    Abstract: PROBLEM TO BE SOLVED: To restrain shock that is apt to occur when regenerating brake power by a motor is reduced during brake operation in a vehicle having a motor for inputting/outputting power to/from the axle. SOLUTION: When stepping of a brake pedal 85 is continued under accelerator off state in a hybrid automobile 20, a target torque Tr* is set based on a temporary target torque Trtmp which is the sum of a request regenerative braking torque RBT based on a request regenerative braking power RBF* set by a brake ECU 95 and a base torque Tb being outputted to a ring gear shaft 32a when the brake pedal 85 is not stepped under accelerator off state. When a torque outputted at least to the ring gear shaft 32a falls within a predetermined range including a value 0, the target torque Tr* is set to vary gently based on the temporary target torque Trtmp and upper and lower limits Trt=Trt2 (S170-S200).

    Abstract: PROBLEM TO BE SOLVED: To exert creep torque on a vehicle with an instruction to increase or decrease the creep torque and the acceleration of the vehicle taken into account. SOLUTION: When an instruction to increase or decrease a creep torque is given (S150), the following processing is carried out. When the acceleration a of the vehicle exceeds a threshold value A1 (S170), the rate Ck of incorporation of an instructed amount Ks of increase or decrease in creep torque into an amount K of increase or decrease in torque is reduced to a value lower than 100% (S180 to S210) until the acceleration a becomes equal to or lower than a threshold value A2 lower than the threshold value A1 (S230, S240). Using an amount K of increase or decrease in torque set smaller than in cases where the instructed amount Ks of increase or decrease is set without change, a torque command Tm2* as a creep torque command is set (S220, S270). Thus, it is possible to exert a creep torque on the vehicle with the instruction to increase or decrease creep torque and the acceleration of the vehicle taken into account.

    解决方案：当给出增加或减小蠕变扭矩的指令时（S150），进行以下处理。 当车辆的加速度a超过阈值A1（S170）时，将指令量Ks的增加或减小的蠕变转矩的速度Ck降低到低于扭矩的增加或减少量K 100％（S180〜S210），直到加速度a变为低于阈值A1以下的阈值A2（S230，S240）。 使用与不改变指定量Ks增加的情况相比，扭矩设定的增减量K小，设定作为蠕变转矩指令的转矩指令Tm2 *（S220，S270）。 因此，可以通过增加或减少蠕变扭矩和车辆加速度的指令来对车辆施加蠕变扭矩。 版权所有（C）2007，JPO＆INPIT

    Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration of energy efficiency, and to suppress the power of a battery from becoming insufficient in the case of operating an air conditioner by a remote operation before starting this system. SOLUTION: When a switch to be operated by an operator is turned off, or it is detected that the current traveling location is not present in the periphery of a destination based on data from a navigation system, the charging/discharging request power Pb* of a battery is set so that the remaining capacity of a battery can be made close to a predetermined quantity S1 with which energy efficiency and traveling performance are properly balanced (S240), and when the switch is turned on, and it is detected that the current traveling location is present in the periphery of the destination, the charging/discharging request power Pb* is set so that the remaining capacity of the battery can be made close to a predetermined value S2 which is larger than the predetermined quantity S1 (S250) as preparation for sufficiently achieving the supply of a power to be used by an air conditioner by a remote operation before starting this system next, and an engine or a motor is controlled.

    Abstract: PROBLEM TO BE SOLVED: To enhance a deceleration feeling in the case of traveling in an accelerator off. SOLUTION: The vehicle is configured so that a driving shaft is connected to the output shaft of an engine through a planetary gear mechanism, and two motors are connected to the other rotary elements of the planetary gear mechanism. In the case of traveling by turning off an accelerator, a temporary request braking torque Trtump to the driving shaft and a temporary target rotational frequency Netmp of the engine are set based on a shift position SP and a speed V, and correction coefficients α1 and α2 are set based on road surface slope θ and the speed V, and the temporary request braking torque Trtmp and the temporary target rotational frequency Netmp of the engine are multiplied by the set correction coefficients α1 and α2 so that a request braking torque Tr* and a target rotational frequency Ne* of the engine can be set (S110 to S160). Then, the fuel of the engine is cut, and the engine is rotated by the target rotational frequency Ne* and the request braking torque Tr* is output to the driving shaft. Thus, it is possible to make satisfactory a deceleration feeling regardless of the road surface slope θ. COPYRIGHT: (C)2007,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To properly determine the malfunction of the clutch of a transmission.
    SOLUTION: An automobile has a motor and the transmission for transmitting power from a motor to be output to a driving shaft with a change in the connected condition of the clutch. Herein, a rotating speed difference ΔN as an absolute value for a deviation between a rotating speed Nm2 of the motor and (Nr×Gr) that a rotating number Nr of the driving shaft is multiplied by a gear ratio Gr of the transmission is calculated (S110). When the calculated rotating speed difference ΔN is a threshold value Nref2 or more (S130), the rotating speed difference ΔN is integrated to calculate a time integration value In (S140), and when the calculated time integration value In gets to a threshold value Inref or more, the malfunction of the clutch of the transmission is determined (S160, S170). Thus, the malfunction of the clutch of the transmission is determined earlier even when the rotating speed Nm2 of the motor is not so increased.

    Abstract: PROBLEM TO BE SOLVED: To suppress an input of excessive power to a battery. SOLUTION: In an automobile, a drive shaft connected to an engine, a motor MG 1 and a vehicle shaft is connected to a planet gear mechanism, the drive shaft is connected to a motor MG 2 via a transmission, and a battery is prepared to exchange power with the motors MG 1 and MG 2. When upshifting is requested (S120), request power Pe* is corrected in a reducing direction (S130) and the engine and the motors MG 1, MG 2 are controlled by the use of the corrected request power Pe* (S160-S230). Consequently, torque directly transmitted from the engine to the drive shaft is reduced and torque outputted from the motor MG 2 is increased. Thus, the input of the excessive power to the battery is suppressed even if the torque outputted from the motor MG 2 is temporarily reduced in order to cancel inertia torque in upshifting.

    Abstract: PROBLEM TO BE SOLVED: To prevent a vehicle from rapidly decelerating when any abnormality is generated in a motor MG2.
    SOLUTION: When any abnormality may be generated in a motor MG2 since the revolution Nm2 of the motor MG2 is increased due to the abnormality of the clutch of a change gear 60, the connection of a rotary shaft 48 of the motor MG2 to a link gear shaft 32a connected to driving wheels 39a and 39b is released by turning off the clutch of the change gear 60. Thus, it is possible to prevent a vehicle from rapidly decelerating when any abnormality is generated in the motor MG2. Also, it is possible to output a power from an engine 22 to the link gear shaft 32a even when any abnormality is generated in the motor MG2.
