Abstract: PROBLEM TO BE SOLVED: To compatibly establish prevention of deterioration of an exhaust emission control catalyst and improvement of fuel consumption rate by engine stop.
SOLUTION: When engine target torque is zero torque and a fuel cut condition is satisfied but an engine idles without executing fuel cut since catalyst temperature is in a catalyst deteriorating temperature zone, it is determined whether an engine stop condition is established or not (S300). When the condition is established, it is determined whether load on the exhaust emission control catalyst is heavy or not (S320). If the load is heavy, idling operation is executed (S310). Consequently, relatively low temperature exhaust gas at a time of idling operation forcedly cools the exhaust emission control catalyst, the exhaust emission control catalyst is not kept under a high temperature condition. If the load is not heavy in S320, the engine is stopped (S330). Since air is not circulated in the exhaust emission control catalyst 61, the exhaust emission control catalyst 61 is not exposed to lean atmosphere even if temperature thereof gets high and deterioration thereof is suppressed.

解决方案：当催化剂温度处于催化剂劣化温度区域时，当发动机目标转矩为零转矩和燃料切断条件但发动机空转而不执行燃料切断时，确定是否建立发动机停止条件 （S300）。 当条件成立时，确定废气排放控制催化剂上的负荷是否重（S320）。 如果负载较重，则执行空转操作（S310）。 因此，空转时的相对低温废气强制地冷却废气排放控制催化剂，废气排放控制催化剂不保持在高温条件下。 如果S320中的负载不重，则停止发动机（S330）。 由于空气不在废气排放控制催化剂61中循环，所以即使废气排放控制催化剂61的温度变高并且其劣化被抑制，排气排放控制催化剂61也不暴露于贫气。 版权所有（C）2006，JPO＆NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide an engine electronic device for stably cleaning exhaust gas in restarting an engine after the engine is stopped in the middle of execution of an active control, and to provide a vehicle mounting the engine electronic device thereon. SOLUTION: When an active control routine is interrupted in stop of an engine before the restart of the engine (Yes in S206, S208, S210), OSC of an exhaust catalyst is compared with a predetermined neutral range in the interruption of the active control (S216), and an injection amount TAU in restart is determined based on the comparison result to perform a fuel injection control (S216 to S226). Since the OSC occluded by the exhaust catalyst is easily influenced by a condition in the interruption of the active control compared with influence of air flowing in the exhaust catalyst in the engine stop, the OSC occluded in the exhaust catalyst can be regarded as the OSC in the interruption of the active control with very few problems in accuracy.

解决方案：在发动机重新启动之前中断发动机的主动控制程序时（S206，S208，S210中为“是”），将排气催化剂的OSC与预定中断范围进行比较 基于进行燃料喷射控制的比较结果来决定主动控制（S216）和再起动时的喷射量TAU（S216〜S226）。 由于与发动机停止时的排气催化剂中的空气流动的影响相比，由排气催化剂吸留的OSC容易受到主动控制中断的条件的影响，因此封闭在排气催化剂中的OSC可以被认为是OSC 主动控制的中断精度很少的问题。 版权所有（C）2005，JPO＆NCIPI

Abstract: PROBLEM TO BE SOLVED: To improve fuel economy of a hybrid automobile and to stabilize fuel economy. SOLUTION: This hybrid automobile travels by transmitting power form an engine and power from a motor MG2 to a driving shaft and is capable of storing power generated with a part of the power from the engine by the motor MG1 into a battery. Required power Pr* of a driving shaft is set based on an accelerator opening and battery charging power Pbi is set based on SOC. The sum of both of the power Pr* and the power Pbi is made as engine target power Pe* (S100 to S108). When the engine target power Pe* is less than a prescribed lower limit valve Plow, the engine target power Pe* is changed to the lower limit value Plow and the battery charging power Pbi is also changed according to the change (S112), to operate the engine and the motors MG1 and MG2. Since the lower limit value Plow is set so that efficiency for an output of the engine may be optimum efficiency, the engine can be prevented from being operated in a low output region having bad efficiency.

