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 vehicle control device includes an insulation resistance determination unit which determines whether or not an insulation resistance of the carrier retention unit decreases to a value equal to or lower than a predetermined value, and an applying current prohibition unit which prohibits applying the current to the electrically heated catalyst when the insulation resistance determination unit determines that the insulation resistance decreases to the value equal to or lower than the predetermined value. Therefore, it is possible to appropriately control of applying the current to the electrically heated catalyst based on the insulation property of the carrier retention unit, and hence it becomes possible to appropriately prevent an electrical leak of the electrically heated catalyst.

摘要： The present invention is intended to provide a technique which is capable of improving detection accuracy at the time of performing failure detection of a particulate filter by the use of a PM sensor. In the present invention, the PM sensor is arranged in an exhaust passage at the downstream side of the particulate filter. Then, the presence or absence of a failure in the particulate filter is determined by making a comparison between an output value of the PM sensor at the time when a predetermined period of time has elapsed after the execution of PM removal processing to remove the particulate matter deposited on the PM sensor is completed, and a predetermined threshold value. At this time, the threshold value is set based on an average value of an amount of intake air in an internal combustion engine during the passage of the predetermined period of time.
