The engine 22 is an internal combustion engine that outputs power by hydrocarbon fuel such as gasoline or light oil, and is transmitted through an engine electronic control unit (hereinafter referred to as an engine ECU) 24 that receives signals from various sensors that detect the operating state of the engine 22. , to receive operation control such as fuel injection control, ignition control, and intake air volume adjustment control. The engine ECU 24 communicates with the electronic control unit 70 for hybrid power, and controls the operation of the engine 22 through the control signal from the electronic control unit 70 for hybrid power. state-related data.

The power distribution integrated mechanism 30 has a sun gear 31 of an external gear, a ring gear 32 of an internal gear coaxially arranged with the sun gear 31, a plurality of pinion gears 33 meshing with the sun gear 31 and the ring gear 32, Together with the carrier 34 holding the plurality of pinion gears 33 for free rotation and revolution, the sun gear 31 , the ring gear 32 and the carrier 34 as rotation elements, constitute a planetary gear device that performs a differential action. In the integrated power distribution mechanism 30, the planetary gear carrier 34 is connected to the crankshaft 26 of the engine 22, the sun gear 31 is connected to the motor MG1, and the reduction gear 35 is connected to the ring gear 32 through the ring gear shaft 32a. When the motor MG1 functions as a generator , the power input from the planetary gear carrier 34 from the engine 22 is distributed to the sun gear 31 side and the ring gear 32 side according to its gear ratio, and when the motor MG1 functions as a motor, the power input from the planetary gear carrier 34 from the engine 22 and the power input from the sun gear 31 and from the motor MG1 are integrated and then output to the ring gear 32 side. The power output to the ring gear 32 starts from the ring gear 32, passes through the gear mechanism 60 and the differential gear 62, and is finally output to the drive wheels 63a, 63b of the vehicle.

Either one of the motor MG1 and the motor MG2 has a known synchronous generator-motor structure that can be driven as a generator or as a motor, and exchanges electric power with the battery 50 through inverters 41 and 42 . Power line 54 connecting inverters 41, 42 and battery 50 is composed of a positive bus bar and a negative bus bar shared by inverters 41, 42, and electric power generated by one of motors MG1, MG2 can be consumed by the other motor. Therefore, the battery 50 is charged and discharged according to the electric power generated by either of the motors MG1 and MG2 or the electric power shortage. In addition, the storage battery 50 will not be charged or discharged if the electric power balance is achieved by the motors MG1 and MG2. Each of the motors MG1 and MG2 is driven and controlled by a motor electronic control unit (hereinafter referred to as a motor ECU) 40 . Signals necessary for driving and controlling the motors MG1 and MG2 are input to the motor ECU 40, for example, signals from the rotational position detection sensors 43 and 44 for detecting the rotational positions of the rotors of the motors MG1 and MG2 or signals detected by an unillustrated current sensor. The motor ECU 40 outputs switching control signals to the inverters 41 and 42 for the phase currents and the like applied to the motors MG1 and MG2. The motor ECU40 communicates with the electronic control unit 70 for hybrid power, drives and controls the motors MG1 and MG2 according to the control signal from the electronic control unit 70 for hybrid power, and at the same time, transfers the data related to the operating states of the motors MG1 and MG2 It is output to the electronic control unit 70 for hybrid power.

The battery 50 is managed by a battery electronic control unit (hereinafter referred to as battery ECU) 52 . The necessary signals for managing the storage battery 50 are, for example, the inter-terminal voltage Vb from the voltage sensor 51a provided between the terminals of the storage battery 50, the charging and discharging current Ib from the current sensor 51b connected to the output terminal of the storage battery 50, and the The battery temperature Tb and the like from the temperature sensor 51c on the battery 50 are input to the battery ECU 52, and data related to the state of the battery 50 is output to the hybrid electronic control unit 70 through information transmission as needed. In addition, in order to manage the battery 50, the battery ECU 52 also calculates a state of charge (SOC) based on the integrated value of the charging and discharging current Ib detected by the current sensor 51b.

