    摘要: PROBLEM TO BE SOLVED: To quickly decrease a diesel particulate filter (DPF) temperature when the temperature of the DPF becomes excessive during the regeneration of the DPF in a hybrid vehicle equipped with an engine and a motor. SOLUTION: When it is decided that the temperature of a DPF becomes excessive, and a battery charging quantity SOC is a high level, the output of a motor is increased, and an engine is made to drag at a predetermined revolution speed or more by the motor (M=3). When the SOC is a low level, the air-fuel ratio of an engine is made rich, and the output of the engine is increased so that it may escape from a low load region, and the motor is driven by an excessive output so that power generation can be performed (M=2).

    摘要: PROBLEM TO BE SOLVED: To provide a controller of a hybrid electric car for satisfactorily reproducing a particulate filter, and for preventing the deterioration of a battery. SOLUTION: Driving force of an engine 2 and driving force of a motor 6 can be transmitted to driving wheels 16 of a vehicle respectively, and when the driving force of the engine 2 is transmitted to the driving wheels 16, and request torque calculated according to the operating state of the vehicle is equal to or less than allowable torque, the engine 2 is controlled to output the request torque alone, and when the request torque is larger than the allowable torque, the engine 2 is controlled to output the allowable torque, and the motor 6 is controlled to output the shortage of the allowable torque for the request torque. Thus, it is possible to more increase the allowable torque in a low revolution region, and to more decrease the allowable torque in a high revolution region when a filter 44 is reproduced in comparison with the case that the filter 44 is not reproduced.

    摘要: 既に挿入されているセンタリング補助部を引き抜くことができる開口部を電動機ハウジングに設けることは既知の方法である。 電動機ハウジングのこの種の開口部は、より構造的に複雑になり、実質的に、電動機ハウジングのコストが付加される。 センタリング補助手段の導入及び引き抜きは、電動機の製造コストが同じく付加される追加の組立ステップである。 本発明の方法によれば、センタリング要素(11)は、ステータハウジング(4)内に一体化され、またロータ(5)をステータ(4)にセンタリングするように位置決めして固定することを可能にする。 前記センタリング要素(11)は、電動機が取付けられると、電動機内に、すなわちステータハウジング(4)内に留まる。 本発明の方法は、ロータとステータとを備える電動機を取付けるために特に適切である。

    摘要: PROBLEM TO BE SOLVED: To bring a clutch surely into an off-state when started by two axle drive, and to lock-release the clutch without driving a motor uselessly. SOLUTION: The clutch 60 is interposed between the motor 51 and wheels 56, an engagement piece 9 in an engagement space between rotary members 4 and 1 at a motor side and a wheel side, and a holder restriction mechanism 21 for switching a holder for holding the engagement piece 9 from a restricted state to a released state or vice versa, is brought into the restricted state to allow rotation transmissions along both normal and reverse directions, and brought into the released state to allow rotation between the both rotary members 4 and 1. A rotation direction estimating means 63 is provided to estimate the drive rotation direction of the motor 51 immediately before a motor stop or a vehicle stop when a vehicle is stopped, the motor 51 is rotation-driven at torque smaller than that capable of driving the wheels 56 reverse-directionally with respect to the motor driving direction estimated by the rotation direction estimating means 63, when driving only another driving system from the stop condition of the vehicle to be started by the two axle drive, and the holder restriction mechanism 21 is thereafter brought into a holder released state.

    摘要: PROBLEM TO BE SOLVED: To smoothly change opening/closing timing of a valve after starting an internal combustion engine. SOLUTION: When a start request for an engine is made, if an oil temperature Toil is not high in S140, a power output device sets a spark start number of rotations Nstart of the engine to a first number of rotations N1 in S150. If the oil temperature Toil is high, since the viscosity of operation oil is low and the oil pressure is slow in increasing, the device sets the number Nstart of the engine to a second number of rotations N2 larger the first number of rotations N1 in S160. By setting torque commands Tm1* and Tm2* using the number Nstart set in such a manner to transmit them to motors MG1, MG2 and by motoring the engine, the device surely unlocks a lock pin of a variable valve timing mechanism from a locking hole even when the oil temperature Toil is high. Therefore, the device can smoothly change the valve timing of an air intake valve after starting the engine. COPYRIGHT: (C)2007,JPO&INPIT

    摘要: PROBLEM TO BE SOLVED: To provide a motor controller which causes no rating over in a step-up/down converter. SOLUTION: This motor controller includes a generator motor MG1 connected to an engine, and a driving motor MG2 connected to a drive shaft of a vehicle. A motor controller 109 controls an inverter 202 so as to convert a first torque command into DC power corresponding to a first target torque command while the first target torque command is changed, and controls an inverter 203 so that the torque corresponding to a second target torque command may be generated with the driving motor MG2 while the second torque command is changed. The step-up/down converter 201 steps up the DC power from a battery 110 and supplies it to the inverter 203, and steps down at least a part of the DC power converted at the inverter 202 and recovers it to the battery 110. The motor controller 109 determines a change rate of the first torque command and the second torque command corresponding to an input/output responding performance of the step-up/down converter 201.
