    Abstract: An ECU for controlling an engine counts the continued period of stopping the engine in a low-temperature environment. The ECU sets the idle rotational speed at a first idle rotational speed when the stopped period is below a predetermined threshold value, and at a second idle rotational speed higher than the first idle rotational speed when the stopped period exceeds the reference value. Accordingly, resonance at the driving force transmission system during idle operation can be prevented even in the case where a mount employed for attaching the engine to the vehicle is hardened as a result of undergoing a low-temperature environment for a long period of time, and the resonant rotational speed of the driving force transmission system including the engine varies.

    Abstract translation: 用于控制发动机的ECU计算在低温环境中停止发动机的持续时间。 当停止时段低于预定阈值时，ECU将怠速旋转速度设定在第一空转速度，当停止时间超过参考值时，将其设定为高于第一怠速转动速度的第二空转转速。 因此，即使在用于将发动机安装到车辆上的安装座由于经受长时间的低温环境而硬化的情况下也能够防止怠速运转期间的驱动力传递系统的共振，并且 包括发动机的驱动力传递系统的共振转速变化。

    Abstract: Disclosed is a control device applied to an internal combustion engine provided with a fuel vapor treatment system for treating collected fuel vapor by purging the collected fuel vapor into intake air downstream from an air flowmeter (6) and an exhaust gas recirculation system for recirculating part of exhaust gas in the intake air using intake negative pressure. An electronic control unit (22) performs an advance correction corresponding to the exhaust gas recirculation quantity regarding the MBT ignition timing and the knock limit ignition timing, and corrects the volumetric efficiency of the internal combustion engine, which is used for the calculation of the advance correction quantity used for the advance correction, according to the purge air quantity. Consequently, regardless of the decrease of the exhaust gas recirculation quantity caused by the implementation of a large quantity of purge, the appropriate advance corrections of the MBT ignition timing and the knock limit ignition timing become possible.

    Abstract: An object of the present invention is to provide a control device for a vehicle which enables prompt warm-up, and a vehicle including the same. When a control state of the vehicle is a started state (Ready-ON state), a float valve disconnects a first oil pan from a second oil pan in any of cases where an engine is in an operational state and in a stopped state, and, when the control state of the vehicle is a stopped state (Ready-OFF state), the float valve provides communication between the first oil pan and the second oil pan.

    Abstract: An inter-cylinder air-fuel ratio imbalance abnormality detection apparatus includes an air-fuel ratio sensor disposed in an exhaust passage of a multi-cylinder internal combustion engine, and an abnormality detection unit that detects an inter-cylinder air-fuel ratio imbalance abnormality on the basis of a degree of variation in an output of the air-fuel ratio sensor. The abnormality detection unit detects the inter-cylinder air-fuel ratio imbalance abnormality by comparing a value of a parameter that correlates with the degree of variation in the output of the air-fuel ratio sensor with a predetermined abnormality determination value. The abnormality determination value is set individually for each of a plurality of preset operating regions of the internal combustion engine.
