Abstract
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.
