    Abstract: PROBLEM TO BE SOLVED: To suppress charging/discharging by the excessive power of a battery. SOLUTION: When a shift state or a slip state is set (S130, S140), assumed powers Pm1* and Pm2* to be input/output to motors MG1 and MG2 are subtracted from an input/output power Pbat to be input/output to a battery, and averaging is operated to a calculated power deviation Pbd by using a value T2 which is smaller than a value T1 in a normal time as a time constant Tc of averaging (S260, S170), and input/output allowable restrictions Winf and Woutf are set based on input/output restrictions Win and Wout of the battery (S180). Thus, it is possible to suppress charging/discharging by the excessive power of the battery since input/output allowable restrictions Winf and Woutf can be quickly changed in comparison with a normal time.

    Abstract: PROBLEM TO BE SOLVED: To temporarily lower the drive force to be output and thereafter, when it is raised, to output the drive force closer to the drive force which should be output. SOLUTION: Until predetermined time elapses after slip occurs by idling of a driving wheel, upper limit rotation speed is set by using a rate value Nert2 smaller than a rate value Nert1 at normal time (S210), and engine target rotation speed Ne* is set by using upper limit rotation speed Nemax (S240-S260) and also the engine target rotation speed Ne* is set using the upper limit rotation speed Nemax (S240-S260), and torque instruction Tm1*, Tm2* of motors MG1 and MG2 are set so that the engine is operated by the target rotation speed Ne* and the required torque T* for execution is output to the driving shaft in the range of I/O limitation Win and Wout of a battery (S270-S320). Thereby sharp increase of rotation speed of the engine is suppressed and the torque closer to the required torque T* for execution can be output to the driving shaft. COPYRIGHT: (C)2009,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To suppress occurrence of charging and discharging in a capacitor device such as rechargeable battery by unexpected excessive power, when a driving wheel is locked. SOLUTION: When locking of a driving wheel is determined, torque restriction Tm1min and Tm1max are set (S150, S180) by using rotation speed Nm2* for control obtained by performing prediction processing to rotation speed Nm2 of a motor MG2 as a rotation speed of the motor MG2. While setting up a torque instruction Tm1* of the motor MG1 by restricting a temporary torque Tm1tmp so that the engine may be rotated by an objective rotation speed Ne* by these torque restrictions Tm1min and Tm1max, the engine and motors MG1 and MG2 are controlled by setting a torque instruction Tm2* of the motor MG 2 using rotation speed Nm2* for control within the limits of I/O restriction Win and Wout of the battery (S190-S210).

    Abstract: PROBLEM TO BE SOLVED: To reduce shock generated when shifting a transmission for speed-changing motive power from an electric motor to be transmitted to an output side. SOLUTION: The speed change is carried out in accompaniment to two phases of a torque phase and an inertia phase, when the transmission for transmitting the motive power of the motor MG2 to front wheels is up-shifted, correction torque Tchg is set as torque for accelerating a vehicle in the torque phase, based on brake pressure Pb2 of a brake B2 (S340, S350), and the correction torque Tchg is set as torque for decelerating the vehicle in the inertia phase, by multiplying an inertia moment I of a rotary system including a rotor of the motor MG2 with a change (rotation speed variation) ΔN in a rotation speed Nm2 of the motor MG2 (S380- S400). The set correction torque Tchg is output from a motor MG3 to output the motive force to rear wheels, thereby reducing the torque shock generated when changing the speed. COPYRIGHT: (C)2007,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To more surely achieve backward traveling when a shift position is changed from a drive position to a reverse position during the down-shift of a transmission in a vehicle traveling by using a power for forward traveling from an engine and a power to be output from a motor through a transmission. SOLUTION: When the shift position is changed to the reverse position during downshift (S170, S180), an engine is independently operated until the downshift is completed, and a motor is controlled by a torque command Tm2* based on a request torque Tr* (S190, S240). Thus, when the shift position has been changed to the reverse position during the downshift, the torque for forward traveling to be output from an engine to an axle can be suppressed from being larger than a torque for backward traveling to be output from the motor through the transmission to the axle, and that the backward traveling can be much more accurately achieved.

    Abstract: PROBLEM TO BE SOLVED: To suppress input of power to a capacitor device exceeding the input limit when starting an internal combustion engine while a hybrid vehicle is moving by motor. SOLUTION: Intermittent driving forbidden vehicle speed Vref which forbids intermittent driving of an engine 22 is established based on an input limit Win of a battery 50 (S110). If a vehicle speed V is under the intermittent driving forbidden vehicle speed Vref, the engine 22 and motors MG1 and MG2 are controlled so that a requested torque Tr* can be obtained involving the intermittent driving of the engine 22 according to a predetermined start condition (S140) and a stop condition (S150). Meanwhile, if the vehicle speed V is over the intermittent driving forbidden vehicle speed Vref, the engine 22 and motors MG1 and MG2 are controlled regardless the above start conditions and the stop condition so that the requested torque Tr* can be obtained involving continuation of driving of the engine 22 during the driving of the engine 22, and involving cranking of the engine 22 by the motors MG1 and MG2 during stop of the engine 22.

    Abstract: PROBLEM TO BE SOLVED: To perform gear shift of a transmission in a range of input/output limit of a storage device such as a secondary battery, and to prevent occurrence of gear shift shock during gear shift. SOLUTION: When Lo-Hi gear shift of the transmission for shifting the output from a motor and outputting it to a driving shaft is predicted, a required charge/discharge electric power P2 is calculated by adding, to an input limit Win of the battery, a required electric power P1 during gear shift where electric power for charging and discharging the battery is changed in response to the gear shift (S150). When a charge/discharge request electric power Pb* of the battery is less than the required charge/discharge electric power P2, the charge/discharge request electric power Pb* is reset by adding the differential adjusted electric power Pch to the charge/discharge request electric power Pb*, and engine request power Pe* or the like is reset and controlled using the reset charge/discharge request electric power Pb* (S200-S260). Thus, it is prevented from being less than the input limit Win of the battery during the Lo-Hi gear shift. COPYRIGHT: (C)2007,JPO&INPIT
