Description

  The present invention relates to a hybrid vehicle and an information output method.

  Conventionally, when the ignition switch is turned off, the engine is stopped when the battery charge amount is greater than or equal to the set value, and when the battery charge amount is less than the set value, the engine continues to be driven if the shift position is in the P range. Thus, an automobile has been proposed in which the battery is charged and the engine is stopped unless the shift position is in the P range (see, for example, Patent Document 1). In this automobile, if the battery charge amount is less than the set value when the ignition switch is turned off and the shift position is not in the P range, the battery charge amount is insufficient or the shift position is not in the P range. Is displayed on the display device, so that the driver can recognize and respond to the fact that the charge amount of the battery is insufficient.

A battery 50 that exchanges power, a battery electronic control unit (hereinafter referred to as a battery ECU) 52 that manages the battery 50, and a hybrid electronic control unit 70 that controls the entire vehicle are provided.

  The battery ECU 52 is configured as a microprocessor centered on a CPU (not shown), and includes a ROM, a RAM, an input / output port, and a communication port in addition to the CPU. The battery ECU 52 receives signals necessary for managing the battery 50, for example, an inter-terminal voltage Vb from the voltage sensor 51 a installed between the terminals of the battery 50, and a power line 54 connected to the output terminal of the battery 50. The charging / discharging current Ib from the attached current sensor 51b, the battery temperature Tb from the temperature sensor 51c attached to the battery 50, and the like are input. Output to the control unit 70. Further, the battery ECU 52 is a ratio of the amount of stored electricity stored in the battery 50 based on the integrated value of the charge / discharge current Ib detected by the current sensor 51b in order to manage the battery 50 to the total capacity (storage capacity). The storage ratio SOC is calculated, and the input / output limits Win and Wout, which are the maximum allowable power that may charge / discharge the battery 50, are calculated based on the calculated storage ratio SOC and the battery temperature Tb. The input / output limits Win and Wout of the battery 50 are set to the basic values of the input / output limits Win and Wout based on the battery temperature Tb, and the output limiting correction coefficient and the input limiting limit are set based on the storage ratio SOC of the battery 50. It can be set by setting a correction coefficient and multiplying the basic value of the set input / output limits Win and Wout by the correction coefficient.

  The hybrid electronic control unit 70 is configured as a microprocessor centered on the CPU 72, and in addition to the CPU 72, a ROM 74 for storing processing programs, a RAM 76 for temporarily storing data, an input / output port and communication not shown. And a port. The hybrid electronic control unit 70 includes an ignition signal from the ignition switch 80, a shift position SP from the shift position sensor 82 that detects the operation position of the shift lever, and an accelerator pedal position sensor 84 that detects the amount of depression of the accelerator pedal.

It is output via. As described above, the hybrid electronic control unit 70 is connected to the engine ECU 24, the motor ECU 40, and the battery ECU 52 via the communication port, and exchanges various control signals and data with the engine ECU 24, the motor ECU 40, and the battery ECU 52. ing. In the hybrid vehicle 20 of the embodiment, the shift position SP detected by the shift position sensor 82 includes a parking position (P position), a neutral position (N position), a drive position (D position), and a reverse position (R position). and so on.

  The hybrid vehicle 20 of the embodiment configured in this way calculates the required torque to be output to the drive shaft 32 based on the accelerator opening Acc and the vehicle speed V corresponding to the amount of depression of the accelerator pedal 83 by the driver. The operation of the engine 22, the motor MG1, and the motor MG2 is controlled so that the required power corresponding to the torque is output to the drive shaft 32. As the operation control of the engine 22, the motor MG1, and the motor MG2, the operation of the engine 22 is controlled so that power corresponding to the required power is output from the engine 22, and all of the power output from the engine 22 is transmitted to the planetary gear 30 and the motor MG1. And the motor MG2 convert the torque and output to the drive shaft 32. The torque conversion operation mode for driving and controlling the motor MG1 and the motor MG2 and the power suitable for the sum of the required power and the power required for charging and discharging the battery 50 are obtained. The operation of the engine 22 is controlled so as to be output from the engine 22, and all or a part of the power output from the engine 22 with charging / discharging of the battery 50 is converted by the planetary gear 30, the motor MG1, and the motor MG2. Accordingly, the required power is output to the drive shaft 32. Charge-discharge drive mode for driving and controlling the motor MG1 and the motor MG2, there is a motor operation mode in which operation control to output a power commensurate to stop the operation of the engine 22 to the required power from the motor MG2 to the drive shaft 32. Both the torque conversion operation mode and the charge / discharge operation mode are modes in which the engine 22 and the motors MG1, MG2 are controlled so that the required power is output to the drive shaft 32 with the operation of the engine 22. Can be considered as an engine operation mode.

  Next, the operation of the hybrid vehicle 20 of the embodiment thus configured, particularly the operation of displaying information on the display 89 and outputting a warning sound from the speaker 90 when the shift position is the N position will be described. FIG. 2 is a flowchart showing an example of an N-position information output control routine executed by the hybrid electronic control unit 70. This routine is repeatedly executed every predetermined time (for example, every several msec) when the shift position SP is the N position. In the hybrid vehicle 20 of the embodiment, when the shift position SP is the N position, the inverters 41 and 42 are shut off (all the switching elements of the inverters 41 and 42 are turned off).

