    • In a hybrid vehicle of the invention, the control procedure corrects an idling intake air flow Qidl to enable an engine immediately after its start to generate an output power Pe that is substantially equivalent to an engine power demand Pe*. After the correction, the control procedure controls the engine to have an intake air flow Qe with reflection of an intake air flow correction value Qec and controls a motor MG1 to generate electric power by using the output power Pe of the engine and to charge a battery with the generated electric power within an input limit Win of the battery. The control of the invention ensures that the output power Pe of the engine does not exceed the engine power demand Pe* in restriction of the charge level of the battery. This arrangement effectively prevents the state of charge SOC of the battery, which is charged with the electric power generated by the motor MG1, from exceeding the input limit Win.

    • The engine misfire detection apparatus of the invention successively determines whether a rotational fluctuation difference Nxd360 as a difference between a rotational fluctuation Nxd at a certain crank angle CA of an engine and a rotational fluctuation Nxd at a 360 degree-prior crank angle CA exceeds a predetermined reference value A1 (step S150) and whether a rotational fluctuation difference Nxd720 as a difference between the rotational fluctuation Nxd at the certain crank angle CA and a rotational fluctuation Nxd at a 720 degree-prior crank angle CA exceeds a predetermined reference value B1 (step S160). The engine misfire detection apparatus detects a misfire of the engine upon satisfaction of all conditions regarding rotational fluctuation difference proportions Nja2, Nja3, and Nja4 on the basis of the rotational fluctuation difference Nxd360 (step S200) and all conditions regarding rotational fluctuation difference proportions Njb2, Njb3, and Njb4 on the basis of the rotational fluctuation difference Nxd720 (step S210), when both the rotational fluctuation differences Nxd360 and Nxd720 exceed the respective reference values A1 and B1 (steps S150 and S160). This arrangement ensures adequate and accurate detection of an engine misfire during warm-up of a catalyst included in an exhaust emission control unit with a significant delay of the ignition timing in the engine.

    • In response to simultaneous ON settings of a heater switch signal HSW and an eco switch signal ESW, an eco priority map is set to an intermittent operation permission map (step S350). The heater switch signal HSW is output from a heater switch that is operated to warm up a passenger compartment, while the eco switch signal ESW is output from an eco switch that is operated to give preference to improvement in fuel consumption of the vehicle over the heater function. The eco priority map is designed to allow intermittent operation of an engine in a lower range of cooling water temperature Tw of the engine than that in a heater-on state map set in response to OFF setting of the eco switch signal ESW and ON setting of the heater switch signal HSW. The control procedure of the invention refers to the intermittent operation permission map and determines whether the intermittent operation of the engine is allowed or prohibited, based on the current cooling water temperature Tw and a starting-time cooling water temperature Tst, which represents a temperature of cooling water at a first start of the engine since activation of the vehicle system (step S360).

    • In a hybrid vehicle of the invention, in the event of specification that an exhaust treatment catalyst is in a preset adequate state at step S112, combustion control of an engine starts after a decrease of an intake pipe pressure P to a preset reference negative pressure Pref and reduction of an intake air flow into a cylinder of the engine by engine motoring. In the event of specification that the exhaust treatment catalyst is not in the preset adequate state but in an inadequate state at step S112, on the other hand, the combustion control of the engine immediately starts, prior to the decrease of the intake pipe pressure P to the preset reference negative pressure Pref. The hybrid vehicle of the invention allows an early start of the combustion control in a lower catalyst temperature condition that lowers the catalytic conversion power of the exhaust treatment catalyst and in a higher catalyst temperature condition that causes accelerated deterioration of the exhaust treatment catalyst in exposure to the air. The early start of the combustion control effectively reduces the potential shocks on a start of the engine, while preventing the potential troubles, for example, the worsened emission and the accelerated deterioration of the exhaust treatment catalyst, arising in the course of engine motoring due to the inadequate state of the exhaust treatment catalyst.
    • 在本发明的混合动力车辆中,在步骤S112中规定废气处理催化剂处于预先设定的适当状态的情况下,发动机的燃烧控制在进气管压力P降低至预先设定的基准负压 通过发动机起动来减少进入发动机气缸的进气流量。 在规定废气处理催化剂不处于预设适当状态但在步骤S112处于不充分状态的情况下,发动机的燃烧控制在进气管压力降低之前立即开始 P到预设参考负压Pref。 本发明的混合动力车辆能够在较低的催化剂温度条件下早期开始燃烧控制,其降低排气处理催化剂的催化转化率,并且在较高的催化剂温度条件下,导致废气处理催化剂暴露于 空气。 燃烧控制的早期开始有效地减少了发动机起动时的潜在冲击,同时防止了在发动机运转过程中引起的排气处理催化剂的恶化和加速劣化等潜在的问题, 废气处理催化剂的状态不足。
