摘要： PROBLEM TO BE SOLVED: To more properly change the change gear stage of a transmission even when the change of the number of revolutions of an engine during shifting transmission is large, and it is impossible to detect the number of revolutions per minute of a driving shaft. SOLUTION: In an automobile where an engine, a first motor and a driving shaft are connected to a planetary gear mechanism, and a second motor is connected via a transmission to the driving shaft, when the number of revolutions of the driving shaft cannot be detected during speed change, and an engine revolution deviation ΔNe is a threshold Nref or more (S120, S140, S240), the rotational frequency Nr* for control is set under the consideration of not only the current number of revolutions Ne and the number of revolutions Nm1 of the first motor but also the previous number of revolutions (previous Ne) of the engine and the number of revolutions (previous Nm1) of the first motor (S250). Then, the number of revolutions Nm2* of the second motor after speed change is set by using the number of revolutions Nr* for control and the change gear stage of the transmission is changed according to the synchronization of the number of revolutions Nm2 of the second motor.

摘要： PROBLEM TO BE SOLVED: To provide a controller for a hybrid vehicle capable of suppressing favorably a speed change shock from being generated from a transmission, in the hybrid vehicle of transmitting motive power of an electric motor to a wheel side output shaft via the transmission. SOLUTION: This hybrid vehicle is provided with a power distribution mechanism 20 for distributing motive power of an internal combustion engine 16 to the wheel side output shaft 6 and the first motor generator 18, and the transmission 14 for transmitting motive power of the second motor generator 12 to the wheel side output shaft 6. An electronic controller 30 conducts deceleration control for increasing a deceleration for the vehicle by supplying electricity to the first motor generator 18 during the stop of an operation for the internal combustion engine 16, and rotation synchronization control for regulating a rotation speed of the second motor generator 12 before a speed change to a rotation speed after the speed change, in the shift of the transmission 14. The execution of the deceleration control is prohibited until finishing the execution of the rotation synchronization control, when the execution of the deceleration control is requested to be executed after the rotation synchronization control is started to be executed.

摘要： PROBLEM TO BE SOLVED: To suppress the drop of torque in switching the shift level of a transmission. SOLUTION: In this vehicle, an engine, a first motor, and a driving shaft are connected to the rotary element of a planetary gear mechanism, and a second motor is connected through a transmission to the driving shaft, and a deviation between the target number of revolutions Ne* of an engine and the current number of revolutions Ne is offset, and the engine and the two motors are controlled so that a request power can be output to the driving shaft. In up-shifting the transmission in such a status that positive torque can be output from the second motor, a torque compensation timing(torque compensation request flag F) is set, based on a rotational deviation between the target number of revolutions Ne* and the number of revolutions Ne, and the target number of revolution Ne* is decreased by every prescribed value in each prescribed time in this timing. Thus, a direct transmission torque to be output from the engine through the first motor to the driving shaft can be appropriately increased regardless of the rotational deviation, and the drop of the torque in switching the shift level can be effectively suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a controller of a vehicle capable of suppressing shock caused when gear shift is performed by a transmission. SOLUTION: This controller of a vehicle comprises a transmission having first to fourth rotating elements, a first drive force power connected to the first rotating element, a rotating device connected to the second rotating element, an output member connected to the third rotating element, and a rotational speed control mechanism adding a force to the fourth rotating element and controlling the rotational speed of the fourth rotating element. The controller can change a gear shift ratio between the first drive force power and the output member and performs a gear shift control to change a force added from the rotational speed control mechanism to the fourth rotating element. The controller also comprises a gear shift control means which when the gear shift control is performed, after the rotational speed of the second rotating element is changed to a rotational speed after the gear shift control is performed, a force added to the fourth rotating element is changed (step S3 to step S13).

摘要： PROBLEM TO BE SOLVED: To suppress shock caused by an increase in direct transmission torque when temporarily correcting reduction in a driving power-related target value so as to moderate a drop of output shaft torque in a torque phase of an automatic transmission in a controller of a hybrid driving device of which the sub-power source is connected to an output shaft via the automatic transmission and which is controlled so as to achieve the driving power-related target value. SOLUTION: When a request output shaft torque T R is temporarily reduction corrected by a request output gradually reducing means 136 prior to the torque phase so as to moderate the drop of the output shaft torque caused in a torque phase in a shift process of a transmission 22, since at least one of an engines 24, a first motor generator MG1 and a second motor generator MG2 is controlled by a direct torque increase suppressing means 144 so as not to increase the direct torque to an output shaft 14, an angle of start of the drop of the output shaft torque is moderated to suppress the drop shock, and the shock caused by an increase in direct torque is also suppressed.

摘要： PROBLEM TO BE SOLVED: To suppress unexpected fluctuation of drive force and suppress overrotation of a motor when shift inhibition is removed. SOLUTION: When a temperature of lubricant oil Toil is lower than a predetermined temperature Tref immediately after a system starts up, a value 1 is set in a shift inhibition flag F. When the temperature of the lubricant oil Toil becomes higher than the predetermined temperature Tref in a state that Lo-Hi shift of a transmission is inhibited (S120), the shift inhibition flag F is reset to a value 0 when a vehicle speed V is lower than a vehicle speed Vhi (S150), and the shift inhibition of the transmission is released. Thereby, inconvenience occurring when the transmission is shifted between Lo-Hi in a state that the vehicle speed V is higher than the vehicle speed Vhi as a vehicle speed for Lo-Hi shift, for example, inconvenience such as generation of a torque shock in accordance with fluctuation of the drive force or overrotation of a motor MG 2 mounted on the transmission can be prevented.