Abstract: PROBLEM TO BE SOLVED: To reasonably and suitably preheat an engine and its related parts. SOLUTION: A hybrid ECU determines that a driver has an intention of starting traveling when a starter switch is changed over from the off-state to the on-state (S110), the temperature of each item (cooling water in the engine, injector and lubricating oil) is input (S120), the necessity of preheat is determined depending on whether or not each item reaches a suitable temperature range (S130), when preheat is necessary, an engine start permitting flag is set to "0" to inhibit starting of the engine (S140), and subsequently, an instruction for preheating of the item required to be preheated is given to the engine ECU (S150) to end the program. On the other hand S130, when all items reach suitable temperature range, preheating is determined to be unnecessary, and the engine starting permitting flag F is set to "1" to permit starting of the engine (S160) to end the program.

Abstract: PROBLEM TO BE SOLVED: To surely start an engine when the engine is cranked by a motor according to the discharge of a battery. SOLUTION: The lower the temperature T of cooling medium for cooling the engine in the condition of the engine and the lower the remaining capacity SOC in the condition of the battery, the lower the target cranking speed N* of the engine is set, and the motor is driven by using a power from the battery at the target cranking speed N* to perform the cranking of the engine. Thus, since the power of the battery is assured so that the engine can be re-started after the engine fails to start, the engine is more surely started. COPYRIGHT: (C)2004,JPO

解决方案：在发动机状态下冷却发动机的冷却介质的温度T越低，在电池状态下的剩余容量SOC越低，发动机的目标起动转速N *越低 并且通过使用来自电池的目标起动转速N *的动力来驱动电动机以执行发动机的起动。 因此，由于确保电池的功率，使得发动机能够在发动机起动不能起动之后重新启动发动机，所以更可靠地启动发动机。 版权所有（C）2004，JPO

Abstract: PROBLEM TO BE SOLVED: To ensure emission purifying performance of a plug-in hybrid vehicle, without giving discomfort to a user during shifting from CD mode for preferentially using a motor to CS mode for using an engine and the motor. SOLUTION: An ECU that controls a plug-in hybrid vehicle starts an engine when a required power P as a value obtained by subtracting a required discharge amount Pout from a drive power is larger than a threshold P1 and stops the engine when the required power P is smaller than a threshold P2 during intermittent control in the CD mode. When intermittent control is performed in the CD mode (YES in S100, YES in S102), the ECU limits the required discharge amount Pout to a relatively small value in a range where an engine coolant temperature THw is low, and sets the required discharge amount Pout relatively large without imposing any limitation thereon in a range where the engine coolant temperature THw is high (S116).

SOLUTION: A hybrid vehicle 100 is mounted with an engine 2 and a motor generator MG2 as a power source for vehicle travelling.

Consequently, misfire of the engine in the hybrid vehicle can be accurately detected.

Abstract: PROBLEM TO BE SOLVED: To reduce a control load resulting from such a fact that storage in a storage means cannot be performed by a catalyst deterioration suppressing control.
SOLUTION: When an input limit value WIN exceeds a limit amount WIN1 (YES in S118) when an exhaust gas purification catalyst comes within a catalyst deteriorating hot area when the requirements for fuel cut are established, i.e, the braking energy of a motor MG2 when the catalyst deterioration suppressing control is performed cannot be stored in a battery, a special control is not performed but an execution instruction for fuel cut control is outputted to an engine ECU (S110). Accordingly, a control load needed is small. In this case, since an exhaust gas temperature is lowered by an increase in OT before the input limit value WIN exceeds the limit amount WIN1, a catalyst bed temperature is lowered and, therefore, the catalyst deterioration is difficult to advance.

Abstract: PROBLEM TO BE SOLVED: To promptly output power based on demands of a driver while suppressing vibration upon starting of an internal combustion engine.
SOLUTION: When automatically starting an engine, upon a normal engine start, the amount of intake air is reduced by tightening the opening of a throttle valve (S140). When the driver presses down hard on the accelerator pedal, and an engine request power Pe* is a threshold value Pref or more, the throttle valve opening is an opening according to the request engine power Pe* (normal opening) and the amount of intake air is an amount corresponding to the engine demand power Pe* (S150). Cranking is performed to start the engine. Thereby, on a normal start of the engine, vibration at initial explosion can be suppressed, and when the requested engine power Pe* is large, driving power from the engine can be promptly outputted.