The hybrid electronic control unit 70 is composed of a microprocessor centered on a CPU 72. In addition to the CPU 72, it also has a ROM 74 for storing processing programs, a RAM 76 for temporarily storing data, and unshown input and output ports and communication ports. The ignition signal from the ignition switch 80, the shift position SP from the shift position sensor 82 that detects the operating position of the shift lever 81, and the accelerator pedal opening degree from the accelerator pedal position sensor 84 that detects the depression amount of the accelerator pedal 83 Acc, brake pedal position BP from brake pedal position sensor 86 that detects the depression amount of brake pedal 85 , and vehicle speed V from vehicle speed sensor 88 are input to hybrid electronic control unit 70 through the input port. As mentioned above, the hybrid electronic control unit 70 is connected to the engine ECU 24 , motor ECU 40 , and battery ECU 52 through communication ports, and exchanges various control signals or data with the engine ECU 24 , motor ECU 40 , and battery ECU 52 .

The hybrid vehicle 20 of this embodiment configured in this way calculates the required torque to be output to the ring gear shaft 32a as the drive shaft based on the accelerator pedal opening Acc corresponding to the driver's depression amount of the accelerator pedal 83 and the vehicle speed V. , the engine 22 and the motors MG1 and MG2 are controlled so as to output the requested power corresponding to the requested torque to the ring gear shaft 32a. As the operation control of the engine 22 and the motor MG1 and the motor MG2, there is: while the engine 22 is controlled in such a manner that the power commensurate with the required power is output from the engine 22, all the power output from the engine 22 passes through the power distribution and integration mechanism 30 and The motor MG1 and the motor MG2 perform torque conversion, and drive and control the torque conversion operation mode of the motor MG1 and the motor MG2 in the form of output to the ring gear shaft 32a; or the power commensurate with the sum of the required power and the electric power required for charging and discharging the battery 50 While operating and controlling the engine 22 so as to be output from the engine 22, all or a part of the power output from the engine 22 is controlled by the torque generated by the power distribution and integration mechanism 30 and the motors MG1 and MG2 as the battery 50 is charged and discharged. Convert, drive and control the charging and discharging operation mode of the motor MG1 and the motor MG2 in a manner that requires power to be output to the ring gear shaft 32a; stop the operation of the engine 22, and output the power commensurate with the required power from the motor MG2 to the ring gear shaft 32a The motor operation mode of the mode operation control, etc.

Next, the operation of the hybrid vehicle 20 according to the embodiment configured in this way, especially the operation at the time of driving control based on the output management of the battery 50 will be described. FIG. 2 is a flow chart showing an example of a drive control routine executed by the hybrid electronic control unit 70 of the embodiment, and FIG. A flowchart of an example of an output management routine executed by the ECU 52 . Both routines are repeatedly executed at predetermined intervals (for example, at intervals of 8 msec). Hereinafter, first, the drive control will be described, and then management of the output limit Wout of the storage battery 50 used in the drive control will be described.

When executing the drive control routine, the CPU 72 of the electronic control unit 70 for hybrid power first performs an operation on the accelerator pedal opening Acc from the accelerator pedal position sensor 84, the vehicle speed V from the vehicle speed sensor 88, the rotation speeds Nm1 of the motors MG1, MG2, A process of inputting data necessary for control such as Nm2, the rotational speed Ne of the engine 22, and the output limit Wout (step S100). Here, the rotational speeds Nm1 and Nm2 of the motors MG1 and MG2 are calculated from the rotational positions of the rotors of the motors MG1 and MG2 detected by the rotational position detection sensors 43 and 44 and are input from the motor ECU 40 through communication. The rotation speed Ne of the engine 22 is detected by a crank position sensor (not shown) attached to the engine 22 , and the obtained rotation speed Ne is transmitted and input from the engine ECU 24 by communication. The output limit Wout is input by the output limit Wout which was set by the output management routine illustrated in FIG. 3 by communication from the battery ECU52.

