Control apparatus of vehicle

摘要

In a vehicle, which is provided with: a primary turbo and a secondary turbo, each of which is of an exhaust driven type; an exhaust changeover valve and an intake changeover valve, which are placed in a secondary exhaust passage and a secondary intake passage corresponding to the secondary turbo, respectively; and an intake bypass valve placed in an intake bypass passage, an ECU sets the opening/closing state of each changeover valve to an opening/closing state corresponding to a twin turbo mode at the time of engine stop, and it uses the drive control of each changeover valve which is necessitated in the transition to a single turbo mode at the engine start, thereby performing the sticking detection of the changeover valve at the same time.

1. A control apparatus of a vehicle,
the vehicle comprising: an internal combustion engine; a supercharging system including a first supercharger and a second supercharger each of which is driven by an exhaust gas of the internal combustion engine; and at least one changeover valve which is placed in at least one of an intake passage and an exhaust passage of the internal combustion engine and which changes a supercharging mode associated with the supercharging system among a plurality of supercharging modes including a single supercharging mode for performing supercharging only with the first supercharger and a twin supercharging mode for performing supercharging with both the first and second superchargers, in accordance with an opening/closing state, said control apparatus comprising: a first controlling device which is configured to control the changeover valve at the time of engine stop of the internal combustion engine such that the opening/closing state is an opening/closing state corresponding to a supercharging mode which is different from a supercharging mode to be selected at the start of the internal combustion engine and which is to be selected in an operating area on a higher-load side than at the start from among the plurality of supercharging modes; and a second controlling device which is configured to control the changeover valve at the start of the internal combustion engine such that the opening/closing state is an opening/closing state corresponding to the supercharging mode to be selected at the start.
