Abstract: PROBLEM TO BE SOLVED: To prevent an engine from stalling or rotating reversely. SOLUTION: An ECU executes a program including: a step (S102) of increasing or decreasing the number of rotations of a first MG coupled to a sun gear of a power distribution mechanism in the case of selection of an N range (YES, in S100) and executing synchronous control so as to make the number of rotations of a ring gear NR as the number of target rotations NR(T); a step (S114) of prohibiting the synchronous control if the number of rotations of the engine NE is not larger that a threshold A that is a negative value (YES, in S112) during the stop of the engine coupled to a carrier (YES, in S104); and a step (S134) of prohibiting the synchronous control if the number NE is not larger than a threshold B that is a positive value (YES, in S132) during an autonomous operation of the engine (YES, in S120).

Abstract: PROBLEM TO BE SOLVED: To reduce shock possibly generated when a gear stage is formed.
SOLUTION: An ECU executes a program including a step, when an engine is not in a self-sustaining operation (NO in S100) or when an N range is not selected for a traveling range (NO in S110), of using "A", "B", and "C" for a feedback gain in a feedback control of the number of revolutions NS of a sun gear (the number of revolutions of a first MG) of a power dividing mechanism (S130), and a step, when the engine is in the self-sustaining operation (YES in S100) and the N range is selected for the traveling range (YES in S110), of using "X", "Y", and "Z" for the feedback gain in the feedback control of the number of revolutions NR of a ring gear of the power dividing mechanism (S120).

Abstract: PROBLEM TO BE SOLVED: To output a normally rotating directional driving force to a driving shaft, when the driving shaft is reversely rotated, while suppressing charging of an electric storage device such as a secondary battery with excessive power. SOLUTION: When a ring gear shaft as the driving shaft is reversely rotated due to dragging-down of a vehicle at the time of slope starting, a virtual direct transmitting output power Pegtmp which is needed for an engine to output to the ring gear shaft through a power distribution integrated mechanism is set based on requested torque Tr* and rotating speed Nr of the ring gear shaft without charging a battery chargeable to a rated value with excessive power, and the temporary direct transmitting output power Pegtmp is limited by a charging limit power Plim based on input limit Win of the battery to determine direct transmitting output power Peg (S140-S160). An engine requested power Pe* to be output from the engine is set using this power Peg to control the engine and two motors MG1 and MG2 (S170-S230). COPYRIGHT: (C)2008,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To properly suppress electric discharge due to excessive power of a battery device. SOLUTION: If a slip due to idling of a driving wheel occurs during driving is carried out in a motor driving mode while a traction control (TRC) is turned off, for performing reverse traveling, a motor MG2 is controlled with driving restriction so that only the slip up to a second slip velocity lower than a first slip velocity used in forward traveling is allowed (S120-S150, S190). A slip to a certain extent is allowed by using a velocity, which is sufficiently higher than a predetermined velocity to be determined as a velocity to be suppressed by the traction control (TRC), for the first slip velocity as a target slip velocity Vslip* used for forward traveling and the second slip velocity as the target slip velocity Vslip* for the reverse traveling. In this way, electric discharge due to excessive power of a battery can be suppressed properly. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To suppress electric discharge due to excessive power of an electric storage device during reverse traveling. SOLUTION: When reverse traveling is carried out while setting a shift position in an R-position, if a traction control (TRC) off switch is turned on so that traction control (TRC) by a brake ECU is not carried out (S120), a stopped engine is started (S140) or operation of the engine is continued. In this way, a slip due to idling of a driving wheel occurs during reverse traveling, and the engine is started while discharging of a battery is carried out, so that further discharging of the battery is prevented. Consequently, electric discharge due to excessive power of the battery can be reduced when reverse traveling is carried out. COPYRIGHT: (C)2009,JPO&INPIT
