    Abstract: PROBLEM TO BE SOLVED: To suppress heat generation of a motor, and to perform control that takes into consideration the drive demands of a driver in a vehicle, having a motor capable of outputting power to the axle. SOLUTION: When a torque which is not smaller than a prescribed value is outputted for a prescribed time from a motor, in a state where the vehicle is in the stopped state, while corresponding torque Tmr based on an accelerator opening Acc is being outputted, reduction rate of torque Rd2, which is set based on the accelerator opening Acc (initial accelerator opening Acci) at stoppage and the corresponding torque Tmr, is used for setting a torque command Tm2* so that torque from a motor MG2 is reduced (steps S370, S380); and when a phase, where the current of the motor is concentrated, is changed over (step S330), rate of increase of torque Ri set, based on the accelerator opening Acc in stoppage, is used for setting the torque command Tm2* so as to increase the torque from the motor MG2 (steps S450, S460).

    Abstract: PROBLEM TO BE SOLVED: To suppress generation of noise due to drag of brakes at starting. SOLUTION: When a start request and a release instruction of brakes are made while controlling to keep a brake pressure even when a driver releases a brake pedal during stopping, a standby time tb has not passed a time tref for sufficiently lowering the brake pressure, an accelerator opening Acc or a gradient θ are respectively lower than predetermined thresholds, and there is no need to promptly output power from a drive shaft (steps S100-S130), torque determined by moderating torque Trtmp based upon a driving request of the driver is set as request torque Tr* (steps S150, S160), and a target rotational frequency Ne* or the like for an engine is set by using the set request torque Tr* (steps S170-S220). By this, power smaller than the driving request by the driver can be outputted to the drive shaft, and generation of the noise due to drag of brakes can be suppressed. COPYRIGHT: (C)2007,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To much more surely protect an accumulating means when outputting a power from an internal combustion engine through a power input/output means to a driving shaft because the output of a power from a motor to the driving shaft is invalid. SOLUTION: When the output of a power from a motor MG2 to a ring gear shaft 32a is invalid, the range of a driving force to be input/output from a motor MG1 is set based on a load factor limit Tm1R determined according to input/output limits Win and Wout of a battery 50 and the maximum rated torque of the motor MG1, and an engine 22 and the motor MG1 are controlled so that only the driving force to be output from the engine 22 can be output through a power distribution and integration mechanism 30 and the motor MG1 to the ring gear shaft 32a within the set range of the driving force. Thus, it is possible to prevent any excessive power from being input/output to the battery 50 by setting the range of the driving force of the motor MG1 for transferring a power with the battery 50 based on the input/output limits Win and Wout and the load factor limit Tm1R.

    Abstract: PROBLEM TO BE SOLVED: To make a drive feeling favorable, and to suppress the charging and discharging of an energy storage device by the excess power of the energy storage device. SOLUTION: A hybrid vehicle is equipped with an engine, a first motor and a driving shaft connected to a carrier, a sun gear and a ring gear of a planetary gear mechanism, and a second motor connected to the driving shaft. When the hybrid vehicle is shifted to a brake range, a lower limit speed Nemin of the engine is set on the basis of a vehicle speed V (S106), a driving point (target rotational speed Ne*) of the engine is set based on a requested torque Tr* corresponding to an accelerator opening Acc and outputs engine demand power Pe* (S108, S110, S126). When the target rotational speed Ne* is less than the lower limit speed Nemin, the engine is driven at the lower limit speed Nemin, and the requested torque Tr* is controlled so as to be outputted to the driving shaft.
