Abstract: PROBLEM TO BE SOLVED: To provide a power transmission for vehicles capable of controlling reduction in regenerative efficiency when kinetic energy caused by running of a vehicle is regenerated by a regenerative device. SOLUTION: Power for a source of driving force of a vehicle is transmitted to a transmission, and the transmission comprises a first power transmitting member and a second power transmitting member. Kinetic energy caused by running of the vehicle is transmitted to the source of driving force via the first power transmitting member from the second power transmitting member. Further, the regenerative device regenerating the above kinetic energy is connected with the second power transmitting member in the power transmission for vehicles. When the above kinetic energy is regenerated by the regenerative device, power transmitting efficiency control means (step S1 and step S2) lessening power transmitting efficiency set between the second power transmitting member and the first power transmitting member is provided.

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
