摘要： A vehicle control device applied to a vehicle including an internal combustion engine and an electrically heated catalyst which is warmed by applying a current, and includes a catalyst carrier supporting a catalyst and a carrier retention unit that retains the catalyst carrier and has an electrical insulation property. The control unit performs a control of suppressing a supply of an unburned gas from the internal combustion engine to the electrically heated catalyst so that the carrier retention unit is maintained at a lower temperature than the catalyst, when a condition for performing a fuel cut of the internal combustion engine during a deceleration is satisfied. Therefore, it is possible to suppress a rapid cooling of the catalyst, and it becomes possible to maintain a temperature of the carrier retention unit at a lower temperature than a temperature of the catalyst.

摘要： A fuel tank is divided into a fuel chamber and an air chamber by a bladder diaphragm. Under a condition that both the amount of intake air Ga and the engine revolution speed NE of an internal combustion engine are kept at constant values, a vapor concentration correction factor FGPG during a fuel injection duration TAU is calculated based on a change in the air-fuel ratio detected when gas is purged from the air chamber toward an intake passage of the engine. Based on the vapor concentration correction factor FGPG, it is determined whether there is fuel leakage from the fuel chamber to the air chamber. With this determination technique, a fluctuation in the air-fuel ratio is not caused by a situation where the engine is in a transitional state, during fuel leakage detection, so that the vapor concentration correction factor FGPG assumes a proper value corresponding to the vapor concentration in the air chamber. Therefore, a false determination regarding the presence/absence of fuel leakage from the fuel chamber to the air chamber is prevented.
摘要翻译：燃料箱通过气囊隔膜分成燃料室和空气室。在内燃机的进气量和发动机转速NE都保持为恒定值的条件下，基于空燃比的变化来计算燃料喷射持续时间TAU期间的蒸汽浓度校正系数FGPG，当气体从空气室朝向发动机的进气通道被清除时，检测到燃料比。基于蒸气浓度校正因子FGPG，确定是否存在从燃料室到空气室的燃料泄漏。利用该判定技术，在燃料泄漏检测时，由于发动机处于过渡状态的情况，不会引起空燃比的波动，所以蒸气浓度校正系数FGPG取相当于蒸气浓度的适当值在空气室。因此，能够防止燃料从燃料室向气室的泄漏的存在/不存在的错误判定。
