- FIG. 3 is a flow chart showing the process performed in the HV-ECU 21 at predetermined time intervals.
- the HV—ECU 21 determines the state of charge SOC of the battery 19 (State
- step S001 It is checked whether or not the vehicle is under a predetermined assist permission condition such that If Charge is a predetermined value or more, MG12 is a predetermined temperature or less, and the vehicle speed is a predetermined value or more (step S001).
- the HV-ECU 21 checks whether or not the driver has made an acceleration request (Step S002). For example, if the vehicle is equipped with an accelerator opening sensor, the accelerator pedal is depressed from the previous time, and if the accelerator opening is increasing, the acceleration judgment flag is set, and the acceleration is returned when it is returned. When the judgment flag is cleared, processing is performed
- the HV-ECU 21 determines whether the MG assist condition is satisfied, based on the results of the step S 001 and the step S 002 (step S 003).
- the state of charge SOC of the battery 19 is equal to or less than a predetermined value, it is determined that the MG assist is unnecessary if the driver does not request acceleration or if the vehicle is not traveling.
- MG assist torque is set to 0 (step S005).
- the HV-ECU 21 confirms whether or not the kick down condition is satisfied (step S 004).
- the kick down we say here is the run It is to automatically shift down control the transmission of the transmission 13 to the low speed gear for acceleration in a row. For example, it is determined that a kickdown request has been made when the accelerator opening ⁇ or the change ⁇ ⁇ of the accelerator opening exceeds a predetermined threshold ⁇ .
- the threshold ⁇ may be a fixed value or dynamically according to the traveling state of the vehicle.
- the HV-ECU 21 obtains an increase amount of the driver request torque according to the vehicle speed and the opening degree, and calculates this as the gear of the MG gears 61, 64.
- the value divided by the ratio is used as it is as the MG assist torque (step S 007).
- the HV-ECU 21 calculates the driver request torque in consideration of the torque which increases due to the kick-down (the driver calculated from the vehicle speed and the accelerator opening angle A value obtained by dividing the required torque by the gear ratio of the required gear) by the gear ratio of the MG gear 61, 64 is set as the MG assist torque (step S006). At this time, it is assumed that the HV-ECU 21 does not actually shift (downshift).
- the HV-ECU 21 performs the limiting process of the MG assist torque calculated in the above step S 006 or S 007 based on the items such as SOC direct, MG temperature, MG maximum output and the like (step S 008).
- the HV-ECU 21 confirms whether or not the driver request torque can be satisfied with the thus-calculated 'restricted MG assist torque (step S 009).
- the HV-ECU 21 determines the MG assist torque as the command torque, and instructs the MG-ECU (step S 011).
- the MG assist torque can not meet the demand requested by the driver! /,
- the HV-ECU 21 adds the difference between the increase amount of the driver demand torque and the MG assist torque to the engine demand torque.
- the MG assist torque and the engine request torque are determined as the command torque, and the MG-ECU and the EG-ECU are commanded (step S011).
- step S001 of FIG. 3 the state of charge of the battery 19 is below the predetermined value. If it is determined that the process is not possible, the process proceeds to the flowchart of FIG. 9, and if the driver makes an acceleration request in step S101 and the kickdown condition is satisfied in step S102, the process proceeds to step S103. Implement control to shift down the transmission of transmission 13 to the low gear automatically.
- the driving power can be increased by performing kick-down control to meet the driver's acceleration demand.
- the solid line in FIG. 6 represents the traveling performance curve (EG torque only) of each gear from lst to 3rd, and the broken line in FIG. 6 represents the traveling performance curve (EG torque + with torque assist by MG) Represents MG torque)!
- the point C' is the performance of the 2nd speed (2nd). Because it is above the curve (EG torque only), the conventional drive source control device kicks down to 1st. Even if the 1st kickdown is performed, the C 'point is above the 1st speed (1st) performance curve (EG torque only), so the driving force is insufficient.
- the drive source control device according to the present invention although kickdown is not performed, the additional torque of the engine is necessary because the torque increase required by the MG 12 is large because the torque increase request width is large. Therefore, in this case, the present invention is advantageous in that the kick-down can be eliminated (including time loss associated with kick-down, fuel consumption and exhaust gas suppression) and the additional engine torque can be reduced (see FIG. 5).
- MG such as MG temperature and remaining battery capacity can normally function
- MG's response to the driver's acceleration request is made first by MG, so engine torque increase, fuel injection increase, etc.
- MG In addition to being able to avoid an increase in exhaust gas, it is possible to improve responsiveness to driver requests (make kickdown unnecessary) and achieve cancellation of driving force interruption (torque loss) due to shifting.
- the engine S and the motor S are the power S described with an example of the hybrid vehicle having a configuration in which the driving force output by the MG is transmitted to the differential 14.
- the present invention is also applicable to other vehicles having a parallel relationship and driving the vehicle.
- control of the HV-ECU 21 may be performed as shown in the flowchart of FIG.
- steps S001 to S009 are the same as steps S001 to S009 in the flowchart of FIG.
- step S 009 when the torque requested by the driver can not be obtained by the MG assist torque, the HV-ECU 21 performs control to shift down the shift of the transmission 13 automatically to the low speed gear in step S 210. Therefore, even if the additional torque by the MG12 causes a torque shortage, it is possible to increase the noise power by performing the kick-down control to meet the driver's acceleration demand.