After the data is input in this way, the required torque Tr ^* to be output to the ring gear shaft 32a as the drive shaft connected to the drive wheels 63a and 63b as the torque required by the vehicle is set according to the input accelerator pedal opening Acc and the vehicle speed V, and the required power Pr ^* that should be output by the engine 22 (step S110). Requested torque Tr ^* In the embodiment, the relationship between accelerator pedal opening Acc, vehicle speed V, and requested torque Tr ^* is set in advance, stored in ROM 74 as a table for requesting torque setting, and accelerator pedal opening Acc and vehicle speed V are given. , derive and set the requested torque Tr ^* corresponding to the memorized graph. FIG. 4 shows an example of a map for request torque setting. The required power Pe ^* can be calculated by multiplying the set required torque Tr ^* by the rotational speed Nr of the ring gear shaft 32a, and adding the sum of the charge and discharge required amount Pb ^* of the battery 50 and the loss. The rotational speed Nr of the ring gear shaft 32a is obtained by multiplying the vehicle speed V by the conversion coefficient k, and can be obtained by dividing the rotational speed Nm2 of the motor MG2 by the gear ratio Gr of the reduction gear 35 . The required charge and discharge amount Pb ^* can be set by the state of charge (SOC) of the battery 50, the accelerator pedal opening degree Acc, and the like.

After setting the required torque Tr ^* and the required power Pe ^* , the set required power Pe ^* is compared with the threshold value Pref (step S120). Here, the threshold value Pref is a range for setting the motor operation mode in which the engine 22 is stopped and only the power is output from the motor MG2, and it can be set by the performance of the motor MG2 and the capacity of the battery 50.

When the required power Pe ^* is greater than the threshold value Pref, it is determined whether or not the engine 22 is running (step S130). Then, when the engine 22 is running, it is determined whether the accelerator opening Acc is larger than the threshold Aref (step S140). The excess output request flag Fout is set to a value of 1 (step S150). Here, the threshold Aref is also a setting for judging whether or not an output exceeding the rated output is requested from the storage battery 50, and can be set to, for example, 70% or 80%. The output limit Wout of the storage battery 50 when the excess output request flag Fout is set to a value of 1 will be described below using the routine shown in FIG. 3 . Also, when the accelerator opening Acc is equal to or less than the threshold value Aref, it is not necessary to request an output exceeding the rated output from the battery 50 , so the value 1 is not set to the excess output request flag Fout.

Next, the target rotation speed ^{Ne* and} the target torque Te ^* of the engine 22 are set based on the set required power Pe* (step S160). In this setting, when the required torque Tr ^* is set in the required power Pe ^* , the target rotational speed Ne ^* and the target torque Te ^* are set based on the operation line for effectively operating the engine 22 and the required power Pe ^* . FIG. 5 shows an example of an operation line of the engine 22 and a situation in which the target rotation speed Ne ^* and the target torque Te ^* are set. As shown in the figure, the target rotation speed Ne ^* and target torque Te ^* can be obtained from the intersection of the operation line and the curve where the required power Pe ^* (Ne ^* ×Te ^* ) is a constant.

Next, the target rotational speed Nm1* ^of the motor MG1 is calculated by the following equation (1) using the set target rotational speed Ne ^* , the rotational speed Nr (Nm2/Gr) of the ring gear shaft 32a, and the gear ratio ρ of the power distribution integrated mechanism 30 , and at the same time, according to the calculated target rotation speed Nm1 ^* and the current rotation speed Nm1, the torque command Tm1 ^* of the motor MG1 is calculated by formula (2) (step S170). Here, Equation (1) is a dynamic relational expression with respect to the rotation elements of the power distribution and integration mechanism 30 . FIG. 6 shows a nomographic diagram of the dynamic relationship between the rotation speed and torque among the rotation elements of the power distribution and integration mechanism 30 . In the figure, the S axis on the left shows the rotation speed of the sun gear 31 as the rotation speed Nm1 of the motor MG1, the C axis shows the rotation speed of the planetary gear carrier 34 as the rotation speed Ne of the engine 22, and the R axis shows the rotation speed Nm2 of the motor MG2 multiplied by The rotation speed Nr of the ring gear 32 at the gear ratio Gr of the reduction gear 35 . Equation (1) can be easily derived using this collinear diagram. In addition, the two thick-line arrows on the R-axis indicate that, at the operating points of the target rotational speed Ne ^* and the target torque Te ^* , when the engine 22 is normally operated, the torque Te ^* output from the engine 22 is transmitted to the ring gear shaft 32a. torque, and the torque Tm2 output from the motor MG2 ^* is the torque acting on the ring gear shaft 32a through the reduction gear 35. In addition, Equation (2) is a relational expression in the feedback control for the target rotational speed Nm1 ^* rotating electric machine MG1. In Equation (2), "k1" in the second item on the right is the gain of the proportional item, and "k1" in the third item on the right is the gain of the proportional item. k2" is the gain of the integral term.

