Abstract: PROBLEM TO BE SOLVED: To reduce unnecessary energy consumption and to prevent abrupt start of a vehicle in a brake hold control releasing time in the vehicle wherein brake hold control is released based on the degree of an acceleration demand by a driver. SOLUTION: An ECU carries out a program including steps S102, S112, S114, and S200. In the step S102, a control accelerator opening used for output control of driving force as the control degree of the acceleration demand by the driver is set to 0 when it is under the brake hold control (S100: YES). In the step S112, if an actual accelerator opening as the actual degree of the acceleration demand by the driver is higher than a predetermined opening A (0) (S106: YES), it is determined that the acceleration demand is given by the driver. In the step S114, a brake hold control releasing instruction is outputted. In the step S200, the control accelerator opening is gradually converged to the actual accelerator opening.

Abstract: PROBLEM TO BE SOLVED: To suppress wasteful energy consumption resulting from a change in an operation point of an internal combustion for changing a range when changing a settable range of a requested drive force required for travelling can be set. SOLUTION: In a state in which a DSS request is made from a driver in an accelerator-off state, a hybrid automobile 20 sets a requested torque Tr* required for travelling within a power range in which at least a lower limit of power is set so small as equivalent to a fourth stage (SP4) rather than a normal power range in which the DSS request is not made and a D position is selected as a shift position SP (S230), and sets a target rotating speed Ne* as a target operation point of an engine 22 by using a restriction similar to that in a normal time (S160). Thereby, the automobile 20 may suppress the wasteful energy consumption resulting from the change in the operation point of the engine 22 while increasing a braking force to be secured in a constant-speed travel control and in a following travel control.

Abstract: PROBLEM TO BE SOLVED: To suppress unexpected torque shock which might occur at shift operation. SOLUTION: When shift operation is performed while braking force is still working on a drive shaft at OFF of an accelerator, a conversion factor k is set based on the deviation ΔNm1 between the number of revolutions Nm1 of a motor MG1 and the last value Nm1 (S112), and direct transmission torque Ter is computed by the use of the set conversion factor k (S114), and the torque command Tm2* for the drive motor is set by the use of this direct transmission torque Ter so as to control it (S116 and S118). Hereby, even if the user changes the revolutions of an engine by shift operation, the car can output the torque based on requested torque Tr* to a drive shaft, whereby it can suppress unexpected torque from being outputted to the drive shaft.

Abstract: PROBLEM TO BE SOLVED: To provide a power output device which smoothly performs gear change of a transmission. SOLUTION: In a car in which an engine, a motor MG1 and a drive shaft are connected to a planet gear mechanism and which is equipped with a motor MG2 connected to the drive shaft via a transmission and a battery which performs exchange of electric power between motors MG1 and MG2, when switching of a status of a transmission from Hi gear to Lo gear is requested, and if a value of a torque instruction Tm2* of the motor MG2 is zero or less(S130, S150), a driving point of the engine is changed to a high torque high rotation side (S160-S190) so that the electric power set up based on the load limitation of the battery as the electric power which is insufficient to perform gear change smoothly may be supplied by the motor MG1. Thereby, electric power required for gear change can be supplied and gear change can be performed smoothly, since generated power by the motor MG1 also becomes large based on dynamic relationship of each rotation element of the planet gear mechanism.

Abstract: PROBLEM TO BE SOLVED: To secure power needed for a change in a gear ratio of a transmission so as to execute a gear ratio change properly. SOLUTION: A gear ratio is changed using a low vehicle speed side speed change line map. The speed change line map is so set that, when a shift lever 81 is operated into a B range, a motor MG1 drives an engine 22 to be adjusted at a higher revolution as a vehicle speed increases, and that the gear ratio of the transmission 60 is changed (down shift) on a vehicle speed side lower than another side on which the gear ratio is changed when the shift lever 81 is operated into another range (D range or the like). As a result, when the gear ratio of the transmission 60 is changed while operating the proper engine braking corresponding to a vehicle speed upon operating the lever 81 into the B range, the consumption power of the motor MG1 resulting from its driving can be reduced, and the same of a motor MG2 needed for the gear ratio change can also be reduced. Hence the power of the motor MG2 that is needed for changing the gear ratio of the transmission 60 is secured, thus the gear ratio change can be executed more properly. COPYRIGHT: (C)2006,JPO&NCIPI

解决方案：使用低车速侧速变化线图改变齿轮比。 变速线图如此设定，当变速杆81动作为B档时，马达MG1随着车速的增加而驱动发动机22进行更高的转速的调整，并且变速器的变速比 在变速杆81操作到另一范围（D档等）时，在变速比变化的另一侧的车速侧下降60（60度）变化（下降）。 结果，当在将杆81操作到B档时，当对应于车辆速度的适当的发动机制动进行变速时变速器60的齿轮比改变，可以减少由其驱动而产生的电动机MG1的消耗功率， 并且也可以减少齿轮比变化所需的马达MG2的相同。 因此，确保了改变变速器60的变速比所需的电动机MG2的动力，因此可以更适当地执行变速比变化。 版权所有（C）2006，JPO＆NCIPI

Abstract: PROBLEM TO BE SOLVED: To prevent an excessive driving force from acting on a drive shaft due to the inertia of a motor while suppressing a decrease in torque to the drive shaft caused when a speed change gear which gears the driving force from the motor and outputs it to the drive shaft is switched to a Hi gear from a Lo gear.
SOLUTION: When the speed change gear is switched to the Hi gear from the Lo gear, a torque command Tm2* is set so as to control the motor so that power outputted from the motor is kept constant, and when the output torque Tmr to the drive shaft exceeds torque Tset outputted to the drive shaft, adjusting the torque ΔTm2 corresponding to an exceeding portion is calculated, the torque command Tm2* of which the torque is reduced by the adjustment torque ΔTm2 is set to control the motor by which the decrease of torque to the drive shaft caused when a speed is changed is suppressed by making use of the inertia of the motor, and the excessive torque upon the drive shaft is prevented from acting by the inertia. As a result, the sense of the incongruity of a driver at changing speed is prevented.
