    Abstract: PROBLEM TO BE SOLVED: To control the number of revolutions of an input shaft of a transmission more appropriately during gear shifting, thereby preventing a power storage device such as a secondary battery from being charged or discharged with excessive electric power. SOLUTION: During gear shifting, the rate of change ΔNm2 (t) in the number of revolutions of a motor at every time (t) from the start to the end of the gear change is calculated on the basis of the number of revolutions of the motor Mn2 inputted by communication, the number of revolutions of a drive shaft Nd, the gear ratios Gpre, Gaft of a transmission before and after the gear change, and hydraulic control for the gear change (S110). Using the rate of change ΔNm2 (t) corresponding to the elapsed time (t) from the start of the gear change, an expected number of revolutions of the motor Nm2est is set as the number of revolutions of the motor MG2 during control (S140). Using the expected number of revolutions of the motor Nm2est, an engine and the motors MG1, MG2 are controlled (S150-S250). In this way, it is possible to keep the battery from being charged or discharged with unexpected excessive power due to computation delay or communication delay when the transmission changes gears.

    Abstract: PROBLEM TO BE SOLVED: To precisely predict the number of revolution of a rotary motor by solving the problem that there is such a case that the actual number of revolutions is largely different from the number of revolutions detected by a sensor or the like in the case of the up-shift of a transmission mechanism when executing the shift of a continuously variable transmission so that the number of revolutions of an engine can be continuously changed before and after the shift of the transmission mechanism in a driving device for a vehicle. SOLUTION: An HV_ECU executes a program including: a step (S100) for detecting the number of revolutions of a first MG based on a signal transmitted from an MG_ECU; a step (S110) for detecting the number of revolutions of a second MG based on a signal transmitted from the MG_ECU; a step (S120) for detecting the target value of the number of revolutions of an engine based on a signal transmitted from an engine ECU; and a step (S130) for predicting the number of revolutions of the first MG by subtracting the product of 1/ρ and the differentiated value of the number of revolutions of the second MG from a value calculated by adding the product of (1+ρ)/ρ and the differentiated value of the target value of the number of revolutions of the engine to the detected number of revolutions of the first MG.

    Abstract: PROBLEM TO BE SOLVED: To provide a controller for a vehicle capable of enhancing controllability for driving force, in the vehicle including a plurality of power sources for driving a plurality of wheels. SOLUTION: A distribution ratio determining part 95 determines a distribution ratio of a request torque F, based on a static load distribution ratio, when a sign of the request torque F is negative. The distribution ratio determining part 95 determines the distribution ratio of the request torque F, based on a dynamic load distribution ratio, when the sign of the request torque F is positive. The distribution ratio determining part 95 determines the distribution ratio, using the static charge distribution ratio and the dynamic load distribution ratio, when the sign of the request torque F is varied. The driving force is thereby prevented from being varied discontinuously in the front and rear wheels of the vehicle, even when the sign of the request torque F varies. COPYRIGHT: (C)2007,JPO&INPIT
