摘要： PROBLEM TO BE SOLVED: To suppress generation of shocks of chattering or gear rattle sound in a gear mechanism and improve energy efficiency. SOLUTION: In an automobile whose engine and a motor are connected with a driving shaft attached to an axle through a gear mechanism, when the stop of the engine is requested (S120, S210) and request torque Tr* required for the driving shaft is smaller than a threshold value Tref and a vehicle speed V is lower than a threshold value Vref (S220, S230), the engine is idled (S240). Therefore, the generation of the shocks of the chattering or the gear rattle sound in the gear mechanism is suppressed. On the other hand, when the vehicle speed V is the threshold value Vref or higher although the request torque Tr* is smaller than the threshold value Tref (S220, S230), operation of the engine is stopped (S250). Therefore, the energy efficiency is improved. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a ball bearing having small dynamic torque and improved seizure resistance and durability. SOLUTION: The ball bearing comprises a plurality of spherical bodies 1 rollingly laid between a raceway surface 4 on the outer peripheral face side of an inner ring 2 and a raceway surface 6 on the inner peripheral face side of an outer ring 3. Herein, a contact point number changing mechanism 9 is provided for increasing the number of contact points at which one of the spherical bodies 1 has contact with the raceway surfaces 4, 6, during low duty with small load which thrusts the spherical body 1 against the raceway surface 6 on the inner peripheral face side of the outer ring 3, compared with that during high duty with great load. Thus, the number of the contact point is reduced during low duty and so small dynamic torque is generated to improve power transmission efficiency and the number of the contact points is increased during high duty and contact bearing pressure between a rolling element and the raceway surface is reduced to prevent or suppress seizure and durability degradation.

摘要： PROBLEM TO BE SOLVED: To provide a planetary gear mechanism for improving durability.
SOLUTION: This planetary gear mechanism holds a pinion gear 10 by a carrier 3 for intermediating the transmission of torque between a sun gear 2 and a ring gear 1. The planetary gear mechanism has a carrier fixing/releasing mechanism for fixing rotation of the carrier 3 when the transmitted torque is large and allowing the rotation of the carrier when the transmitted torque is small; and allows the rotation of the carrier 3 when input torque to the carrier 3 is small; and fixes the rotation of the carrier 3 when the input torque to the carrier 3 becomes large. Thus, a fixing position of the carrier 3 is not fixed to a specific position. That is, a specific pinion gear 10 is not fixed to a fixed position. Thus, a load is not concentrated on the specific pinion gear 10, and durability of the planetary gear mechanism can be improved.

摘要： PROBLEM TO BE SOLVED: To provide the driver of a hybrid vehicle capable of suppressing generation of abnormal sound incident to generation of impact in a meshing mechanism due to engine torque variation even when motor torque is controlled to substantially zero under predetermined conditions. SOLUTION: When the motor torque of a hybrid vehicle is controlled to substantially zero, a decision is made whether abnormal sound is generating in a meshing mechanism or not based on variation in rotational angle of the motor. If abnormal sound is generating, pressing force is increased at the meshing portion in the meshing mechanism by increasing motor torque thus reducing abnormal sound. When motor torque is increased gradually while looking at abnormal sound extinction judgment results attained by monitoring rotational angle, abnormal sound can be reduced surely depending on difference in engine conditions, variation in components and aging without applying an undue torque.

摘要： PROBLEM TO BE SOLVED: To provide a device for control of a hybrid vehicle with an engine and a motor mounted thereon as drive sources, which prevents reduction in fuel economy and reduces gear noise.SOLUTION: When a vehicle is in a gear-noise region, if the amount of lubricant oil Lsum1 (a value regarding the amount of lubricant oil in a trans-axle) to a gear noise site is equal to or smaller than a determination value Llimit 1, it is determined that the amount of lubricant to the gear noise site is insufficient, and the engine is controlled on the basis of a first operation line (that preferentially reduces gear noise) M1, thereby reducing gear noise. When the amount of the lubricant oil Lsum1 is larger than the determination value Llimit 1 and there is a sufficient amount of lubricant oil to the gear noise site, the engine is controlled on the basis of a second operation line M2 close to an optimum operation line, to thereby improve the fuel economy.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus for detecting abnormal sound of a hybrid vehicle capable of detecting generation of abnormal sound in a meshing mechanism due to engine torque variation even when a motor rotates. SOLUTION: An electronic controller calculates a rotational speed Nm2 of a second motor generator, determines whether a fluctuation width ΔNm2 (difference between the maximum value and the minimum value of the rotational speed Nm2) of the rotational speed Nm2 exceeds a predetermined determination width ΔNth2 when the rotational speed Nm2 repeatedly increases and decreases in a predetermined period of time, and determines that fluctuation at an abnormal sound occurring place is large and abnormal sound occurs in a transaxle when the fluctuation width ΔNm2 exceeds the predetermined determination width ΔNth2. In contrast, when the fluctuation width ΔNm2 does not exceed the predetermined determination width ΔNth2, the electronic controller determines that abnormal sound does not occur in the transaxle.