After calculating the target rotation speed Nm1 ^* and the torque command ^{Tm1 *} of the motor MG1 in this way, the power consumption of the motor MC1 ( The deviation of the generated electric power) is divided by the rotational speed Nm2 of the motor MG2, and the torque limit Tmax as the upper limit of the torque that can be output from the motor MG2 is calculated by the following equation (3) (step S180), and at the same time, the required torque Tr ^* and the torque The command Tm1 ^* and the gear ratio ρ of the power distribution integrated mechanism 30 are used to calculate the temporary motor torque Tm2tmp as the torque to be output from the motor MG2 by the formula (4) (step S190), and compare the calculated torque limit Tmax with the temporary motor torque Tm2tmp , and the smaller one is set as the torque command Tm2 ^* of the motor MG2 (step S200). By setting the torque command Tm2 ^* of the motor MG2 in this way, the required torque Tr ^* output to the ring gear shaft 32a as the drive shaft can be set as a limited torque within the range of the output limit Wout of the battery 50. In addition, Equation (4) can be easily derived from the aforementioned collinear diagram of FIG. 6 .

After setting the target rotation speed Ne ^* and the target torque Te ^* of the engine 22, the target rotation speed Nm1 ^* and the torque command Tm1* of the motor MG1, and the torque command Tm2 ^* of the motor MG2 in this way, the target rotation speed ^{Ne* and} the target torque Te of the engine 22 are set to ^* is transmitted to the engine ECU24, and at the same time, the target rotational speed Nm1 ^* and the torque command Tm1 ^* of the motor MG1 and the torque command Tm2 ^* of the motor MG2 are transmitted to the motor ECU40 (step S210), and the drive control routine ends. The engine ECU 24 receiving the target rotation speed Ne ^* and the target torque Te ^* performs fuel injection control, ignition control, etc. in the engine 22 so that the engine 22 operates at the operating point indicated by the target rotation speed Ne ^* and the target torque Te ^* . In addition, ^the motor ECU 40 that receives the target rotational speed Nm1 ^* , the torque command Tm1 ^* , and the torque command Tm2 ^* drives the motor MG1 under the torque command Tm1 ^* , and at the same time drives the motor MG2 under the torque command Tm2*. , Switching control of the switching element of 42 .

In step S120, when it is determined that the required power Pe ^* is below the threshold value Pref, it is determined to be the motor operation mode, and the engine 22 is stopped when the engine 22 is running (step S220), and the torque command Tm1 ^* of the motor MG1 is set to a value of 0 ( Step S230), after that, execute the processing of steps S180-S210.

In step S130, when it is determined that the engine 22 is not running, the excess output request flag Fout is set to a value of 1 (step S240), and the torque Tcr for cranking the engine 22 is set as the torque command Tm1 of the motor MG1. ^* (step S250). Then, it is determined whether or not the rotational speed Ne of the engine 22 is greater than a threshold value Nref (step S260). When the rotational speed of the engine 22 is below the threshold value Nref, the processing of steps S180 to S210 is performed, and when the rotational speed Ne of the engine 22 is greater than the threshold value Nref, fuel injection control or ignition control of the engine 22 is started (step S270), and steps S180 to S210 are performed. processing. Here, the threshold Nref is set to the rotational speed of the engine 22 at which fuel injection control or ignition control is started, for example, 800 rpm or 1000 rpm or the like.

The drive control has been described above. As described above, in this driving control, when the accelerator opening degree Acc is larger than the threshold value Aref or when the engine 22 is started, the excess output request flag is set to a value of 1 (steps S150, S240). In addition, in the drive control, when setting the torque command Tm2 ^* of the motor MG2, the output limit Wout of the storage battery 50 is used (step S180). Next, management of the output limit Wout of the battery 50 used for such drive control will be described.

