摘要： PROBLEM TO BE SOLVED: To promote warming and temperature reduction in power transmission and promote warming of an engine, in a vehicle power transmission which is equipped with an electric-type differential section. SOLUTION: The warming and the temperature reduction in the power transmission or the warming of the engine 8 can be promoted, since the way to use multiple electric paths is changed, based on a temperature state of the power transmission 10 or a temperature state of the engine 8. For example, when the warming of the power transmission 10 is necessary, the manner in which to use the electrical path can be changed so as to increase the electrical path amount in the electrical path whose relation with temperature change in the power transmission 10 is strong, so that the warming can be promoted, for the loss incurred in the electrical path. Similarly, for example, when the warming of the engine 8 is necessary, the manner of using the electrical path can be changed so as to reduce the transmission efficiency of the power transmission 10, so that the engine 8 can be warmed, without increasing output torque, if the transmission efficiency is reduced by the amount of increase in the engine output.

摘要： PROBLEM TO BE SOLVED: To provide a device for controlling a vehicle automatic transmission having a motor, which suppresses a shift shock when a constraint is imposed on the control of shift transient characteristics by the motor. SOLUTION: When shift transient characteristics are controlled by motors M(M1, M2), concretely, when simultaneous opposite shift is performed, the workload of a motor M in the control of the shift transient characteristics is decreased according as the rotational speed of the motor M corresponding to a vehicle speed V is low. That is, a shift point control means 84 shifts the shift point of a transmission 30 to a low vehicle speed side according as the constraint on the control of the shift transient characteristics by the motor M is large, so that it is possible to reduce the workload of the motor M by shifting the shift point to the low vehicle speed side, and to reduce influence of the constraint on the shift transient characteristics. As a result, by shifting the shift point to the low vehicle speed side, proper shift shock reduction effects are obtained according to the degree of the constraint. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To improve fuel economy at a high vehicle speed in a driving device having an electric differential transmission and a continuously variable transmission which are connected to an engine, by setting an integrated change-gear ratio according to a change-gear ratio between the two transmissions. SOLUTION: In the vehicular driving device, the electric differential part 20 as a former-stage transmission is provided with a first switching clutch C1 and a second switching clutch C2 for changing a connection-relation with the continuously variable transmission 30 of a latter stage, and is switched to a first differential state wherein a change-gear ratio is large and a second differential state wherein a change-gear ratio is small by switching engagement of the first switching clutch C1 and engagement of the second switching clutch C2 to each other.

The increase of slip amount of the variable transmission part is thereby avoided, so that the deterioration of the durability is prevented. COPYRIGHT: (C)2010,JPO&INPIT
