    Abstract: 【課題】異常気筒燃料カット運転と全気筒燃料カット運転との間のハンチングを発生し難くする。【解決手段】複数の気筒を有するエンジンを備える車両において、ECUは、エンジン作動要求がある場合で、かつエンジンの複数の気筒の一部に異常気筒が含まれている場合、エンジンの排気を浄化する触媒の温度がしきい値未満であるか否かを判定する。触媒の温度がしきい値以上である場合、ECUは、全気筒の燃料供給を停止する全気筒燃料カット運転を行なう。触媒の温度がしきい値未満である場合、ECUは、異常気筒のみ燃料供給を停止する異常気筒燃料カット運転を行なうとともに、正常気筒の点火遅角量に応じてエンジンの出力(パワーおよび回転速度)を制限する。【選択図】図3

    Abstract: PROBLEM TO BE SOLVED: To provide a drive control unit of a hybrid vehicle capable of improving fuel economy.SOLUTION: After a hysteresis domain having a predetermined hysteresis width is defined between a start line and termination line outside a booming noise generation domain specified in advance as a domain in which booming noise attributable to driving of a motor is generated, if a motor operation point indicated with at least one of a motor torque and the number of motor rotations reaches the start line (Yes at S10), a control drive unit of a hybrid vehicle initiates a booming noise avoidance action (S12). If the motor operation point reaches the termination line (Yes at S20), the drive control unit terminates the booming noise avoidance action (S22). For controlling an engine output so that the engine output becomes equal to a certain target engine output (Yes at S14), compared with a case where the engine output is not controlled to become equal to the certain target engine output, the drive control unit causes the termination line to approach the booming noise generation domain (S16).

    Abstract: PROBLEM TO BE SOLVED: To prevent a catalyst of an exhaust emission control device from being overheated. SOLUTION: When accelerator-on/accelerator-off is frequently repeated, a catalyst overheating counter C is increased or decreased by an addition value reflecting an unburnt gas amount flowing into a purifying device by fuel cut return increase and a subtraction value reflecting an unburnt gas amount a three-way catalyst purifies by air (oxygen) flowing into the purifying device by fuel cut, and thereby, a degree of the unburnt gas amount contributing to temperature rise of the three-way catalyst can be estimated. After the catalyst overheating counter C is equal to or more than a first threshold Cref1 showing the overheating state of the three-way catalyst and until the catalyst overheating counter C is less than a second threshold Cref2, a value 1 is set on a return increase forbidding flag F so as to forbid fuel cut return increase, and fuel cut return increase is prevented, thereby preventing the three-way catalyst of the purifying device from being overheated.

    Abstract: PROBLEM TO BE SOLVED: To surely prevent a valve phase from becoming an improper one when stopping an engine, in a variable valve timing mechanism constituted expanding a changeable quantity of the valve phase by motoring when stopping the engine. SOLUTION: A capacitor state determining part 130 determines whether or not to be an engine motoring possible state in response to a capacitor state when stopping the engine by supply electric power from a capacitor. A phase limiting part 120 sets a target phase CAr so as to limit a phase for preventing the valve phase when stopping the engine from becoming the improper phase largely separated from a stopping time target phase, even if the motoring is not performed when stopping the engine, when determining that the motoring is an unperformable state by the capacitor state determining part 130.

    Abstract: PROBLEM TO BE SOLVED: To sufficiently restrain torque shock in initial explosion when starting an internal combustion engine in the midst of an output from an electric motor to a driving shaft under the condition the internal combustion engine is stopped. SOLUTION: A hybrid ECU transmits a combustion start command to an engine ECU when the engine reaches a combustion start engine speed by cranking. The engine ECU transmits an initial explosion advance notification to the hybrid ECU when reaching thereafter to a position in this side by a crank angle θe, compared with ignition timing of an initial explosion cylinder, and ignites thereafter the initial explosion cylinder in the timing rotated by the angle θe. The hybrid ECU transmits a torque command with a counter torque Tα taken into account, to a motor ECU, at timing where a sum tv of the first time t1 from reception of the initial explosion advance notification up to the ignition timing of the initial explosion cylinder in the engine, and the second time t2 until an influence of the torque by the ignition of the initial explosion cylinder appears in the driving shaft thereafter. The influence of the torque acting on the driving shaft is retrained thereby at satisfactory timing, in the initial explosion of the engine. COPYRIGHT: (C)2007,JPO&INPIT

    Abstract: 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

    Abstract: PROBLEM TO BE SOLVED: To suppress degradation in emission immediately after the starting of an internal combustion engine having a cylinder fuel injection valve. SOLUTION: When an engine is started in a condition that a start water temperature Twst is less than a predetermined temperature Tref, a value with a vehicle demand power P* limited by regarding a power limit Pemax1 as an upper limit is set to an engine demand power Pe* (S140-S170) so that the fuel injection amount of the cylinder fuel injection valve is limited until a piston top surface temperature Test1 becomes a predetermined temperature T1 or more for sufficiently vaporizing and completely burning fuel ejected from the cylinder fuel injection valve toward a piston top surface. A torque command Tm2* is set (S200-S220) to output a required torque Tr* to a driving shaft within a range of battery input/output limit Win, Wout, and an engine and a motor are controlled. Thereby, degradation in emission is suppressed which is caused by incomplete combustion of fuel ejected from the cylinder fuel injection valve while corresponding to the required torque Tr*.
