摘要： PROBLEM TO BE SOLVED: To surely start an internal combustion engine and to suppress resonance generated in the start of the engine. SOLUTION: When a battery temperature Tb does not exceed a threshold value Tb1 or a battery output limit Wout does not exceed a threshold value W1 in the start of the internal combustion engine, that is, when it is possible that motoring of the engine is not normally performed depending on a state of a battery, a fuel injection control is started before an engine speed Ne exceeds a threshold value Nref larger than a resonance speed area (S120 to S140) to start the engine. Therefore, the engine is surely started. On the other hand, when the battery can normally perform the motoring of the engine, the fuel injection control is started after the engine speed Ne exceeds the threshold value Nref larger than the resonance speed area (S120 to S140) to start the engine. Therefore, the resonance generated in the start of the engine is suppressed. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题：确保启动内燃机并抑制发动机起动时产生的共振。解决方案：当电池温度Tb不超过阈值Tb1或电池输出限制Wout不超过内燃机启动时的阈值W1时，也就是说，当可能的情况下，发动机通常根据电池的状态不正常执行，在发动机转速Ne超过大于谐振速度区域的阈值Nref之前开始燃料喷射控制（S120至S140）以启动发动机。因此，发动机确实启动。另一方面，当电池正常地进行发动机的电动运转时，在发动机转速Ne超过大于谐振速度区域的阈值Nref（S120〜S140）之后开始燃料喷射控制，以启动发动机。因此，在发动机起动时产生的共振被抑制。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To enable a stable exhaust purification in the case when fuel is injected after active control of an air/fuel ratio is exercised.
SOLUTION: When conditions for exercising an active control are established, a CPU 52 performs the active control in which a lean air/fuel ratio and rich air/fuel ratio are alternated as a target air/fuel ratio. In this case, every time the output value of a rear exhaust sensor 36 is changed, anomaly of the exhaust sensor 36 is determined on the basis of a prescribed reference time for determination. When the rear exhaust sensor 36 is determined as being normal to finish the active control, the following control is exercised. That is, in the case when the target air/fuel ratio just before the finish is a lean air/fuel ratio, the fuel/injection amount is increasingly corrected, so that the operation is continued for a neutralization control time Tntrl by correcting the target air/fuel ratio after finish of the active control to a rich air/fuel ratio. In the case when the target air/fuel ratio is a rich air/fuel ratio, the fuel injection amount is decreasingly corrected by correcting the target air/fuel ratio after finish of the active control to a lean air/fuel ratio. Thus, the amount of oxygen occlusion in an exhaust purification catalyst 31 is controlled to fall in a predetermined neutral range (range in which the purification function is not lowered).

摘要翻译：要解决的问题：为了在执行空燃比的主动控制之后喷射燃料的情况下能够进行稳定的排气净化。解决方案：当建立用于进行主动控制的条件时，CPU52执行以稀空气/燃料比和浓空气/燃料比交替作为目标空燃比的主动控制。在这种情况下，每当后排气传感器36的输出值变化时，基于规定的判定基准时间来确定排气传感器36的异常。当后排气传感器36被确定为正常以完成主动控制时，执行以下控制。也就是说，在完成前的目标空气/燃料比为稀空气/燃料比的情况下，燃料/喷射量越来越多地被校正，从而通过校正目标来继续中和控制时间Tntrl的操作主动控制完成后的空气/燃料比为丰富的空气/燃料比。在目标空燃比浓空燃比的情况下，通过将主动控制结束后的目标空燃比校正为稀空燃比来减少燃料喷射量的校正。因此，将排气净化催化剂31中的氧吸留量控制在规定的中性范围（净化功能不降低的范围）。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To more appropriately update learned values in an unlearned region and secure good startability of an internal combustion engine.
SOLUTION: Out of the learned values in the unlearned region, learned values in a region in which intake air amount is smaller than that in a learn-completed region and which is not positioned in a lean side are updated after guard processing in a guard range R is performed (S190, S200). Out of the learned values in the unlearned region, learned values in a region in which intake air amount is smaller than that in the learn-completed region and which is positioned in the lean side are updated by using the learned values without performing guard processing in the guard range R (S180, S200).

摘要： PROBLEM TO BE SOLVED: To provide a thermal storage system controlling a pump for thermal storage on the basis of a flow rate in a warm-up stroke of an internal combustion engine.
SOLUTION: This thermal storage system controls the power supply to the pump for thermal storage to adjust a present flow rate to a target flow rate. By controlling the pump for thermal storage on the basis of the flow rate, the stable warm-up stroke can be realized by absorbing the influence due to the individual variation of the pump and a piping system, and the change of properties with time. When the warm-up is completed, a value of electric power in completion is recorded as a present learning value. The present learning value is utilized as the initial applied power in the next warm-up stroke.

摘要： PROBLEM TO BE SOLVED: To provide a heat storage system for dispersing a load on a pump.
SOLUTION: The heat storage system operates a warm-up pump 18 in a warm-up stroke and does not operate it in a heat storage stroke. Alternatively, in the heat storage stroke, a heater pump 15 is operated to accelerate the collection of hot water. The collection of the hot water can also be accelerated by increasing the rotating number of a circulation pump 3. Since a great load is exerted on the warm-up pump 18 during warm-up stroke, the heat storage stroke is executed by another pump, whereby the operating frequency of the warm-up pump 18 is reduced and the life of the warm-up pump 18 is elongated.

摘要： PROBLEM TO BE SOLVED: To solve such a problem that the exhaust heat of an inverter is not collected in a hybrid car. SOLUTION: An ECU for the inverter determines whether the inverter cooling water is collected in a thermal storage tank or not (S10). In a case when the inverter cooling water is collected (Y of S10) in an internal combustion engine stopped state (Y of S12), the ECU for inverter compares a temperature of the engine cooling water with a temperature of the inverter cooling water (S14). The ECU for inverter opens a selector valve (S16), when the temperature of the inverter cooling water is higher (Y of S14). COPYRIGHT: (C)2004,JPO
