information input from the outside to the vehicle (for example, a switch operation by a driver, a signal from navigation, or a signal from infrastructure). It should be noted that the present invention can also be applied to a hybrid vehicle in which engine starting is completely prohibited during EV traveling.
- the control device of the embodiment is programmed to be switchable between the following two EV modes (a first EV mode and a second EV mode).
- first EV mode the control device sets the motor output upper limit value Fmax in the EV mode to the first output upper limit value Fout1, and sets the switching accelerator opening that switches from the EV mode to the HV mode to the first opening.
- second EV mode the control device sets the motor output upper limit value Fmax in the EV mode to the second output upper limit value Fout2 lower than the first output upper limit value Fout1, and sets the switching accelerator opening degree for switching from the EV mode to the HV mode.
- the second switching opening is set larger than the first switching opening.
- the control device may be programmed to switch between the following two EV modes. In the first EV mode, the control device sets the battery output upper limit value Wmax in the EV mode to the first output upper limit value Wout1, and sets the switching accelerator opening that switches from the EV mode to the HV mode to the first opening.
- the control device sets the battery output upper limit value Wmax in the EV mode to the second output upper limit value Wout2 lower than the first output upper limit value Wout1, and sets the switching accelerator opening degree for switching from the EV mode to the HV mode.
- the second switching opening is set larger than the first switching opening.
- the motor output upper limit value Fmax is changed from the second output upper limit value Fout2 to the first output upper limit value before starting the engine. It is preferable to raise to Fout1. If the motor output upper limit value is kept low, the motor driving force required to start the engine may be insufficient. The engine can be reliably started by raising the output upper limit value of the motor.
- the control device 4 may raise the battery output upper limit value Wmax instead of the motor output upper limit value Fmax prior to starting the engine.
- the technology disclosed in this specification can also be applied to a so-called plug-in hybrid vehicle that can be charged from an external power source.