When the management routine illustrated in FIG. 3 is executed, the battery ECU 52 first executes the input of the voltage Vb from the voltage sensor 51a or the current Ib from the current sensor 51b, the battery temperature Tb from the temperature sensor 51, the remaining capacity (SOC), and the excess output requirement. Processing of data necessary for output management of the storage battery 50 such as the flag Fout (step S300). Here, for the remaining capacity (SOC), a value obtained by integrating the current Ib is input through a predetermined address of the unshown RAM of the battery ECU 52, and the excess output request flag Fout is communicated from the electronic control unit 70 for hybrid power. Pass the input.

After such data is input, the output limit Wout of the storage battery 50 is set based on the input battery temperature Tb and remaining capacity (SOC) (step S310). Here, the set output limit Wout is predetermined as the rated output of the battery 50 and can be set according to the temperature characteristics of the battery 50 or the characteristics of the state of charge (SOC). Then, it is checked whether the excess output request flag Fout is set to a value of 1 (step S320). As described above, in the driving control, when the accelerator opening Acc is larger than the threshold value Aref, or when the engine 22 is started, the value 1 is set to the excess output request flag Fout. When the exceeded output request flag Fout is not set to the value 1, the output management routine is terminated. Therefore, the rated output is set as the output limit Wout.

When the excess output request flag Fout is set to a value of 1, it is determined whether the specified time T1 has elapsed from the execution of the previous excess output processing (the processing of steps S350 to S410 until the output limit Wout is set to an output larger than the rated output and released). Step S330). Here, the predetermined time T1 is set as an interval at which the excess output processing is performed, and can be determined by the performance of the storage battery 50 or the magnitude of the allowable excess output. When the predetermined time T1 has not elapsed since the previous execution of the excess output processing, it is determined that the excess output processing should not be executed, and the output management routine is terminated here. At this time, the rated output is also set as the output limit Wout.

When the predetermined time T1 has elapsed since the execution of the previous excess output process, it is determined whether or not the predetermined time T2 has elapsed since the start of the current excess output process (step S340). Here, the predetermined time T2 is set as a time limit within which the excess output process can be continuously performed, and can be determined by the performance of the storage battery 50 or the size of the allowable excess output. When the predetermined time T2 has not passed, the output Wb of the storage battery 50 is calculated by the product of the voltage Vb and the current Ib (step S350), and the deviation from the output limit Wout set as the rated output is calculated as the excess output ΔW (step S360). ). Then, when the calculated excess output ΔW is a positive value (step S370), the value multiplied by the excess output ΔW and the start interval time Δt (8 msec in the embodiment) of the output management routine is accumulated to calculate the output energy Eb (step S380), compare the calculated output energy Eb with the threshold value Eref (step S390). That is, the excess output ΔW exceeding the rated output of the storage battery 50 is time-integrated from the start of the excess output process, and the integrated value is compared with the threshold value Eref as the output energy Eb. Here, the threshold value Eref is a numerical value for judging the end of the output processing beyond the limit, and the output exceeding the rated output of the storage battery 50 is set as the energy within the executable range, which can be determined by the performance of the storage battery 50 . When the output energy Eb is less than the threshold value Eref, it is judged that the output processing can continue to be exceeded, and the output limit Wout of the rated output is set plus the specified excess output Wset as an output part that is allowed to exceed, and it is set as a new output limit Wout( Step S400), end the output management routine. Here, the predetermined excess output Wset sets the upper limit output that can be output from the battery 50 exceeding the rated output, and can be determined by the performance of the battery 50 . After the excess output request flag Fout is set to a value of 1, when the output management routine is executed, the rated output is set as the output limit Wout. The torque command Tm2 ^* of the motor MG2 is set inside, and the output ΔW will not be a positive value if it exceeds. In addition, at this time, the output limit Wout plus the predetermined value exceeding the output Wset is set as the output limit Wout, and when the drive control is executed thereafter, the torque command Tm2 ^* of the motor MG2 can be set by only the predetermined exceeding output Wset. bigger. Thus, only the prescribed exceeding permission of output Wset causes only a delay in the start-up interval time of the output management routine, but since this time is 8 msec in the embodiment, the driver does not feel the time delay.

