Abstract: PROBLEM TO BE SOLVED: To properly prevent air fuel ratio from becoming lean at intermittently starting of an internal combustion engine mounted in a vehicle. SOLUTION: An ECU controls the engine mounted in the vehicle. When the engine is started (YES at S10), the ECU determines whether the engine water temperature THw is in a fuel quantity increase correction area (S20) and determines whether the engine start is intermittent start (S30); when the engine water temperature THw is in the fuel quantity increase correction area (YES at S20) and the engine start is the intermittent start (NO at S30), the ECU determines whether intake temperature THa is higher than a threshold (S40); and when the intake temperature THa is higher than the threshold (YES at S40), the ECU controls an injector which injects fuel to the engine to increase the quantity of the fuel (S50).

Abstract: PROBLEM TO BE SOLVED: To quickly discharge evaporation fuel when a large amount of evaluation fuel is captured by an evaluation fuel capturing means without greatly damaging the fuel consumption of an internal combustion engine. SOLUTION: When the value of a purge priority flag Fp is 1 (when evaporation fuel concentration is high, and a target purge rate is high), driving points on a purge priority operation line are adopted as the target operation points of an engine (S120, S140, S150). Thus, the absolute value of a suction pipe negative pressure is made larger than the case that operation points on a fuel consumption optimal operation line are adopted, so that the flow rate of purge gas to be discharged from a canister to a suction pipe can be increased. Meanwhile, when the value of the purge priority flag Fp is 0 (when evaporation fuel concentration is not within a high concentration region), since the necessity of the quick discharge of the evaporation fuel captured in the canister to the suction pipe is low, the operation points on the fuel consumption optimal operation line are adopted (S120, S130, S150). Thus, it is possible to satisfactorily maintain the fuel consumption of the engine. COPYRIGHT: (C)2010,JPO&INPIT

Abstract translation: 要解决的问题：当通过评估燃料捕获装置捕获大量评估燃料时，快速排出蒸发燃料，而不会大大损害内燃机的燃料消耗。 解决方案：当清除优先级标志Fp为1（蒸发燃料浓度高，目标吹扫率高）时，采用清除优先操作线上的驱动点作为目标操作点 发动机（S120，S140，S150）。 因此，使抽吸管负压的绝对值大于采用燃料消耗最佳操作线上的操作点的情况，使得从罐排出到吸入管的吹扫气体的流量可以是 增加。 同时，当清除优先级标志Fp的值为0（当蒸发燃料浓度不在高浓度区域内时），由于将捕获在罐中的蒸发燃料快速排出到吸入管的必要性低， （S120，S130，S150）采用燃油消耗最优运行线的运行点。 因此，可以令人满意地维持发动机的燃料消耗。 版权所有（C）2010，JPO＆INPIT

Abstract: PROBLEM TO BE SOLVED: To make air/fuel ratio control of an internal combustion engine more appropriate when purge control is performed.
SOLUTION: In performing purge control, an engine ECU 24 of a hybrid vehicle derives a purge air amount ga and a purge fuel amount tau on the basis of intake pipe pressure PM from an intake pipe pressure sensor 112 when the intake pipe pressure sensor 112 is functioning normally, and derives the purge air amount ga and the purge fuel amount tau on the basis of a load factor L derived from an intake air flow G obtained from an air flow meter 108 when the intake pipe pressure sensor 112 is not functioning normally, though the purge air amount ga and the purge fuel amount tau tend to have slightly larger errors than in the case of using the intake pipe pressure PM from the intake pipe pressure sensor 112 functioning normally. Thus, even when the intake pipe pressure sensor 112 is not functioning normally, a deviation of an air/fuel ratio caused by the purge control can be appropriately eliminated.

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 promote consumption of deteriorated fuel in a plug-in hybrid vehicle.SOLUTION: An upper limit value of an electricity storage volume is set for a battery 36 used for supplying first and second motors 16, 18 with power. As the battery electricity storage volume reaches a given lower limit value, the battery is charged by starting an internal combustion engine 14. The battery 36 can be charged from an external connection plug 38 connected to an external power source. As a period since stopping of the internal combustion engine 14 reaches a given period or more, the upper limit value of the battery electricity storage volume is lowered compared to the case of the period being less than the given period. This prevents a full charge when the battery 36 is recharged so that the battery electricity storage volume reaches the lower limit value sooner in the next travel, increasing the chance of operating the internal combustion engine to consume deteriorated fuel sooner.