  When the N-position information output control routine is executed, the CPU 72 of the hybrid electronic control unit 70 first inputs the vehicle speed V from the vehicle speed sensor 88 and the storage ratio SOC of the battery 50 (step S100). Here, the storage ratio SOC of the battery 50 is input from the battery 50 through communication, which is calculated based on the integrated value of the charge / discharge current Ib detected by the current sensor 51b in order to manage the battery 50. .

  When the data is input in this way, the input storage ratio SOC of the battery 50 is compared with a predetermined threshold value Sref (step S110). Here, the threshold value Sref is used to determine whether or not the storage ratio SOC of the battery 50 is sufficiently low (whether it is better to charge the battery 50). An upper limit of the power storage ratio range that should be requested to charge the battery 50 to suppress it can be used, for example, 25% or 30% can be used. When the storage ratio SOC of the battery 50 is greater than or equal to the threshold value Sref, information indicating the storage ratio SOC of the battery 50 (hereinafter referred to as storage ratio information) is lit on the display 89 (step S120), and this routine ends. The state of the display 89 at this time is shown in FIG. In the example of FIG. 3, the power storage ratio information is displayed as an image.

  When the storage ratio SOC of the battery 50 is less than the threshold value Sref in step S110, the vehicle speed V is compared with a predetermined threshold value Vref (step S130). Here, the threshold value Vref is used for determining whether or not the vehicle is running, and for example, 3 km / h, 5 km / h, or the like can be used.

  When the vehicle speed V is less than or equal to the threshold value Vref, it is determined that the vehicle is not traveling, and information that prompts a change of the shift position SP to the P position is displayed on the display 89 while blinking the storage ratio information (hereinafter referred to as shift change request information). Is displayed, a warning sound is output from the speaker 90 (step S140), and this routine is terminated. The state of the display 89 at this time is shown in FIG. In the example of FIG. 4, the power storage ratio information and the shift change request information are displayed as images. In this case, it is possible to notify the driver that the storage ratio SOC of the battery 50 is decreasing by blinking the storage ratio information on the display 89 or outputting a warning sound from the speaker 90. Further, by displaying the shift change request information on the display 89, the driver can be prompted to shift the shift position SP to the P position. When the driver shifts the shift position SP to the P position, the gates of the inverters 41 and 42 may be released. Therefore, the motor MG1 is locked with the driving wheels 63a and 63b locked by a parking lock mechanism (not shown). The motor 22 is motored to start the motor 22, and the power from the engine 22 is used to generate power by the motor MG 1 to charge the battery 50 with the power. Thereby, the overdischarge of the battery 50 can be suppressed.

  When the vehicle speed V is higher than the threshold value Vref, it is determined that the vehicle is running, the storage ratio information is blinked on the display 89 and a warning sound is output from the speaker 90 (step S150), and this routine is terminated. The state of the display 89 at this time is shown in FIG. In the example of FIG. 5, the power storage ratio information is displayed as an image. In this case, it is possible to notify the driver that the storage ratio SOC of the battery 50 is decreasing by blinking the storage ratio information on the display 89 or outputting a warning sound from the speaker 90. Further, by not displaying the shift change request information on the display 89, the shift change request information is displayed on the display 89 when the shift position SP is traveling at the N position (inertia traveling), and the driver is confused. , The situation can be prevented from occurring. In this case, if the vehicle speed V subsequently decreases to the threshold value Vref or less, it is determined in step S130 that the vehicle speed V is equal to or less than the threshold value Vref, and the storage ratio information blinks on the display 89 and a warning is given from the speaker 90. In addition to outputting sound, shift change request information is displayed on the display 89.

  According to the hybrid vehicle 20 of the embodiment described above, when the shift position SP is the N position and the storage rate SOC of the battery 50 is less than the threshold value Sref, the storage rate information is displayed on the display 89 when the vehicle speed V is equal to or less than the threshold value Vref. When the vehicle speed V is higher than the threshold value Vref, the storage ratio information is flashed on the display 89 and the warning sound is output from the speaker 90 when the vehicle speed V is higher than the threshold value Vref. In the former case, it is possible to notify the driver that the storage ratio SOC of the battery 50 is decreasing, and to prompt the driver to shift the shift position SP to the P position. In this case, it is determined that the storage rate SOC of the battery 50 is decreasing. It is possible to inform the user, the shift change request information can be made to become confused by the driver is displayed, situation does not occur during travel.

  In the hybrid vehicle 20 of the embodiment, the power from the motor MG2 is output to the drive shaft 32 connected to the drive wheels 63a and 63b. However, as illustrated in the hybrid vehicle 120 of the modified example of FIG. The power from MG2 may be output to an axle (an axle connected to wheels 64a and 64b in FIG. 6) different from an axle (an axle connected to driving wheels 63a and 63b) to which driving shaft 32 is connected. .

  In the hybrid vehicle 20 of the embodiment, the power from the engine 22 is output to the drive shaft 32 connected to the drive wheels 63a and 63b via the planetary gear 30, and the power from the motor MG2 is output to the drive shaft 32. However, as illustrated in the hybrid vehicle 220 of the modified example of FIG. 7, the motor MG1 for power generation is connected to the engine 22 and the motor MG2 is connected to the drive wheels 63a and 63b to drive the motors MG1 and MG2. The battery 50 may be connected to the inverters 41 and 42.

  Moreover, it is not limited to the form of such a hybrid vehicle, It is good also as what is used as a form of the information output method in a hybrid vehicle.