In addition, when the output energy Eb is above the threshold value Eref, in order to end the excess output management, the output energy Eb is set to a value of 0, and the excess output request flag Fout is set to a value of 0 (step S410), and the output management routine is ended. . In addition, in this embodiment, setting the excess output request flag Fout to a value of 0 is realized by transmitting a control signal from the battery ECU 52 to the output of the hybrid electronic control unit 70 through communication. In addition, even if the output energy Eb has not reached the threshold value Eref, when it is determined in step S330 that the predetermined time T2 has elapsed since the start of the current excess output process, the excess output process is similarly terminated.

7 is an explanatory diagram showing an example of temporal changes in the accelerator pedal opening Acc and the output Wb of the battery 50 when the driver depresses the accelerator pedal 83 a lot at the time of starting. When ^the accelerator pedal 83 is depressed more, the required power Pe ^* is set according to the corresponding accelerator pedal opening degree Acc. , the output limit Wout of the storage battery 50 is a value obtained by adding a predetermined excess output Wset to the rated output. The output Wb of the storage battery 50 rises sharply due to the output of the motor MG2 and the rotation of the crankshaft caused by the motor MG1, and exceeds the rated output. However, since the output limit Wout limits the torque command Tm2 ^* of the motor MG2, it does not exceed the output limit Wout( Rated output + specified excess output Wset). When the engine 22 is started, since the output from the engine 22 is generated by the motor MG1, the output Wb of the battery 50 temporarily decreases, but as the driver continues to depress the accelerator pedal 83 more, the vehicle speed V increases, and the output Wb of the battery 50 becomes Output limit Wout. Meanwhile, the battery ECU 52 repeatedly executes the output management routine of FIG. 3 , and calculates the output energy Eb that is the time integral over the output ΔW. In FIG. 7 , the hatched area of "battery output Wb" corresponds to the output energy Eb. When the output energy Eb reaches the threshold value Eref, the output limit Wout returns to the rated output.

According to the hybrid electric vehicle 20 of the present embodiment described above, until the output energy Eb which exceeds the rated output of the battery 50, which is the time integral of exceeding the output ΔW, reaches the threshold value Eref, the output energy of the battery 50 that exceeds the rated output by only one The output exceeding the output Wset is set as the output limit Wout, and the motor M or the motor MG2 is driven and controlled within the limit range of the output limit Wout, so that the performance of the battery 50 can be further exhibited. As a result, the performance of the vehicle can be improved. Furthermore, when the predetermined time T2 elapses from the execution of such excess output processing, even if the output energy Eb does not reach the threshold value Eref, the excess output processing is terminated, so that the output exceeding the rated output of the battery 50 can be suppressed for a long time.

In the hybrid vehicle 20 of this embodiment, when the predetermined time T2 has elapsed since the start of the over output process, the over output process is terminated even if the output energy Eb does not reach the threshold value Eref, but such a time limit does not matter.

In the hybrid vehicle 20 of this embodiment, when the accelerator opening Acc is larger than the threshold value Aref or when the engine 22 is started, a predetermined excess output Wset as an upper limit output output from the battery 50 that can exceed the rated output is used. A predetermined excess output Wset set according to the accelerator opening degree Acc or the temperature of the battery 50 may also be used. In addition, in the hybrid electric vehicle 20 of the present embodiment, the predetermined time T2 is used as the time limit within which the exceeding output process can be continuously performed, but the predetermined time T2 set according to the accelerator opening degree Acc or the temperature of the battery 50 may also be used. . In such a case, since only exceeding the output and the limit time can be considered, it is needless to say that the calculation of the output energy Eb may not be performed. Such a structure will be described in the second embodiment below.

2. Embodiment 2

The hybrid electric vehicle 20B of the second embodiment is the same as the hybrid electric vehicle 20 of the first embodiment in terms of hardware and processing except that the output management routine executed by the battery ECU 52 is different. Therefore, regarding the hardware configuration of the hybrid vehicle 20B of the second embodiment, the same components as those of the hybrid vehicle 20 of the first embodiment are denoted by the same reference numerals, and therefore detailed description thereof will be omitted. In addition, since the drive control routine executed by the hybrid electronic control unit 70 of the hybrid vehicle 20B of the second embodiment is also the same as the drive control example executed by the hybrid electronic control unit 70 of the hybrid vehicle 20 of the first embodiment The process is the same, and its detailed description is omitted here.

