    Abstract: PROBLEM TO BE SOLVED: To improve energy efficiency and to miniaturize a motor. SOLUTION: A power distribution integrated mechanism 30 composed of three planetary gears P1-P3, a clutch C1, and a brake B1 is connected to an engine 22 and a drive shaft 65 which is connected to two motors MG1 and MG2 and drive wheels 69a and 69b. At normal time, the clutch C1 is turned off while the brake B1 is turned on so that the power distribution integrated mechanism 30 functions as four-element type. If the motor MG2 rotates in opposite direction when the power distribution integrated mechanism 30 is functioned as four-element type, the clutch C1 is turned on and the brake B1 is turned off to rotate the motor MG2 in forward direction. So, the drop in energy efficiency which can be caused by rotating the motor MG2 in the opposite direction is suppressed. By allowing functioning as a four-element type at normal time, the motors MG1 and MG2 are miniaturized when compared with a three-element type. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To output sufficient torque at a time of start of rotation of a drive shaft in relation to a power output device outputting power to the drive shaft and an automobile loaded with the same and having wheels mechanically connected to a drive shaft. SOLUTION: A power distribution integration mechanism 30 is composed of two planetary gears P1, P2 and is connected to an engine, two motors MG1, MG2 and a drive shaft 65. And a brake B1 is connected to a rotary shaft having the motor MG2 connected thereto. When large power is requested on a drive shaft 65 rotating at relatively low speed and large braking force is requested on a rotating shaft of the motor MG2, part of the braking force is applied by the brake B1 and rest of braking force is applied by the motor MG2. Consequently, requested braking force can be applied even if large braking force exceeding a rated value of the motor MG2 is requested. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To elongate the life by effectively preventing the temperature rise of a battery, in a controller for a hybrid vehicle. SOLUTION: The controller 10 for a hybrid vehicle, which has an engine 12 and a motor generator (MG)14 as drive sources, is equipped with a temperature detector 26 which detects the temperature of the battery 16 serving as a power source for MG14, and an HV-ECU(hybrid control unit)24 which decides the torque command value of MG14, based on the temporal change of the temperature of the battery 16 detected by the temperature detector 26. HV-ECU24 reduces the output torque of MG14 when the degree of temporal change of the temperature of the battery 16 gets over specified threshold. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To provide a 3-phase inverter module for a reduced wiring resistance and an improved cooling performance of a power semiconductor element. SOLUTION: On a flat element mounting surface of a base plate 3, an AC output bus bar 6 and a power supply bus bar 5 of the 3-phase inverter module are mounted through an insulating sheet 4. An IGBT element 8 of an upper arm side is jointed to the power supply bus bar 5 while an IGBT element 9 of a lower arm side is jointed to the AC output bus bar 6. A tab part 62 of the AC output bus bar 6 is jointed to the upper surface of the IGBT element 8 of the upper arm side, and a ground bus bar 7 is jointed to the upper surface of the IGBT element 9 of the lower arm side. Thus, the IGBT elements 8 and 9 are cooled from both main surfaces through the bus bar. COPYRIGHT: (C)2004,JPO

    Abstract: PROBLEM TO BE SOLVED: To provide a drive control system for improving fuel efficiency by suppressing actuation of the driving source during braking for improving starting response and for preventing reverse running of the vehicle caused by releasing the brake on the upslope with high gradient without deteriorating the effect for improving the fuel efficiency. SOLUTION: The driving sources (engine and motor generator) are stopped (S4) when each judgement of steps (S1) to (S3) is YES. Meanwhile when the brake fluid pressure PB does not reach a high first fluid pressure PB1, the brake pedal is released to turn the brake switch OFF. Then the driving source is restarted (S7). When the brake fluid pressure PB exceeds the first fluid pressure PB1 owing to strong depression of the brake pedal when running on the upslope, the driving source is re-started. The re-starting is performed at the braking force which is larger than that of the case where the brake fluid pressure PB becomes equal to or less than a second fluid pressure PB2 (YES in S6), that is, the brake switch is turned OFF.

    Abstract: PROBLEM TO BE SOLVED: To prevent a hybrid vehicle from slipping down, when the vehicle is started on a slope and improve energy efficiency of the power device of the hybrid vehicle which outputs the power from a motor to a drive shaft via a torque converter. SOLUTION: When an acceleration position AP is off, the value of an engine operation flag FE is 0 and when the absolute value of a vehicle velocity V is lower than a threshold Cr (S100-S106), a brake oil pressure PB is compared with a reference oil pressure Pref, which is set according to a gradient θ of a present position (S108-S114). If the brake oil pressure PB is not lower than the reference oil pressure Pref, it is decided that the vehicle is at halt and will not slip down, owing to the braking force of brakes, and the operation of a motor is stopped (S118). If the brake oil pressure PB is lower than the reference pressure Pref, a target revolution Nm* of the motor is set based on the gradient θ and the brake oil pressure PB (S116), and creep torque is outputted from the motor to a drive shaft via a torque converter.
