Abstract: PROBLEM TO BE SOLVED: To suppress a rise in temperature of a motor connected to a drive axle through a transmission.
SOLUTION: When motor temperature Tm is equal to or larger than a threshold T1 or when inverter temperature Tinv is equal to or larger than a threshold T2, a value 1 is set to a motor state judgment flag F, and a Lo-Hi shift line of a transmission is set to a high-vehicle-speed side to make an up-shift speed change difficult (S340, S350); and a motor is driven within a high-load range of low number of revolutions and high torque while a current transmission step (n) of a transmission is in a Hi gear state, and when the motor state judgment flag F indicates the value 1, a down-shift speed change is forcibly made irrelevantly to a Hi-Lo shift line (S400 to S420). Consequently, the motor can be driven in a region of high number of revolutions and low torque, so that a rise in temperature of the motor can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To properly perform the continuous operation of an internal combustion engine when an intermittent operation is inhibited. SOLUTION: When the intermittent operation of an engine 22 is inhibited, and a speed from a speed sensor 88 is within a high vehicle speed region, a motoring mode is executed to operate the motoring of the engine 22 by a motor MG1 by cutting the fuel of the engine 22, and to output a torque matched with a request torque to a ring gear shaft 32a as a drive axle, and when the speed is within a low vehicle speed region, an independent operation mode is executed to operate the independent operation of the engine 22 by stopping the motor MG1, and to output a torque matched with the request torque to a ring gear shaft 32a. Thus, it is possible to improve energy efficiency by executing the motoring mode which is more efficient than the independent operation mode, and to prevent inconvenience due to the execution of the motoring mode in the low vehicle speed region, for example, the continuous discharging of a battery 50.

Abstract: PROBLEM TO BE SOLVED: To suppress feeling of incompatibility to be given to an operator when changing the shift level of a transmission 60 in an automobile 20 where an engine 22 and a motor MG1 and a drive shaft 32a are connected to planet gear mechanism 30, and a motor MG2 is connected through the transmission 60 to the drive shaft 32a. SOLUTION: When the torque command of a motor MG2 is near a value 0, and the shift request of the transmission 60 is not made, an engine 22 is controlled by using rotational frequency which is larger than the target rotational frequency of the engine 22 as practical rotational frequency, and when the torque command of the motor MG2 is near the value 0, and the shift request of the transmission 60 is made, the shift level is changed in such a status that the engine 22 is controlled by using the target rotational frequency of the engine 22 as the practical rotational frequency. Thus, it is possible to suppress any feeling of incompatibility from being given to an operator due to the unexpected change of the rotational frequency of the engine 22 when the shift level of the transmission 60 is changed.

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.