FIG. 8 is a flowchart showing an example of an output management routine executed by battery ECU 52 of hybrid vehicle 20B according to the second embodiment. This routine is repeatedly executed at predetermined time intervals (for example, every 8 msec). When executing the output management routine, the battery ECU 52 first executes the input of the necessary data in the output management of the battery 50 such as the battery temperature Tb or the remaining capacity (SOC), the excess output request flag Fout, and the accelerator pedal opening Acc from the temperature sensor 51c. processing (step S500). Here, for the remaining capacity (SOC), a value obtained by integrating the current Ib is input through a predetermined address of the unshown RAM of the battery ECU52, and for the excess output request flag Fout and the accelerator pedal opening degree Acc, a value for hybrid power is input. The electronic control unit 70 communicates inputs by means of communication.

After the data is input in this way, based on the input battery temperature Tb and remaining capacity (SOC), a predetermined output limit Wout is set as a rated output of the storage battery 50 (step S510). Then, it is checked whether the excess output request flag Fout is set to a value of 1 (step S520). As described above, in the second embodiment, also in the driving control, when the accelerator opening Acc is larger than the threshold value Aref or when the engine 22 is started, the value 1 is set to the excess output request flag Fout. When the exceeded output request flag Fout is not set to the value 1, the output management routine is terminated. Therefore, the rated output is set as the output limit Wout. When the excess output request flag Fout is set to a value of 1, it is determined whether or not a predetermined time T1 has elapsed since the previous execution of the excess output process (step S530). The predetermined time T1 is as described above. When the predetermined time T1 has not elapsed since the previous execution of the excess output processing, it is determined that the excess output processing should not be executed, and the output management routine is terminated here. At this time, the rated output is also set as the output limit Wout.

When the predetermined time T1 has elapsed since the execution of the previous excess output processing, the excess output Wset is set based on the input accelerator pedal opening degree Acc and battery temperature Tb (step S540), and at the same time, the excess output Wset is set based on the same accelerator pedal opening degree Acc and battery temperature Tb. , set the time limit T2 (step S550). The accelerator pedal opening Acc is data reflecting the driver's output request, and the battery temperature Tb is data reflecting the state of the battery 50, so by setting the exceeding output Wset or the limit time T2 according to the accelerator pedal opening Acc and the battery temperature Tb, it is considered that The driver's output request and the state of the battery 50 are shown. In the present embodiment, the excess output Wset is set in a tendency to increase as the accelerator pedal opening degree Acc increases and to decrease as the battery temperature Tb increases. The limit time T2 is set so that it tends to be longer as the accelerator opening degree Acc is larger and to be shorter as the battery temperature Tb is higher. FIG. 9 shows an example of the relationship between the accelerator opening degree Acc, battery temperature Tb, and excess output Wset, and FIG. 10 shows an example of the relationship between the accelerator opening degree Acc, battery temperature Tb, and the limit time T2.

After setting the excess output Wset and the limit time T2 in this way, it is determined whether or not the predetermined time T2 has elapsed since the start of the excess output process this time (step S560). When the predetermined time T2 has not elapsed since the start of the current excess output process, it is judged that the excess output process can be continued, and the output limit Wout set as the rated output is added to the excess output Wset set as the allowable output output, and the result is calculated. As a new output limit Wout setting (step S570), the output management routine ends. Accordingly, the allowable output exceeding the rated output is only the output exceeding the output Wset set based on the accelerator pedal opening degree Acc and the battery temperature Tb. Also, when the predetermined time T2 has elapsed since the start of the current excess output process, the excess output request flag Fout is set to a value of 0 in order to end the excess output process (step S580), and the output management routine is terminated. Thereby, excess output from the storage battery 50 can be suppressed.

According to the hybrid electric vehicle 20B of the second embodiment described above, when the driver depresses the accelerator pedal 83 more or when the engine 22 is started, the excess output Wset set based on the accelerator pedal opening Acc and the battery temperature Tb of the battery 50 is increased. The upper rated output is set as the output limit Wout, and the motor MG1 or the motor MG2 is driven and controlled within the limited range of the output limit Wout, so that the performance of the battery 50 can be further exerted. As a result, the performance of the vehicle can be improved. Furthermore, since the excess output exceeding the rated output is limited until the limit time T2 based on the accelerator pedal opening Acc and the battery temperature Tb, output exceeding the rated output of the battery 50 for a long time can be suppressed.

