    Abstract: PROBLEM TO BE SOLVED: To restrain degradation in an engine from proceeding even though automatic start and stop of the engine are repeated.
    SOLUTION: Automatic stop time-period T of the engine 20 is not substantially limited before the number of times N of starting in an oil-film runout state (the number of times of starting the engine 20 in an oil-film runout state) reaches N1, but after the number of times N of starting in an oil-film runout state has reached N1, the automatic stop time-period is limited. Particularly when the number of times N of starting in an oil-film runout state has reached a threshold Nthr, the stop permissible time Tp is set at oil-film runout time limit Tlim. As a result, when the automatic stop time-period T exceeds the Tlim, the engine 20 is automatically started. When the number of times N of starting in an oil-film runout state has reached the threshold Nthr, even though the engine 20 has automatically stopped, the engine is not started in the runout oil-film state, so the engine degradation hardly proceeds.

    Abstract translation: 要解决的问题：即使重复发动机的自动启动和停止，也可以抑制发动机的劣化。

    解决方案：在油膜跳动状态下启动次数N（油膜跳动中启动发动机20的次数）之后，发动机20的自动停止时间段T基本上不受限制 状态）达到N1，但是在油膜跳动状态起动次数N达到N1以后，自动停止时间段受到限制。 特别是当在油膜跳动状态下启动的次数N达到阈值Nthr时，停止允许时间Tp被设定为油膜跳动时间限制Tlim。 结果，当自动停止时间段T超过Tlim时，发动机20自动启动。 当油膜跳动状态下的起动次数N达到阈值Nthr时，即使发动机20自动停止，发动机也不会在跳动油膜状态下起动，所以发动机劣化几乎不进行。 版权所有（C）2006，JPO＆NCIPI

    Abstract: PROBLEM TO BE SOLVED: To decide the degree of fatigue of a rotation system connected to an internal combustion engine, with higher accuracy. SOLUTION: When resonance phenomena occur in a rotation system connected to an engine of rotational frequency Ne because of the change in its rotational frequency (S110), an input torque Tlim which acts on the rotation system as the size of resonance phenomena Ne is measured based on the size of change of this rotational frequency (S120). An endurance time tlim of a rotation system in the case assuming that this input torque Tlim continued and acted is set up. A fatigue degree ΔS of a rotation system per unit time is calculated, by dividing the unit time to (execution period of a routine) by the endurance time tlim (S130 to S140), and degree of fatigue S of a rotation system is calculated by integrating this (S150). When the fatigue degree S reaches a value 1, a warning display is made as the limit of fatigue (S160, S170). Thereby, the fatigue degree for a rotation system can be decided more accurately.

    解决方案：由于旋转频率Ne的发动机连接到旋转系统的发动机的旋转系统发生共振现象（S110）时，作为旋转系统的输入转矩Tlim作为共振现象的大小Ne 基于该转动频率的变化的大小来测量（S120）。 在假设该输入转矩Tlim持续并起作用的情况下，旋转系统的耐久时间tlim被建立。 通过将单位时间（例程的执行期间）除以耐久时间tlim（S130〜S140），计算旋转系统的疲劳程度ΔS，旋转系统的疲劳度S由 整合（S150）。 当疲劳度S达到值1时，将作为疲劳极限的警告显示（S160，S170）。 由此，可以更准确地确定旋转系统的疲劳度。 版权所有（C）2005，JPO＆NCIPI

    Abstract: PROBLEM TO BE SOLVED: To solve a problem that it may be impossible to effectively collect warm water in a heat storage system for an internal combustion engine.
    SOLUTION: When an ECU refers to a hysteresis of an accelerator opening, and determines that the accelerator opening (S10a) is small, it is supposed that a peak value and a mean value in the temperature of cooling water for the internal combustion engine are low, and lowers a warm water collection starting temperature from an initial value (S12). When it is supposed that the accelerator opening is in an average (S10b), a collection starting temperature is left to be the initial value (S14) as it is. When it is supposed that the acceleration opening is great (S10c), a warm water collection starting temperature is raised from the initial value (S16).

    Abstract: PROBLEM TO BE SOLVED: To provide electric power supply structure capable of effectively supplying electric power to a temperature raising device for an in-vehicle instrument. SOLUTION: The temperature raising device for the in-vehicle instrument makes an electric motor and an internal combustion engine 11 be drive sources, and is applied for a hybrid vehicle equipped with an inverter 17 with a converter which lowers output voltage of an HV battery 16 to DC14V and inputs it to an auxiliary machine and an auxiliary machine battery 23. When cooling water stored in a thermal storage tank 21 is supplied to the internal combustion engine 11 with an electric water pump 22 to raise the temperature of the engine 11, the water pump 22 is driven by the output voltage from the HV battery 16 lowered to DC14V through the inverter with the converter. When the cooling water is stored into the thermal storage tank 21 in accompany with the turning-off of an ignition switch, the water pump 22 is driven with DC12V from the auxiliary machine battery 23.

    Abstract: PROBLEM TO BE SOLVED: To avoid the situation of becoming in capable of restarting a driving force source after stopping the specific driving force source. SOLUTION: Before automatic stopping processing of an engine, determination is made on whether or not the engine can be restarted by a starter MG. When determining that the engine is in a condition that power generation is performed by the starter MG (YES in Step 110), power generation processing by the starter MG is performed (Step 110). Next, when determining that the power generation in normally performed by the starter MG (YES in Step 130), a starter MG normal flag exstmg is set to ON (Step 140). When determining that the power generation is not normally performed (NO in Step 130), the starter MG normal flag exstmg is set to OFF (Step 150). COPYRIGHT: (C)2004,JPO

    Abstract: PROBLEM TO BE SOLVED: To provide a hybrid vehicle that starts an engine at more proper timing and travels. SOLUTION: When an electric travelling mode that prioritizes electric travelling to travel by using an only power outputted from motor 42 is set, the longer an engine stopping time (tstp) when the engine 32 is stopped, the lower speed is set to electric travelling permission speed Vpm (S130). When a vehicle speed V is larger than the electric travelling permission speed Vpm while the engine 32 is being stopped, the engine 32 and motors 41 and 42 are controlled to be travelled with a requested torque by starting the engine 32 (S140, S160).

    Abstract: PROBLEM TO BE SOLVED: To eliminate air pockets in two system pipes without spouting fuel in an internal combustion engine including the two system fuel supply pipes. SOLUTION: A fuel supply system 11 is provided with a check valve 412 in a low pressure delivery communication pipe 410 and a check valve 422 in a pump supply pipe 420. The check valve 412 does not allow fuel to flow from a low pressure delivery pipe 122 side to a low pressure supply pipe 400 side. The check valve 422 does not allow fuel to flow from the pump supply pipe 420 side to the low pressure supply pipe 400 side. An engine ECU 10 opens a cylinder injection injector 110 and a suction air passage injection injector 120 for dummy injection after operating a feed pump 100 for about one second when it is judged that air bleeding is necessary.