In the hybrid vehicle 20B of the second embodiment, in the output management routine, the excess output Wset and the limit time T2 are set based on the accelerator pedal opening Acc and the battery temperature Tb of the battery 50, but it can be set based on the accelerator pedal opening degree Acc. Acc and the battery temperature Tb of the storage battery 50 are set to exceed the output Wset. For the limit time T2, a predetermined time can be used. On the contrary, the limit time T2 can be set according to the accelerator pedal opening degree Acc and the battery temperature Tb of the battery 50. For In excess of the output Wset, a predetermined output set in advance may be used.

In the hybrid vehicle 20B of the second embodiment, when the driver depresses the accelerator pedal 83 a lot or when the engine 22 is started, the excess output from the battery 50 exceeding the rated output is allowed in accordance with the accelerator pedal opening degree Acc and the battery output of the battery 50. The temperature Tb is set within the range of the excess output Wset and the limit time T2, but the excess output from the battery 50 exceeding the rated output can also allow the output energy Eb described in the first embodiment up to the threshold value Eref, according to the accelerator pedal. degree Acc and the battery temperature Tb of the storage battery 50 are set within the range exceeding the output Wset and the limit time T2. In this way, excess output exceeding the rated output from the storage battery 50 can be tolerated more suitably.

In the hybrid electric vehicles 20 and 20B of the first embodiment or the second embodiment, the drive control routine is executed by the hybrid electronic control unit 70, and the output management routine is executed by the battery ECU 52, but the output management routine may also be executed by the hybrid vehicle. Power is performed with the electronic control unit 70 .

In the hybrid vehicles 20 and 20B according to the first embodiment or the second embodiment, when the accelerator opening Acc is larger than the threshold value Aref or when the engine 22 is started, the excess output request flag Fout is set to a value of 1 to perform excess output processing. However, the over output processing may be executed only when the accelerator opening Acc is larger than the threshold value Aref, or the over output processing may be executed only when the engine 22 is started. In addition, the excess output process may be executed at times other than when the accelerator opening degree Acc is larger than the threshold value Aref and when the engine 22 is started.

In the hybrid electric vehicles 20 and 20B of the first embodiment or the second embodiment, the reduction gear 35 outputs the power of the motor MG2 to the ring gear shaft 32a after being shifted. As illustrated by 120, the power of the motor MG2 may also be connected to an axle (axle connected to the wheels 64a, 64b in FIG. 11 ) different from the axle connected to the ring gear shaft 32a (the axle connected to the drive wheels 63a, 63b).

In the hybrid electric vehicle 20, 20B of the first embodiment or the second embodiment, the power of the engine 22 is output to the ring gear shaft 32a as a drive shaft connected to the drive wheels 63a, 63b through the power distribution and integration mechanism 30, However, as exemplified in a hybrid vehicle 220 of a modified example in FIG. 12, an inner rotor 232 connected to the crankshaft 26 of the engine 22 and an outer rotor connected to a drive shaft that outputs power to the drive wheels 63a and 63b may be included. 234 , a pair of rotor motors 230 that transmit a part of the power of the engine 22 to the drive shaft and convert the rest of the power into electric power.

In the hybrid electric vehicle 20, 20B of the first embodiment or the second embodiment, and the hybrid electric vehicle 120, 220 of the above-mentioned modified example, the power output from the engine 22 is connected to the axle with the input and output of electric power and power. However, the power output from the engine 22 may not be output to the drive shaft connected to the axle.

In the embodiment, the output management of the storage battery according to the present invention is applied to the output management of the storage battery 50 mounted on the hybrid vehicle 20, 20B, but it is also applicable to vehicles other than the hybrid vehicle 20, 20B, The output management of batteries on mobile bodies such as aircrafts and ships is also applicable to the output management of batteries mounted on devices outside such mobile bodies.

Above, specific embodiments of the present invention have been described using examples, but the present invention is not limited to these examples, and it goes without saying that various forms can be employed without departing from the gist of the present invention.
